Talend: Updating parameters after the configuration is finalized

It may happen that you will need to change the values of the configuration parameters when they have already been finalized in the Talend Administration Center. Unfortunately, this can not be done from the TAC level, but there is a solution that will allow you to unlock, but it requires editing the TAC configuration itself. We’re talking about the configuration.properties file that’s in the folder: <TalendAdministrationCenterInstallationDirectory> /apache-tomcat/webapps/org.talend.administrator/WEB-INF/classes

1. Stop the Talend Administration Center

Go to the folder where you have installed the TAC and there you will find two scripts: start_tac.sh and stop_tac.sh.

cd /home/talend/Talend-7.1.1/tac/

2. Open the configuration.properties file

Search for the following parameters and change to the given values. In the event that a parameter is marked with a comment sign, delete the comment and set the value:

cd /home/talend/Talend-7.1.1/tac/apache-tomcat/webapps/org.talend.administrator/WEB-INF/classes/
vim configuration.properties

Parameters and new values:


3. Save file

4. Restart the Administration Center

cd /home/talend/Talend-7.1.1/tac/

After a while, when the website is launched, log in to the TAC and change the configuration parameters to new ones. Once you are sure that everything is in order then you can re-finalize the configuration.
