UNABLE TO FORCE OFF APPLICATION THAT IS USING FMP CALLS | |
Produkt: | |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 | |
Problembeschreibung: | |
An application that is running a Stored procedure code via db2fmp process might not respond to a force command. Application status will be likely "PendingRemoteRequest" 1. db2pd -fmp output will show the agent being served by an FMP thread in the list of "Active Threads" Example: FMP Process: Address FmpPid Bit Flags ActiveThrd PooledThrd ForcedThrd Active IPCList 0x000000020095D9C0 32585 64 0x00000006 1 24 11 Yes 0x0000000200C3FB80 Active Threads: Address FmpPid EduPid ThreadId 0x00000002009CEFC0 32585 7843 1093683520 ... 2. Agent stack will show that the Agent is waiting on FMP - note the stack might be different but the key is that the agent is sqlccipcWaitSynch when it has called the sqlerInterruptThreadedFmp function.

There will be "nonEDu" stack files in the db2dump directory. Most of them will show the function sqlo_db2fmp_sigpre.
