In this case, only one user id failed to login into IBM Business Process Manager (BPM) Process Designer and the system prompted error in the screen dump. Even rebooting the BPM environment did not solve the problem.

CORBA MARSHAL 0x4942f89a No;nested exception is:
   org.omg.CORBA.MARSHAL: Unable to read value from underlying bridge:
Unable to read value from underlying bridge: ClassNotFoundException com.microsoft.sqlserver.jdbc.SQLServerException vmcid:IBM minor code:89A completed:No

 

From the BPM server log (systemOut.log), we found the error below:

Root cause analysis

IBM BPM database contains entries for groups that are imported from the user registry. If the capitalization of a group name is changed in the user registry, IBM BPM mistakenly tries to create an entry in the database the next time the server starts. This attempt fails with the following exception in the "Error/stacktrace for field (from the ffdc file) when SQL-SERVER is in use as database:

In the BPM server log (systemOut.log), you can see the message below about saving the user groups:

[9/25/17 20:18:56:122 CST] 00000034 wle_security  I com.lombardisoftware.server.core.GroupCore getAllGroupsInternal

Workaround

In the Process Admin Console, select IBM BPM Admin and then select ManageCaches. On the page that opens, click Reset to clear the GroupInfoCache and restart BPM.

 

Solution

APAR JR53171 was developed to make sure that group names are identified as equivalent if only the capitalization of their names differs. When the server starts, a group is not added to the database corresponding to the group whose name capitalization changed if the group name exists in the database in a different capitalization style.
