I'm not a Java expert so please forgive me my ignorance. JDBC application
is facing very strange performance problems during connect. Every now and then
everything appears to be hung and then, 10 minutes later, users proceed
normally but with the elevated blood pressure and serious lack of patience.
I was told that JDBC has it's own connection pooling mechanism and that it
will start it's own dedicated server connection. It seems though that the
string "SRVR=DEDICATED" has been ignored and that users are acquiring a shared
server connection.
Does anybody in this group have any experience with JDBC and MTS? Version is
8.1.7.1, 64 bit on HP-UX 11 with OPS. Dispatchers are cross-registered with
listeners on all 4 nodes for load balancing purposes. I found surprisingly
little material on the Metalink. No network collisions, no retransmits, no
timeouts can be seen from netstat -i and netstat -s. The NIC is 1GB Ethernet
and I would be very surprised if approximately 100 users could kill it with a
JDBC application. They could use DBA as a human sacrifice, though.
