Add Host

Use this procedure to add another host to the grid. By adding a new host to the grid, applications may scale out to this new host or new applications may be installed there.

It is safe to add hosts to a grid while the grid and existing applications are running and in use.

Note: 

In order to be able to add a host, the host has to be running an LCM Service so that LifeCycle Manager is able to communicate with it.

  1. In LifeCycle Manager, in the Applications tab of the left pane, double-click on the Grid Hosts node for your grid.
  2. In the Tasks tab of the right pane, click Add Host.
  3. On the Add a New Host to Grid window, enter the following:
    Host

    Select a new host to add to the grid.

    Internal Address

    Select the internal address of the host. This address will be used by the grid agents, registry, and nodes on this host, and to generate the host.ks.keystore that is used to establish trust between grid hosts (internal host-host trust).

    It is recommended to use the FQDN.

    External Address

    Enter the external address for the host. This address is used by the administrative router, default router and other grid routers to which clients will connect. It is used to generate the https.ks (SSL keystore) which is presented to clients when they connect to the grid via HTTPS (WS, REST, and so on).

    It is recommended to use the FQDN.

    Always recommended to be an FQDN (though no limitation prevents you using IP address) - This address is used by the Administrative Router, Default Router and other Grid routers to which clients will connect - This address is used to generate the https.ks (SSL keystore) which is presented to clients when they connect to the Grid via HTTPS (WS, REST, etc)

    Description

    Enter a description for this host.

    Grid Agent Port

    Enter the port number for the grid agent on this host. This port is used for configuration purposes. It must be accessible from the LifeCycle Manager server.

    JDK

    32 bit JDK

    Select the 32 bit JDK that the grid will use (Required for the Windows platform)

    64 bit JDK

    Select the 64 bit JDK that the grid will use

    Run host with 32 bit JDK

    Select this option to run the grid with the 32 bit JDK (Required for the Windows platform)

    Run host with 64 bit JDK

    Select this option to run the grid with the 64 bit JDK
