Re: ora-4031 & large_pool

So you're telling me that MTS can magically be invoked somewhere in the outside world, without the database being configured for it? I don't think so.

At the time I sent the quoted message, I wasn't able to connect to the DB. I can now, and every session is DEDICATED. Which doesn't surprise me, since the DB is not configured for MTS.

And MTS were being used, the hourly samples would not show 16MB free memory in the large pool (out of 16M allocated). THEY ARE NOT USING MTS! Which is why the error is so frustrating.

Default values can well give you MTS. Default value for dispatchers is to start a disparcher for IPC and another one on localhost, port 1521.

The best thing is to check V$SESSION and statspack.
