Environment

Novell Access Manager 3.1 Administration Console (Windows and Linux based)
Novell Access Manager 3.1 Support Pack 4 applied

Situation

Access Manager setup and working fine. Due to internal needs and the number of users accessing the protected resources, the number of Linux Access Gateway (LAG) clusters defined in the Admin Console as well as the number of nodes in each cluster has increased (currently have 20 LAG nodes across 2 seperate LAG clusters). As more devices were added to the setup, logging into and browsing the Admin Console became noticeably slower.

Resolution

Modify the following files on the Admin Console before restarting the host:

- /opt/novell/devman/share/conf/platform.conf
<stringParam name="PRIORITYEXECUTOR_MAX_THREADS"  value="20"/>

This parameter increases the concurrent thread capacity.


- /opt/novell/devman/share/conf/sc.conf
<stringParam name="HealthFrequencyInSeconds" value="1200"/>
<stringParam name="MonitoringFrequencyInSeconds" value="1200"/>

This parameter increases the delay in fetching health status, this is for background process.

- /opt/novell/devman/share/conf/vcdn.conf
 <romaCommunication ldapAccessToDatastore="true" />

Makes use LDAP rather than LDAPS to communicate with edir to make the various operation faster. This is used when the Admin Console Application communicates with the local eDir present on the host.
