Issue/Introduction:

Error Message :
U3000008 CP identifies itself as system '', CallAPI expects 'UC4 '
U3000002 Program 'UC4 Call Interface' version '9.00Axxx-xxx' ended abnormally.

A z/OS agent is upgraded from 9.00Axxx-xxx to 10.0.8+build.xxx.  However, the z/OS CallAPI is still referencing the old version 9.

Investigation:

1. Upgrade a v9 z/OS agent to v10 z/OS agent
2. Verify the UCXBM25C.INI file contains the correct information pointing to the Automation Engine v10 system
3. Run the CallAPI job 

Results
Actual:  

U3000000 Program 'UC4 Call Interface' version '9.00Axxx-xxx' Changelist '' started. 
U3000008 CP identifies itself as system '', CallAPI expects 'UC4 ' 
U3000002 Program 'UC4 Call Interface' version '9.00Axxx-xxx' ended abnormally.

Expected:
The CallAPI job ends successfully.


 

Cause:

Cause type:
Configuration
Root Cause: The v10 z/OS agent is referencing the v9 z/OS agent's loadlib, which is the default in the mainframe linklist.

Environment:

OS Version: N/A

Resolution:

Do a steplib in the CallAPI job to use the v10 loadlib. That way, the v10 z/OS agent uses the v10 loadlib that comes with the agent installation.
