I am using DMC version 3.1.8.0.
After logging into DMC, 
I automatically get logged out after a few minutes. 
It seems to be due to session timeout...
What is the way to increase the DMC session timeout?
In DMC 2.1.x version, there is a page in the document called 'Managing session time out', 
but I can't find it in DMC 3.1.x version.
Thank you.

Hi JH, 

on page 37 in the document, which @Cintia Ogura mentions in this post: https://community.ibm.com/community/user/datamanagement/discussion/dmc-users-guide-v3110 Additional Security Parameters are described. In DMC 3.1.10 there is a setting for this timeout.
See also https://www.ibm.com/docs/en/db2-data-mgr-console/3.1.x?topic=securing-customize-security-parameters to find thefile
dswebserver_override.properties.

Cheers

Oh, I didn't even know there was a DMC user guide...
I've been monitoring with DMC, but I kept getting logged out, which was inconvenient,
but now it's resolved.
I opened a case and requested the DMC guide as well.
Thank you.
