JCO communication channel failure

[Bhargavakrishna]

Hi All,

we are facing an issue with JCO communication channel failure for synchronous scenario in moni.

Error when opening an RFC connection (CPIC-CALL: 'ThSAPOCMINIT' : cmRc=27 thRc=6 while testing the connection" AI_RUNTIME_JCOSERVER" in SM59.

PI Integration builder page is not opening, it is showing the timeout error " 500 connection time out "

i tried by restarting the server, no entries in SMQ1 and SMQ2. checked the RFC connection test for ECC and PI working fine.

PI is not picking any files all the interfaces are failed. it is not processing any messages all are failed with system error. all these are response messages with different message id's

please help me to resolve the issue.

Regards

Hi Bhargava,

Have you taken a look at below links:

http://scn.sap.com/thread/129282

http://scn.sap.com/message/1250585

One of the link says Try deleting  AI_RUNTIME_JCOSERVER and recreate it.

It might also be due to memory issues.

Cheers,

Ambrish

Basis team can resolve this issue. There is a communication failure between ABAP and Java Stack.

Hi

During this time what is the status in SAP MMC? JAVA stack started? Could you share you OS / DB?

Hi Bhargava,

Please check the exchange profile of PI server. It seems the connection to ESR is not working from exchange profile.

Hi Bhargava

1. Kindly check the T-code SM51 see the status of JAVA stack status?
2. T-code SM21 gateway communication & any other error log appearing?

Since you don't have authorization you may not check the MMC (SAP Management Console)

Hi Sriram,

Java stack status is active.

In sm21 error log " Operating system call receive failed"

Hi,

It seems issue with data base and os side. It is better to Check with basis team first.
