When we need to perform some maintenance in an application Server, we are stop this APL. During these steps, no problem in the XI System.
We have the same procedure to startup and we only put APL again, the central instance is not affect and all XI components will be running well, but during the APL startup, in the SMGW transaction we can see the ID AI_RUNTIME_XP0 for this APL, before all XI components will be available.
This situation is causing a lot of problems in the interfaces. During
this startup period, we can see this error messages
Received XI System Error in Integration Engine. ErrorCode:
JCO_SYSTEM_FAILURE ErrorText:
ErrorStack: "SYSTEM FAILURE" during JCo call. Bean
SMPP_CALL_JAVA_RUNTIME3not found on host apl54, ProgId
=AI_RUNTIME_XP0: P
(In this example, the APL was apl54).
Is there a special procedure to boot the APL ?
