Oracle Fusion Apps: BI Instance processes would not start and result in error

Issue

Run the following command to start the BI instance (after successfully starting all the Fusion Applications domains). But BI processes wouldn't start and will result in error.

Command: $FA_BASE/instance/BIInstance/bin/opmnctl startall

Error Output

Cause

After an in-depth analysis and investigation we found that the issue had come as a result of someone previously using "root" superuser to start the BI instance. As a result some of the file ownership were automatically updated to the "root" user.

Fix

Simply change the ownership to the fusion apps user (in our case the user name was "fusion") and give 755 permission to the following directories using chown and chmod commands respectively:

$FA_BASE/instance/BIInstance

Now simply try restarting the BI instance and it will be successfully started this time.

Environment
