Documentation

Environment

Release : 10.7.0

Component : EM, Webview, Workstation 

Resolution

Manual Steps to  introduce  AdoptOpenJDK:

1. Stop Enterprise Manager:

  • cd <EM_HOME>/bin
  • ./EMCtrl.sh stop

2. Stop WebView:

  • cd <EM_HOME>/bin
  • ./WVCtrl.sh stop

3. Copy the contents of the jre folder in the <EM_HOME> directory to a new folder jreBackup

4. Delete all the contents inside the jre folder in the <EM_HOME> directory

5. Download the JRE of AdoptOpenJDK (u222-b10) and put its contents to the jre folder in the <EM_HOME> directory

6. Start Enterprise Manager and WebView:

  • cd <EM_HOME>/bin
  • ./EMCtrl.sh start
  • cd <EM_HOME>/bin
  • ./WVCtrl.sh start

7. Verify that AdoptOpenJDK is being used by checking the logs:

  • In IntroscopeEnterpriseManager.log you should see something like the following:
    • 9/16/19 03:22:23.391 PM CEST [INFO] [main] [Manager] Introscope Enterprise Manager Release 10.7.0.220 (Build 994002)
    • 9/16/19 03:22:23.396 PM CEST [INFO] [main] [Manager] Using Java VM version "OpenJDK 64-Bit Server VM 1.8.0_222" from AdoptOpenJDK
  • In IntroscopeWebView.log you should see something like the following:
    • 9/16/19 03:23:34.127 PM CEST [INFO] [WebView] Introscope WebView Release 10.7.0.220 (Build 994002)
    • 9/16/19 03:23:34.128 PM CEST [INFO] [WebView] Using Java VM version "OpenJDK 64-Bit Server VM 1.8.0_222" from AdoptOpenJDK

8. If you have installed Workstation separately, follow the same process as above:

  • make sure Workstation is not running
  • create a backup of its jre folder
  • copy the contents of the JRE of AdoptOpenJDK into the jre folder of Workstation
  • start workstation

9. If you are accessing Workstation through Webstart and if you are using AdoptOpenJDK in the machine that you are accessing Workstation, then the Workstation will fail to start.
