Login to the Rational Change hangs on "Connecting" with "Failed to copy license library file to temp folder" in event.log

Technote (troubleshooting)


Problem(Abstract)

Attempts to login to IBM Rational Change hangs on "Connecting" and "Failed to copy license library file to temp folder" in event.log file after restarting server.

Symptom

The event.log will have an error similar to the following:


Connecting to Rational license server...
ERROR: Temp directory /tmp/8600_change/LicenseLibrary/1234567890123/32bit could not be created.
ERROR: Failed to copy license library file to temp folder.
Stack trace: java.io.IOException: No such file or directory
at java.io.File.createNewFile(File.java:894)

or

Connecting to Rational license server...
ERROR: Temp directory /tmp/8600_change/LicenseLibrary/1234567890123/64bit could not be created.
ERROR: Failed to copy license library file to temp folder.
Stack trace: java.io.IOException: No such file or directory
at java.io.File.createNewFile(File.java:894)

Cause

The problem is caused because the directory is missing or is not writable by the user used to start Rational Change. By default this should be user 'ccm_root'. This can happen if you start the server as user 'root' and then try to restart it some time later as user 'ccm_root'. The temporary directory is owned by 'root' and not writable by user 'ccm_root'

Environment

This is relevant to UNIX/Linux type operating systems.

Diagnosing the problem

  • Review the event.log for the error mentioned above

  • Check the permissions on the temp directory reference in the error.

Resolving the problem

To resolve the problem:

  1. Stop the Rational Change server

  2. Change the ownership of the affected files from user 'root' to user 'ccm_root'

  3. Restart Rational Change


Note: When you start Rational Change as user 'root' other files will be affected also. For example the event.log and pt.cfg. You should find all files owned by user ' root' in the Rational Change installation directory to get them all.
