DB20014: DB2 dir_cache parameter can cause the database access processes to hang
Issue
If you use DB2 V9.7fp10 and the directory cache (dir_cache) parameter is set to yes, which is the default, processes that access the database (for example create db, list db) can hang. The processes are waiting for the sqleDirCacheLatch latch.
The stack trace shows most of the agents are waiting for the SQLO_LT_SQLE_KRCB__sqleDirCacheLatch latch.
Resolution
Set DIR_CACHE to no ("DIR_CACHE=NO").
