XI -R/3 connectivity problem

[Former Member]

Hi All,

We are facing a problem with XI R/3 connectivity. The proxies(both inbound and outbound) is not working. When I call a outbound proxy it is catching the cx_ai_system_fault exception.

I know this is a BASIS issue, but I want to know where exactly to look into to solve this problem? What has caused the problem?

P.S The proxies were working correctly till last week. Now some thing has messed up.

Early responses are highly appreciated.

Thanks & Regards,

Jai Shankar.

Hi Jai,

Here is one solution from forum which was helpful for me when i was facing the same problem... See if it helps you...

Check the Queue, by double clicking the Queue id in the SXMB_MONI/SMQ2. Then try to execute the LUW of that. Probably, you can see this error in the Queue Monitor itself "JCO Failure.."..

If so go to SM59->

- Go to TCP/IP Connections-> AI_RUNTIME_JCOSERVER->double click

- Test the RFC destination. If connection is failure then it should be fixed. You may need to delete the entry and recreate the same . Still error may be required to restart the server.

If so, it may be because of Java Virtual Memory problem, no of parallel processes assigned in the Visual Admin..

Also have a look at these threads...

Regards,

Abhy

HI Abhy,

Thanks. In my case, nothing is available in queue, every thing seems to be ok from XI point. But there are no msg in SXMB_MONI of receiver R/3.

If I call an outbound proxy, the exception is getting raised.

Thanks & Regards,

Jai Shankar.
