Application logs in Netweaver Administrator of EP 7.01.

[Former Member]

Dear All,

We have and Enterprise Portal 7.01 SP7 which was a Homogenous System Copy on HP Unix/Oracle 11g environment.

When we try to start or stop an Application from Netweaver Administrator of the portal, we get an error "500 Internal Server Error" .

The Java Server is up and running without any issue.

Could you please suggest a solution to this.

The initial exception that caused the request to fail, was:

com.sap.engine.frame.cluster.message.DestinationNotAvailableException: Participant 37,844,850 is not available.

Renu,

could you please check if instance ID "37,844,850" is part of your cluster.

It is possible that after the system copy, there is some mixture of old/new instance ID's.

In configtool you could see the instance ID's of all instances part of your cluster.

There the ID does not include the last 2 digits, so it should be something like "378448"

Thanks Ventsi.

The issue is resolved, it was indeed an issue with the Instance Id.

It seems that not all server nodes are running.

Do you have more than one server node?

as what markus said, you can check the java status via SIDadm:

> cdpro

> jcmon pf=<InstanceProfile>

Cheers,
