In the LOCKCONT screen you can put a "T" against an entry to see the SQL statement(if it is available).
The HELP for the LOCKCONT screen gives more info.
Here it is.
Starting with DB210,you may use the T line command to retrieve SQL information based on the statement ID in the trace record.
If the SQL is dynamic SQL, using the T line command will cause CA SYSVIEW for DB2 to display the performance information,
including the dynamic SQL statement text(DYNSQLTX IQL request),for the
selected statement if it is available in the cache.
If the SQL is static SQL, the T line command will cause CA SYSVIEW for DB2 to retrieve and display the SQL statement text
from the DB2 catalog.
