16 Command Line Reference

This chapter provides reference information on the use of the Message Queue command line administration utilities. It consists of the following sections:

Command Line Syntax

Message Queue command line utilities are shell commands. The name of the utility is a command and its subcommands or options are arguments passed to that command. There is no need for separate commands to start or quit the utility.

All the command line utilities share the following command syntax:

utilityName [subcommand] [commandArgument] [-optionName [optionArgument] ]...

where utilityName is one of the following:

  • imqbrokerd (Broker utility)

  • imqcmd (Command utility)

  • imqobjmgr (Object Manager utility)

  • imqdbmgr (Database Manager utility)

  • imqusermgr (User Manager utility)

  • imqbridgemgr (Bridge Manager utility)

  • imqsvcadmin (Service Administrator utility)

  • imqkeytool (Key Tool utility)

Subcommands and command-level arguments, if any, must precede all options and their arguments; the options themselves may appear in any order. All subcommands, command arguments, options, and option arguments are separated with spaces. If the value of an option argument contains a space, the entire value must be enclosed in quotation marks. (It is generally safest to enclose any attribute-value pair in quotation marks.)

The following command, which starts the default broker, is an example of a command line with no subcommand clause:

imqbrokerd

Here is a fuller example:

imqcmddestroy dst-t q-n myQueue-u admin-f-s

This command destroys a queue destination (destination type q) named myQueue. Authentication is performed on the user name admin; the command will prompt for a password. The command will be performed without prompting for confirmation (-f option) and in silent mode, without displaying any output (-s option).

Broker Utility

The Broker utility (imqbrokerd) starts a broker. Command line options override values in the broker configuration files, but only for the current broker session.

Table 16-1 shows the options to the imqbrokerd command and the configuration properties, if any, overridden by each option.

Table 16-1 Broker Utility Options

Option Description
-name instanceName

Instance name of broker

Multiple broker instances running on the same host must have different instance names.

Default value: imqbroker

Properties overridden: imq.instancename

-port portNumber

Port number for broker's Port Mapper

Message Queue clients use this port number to connect to the broker. Multiple broker instances running on the same host must have different Port Mapper port numbers.

Default value: 7676

Properties overridden: imq.portmapper.port

-cluster broker1 [,broker2]...

Connect brokers into clusterFoot 1 

The specified brokers are merged with the list in the imq.cluster.brokerlist property. Each broker argument has one of the forms

  • hostName:portNumber

  • hostName

  • :portNumber

If hostName is omitted, the default value is localhost; if portNumber is omitted, the default value is 7676.

Literal IP addresses as host names: You can use a literal IPv4 or IPv6 address as a host name. If you use a literal IPv6 address, its format must conform to RFC2732, Format for Literal IPv6 Addresses in URL's.

Properties overridden: imq.cluster.brokerlist

-Dproperty=value

Set configuration property

See Broker Properties Reference for information about broker configuration properties.

Caution: Be careful to check the spelling and formatting of properties set with this option. Incorrect values will be ignored without notification or warning.

Properties overridden: Corresponding property in instance configuration file

-reset props

Reset configuration properties

Replaces the broker's existing instance configuration file config.properties with an empty file; all properties assume their default values.

Properties overridden: None

-reset store

Reset persistent data store

Clears all persistent data from the data store (including persistent messages, durable subscriptions, and transaction information), allowing you to start the broker instance with a clean slate. To prevent the persistent store from being reset on subsequent restarts, restart the broker instance without the -reset option.

To clear only persistent messages or durable subscriptions, use -reset messages or -reset durables instead.

Properties overridden: None

-reset messages

Clear persistent messages from data store

Properties overridden: None

-reset durables

Clear durable subscriptions from data store

Properties overridden: None

-reset takeover-then-exit

Clear any takeover locks and then exit.

If a broker fails before completing the takeover of another broker's store, the failed broker retains a takeover lock even though it is not running. Use -reset takeover-then-exit to cause the failed broker to initiate startup, release the takeover lock, and then exit without actually starting up.

Properties overridden: None

-backup fileName

Back up configuration change record to fileFootref 1

See Managing a Conventional Cluster's Configuration Change Record for more information.

Properties overridden: None

-restore fileName

Restore configuration change record from backup fileFootref 1

The backup file must have been previously created using the -backup option.

Footnote 3 Any other options specified on the command line are ignored.

Command Utility

The Command utility (imqcmd) is used for managing brokers, connection services, connections, physical destinations, durable subscriptions, and transactions.

All imqcmd commands must include a subcommand (except those using the -v or -h option to display product version information or usage help, respectively). The possible subcommands are listed in Table 16-2 and described in detail in the corresponding sections below. In addition, each imqcmd subcommand supports the general options shown in General Command Utility Options.

Note:

The -u userName option (and corresponding password) is required except when using the -v or -h option. Also if a subcommand accepts a broker address (-b option) and no host name or port number is specified, the values localhost and 7676 are assumed by default.

Broker Management

The Command utility cannot be used to start a broker; use the Broker utility (imqbrokerd) instead. Once the broker is started, you can use the imqcmd subcommands listed in Table 16-4 to manage and control it.

Table 16-4 Command Utility Subcommands for Broker Management

Syntax Description
shutdown bkr [-b hostName:portNumber]
 [-time nSeconds]
 [-nofailover]

Shut down broker

The -time option specifies the interval, in seconds, to wait before shutting down the broker. (The broker will not block, but will return immediately from the delayed shutdown request.) During the shutdown interval, the broker will not accept any new jms connections; admin connections will be accepted, and existing jms connections will continue to operate. A broker belonging to an enhanced cluster will not attempt to take over for any other broker during the shutdown interval.

The -nofailover option indicates that no other broker is to take over the persistent data of the one being shut down. Foot 1 

restart bkr [-b hostName:portNumber]

Restart broker

Shuts down the broker and then restarts it using the same options specified when it was originally started.

pause bkr [-b hostName:portNumber]

Pause broker

See Pausing and Resuming a Broker for more information.

quiesce bkr [-b hostName:portNumber]

Quiesce broker

The broker will stop accepting new connections; existing connections will continue to operate.

unquiesce bkr [-b hostName:portNumber]

Unquiesce broker

The broker will resume accepting new connections, returning to normal operation.

resume bkr [-b hostName:portNumber]

Resume broker

takeover bkr 
 -n brokerID
 [-f]

Initiate broker takeover Footref 1

Before taking over a broker, you should first shut it down manually using the shutdown bkr subcommand with the -nofailover option. If the specified broker appears to be still running, takeover bkr will display a confirmation message (Do you want to take over for this broker?). The -f option suppresses this message and initiates the takeover unconditionally.

Note: The takeover bkr subcommand is intended only for use in failed-takeover situations. You should use it only as a last resort, and not as a general way of forcibly taking over a running broker.

update bkr [-b hostName:portNumber]
 -o property1=value1
 [-o property2=value2]...

Set broker properties

See Broker Properties Reference for information on broker properties.

query bkr
 -b hostName:portNumber

List broker property values

For brokers belonging to a cluster, also lists cluster properties such as broker list, master broker (for conventional clusters), and cluster identifier (for enhanced clusters).

list bkr

List brokers in cluster

metrics bkr [-b hostName:portNumber]
 [-m metricType]
 [-int interval]
 [-msp numSamples]

Display broker metrics

The -m option specifies the type of metrics to display:

  • ttl: Messages and packets flowing into and out of the broker

  • rts: Rate of flow of messages and packets into and out of the broker per second

  • cxn: Connections, virtual memory heap, and threads

Default value: ttl.

The -int option specifies the interval, in seconds, at which to display metrics. Default value: 5.

The -msp option specifies the number of samples to display. Default value: Unlimited (infinite).

reload cls

Reload cluster configurationFootref 1

Forces all persistent information to be brought up to date.

changemaster cls
 -o imq.cluster.masterbroker=newMaster

Change the master broker in a conventional cluster with master broker.

This command must be run on the current master broker.

The value newMaster has the form hostName:portNumber, where hostName and portNumber are is its Port Mapper host name and port number, respectively.

Literal IP addresses as host names: You can use a literal IPv4 or IPv6 address as a host name. If you use a literal IPv6 address, its format must conform to RFC2732, Format for Literal IPv6 Addresses in URL's.

Database Manager Utility

The Database Manager utility (imqdbmgr) sets up the database schema for a JDBC-based data store. You can also use it to delete Message Queue database tables that have become corrupted, change the database, display information about the database, convert a standalone database for use in an enhanced broker cluster, or back up and restore a highly-available database. Table 16-13 lists the imqdbmgr subcommands.

Note:

When using a cluster configuration file to simplify management of the properties for a cluster of brokers, make sure to run imqdbmgr with the -D option to specify the location of the cluster configuration file; for example:

imqdbmgr -Dimq.cluster.url=location-of-cluster-configuration-file ...

Table 16-13 Database Manager Subcommands

Subcommand Description
create all

Create new database and persistent data store schema

Used on embedded database systems. The broker property imq.persist.jdbc.vendorName.createdburl must be specified.

create tbl

Create persistent data store schema for existing database

Used on external database systems.

For brokers belonging to an enhanced broker cluster (imq.cluster.ha = true), the schema created is for the cluster's shared data store, in accordance with the database vendor identified by the broker's imq.persist.jdbc.dbVendor property. If imq.cluster.ha = false, the schema is for the individual broker's standalone data store. Since the two types of data store can coexist in the same database, they are distinguished by appending a suffix to all table names:

  • C clusterID: Shared data store

  • S brokerID: Standalone data store

delete tbl

Delete Message Queue database tables from current data store

delete oldtbl

Delete Message Queue database tables from earlier-version data store

Used after the data store has been automatically migrated to the current version of Message Queue.

recreate tbl

Re-create persistent store schema

Deletes all existing Message Queue database tables from the current persistent store and then re-creates the schema.

query

Display information about the data store

upgrade hastore

Upgrade standalone data store to shared data store

backup

Back up JDBC-based data store to backup files

restore

Restore JDBC-based data store from backup files

remove bkr

User Manager Utility

The User Manager utility (imqusermgr) is used for populating or editing a flat-file user repository. The utility must be run on the same host where the broker is installed; if a broker-specific user repository does not yet exist, you must first start up the corresponding broker instance in order to create it. You will also need the appropriate permissions to write to the repository: on the Solaris or Linux platforms, this means you must be either the root user or the user who originally created the broker instance.

Table 16-15 lists the subcommands available with the imqusermgr command. In all cases, the -i option specifies the instance name of the broker to whose user repository the command applies; if not specified, the default name imqbroker is assumed.

Table 16-15 User Manager Subcommands

Syntax Description
add [-i instanceName]
 -u userName -p password
 [-g  group]

Add user and password to repository

The optional -g option specifies a group to which to assign this user:

  • admin

  • user

  • anonymous

delete [-i instanceName]
 -u userName

Delete user from repository

update [-i instanceName]
 -u userName -p password

update [-i instanceName]
 -u userName -a activeStatus

update [-i instanceName]
 -u userName -p password
 -a activeStatus

Set user's password or active status (or both)

The -a option takes a boolean value specifying whether to make the user active (true) or inactive (false). An inactive status means that the user entry remains in the user repository, but the user will not be authenticated, even if using the correct password.

Default value: true.

list [-i instanceName]
 [-u userName]

Display user information

If no user name is specified, all users in the repository are listed.


In addition, the options listed in Table 16-16 can be applied to any subcommand of the imqusermgr command.

Bridge Manager Utility

The Bridge Manager utility (imqbridgemgr) is used to manage the bridges configured for a broker, including the links within bridge types that support links. The basic syntax of imqbridgemgr is:

imqbridgemgr subcommand commandArgument [ options ]
imqbridgemgr -h | -help
imqbridgemgr -H | -Help
imqbridgemgr -v | -version

Table 16-17 lists the imqbridgemgr subcommands for general bridge management, Table 16-18 lists the imqbridgemgr subcommands for link management, which are applicable only to bridge types that support links, and Table 16-19 lists the imqbridgemgr options.

Table 16-17 Bridge Manager Subcommands for Bridge Management

Subcommand Description
list bridge

Lists the bridges specified by the command options provided. For each bridge, the bridge name, type and state are displayed.

pause bridge

Pauses the bridges specified by the command options provided if the bridge type supports this subcommand.

Attempting to pause a bridge that is stopped generates an error, and attempting to pause a bridge that is already paused has no effect.
