Hi Peter, If the hold data says you need an IPL, you need an IPL. Modules in SYS.NUCLEUS are loaded into memory very early in the IPL process, and cannot usually be replaced without an IPL.

Applying UJ08463 updates SYS1.NUCLEUS(IECDDDSR), Hold data says that an IPL with CLPA is needed. Instead of an IPL, can I just copy only this module to production SYS1.NUCLEUS and give an LLA refresh? Just trying to see if an IPL can be avoided. Or an IPL is what needs to be done ? Any suggestions based on your experience will help me.
