n is the full path to an existing directory. The default is <install-dir>\mgr\journal\.
CurrentDirectory is the name of a directory in which to store the journal files (the primary directory). When installed, the initial value of this field is “”. After InterSystems IRIS® data platform starts for the first time, the actual journal directory is filled in here, such as <install-dir>\mgr\journal.
Changing This Parameter
On the Journal Settings page of the Management Portal (System Administration > Configuration > System Configuration > Journal Settings), in the Primary journal directory row, select Browse. Select the name of an existing directory.
Instead of using the Management Portal, you can change CurrentDirectory in the Config.Journal class (as described in the class reference) 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).
