asadmin-stop-domain

asadmin-stop-domain(1AS)					   User Commands					  asadmin-stop-domain(1AS)

NAME

       asadmin-stop-domain, stop-domain - stops the given domain

SYNOPSIS

       stop-domain [--domaindir install_dir/domains][--terse=false] [--echo=false] [domain_name]

       stop-domain  stops the specified domain. If there is only one domain in the default domain directory (install_dir/domains), then no operand
       is required to stop the domain. However, if there is more than one domain, the domain operand must be specified. This command is  supported
       in local mode only.

OPTIONS

       --domaindir	       directory where the domain is to be stopped. If specified, path must be accessible in the filesystem. If not speci-
			       fied, the domainis stopped in the default install_dir/domains directory.

       --terse		       indicates that any output data must be very concise, typically avoiding human-friendly sentences and favoring well-
			       formatted data for consumption by a script. Default is false.

       --echo		       setting to true will echo the command line statement on the standard output. Default is false.

OPERANDS

       domain_name	       name of the domain. Must be a unique name.

       Example 1: Using stop-domain

       asadmin> stop-domain sampleDomain
       Stoping Domain sampleDomain, please wait
       Domain sampleDomain stopped
       Command stop-domain executed successfully

       Where: the sampleDomain domain in the default domains directory is stopped.

EXIT STATUS

       0		       command executed successfully

       1		       error in executing the command
