<h1 class="topictitle1">Recommendations for trigger programs</h1>
|
||
|
|
<div><p>Here are the recommendations for a trigger program.</p>
|
||
|
|
<div class="section"><ul><li>Create the trigger program so that it runs under the user profile of the
|
||
|
|
user who created it. In this way, users who do not have the same level of
|
||
|
|
authority to the program will not encounter errors.</li>
|
||
|
|
<li>Create the program with USRPRF(*OWNER) and *EXCLUDE public authority,
|
||
|
|
and do not grant authorities to the trigger program to USER(*PUBLIC). Avoid
|
||
|
|
having the trigger program altered or replaced by other users. The database
|
||
|
|
calls the trigger program even if the user causing the trigger program to
|
||
|
|
run has authority to the trigger program.</li>
|
||
|
|
<li>Create the program as ACTGRP(*CALLER) if the program is running in an Integrated
|
||
|
|
Language Environment<sup>®</sup> (ILE). This allows the trigger program to run under
|
||
|
|
the same commitment definition as the application.</li>
|
||
|
|
<li>Open the file with a commit lock level the same as the application's commit
|
||
|
|
lock level. This allows the trigger program to run under the same commit lock
|
||
|
|
level as the application.</li>
|
||
|
|
<li>Create the program in the physical file's library.</li>
|
||
|
|
<li>Use commit or rollback in the trigger program if the trigger program runs
|
||
|
|
under a different activation group than the application.</li>
|
||
|
|
<li>Signal an exception if an error occurs or is detected in the trigger program.
|
||
|
|
If an error message is not signalled from the trigger program, the database
|
||
|
|
assumes that the trigger ran successfully. This might cause the user data
|
||
|
|
to end up in an inconsistent state.</li>
