Install cx_Oracle for Python

without comments

This shows you how to install the cx_Oracle library for Python 2.7 on Fedora Linux. If Fedora has it on the server you can download it with the following yum command:

yum install -y cx_Oracle-5.2.1-11g-py27-1.x86_64.rpm

Currently, you’ll get the following failure because it’s not available in the Fedora repository:

Error: Nothing to do

You can download the cx_Oracle library from the Python web site. The cx_Oracle documentation qualifies module interfaces, objects, and connections. Assuming your Linux user’s name is student, you download the cx_Oracle library into the /home/student/Downloads directory. Then, you use the su or sudo command to become the root user.

As the root user, run the following yum command:

yum install -y ~student/Downloads/cx_Oracle-5.2.1-11g-py27-1.x86_64.rpm

You should see the following output:

After you installed the software, you can test whether inside Python’s IDLE environment with the import command, like this:

Python 2.7.5 (default, Apr 10 2015, 08:09:05) 
[GCC 4.8.3 20140911 (Red Hat 4.8.3-7)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import cx_Oracle
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: libclntsh.so.11.1: cannot open shared object file: No such file or directory

This error indicates that Oracle Client software isn’t installed, which is true in this case. I only installed the Oracle Database 11g Express Edition. You need to download the Oracle Client software and install it as the root user.

You download the Oracle Client software from the Oracle web site. Assuming your Linux user’s name is student, you download the cx_Oracle library into the /home/student/Downloads directory. Then, you use the su or sudo command to become the root user.

As the root user, run the following yum command:

yum install -y ~student/Downloads/oracle-instantclient11.2-basic-11.2.0.4.0-1.x86_64.rpm

You should see the following output:

You can create a Python program that checks your ability to connect to the Oracle database, like the following oracleConnection.py file:

# Import the Oracle library.
import cx_Oracle
 
try:
  # Create a connection.
  db = cx_Oracle.connect("student/student@xe")
 
  # Print a message.
  print "Connected to the  Oracle " + db.version + " database."
 
except cx_Oracle.DatabaseError, e:
  error, = e.args
  print >> sys.stderr, "Oracle-Error-Code:", error.code
  print >> sys.stderr, "Oracle-Error-Message:", error.message
 
finally:
  # Close cursor. 
  db.close()

You can run this from the Linux command line with the following syntax:

python oracleConnection.py

It should return the following string:

Connected to the Oracle 11.2.0.2.0 database.

Now, you can create a Python program that reads data from the Oracle database. The following oracleString.py file reads a string literal from the pseudo table dual:

# Import the Oracle library.
import cx_Oracle
 
try:
  # Create a connection.
  db = cx_Oracle.connect("student/student@xe")
 
  # Create a cursor.
  cursor = db.cursor()
 
  # Execute a query.
  cursor.execute("SELECT 'Hello world!' FROM dual")
 
  # Read the contents of the cursor.
  for row in cursor:
    print (row[0]) 
 
except cx_Oracle.DatabaseError, e:
  error, = e.args
  print >> sys.stderr, "Oracle-Error-Code:", error.code
  print >> sys.stderr, "Oracle-Error-Message:", error.message
 
finally:
  # Close cursor and connection. 
  cursor.close()
  db.close()

You can run this from the Linux command line with the following syntax:

python oracleString.py

It should return the following string:

Hello world!

Now, you can create a Python program that reads actual table data from the Oracle database (assuming you have a copy of my video store database). The following oracleTable.py file reads a string literal from the pseudo table dual:

# Import the Oracle library.
import cx_Oracle
 
try:
  # Create a connection.
  db = cx_Oracle.connect("student/student@xe")
 
  # Create a cursor.
  cursor = db.cursor()
 
  # Execute a query.
  cursor.execute("SELECT item_title, item_subtitle FROM item")
 
  # Read the contents of the cursor.
  for row in cursor:
    print (row[0], row[1]) 
 
except cx_Oracle.DatabaseError, e:
  error, = e.args
  print >> sys.stderr, "Oracle-Error-Code:", error.code
  print >> sys.stderr, "Oracle-Error-Message:", error.message
 
finally:
  # Close cursor and connection. 
  cursor.close()
  db.close()

You can run this from the Linux command line with the following syntax:

python oracleTable.py

It should return the following strings (only a subset of the returned values):

("Harry Potter and the Sorcer's Stone", 'Two-Disc Special Edition')
('Harry Potter and the Chamber of Secrets', 'Two-Disc Special Edition')
('Harry Potter and the Prisoner of Azkaban', 'Two-Disc Special Edition')
('Harry Potter and the Chamber of Secrets', None)
('Harry Potter and the Goblet of Fire', 'Widescreen Edition')
('Harry Potter and the Goblet of Fire', 'Two-Disc Special Edition')
('Harry Potter and the Order of the Phoenix', 'Widescreen Edition')
('The Lord of the Rings - Fellowship of the Ring', 'Widescreen Edition')
('The Lord of the Rings - Fellowship of the Ring', 'Platinum Series Special Extended Edition')
('The Lord of the Rings - Two Towers', 'Widescreen Edition')
('The Lord of the Rings - Two Towers', 'Platinum Series Special Extended Edition')
('The Lord of the Rings - The Return of the King', 'Widescreen Edition')
('The Lord of the Rings - The Return of the King', 'Platinum Series Special Extended Edition')
('Star Wars - Episode I', 'The Phantom Menace')
('Star Wars - Episode II', 'Attack of the Clones')
('Star Wars - Episode III', 'Revenge of the Sith')
('Star Wars - Episode IV', 'A New Hope')
('Star Wars - Episode V', 'The Empire Strikes Back')
('Star Wars - Episode VI', 'Return of the Jedi')

As always, I hope this helps others who want to work with Python and the Oracle database.

Oracle Segment Fails

with 2 comments

The instance that I’ve built for my students in a Fedora VM is quite stable except for one feature. The feature is the hibernation process of the base operating system. Sometimes when the base operating system hibernates, it causes the Oracle shared memory segment to fail. When that happens you get the following error:

ERROR:
ORA-01034: ORACLE NOT available
ORA-27101: shared memory realm does NOT exist
Linux-x86_64 Error: 2: No such FILE OR DIRECTORY
Process ID: 0
SESSION ID: 0 Serial NUMBER: 0

I created the master sudoer account as the student user. The oracle user is configured so that you can’t log in to the Linux OS with it. To restart the instance you can do the following in a default Oracle 11g XE installation:

su - root

or, you can do this:

sudo sh

Then as the root user, you can sign on to the oracle user’s account by using the su command without a password, like:

su - oracle

As the user who installed the Oracle instance, you can connect to the database without a password after you source the environment file. The standard Oracle 11g XE environment file can be sources like this:

. /u01/app/oracle/product/11.2.0/xe/bin/oracle_env.sh

Alternatively, for my students there is a .bashrc file that they can manually source. It contains the following:

# Source global definitions
if [ -f /etc/bashrc ]; then
  . /etc/bashrc
fi
 
# Uncomment the following line if you don't like systemctl's auto-paging feature:
# export SYSTEMD_PAGER=
 
# User specific aliases and functions
. /u01/app/oracle/product/11.2.0/xe/bin/oracle_env.sh
 
# Wrap sqlplus with rlwrap to edit prior lines with the
# up, down, left and right keys.
sqlplus()
{
  if [ "$RLWRAP" = "0" ]; then
    sqlplus "$@"
  else
    rlwrap sqlplus "$@"
  fi
}
 
# Set vi as a command line editor.
set -o vi

You can source the oracle user’s .bashrc account, like this:

. .bashrc

After you’ve sourced the environment, you can connect as the internal user with the following syntax:

sqlplus / AS sysdba

Connected as the internal user, run these two commands in sequence:

shutdown IMMEDIATE
startup

Then, you should be able to connect as the student user or another ordinary user with the following syntax:

CONNECT student/student

Hope this helps my students and those who want to know how to restart the Oracle instance.

Can’t Display 256 Colors

without comments

If you’re reading this post, you most likely are trying to run the Oracle Database 11g or 12c runInstaller program, and it’s failing a critical dependency check and displaying an error like the one below. If so, choose n because if you choose y it won’t launch the Oracle Installer.

Starting Oracle Universal Installer...
 
Checking Temp space: must be greater than 500 MB.   Actual 30824 MB    Passed
Checking swap space: must be greater than 150 MB.   Actual 3967 MB    Passed
Checking monitor: must be configured to display at least 256 colors
    >>> Could not execute auto check for display colors using command /usr/bin/xdpyinfo. Check if the DISPLAY variable is set.    Failed <<<<
 
Some requirement checks failed. You must fulfill these requirements before
 
continuing with the installation,
 
Continue? (y/n) [n] n

The first thing to check is whether you’ve the $TERM environment variable. It’ll be set in your env list but may not be set in your .bashrc file. You can see whether it’s set by running the following command:

echo $TERM

It should return a value, like this:

xterm-256color

If you didn’t get that value, use the env command to lookup the $TERM. The correct value can be found by running the env command like this:

env | grep -i term

Add $TERM environment variable to your .bashrc file and source it after the change or reboot the user’s session:

export TERM=xterm-256color

If it still doesn’t work, some posts ask you to run xclock but you don’t generally install the xhost clients. Those articles assumes you’ve installed the xorg-x11-apps package library. That’s more or less a choice you made when installing the Linux OS. You can check for the presence of the library with the following command as the root user:

rpm -qa xorg-x11-apps

If the command fails to return a result from the search of Red Hat Package Manager (RPM) libraries, you haven’t installed it. You can install it as the root superuser with this syntax:

yum install -y xorg-x11-apps

It should display the following result when successful:

Oracle 12c Pre-requisites

without comments

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 \

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:

OracleUserCreated

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.

Fix VMware Networking

with 3 comments

Occasionally, my students loose their network connection when copying their virtual machines. This article shows you how to rebuild your Internet connection.

The first step requires you to identify the port number on your host operating system, which is typically Windows OS or Mac OS X. You can find that by running the following search from a Mac OS X Terminal session or Windows OS Command session.

If you’re on the Mac OS X, you launch a Terminal session and then use the sudo command to open a shell as the root super user, like this:

sudo sh

As the root super user on Mac OS X , you run the netstat command like this:

sh-3.2# netstat -a | grep 1.ntp | grep -v grep
udp4       0      0  192.168.147.1.ntp      *.*

VMware uses the same subdomain with one difference for the gateway, it uses node 2:

192.168.147.2

The alternate syntax to find Vmware’s subdomain requires you to use an Administrator account on Windows, like this:

C:\> netstat -a | findstr /C:.ntp

After you determine the subdomain, you need to ensure VMware is configured correctly. You navigate to the menu and choose Virtual Machine and then Settings from the dropdown menu. The software shows you the following:

Linux7Network1

Then, click on the Network Adapter under the Removable Devices, and you see the following screen:

Linux71Network2

You need to make sure that you’re using Internet Sharing, or Share with my Mac. If you’re not using it select it now.

Launch the hosted Linux OS and open a Terminal seesion. Inside the Terminal, you should find the machine’s address as the root address with the ifconfig utility. The technique follows:

[student@localhost ~]$ sudo sh
[sudo] password for student: 
sh-4.2# ifconfig
eno16777736: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        ether 00:0c:29:70:77:64  txqueuelen 1000  (Ethernet)
        RX packets 34  bytes 4190 (4.0 KiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
 
lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
        inet 127.0.0.1  netmask 255.0.0.0
        inet6 ::1  prefixlen 128  scopeid 0x10<host>
        loop  txqueuelen 0  (Local Loopback)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

Next, you need to edit some files, they assume the VMware Network Gateway is 192.168.147.2 and the machine’s address is “00:0c:29:70:77:64“. The first file you need to edit is the /etc/resolv.conf file, and it should look like this:

domain localdomain
search localdomain
nameserver 192.168.147.2

The second file you need to edit is the /etc/sysconfig/network file. It should look like this:

# Created by anaconda
NETWORKING=yes
HOSTNAME=localhost.localdomain
GATEWAY=192.168.147.2

The third file you need to edit is the /etc/sysconfig/network-scripts/ifcfg-eth0 file. It should look like this:

DEVICE=eth0
HWADDR=00:0c:29:70:77:64
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=dhcp
TYPE=Ethernet
DNS1=192.168.147.2
USERCTL=no
PEERDNS=yes
IPV6INIT=no

The last step requires that you reboot the machine or run the /etc/rc.d/init.d/network to restart the network. I hope this helps those trying to restore their VMware hosted operating systems network connection.

Fedora LAMP Steps

without comments

I posted earlier in the year how to configure a Fedora instance to test PHP code on a local VM. However, I’ve got a few questions on how to find those posts. Here’s a consolidation with links on those steps:

  1. Go to this blog post and install the httpd and php libraries with the yum installer.
  2. In the same blog post as step 1 (you can put the sample PHP code into the /var/www/html directory for testing), connect to the yum shell and remove the php-mysql library and then install the mysqlnd library.
  3. Go to this blog post and install the php-gd libraries, which enable you to render PNG images stored as binary streams in MySQL.

As always, I hope that helps.

It’s possible folks didn’t notice but Mac OS X no longer includes XQuartz by default from Maverick forward. You need to download XQuartz and install it. I’d recommend after you install Xcode.

Launch XQuartz and then either use the bash shell it opens or open a Terminal bash shell session. Inside the shell, you might start Secure Shell (ssh) like this:

Mac-Pro-3:~ michaelmclaughlin$ ssh student@192.168.2.170
student@192.168.2.170's password: 
Last login: Thu Jun  4 14:33:37 2015
[student@localhost ~]$ xclock &
[1] 10422
[student@localhost ~]$ Error: Can't open display:

Granted that’s a trivial error and running the xclock X11 applications isn’t crucial, an error that makes it more important is the following from Oracle’s old Designer/2000 application:

FRM-91111: Internal Error: window system startup failure.
FRM-10039: Unable to start up the Form Builder.

This is the desired behavior. Secure shell (ssh) can’t run it unless you make the connection with the -Y flag. You should use the following syntax:

Mac-Pro-3:~ michaelmclaughlin$ ssh -Y student@192.168.2.170
student@192.168.2.170's password: 
Last login: Tue Jun  9 14:56:55 2015 from 192.168.2.1
/usr/bin/xauth:  file /home/student/.Xauthority does not exist
[student@localhost ~]$ xclock &
[1] 10760

You can safely ignore the .Xauthority does not exist warning message because it’ll create a .Xauthority file and store the magic cookie after the warning message. You should see the xclock program running in the upper left hand corner of your console, like:

X11MacXclock

It’s terrific that you don’t get a font warning like you typically would using UTF-8 on Linux. Nice that the Mac OS fonts are so well done that there isn’t a raised exception.

Using xclock or xeyes isn’t very useful as a rule, but this method also lets you run any of the Linux GUI applications. For example, the following gedit command lets you run the gedit utility from a Mac OS console. If you’ve installed the gedit plug-ins, you also can use the Terminal console on the remote system.

X11GeditTerminal

The process sequence for the command-line is shown below:

1030     1  /usr/sbin/sshd -D     - The root process launches the ssh daemon
3145  1030  sshd: student [priv]  - The sshd launches a ssh session to manage a student ssh session
3152  3145  sshd: student@pts/1   - The ssh session launched to manage the ssh session
3166  3152  -bash                 - The bash shell launched by connecting through the ssh session
3240  3166  gedit                 - The gedit command issued inside a ssh session
3166  3240  gnome-pty-helper      - Launching the gedit session across X11 
3169  3240  /bin/bash             - Launching the Terminal session inside the gedit session across X11
3269  3884  ps -ef                - Command run inside the gedit Terminal session

Hope that helps those who want to use X11 applications on the Mac OS.

Fedora X11 Install

without comments

While working through getting my Mac OS X to work with X11, I stumbled on some interesting errors and misdirection solutions. Like most things, the solution was straightforward. Then, it struck me that I hadn’t installed it on my Fedora image. This blog post show you the errors I got the way to get it to work, and how to install X11 on Fedora.

The first step requires discovering the package. If you remember xclock or xeyes are X-Windows programs, it’s quite easy with this command (though it may take a moment or two to run):

repoquery -q -f */xclock

It will return something like this:

xorg-x11-apps-0:7.7-7.fc20.x86_64

You can then install X11 as a sudoer user with the yum utility like this:

sudo yum -y install xorg-x11-apps

It should return this to your console:

Loaded plugins: langpacks, refresh-packagekit

Complete!

After you install the xorg-x11-apps libraries, you can launch xclock. You should use the following syntax:

xclock &

It should display something like the following on your console:

X11xclock

The warning message is typically because you’re running something like en_US.UTF-8 mode. You can find suitable X11 character sets by using the following command:

sudo yum search xorg-x11-fonts

You can install all of them with the following command:

sudo yum -y install xorg-x11-fonts*

However, at the end of the day the warning doesn’t go way. You should just ignore it.

Hope this helps those who want to install X11 on Fedora.

Bash Arrays & Oracle

with 2 comments

Last week, I wrote about how to use bash arrays and the MySQL database to create unit and integration test scripts. While the MySQL example was nice for some users, there were some others who wanted me to show how to write bash shell scripts for Oracle unit and integration testing. That’s what this blog post does.

If you don’t know much about bash shell, you should start with the prior post to learn about bash arrays, if-statements, and for-loops. In this blog post I only cover how to implement a bash shell script that runs SQL scripts in silent mode and then queries the database in silent mode and writes the output to an external file.

I’ve copied the basic ERD for the example because of a request from a reader. In their opinion it makes cross referencing the two posts unnecessary.

LittleERDModel

To run the bash shell script, you’ll need the following SQL files, which you can see by clicking not he title below. There are several differences. For example, Oracle doesn’t support a DROP IF EXISTS syntax and requires you to write anonymous blocks in their PL/SQL language; and you must explicitly issue a QUIT; statement even when running in silent mode unlike MySQL, which implicitly issues an exit.

If you don’t have a sample test schema to use to test this script, you can create a sample schema with the following create_user.sql file. The file depends on the existence of a users and temp tablespace.

Click the link below to see the source code for a script that let’s you create a sample user account as the system user:

The following list_oracle.sh shell script expects to receive the username, password, and fully qualified path in that specific order. The script names are entered manually in the array because this should be a unit test script.

This is an insecure version of the list_oracle.sh script because you provide the password on the command line. It’s better to provide the password as you run the script.

# Define an array.

# Assign elements to an array.
cmd[0]="actor.sql"

cmd[2]="movie.sql"
 
# Call the array elements.
for i in ${cmd[*]}; do
  sqlplus -s ${username}/${password} @${directory}/${i} > /dev/null

# Connect and pipe the query result minus errors and warnings to the while loop.
sqlplus -s ${username}/${password} @${directory}/tables.sql 2>/dev/null |
 
# Read through the piped result until it's empty.
while IFS='\n' read actor_name; do
  echo $actor_name
done
 
# Connect and pipe the query result minus errors and warnings to the while loop.
sqlplus -s ${username}/${password} @${directory}/result.sql 2>/dev/null |
 
# Read through the piped result until it's empty.
while IFS='\n' read actor_name; do
  echo $actor_name
done

The IFS (Internal Field Separator) works with whitespace by default. The IFS on lines 29 and 37 sets the IFS to a line return ('\n'). That’s the trick to display the data, and you can read more about the IFS in this question and answer post.

You can run the shell script with the following syntax:

./list_oracle.sh sample sample /home/student/Code/bash/oracle > output.txt

You can then display the results from the output.txt file with the following command:

cat output.txt command:

It will display the following output:

User name: sample
Password:  sample
Directory: /home/student/Code/bash/oracle
 
Table Name
------------------------------
MOVIE
FILM
ACTOR
 
Actors in Films
----------------------------------------
Chris Hemsworth, Thor
Chris Hemsworth, Thor: The Dark World
Chris Pine, Star Trek
Chris Pine, Star Trek into Darkness
Chris Pratt, Guardians of the Galaxy

As always, I hope this helps those looking for a solution.

Bash Arrays & MySQL

without comments

Student questions are always interesting! They get me to think and to write. The question this time is: “How do I write a Bash Shell script to process multiple MySQL script files?” This post builds the following model (courtesy of MySQL Workbench) by using a bash shell script and MySQL script files, but there’s a disclaimer on this post. It shows both insecure and secure approaches and you should avoid the insecure ones.

LittleERDModel

It seems a quick refresher on how to use arrays in bash shell may be helpful. While it’s essential in a Linux environment, it’s seems not everyone masters the bash shell.

Especially, since I checked my Learning the Bash Shell (2nd Edition) and found a typo on how you handle arrays in the bash shell, and it’s a mistake that could hang newbies up (on page 161). Perhaps I should update my copy because I bought it in 1998. 😉 It was good then, and the new edition is probably better. The error is probably corrected in the current Learning the Bash Shell, but if not, the following examples show you how to use arrays in loops.

Naturally, these do presume some knowledge of working with bash shell, like the first line always is the same in any bash shell script. That you open an if-statement with an if and close it with a fi, and that you else-if is elif; and that a semicolon between a for-statement and the do statement is required when they’re on the same line because they’re two statements.

If you’re new to bash shell arrays, click on the link below to expand a brief tutorial. It takes you through three progressive examples of working with bash arrays.

Only one more trick needs to be qualified before our main MySQL examples. That trick is how you pass parameters to a bash shell script. For reference, this is the part that’s insecure because user command histories are available inside the Linux OS.

Here’s a hello_whom.sh script to demonstrates the concept of parameter passing:

1
2
3
4
5
6
7
8
9
10
#!/usr/bin/bash
 
# This says hello to the argument while managing no argument.
if [[ ${#} = 1 ]]; then
  echo 'The '${0}' program says: "Hello '${1}'!"'
elif [[ ${#} > 1 ]]; then
  echo 'The '${0}' program wants to know if you have more than one name?'
else
  echo 'The '${0}' program wants to know if you have a name?'
fi

If you need more on how parameters are passed and managed, you can check a prior blob post on Handling bash Parameters, or check the bash help pages. The following leverages bash arrays to run scripts and query the MySQL database from the command line.

You will need the three batch SQL files first, so here they are:

The following list_mysql.sh shell script expects to receive the username, password, database and fully qualified path in that specific order. The script names are entered manually because this should be a unit test script. Naturally, you can extend the script to manage those parameters but as mentioned I see this type of solution as a developer machine only script to simplify unit testing. Anything beyond that is risky!

# Read through the piped result until it's empty but format the title.
while IFS='\n' read actor_name; do
  if [[ ${actor_name} = "Actors in Films" ]]; then
    echo $actor_name
    echo "----------------------------------------"
  else
    echo $actor_name
  fi
done

The IFS (Internal Field Separator) works with whitespace by default. The IFS on lines 33 and 47 sets the IFS to a line return ('\n'). That’s the trick to display the data, and you can read more about the IFS in this question and answer post.

You can run this script with the following input parameters from the local directory where you deploy it. The a parameters are: (1) username, (2) password, (3) database, and (4) a fully qualified path to the SQL setup files.

./list_mysql.sh student student sampledb "/home/student/Code/bash/mysql"

With valid input values, the list_mysql.sh bash script generates the following output, which confirms inputs and verifies actions taken by the scripts with queries:

Username:   student
Password:   student
Database:   sampledb
Directory:  /home/student/Code/bash/mysql
 
Tables_in_sampledb
----------------------------------------
actor
film
movie
 
Actors in Films
----------------------------------------
Chris Hemsworth in Thor
Chris Hemsworth in Thor: The Dark World
Chris Pine in Star Trek
Chris Pine in Star Trek into Darkness
Chris Pine in Guardians of the Galaxy

If you forgot to provide the required inputs to the list_mysql.sh bash script, it alternatively returns the following output:

Username:  
Password:  
Database:  
Directory: 
 
./list_mysql.sh: line 25: /actor.sql: No such file or directory
./list_mysql.sh: line 25: /film.sql: No such file or directory
./list_mysql.sh: line 25: /movie.sql: No such file or directory

The secure way removes the password at a minimum! The refactored program will require you to manually enter the password for all elements of the array (three in this sample), and twice for the two queries. Here’s the refactored code:
