The unload and load utilities for the Adabas triggers and stored procedures facility are part of the online Trigger Maintenance facility and are run in a Natural environment:
| Utility | ... is used to |
|---|---|
| TRGUNLD | unload trigger definitions from the Adabas trigger file and related file-field table entries and write them to a work file. |
| TRGLOAD | load trigger definitions and related file-field tables from the TRGUNLD work file into the trigger file. |
The work file for TRGUNLD is a Natural work file (work file 1) that is defined either
in the batch job; or
to the Natural environment where the unload utility is running.
The TRGUNLD work file is used as input to the TRGLOAD utility.
A report is prepared at the end of the unload or load summarizing the triggers processed.
This document covers the following topics:
To invoke a utility:
Issue the name of the utility (TRGUNLD or TRGLOAD) as a command, optionally followed by a parameter list.
Parameters are used to limit the triggers to be processed.
Individual parameter values must be separated by the input delimiter (ID): the default is a comma ",". The input-mode parameter IM should be set to delimiter mode IM=D.
When executing a utility as a batch job, the batch job must log on to the SYSTRG library before executing the selected utility and its parameter list.
If the TRGULND utility is invoked from the command line in the online system without a parameter list, the following window is presented:

Enter values for the parameters as needed to limit the trigger definitions being unloaded. Any parameters left blank assume the default values.
If no parameters are specified for TRGUNLD, all triggers on the trigger file are unloaded and the related file-field table entries as well.

If no parameters are specified for TRGLOAD, all triggers and file-field table entries found on the TRGUNLD work file are loaded into the trigger file.
The following "wildcard" or special character notation can be used in values specified for FILE and FIELD parameters discussed in the following sections for each utility:
| Character | Example | Load triggers with file or field names... |
|---|---|---|
| * | PERS* | that start with "PERS" |
| > | PERS> | that have a value greater than "PERS" |
| < | PERS< | that have a value less than "PERS" |
The following parameters are available to limit the triggers unloaded from the trigger file into the work file during TRGUNLD processing (the default value for each parameter is "*" to include all possibilities):
| Parameter | Description | ||||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| FILE |
|

| PRE |
|

TRGUNLD FILE=EMPLOYEES
Specifying the FILE parameter limits the triggers unloaded to those defined for the specified file, in this case the EMPLOYEES file.
TRGUNLD FILE=VEHICLES,PRE=Y,ACT=A,TYPE=N
Combining parameters further limits the triggers unloaded. In this case, only active, non-participating pre-triggers defined for the VEHICLES file are unloaded. Note that the parameters must be separated by the input delimiter as specified in the ID parameter in the Natural environment.
The following parameters are available to limit the triggers loaded from the TRGUNLD work file to the trigger file during TRGLOAD processing:
| Parameter | Description | ||||||
|---|---|---|---|---|---|---|---|
| FILE |
|
||||||
| FIELD |
|
||||||
| FFT |
|
||||||
| REPLACE |
|
||||||
TRGLOAD FILE=EMP*
Load into the trigger file all file-field table entries and triggers found on the TRGUNLD input work file for files starting with "EMP".
TRGLOAD FFT=N,REPLACE=Y
Ignore any file-field table entries read from the work file. If any trigger definition read from the work file has the same specifications as an existing trigger definition, replace the existing definition with the definition from the work file.
A report is written out at the end of the unload process stating the number of trigger definitions and the number of file-field table entries unloaded.
The first page of the report indicates the source file and database for unloading the triggers and summarizes the selection criteria. Following this is a list of each record being unloaded into the work file:
18:12:00 ***** TRIGGERS UNLOAD UTILITY ***** YYYY-MM-DD DBAUSER Unloading from Trigger File 12 on Database 105 Rec File Details --- ----- ----------------------------------------------------------- Unloading Pre and Post Triggers for file(s) * and field name(s) * for all command types FFT 45 ZB-FIELD (ZB,2,A) FFT 45 ZF-FIELD (ZF,2,A) FFT 45 ZZ-FIELD (ZZ,4,P) TRG 45 CMD=R FLD=ZB PRTY=01 PGM=RBEGIMU PRE=S TYP=P PRM=C RB=U GRP 4 Group Record FFT 4 ADDRESS-LINE (AI,20,A) FFT 4 AREA-CODE (AN,6,A) FFT 4 BIRTH (AH,6,U) . . . |
The end of the report lists a summary count of records written to the work file. The physical work file written includes these records plus two additional records used for internal purposes.

The final page of the report summarizes the triggers unloaded by catagories. This report is useful for cross-checking with the TRGLOAD utility.
