CHKP DSN mismatch with sysplex MEMBER=member_name; DSN=file_name
Application Performance Analyzer has detected that another Application Performance Analyzer member of the same sysplex group, is using a different checkpoint file name. All members of the same group must use the same checkpoint file name.
Application Performance Analyzer terminates.
Change the checkpoint file names in the configuration of sysplex members member_name, file_name, or both so that they match, and then stop and restart these tasks.
