Enable the MUF

CA Datacom/AD includes built-in support for Automatic Restart Management (ARM). You must enable this support for High Availability.

Note: If ARM is not enabled, you can rerun Automatic Configuration or can edit the jobs manually, as noted in this procedure. For Automatic Configuration details, see the Installation Guide.

Follow these steps:

Confirm that the CPYAXDAT job was run from chorus_runtime_hlq.CETJJCL to copy the sample AXDATIN1 and AXDATIN2 members from chorus_runtime_hlq.CETJOPTN to datacomad_adchlq.CUSMAC.
Edit the Multi-User Facility (MUF) control options file in AXDATIN1, which resides in datacomad_adchlq.CUSMAC:
1. Uncomment the ARM option, which is the first line in OPTIONAL START-UP PARMS FOR AXDATIN1.
2. Ensure that the element name corresponds to an element name that is defined in the ARM policy. The default is CHORMUF.
Restart the CA Datacom/AD database MUF:
```
S your_muf_name
```
The following messages appear:
- Message DB00212I appears on the z/OS console to identify the release of CA Datacom/AD that you have installed.
- Message DB00201I appears on the z/OS console to indicate that the MUF is up.
Important! Confirm that the MUF started before you continue.
