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.
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).
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.
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.
