lists \{product---name} instances in a domain

Synopsis

asadmin [asadmin-options] list-instances [--help]
[--timeoutmsec timeout]
[--long={false|true} | --nostatus={false|true}]
[--standaloneonly={false|true} | target]

Description

The list-instances subcommand lists \{product---name} instances in a domain. The list can be filtered by cluster, instance, node, or configuration.

The subcommand displays every \{product---name} instance in the specified target, regardless of how each instance was created. For example, this subcommand lists instances that were created by using the create-instance(1) subcommand and by using the create-local-instance(1) subcommand.

By default, the subcommand indicates whether each instance that is listed is running. Options of this subcommand control the information that is displayed for each instance.

This subcommand is supported in remote mode only.

Options

asadmin-options

Options for the asadmin utility. For information about these options, see the asadmin(1M) help page.

--help

-?

Displays the help text for the subcommand.

--timeoutmsec

The time limit in milliseconds for determining the status of instances. The default is 2,000, which is equivalent to 2 seconds.

--long

-l

Specifies whether detailed information is displayed for each instance that is listed.
The --long option and --nostatus option are mutually exclusive. If both options are specified in the same command, an error occurs.
Valid values are as follows:

true

The following details are displayed for each instance that is listed:

The name of the instance
The name of the host where the instance’s node resides
The HTTP port on which the instance listens for administration requests
The process identifier (PID) of the instance process or -1 if the instance is not running
The name of the cluster of which the instance is a member, if any
The state of the instance, which is running or not running
When an instance is listed, some configuration changes in the domain administration server (DAS) for the instance might not have been applied to the instance itself. In this situation, the commands that are required to apply the changes are listed adjacent to the state of the instance. The maximum number of commands that are listed for an instance is 10.

false

Only the name of the instance and an indication of whether the instance is running are displayed (default). The length of time that the instance has been running is not displayed.

--nostatus

Specifies whether information about whether instances are running is suppressed.
The --long option and --nostatus option are mutually exclusive. If both options are specified in the same command, an error occurs.
Valid values are as follows:

true: Information about whether instances are running is suppressed. Only the name of each instance is displayed.
false: Information about whether instances are running is displayed (default).

--standaloneonly

Specifies whether only standalone instances are listed.
The --standaloneonly option and the target operand and are mutually exclusive. If both the --standaloneonly option and the target operand are specified in the same command, an error occurs.
Valid values are as follows:

true: Only standalone instances are listed.
false: All instances in the specified target are listed (default).

Operands

target

Filters the list of \{product---name} instances by specifying the target for which instances are listed.
The target operand and the --standaloneonly option are mutually exclusive. If both the target operand and the --standaloneonly option are specified in the same command, an error occurs.
Valid values are as follows:

domain: Lists all instances in the domain (default).
cluster-name: Lists the instances that are members of the specified cluster.
instance-name: Lists only the specified instance.
node-name: Lists the instances that reside on the specified node.
configuration-name: Lists all instances whose configuration is defined by the specified named configuration.

Examples

Example 1 Listing Basic Information About All \{product---name} Instances in a Domain

This example lists the name and status of all \{product---name} instances in the current domain.

asadmin> list-instances
pmd-i-sj02 running
yml-i-sj02 running
pmd-i-sj01 running
yml-i-sj01 running
pmdsa1 not running

Command list-instances executed successfully.

Example 2 Listing Detailed Information About All \{product---name} Instances in a Domain

This example lists detailed information about all \{product---name} instances in the current domain.

asadmin> list-instances --long=true
NAME        HOST       PORT   PID    CLUSTER     STATE
pmd-i-sj01  sj01       24848  31310  pmdcluster   running
yml-i-sj01  sj01       24849  25355  ymlcluster   running
pmdsa1      localhost  24848  -1     ---          not running

Command list-instances executed successfully.

Example 3 Displaying the Status of an Instance

This example displays status of the instance pmd-i-sj01, which is running.

asadmin> list-instances pmd-i-sj01
pmd-i-sj01 running
Command list-instances executed successfully.

Example 4 Listing Only Standalone Instances in a Domain

This example lists only the standalone instances in the current domain.

asadmin> list-instances --standaloneonly=true
pmdsa1 not running
Command list-instances executed successfully.

Exit Status

0: command executed successfully
1: error in executing the command
