NAME

imqcmd - manage Message Queue brokers
 

SYNOPSIS

/usr/bin/imqcmd subcommand argument [option...] 

/usr/bin/imqcmd [-h | -H]

/usr/bin/imqcmd -v

DESCRIPTION

imqcmd manages the Message Queue broker, including resources such as connection services, physical destinations, durable subscriptions, and transactions. The utility provides a number of subcommands for managing these resources.

imqcmd supports many subcommands. Basic connection and authentication is required for the execution of every imqcmd subcommand. Use the -secure option to specify secure connections. Subcommands and their corresponding arguments and options follow the imqcmd command on the command line. See USAGE and OPTIONS.  

OPTIONS

The following options are supported:

-b hostName:port

Specify the name of the host on which the broker instance is running and the port number it is using.

The default value is localhost:7676. If you do not specify the -b option, imqcmd uses the default.

To specify port only, use: -b :7878. This is equivalent to -b localhost:7878

To specify name only, use: -b somehost. This is equivalent to -b somehost:7676.

-c clientID

Specify the ID of the durable subscriber to a topic.

-d topicName

Specify the name of the topic.

Use this option with the list dur and destroy dur subcommands.

-f

Perform action without user confirmation.

Use this option with any subcommand.

-h

Display usage help. Execute nothing else on the command line.

-H

Display usage help, attribute list, and examples. Execute nothing else on the command line.

-int interval

Specify the interval, in seconds, at which the metrics bkr, metrics dst, and metrics svc subcommands display metrics output.

Use this option with the metrics subcommand.

-javahome

Specify an alternate Java 2 compatible runtime to use.

-m metricType

Specify the type of metric information to diplay.

Use this option with the metrics bkr, metrics dst, and metrics svc subcommands. The value of metricType depends on whether the metrics are generated for a destination, a service, or a broker.

Use one of the following values to specify metricType:

ttl

Total of messages in and out of the broker (default)

rts

Provides the same information as ttl, but specifies the number of messages per second

cxn

Connections, virtual memory heap, threads

The following command displays connection, VM heap, and threads metric information for the default broker instance (localhost:7676) every five seconds:

imqcmd metrics bkr -m cxn -int 5

-msp numSamples

Specify the number of samples the metrics bkr, metrics dst, and metrics svc subcommands display in the metrics output.

-n argumentName

Specify the name of the subcommand argument. Depending on the subcommand, this might be the name of a service, a physical destination, a durable subscription, or a transaction ID.

-o attribute=value

Specify the value of an attribute. Depending on the subcommand argument, this might be the attribute of a broker, service, or destination.

-p password

Specify the administrator password.

This option is deprecated. Use the -passfile option instead.

-passfile

Specify the administrator password.

-pst pauseType

Specify whether producers, consumers, or both are paused when pausing a destination.

Use this option with the pause dst subcommand. Use one of the following values:

CONSUMERS

Pause delivery of messages to consumers.

PRODUCERS

Pause delivery of messages from producers.

ALL

Pause delivery of messages to consumers and from producers.

If the -pst option is not specified, pauses both consumers and producers (the equivalent of -pst ALL).

-rtm timeout

Specify the timeout period in seconds of an imqcmd subcommand. The default value is 10.

-rtr numRetries

Specify the number of retries attempted after an imqcmd subcommand times out.

The default value is 5.

-s

Silent mode. No output is displayed.

Use this option with any subcommand.

-secure

Specify a secure administration connection to the broker instance. You must first configure the broker to enable a secure connection service.

Use this option whenever you want a secure communication with the broker.

-svn serviceName

Specify the service for which the connections are listed.

Use this option with the list cxn subcommand.

-t destinationType

Specify the type of a destination: t (topic) or q (queue).

-tmp

Include temporary destinations when listing destinations using the list dst subcommand.

-u name

Specify the administrator user name.

If you omit this value, you are prompted for it.

-v

Display version information. Execute nothing else on the command line.
