asadmin-delete-instance
asadmin-delete-instance(1AS) User Commands asadmin-delete-instance(1AS)
NAME
delete-instance - deletes the instance that is not running.
SYNOPSIS
delete-instance [--user admin_user] [--password admin_password] [--host localhost] [--port 4848] [--local=false] [--domain domain_name]
[--passwordfile filename] [--secure|-s]instance_name
Use the delete-instance command to delete the instance that you specify. The delete-instance command can be run both locally and remotely.
To delete the instance locally, not requiring the administration server to be up and running, specify the --local option. To delete the
instance remotely, the administration server must be running on the hostname and port number specified. The user authenticates using the
password identified for the administration server. Additionally, the instance must already exist within the domain served by the adminis-
tration server. Use this command with discretion since it is destructive and there is no undo.
OPTIONS
--user administrative user associated for the instance.
--password administrative password corresponding to the administrative user.
--host host name of the machine hosting the administrative instance.
--port administrative port number associated with the administrative host.
--domain name of the domain.
--local determines if the command should delegate the request to administrative instance or run locally.
--passwordfile file containing passwords appropriate for the command (e.g., administrative instance).
--secure if true, SSL/TLS to communicate with the administrative instance.
OPERANDS
instance_name name of the instance to be deleted.
Example 1: Using delete-instance in local mode
asadmin> delete-instance --domain domain1 server1
Deleted Instance server1 successfully
Where: the server1 instance for the domain1 domain is deleted on the local machine.
Example 2: Using delete-instance in remote mode
asadmin> delete-instance --user admin --passwordfile passwords.txt --host localhost --port 4848 server1
Deleted Instance server1 successfully
Where: the server1 instance for the domain associated with the specified user, passwords in the password file, host, and port number is
deleted on the remote machine.
EXIT STATUS
0 command executed successfully
1 error in executing the command
