Have you tested the rfc?

[Former Member]

yes..the TCP/IP connection AI_RUNTIME_JCOSERVER has errors.

Do we need to restart the XI instance?

Hi,

can you check whether your SAP Java stack is available ?

if so, check whether if you AI_JCO_RUNTIME config properly, e.g., program id correct, Gateway correct, same program id on java side ?

Cheers,

Aaron
