My results with MTS were just great back in the 7.2+ days. But since the introduction of 8.x it's been very spotty. I've seen init.ora parameters for the dispatchers behave in ways I did not expect (set max_dispatchers to 30 and sure enough all 30 will start at db startup). I've seen shared servers crash the instance when the connection load raises above some "predefined" value (don't ask why, but one db will crash when the number of connections raises to 100, like clock work, while in dedicated server it carries on for 300 or more). I've called OWS many a time & have about 10 TARs all for the same basic problem (MTS Misbehaving). Is there a cure out there somewhere??? (HP-UX 10.20 & 11.0)

Well, it's been 3+ years since working on MTS, but it worked reliably on Oracle 7.2 at that time.

I would suspect a bug in the Linux release. Have you checked MetaLink for this?
