The IBM Health Checker for z/OS is used to identify potential problems before they impact availability or cause outages. The Health Checker outputs messages to notify the user of the problems and suggests actions to be taken. The messages can be merely informational, or they can indicate a risk to the operation of the product.

ICSF provides a set of health checks to inform the user of potential ICSF problems. The checks include both migration checks and status checks. A migration check is designed to warn of changes in a current or pending ICSF release that could negatively impact usage. A status check provides information on the state of ICSF.

The ICSF Health Checks are:

• ICSFMIG7731_ICSF_RETAINED_RSAKEY
• ICSFMIG_DEPRECATED_SERV_WARNINGS
• ICSF_COPROCESSOR_STATE_NEGCHANGE
