RE: jdbc connction pool issues [EXTERNAL]
Yeah I didn’t consider that relevant at the time. All examples of creating a jdbc connection pool for SQL server on tomcat did not have specifying the factory in them. So I didn’t consider it relevant. My bad.

RE: jdbc connction pool issues [EXTERNAL]
Well the other tomcat servers had a custom factory specified. That was the only difference. (devs wrote their own library for it) So I looked in tomcat documentation and tried loading a out of the box factory that was available. That’s when it was picking up the maxActive setting and I started seeing that setting properly reflected in JMX.

No intitialSize is not defined. Im getting the data to verify from JMX, however we also have an APM called appdynamics loaded. Both verified the 8 max connections. Other tomcat servers with exact same jdbc connection pool config(only difference is servername, databasename, user and pass) show 50 max connections, which is what maxActive is set to.

RE: jdbc connction pool issues [EXTERNAL]
Hi Shawn, I can't speak to that monitoring tool or why it reports that way. I do see what you're saying though - I would expect the error message to be something like: >>name="jdbc/DataSource",type=DataSource has reached 80% limit. >>Current pool size [8, Max pool size [10] However, it could be that the number of maxActive connections at the time was 8 and they simply labeled it incorrectly. From my perspective it seemed that if you're getting an alert at 80% pool size and the current pool size is 8 then you're probably looking for a default setting of 10 somewhere that isn't being set and initialSize seemed like a good candidate for that setting. Perhaps you might check your monitoring tool thresholds - I would have to think that 80% is setting off bells and whistles so you have time to act before your JVM blows up.

If default is 10, they why would we be getting an error about 8 being max? Shawn Beard Sr. Systems Engineer | BTS Middleware Engineering | +1-515-564-2528 | sbe...@wrberkley.com<mailto:sbe...@wrberkley.com> -Original Message- From: Johnson, Jim Sent: Tuesday, December 15, 2020 1:35 PM To: Tomcat Users List Subject: RE: jdbc connction pool issues [EXTERNAL] ** CAUTION: External message Hi Shawn, I think you’re missing initialSize initialSize (int)The initial number of connections that are created when the pool is started. Default value is 10 maxActive (int) The maximum number of active connections that can be allocated from this pool at the same time. The default value is 100 It would make sense that 8 connections would be 80% utilized. I would try replacing maxActive with initialSize and seeing how that works for you.

Current pool size [8, Max pool size [8] Shouldn’t the max connections of the connection pool be 50 since maxActive is 50?
