|

|

<div><p>When you create a journal receiver with iSeries™ Navigator or the Create Journal
|
|||
|
|
Receiver (CRTJRNRCV) command, you specify a disk space threshold that indicates
|
|||
|
|
when you want the system to warn you or take action.</p>
|
|||
|
|
<p><img src="./delta.gif" alt="Start of change" />On the CHGJRN command, you can use the Journal Receiver Threshold
|
|||
|
|
(THRESHOLD) parameter to change the next receiver's threshold when specified
|
|||
|
|
in combination with JRNRCV(*GEN).<img src="./deltaend.gif" alt="End of change" /></p>
|
|||
|
|
<p>When the receiver reaches that threshold, the system takes the action specified
|
|||
|
|
in the manage receiver (MNGRCV) parameter for the journal. The default storage
|
|||
|
|
threshold is 1 500 000 KB.</p>
|
|||
|
|
<p>In specifying a storage threshold, you need to balance the amount of space
|
|||
|
|
that you have available with the additional system resources that are used
|
|||
|
|
to change journal receivers frequently.</p>
