The default Java heap size may be insufficient for the UMS Console. This usually happens if you have

• a large number of devices registered (>10.000)

• a lot of devices in one folder (a flat directory structure under Devices in the UMS Console; >1.000 per folder)

Solution: Change Java Heap Size for the UMS Console

For the UMS Console, you can modify the Java heap size during the UMS update/installation. For details, see IGEL UMS Installation under Windows. You can also modify the heap size as follows:

1. Close the UMS Console.
   

2. Open the following file:
   Default path on Windows:  C:\Program Files\IGEL\RemoteManager\rmclient\RMClient.config
   Default path on Linux: /opt/IGEL/RemoteManager/rmclient/RemoteManager.config
   

3. Find the line vmparam -Xmx3072m and change the -Xmx value according to your needs. (Default: 3072 MB)

   Note

   The Java heap size is defined INDIVIDUALLY depending on the configuration of the server and your UMS environment, but must be less than the amount of available physical RAM. General recommendations can be found in the Oracle article Tuning Java Virtual Machines (JVMs); see also the -Xmx option there. Note also the following: All heap size changes are at your own risk! Change the heap size only if you know exactly what you are doing. In the case of improper configuration, the UMS Console will be unable to run. Reducing the memory may affect the function of the UMS and is NOT recommended.

   
   

2. Save the changes.
   

3. Restart the UMS Console.
