uninstalls GlassFish Server software from specified hosts

Synopsis

    uninstall-node [--help]
    [--installdir as-install-parent]
    [--sshport ssh-port] [--sshuser ssh-user]
    [--sshkeyfile ssh-keyfile]
    [--force={false|true}]
    host-list

Description

The `uninstall-node` subcommand uninstalls GlassFish Server software from the hosts that are specified as the operand of the subcommand. This subcommand requires secure shell (SSH) to be configured on the host where the subcommand is run and on each host where the GlassFish Server software is being uninstalled.

Note:

This subcommand is equivalent to the uninstall-node-ssh(1) subcommand. To uninstall GlassFish Server software on hosts that use the Distributed Component Object Model (DCOM) remote protocol, use the uninstall-node-dcom(1) subcommand.

By default, if any node except the predefined node `localhost-`domain resides on any host from which GlassFish Server software is being uninstalled, the subcommand fails. To uninstall the GlassFish Server software from a host on which user-defined nodes reside, set the `--force` option to `true`. If the `--force` option is `true`, the subcommand removes the entire content of the parent of the base installation directory.

If a file under the parent of the base installation directory is open, the subcommand fails.

If multiple hosts are specified, the configuration of the following items must be the same on all hosts:

- Parent of the base installation directory for the GlassFish Server software

- SSH port

- SSH user

- SSH key file

The subcommand does not modify the configuration of the domain administration server (DAS).

This subcommand is supported in local mode only.

Options

`--help`
`-?`

  Displays the help text for the subcommand.

`--installdir`

  The absolute path to the parent of the base installation directory where the GlassFish Server software is installed on each host, for example, `/export/glassfish3/`.

  The user that is running this subcommand must have write access to the specified directory. Otherwise, an error occurs.

  The specified directory must contain the installation of the GlassFish Server software on the host. Otherwise, an error occurs.

  The default is the parent of the base installation directory of the GlassFish Server software on the host where this subcommand is run.

`--sshport`

  The port to use for SSH connections to the host where the GlassFish Server software is to be uninstalled. The default is 22.

`--sshuser`

  The user on the host where the GlassFish Server software is to be uninstalled that is to run the process for connecting through SSH to the host. The default is the user that is running this subcommand. To ensure that the DAS can read this user's SSH private key file, specify the user that is running the DAS process.

`--sshkeyfile`

  The absolute path to the SSH private key file for user that the `--sshuser` option specifies. This file is used for authentication to the `sshd` daemon on the host.

  The user that is running this subcommand must be able to reach the path to the key file and read the key file.

  The default is a key file in the user's `.ssh` directory. If multiple key files are found, the subcommand uses the following order of preference:

  1. `id_rsa`

  2. `id_dsa`

  3. `identity`

`--force`

  Specifies whether the subcommand uninstalls the GlassFish Server software from a host even if a user-defined node resides on the host. Possible values are as follows:

  `false`

    If a user-defined node resides on a host, the software is not uninstalled and the subcommand fails (default).

    If the `--force` option is `false`, the subcommand removes only the GlassFish Server software files. Other content if the parent of the base installation directory, such as configuration files, are not removed.

  `true`

    The subcommand uninstalls the GlassFish Server software from the host even if a user-defined node resides on the host.

    If the `--force` option is `true`, the subcommand removes the entire content of the parent of the base installation directory.

Operands

host-list

  A space-separated list of the names of the hosts from which the GlassFish Server software is to be uninstalled.

Examples

Example 1 Uninstalling GlassFish Server Software From the Default Location

  This example uninstalls GlassFish Server software on the hosts `sj03.example.com` and `sj04.example.com` from the default location.

      asadmin> uninstall-node sj03 sj04
      Successfully connected to gfuser@sj03.example.com using keyfile /home/gfuser
      /.ssh/id_rsa
      Successfully connected to gfuser@sj04.example.com using keyfile /home/gfuser
      /.ssh/id_rsa
      Command uninstall-node executed successfully.

Example 2 Forcibly Uninstalling GlassFish Server Software

  This example uninstalls GlassFish Server software on the host `sj02.example.com`.

  The software is uninstalled even if a user-defined node resides on the host. The entire content of the `/export/glassfish3` directory is removed.

  Some lines of output are omitted from this example for readability.

      asadmin> uninstall-node --force --installdir /export/glassfish3 sj02.example.com
      Successfully connected to gfuser@sj02.example.com using keyfile /home/gfuser
      /.ssh/id_rsa
      Force removing file /export/glassfish3/mq/lib/help/en/add_overrides.htm
      Force removing file /export/glassfish3/mq/lib/help/en/add_connfact.htm
      ...
      Force removing directory /export/glassfish3/glassfish/lib/appclient
      Force removing directory /export/glassfish3/glassfish/lib
      Force removing directory /export/glassfish3/glassfish
      Command uninstall-node executed successfully.
