Maintenance procedure for multiple cluster environment

In case of multiple cell+cluster environment i.e. WebSphere Portal Server Gold Availability Standard environment every cluster gets its own Release domain but the customization and community data is shared. As a result you can safely apply the major fixes that change the configuration stored in the release database.

Follow this procedure to update the multi cell environment

  • Change the IT Sprayer so that it stops forwarding requests to the one line of production

  • Once that is done you can update that line of production and during that time second line of production will service requests

  • Test the first line of production and once your satisfied you start the first line of production and reconfigure IP sprayer to forward request to first line of production

  • Follow similar procedure for all other lines of productions
