The CA Health Checker infrastructure modules are loaded into LPA during the initialization. The addresses of the various service routines are anchored into a control structure that does not move once it has been created. If you apply maintenance to any of the LPA resident modules, issue the following MVS console command after LLA has been refreshed:
SETPROG LPA,ADD,MODNAME=CASHCLPA,DSNAME=LNKLST,FIXED,PAGEPROTALL
The CA health Checker infrastructure automatically detects the new copy and updates the addresses that are anchored in the control structure. Then, it initiates an automatic refresh of all hosted health checks in the CAHCHECK address space. This action ensures that only the freshest copy of the infrastructure is being used.
Normally, if any maintenance requires this action, the instructions accompanying the PTF advise you.
