Error 500 displayed in iManager Clustering

Environment

Novell iManager 2.7.4 and above
Novell Open Enterprise Server 11 (OES 11) Linux Support Pack 1
NetIQ eDirectory

Situation

After logging into iManager and going to the Clusters Roles and Tasks, the option to display information about "My Resources" is selected.  At this point, the request seems to hang and will eventually come back with an error stating,
 
Server Error!
The server encountered an internal error and was unable to complete your request.  Either the server is overloaded or there was an error in a CGI script.
Error 500

Resolution

The following should be verified:
  1. Ensure the user, logged into iManager, has sufficient rights to perform the operation in question.
  2. Ensure the user is lum enabled.  (ie. Use the command id <username> at the server's console.
  3. When logging into iManager, use the IP address of the Master IP Resource server in "Tree:" box/field.
  4. Verify the tomcat ports are open and listening.  eg.  netstat -nap | grep 9005 and possibly 9009.

If all of the above still do not help resolve the issue, perform the following:
  • login to a terminal session as root (or su to root)
  • stop the sfcb service (/etc/init.d/sfcb stop)
  • rename /etc/sfcb/sfcb.cfg to another file
  • edit the new file, making a change to it, and then save it
  • rename the new file back to /etc/sfcb/sfcb.cfg, ensuring root root is the owner & group, 
  • restart tomcat6 (/etc/init.d/tomcat6 start), and
  • start the sfcb service (/etc/init.d/sfcb start)
This will need to be done on each server in the cluster.

After logging back into iManager, the operation should now be successful. 
***Note:  This issue may also be seen with other services such as the following: CIFS, Storage Management, DFS, and NFS.
