When applying CA-DB2 maintenance to the CDBALOAD library, do the Xmanager, and IDB2's PC and DC started tasks need to be stopped?
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.
