17 Broker Properties Reference

This chapter provides reference information about configuration properties for a message broker. It consists of the following sections:

Connection Properties

Table 17-1 lists the broker properties related to connection services.

Table 17-1 Broker Connection Properties

Property Type Default Value Description

imq.brokerid

String

None

Broker identifier

For brokers using a shared JDBC-based data store, this string is appended to the names of all database tables to identify each table with a particular broker.

Must be a unique alphanumeric string of no more than n - 13 characters, where n is the maximum table name length allowed by the database.

This property is unnecessary for an embedded database or a standalone database which stores data for only one broker instance.

Note: For enhanced broker clusters (imq.cluster.ha = true), database table names also use the imq.cluster.clusterid property (see Table 17-14).

imq.service.activelistFoot 1 

String

jms,admin

List of connection services to be activated at broker startup, separated by commas

See Table 6-1 under Configuring Connection Services for the names of the available connection services.

imq.hostname

String

All available IP addresses

Default host name or IP address for all connection services

imq.portmapper.hostname

String

None

Host name or IP address of Port Mapper

If specified, overrides imq.hostname. This might be necessary, for instance, if the broker's host computer has more than one network interface card installed.

imq.portmapper.portFoot 2 

Integer

7676

Port number of Port Mapper

Note: If multiple broker instances are running on the same host, each must be assigned a unique Port Mapper port.

imq.serviceName.protocolType.hostnameFoot 3 

String

None

Host name or IP address for connection service

If specified, overrides imq.hostname for the designated connection service. This might be necessary, for instance, if the broker's host computer has more than one network interface card installed.

imq.serviceName.protocolType.portFootref 3

Integer

0

Port number for connection service

A value of 0 specifies that the port number should be allocated dynamically by the Port Mapper. You might need to set a different value, for instance, to specify a static port number for connecting to the broker through a firewall.

imq.portmapper.backlog

Integer

50

Maximum number of pending Port Mapper requests in operating system backlog

imq.serviceName.threadpool_modelFoot 4 

String

dedicated

Threading model for thread pool management:

  • dedicated: Two dedicated threads per connection, one for incoming and one for outgoing messages

  • shared: Connections processed by shared thread when sending or receiving messages

     

The dedicated model limits the number of connections that can be supported, but provides higher performance; the shared model increases the number of possible connections, but at the cost of lower performance because of the additional overhead needed for thread management.

imq.serviceName.min_threads

Integer

jms: 10ssljms: 10httpjms: 10 httpsjms: 10 admin: 4ssladmin: 4

Minimum number of threads maintained in connection service's thread pool

When the number of available threads exceeds this threshold, threads will be shut down as they become free until the minimum is reached.

The default value varies by connection service, as shown.

imq.serviceName.max_threads

Integer

jms: 1000ssljms: 500httpjms: 500httpsjms : 500admin: 10ssladmin: 10

Number of threads beyond which no new threads are added to the thread pool for use by the named connection service

Must be greater than 0 and greater than the value of imq.serviceName.min_threads.

The default value varies by connection service, as shown.

imq.shared.connectionMonitor_limitFoot 5 

Integer

Solaris: 512Linux: 512Windows: 64

Maximum number of connections monitored by a distributor thread

The system allocates enough distributor threads to monitor all connections. The smaller the value of this property, the faster threads can be assigned to active connections. A value of -1 denotes an unlimited number of connections per thread.

The default value varies by operating-system platform, as shown.

imq.ping.interval

Integer

120

Interval, in seconds, at which to test connection between client and broker

A value of 0 or -1 disables periodic testing of the connection.


Footnote 1 Must have the same value for all brokers in an enhanced cluster.

Footnote 2 Can be used with imqcmd update bkr command

Footnote 3 jms, ssljms, admin, and ssladmin services only; see HTTP/HTTPS Support for information on configuring the httpjms and httpsjms services

Footnote 4 jms and admin services only

Footnote 5 Shared threading model only

Routing and Delivery Properties

This section includes the following tables:

  • Table 17-2 lists the broker properties related to routing and delivery services

  • Table 17-3 lists the broker properties that configure the automatic creation of destinations

  • Table 17-4 lists the broker properties that configure the administrative creation of destinations

Table 17-2 Broker Routing and Delivery Properties

Property Type Default Value Description

imq.system.max_countFoot 1 

Integer

-1

Maximum number of messages held by broker

A value of -1 denotes an unlimited message count.

imq.system.max_sizeFootref 1

String

-1

Maximum total size of messages held by broker

The value may be expressed in bytes, kilobytes, or megabytes, using the following suffixes:

  • b: Bytes

  • k: Kilobytes (1024 bytes)

  • m: Megabytes (1024 × 1024 = 1,048,576 bytes)

     

An unsuffixed value is expressed in bytes; a value of -1 denotes an unlimited message capacity.

     

Examples:

  • 1600: 1600 bytes

  • 1600b: 1600 bytes

  • 16k: 16 kilobytes (= 16,384 bytes)

  • 16m: 16 megabytes (= 16,777,216 bytes)

  • -1: No limit

imq.message.max_sizeFootref 1

String

70m

Maximum size of a single message body

The syntax is the same as for imq.system.max_size (see above).

imq.message.expiration.interval

Integer

60

Interval, in seconds, at which expired messages are removed

imq.resourceState.threshold

Integer

green: 0yellow: 80orange: 90red: 98

Percent utilization at which memory resource state is triggered (where resourceState is green, yellow, orange, or red)

imq.resourceState.count

Integer

green: 5000yellow: 500orange: 50red: 0

Maximum number of incoming messages allowed in a batch before checking whether memory resource state threshold has been reached (where resourceState is green, yellow, orange , or red)

This limit throttles back message producers as system memory becomes increasingly scarce.

imq.destination.DMQ.truncateBodyFootref 1

Boolean

false

Remove message body before storing in dead message queue?

If true, only the message header and property data will be saved.

imq.transaction.autorollback

Boolean

false

Automatically roll back distributed transactions left in prepared state at broker startup?

If false, transactions must be manually committed or rolled back using the Command utility (imqcmd).

imq.transaction.producer.maxNumMsgs

Integer

1000

The maximum number of messages that a producer can process in a single transaction. It is recommended that the value be less than 5000 to prevent the exhausting of resources.

imq.transaction.consumer.maxNumMsgs

Integer

100

The maximum number of messages that a consumer can process in a single transaction. It is recommended that the value be less than 1000 to prevent the exhausting of resources.


Footnote 1 Can be used with imqcmd update bkr command

This table lists properties that configure the automatic creation of destinations.

Table 17-3 Broker Properties for Auto-Created Destinations

Property Type Default Value Description

imq.autocreate.queueFoot 1 ,Foot 2 

Boolean

true

Allow auto-creation of queue destinations?

imq.autocreate.topicFoot 3 

Boolean

true

Allow auto-creation of topic destinations?

imq.autocreate.reaptime

Integer

120 seconds

The delay, in seconds. before which auto-created destinations are removed from the system when they no longer have consumers nor contain messages, . A smaller value means that memory reclamation takes place more often.

imq.autocreate.destination.maxNumMsgs

Integer

100000

Maximum number of unconsumed messages

A value of -1 denotes an unlimited number of messages.

Note: When flow control is in effect (imq.autocreate.destination.limitBehavior = FLOW_CONTROL), it is possible for the specified message limit to be exceeded because the broker cannot react quickly enough to stop the flow of incoming messages. In such cases, the value specified for imq.autocreate.destination.maxNumMsgs serves as merely a hint for the broker rather than a strictly enforced limit. However, if the number of unconsumed messages would exceed imq.system.max_count, the broker generates a ResourceAllocationException indicating that the destination is full and rejecting new messages.

imq.autocreate.destination.maxBytesPerMsg

String

10k

Maximum size, in bytes, of any single message

The value may be expressed in bytes, kilobytes, or megabytes, using the following suffixes:

  • b: Bytes

  • k: Kilobytes (1024 bytes)

  • m: Megabytes (1024 × 1024 = 1,048,576 bytes)

     

An unsuffixed value is expressed in bytes; a value of -1 denotes an unlimited message size.

     

Examples:

  • 1600: 1600 bytes

  • 1600b: 1600 bytes

  • 16k: 16 kilobytes (= 16,384 bytes)

  • 16m: 16 megabytes (= 16,777,216 bytes)

  • -1: No limit

imq.autocreate.destination.maxTotalMsgBytes

String

10m

Maximum total memory, in bytes, for unconsumed messages

The syntax is the same as for imq.autocreate.destination.maxBytesPerMsg (see above).

imq.autocreate.destination.limitBehavior

String

REJECT_NEWEST

Broker behavior when memory-limit threshold reached:

  • FLOW_CONTROL: Slow down producers

  • REMOVE_OLDEST: Throw out oldest messages

  • REMOVE_LOW_PRIORITY: Throw out lowest-priority messages according to age; no notification to producing client

  • REJECT_NEWEST: Reject newest messages; notify producing client with an exception only if message is persistent

When FLOW_CONTROL is specified, it is still possible for the number of messages to exceed imq.system.max_count. In this situation, the broker generates a ResourceAllocationException indicating that the destination is full and rejecting new messages.

     

If the value is REMOVE_OLDEST or REMOVE_LOW_PRIORITY and the imq.autocreate.destination.useDMQ property is true, excess messages are moved to the dead message queue.

imq.autocreate.destination.maxNumProducers

Integer

100

Maximum number of message producers for destination

When this limit is reached, no new producers can be created. A value of -1 denotes an unlimited number of producers.

imq.autocreate.queue.maxNumActiveConsumersFootref 2

Integer

-1

Maximum number of active message consumers in load-balanced delivery from queue destination

A value of -1 denotes an unlimited number of consumers.

imq.autocreate.queue.maxNumBackupConsumersFootref 2

Integer

0

Maximum number of backup message consumers in load-balanced delivery from queue destination

A value of -1 denotes an unlimited number of consumers.

imq.autocreate.queue.consumerFlowLimitFootref 2

Integer

1000

Maximum number of messages delivered to queue consumer in a single batch

In load-balanced queue delivery, this is the initial number of queued messages routed to active consumers before load balancing begins. A destination consumer can override this limit by specifying a lower value on a connection.

A value of 0 or -1 denotes an unlimited number of messages.

imq.autocreate.topic.consumerFlowLimitFootref 3

Integer

1000

Maximum number of messages delivered to topic consumer in a single batch

A value of 0 or -1 denotes an unlimited number of messages.

Not used when the JMS resource adapter, jmsra, is used to consume messages in a GlassFish Server cluster.

imq.autocreate.topic.sharedConsumerFlowLimitFootref 3

Integer

5

Maximum number of messages delivered to topic consumer in a single batch when the JMS resource adapter, jmsra, is used to consume messages in a GlassFish Server cluster

A value of 0 or -1 denotes an unlimited number of messages.

imq.autocreate.destination.isLocalOnly

Boolean

false

Local delivery only?

This property applies only to destinations in broker clusters, and cannot be changed once the destination has been created. If true, the destination is not replicated on other brokers and is limited to delivering messages only to local consumers (those connected to the broker on which the destination is created).

imq.autocreate.queue.localDeliveryPreferredFootref 2

Boolean

false

Local delivery preferred?

This property applies only to load-balanced queue delivery in broker clusters. If true, messages will be delivered to remote consumers only if there are no consumers on the local broker; the destination must not be restricted to local-only delivery (imq.autocreate.destination.isLocalOnly must be false).

imq.autocreate.destination.useDMQ

Boolean

true

Send dead messages to dead message queue?

If false, dead messages will simply be discarded.

validateXMLSchemaEnabled

Boolean

false

XML schema validation is enabled?

If set to false or not set, then XML schema validation is not enabled for the destination.

XMLSchemaURIList

String

null

Space separated list of XML schema document (XSD) URI strings

The URIs point to the location of one or more XSDs to use for XML schema validation, if enabled.

Use double quotes around this value if multiple URIs are specified.

Example:

"http://foo/flap.xsd http://test.com/test.xsd"

If this property is not set or null and XML validation is enabled, XML validation is performed using a DTD specified in the XML document.

reloadXMLSchemaOnFailure

Boolean

false

Reload XML schema on failure enabled?

If set to false or not set, then the schema is not reloaded if validation fails.


Footnote 1 Can be used with imqcmd update bkr command

Footnote 2 Queue destinations only

Footnote 3 Topic destinations only

This table lists properties that apply to all administratively created destinations. They cannot be configured on individual administratively created destinations.

Table 17-4 Broker Properties for Admin-Created Destinations

Property Type Default Value Description

imq.admincreate.topic.sharedConsumerFlowLimit

Integer

5

Maximum number of messages delivered to topic consumer in a single batch when the JMS resource adapter, jmsra, is used to consume messages in a GlassFish Server cluster

A value of 0 or -1 denotes an unlimited number of messages.


Persistence Properties

Message Queue supports both file-based and JDBC-based persistence modules. The broker property imq.persist.store (Table 17-5) specifies which module to use. The following sections describe the broker configuration properties for the two modules.

Table 17-5 Global Broker Persistence Property

Property Type Default Value Description

imq.persist.store

String

file

Module used for persistent data storage:

  • file: File-based persistence

  • jdbc: JDBC-based persistence

Must be set to jdbc for enhanced broker clusters (imq.cluster.ha = true).


File-Based Persistence Properties

Table 17-6 lists the broker properties related to file-based persistence.

Table 17-6 Broker Properties for File-Based Persistence

Property Type Default Value Description

imq.persist.file.message.max_record_size

String

1m

Maximum-size message to add to message storage file

Any message exceeding this size will be stored in a separate file of its own.

     

The value may be expressed in bytes, kilobytes, or megabytes, using the following suffixes:

  • b: Bytes

  • k: Kilobytes (1024 bytes)

  • m: Megabytes (1024 × 1024 = 1,048,576 bytes)

An unsuffixed value is expressed in bytes.

     

Examples:

  • 1600: 1600 bytes

  • 1600b: 1600 bytes

  • 16k: 16 kilobytes (= 16,384 bytes)

  • 16m: 16 megabytes (= 16,777,216 bytes)

imq.persist.file.destination.message.filepool.limit

Integer

100

Maximum number of free files available for reuse in destination file pool

Free files in excess of this limit will be deleted. The broker will create and delete additional files in excess of the limit as needed.

The higher the limit, the faster the broker can process persistent data.

imq.persist.file.message.filepool.cleanratio

Integer

0

Percentage of files in free file pools to be maintained in a clean (empty) state

The higher this value, the less disk space is required for the file pool, but the more overhead is needed to clean files during operation.

imq.persist.file.message.cleanup

Boolean

false

Clean up files in free file pools on shutdown?

Setting this property to true saves disk space for the file store, but slows broker shutdown.

imq.persist.file.sync.enabled

Boolean

false

Synchronize in-memory state with physical storage device?

Setting this property to true eliminates data loss due to system crashes, but at a cost in performance.

Note: If running Oracle Solaris Cluster and its Data Service for Message Queue, set this property to true for brokers on all cluster nodes.

imq.persist.file.transaction.memorymappedfile.enabled

Boolean

true

Use memory-mapped file to store transaction data?

Setting this property to true improves performance at the cost of increased memory usage. Set to false for file systems that do not support memory-mapped files.


File-Based Persistence Properties for Transaction Logging

Table 17-7 lists the file-based persistence properties for the transaction logging mechanism.

Table 17-7 Broker Properties for File-Based Persistence Using the Transaction Logging Mechanism

Property Type Default Value Description

imq.persist.file.newTxnLog.enabled

Boolean

false

Enables the transaction logging mechanism. For information about this mechanism, see Optimizing File-Based Transaction Persistence.

imq.persist.file.txnLog.groupCommit

Boolean

false

This property is applicable only if imq.persist.file.newTxnLog.enabled is true.

Can improve performance if imq.persist.file.sync.enabled is true and the number of concurrent transactions being processed is high:

  • If true, write operations to the transaction log are not handled by individual connection threads; instead, writes from connection threads are added to a transaction queue. The connection threads then wait until they are notified that the transactions have been logged. A separate thread periodically drains the transaction queue and writes it to the transaction log. When possible, this thread groups together multiple active transactions and writes them to the transaction log in a single operation. After the write completes, waiting client threads are notified.

  • If false, write operations to the transaction log are handled by individual connection threads. Only one thread at a time is able to write to the log.

imq.persist.file.txnLog.logNonTransactedMsgSend

Boolean

false

This property is applicable only if imq.persist.file.newTxnLog.enabled is true.

Overrides the behavior for persisting non-transacted messages (as defined by the imq.persist.file.sync.enabled property):

  • If true, non-transacted messages are written to the transaction log before they are written to the persistent store.

  • If false, non-transacted messages are written directly to the persistent store.

imq.persist.file.txnLog.logNonTransactedMsgAck

Boolean

false

This property is applicable only if imq.persist.file.newTxnLog.enabled is true.

Overrides the behavior for persisting non-transacted message acknowledgements (as defined by the imq.persist.file.sync.enabled property):

  • If true, acknowledgements of non-transacted messages are written to the transaction log before they are written to the persistent store.

  • If false, acknowledgements of non-transacted messages are written directly to the persistent store.


JDBC-Based Persistence Properties

Table 17-8 lists the broker properties related to JDBC-based persistence. The first of these properties, imq.persist.jdbc.dbVendor, identifies the database vendor being used for the broker's persistent data store; all of the remaining properties are qualified by this vendor name.

Table 17-8 Broker Properties for JDBC-Based Persistence

Property Type Default Value Description

imq.persist.jdbc.dbVendor

String

None

Name of database vendor for persistent data store:

  • derby: Java DB (Oracle Corporation)

  • oracle: Oracle (Oracle Corporation)

  • mysql: MySQL (Oracle Corporation)

  • postgresql: postgreSQL

imq.persist.jdbc.connection.reaptime

Integer

300

The interval in seconds between attempts to close unnecessary database connections.

imq.persist.jdbc.max_connections

Integer

5

The maximum number of connections that should be opened to the database. The Message Queue database connection pool manager uses this value as a guide when creating new connections to the database.

imq.persist.jdbc.min_connections

Integer

5

The number of connections that are opened to the database when the Message Queue database connection pool is initialized, and the minimum number of connections that are to be kept open when unnecessary connections are closed.

imq.persist.jdbc.connection.timeoutIdle

Boolean

true

Should the Message Queue database connection pool manager considers the age of a connection in the pool?

When true, the pool manager operates as follows:

  • When closing unnecessary database connections at each imq.persist.jdbc.connection.reaptime interval, the pool manager destroys any connections in the pool that have been idle for a period longer than imq.persist.jdbc.connection.reaptime seconds, and attempts to replace them with new connections.

  • When getting a connection from the pool, the pool manager destroys the connection if it has been idle for a period longer than imq.persist.jdbc.connection.reaptime seconds and replaces it with a new connection.

imq.persist.jdbc.connection.validateOnGet

Boolean

true for brokers in enhanced clusters; otherwise, false

Should the Message Queue database connection pool manager perform extra validation when it gets a connection from the pool?

Normally, the pool manager validates a connection it gets from the pool by checking whether the connection is closed and, if possible, by checking whether a connection error has occurred on the connection.

When this property is set to true, the pool manager performs these additional validation checks:

  • For JDBC 4 connections, check whether the connection is valid.

  • Make the validation query specified by imq.persist.jdbc.connection.validationQuery on the connection.

Regardless of the value of this property, Message Queue relies on the underlying JDBC driver to return a good connection when it needs to create a new connection through the driver. Therefore, you should set imq.persist.jdbc.vendorName.driver to a vendor JDBC driver that performs connection retries when creating a new connection to the database server; for example, a ConnectionPoolDataSource.

imq.persist.jdbc.connection.validationQuery

String

per vendor

The validation query for the Message Queue database connection pool manager to use when imq.persist.jdbc.connection.validateOnGet is set to true.

imq.persist.jdbc.connection.limit

Integer

5

The maximum number of connections that can be opened to the database.

This property is deprecated and may become unsupported in a future release of Message Queue.

For security reasons, the value can instead be specified using command line options imqbrokerd dbuser and imqdbmgr u.

imq.persist.jdbc.vendorName.needpasswordFootref 1

Boolean

false

Does database from vendor vendorName require a password for broker access?

If true, the imqbrokerd and imqdbmgr commands will prompt for a password, unless you use the -passfile option to specify a password file containing it.

imq.persist.jdbc.vendorName.passwordFootref 1,Foot 2 

String

None

Password, if required, for connecting to database from vendor vendorName

imq.persist.jdbc.vendorName.property.propNameFootref 1

String

None

JMX Properties

The broker properties listed in Table 17-18 support the use of the Java Management Extensions (JMX) application programming interface by Java applications. The JMX API is used to configure and monitor broker resources.

These JMX-related properties can be set in the broker's instance configuration file (config.properties) or at broker startup with the -D option of the Broker utility (imqbrokerd). None of these properties can be set dynamically with the Command utility (imqcmd).

In addition, some of these properties (imq.jmx.rmiregistry.start, imq.jmx.rmiregistry.use, imq.jmx.rmiregistry.port) can be set with corresponding Broker utilityimqbrokerd options described in Table 16-1.

See JMX Support for further information on administrative support of JMX clients.

Table 17-18 Broker Properties for JMX Support

Property Type Default Value Description

imq.jmx.connector.activelist

Default:

/jndi/rmi://brokerHost:rmiPort
/brokerHost/brokerPort/connectorName

imq.jmx.connector.RMIconnectorName.port

Integer

None: the port is dynamically allocated

Port number of JMX connector

Used to specify a static/known JMX connector port, typically in cases where a JMX client is accessing the broker's MBean server through a firewall. See JMX Connections Through a Firewall.

imq.jmx.connector.RMIconnectorName.useSSL

Applies only when imq.jmx.connector.connectorName.useSSL is true.

If false, the JMX client runtime will validate all certificates presented to it. Validation will fail if the signer of the certificate is not in the client's trust store.

If true, validation of certificates is skipped. This can be useful, for instance, during software testing when a self-signed certificate is used.

imq.jmx.rmiregistry.start

Boolean

false

Start RMI registry at broker startup?

If true, the broker will start an RMI registry at the port specified by imq.jmx.rmiregistry.port and use the regsitry to store the JMX connector stub. (The value of imq.jmx.rmiregistry.use is ignored in this case.)

For convenience, this property can also be set at broker startup with the -startRmiRegistry option ofimqbrokerd.

imq.jmx.rmiregistry.use

Boolean

false

Use an existing RMI registry?

Applies only if imq.jmx.rmiregistry.start is false.

If true, the broker will use an existing RMI registry on the local host at the port specified by imq.jmx.rmiregistry.port to store the JMX connector stub. The existing RMI registry must already be running at broker startup.

For convenience, this property can also be set at broker startup with the -useRmiRegistry option ofimqbrokerd.

imq.jmx.rmiregistry.port

Integer

1099

Port number of RMI registry

Applies only if imq.jmx.rmiregistry.start is true or imq.jmx.rmiregistry.use is true.

This port number will be included in the URL path of the JMX service URL.

For convenience, this property can also be set at broker startup with the -rmiRegistryPort option of imqbrokerd.
