Connection reset / ConnectionDeadSQLException

Marc OttoApr 8 2019 — edited Apr 9 2019

Hello,

I am running a ADF application on a standalone weblogic server version 12.1.3.

Occasionally the following error happens and the only way to recover is by restarting the server. I have tried enabling JDBC debug logging but it doesn't provide any additional information.

Received exception while creating connection for pool "DS1": IO Error: Connection reset.

java.sql.SQLRecoverableException: IO Error: Connection reset

Caused By: java.net.SocketException: Connection reset

weblogic.jdbc.extensions.ConnectionDeadSQLException: weblogic.common.resourcepool.ResourceDeadException: 0:weblogic.common.ResourceException: Could not create pool connection for datasource 'DS1'. The DBMS driver exception was: IO Error: Connection reset

As far as i understand this is related to network errors or DB problems, can it be weblogic causing this? The application have been running for years with the same data source configuration and only recently has the error started to occur. For this reason i do not expect the weblogic server or application to be the problem. Leaving me just with network and DB.

Is there any additional logging or debug steps i can use to find the exact problem?

side note: the urandom is already used on startup so should not be a random generator problem.

TIA
