<h1 class="topictitle1">Where the replication of journal entries start</h1>
<div><p>When you specify a journal receiver for remote journaling, you
are specifying where the replication of journal entries will start.</p>
<p>You can choose from the following options:</p>
<div class="section"><h4 class="sectiontitle">Attached receiver on target system</h4><p>The replication
of journal entries starts with the journal receiver that is currently attached
to the remote journal on the target system. The journal entries are replicated
from the corresponding journal receiver that is associated with the journal
on the source system. The replication starts with the journal entries that
follow the last journal entry that currently exists in the attached journal
receiver on the target system.</p>
<p>The remote journal on the target system
might not have an attached journal receiver. If this occurs, the journal receiver
that is currently attached to the journal on the source system is created
on the target system. That journal receiver is then attached to the remote
journal on the target system. Then journal entries are replicated starting
with the first journal entry in the journal receiver that is currently attached
to the journal on the source system.</p>
<p>If the journal on the source system
does not have an attached journal receiver, no journal entries can be replicated,
and an error is returned. This is only possible in the case of a remote journal
that is associated with another remote journal.</p>
<p>To use this option specify
one of the following:</p>
<ul><li><img src="./delta.gif" alt="Start of change" />Use the *ATTACHED special value for the Starting
journal receiver (STRJRNRCV) parameter on the Change Remote Journal (CHGRMTJRN)
command.<img src="./deltaend.gif" alt="End of change" /></li>
<li>Use the <span class="uicontrol">*ATTACHED</span> special value for the Starting
journal receiver <span class="uicontrol">(STRJRNRCV)</span>parameter on the <span class="uicontrol">Change
Remote Journal (CHGRMTJRN)</span> command. </li>
</ul>
</div>
<div class="section"><h4 class="sectiontitle">Attached receiver on source system only</h4><p>The replication
of journal entries starts with the journal receiver that is currently attached
to the journal on the source system.</p>
<p>If the corresponding journal receiver
exists and is attached to the remote journal on the target system, journal
entries are replicated. Replication starts with the journal entries that follow
the last journal entry that currently exists in the attached journal receiver
on the target system. Otherwise, if the corresponding journal receiver exists
but is not attached to the remote journal on the target system, no journal
entries can be replicated. The system returns an error.</p>
<p>If the corresponding
journal receiver does not exist on the target system, the journal receiver
is created and attached to the remote journal on the target system. Journal
entries then are replicated starting with the first journal entry in the journal
receiver that is currently attached to the journal on the source system.</p>
<p>If
the journal on the source system does not have an attached journal receiver,
journal entries cannot be replicated, and the system returns an error. This
is only possible in the case of a remote journal that is associated with another
remote journal.</p>
<p>To use this option specify one of the following:</p>
<ul><li><img src="./delta.gif" alt="Start of change" />Use the *SRCSYS special value for the Starting journal receiver
(STRJRNRCV) parameter on the Change Remote Journal (CHGRMTJRN) command.<img src="./deltaend.gif" alt="End of change" /></li>
<li><span class="uicontrol">Use attached receiver on source system only</span> in
the <span class="uicontrol">Activate</span> dialog in iSeries™ Navigator.</li>
</ul>
</div>
<div class="section"><h4 class="sectiontitle">Qualified journal receiver name</h4><p>The replication
of journal entries starts with the specified journal receiver name for the
journal on the source system.</p>
<p>If the corresponding journal receiver
exists and is attached to the remote journal on the target system, journal
entries are replicated. Replication starts with the journal entries that follow
the last journal entry that currently exists in the attached journal receiver
on the target system. Otherwise, if the corresponding journal receiver exists
but is not attached to the remote journal on the target system, no journal
entries can be replicated. The system returns an error.</p>
<p>If the corresponding
journal receiver does not exist on the target system, the journal receiver
is created and attached to the remote journal on the target system. Journal
entries then are replicated starting with the first journal entry in the specified
journal receiver.</p>
<p>If the journal on the source system is not associated
with the specified journal receiver, no journal entries can be replicated,
and an error is returned.</p>
<p>The creation of any receiver on the target
system by the change journal state processing is performed as though the receiver
was being saved and restored to the target system. Therefore, the ownership
of the receiver on a target system will follow the same rules as with the
existing save and restore functions. If the user profile which owns the receiver
on the source system is on the target system, then that profile will own the
created receiver on the target system. If the user profile does not exist
on the target system, then the profile QDFTOWN will own the receiver on the
target system.</p>
<p><img src="./delta.gif" alt="Start of change" />Additionally, information such as the audit
attributes, public authority, and primary group of the source journal receiver
at the time it was attached to the source journal will be incorporated into
the created journal receiver on the target system. If the owner, owner's authority,
public authority, primary group, or audit attributes of the source system's
receiver are changed, those changes will be propagated to the target system
when the next receiver is attached to the target journal. Changes made to
other private authorities of the source system's receiver must be maintained
separately on the target system.<img src="./deltaend.gif" alt="End of change" /></p>
<p>If the library for the journal receiver
resides in an ASP, the journal receiver will be created in that ASP. The remote
journal function does not support nonlibrary ASPs for the ASP of the remote
journal receiver. See Journal receiver disk pool considerations for more information.</p>
