ISSUE:
Login fails to /oamconsole (Even though username and password are correct).
ERROR OBSERVED:
Logs @ DOMAIN_HOME/servers/oam_server/oam_server-diagnostics.log
<<
oracle.security.idm.OperationFailureException: oracle.security.am.common.jndi.ldap.PoolingException [Root exception is oracle.ucp.UniversalConnectionPoolException: Invalid life cycle state. Check the status of the Universal Connection Pool]
>>
REASON:
- The problem is caused by the accumulation of UCP* files that are generated over time due to unclean shutdowns (kill -9 ) of either AdminServer or OAM_Server nodes (Admin, Managed) Universal Connection Pool.
- Each time the universal connection pool [re]starts one of the temp files is created as /tmp/UCP/*temp.
- The problem arises if the variable part of the file name is not random enough.
- In that case we are trying to initialize a new pool, but finding a file of same name which is taken to indicate this pool already exists.
- The created temp file is cleaned up at every (clean/normal) shutdown.
- When insufficient viable connections remain we recycle the connection pool.
- These temporary UCP* files are located in the tmp directory.
- In case of Solaris location is /var/tmp
SOLUTION:
1) Shutdown OAM server and Admin Server.
2) Delete the existing UCP* temp files from the location below(based on OS)
/tmp
/var/tmp
$ cd /var/tmp
$ rm -rf UCP*
3) Start Admin Server
4) Start OAM managed server.
5) Try accessing /oamconsole(it opens without any issues)
