Managing Planned Outages

In a planned outage, you schedule a time when vFabric Web Server instances will be briefly unavailable so that you can perform maintenance on the instance, create cold backups, and so on.

  1. On the computer on which the vFabric Web Server instances are installed, log in as the root (Unix) or Administrator (Windows) user and stop all instances. For example, on Unix:

    prompt# cd /opt/vmware/vfabric-web-server/myserver/bin
    prompt# ./httpctl stop

    In the preceding example, the vFabric Web Server instance is located in the /opt/vmware/vfabric-web-server/myserver directory.

    The stop command forcibly ends all sessions. To specify that you want the Web Server instance to wait until all sessions end gracefully, use the gracefulstop command:

    prompt# ./httpdctl gracefulstop

    See Creating and Using vFabric Web Server Instances for additional details, such as Windows instructions.

  2. Perform any required maintenance on the instance, such as updating its configuration and creating a cold backup. While the Web Server instances are stopped, the content deployed to the instances is not available to users.

  3. If the Web Server instance is acting as a proxy or load balancer to one or more application server instances, such as tc Runtime instances, start them if they are not already running.

  4. Start the vFabric Web Server instances. For example:

    prompt# cd /opt/vmware/vfabric-web-server/myserver/bin
    prompt# ./httpctl start
