HOW TO: Change Informatica Home Directory back to previous version Home Directory after Informatica major upgrade
Solution
Let us assume, the upgrade is done from version 10.1.1 to 10.4.
Previous version home directory ($INFA_HOME) is /edwu1/appl/edwuat/Informatica
Upgrade was done (current $INFA_HOME) to location /edwu1/appl/edwuat/Informatica_10.4

The requirement is to change the current $INFA_HOME again to /edwu1/appl/edwuat/Informatica

1st method
  • Rename "Informatica" directory containing 10.1.1 binaries to Directory "Informatica_10.1.1" then ask your system admin to create a symbolic link for Informatica_10.4 to Informatica, so that whenever you refer to "Informatica" it will refer to "Informatica_10.4".
  • No need to modify the existing script and environment variables pointing to the previous version 10.1.1 home directory.
2nd method
  • Shutdown domain
  • Rename Informatica to Informatica_10.1.1
  • Rename Informatica_10.4 to “Informatica”
  • Take back up of current nodemeta.xml
  • Run DefineGatewayNode command from $INFA_HOME/isp/bin to modify entries in nodemeta.xml
    Example of command:
    ./infasetup.sh DefineGatewayNode -kf $INFA_HOME/tomcat/conf/Default.keystore -kp key_password -ld <INFA_HOME>/isp/logs -rf <INFA_HOME>/isp/bin/nodeoptions.xml? -kd $INFA_HOME/isp/config/keys
    If above command did not work, then try below:
    ./infasetup.sh DefineGatewayNode -cs "jdbc:informatica:oracle://DB_HOST_NAME:DB_PORT;ServiceName=ORCL" -du db_usrname -dp password -dt Oracle -dn domain_name -kf $INFA_HOME/tomcat/conf/Default.keystore -kp key_password -ld <INFA_HOME>/isp/logs -rf <INFA_HOME>/isp/bin/nodeoptions.xml? -kd $INFA_HOME/isp/config/keys
    For details about options of command related to your environment, open designer -> help - Contents -> Search -> enter "updategatewaynode"
    Refer KB 341500​ for more details.
  • Start the node
  • Also, check-in AdminConsole for any environment variable or node backup is pointing to the previous location, modify them accordingly.​
3rd method
  • It is the longest method.
  • Take a backup of 10.4 domain database, repository database, nodemeta.xml, siteKey, and security keys (https key files, tls files)
  • Remove everything related to 10.1.1, 10.4
  • Restore 10.4 in the desired directory.
