Socket communication error

I have came across a socket communication error. This error is very general and can be caused by a number of issues.

In my case it related to a port conflict on the OBIEE server.

The first thing I would suggest to try would be stopping all OBIEE and MW services then using ps -ef | grep to kill any outstanding processes. Hopefully all goes well for you and upon restarting all services everything comes back up and all is well.

If you are still faced with issues I would try changing the port range that OBIEE uses this can be done through MW Enterprise Manager.

Head to BI > Core Application > Capacity Management > Scalability

Unlock & Edit settings and shorten the port range OBIEE is using, Apply the change and restart OPMN services.
