n is the full path to a valid directory. The maximum length is 226 characters. By default, no directory is listed.
wijdir is the name of the directory where the write image journal file is stored. InterSystems recommends that the journal directory be located in a different partition from your databases.
If no value is specified, InterSystems IRIS® data platform uses the install-dir/mgr directory.
Changing This Parameter
On the Journal Settings page of the Management Portal (System Administration > Configuration > System Configuration > Journal Settings), in the Write image journal directory row, select Browse. Select a directory name.
Instead of using the Management Portal, you can change wijdir in the Config.configOpens in a new tab 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).
