I have little knowledge of db2 administration, and I can't figure out how to find the pid of the process locking the tab tables.
With db2top (screen "U"), I have the following table:
Agent Application Application Object Lock Object Lock Lock Is Locked Tablespace Id(State) Name Status Name Mode Type Status Count Blocker By Name ------------ ------------ -------------- ------------------- -------- ---------- ---------- ----- ------- -------- ----------- 7060(l) xxxxxxxxxx Lock Waiting YYYY01.TABLEZZ IS Table Granted 1 No 7974 USERSPACE1 7060(l) xxxxxxxxxx Lock Waiting Internal Variation S Variation Granted 1 No 7974 - 7060(l) xxxxxxxxxx Lock Waiting YYYY01.TABLEZZ[0] NS [X] Row - - No 7974 USERSPACE1 7060(l) xxxxxxxxxx Lock Waiting Internal Plan S Plan Granted 1 No 7974 - 7974(l) xxxxxxxxxx Lock Waiting Internal Variation S Variation Granted 1 Yes 8080 - 7974(l) xxxxxxxxxx Lock Waiting YYYY01.TABLEZZ[0] X [U] Row - - Yes 8080 USERSPACE1 7974(l) xxxxxxxxxx Lock Waiting Internal Plan S Plan Granted 1 Yes 8080 - 7974(l) xxxxxxxxxx Lock Waiting YYYY01.TABLEZZ IX Table Granted 1 Yes 8080 USERSPACE1
I have figured out that Agent 7974 is the blocking one. I'ld like to kill it and fix/test the bug. How can I figure out the pid of agent 7974 so I can attach a gdb to it?
If all you want to do is kill the agent, you can do it with db2 force application (7974). The client process ID is shown in db2top on the session screen (press l). You can also use db2pd -db <your database> -agents app=7974
