8.5 Using EXIT_PARAMS

Use EXIT_PARAMS to supply information to the user exit routine, such as the program name and user-defined parameters. You can process a single data record multiple times.

Table 8-3 User Exit Input

Exit parameter	Description
`PROGRAM_NAME`	Specifies the full path and name of the calling process, for example `\ggs\extract` or `\ggs\replicat`. Use this parameter when loading an Oracle GoldenGate callback routine using the Windows API or to identify the calling program when user exits are used with both Extract and Replicat processing.
`FUNCTION_PARAM`	Allows you to pass a parameter that is a literal string to the user exit. Specify the parameter with the `EXITPARAM` option of the `TABLE` or `MAP` statement from which the parameter will be passed. See "EXITPARAM 'parameter'". This is only valid during the exit call to process a specific record. `FUNCTION_PARAM` can also be used at the exit call startup event to pass the parameters that are specified in the `PARAMS` option of the `CUSEREXIT` parameter. (See "CUSEREXIT".) This is only valid to supply a global parameter at exit startup.
`MORE_RECS_IND`	Set on return from an exit. For database records, determines whether Extract or Replicat processes the record again. This allows the user exit to output many records per record processed by Extract. To request the same record again, set `MORE_RECS_IND` to `CHAR_NO_VAL` or `CHAR_YES_VAL`.
