New objects and new attributes for objects in WebSphere MQ 7.1 and 7.5

Technote (FAQ)


Question

You want to know if there are new objects and new attributes for objects in WebSphere MQ 7.1 and 7.5

Answer


++ New objects in MQ 7.1 (included in MQ 7.5)

These are shown as new folders in the MQ Explorer 7.1 and 7.5

CHLAUTH => New in 7.1
WebSphere MQ > Reference > Administration reference > MQSC reference > The MQSC commands
SET CHLAUTH
Use the MQSC command SET CHLAUTH to create or modify a channel authentication record.

COMMINFO => New in 7.1
WebSphere MQ > Reference > Administration reference > MQSC reference > The MQSC commands
DEFINE COMMINFO
Use the MQSC command DEFINE COMMINFO to define a new communication information object. These objects contain the definitions required for Multicast messaging.


++ The rest of this technote provides the details on the rest of the new attributes on existing objects

Object: Local Queue (QLOCAL)
New attribute: CUSTOM => New in 7.1
WebSphere MQ > Reference > Administration reference > MQSC reference > The MQSC commands
ALTER queues
CUSTOM(string)
The custom attribute for new features.
This attribute is reserved for the configuration of new features before separate attributes are introduced.

Object: Transmission Queues:
New attribute: CLCHNAME => New in 7.5
WebSphere MQ > Reference > Administration reference > MQSC reference > The MQSC commands
ALTER queues
CLCHNAME(channel name)
CLCHNAME is the generic name of the cluster-sender channels that use this queue as a transmission queue. The attribute specifies which cluster-sender channels send messages to a cluster-receiver channel from this cluster transmission queue.

Object: Topic
New attributes:
COMMINFO => New in 7.1

CUSTOM => New in 7.1

MCAST => New in 7.1
WebSphere MQ > Reference > Administration reference > MQSC reference > The MQSC commands
DEFINE TOPIC
MCAST: Specifies whether multicast is allowable in the topic tree.

USEDLQ => New in 7.1
WebSphere MQ > Reference > Administration reference > MQSC reference > The MQSC commands
DEFINE TOPIC
USDELQ: Determines whether the dead-letter queue is used when publication messages cannot be delivered to their correct subscriber queue.


+ Channels

WebSphere MQ > Reference > Administration reference > MQSC reference > The MQSC commands
DEFINE CHANNEL

Object: Server-Connection Channel (SVRCONN)
New attribute: DISCINT => New in 7.1 for Distributed (Unix, Windows)
The minimum time in seconds for which the channel waits for a message to arrive on the transmission queue, after a batch ends, before terminating the channel. A value of zero causes the message channel agent to wait indefinitely.
The value must be in the range zero through 999 999.
In MQ 7.0: This parameter is valid only for SVRCONN on z/OS and for SDR, SVR, CLUSSDR, CLUSRCVR.
In MQ 7.1 it is available now in Unix and Windows for SVRCONN, and continues to be available for SDR, SVR, CLUSSDR, CLUSRCVR.

Object: Client-Connection Channel (CLNTCONN)
New attribute: DEFRECON => New in 7.1
Specifies whether a client connection automatically reconnects a client application if its connection breaks.

Object: Cluster Receiver Channel (CLUSRCVR)
New attributes:
BATCHLIM => New in 7.1
The limit, in kilobytes, of the amount of data that can be sent through a channel before taking a sync point.

RESETSEQ => New in 7.1
Pending reset sequence number.
This is the sequence number from an outstanding request and it indicates a user RESET CHANNEL command request is outstanding.

USEDLQ => New in 7.1
Determines whether the dead-letter queue is used when messages cannot be delivered by channels.


Object: Cluster Sender Channel (CLUSSDR)
New attributes:
BATCHLIM => New in 7.1
RESETSEQ => New in 7.1
USEDLQ => New in 7.1

Object: Receiver Channel (RCVR)
New attributes:
RESETSEQ => New in 7.1
USEDLQ => New in 7.1

Object: Requester Channel (RQSTR)
New attributes:
RESETSEQ => New in 7.1
USEDLQ => New in 7.1

Object: Sender Channel (SDR)
New attributes:
BATCHLIM => New in 7.1
USEDLQ => New in 7.1

Object: Server Channel (SVR)
New attributes:
BATCHLIM => New in 7.1
RESETSEQ => New in 7.1
USEDLQ => New in 7.1
