[TRAFODION-2688] Need a way to find queries that are stuck in compila…
…tion via RMS
When a query is stuck in compilation, the mxosrvr remains in connected
state forever.
Connection idle timer doesn't kick in. The query timeout can't cancel this
query
because the query hasn't start executing. There is a need to find the
process id of the
mxosrvr(master) process that is stuck in compilation via RMS. Then the
mxosrvr process can be killed.
To find the queries stuck in compile for more than 30 seconds
cd $TRAF_HOME/export/limited-support-tools/LSO
./offender -s queries_in_compile
This script lists queries that are being compiled for more than the given
number of seconds
