Officially: No. Most ideas to this end have been a failure, because the low-priority query might hold locks that the high-priority query needs, so merely "nice"-ing the processes doesn't work, you also need some considerable lock manager wizardry. (If, on the other hand, your two queries don't contend for locks, because they don't access the same data, you can try the "nice" approach.) > I have seem some C functions that will nice a SELECT at the time its run, > but I am using JDBC from a servlet engine cluster.... Those functions would have to run on the server, so it shouldn't matter which interface your start them under. -- Peter Eisentraut [EMAIL PROTECTED] ---------------------------(end of broadcast)--------------------------- TIP 5: Have you checked our extensive FAQ? http://www.postgresql.org/users-lounge/docs/faq.html
