Question:
When applying CA-DB2 maintenance to the CDBALOAD library, do the Xmanager, and IDB2's PC and DC started tasks need to be stopped?
Answer:
When applying maintenance to the CA DB2 Tools' executing libraries, you will need to stop the Xmanager, and IDB2's PC and DC started tasks.

Per maintenance Holddata:
*******************************************************************************************************
Please do not apply maintenance to the Xmanager runtime libraries with 
Xmanager active as it may result in a discrepancy between 
dynamically loaded components and statically loaded components. 
This may result in unpredictable behavior with CA-DB2 tools and/or may 
compromise the operating system/DB2 including possible failures.
