Handling Data Set Contention

Hosted CA Health Checks may have data sets allocated to them. If other processes require exclusive control of those data sets, they will be in contention with the CAHCHECK address space. You do not need to shut down the CAHCHECK address space to resolve the contention. Use the DISPLAY ALLOC command to determine which check owner has the data set:

F CAHC,DISPLAY ALLOC

Displays all data sets allocated to all checks

F CAHC,D A,DSN=data.set.name

Displays a specific data set

F CAHC,D A DSN=generic.data.set* 

Displays all data sets matching partial name up to the asterisk

The check owner task name is displayed in the response to this command. You can then terminate the checks belonging to the check owner with the STOP command:

F CAHC,STOP ownertask

Stop the checks and cause deallocation of data sets
