Problem(Abstract)
IBM Installation Manager is installed in nonadministrator mode. A super-user tries to start Installation Manager. Installation Manager is disabled and cannot be started by the nonadministrator user.
Symptom
A super-user starts an instance of Installation Manager that was installed by a nonadministrator user. Installation Manager fails with the errors:
CRIMCEB884626E ERROR: The Installation Manager cannot be started. The registry information does not exist or does not match with this executable. This may happen if you are trying to run Installation Manager installed
by another user.
00:03.02 ERROR [main] com.ibm.cic.agent.internal.application.
HeadlessApplication run
The Installation Manager cannot be started. The registry information does not exist or does not match with this executable. This may happen if you are trying to run Installation Manager installed by another user.
When the nonadministrator user starts Installation Manager, the following errors occur:
Invalid Configuration Location:
Locking is not possible in the directory "/InstallationManager/bin/eclipse/configuration/org.eclipse.osgi". A common reason is that the file system or Runtime Environment does not support file locking for that
location. Please choose a different location, or disable file locking passing "-Dosgi.locking=none" as a VM argument.
/InstallationManager/bin/eclipse/configuration
/org.eclipse.osgi/.manager/.file TableLock (EDC5111I Permission denied.)
Cause
When a super-user starts Installation Manager, the ownership of the following subdirectories in the /InstallationManager/bin/eclipse/configuration/ directory are changed to the super-user:org.eclipse.core.runtime
org.eclipse.equinox.app
org.eclipse.osg
As a result, the nonadministrator user cannot write files in these directories.
Resolving the problem
To resolve this issue:
1. Login as a super-user.
2. Run the command: cd /opt/eclipse/configuration
3. Change the ownership of the following directories to the nonadministrator user.
a. If Installation Manager is installed in nonadministrator mode, run the command:chown -Rh imadmin org.eclipse.core.runtime org.
eclipse.equinox.app org.eclipse.osgi
b. If Installation Manager is installed in group mode, run the command:chown -RH imadmin:imgroup org.eclipse.core.
runtime org.eclipse.equinox.app org.eclipse.osgi
4. chown -hR imadmin ./workspace
5. Login as the nonadministrator user.
6. Start Eclipse.
