Description

The uninstall-node-ssh subcommand uninstalls Payara 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 Payara Server software is being uninstalled.

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

By default, if any node except the predefined node localhost-`domain resides on any host from which Payara Server software is being uninstalled, the subcommand fails. To uninstall the Payara 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 Payara 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

asadmin-options

Options for the asadmin utility. For information about these options, see the asadmin help page.

--help

-?

Displays the help text for the subcommand.

--installdir

The absolute path to the parent of the base installation directory where the Payara Server software is installed on each host, for example, /export/payara6/.
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 Payara Server software on the host. Otherwise, an error occurs.
The default is the parent of the base installation directory of the Payara Server software on the host where this subcommand is run.

--sshport

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

--sshuser

The user on the host where the Payara 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:

id_rsa
id_dsa
identity

--force

Specifies whether the subcommand uninstalls the Payara 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 Payara 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 Payara 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 Payara Server software is to be uninstalled.

Examples

Example 1 Uninstalling Payara Server Software From the Default Location

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

asadmin> uninstall-node-ssh 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-ssh executed successfully.

Example 2 Forcibly Uninstalling Payara Server Software

This example uninstalls Payara 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/payara6 directory is removed.

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

asadmin> uninstall-node-ssh --force --installdir /export/payara6 sj02.example.com
Successfully connected to gfuser@sj02.example.com using keyfile /home/gfuser
/.ssh/id_rsa
Force removing file /export/payara6/mq/lib/help/en/add_overrides.htm
Force removing file /export/payara6/mq/lib/help/en/add_connfact.htm
...
Force removing directory /export/payara6/glassfish/lib/appclient
Force removing directory /export/payara6/glassfish/lib
