9.5. Exporting a server snapshot
Copia collegamento

You can export the installation manager configuration used by your JBoss EAP server to an archive file. This file can be used to recreate the same server configuration using the jboss-eap-installation-manager tool. This feature ensures easy replication of your server setup in other environments. For information see exporting a server snapshot using the jboss-eap-installation-manager.

One compelling use case for this capability is when you encounter a technical issue and need to seek support from the JBoss EAP team. By sharing the exported archive file with the support team, they can recreate your server configuration precisely as it is in your environment. This ensures that the support team can replicate the issue you are facing and provide targeted assistance, ultimately expediting the resolution process. You can also provide more details about your environment by following the steps in the JDR tool documentation.

Procedure

  1. Launch the Management CLI: 

    EAP_HOME/bin/jboss-cli.sh
    Copy to Clipboard Toggle word wrap

  2. Export a server snapshot:

    1. Export a server snapshot in a stand-alone server: 

      standalone@localhost:9990 /] attachment save --operation=/core-service=installer:clone-export()
      Copy to Clipboard Toggle word wrap

    2. Export a server snapshot in a managed domain: 

      [domain@localhost:9990 /] attachment save --operation=/host=target-host/core-service=installer:clone-export()
      Copy to Clipboard Toggle word wrap
