<div><p>Using a data area named QDFTJRN, you can automatically start journaling
|
||
|
|
when a non-integrated file system object (data area, data queue, or file)
|
||
|
|
is created, moved, or restored into the library, thus, ensuring the very first
|
||
|
|
change to the object will be recorded in the journal and that no lock on the
|
||
|
|
user's part prevents journaling from starting in the library. The QDFTJRN
|
||
|
|
data area must exist in the library where the object is being added. </p>
|
||
|
|
<div class="note"><span class="notetitle">Note:</span> <ul><li>The QDFTJRN data area must be created by the user.</li>
|
||
|
|
<li>To automatically start journaling for integrated file system objects,
|
||
|
|
see the discussion of journal inheritance in <a href="rzakistrjrn.htm">Journal
|
||
|
|
integrated file system objects</a>. </li>
|
||
|
|
</ul>
|
||
|
|
</div>
|

|
|
<p><img src="./delta.gif" alt="Start of change" />If a data area called QDFTJRN exists 1) in the same library
|
||
|
|
into which the data area, data queue, or physical file is created, or 2) in
|
||
|
|
the same schema that the SQL table is created into, and 3) the user (in either
|
||
|
|
instance) is authorized to the data area, journaling will be started to the
|
||
|
|
journal named in the data area if all the following are true: <img src="./deltaend.gif" alt="End of change" /></p>
|
||
|
|
<ul><li><img src="./delta.gif" alt="Start of change" />The identified library for the data area, data
|
||
|
|
queue, or physical file or identified schema for the SQL table must not be
|
||
|
|
QSYS, QSYS2, QRECOVERY, QSPL, QRCL, QRPLOBJ, QGPL, QTEMP, or any of the independent
|
||
|
|
auxiliary storage pool (IASP) equivalents to these libraries. (An iASP equivalent
|
||
|
|
of QRPLOBJ, for example, is QRPLxxxxx where 'xxxxx' is the number of a primary
|
||
|
|
auxiliary storage pool (ASP).) <img src="./deltaend.gif" alt="End of change" /></li>
|
||
|
|
<li>The journal specified in the data area must exist and the user must be
|
||
|
|
authorized to start journaling to the journal. </li>

|
|
</ul>
|
||
|
|
<p><img src="./delta.gif" alt="Start of change" />See the table below for a detailed description of the values
|
||
|
|
within the data area.<img src="./deltaend.gif" alt="End of change" /></p>
|
||
|
|
<p><img src="./delta.gif" alt="Start of change" />When creating SQL tables within a schema, the QSQJRN journal
|
||
|
|
within the schema is used to start journaling the tables. To start journaling
|
||
|
|
the tables to a different journal than QSQJRN within the schema, create the
|
||
|
|
QDFTJRN data area in the schema and specify a different journal name inside
|
||
|
|
the QDFTJRN data area.<img src="./deltaend.gif" alt="End of change" /></p>
|
||
|

<p>This table shows formats of the QDFTJRN data area.</p>
