<h1 class="topictitle1">Swap journal receiver operations with remote journals</h1>
|
||
|
|
<div><p>To swap journal receivers on a remote journal, perform a swap journal
|
||
|
|
receiver operation on the source system to attach a new receiver to a local
|
||
|
|
journal. When this happens, the remote journal function automatically attaches
|
||
|
|
a new receiver to the remote journals that are currently being
|
||
|
|
maintained synchronously or asynchronously.</p>
|
||
|
|
<p>If the journal sequence numbers were reset as part of the swap journal
|
||
|
|
receiver operation performed for the local journal, the remote journal function
|
||
|
|
will also reset the journal sequence number for each remote journal. This
|
||
|
|
keeps the journal sequence numbers synchronized between the local journal
|
||
|
|
and the remote journal. For remote journals that are being synchronously maintained,
|
||
|
|
a coordinated swap journal receiver operation is performed for the local journal
|
||
|
|
on the source system and the remote journals on the target systems. For asynchronously
|
||
|
|
maintained remote journals, the new receiver is attached when the target system
|
||
|
|
receives the journal entry with journal code 'J' and entry type 'PR' (previous
|
||
|
|
receiver).</p>
|
||
|
|
<p>If the swap journal receiver operation fails on the target system, the
|
||
|
|
remote journal function ends for that remote journal, and processing continues
|
||
|
|
on the source system. The system sends a message to the journal message queue
|
||
|
|
that indicates that the remote journal function failed. When applicable, the
|
||
|
|
system sends remote journal failure type messages to the related journal message
|
||
|
|
queues on both the affected source and target systems. See Work with remote
|
||
|
|
journal error messages for more information.</p>
|
||
|
|
<p>You cannot initiate a swap journal receiver operation to attach a new receiver
|
||
|
|
directly for a remote journal. New journal receivers are always attached to
|
||
|
|
the remote journal by the remote journal function as new receivers are attached
|
||
|
|
to the local journal. However, you can perform a change journal operation
|
||
|
|
on a remote journal to change several other attributes for the remote journal
|
||
|
|
such as the journal message queue or delete receivers value.</p>
|
||
|
|
<p>A swap journal receiver operation to attach a new receiver to a local journal
|
||
|
|
that has an associated remote journal in the catch-up phase can be performed.
|
||
|
|
This is regardless of whether the remote journal is currently being caught-up
|
||
|
|
from a detached or the currently attached receiver on the local system. The
|
||
|
|
catch-up phase of processing will not transition into synchronous or asynchronous
|
||
|
|
delivery mode until the end of the currently attached receiver for the local
|
||
|
|
journal is reached.</p>
