DB2 FOR LUW / DB2FORLUW / 970 - DB2

When an application is compiling SQL and enters a locking event 
such as a lock wait or lock timeout and that event is captured 
by a locking event monitor, the resultant PARTICIPANT_ACTIVITY 
record can contain invalid values for the statement operation, 
statement first use time and statement last use time. 
 
For example, consider this snippet of output from db2evmonfmt: 
 
Current Activities of Participant No 1 
---------------------------------------- 
Activity ID : 0 
Uow ID : 1459 
Package Name : SYSSH200 
Package Schema : NULLID 
Package Version : 
Package Token : SYSLVL01 
Package Sectno : 4 
Reopt value : none 
Incremental Bind : no 
Eff isolation : RR 
Eff degree : 0 
Eff locktimeout : -2 
Stmt first use : 1969-12-31-19.00.00.000000 
Stmt last use : 1969-12-31-19.00.00.000000 
Stmt unicode : no 
Stmt query ID : 0 
Stmt nesting level : 0 
Stmt invocation ID : 0 
Stmt source ID : 0 
Stmt pkgcache ID : 0 
Stmt type : Dynamic 
Stmt operation : DDL, Set Constraints 
Stmt text : SELECT c1 from t1 
 
 
In this particular case: 
- the Activity ID is correctly zero because the activity hasn't 
started yet (the SQL is compiling) 
- the Stmt first use and Stmt last use timestamps are zeros, 
which get converted into 1969-12-31-19.00.00.000000 
- the Stmt operation is "DDL, Set Constraints" rather than 
"Statement not prepared"
