I know that DB2 LUW version 8 has "connection pooling" that provides a
connection concentrator (limits the number of simultaneous connections
that can occur). But does it really provide connection reuse in the
same manner provided by DB2 Connect or Websphere (or some 3rd party
connection interfaces)?
If DB2 V8 does have connection reuse, does the built-in DB2 connection
pooling require extra jdbc coding, and is it as robust as DB2 Connect?
I assume the DB2 V8 connection reuse would only run on the DB2 server,
and not on the application server (this is an issue if there are
multiple application servers).
I have a customer that is using a type 4 driver with a 3rd party tool
that provides connection pooling at the application server tier (there
are at least 4 different app servers), but it is not working well (it
maybe a jdbc type 4 driver problem, maybe a DB2 problem, or maybe a
problem with the 3rd party connection tool). It seems to me that maybe
DB2 Connect might provide a more compatible interface (at least they
can blame IBM if it does not work).
Any thoughts?
