The MID Server starts with a default JVM memory allocation, but you can modify this
setting in the configuration file.

## Warum und wann dieser Vorgang ausgeführt wird

In the base ServiceNow system, the MID Server JVM memory is set to 1024 MB, which is configured in the \\agent\\conf\\wrapper-override.conf file in the MID Server installation directory. This setting might not be appropriate for the way your organization uses the MID Server. If you want the MID Server to work harder, allocate more resources to it. If the MID Server is located in a small branch office and runs in an environment where memory allocation is shared between a print server, mail server, or web proxy server, the allocation might have to be reduced.  
Hinweis:  
For a complete list of minimum MID Server requirements, see [MID Server system requirements](https://servicenow-prod.fluidtopics.net/cz~U8SBK9UwjNYMyKIBxOA "Use these minimum system requirements to allocate resources for computers hosting MID Servers.").

## Prozedur

1. Open the \\ServiceNow\\\<MID Server name\>\\agent\\conf\\wrapper-override.conf file in a text editor.  
   For more information about this file, see [Installing Multiple MID
   Servers on a Single System](https://servicenow-prod.fluidtopics.net/Db6PQgljVCvKe3xyUBFoYw#t_InstallMultplMIDSvrOnASingleSys "Install multiple MID Servers on the same host computer. Multiple MID Servers can support each other with load balancing, as well as use domain separation. The number of MID Servers required is determined by factors like network policies, security restraints, and the reliability of the host computer.").
2. Locate the following lines in the file:  

       # OPTIONAL: Maximum Java Heap Size (in MB)
       wrapper.java.maxmemory=1024

3. Edit the memory allocation.
4. Remove the comment tag (#) from the memory allocation parameter.
5. Save the file.
6. Restart the MID Server service.
