When deploying Confluence using .exe installer, it will come with a bundled JRE (JAVA). Sometimes, in order to upgrade the JAVA version, Confluence needs to switch from bundled JRE to user installed JAVA.

手順

1. Install JAVA in your machine (see Installing Java for Confluence)

2. Confluence を停止します。

3. Identify the name of the service that Confluence is installed as in Windows (Go to Control Panel > Administrative Tools > Services):
   
    In the above example, the service name is Confluence121213135538. 
4. コマンド ウィンドウを開きます ([スタート] > [cmd.exe] を選択)。 
5. cd to the bin directory of your Confluence instance (or the bin directory of your Tomcat installation if you are running Confluence EAR/WAR).

6. Run the following command for Confluence 5.8:

   
   

   tomcat8w //ES//<SERVICENAME>

   
   

    In the above example, it would be tomcat8w //ES//Confluence121213135538
   The Tomcat version number may be different if you are using an earlier version of Confluence. 

7. [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。
   
8. Uncheck the 'Use default'
9. Modify the 'Java Virtual Machine' to point at the jvm.dll of the installed JAVA in Step 1
   (e.g. Java Virtual Machine: C:\Program Files (x86)\Java\jdk1.8.0_66\jre\bin\server\jvm.dll or C:\Program Files (x86)\Java\jre1.8.0_66\bin\client\jvm.dll)
10. Click 'OK'
11. Confluence を起動します。
