Description:
============

Installing TRA 5.7.0 in a TIBCO_HOME having BusinessEvents 4.0 corrupts the ".tra" files under BE 4.0 installation.

Environment:
===========

   o TIBCO Runtime Agent 5.7.0
   o TIBCO BusinessEvents 4.0

Symptoms:
========

If you have an existing BusinessEvents 4.0 setup and then install TRA 5.7.0 in the same TIBCO_HOME, all the ".tra" files under BusinessEvents 4.0 installation are corrupted and become unusable. This results in BE engine startup failure.

Cause:
=====

traUpgradeManager invoked by the TRA 5.7.0 installer corrupts BE 4.0 ".tra" files if it has one or more environment variables without any values.

Resolution:
==========

1) Comment out or remove the environment variables for which you aren’t specifying values before installing TRA 5.7.0.
2) After TRA is installed, run traUpgradeManager –revert –path C:/tibco/be/4.0. This will restore the original .tra files.
Symptoms:

Cause:

TIBCO BusinessEvents 4.0 ".tra" files get corrupt if you install TRA 5.7.0 after installing BusinessEvents 4.0.
