Oracle Database 11g XE Installer Error

Oracle 11g XE Installer

Finally, I got to install Oracle Database 11g Express Edition (XE) tonight. Unfortunately, I ran into an error during the installation. A quick Google search landed me in the forum, where it gave me the impression it wouldn’t work on Windows 7, 64-bit. However, I’m tenacious with problems like this. Here’s the screenshot for the error:

The text from the image is noted below to help folks find the solution.

The installer is unable to instantiate the file C:\Users\McLAUGH~1\AppData\Local\Temp\{078E83D7-3FCC-4A72-903B-995C7CE44681}\KEY_XE.reg. The file does not appear to exist.

The physical file isn’t missing, what failed to happen was that the installer didn’t write a Registry Key’s Data value. You can add the missing registry key’s Data value, and then click OK on the Error dialog box to continue the installation. (Replying to Andrea, I’ve provided screen shots on editing the Registry in a comment below.) It will succeed, at least it succeeded for me on Windows 7 64-bit. Rather than use abbreviations like the forum entry, the missing key is found here in the Windows Registry:

- HKEY_CLASSES_ROOT\Installer\Products\266B7A503A089BE4EAD1986A429434C1\SourceList\Media

A screenshot shows that the Data value of the key wasn’t populated by the MSI (Microsoft Software Installer), the arguments remain for a script to populate:

You need to add the message value from your Error dialog as Data value of the Name entry 1, like this screenshot shows:

Since I believe the only things that should change are your Administrator’s hostname and the key value (type in the one that shows in the your dialog box), here’s the text you’ll need to enter:

C:\Users\hostname\AppData\Local\Temp\{078E83D7-3FCC-4A72-903B-995C7CE44681}\

This fix worked for me, and I hope the same holds true for you.

Kris Rice did tweet that a Win 64 bit version of XE “is in the works”

Good job man!!

it’s worked for me.

Hi,

It’s true, this method will solve the bug, but the home page hasn’t shown yet.

Maybe the ports not good (because of the TNS Service doesn’t run). How can I change the ports under the installation?

Updated the post to ensure everyone knows that the key value can differ and you need to type in the one shown in your error message dialog box.

You can check Step #7 in this post. I’d suggest you uninstall and re-install. Also, make sure that you enter the key value from your error message. They can differ.

Hi,
I am also getting the same issue pop up(The installer is unable to instantiate the file C:\Users\SAMRAT\AppData\Local\Temp\{some value..}\KEY_XE.reg), so according to this blog I went to the path mentioned in the error pop up but could not find out the file “KEY_XE.reg” where I will set up the key data value.I am also installing in Windows7 64 bit.The DB installation file is “OracleXE112_Win32″.Please help me in resolving this issue.Thanks

Samrat

Hi,
Those who have successfully resolved the above issue please let me know the step by step procedure how you have successfully set up this value after getting the error pop up.Thanks.

You make the change in the registry. Use regedit to edit the registry.

24 Oct 11 at 12:43 pm

I have Windows 7 x64 and a got the problem about the KEY_XE.reg not fount. I have tried a lot of configurations I have finally solved.

We need do some thinks:

1. Start the installer ‘Setup.exe’. Wait until asked about the path.
2. Do not press next. Open with Windows Explorer the folder like this:

C:\Users\\AppData\Local\Temp{60712028-B7B0-4EC3-9C28-663111EC954A}

3. There will be a file OracleMTSRecoveryService.reg. Make a copy and rename the copy to KEY_REG.reg
4. Go to the installer and go ahead with the installation.

You will not see any error about the KEY_XE.reg not found.

Now, you need check your hostname and localhost. Open the file C:\Windows\System32\drivers\etc\hosts and check if you have something like this:

127.0.0.1 localhost
192.168.1.20 your_pc_hostname

The second line is your IP, this one is an example. Try to stop and start the Oracle Express by the shortcut at the start menu. To check if all Oracle services are running, use this command:

C:\Oracle\oraclexe\app\oracle\product\11.2.0\server\bin&gt;lsnrctl status

The result:

You cannot see the services “xe”, so you need do fix the listener.ora at

D:\Oracle\oraclexe\app\oracle\product\11.2.0\server\network\ADMIN\listener.ora

If your hostname or localhost didn’t work, so put your PC IP, like this:

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = D:\Oracle\oraclexe\app\oracle\product\11.2.0\server)
(PROGRAM = extproc)
)
(SID_DESC =
(SID_NAME = CLRExtProc)
(ORACLE_HOME = D:\Oracle\oraclexe\app\oracle\product\11.2.0\server)
(PROGRAM = extproc)
)
)
 
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.20)(PORT = 1521))
)
)
DEFAULT_SERVICE_LISTENER = (XE)

Maybe can be necessary fix the D:\Oracle\oraclexe\app\oracle\product\11.2.0\server\network\ADMIN\sample\LISTENER.ORA, put the IP too. Like this:

# LISTENER =
# (ADDRESS_LIST=
# (ADDRESS=(PROTOCOL=tcp)(HOST=192.168.1.20)(PORT=1521))
# (ADDRESS=(PROTOCOL=ipc)(KEY=PNPKEY)))

If you try open the apex by the Windows start menu and get the error http://127.0.0.1:%HTTPPORT%/apex/f?p=4950. It is easy:

Go to D:\Oracle\oraclexe\app\oracle\product\11.2.0\server and click over the file Get_Started and choose properties, there change the %HTTPPORT% for you port, usually 8080, will be like this:

http://127.0.0.1:8080/apex/f?p=4950

Pay attention, I have installed Oracle Express 11g at D:\Oracle.

Where exactly do I edit in regedit? Where do I find this – HKEY_CLASSES_ROOT\Installer\Products\266B7A503A089BE4EAD1986A429434C1\SourceList\Media?

I can’t find anything remotely similar to that

Here’s how you open regedit.exe from Windows:

I can get to regedit but the rest I have no clue what to do.

Andrea

1 Nov 11 at 4:10 am
Andrea,

You should see the following when you launch the Windows 7 Registry:

Click on the arrow symbol to the left of the HKEY_CLASSES_ROOT node to expand the node tree. Scroll down until you find the Installer node and click the arrow symbol to expand the node tree another level. Repeat the process for the Product, Product Key Value, and SourceList nodes, as displayed below.

Click on the Media node, which is a leaf node in the Registry tree. Click on the Name 1 and then click the Edit menu option. Within the drop down menu, click on the Modify… option to edit the Data value.

Enter the fully qualified Value data value, which should include the key value provided in the error dialog from the Oracle Installer.

I hope this helps you fix your installation problem.

See! Nothing to it. This is how installers should work, right?

Oracle’s installer, what a humorless joke…

Bill Kuhn

23 Nov 11 at 3:07 pm
Your fix by filling in the key worked like a champ for me. I filled it in using Regedit while the error message was still up, then had to hit enter twice to get beyond the error message. Installation took a while to finish but once it was done I can get to my Getting Started page w/o problem.

Thanks!

Oracle’s install is still a monumental fail, as it is.

After fixing this issue, I was having a lot of problems starting the database and connecting to http://localhost:8080/apex url… Until I realized that I was installing the Oracle 11g XE on a 64 bit using a 32 bit installer. When I tried installing on the 32 bit system, I no longer got this error message.

Pegah

28 Nov 11 at 4:49 am
Thank you so much, the installation worked just perfect.
Now my alert log fills rapidly with
“OER 7451 in Load Indicator : Error Code = OSD-04500: illegal option specified”
As per Oracle:
nstalled 32-bit Oracle database software on a 64-bit MS Windows OS which is not supported.

And yes, it is 32-bit db on 64-bit os. Any idea how to resolve the error or at least to suppress it?

Thanks!

Hey everyone
Let me give you a senario about my installation of Oracle XE11g 32-bit in my laptop:

Actully, I am having Win7 OS but it’s 64-bit ! ! !
I install XE11g 32-bit on it and I got the error mentioned above but it did not harm anything. In fact installation went on successfully. Then I installed Oracle Developer6i along with it to run my applicatioin and it works also fine…
I dump few data using export import steps and that also went perfect so when i start running the application it works fine….now the proplem occur when i run the report… the system hangs where I am using same application with same XE11g 32-bit in Win XP with no problem at all! ! ! !
anyone has faced this propblem????

Nice Article, really helpful in resolving XE installation issue.

@Eder: Thank you for the step by step, just one change in my case – For Step 3. There will be a file OracleMTSRecoveryService.reg. Make a copy and rename the copy to KEY_XE.reg instead of KEY_REG.reg.

Vipul

29 Dec 11 at 8:46 pm

Nice Article, like Vipul I’d to rename the file at step3 to KEY_REG.reg to avoid the error message.

However i cannot get the XE to launch.

I’m missing:

(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=zetared-pc)(PORT=8080))(Presentation=HTTP)(SESSION=RAW))

And

O Service "XEXDB" tem 1 Instance(s).
Instance "xe", STATUS READY, has 1 handler(s) FOR this service...
O service "xe" has 1 Instance(s).

Try the following, and make sure your listener.ora and tnsnames.ora use zetard-pc.
1 2 3
127.0.0.1 localhost ::1 localhost 127.0.0.1 zetard-pc zetard-pc.domain

Hi,
I have installed successfully without modifying reg. It went fine after clicking OK without modifying error message. Does it mean, I am ok with the installation. Or do i need to uninstall and reinstall with registry fix. is it the last registry to be edited among all the entries for products in the list. Please let me know.

Sometimes, it does work. Most times, it doesn’t. It appears you’re lucky.

Thanks for the quick feedback. I was not able to find our the right key to edit. After clicking ok, I was not able to stop the installer in order to enter the key. I got successful installation message at the end. I am assuming that, everything if fine with my installation. Let me know if i need to reinstall the software.

Windoze 7 64 bitzzz. Followed the registry key manual edit by copying the error message I got… the installer ended successfully (that’s what it reported), then hangs. I’m stuck, installation won’t end, step 7 of the installation will never fire up. Oracle XE 11g => FAIL.

You can try it again, or you can install Oracle Database 11g R2. The latter works well.

I have the same issue as William (posted on 17 Jan). My DB and listener are up and running but my Get Started page does not come up. I even tried installing Oracle 11g R2 but getting war file and ear file missing errors and not able to complete installation. Any suggestions? I have Windows 7 64 bit. I have tried lot of options for more that 4 days now.

Veena

10 Feb 12 at 9:29 am
Did you save a copy of your Windows registry before you attempted the Oracle Database 11g XE installation? If so, did you recover to that registry before attempting to install Oracle Database 11g? If the answers to either of these is no, that’s most likely the problem.

You typically have three options after a failed Oracle Database installation, recover to a saved registry state, manually cleanup the registry and file system, or re-install the Windows operating system. The get started page is a link and editable. Dependent on what you did, you can edit the file. My guess is you’ll be fine if you edit it since everything else is working. You can do that by right clicking on the menu option, then choose properties. I’ve got a hunch that the link is looking for Oracle Database 11g XE not what you’ve got installed.

10 Feb 12 at 10:42 am

I have had the same issues. I’ve worked through the rededit fix but I don’t have any “xe” services showing. Does that mean the regedit fix did’t work? What does a functional listener.ora look like? Does it have the “xe” services in it?

I can successfully tnsping my listener with HOSTNAME, LOCALHOST, and IPs for HOSTNAME and LOCALHOST. I’m confident my listener is working. I’m missing the default services I think but I’m not sure what they are.

Looks like the listener is up and running, the networking files are in the %ORACLE_HOME%/network/admin directory. You can check for a working service by opening a command shell and typing the following (it’s easier than posting the navigation steps that change by version of Windows):

C:\> services.msc

I’ve posted this a few times trying to help folks creating their own Windows 7 service. It’s done with the ORADIM utility. ORADIM creates, maintains, and deletes Windows services for the database.

Create an instance by specifying the following options:

ORADIM -NEW -SID sid | -SRVC srvc | -ASMSID sid | -ASMSRVC srvc [-SYSPWD pass] [-STARTMODE auto|manual] [-SRVCSTART system|demand] [-PFILE file | -SPFILE [-SHUTMODE normal|immediate|abort] [-TIMEOUT secs] [-RUNAS osusr/ospass]

Edit an instance by specifying the following options:

ORADIM -EDIT -SID sid | -ASMSID sid [-SYSPWD pass] [-STARTMODE auto|manual] [-SRVCSTART system|demand] [-PFILE file | -SPFILE] [-SHUTMODE normal|immediate|abort] [-SHUTTYPE srvc|inst] [-RUNAS osusr/ospass]

Delete instances by specifying the following options:

ORADIM -DELETE -SID sid | -ASMSID sid | -SRVC srvc | -ASMSRVC srvc

Startup services and instance by specifying the following options:

ORADIM -STARTUP -SID sid | -ASMSID sid [-SYSPWD pass] [-STARTTYPE srvc|inst|srvc,inst] [-PFILE filename | -SPFILE]

Shutdown service and instance by specifying the following options:

ORADIM -SHUTDOWN -SID sid | -ASMSID sid [-SYSPWD pass] [-SHUTTYPE srvc|inst|srvc,inst] [-SHUTMODE normal|immediate|abort]

Query for help by specifying the following parameters:

ORADIM -? | -h | -help

I just Google’d to see if there was a page with some additional definitions for folks. You can also find additional information here.

[...] Once I downloaded it I merely ran the Disk1setup.exe file. It was mostly straightforward, but I ran into a little hitch during the installation. It is possibly because I am installing a 32 bit Oracle database onto a 64 bit Windows 2008 R2 server. Luckily I found the work around at this link: http://blog.mclaughlinsoftware.com/2011/09/13/oracle-11g-xe-installer/ [...]

I followed the instructions for install and installed correctly but couldn’t connect via sqlplus to xe, then I did a trawl of the web and found problems related to the Windows Event viewer (Windows Event Log service not started). I then did another trawl and managed to the get event log service running by modifying the permissions on eventlog folder, re-booting, then uninstalled xe and removed oraclexe folder, then I re-installed updated by listener.ora to this:

      (ADDRESS=  (PROTOCOL = tcp)(HOST = 127.0.0.1)                    (PORT = 8080))
    )
  )
 
DEFAULT_SERVICE_LISTENER = (XE)

I then ensured my tnsnames.ora matched the host name like this:

XE =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = WGC1W7GJQB65J.warley.ford.com)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = XE)
    )
  )
 
EXTPROC_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
    )
    (CONNECT_DATA =
      (SID = PLSExtProc)
      (PRESENTATION = RO)
    )
  )
 
ORACLR_CONNECTION_DATA = 
  (DESCRIPTION = 
    (ADDRESS_LIST = 
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1)) 
    ) 
    (CONNECT_DATA = 
      (SID = CLRExtProc) 
      (PRESENTATION = RO) 
    ) 
  )

I then stopped and re-started the listener via lsnrctl.exe and I was able to connect to XE via sqlplus and via sqldeveloper. However I still cannot connect to the web front-end (apex), but I am a lot happier than I was 2 days ago when this suddenly stopped working.

i found a problem in oracle 11g xpress edition installation….it shows messag
appdata/local/temp{165FCD36-DD30-49D3-A420-3D1A6A70A7C6}\KEY_XE.REG does not appear.........
can anybody help me to resolve this problem…..thanking you
deep

The solution for me was the one maclochlainn provided. Thank you.

1) All I had to do was just double click the Oracle setup.exe file, but don’t do anything. Don’t cliect next yet.

2) The setup program will create 2 additional temp directories initially in C:\Users\V252112\AppData\Local\Temp\{….}

- What you need to look for is one of the three directories that look like {5ECC178F-4652-4BB1-9256-8C836685EED6} as an example. Not exactly this number.

- In one of them, the installer will create a file called “OracleMTSRecoveryService.reg”, just make a copy of this file in the same directory and name it KEY_XE.reg.

3) Continue with your installation.

4) Finish

THAT IS IT.

It should work.

Thank you for the solution.

I followed this workaround and the installation appeared to work but cannot log in to Apex (http://localhost:8087/apex). It is saying invalid credentials. I know the password I set up is correct. Any ideas?

And I did not add the KEY_XE.reg to the end of the path for the key value in the registry. Could that be the problem? I did not add that because in your screenshots you did not appear to add it to yours.

17 Apr 12 at 8:45 am
On my Win 2008R2 it was enough to copy OracleMTSRecoveryService.reg into KEY_XE.reg and proceed with installation.

Many thanks for this information. I tried twice to install this. The second time worked with this information. I just had to make the registry change listed above and then set the port for the Gwt_started shortcut error: http://127.0.0.1:8080/apex/f?p=4950 and it came up fine.

hi
I have a problem connecting to the oracle db via the sql developer.I instaled the 11g xe 32 bit on a 64 win7 platform. when I triied to build a connection i get this message :
c:\oraclexe\app\oracle\product\11.2.0\sever\bin\ocijdbcll.dll:can't load IA 32 bit dll on an AMD 64-bit platform.
this problem does’t occour when I use the sql command prompt.
How can I fix it?
Josef

5 Oct 12 at 4:33 am
hi, I ve done anything in my power but nothing works.

I ve modify the registry, never found the Key_xe.reg so i ve renamed theo nly reg file in the temp directory in this name. I have no response rom the 12.0.0.1:8080/apex
and also when i try the sql command with connect it says always the same:
ORA-01089: immediate shutdown IN progress - no operations are permitted
there are two services running in the services.msc from oracle so i don’ tknow what else to try… any idea?

win7 64 bits of course

I suspect that you need to configure SQL Developer.

maclochlainn

ow, seems strange to me because i didn t need to do that with the version 10 and I just want to do the same thingthan with tthe version 10: make my exercises about database.
I will try to do what you said.

Let me know it fixes the problem.

okay i’ve tried, the installation of sql developer works great. the web interface doesn t work. i vre tried to connect with the sql line command: error ORA-01034 : oracle not available + ORA-27101 : shared memory realm does not exist

if I try to conenct with sql developer I have : Status : Failure -Test failed: Listener refused the connection with the following error:
ORA-12505 TNS:listener does NOT currently know OF SID given IN CONNECT descriptor
charles

7 Oct 12 at 10:59 am
is that normal that i can’t have access to the web interface of the express application?

charles

7 Oct 12 at 11:01 am
The sqlplus command-line error generally means that the instance isn’t running. You can connect using the operating system credential by opening a command shell and running the following command:
sqlplus / AS SYSDBA
After you connect, you can start the instance with the following command in SQL*Plus:
startup
The ORA-01034 error typically occurs because laptops go into hibernation and Oracle expects the natural uninterrupted up-time of a server. The ORA-12505 error occurs when the listener isn’t running. Hope this helps.
maclochlainn

7 Oct 12 at 11:49 pm
You may want to check this old APEX 4.0 instance.

man, i’m lost…. Where do I have to enter that? what s the problem in fact? the database cannot start ?

charles

8 Oct 12 at 7:51 am
It’s expanded to qualify where you type the command. As to what the problem is in your case, all that I can do is tell you generally what may cause the problem. After you try to restart the instance, let me know what happens.

maclochlainn

8 Oct 12 at 6:51 pm
sorry if I seem a bit stressed. It’s exhausting my intellectual ressources :p
Can we start again ? so I ve installed the express application then try the resolution then installed the sql developper program. But I wanted just to trun the express application like I did with the 10g version (who worked perfectly at the time).

My toughts about the problem was that the database cannot run and so the express application too… but I may be wrong… (it was based on the experience of others who hasn’t need the sql developper.
Am I right?
But If I understand correctly what you said, I have to create a link between the sql developper and the database of the express application?

HI,
I have installed oracle 11g express edition on windows 7 64 bit.I got the KEY error during installation but i ignored it. The product got installed.It worked well for couple of days. But Now i am getting the error:
Oops! Google Chrome could not connect to 127.0.0.1:8080
.
I have started all the oracle realted service.when i am trying to connect through SQL command line it gives TNS ORA 12154 error.

please provide the solution. as i need the data stored in the database. I have all forum but the solution did not work for me.

thanks

11 Oct 12 at 8:53 am
I can’t say whether you’re right or not. I’ve got a few questions.

Assumptions: You’re upgrading from Oracle 10g XE to 11g XE. You are installing a fresh sample database. You need to connect to the APEX account. If any assumption is wrong, let me know.

Questions:

- Did the database install correctly?
- Can you connect as the SYSTEM user to the database using the command-line SQL*Plus interface?
- You can’t connect to the APEX instance, and need instructions to troubleshoot the APEX installation?

Thanks,
Michael

maclochlainn

11 Oct 12 at 11:50 pm
Ritesh, You can’t get to the APEX engine, right? Can you connect as the SYSTEM user from the command-line SQL*Plus environment?

maclochlainn

11 Oct 12 at 11:51 pm
Since you have data in the database, I assume that while you reinstalled the database you never deleted the database files. Is that correct?

If so, the same incongruity exists in the data files that was obstructing your APEX connection. Question, …. is the data you have in the database inside the APEX development workspace or some other database?

maclochlainn

11 Oct 12 at 11:54 pm
1)nI m not upgrading from 10g to 11g. i m installing fresh 11g.

2) During first time the installation did not finish complete but closed the installation and oracle was working fine.but after two days it stopped working giving the error.

3) I re-installed it using info in your blog with the key changes & installation finished well.But i m not able to connect to http://127.0.0.1:8080/apex/f?p=4950 giving error “This webpage is not available
The connection to 127.0.0.1 was interrupted.”

4)I m not able to connect through SQL commmand line giving error “ORA-12154: TNS could not reslove the content indentifier specfied”

5) since i have deleted all the previous oracle contents i have lost the data. Also the content was in the apex development workspace.

Thanks

ritesh bajaj

13 Oct 12 at 1:31 am
is it because i have used symbol “@” in my password. I have read this in one of the Oracle forum.

ritesh bajaj

13 Oct 12 at 2:25 am
That certainly explains it.

maclochlainn

13 Oct 12 at 10:18 am
what does this means??????

if “@” symbol is the problem then How do i change the password for SYS user through SQL command Line.??

thanks

ritesh bajaj

14 Oct 12 at 2:05 am
You should be able to sign on with the operating credentials, like this from a command line shell (DOS):
sqlplus / AS sysdba
At the SQL prompt type these two commands with a conforming password (starting with a letter and using letters, numbers, or underscores):
SQL> ALTER USER SYS IDENTIFIED BY password; SQL> ALTER USER SYSTEM IDENTIFIED BY password;
It likely means none of the APEX configuration occurred.
maclochlainn

14 Oct 12 at 8:53 am
thanks , i now been able to connect through sql command line.

But i m not able to connect to http://127.0.0.1:8080/apex/f?p=4950 giving error “This webpage is not available
The connection to 127.0.0.1 was interrupted.”

Is this because port 8080 is not listening?
Also my computer Ip keeps on changing.

thks

ritesh bajaj

14 Oct 12 at 12:08 pm
This is just a guess but the lack of a correct password probably means it wasn’t configured correctly during the installation. The choices are troubleshooting it, or re-installing since you know the problem. I’m inclined toward the latter as the best course for you.

maclochlainn

14 Oct 12 at 1:48 pm
I have re-installed it with a simple password.

But again i m not able to connect to http://127.0.0.1:8080/apex/f?p=4950 giving error “This webpage is not available
The connection to 127.0.0.1 was interrupted.”

I have been trying all of the different combinations without success. I am installing 11.2 on a Windows 7 64 system. I have tried the regedit approach as well as renaming the file approach prior to advancing the install. However it never appears that my system never recognizes the tnslistener for XE.

Here is the output of my status:

Note the second line did not exist prior to trying to problem solve this issue.

Here is my listener.ora file:

Did you use the tnsping utility?
tnsping xe
Is the hostname uppercase? You can find it by running the following command.
hostname
If so, try changing the host file by including the hostname before the qualified hostname:
127.0.0.1 BUTASHI BUTASH1.americas.hpqcorp.net
If all that works, please shutdown the database and listener; and try validating the 8080 port with a Perl socket. This validates that there’s not something interfering with the communication.

You can also
XE = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = xe.localdomain) ) )
maclochlainn

16 Oct 12 at 10:37 pm
Thank you so much…the changes you recommended worked.

It was the entry in the tnsnames file, the final recommendation that ended up doing the trick. But I followed the other steps as well so it might have been both the host entry as well as the change to the tnsnames file.

Thanks again!!!

The whole thing failed on Win-64 because of a missing key. Shame on Oracle (what a joke).

Hi! I’m trying to install the Oracle Database Express Edition 11g Release 2 on a Windows 7 64x following the instructions above, but the page http://127.0.0.1:8080/apex/f?p=4950 isn’t showing, so I tried reinstalling, but without success. I tried to install following the maclochlainn method, and after I tried the Eder method, but both installations didn’t work for me.
Maybe it’s because I’m trying to install the Release 2 edition… any idea of how can make it work?

Milene

10 Dec 12 at 6:03 am
Milene,

You need to provide more detail about the failure. Also, during a re-install make sure you uninstall the software using the Add/Remove Programs option; and that you manually remove files that aren’t cleaned up by Windows Add/Remove Program option.

Ideally, you should make a registry copy before the install and restore the pre-install registry. Oracle doesn’t uninstall all registry keys.

maclochlainn

10 Dec 12 at 5:59 pm
Thanks for the reply! =]

Well, I’m removing the software by the CCleaner, and after there are some empty folders that keep existing in the C:\oraclexe folder that I manually remove.

I don’t know how to make a registry copy before the install, how can I do that?
But, after all the install/remove I did, the registry is lost, right? Now I just can recover it if i reinstall the Windows operational system?
If so, I have a problem, cause it’s the company pc and I can’t reinstall the Windows operation system by myself.

More info about the failure, let’s see, I unzip the DISK1 to my desktop and run the setup.exe.
I make the installation using the default location, and as I am using the Windows 7 64x that pop up error of “The installer is unable to instantiate the file…” does appear during the installation.
When it happens I do all the registry change things, like you said above, I open the regedit, go to HKEY_CLASSES_ROOT -> Installer -> Products -> 266B7A503A089BE4EAD1986A429434C1 -> SorceList -> Media and change the “1″ value data to C:\Users\mtoda\AppData\Local\Temp\{EF28066A-F707-4A2F-8913-B24DF3A067D1} and then I proceed the installation clicking on OK on the pop up. So the installation finishes with success.
But, when I try to open the Get Start page (http://127.0.0.1:8080/apex/f?p=4950), it just open a page with “Oops! Google Chrome could not connect to 127.0.0.1:8080″. So, idk what I’m missing…

One more thing, when I run the “Start database” appears the message:
The OracleServiceXE service is starting.
The OracleServiceXE service was started successfully.

And if I run the “Stop Database” appears the message:
net stop OracleServiceXE
The OracleServiceXE service is stopping.
The OracleServiceXE service was stopped successfully.

So I think maybe the database is working, but can the database work even if that Get Start page doesn’t?

Well, I think that’s it.

Milene

11 Dec 12 at 9:46 am
It sounds like the database installed correctly, and is working. The problem appears to be APEX from your description but could you check a couple things to make sure. Open a command shell and run this command with the password you created during the installation:
sqlplus system/your_password
Then, run this one with the TNS network alias:
sqlplus system/your_password@xe
If the first succeeded but second failed, please run this command:
tnsping xe
If that fails, please install Perl and test the viability of socket communication by using the sample files in this Perl socket example. Let me know what worked and didn’t work.
maclochlainn

11 Dec 12 at 11:00 am
Hi! I followed the instructions as follow:
I opened a cmd and typed sqlplus system/my_password, but it showed a message:
'sqlpus' is not recognized as an internal or external command, operable program or batch file
I don’t know what is TNS network alias, so I didn’t run the second command.

So, I installed Perl and tested the socket communication using those socket examples and it worked. The “Hello there!” message showed up.

What else can I do now?
Milene

14 Dec 12 at 3:15 am
Thanks for the solution. It worked. But I have so far successfully installed oracle server,but when I run the command:
C:\oraclexe\app\oracle\product\11.2.0\server\bin> lsnrctl status
I get ‘gt’ is not recognized as internal or external command operable program and batch file.

I have to confirm that Is there anything I might have escaped, might cause an error in futue in further progress.
Ruba

15 Dec 12 at 7:54 am
If the command was copied from the web, it’s possible that the “gt” code be a substitution for the greater than symbol. Is that possible?

maclochlainn

15 Dec 12 at 10:22 am
The sqlplus executable isn’t found, which means Oracle didn’t install or at least it failed to configure your system %PATH% variable. Please search for the sqlplus.exe in your operating system to see if it’s installed.

The TNS network alias is the short string that let’s you navigate levels 5, 6, and 7 of the OSI stack using Oracle’s Transparent Network Substrate (TNS).

maclochlainn

17 Dec 12 at 1:40 pm
The sqlplus.exe is in the path C:\Oracle\rcuHome\BIN.

Milene

18 Dec 12 at 4:53 am
Try running this command:
C:\Oracle\rcuHome\BIN\sqlplus system/your_password
Then, if that works repeat with this if it’s the TNS alias in your tnsnames.ora file.
C:\Oracle\rcuHome\BIN\sqlplus system/your_password@orcl
maclochlainn

19 Dec 12 at 11:49 pm
I run the command: C:\Oracle\rcuHome\BIN\sqlplus system/your_password

And I got this message: “Error 6 initializing SQL*Plus
Message file sp1.msb not found
SP2-0750: You may need to set ORACLE_HOME to your Oracle software directory”

So I searched how to solve this problem, and I tried to set the %ORACLE_HOME% variable. When I tried to run the first command again a pop up showed up with the message:
Message file UTILITY_MSG\spw.msb not found!
So, I think the varisble is still incorrect.
Milene

20 Dec 12 at 6:48 am

Milene, It’s possible that the %ORACLE_HOME%, %ORACLE_SID%, or %ORACLE_UNQNAME% are incorrect. The error means that the executable wanted to throw and exception but couldn’t find the file that contains error message in your installed language.

It’s best to set these in a batch file, oraenv.bat, like this:

REM SET Oracle Environment VARIABLES manually.
SET ORACLE_HOSTNAME=localhost
SET ORACLE_HOME=C:\Oracle\rcuHome
SET ORACLE_SID=orcl
SET ORACLE_UNQNAME=orcl
 
REM ADD Oracle's binary path to system path.
SET PATH=%ORACLE_HOME%\bin;%PATH%

Then, retry the post. That rules out whether or not it’s environment path items. Although, it does appear you have an incomplete installation.

Avinash, The registry error differs from install to install, which means you have to capture and repair the key value pair affected by your installation.

maclochlainn, thanks for the help.

I couldn’t complete the installation because I’m not working anymore at the corporation. But I passed your blog to the project team so they can continue the work.

I’m sorry for any inconvenience and thanks again.

This worked for me by following the steps mentioned at the beginning of the post by Mclaugh.

- Installed XE 11g 32 bit on Windows 7 64 bit
- Got the same pop up KEY_XE error. Fixed by adding the value in regedit (- HKEY_CLASSES_ROOT\Installer\Products\266B7A503A089BE4EAD1986A429434C1\SourceList\Media).

added value to REG_SZ –> C:\Users\hostname\AppData\Local\Temp\{078E83D7-3FCC-4A72-903B-995C7CE44681}\

- Added local machine IP address in host file (C:\Windows\System32\drivers\etc\hosts)
- After installation, I was able to start DB from start menu (http://127.0.0.1:8080/apex/f?p=4950:1:1816303992624411)
- Tested DB connection using cmd SQLPLUS.
- Installed Oracle client
- Installed Toad
- Added TNS_ADMIN and ORACLE_HOME path in environment variable.

Hope this helps!

This failure means that the XDB Server didn’t get configured during the install. You can manually install it.

Hi!

After to do step by step all the solutions expones in the post, the error acceding to the url http://127.0.0.1:8080/apex/f?p=4950 still remained.

Finally, I solved the problem changing the ip “127.0.0.1″ by “localhost” in the url:

http://localhost:8080/apex/f?p=4950

I hope this help you!!

Did you configure your C:\Windows\System32\drivers\etc\host file before installing? You can check Step #4 from this post for the target values (you typically only need the first three with DHCP configurations), but it should be done before installation because it opt to use the hostname or IP address (some values stored in database tables).

hi maclochlainn,

I’m to re-intall again due I got an error tring to connect to XE listener althougt the ‘lsnrctl status’ command is ok. In addiction after reboot the appex url does not works. I have a static IP 192.168.1.129 in my computer. Which values suggest me in the host system file? my pc name is My-PC.

Is necessary copy the KEY_XE.reg fily to the temp installation directoty or just change the registry key?

Thanks!!

It depends how it fails, and you just have to adjust to the registry key that fails.
