Java and abap stack connection

[Former Member]

Hello,

how to check connection b/w Java and ABAP stack.

I am getting below error :

SAP:Code area="MAPPING">JCO_SYSTEM_FAILURE</SAP:Code>

<SAP:P1>connection to partner 'localhost:0' broken / CPIC-CALL: 'ThSAPCMRCV' : cmRc=20 t</SAP:P1>

We did some upgrades of kernel and jvm and started getting this error.

Please suggest

Hello,

thanks but what does recreating AI_RUNTIME_JCOSERVER means? and how does it help?

Thats the TCP/IP (I beleive) type of RFC connection between the Java engine and the ABAP engine. If that connection is not working, the engines can not communicate with each other.

Hi,

In the SM59 TCP/IP connections you can find this "AI_RUNTIME_JCOSERVER".

When you were configuring some problem may come, so when you delete and reconfig/rebuild then that may be resolved.
