The default session timeout of 45 minutes is some of my clients too short or contradicts the company’s internal security policy.
To check which session timeout is currently active, you can deduct the following command.
[oracle@ccserver ~]$ emctl get property -sysman_pwd <SYSMAN_PWD> -name oracle.sysman.eml.maxInactiveTime Oracle Enterprise Manager Cloud Control 12c Release 188.8.131.52.0 Copyright (c) 1996, 2012 Oracle Corporation. All rights reserved. Value for property oracle.sysman.eml.maxInactiveTime for oms ccserver.example.com:4890_Management_Service is null
If you wanted to set the timeout higher or e.g. to unlimited, you can use the following command.
oracle@ccserver bin]$emctl set property -sysman_pwd <SYSMAN_PWD> -name oracle.sysman.eml.maxInactiveTime -value -1 Oracle Enterprise Manager Cloud Control 12c Release 2 Copyright (c) 1996, 2012 Oracle Corporation. All rights reserved. Property oracle.sysman.eml.maxInactiveTime has been set to value -1 for all Management Servers OMS restart is required to reflect the new property value
A value of -1 means in this case a unlimited timeout, otherwise, you pass (in minutes) an input you want to adjust. Dont forget that the change of the value a restart of all management server is required.
As always, I Happy about comments
