How to Define Transaction Recovery

Customization of transaction recovery consists of:
  • Determining which application program (TP) transactions will have recovery automation
  • Identifying the batch message region (BMP) transactions that will have recovery automation
  • Specifying the error threshold level that a recovery should stop at
  • Identifying specific abend codes that you want recovery procedures to occur for
  • Specifying the recovery procedure, which usually consists of invoking a command, a routine, and/or sending notifications to an operator

The recovery itself is typically triggered from the NetView automation table by calling the EVIECT0X routine when certain messages arrive at NetView. EVIECT0X then consults the automation policy to find out whether recovery is to be attempted and to determine what has to be done.

The following sections illustrate the configuration process.
