I have following experience , want to share with you:

DB2/MF CDC agent job died after print out following error in sysprint ,and router will keep report select failed error :

DB2LGIFI (1157): ; Issue START TRACE, rc = 16 ifi return code = 8 ifi reason code in hex = 00E60820
Issue START TRACE - seems as already active - continuing, rc = 16

After running following command in DB2


We are sure it is not a priviledge issue . above message is only a warning.
Finally we find the real reason in SYS LOG (console)

SYSTEM Error S047. A DB2 Load library added to Attunity SERVER JCL is not APF Authorized.
