As a long time Oracle DBA and perl mangler I have refrained from joining
this conversation until now.
Connection caching is a configuration option in DBI, not a coding
requirement. For web servers it is a single line edit in startup.pl
import DBICache versus import DBI if I recall incorrectly.
NO CODE CHANGES REQUIRED
Now caching connections will require clean code. Code that was
acceptable on a short term connection
causes problems on long term connections. Cursors left open, virtual
connections not closed, etc
are non-issues using DBI but huge problems with DBICache
Applications doing heavy sql or batch work should not use DBICache. Just
from an administrative perspective.
Session less applications like web servers SHALL use it. And I use the
legal meaning for shall
I don't care what database is on the end of a DBI connection, I mangle
em all, poorly
YMMV
