Monitor the health checks generated for CA 1.
Business Value:
Health Checks alert you of conditions that could prevent CA 1 from running properly if left uncorrected, and they guide you in addressing the problem. These health checks provide best practices for running CA 1.
More Considerations:
The following health checks are provided for CA 1:
Monitors space in the CA 1 Audit file to help ensure that sufficient space is available to log all tape activity.
Monitors space in the CA 1 Audit file that is triggered after no steps were taken to address the problem that the low threshold check identified.
Monitors the availability of free DSNBs as a percentage of the total number of DSNBs defined in the TMC. This first, low threshold check provides an early notification that DSNBs are being used up.
Alerts users that they can be running short on free (unused) DSNB records in the TMC. This check is the secondary medium threshold check.
Inspects the first n number of DSNBs in the free DSNB chain to help ensure that none of them are found to be in use.
Helps ensure that the CA 1 TMC and Audit data sets are placed on different volumes.
Inspects the free (unused) DSNB chain for any active (used) DSNBs; however this check scans the entire free chain. This check is similar to the CA1_FREE_DSNB_QUICK_SCAN check.
Identifies possible problems that are associated with dynamic label change processing based on the CA 1 System Option DCHG.
Identifies possible problems that are associated with changing a label type based on the CA 1 System Option LCHG.
Identifies possible problems that are associated with changing the dynamic tape recording technique based on the CA 1 System Option TCHG.
Alerts users of situations where the mixing expiration date is being done so that it can be followed up and corrected.
Warns users that basic security setup has not been performed to protect the assets on tape. This exposure is associated with the setting of the CA 1 System Option FUNC. This feature controls the security checking to be done in the real-time nonresident (foreign) and label processing areas.
Raises an exception when it finds that security has not been set up for the CA 1 ISPF panels.
Verifies that access to the TMC is protected by the setting of CA 1 System Options YSVC and BATCH and rules in the external security system.
Warn users that basic security setup has not been performed to protect against unauthorized access to tapes. This exposure is associated with defining resource class CA@APE. If the external security is set to IBM RACF but the CA@APE resource class is not defined, tape jobs begin to fail.
Warn users that basic security setup has not been performed to control access to tapes and commands. This exposure is associated with defining the resource class CA@MD. If the external security is set to IBM RACF but the CA@MD resource class is not defined, users are not able to issue commands in the CA 1 ISPF panels.
