remote EJB call, CORBA COMM_FAILURE

[xca...@freemail.hu]

Hi,

There is a WAS v6.1 cluster running some EJBs. These EJBs are called from an other machine (running an other J2EE application server called BroadVision, so it is not a WebSphere AS). The EJB in WAS are called remotely using corba from the BV server. The applicatino in the BV server uses the websphere jar file to connect to WAS. During these remote EJB calles, sometime the following error can be seen in the BV logs. The problem occurs 5-6 times in an hour, while the BV system has about 500 active sessions.

What can be the problem here? It does not look like a resource problem the number of these problems is independent from the load on the system.

Hi, the error indicates a TCP/IP error could be causing the error.

http://publib.boulder.ibm.com/infocenter/javasdk/v6r0/index.jsp?topic=/com.ibm.java.doc.diagnostics.60/diag/appendixes/corba_minor_codes/corba_conn_purge_abort.html

I would do a couple of things:

1. make sure my NICs are functioning properly without errors
2. make sure you have the EJB container setup to handle the amount of requests coming in.
