Hi, There is nothing exactly like the database pool in JDBC. However, there are solutions for this problem.
The first thing you should do is run a reverse proxy in front of your mod_perl server. That typically reduces the number of mod_perl processes by a factor of 10, i.e. 1000 mod_perl processes for 10,000 front-end proxy processes. See http://perl.apache.org/docs/1.0/guide/strategy.html#Adding_a_Proxy_Server_in_http_Accelerator_Mode Note that there are many lightweight proxy servers now that can act as a front-end for mod_perl, not just Apache httpd. That's definitely what you should do first, but if you've done that and it's still not enough, you can also use DBD::Gofer. There is an explanation here: http://search.cpan.org/~timb/DBI-1.627/lib/DBD/Gofer.pm#Connection_Pooling_and_Throttling Tim's slides explaining how this was used in a real-world scenario are here: http://www.slideshare.net/Tim.Bunce/dbdgofer-200809 - Perrin On Thu, Jun 27, 2013 at 2:26 AM, xiaolan <practicalp...@gmail.com> wrote: > Hi, > > Currently I have been using Apache::DBI for long connections to Mysql. > But having the problem that, if the apache processes are 10000, they open > 10000 connections to mysql, this make the DB crashed. > Is there any software for modperl working like Java's JDBC for connection > pooling? > > Thanks. >
