The CA-DB2 Tools health check routines are registered to IBM Health Checker for z/OS during CA Execution Manager for DB2 for z/OS (PXM) startup. The intended implementation of IBM Health Checker for z/OS is that by default, health check routines should execute as part of the product "out of the Box" installation. CA-DB2 Health Checks conform to this standard. CA-DB2 Tools health check routines, depending on execution interval time, may run once or periodically for the duration of the Xmanager started task.
