Environment:

TIBCO BusinessWorks ALL

Resolution:
==========
Scenario 1 : There are multiple JRE versions available in TIBCO_HOME, e.g., TRA 5.6.2 ships both JRE 1.5.0 and 1.6.0.

Approach: TRA provides a utility called traUpgradeManager under &ltTibco-Home>/tra/&ltversion>/bin. You can run traUpgradeManager as following to switch JAVA HOME from one to other. JRE related variables in bwengine.tra will be updated.

*******
traUpgradeManager -path C:/tibco/bw/5.6 -jre C:/tibco/jre/1.6.0
traUpgradeManager -path C:/tibco -jre C:/tibco/jre/1.6.0
*******

Scenario 2 : The target JRE version is not bundled with TRA but supported by the specific BW version.

Approach: Follow the instructions in the attached file tib_tra_replace-jre.pdf
and then use traUpgradeManager to update bwengine.tra.
