Re: Tomcat+MySQL. Intermitent DbcpException: Server configuration denies access to data source -> Now pool exhausted
Posted by Monica Ferrero <mo...@activehotels.com>.
Hello!
I got an answer in the mySQL list, that pointed out that my number of
connections 500, was a lot more than the normal value of 100. Changing that
solved the problem of the Server configuration error, but I've gone back to
getting java.sql.SQLException: DBCP could not obtain an idle db connection,
pool exhausted (whole exception follows).
I thought the configuration
<parameter>
<name>logAbandoned</name>
<value>true</value>
</parameter>
<parameter>
<name>removeAbandoned</name>
<value>true</value>
</parameter>
would free and log abandoned connections, but it doesn't seem to do it.
Anyway, I have checked over all my result sets, statements and connections
and I think they are all closed properly...
So I'm still a bit stuck here...
Some other person in the Commons list, suggested that there might be some
problems with the DBCP, could it be so?
Any other suggestions?
Any help really appreciated.
Monica
