J2EE instance server node problem

[mario_bisonti2]

Hallo.

I would like to have 4 server node in my portal instance 7.40

I am able to add up to 3 server node but if I add 4 or more server node, it happens that components go in failed status.

In the trace I read:
(Failed in component: dbpool, BC-JAS-TRH) Cannot create connection. Possible reasons: 1)Maximum allowed connections to DB or EIS is reached. You can apply CSN Note 719778 in order to check and resolve connection leaks. 2) Configuration to DB/EIS is wrong or DB/EIS is temporary unreachable. 3) Connections are not enough for current load.

I followed "1600085 - Dbpool of AS JAVA causing application related issues" so I set:

sysDS.maximumConnections=2500

sysDS.connectionLifetime=90

but I can't set

sysDS.maxTimeToWaitForConnection because it isn't for my release but I suspect that the problem is about it, so, what could I do?

The problem still remains.

Thanks a lot

Mario

The problem was about MaxUserTasks on MaxDB

Setting it to 300 solved the problem
