AFAIK, the DEADLOCK TIMEOUT parameter is only for distributed transactions. Is this the case with your problem? If not, then one application or the other will receive an error if a deadlock occurs. I suspect in your instance that the programs are not experiencing deadlock problems, but some other cause, like the transactions are not being ended. >> >> The isolation level is set to repeated read, is that appropriate? That's pretty application specific, both in terms of the program design, and the non-query load on the engine. If you don't have performance problems repeatable reads, then by all means keep it. -- Bryan Tonnet batonnet@phase4.com.au
