RE: JDBC and MTS

[Jeffrey Beckstrom]

I recall an old bug where MTS would sleep for a bit - don't recall the bug anymore.   Jeffrey Beckstrom Database Administrator Greater Cleveland Regional Transit Authority 1240 W. 6th Street Cleveland, Ohio 44113 (216) 781-4204 >>> [EMAIL PROTECTED] 6/17/03 12:35:20 PM >>> b) I use server=dedicated, is srvr=dedicate a short hand version of it? -----Original Message----- Sent: Tuesday, June 17, 2003 8:25 AM To: Multiple recipients of list ORACLE-L OK. Let me get some things straight: a) I'm not a developer. I'm one of those vile creatures called DBAs.     I don't program. I troubleshoot other people's programs. Other people     program, I nag. When developers start writing bug-free software which    uses the database in the most optimal way, my job is gone. b) The whole problem is that even after specifying SRVR=DEDICATED in the     connect string, the darned thing still connects as an MTS connection. c) What was the issue that you faced? That was my original question.
