Correct wrong data in IFCID0172 QW0172HQ/QW0172Q1 when package changes occur during waiting/deadlocking

See this idea on ideas.ibm.com

The issue is that

1.- Thread 1 and Thread 2 get locks

2.- Thread 1 changes packages

3.- Thread 1 and 2 deadlock

4.- Thread 1 is chosen as blocker and deadlock processing uses user data from Thread 1's waiter, but

the package dependent information is incorrect for the holder/blocker because Thread 1 changed

packages before waiting/deadlocking

 

Db2 and IRLM don’t currently have any sort of tracking for package changes that we could use to get

the correct information during deadlock, so the way we’ve decided is best to try and move forward is

to change Db2 lock requests to pass package information to IRLM and update IRLM structures to save

the info in case the lock becomes involved in deadlock. However, there are potential performance issues

with adding this tracking. 


In the meantime, customers should be able to use the stmtid to search the sysibm tables for most

of the package dependent information if the blocker used static SQL. We get the stmtid when the

lock is requested, so it will be accurate when the blocker is reported.
