Very strong Server with lots of memory.
A query runs that inserts 40K records takes 1 second when run from psql.
It takes 20 minutes!! And 100% CPU !! when called from a standalone JDBC program.
No other users are running !!!
The problematic query:
2013-01-02 15:00:38.008 ISTLOG: duration: 1207547.589 ms execute <unnamed>: insert into CMR_IOALOG_2 select * from
CMR_IOALOG_PRE where ORDERNO in (select ORDERNO from CMR_AJF_PRE) or ORDERNO=0
This is probably not going to get much response without more information.
1) Where are you running the psql query versus the JDBC one i.e local or
over network?
2) What is the JDBC program?
3) Is there anything else between the program and the database?
4) What version of the Postgres JDBC driver are you using?
5) What is the Java code that invokes the query?
