AlternateDirectory

Set the alternate location of the journal file.

Synopsis

[Journal]    AlternateDirectory=n

n is the full path to an existing directory. By default, no directory is listed.

Description

AlternateDirectory is the name of an alternate (secondary) directory in which to store journal files.

This alternate directory is used if the primary journal directory specified by CurrentDirectory is unavailable; for example, if the disk partition for the primary journal directory is full, offline, or has some other problem. For these reasons, InterSystems recommends that the alternate journal directory be located on a different disk than the current journal 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 Secondary journal directory row, select Browse. Select the name of an existing directory.

Instead of using the Management Portal, you can change AlternateDirectory 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).
