Switch Journal Files
The system automatically switches the journal file in the following situations:
-
After a successful backup of an InterSystems IRIS database
-
When the current journal file grows to the maximum file size allowed (configurable on the Journal Settings page)
-
When the journal directory becomes unavailable and you specified an alternate directory
-
After updating settings in the Journal Settings page of the Management Portal (System Administration > Configuration > System Configuration > Journal Settings).
Switching the journal file is preferable to stopping and starting journaling because during the latter process, any global operations that occur after stopping but before restarting are not journaled.
To manually switch journal files:
-
Navigate to the Journals page of the Management Portal (System Operation > Journals).
-
Click Switch Journal above the list of database journal files.
-
Confirm the journal switch by clicking OK.
You can also switch journal files using the ^JRNSWTCH routine or by selecting option 3, Switch Journal File from the ^JOURNAL routine menu. See Switch Journal Files Using ^JRNSWTCH for details.
