[OO Tip] Changing the database (DB) username and/or password for Central & Scheduler


The need arises for the Database (DB) username and/or password to be changed within the Operations Orchestration (OO) application (namely Central and Scheduler) because of respective changes to the DB due to security implications.




NOTE: Windows variables such as %ICONCLUDE_HOME% in Linux are referred to by $ICONCLUDE_HOME. Paths in Windows use the "\" but in Linux they use the "/". The Linux scrpit is called "change-db-props.sh". The commands below need to be amended accordingly depending on the Operating System.

*** Changing the DB username/password for Central:

1. Open a command prompt

2. cd %ICONCLUDE_HOME%\Central\tools

3. change-db-props.bat new_username new_password

Output similar to the following should be observed:


 INFO [main] (11:25:14,530) com.iconclude.dharma.commons.security.DharmaEncrypterBase -         RSA/ECB/PKCS1PADDING
 INFO [main] (11:25:14,530) com.iconclude.dharma.commons.security.DharmaEncrypterBase -         PBEWITHSHA1ANDRC2_40
 INFO [main] (11:25:14,530) com.iconclude.dharma.commons.security.DharmaAESEncrypter - Instantiating AES encryptor...
 INFO [main] (11:25:14,686) com.iconclude.dharma.commons.security.DharmaBasicEncrypter - Instantiating DES encryptor...
 INFO [main] (11:25:14,686) com.iconclude.dharma.commons.security.DharmaBasicEncrypter - Instantiating DES encryptor...
 INFO [main] (11:25:14,686) com.iconclude.dharma.commons.security.DharmaAESEncrypter - Instantiating AES encryptor...

These mean the changes went through correctly.

Sometimes the following error is observed and the script exits:

log4j:WARN No appenders could be found for logger (com.iconclude.dharma.commons.security.DharmaEncrypterBase).
log4j:WARN Please initialize the log4j system properly.

To fix these the following should be done:

1. Edit change-db-props.bat (on Linux edit change-db-props.sh)

2. The SET ICONCLUDE_CLASSPATH line should have %ICONCLUDE_HOME%\jetty\resources; added at the end, semicolon included so it looks like:

SET ICONCLUDE_CLASSPATH=-classpath "%ICONCLUDE_HOME%\Central\tools\lib\secure-props.jar;%ICONCLUDE_HOME%\Central\WEB-INF\lib\dharma-commons.jar;%ICONCLUDE_HOME%\Central\WEB-INF\lib\commons-cli-1.0.jar;%ICONCLUDE_HOME%\Central\thirdparty\ant.jar;%ICONCLUDE_HOME%\Central\WEB-INF\lib\log4j-1.2.8.jar;%ICONCLUDE_HOME%\jetty\resources;"

3. On Linux, the variable is called "cp" and is set at line 66 of the script. Add :$ICONCLUDE_HOME/jetty/resources at the end (including the colon) so it looks like:


4. Save & exit.

5. Re-run the script.


*** Changing the DB username/password for Scheduler.

1. Open a command prompt.

2. Run the change-db-props.bat file to set up the environment.

3. Execute the following line (we use -d instead -u and -p because we are not changing the username/password directly, we are changing the properties referring to them):

"%ICONCLUDE_HOME%\jre1.6\bin\java" %ICONCLUDE_CLASSPATH% %ICONCLUDE_HOME_DEF% com.iconclude.dharma.tools.SecureProps -f %ICONCLUDE_HOME%\Scheduler\conf\secured.properties -d org.quartz.dataSource.schedulerDS.user=new_username -d org.quartz.dataSource.schedulerDS.password=new_password

On Linux first run:

1. . /installation/path/of/OO/.iconcluderc

e.g. . /opt/OO/Central-9.00/.iconcluderc

export cp="$ICONCLUDE_HOME/tools/secure-props.jar:$ICONCLUDE_HOME/Central/WEB-INF/lib/dharma-commons.jar:$ICONCLUDE_HOME/Central/WEB-INF/lib/commons-cli-1.0.jar:$ICONCLUDE_HOME/Central/thirdparty/ant.jar:$ICONCLUDE_HOME/Central/WEB-INF/lib/log4j-1.2.8.jar:$ICONCLUDE_HOME/jetty/resources"

"$ICONCLUDE_HOME/jre1.6/bin/java" -classpath $cp com.iconclude.dharma.tools.SecureProps -f $ICONCLUDE_HOME/Scheduler/conf/secured.properties -d org.quartz.dataSource.schedulerDS.user=new_username -d org.quartz.dataSource.schedulerDS.password=new_password

2. Restart Scheduler & Central.
