### Grant Update Access to APPLDEV Group (RACF Command)

Source: https://www.ibm.com/docs/en/cics-bac/1.1.1/index_topic=profiles-examples-facility-class-definitions

This RACF command grants the APPLDEV group UPDATE access to all resources defined under the $CBK.CICSPROD.ADMIN.** profile. This allows the development group to create, view, and modify these specific resources.

```shell
PERMIT $CBK.CICSPROD.ADMIN.** CLASS(FACILITY) ID(APPLDEV) UACC(UPDATE)
```

### Deny All Access to CICSPROD Resources (RACF Command)

Source: https://www.ibm.com/docs/en/cics-bac/1.1.1/index_topic=profiles-examples-facility-class-definitions

This RACF command sets a default policy to deny all access to any resource within the CICSPROD application ID. It's the initial step before granting specific permissions.

```shell
RDEFINE FACILITY $CBK.CICSPROD.** UACC(NONE)
```

--------------------------------

### Define Specific Admin Object Profile (RACF Command)

Source: https://www.ibm.com/docs/en/cics-bac/1.1.1/index_topic=profiles-examples-facility-class-definitions

This RACF command defines a specific profile for the ADMIN object type within CICSPROD. This profile takes precedence over the general CICSPROD profile, allowing for more granular control.

```shell
RDEFINE FACILITY $CBK.CICSPROD.ADMIN.** UACC(NONE)
