hi I am using DB2 V9.5 but there is a IMPORT transaction that will
never be able to commit itself.
Its status is forever "Commit Active", and is taking 12% CPU, and not
waiting on any lock.

The transactions is set table to not logged initially, import all data, then
commit. It hangs on the last
"commit" command.


I did a db2pd -edu and saw it is running as follows:

EDU ID TID Kernel TID EDU Name
USR SYS
================================================== ==================================================
3086 3086 635527 db2agent (DB) 1
263.196480 2.164422

Then I saw from db2pd -agent that it is using process 287150,

ddress AppHandl [nod-index] AgentEDUID Priority Type State
ClientPid Userid ClientNm Rowsread Rowswrtn LkTmOt
0x078000000024ACC0 65594 [001-00058] 3086 0 Coord
Inst-Active 287150 user1 db2bp 345 0 NotSet


so I do a truss on it:

$ truss -p 287150
__semop(0, 0x0000000000000000, 0) (sleeping...)

so what is this semaphore about, and how could i fix it? thanks.

never mind, problem solved by doing a complete removal of all system IPC.
