When running Confluence as a service on Windows it does not recognize the system properties set in setenv.bat and instead loads them from Tomcat. These are instructions on how to modify these properties.

ソリューション

1. Identify the name of the service that Confluence is installed as in Windows ( Control Panel > Administrative Tools > Services ):
   
   In the above example, the SERVICENAME is: JIRA030908110721 (this is a JIRA screenshot, but the same applies to Confluence)
2. Start >> Run >> type in 'cmd' >> Enter でコマンド ウィンドウを開きます。
3. cd to the bin directory of your Confluence instance

4. Type and run the following (change tomcat9w to whatever version you are using):

   tomcat9w //ES//<Your_Service_Name>

5. Java タブをクリックして、現在の起動オプションの一覧を表示します。
   
   1. You can set Initial and the maximum memory allocation here via Initial/Maximum memory pool
   2. You can add System Properties to the Java Options field (one per line)
