Oracle 12c Pre-requisites
Installing any Oracle database is tedious, but the installing the prerequisites can be especially tedious. This post tries to simplify the process by creating a single prereq.sh file for all the prerequisite libraries, except for the oracle-rdbms-server-12cR1-preinstall, which you should run after the prerequisite file.
The prerequisite file should contain the following:
yum install -y binutils \ compat-libstdc++-33 \ compat-libstdc++-33.i686 \ gcc \ gcc-c++ \ glibc \ glibc.i686 \ glibc-devel \ glibc-devel.i686 \ ksh \ libgcc \ libgcc.i686 \ libstdc++ \ libstdc++.i686 \ libstdc++-devel \ libstdc++-devel.i686 \ libaio \ libaio.i686 \ libaio-devel \ libaio-devel.i686 \ libXext \ libXext.i686 \ libXtst \ libXtst.i686 \ libX11 \ libX11.i686 \ libXau \ libXau.i686 \ libxcb \ libxcb.i686 \ libXi \ libXi.i686 \ make \ sysstat \ unixODBC \ unixODBC-devel \ zlib-devel \ zlib-devel.i686 |
You can run the prereq.sh script as the root user like you would source an environment file:
. ./prereq.sh |
Dependent upon what you installed when creating the Oracle Linux 7.1 operating system, you should see something like this in the output console:

After you have installed the prerequisites, you install the oracle-dbms-server-12cR1-preinstall library as the root user. You run the command as the root user like this:
yum install -y oracle-dbms-server-12cR1-preinstall |
You should see the following when it’s successful:

After running the oracle-dbms-server-12cR1-preinstall library, you can navigate through the Applications, Sundry, and Users and Groups to see the following dialog:
It’s hard to tell from the GUI the oracle user’s group. You can find oracle primary user’s group by checking the /etc/passwd file. You will find that oinstall is the primary user’s group.
As always, I hope this helps those trying to install an Oracle Database 12c instance. Please post a comment if you have a better way to load the pre-requisite packages.
Linux User-Group Console
This post shows you how to add the menu option and GUI to set users and groups. It’s quite a bit easier than mastering all the command-line syntax. It makes setting up the required user and group accounts for an Oracle Enterprise or MySQL database solution much easier.
You add the utility by calling the yum (Yellowdog Updater, Modified) utility like this:
yum installed -y system-config_users |

After successfully installing the radian, rarian-compat, system-config-users, and system-config-users-docs packages, you will find that there’s now a Users and Groups option when you navigate by clicking on Applications and then clicking on Sundry from the menu.
Menu Instructions
- You navigate to the Applications menu, and choose Sundry from the menu list and Users and Groups from the menu item to continue.
- You will be prompted for the sudoer’s password in this dialog.
- At this point, you can use the GUI interface to set users and groups.
As always, I hope this helps those trying to set users and passwords without mastering the command-line syntax.
Debug PL/SQL Web Pages
What happens when you can’t get a PL/SQL Web Toolkit to work because it only prints to a web page? That’s more tedious because any dbms_output.put_line command you embed only prints to a SQL*Plus session. The answer is quite simple, you create a test case and test it inside a SQL*Plus environment.
Here’s a sample web page that fails to run successfully …
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 | CREATE OR REPLACE PROCEDURE html_table_values ( name_array OWA_UTIL.VC_ARR , value_array OWA_UTIL.VC_ARR ) IS BEGIN /* Print debug to SQL*Plus session. */ FOR i IN 1..name_array.COUNT LOOP DBMS_OUTPUT.put_line('Value ['||name_array(i)||'='||value_array(i)||']'); END LOOP; /* Open HTML page with the PL/SQL toolkit. */ htp.print('<!DOCTYPE html>'); htp.htmlopen; htp.headopen; htp.htitle('Test'); htp.headclose; htp.bodyopen; htp.line; htp.print('Test'); htp.line; htp.bodyclose; htp.htmlclose; END; / |
You can test the program with the following anonymous block as the SYSTEM user, which is equivalent to the following URL:
http://localhost:8080/db/html_table_values?begin=1004&end=1012 |
The following test program lets you work:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | DECLARE x OWA_UTIL.VC_ARR; y OWA_UTIL.VC_ARR; BEGIN /* Insert first row element. */ x(1) := 'begin'; y(1) := '1004'; /* Insert second row element. */ x(2) := 'end'; y(2) := '1012'; /* Call the anonymous schema's web page. */ anonymous.html_table_values(x,y); END; / |
It should print:
Value [begin=1004] Value [end=1012] |
I hope this helps those looking for a solution.
SQL Developer & PL/SQL
While SQL Developer installs with a dbms_output view, some organizations close it before they distribute images or virtual machine (VM) instances. This post shows you how to re-enable the Dbms Output view for SQL Developer.
SQL Developer DBMS_OUTPUT Configuration
- You need to open SQL Developer, which may look like this when the
DBMS_OUTPUTview isn’t visible.
- You need to click on the View menu option in SQL Developer and choose the Dbms Output dropdown menu element.
- You should see a grayed-out Dbms Output view.
- You should type a simply “Hello World!” anonymous block program in PL/SQL, like the one shown in the drawing.
- After writing the “Hello World!” anonymous block program in PL/SQL, click the green arrow to start the statement and you will see two things. There is now a Script Output view between your console and Dbms Output views, and it should say “anonymous block completed.” Unfortunately, none of your output is displayed in the Dbms Output view because you need to enable it.
- If you hover over the Dbms Output view’s green arrow, you see the help message that describes the behavior of the green arrow. The Dbms Output green arrow lets you enable the Dbms Output view for output.
- After you click the Dbms Output view’s green arrow, you receive a Select Connection prompt for the view. Make sure you have the right user, and click the OK button to continue.
- After you create the connection for the Dbms Output stream, the view area becomes white rather than gray.
- Click the green arrow to start the statement and you will see the “Hello World!” string in the Dbms Output view.”
As always, I hope this helps those looking for a solution.
Using a Sparse Index
My vacation from my blog is officially over. The question that I’m answering today is: How can you pass a set of non-sequential ID values to a function and return a result set? You can solve the problem by passing an ADT (Attribute Data Type) or UDT (User Defined Type) variable into a subquery of a cursor. The subquery leverages the TABLE function to translate the ADT or UDT into SQL result set, which is equivalent to a comma-delimited list of values.
You can also solve this problem with Native Dynamic SQL (NDS). However, the person who posed the question didn’t want to use NDS to build out a variable length list of comma-delimited numbers.
You need to create three object types for this example. They are:
- a list of numbers
- a record structure, declared as an object type without methods
- a list of the record structure
These are the SQL commands to create the required data types:
CREATE OR REPLACE TYPE list_ids IS TABLE OF NUMBER; / |
CREATE OR REPLACE TYPE item_struct IS OBJECT ( item_id NUMBER , item_title VARCHAR2(80) , release_date DATE ); / |
CREATE OR REPLACE TYPE item_struct_list IS TABLE OF item_struct; / |
Next, you create a nonsynchronous function. It takes a sparsely populated list of values that map to the surrogate key of the column, which is typically the table’s primary key column. It returns a collection of the item_struct object type. This type of function is an object-table function.
The code follows:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 | CREATE OR REPLACE FUNCTION nonsynchronous ( pv_list_ids LIST_IDS ) RETURN item_struct_list IS /* Declare a record data structure list. */ lv_struct_list ITEM_STRUCT_LIST := item_struct_list(); /* Declare a sparsely indexed list of film items. */ CURSOR get_items ( cv_list_ids LIST_IDS ) IS SELECT item_id AS item_id , item_title || CASE WHEN item_subtitle IS NOT NULL THEN ': '|| item_subtitle END AS item_title , release_date AS release_date FROM item WHERE item_id IN (SELECT * FROM TABLE(cv_list_ids)) ORDER BY item_id; BEGIN /* Lood through the sparsely populated list of numbers. */ FOR i IN get_items(pv_list_ids) LOOP lv_struct_list.EXTEND; lv_struct_list(lv_struct_list.COUNT) := item_struct( item_id => i.item_id , item_title => i.item_title , release_date => i.release_date ); END LOOP; /* Return the record structure list. */ RETURN lv_struct_list; END; / |
The foregoing nonsynchronous function uses a nested query that transforms to a result set on lines 18 and 19. In the execution block of the program, it uses a call to the item_struct structure to capture and assign row values to an element of the lv_struct_list variable.
You can now test the nonsynchronous function with the following query:
COL item_id FORMAT 9999 HEADING "Item|ID #" COL item_title FORMAT A40 HEADING "Item Title" COL release_date FORMAT A11 HEADING "Release|Date" SELECT * FROM TABLE(nonsynchronous(list_ids(1002, 1013, 1007))); |
The query returns the record set as an ordered list in the result set, like:
Item Release ID # Item Title Date ----- ---------------------------------------- ----------- 1002 Star Wars I: Phantom Menace 04-MAY-99 1007 RoboCop 24-JUL-03 1013 The DaVinci Code 19-MAY-06 |
I hope this answers the question about how to get results sets with sparsely populated ID values.
REGEXP_LIKE Behavior
Often, the biggest problem with regular expressions is that those who use them sometimes don’t use them correctly. A great example occurs in the Oracle Database with the REGEXP_LIKE function. For example, some developer use the following to validate whether a string is a number but it only validates whether the first character is a number.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | DECLARE lv_input VARCHAR2(100); BEGIN /* Assign input value. */ lv_input := '&input'; /* Check for numeric string. */ IF REGEXP_LIKE(lv_input,'[[:digit:]]') THEN dbms_output.put_line('It''s a number.'); ELSE dbms_output.put_line('It''s a string.'); END IF; END; / |
When they test numbers it appears to works, it even appears to work when the test string start with number, but it fails with any string that starts with a character. That’s because the REGEXP_LIKE function on line 8 only checks the first character, but the following checks all the characters in the string.
8 | IF REGEXP_LIKE(lv_inputs(i),'[[:digit:]]{'||LENGTH(lv_inputs(i))||'}') THEN |
You can also fix it with the following non-Posix solution:
8 | IF REGEXP_LIKE(lv_input,'[[0-9]]') THEN |
You can add a collection to the program and use it to test single-digit, double-digit, and string with a leading integer. Save the program as test.sql and you can test three conditions with one call.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 | DECLARE /* Declare the local collection type. */ TYPE inputs IS TABLE OF VARCHAR2(100); /* Declare a local variable of the collection type. */ lv_inputs INPUTS; BEGIN /* Assign the inputs to the collection variable. */ lv_inputs := inputs('&1','&2','&3'); /* Read through the collection and print whether it's an number or string. */ FOR i IN 1..lv_inputs.COUNT LOOP IF REGEXP_LIKE(lv_inputs(i),'[[:digit:]]{'||LENGTH(lv_inputs(i))||',}') THEN dbms_output.put_line('It''s a number.'); ELSE dbms_output.put_line('It''s a string.'); END IF; END LOOP; END; / |
You can run the test.sql program like this:
SQL> @test.sql 1 12 1a |
It prints:
It's a number. It's a number. It's a string. |
As always, I hope this helps those looking for a solution.
SQL*Plus Tricks
Have you ever wondered how to leverage substitution variables in anonymous block programs? There are several tricks that you can use beyond passing numeric and string values to local variable. The generic default appears to take a number unless you cast it as a string but that’s not really the whole story. The first two are standard examples of how to use numeric and string substitution values.
The following accept a numeric substitution value:
1 2 3 4 5 6 7 8 9 10 | DECLARE lv_input NUMBER; BEGIN /* Assign substitution value to local variable. */ lv_input := &input; /* Print the local variable. */ dbms_output.put_line('['||lv_input||']'); END; / |
The following accept a string substitution value, casts the input as a string, assigns the string value to a 4,000 character length local variable, checks whether the 4,000 character length is greater than 10, and assigns the first 10 characters to the lv_parse_input variable:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | DECLARE lv_unparsed_input VARCHAR2(4000); lv_parsed_input VARCHAR2(10); BEGIN /* Assign substitution value to local variable. */ lv_unparsed_input := '&input'; /* Check size of input value. */ IF LENGTH(lv_unparsed_input) > 10 THEN lv_parsed_input := SUBSTR(lv_unparsed_input,1,10); END IF; /* Print the local variable. */ dbms_output.put_line('Print {lv_parsed_input}: ['||lv_parsed_input||']'); END; / |
Next, let’s examine two tricks. The first passes a case insensitive variable name and the second passes a case sensitive variable name as a parameter to an anonymous block program.
This declares an anonymous block program that uses a substitution value as a variable name:
1 2 3 4 5 6 7 | DECLARE mine VARCHAR2(10) := 'Default'; BEGIN /* Print the local variable's value. */ dbms_output.put_line('Print {mine} variable value: ['||&input||']'); END; / |
When you run the anonymous block, you’re prompted for an input variable. You provide a case insensitive variable name as the input value:
Enter value for input: MINE
old 5: dbms_output.put_line('['||&input||']');
new 5: dbms_output.put_line('['||MINE||']');
Print {mine} variable value: [Default] |
The downside of this approach, yields an ORA-06550 and PLS-00201 exception. Neither of these can be caught because Oracle raises the errors during parsing when the variable name isn’t a 100% case insensitive match. The same type of problem occurs in the next example when the input variable isn’t a 100% case sensitive match.
You can rewrite the program to handle case insensitive variables like this:
1 2 3 4 5 6 7 | DECLARE "Mine" VARCHAR2(10) := 'Default'; BEGIN /* Print the local variable's value. */ dbms_output.put_line('Print {mine} variable value: ['||"&input"||']'); END; / |
When you run the anonymous block, you’re prompted for an input variable. You provide a case sensitive variable name as the input value:
Enter value for input: Mine
old 5: dbms_output.put_line('['||&input||']');
new 5: dbms_output.put_line('['||"Mine"||']');
Print {Mine} variable value: [Default] |
Hope this helps those looking for a solution.
Using CALIBRATE_IO
Using Oracle’s Resource Manager requires you to understand the IO dynamics. The first step requires you to run the CALIBRATE_IO procedure from the DBMS_RESOURCE_MANAGER package.
Oracle provides some great examples about how to use the CALIBRATE_IO procedure of the DBMS_RESOURCE_MANAGER package in the Oracle Database Database PL/SQL Packages and Types Reference. The CALIBRATE_IO procedure returns the best answer when you provide a valid number of files, which you can capture by querying the V$ASM_DISK view.
The following code queries the view and assigns the value to a session level variable:
CLEAR BREAKS CLEAR COLUMNS CLEAR COMPUTES VARIABLE files NUMBER BEGIN SELECT COUNT(DISTINCT name) disks INTO :files FROM v$asm_disk; END; / |
When you have the number of files, you can calibrate the IO with the following anonymous block. The query should always work but just in case the NVL function on line 9 assigns the default number of files.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 | DECLARE lv_num_physical_disks BINARY_INTEGER; — v$asm_disk lv_max_latency BINARY_INTEGER := 10; lv_max_iops BINARY_INTEGER; lv_max_mbps BINARY_INTEGER; lv_actual_latency BINARY_INTEGER; BEGIN /* Assign actual files to anonymous block variable. */ lv_num_physical_disks := NVL(:files,2); /* Run the calibrate_io procedure. */ DBMS_RESOURCE_MANAGER.CALIBRATE_IO( num_physical_disks => lv_num_physical_disks , max_latency => lv_max_latency , max_iops => lv_max_iops , max_mbps => lv_max_mbps , actual_latency => lv_actual_latency); END; / |
You can query the results like this:
SELECT max_iops , max_mbps , max_pmbps , latency , num_physical_disks FROM dba_rsrc_io_calibrate; |
It should show results like these:
MAX_IOPS MAX_MBPS MAX_PMBPS LATENCY NUM_PHYSICAL_DISKS
-------- -------- --------- ------- ------------------

Hope this helps those using the CALIBRATE_IO procedure of the DBMS_RESOURCE_MANAGER package.

Use an object in a query?
Using an Oracle object type’s instance in a query is a powerful capability. Unfortunately, Oracle’s SQL syntax doesn’t make it immediately obvious how to do it. Most get far enough to put it in a runtime view (a subquery in the FROM clause), but then they get errors like this:
SELECT instance.get_type() * ERROR AT line 4: ORA-00904: "INSTANCE"."GET_TYPE": invalid identifier |
The problem is how Oracle treats runtime views, which appears to me as a casting error. Somewhat like the ORDER BY clause irregularity that I noted in July, the trick is complete versus incomplete syntax. The following query fails and generates the foregoing error:
1 2 3 4 | SELECT instance.get_type() AS object_type , instance.to_string() AS object_content FROM (SELECT dependent()AS instance FROM dual); |
If you add a table alias, or name, to the runtime view on line 4, it works fine:
1 2 3 4 | SELECT cte.instance.get_type() AS object_type , cte.instance.to_string() AS object_content FROM (SELECT dependent() AS instance FROM dual) cte; |
That is the trick. You use an alias for the query, which assigns the alias like a table reference. The reference lets you access instance methods in the scope of a query. Different columns in the query’s SELECT-list may return different results from different methods from the same instance of the object type.
You can also raise an exception if you forget the open and close parentheses for a method call to a UDT, which differs from how Oracle treats no argument functions and procedures. That type of error would look like this:
SELECT cte.instance.get_type AS object_type * ERROR AT line 1: ORA-00904: : invalid identifier |
It is an invalid identifier because there’s no public variable get_type, and a method is only found by using the parenthesis and a list of parameters where they’re required.
The object source code is visible by clicking on the expandable label below.
