Home -> Community -> Mailing Lists -> Oracle-L -> Re: persistent connections vs. login/logout white papers anyone?
Hi Robert,
When I signed on at cybersurf the webserver (apache/perl/DBI) was handling 500 - 900 clients at any one time and the listener process took the most CPU as defined by top. The database server was pinned and everything was failing.
By adding mod-perl to the mix (for caching database connections only,
all
the code was still running as a normal cgi) the listener dropped to
usual
CPU levels and the machine went to about a 30% CPU utilization.
The one caveat is ensure that the webserver has a is fairly aggressive
about
shutting down idle connections or the database server will swap out the
server side process causing shorter but still annoying delays.
Also use dedicated servers as the MTS has problems dealing with long winded connections.
HTH
