Rules Facility Guide › VMXRPI Configuration File Reference › AVAILCHK Record › Description

Description

The AVAILCHK facility allows the CP component to determine that the service virtual machine is active and available to process requests.

When the Rules Facility is not initialized, the AVAILCHK facility generates message VMXRPW950 at count2 intervals.

When CA VM:Secure is initialized, the AVAILCHK facility checks the service virtual machine every 30 seconds to ensure that it is still active. If the service virtual machine is not responding, the AVAILCHK facility will first log on and then disable logon rules processing for the virtual machine, allowing you to log on to the virtual machine to act.

After each time period that the service virtual machine cannot process a request, it sends the operator the following warning messages:

After the operator logs on and restarts CA VM:Secure, it sends the following message that the service virtual machine is responding and can process requests:

VMXRPW959I VM:SECURE NOW RESPONDING TO AVAILABILITY CHECK.

Note: If you log on to CA VM:Secure with a full–screen terminal and leave the terminal in CP READ, HOLDING, or MORE... status, CA VM:Secure cannot process requests, and the AVAILCHK facility is invoked. This may cause the program to be non‑responsive.

Example

To specify that the operator gets a message every two minutes when the Rules Facility is not active, add the following record to the VMXRPI CONFIG file:

AVAILCHK 6 4

In the above example, 6 specifies that three minutes (six 30–second increments) are to elapse before logon rules are disabled for the service virtual machine when it is unable to process requests. The number 4 specifies that two minutes (four 30–second increments) are to elapse before the operator is notified that the Rules Facility is not active, CA VM:Secure is not logged on or is not running the system disconnected.
