Class Reference   

Alternate location of the journal file.
[Journal]    AlternateDirectory=n
The value n 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 Caché starts for the first time, the actual journal directory is filled in here, such as c:\intersystems\cache\mgr\journal.
