n is either 1 or 0. The default value is 0.
When JournalcspSession is enabled (n = 1), InterSystems IRIS® data platform journals the %cspSession global. Enable this setting if you want the web session global to be replicated onto another machine for failover or if you want a web session to survive an InterSystems IRIS restart. Otherwise, the %cspSession global is mapped to IRISTEMP and not journaled. InterSystems IRIS kills the %cspSession global on system restart or upgrade to a new InterSystems IRIS software version, so that any record of ongoing web sessions is removed.
Changing This Parameter
On the Journal Settings page of the Management Portal (System Administration > Configuration > System Configuration > Journal Settings), select Journal Web session to enable this setting.
Instead of using the Management Portal, you can change JournalcspSession in the Config.JournalOpens in a new window 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).
