GDG Support
The Automation Engine also supports Generation Data Groups (GDG). This type of file management can be used in FILE event objects and the script element GET_EVENT_INFO.
FILE Event
A standard function of this object type is to check file system values. Additionally, you can trigger an event if a GDG generation is closed. In the File Event page, File Event section, enter a z/OS host, and in the Timer Parameters section select the option Automatically to use this function.
Note: The closing of a new generation is waited for if GDG(+1) has been specified, which is normally the case. If you specify GDG with +/-0 (+0, +00, +000, -0, -00, -000), the closing of the current generation is waited for.
Example:
PAYROLL Name of the GDG
DSNAME=PAYROLL(0) This week's generation data set
DSNAME=PAYROLL(-1) Last week's generation data set
DSNAME=PAYROLL(-2) Generation data set of two weeks ago
Script Element GET_EVENT_INFO
This script function retrieves the name of a generation which can then be processed.
Example
:SET &FILENAME# = GET_EVENT_INFO (FILENAME)
:SET &HND# = PREP_PROCESS_FILE ("MVSHOST", &FILENAME#)
Configuration
Some specifications are required in order to use GDG in your AE system:
- Activate the parameter smfwrite= in the INI file of the z/OS agent. For more information, see Agent z/OS.
- Activate the exit modules IEFU83 and IEFU84.
- The entries 14, 15, 30 and 64 must be logged.
