|
||
|
|
<div><div class="section"><p>Journal standby state is a separately purchased feature that prevents
|
||
|
|
most journal entries from being entered into the journal. Standby state is
|
||
|
|
option 42 of the i5/OS<sup>®</sup> operating system. You can start or stop journaling
|
||
|
|
while the journal is in standby. However, while a journal is in standby state,
|
||
|
|
you cannot use explicit commitment control. Also, databases files that have
|
||
|
|
referential integrity constraints or data links defined cannot be used when
|
||
|
|
a journal is in standby state. The operating system needs to use commitment
|
||
|
|
control for these functions. However, referential integrity constraints can
|
||
|
|
be used in standby state if RESTRICT is specified on the ON UPDATE or ON DELETE
|
||
|
|
attribute for the constraint.</p>
|
||
|
|
<p>An example of when you might want to put
|
||
|
|
a journal on standby state is if the journal is on a backup system. By having
|
||
|
|
the journal in standby state, a switchover to the target system can be accomplished
|
||
|
|
more quickly because all objects on the backup system can be journaled thus
|
||
|
|
allowing the switchover processing to skip the costly step of starting journaling
|
||
|
|
for all objects. At the same time though, the backup system is not incurring
|
||
|
|
the overhead of journaling because most journal entries are not deposited
|
||
|
|
when the journal is in standby state.</p>
|
||
|
|
<p>If there is an attempt to deposit
|
||
|
|
a journal entry when the journal is in standby state, no entry is deposited,
|
||
|
|
but no error messages are sent to the application. Journal codes 'J' and entry
|
||
|
|
types 'SI' and 'SX' are deposited when the local journal is put into and out
|
||
|
|
of standby. Furthermore, there are some journal entries that will be deposited
|
||
|
|
in a journal, even though the journal state is standby. Use the Journal entry
|
||
|
|
information finder to see if a journal entry is still deposited even though
|
||
|
|
the journal in standby state.</p>
