ARF allows automation of customized recovery procedures for production jobs. The recovery procedures for an ARF condition can include the following:
Note: For more information about ARF, see the Database Maintenance Guide.
In the definition of an ARF condition, you can code up to seven recovery action statements. When an ARF condition is detected, CA WA CA 7 Edition scans the ARF definition to determine the recovery actions to process.
Each recovery action statement (except AW statements) can cause the execution of one or more CA WA CA 7 Edition terminal commands. Although the format of the command must follow conventions used for batch terminal or SASSTRLR input, ARF responses use neither of these terminal types. Instead, ARF requires that one or more terminals be defined in the initialization file as DEVICE=TRXDV. These TRX terminals are similar to the trailer terminal (DEVICE=TRLDV), except they are dedicated for use by functions internal to CA WA CA 7 Edition such as ARF.
Because ARF recovery actions are processed as CA WA CA 7 Edition terminal commands, a valid logon is required for each ARF recovery transaction. The ID for this logon is supplied on the AR.3 panel in the RESPONSE-ID field. This ID requires the authority for all transactions that are executed in response to the ARF condition with which they are associated. If several TRX terminals are coded in the initialization file, the ID must be valid for ALL of these terminals because ARF transactions can be scheduled on any of these terminals.
If the RESPONSE-ID does not have the authority to execute the responses in its ARFSET, ARF recovery is not handled properly.
