Set a journal file name prefix.
n is an alphanumeric string. The maximum length is 64 characters. The default is an empty string.
JournalFilePrefix is a string added to the start of the journal file name. For example, if JournalFilePrefix is set to Oct, the resulting journal file would look like Oct20191001.001.
Changing This Parameter
On the Journal Settings page of the Management Portal (System Administration > Configuration > System Configuration > Journal Settings), at the Journal file prefix row, enter a prefix.
Instead of using the Management Portal, you can change JournalFilePrefix in the Config.JournalOpens in a new tab class (as described in the class reference), from the ^JOURNAL Utility (as described in Update Journal Settings Using ^JRNOPTS), or by editing the CPF in a text editor (as described in the Editing the Active CPF section of the “Introduction to the Configuration Parameter File” chapter in this book).
