<div><p>Journaling and commitment control are the preferred methods for
|
||
|
|
data and transaction recovery on the <span class="keyword">iSeries™</span> system.
|
||
|
|
You can use the COMMIT parameter to protect your file with journaling and
|
||
|
|
commitment control.</p>
|
||
|
|
<p>Database file journaling is started by running the Start Journal Physical
|
||
|
|
File (STRJRNPF) command for the file. Access path journaling is started by
|
||
|
|
running the Start Journal Access Path (STRJRNAP) command for the file or by
|
||
|
|
using System-Managed Access-Path Protection (SMAPP). You tell the system that
|
||
|
|
you want your files to run under commitment control through the Start Commitment
|
||
|
|
Control (STRCMTCTL) command and through high-level language specifications.
|
||
|
|
You can also specify the commitment control (COMMIT) parameter on the Open
|
||
|
|
Database File (OPNDBF) and Open Query File (OPNQRYF) commands. </p>
|
||
|
|
<p>If you are performing insert, update, or delete operations on a file that
|
||
|
|
is associated with a referential constraint and the delete rule, update rule,
|
||
|
|
or both are other than RESTRICT, you must use journaling. </p>
