Increase Java Heap Memory for TM1Web

TM1Web runs on a Java-based web server (Tomcat or WebSphere), and JVM memory allocation plays a crucial role.

 Optimize Session Management & Cache in TM1Web

• Reduce SessionTimeout in web.xml

• Default: 30 minutes → Set to 15-20 minutes to free up memory faster.

Tune TM1 Server (tm1s.cfg) Memory Settings

Optimize TM1 Server to reduce unnecessary memory consumption in TM1Web.

Recommended Configurations:

• Optimize Memory for Large Datasets:

MaximumMemoryThreshold=80

Optimize TM1Web Logging to Reduce Overhead

Excessive logging consumes memory. Reduce unnecessary logs:

Change DEBUG → WARN:

Increase Windows Virtual Memory

Scale TM1Web with Load Balancing (For High Users)

Deploy TM1Web on multiple Tomcat instances behind a load balancer

Thank you Ahmed,

I will try this settings and see if it fits to our environment.

Thanks.
