Re: [Tomcat 5.5.17] Strange Problem With Batabase Connection Pool
Hi, (n+1)-th times !! : I've new information about the Database Connection Pool's mistery. After the last setup, adding testWhileIdle="true" and timeBetweenEvictionRunsMillis="240" it worked nice after about 3 hours of inactivity, but I don't undestand why It seems to work now and it didn't work before. Any ideas about what could be happening here?. Thanks in advance.

Hi for the n-th time ! : I've set up testWhileIdle="true" and timeBetweenEvictionRunsMillis="240". I'll try again in about an hour with this new setup and I'll come back if the new setup give me any new information. 2007/11/30, albert quinn <[EMAIL PROTECTED]>: > Hi again : > > I've read the URLs about DBCP configuration.

Re: [Tomcat 5.5.17] Strange Problem With Batabase Connection Pool
Hi again : I've read the URLs about DBCP configuration. Then, I've set up DBCP for my connection pool. I've added a validation query and I've set testOnBorrow="true". I've tried again and I've achieved the same strange behaviour : after about and hour of inactivity, it waits forever in the 3th line. No errors reported in the Tomcat logs. Any idea of what's happening or what can I do to know what's happening?. Thanks in advance. Albert 2007/11/29, albert quinn <[EMAIL PROTECTED]>: > Hi once more time : > > Thanks again for your help.

Re: [Tomcat 5.5.17] Strange Problem With Batabase Connection Pool
Hi once more time : Thanks again for your help. Sorry, I didn't know the connections aren't really closed. I've to leave now, but I'll read the URLs you gave me tomorrow and then, I'll try to set up DHCP properly. Thanks a lot. I'll come back if I get any kind of new information about the mistery.

When you call close() in your code that just returns the connection to the pool. The actual database connection remains open. The URL you want is: http://commons.apache.org/dbcp/configuration.html The starting point for DBCP is http://commons.apache.org/dbcp/ Mark - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: [Tomcat 5.5.17] Strange Problem With Batabase Connection Pool
Hi again, Mark : I've benn thinking about the problem and I don't really think it could be a problem with database connection timeout due to inactivity because when the web service is called, the web service gets a connection from the pool, it uses the connection, and then it closes the connection before returning the web service results. So, it mustn't be a problem with database connection timeout due to inactivity, don't you think? Thanks again for your help. 2007/11/29, albert quinn <[EMAIL PROTECTED]>: > It could be.

All of a sudden I have gotten several emails concerning tomcat. All I wanted to do was to get to petedge.

I'm really lost, and have no idea about what is happening. I forgot to tell that, when I call the web service after about an hour of inactivity and it waits forever at the 3th line, if i call the web service again, it works nice and it keeps on working nice (except if I wait about an hour again).

Could you database connection be timing out due to inactivity? It is worth adding a validation query to your DBCP configuration and setting testOnBorrow to true.
