New objects and new attributes for objects in WebSphere MQ 7.1, 7.5 and 8.0

Technote (FAQ)


Question

You want to know if there are new objects and new attributes for objects in WebSphere MQ 7.1, 7.5 and 8.0

Answer


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

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

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.

CLROUTE => New in 8.0

WebSphere MQ 8.0.0>WebSphere MQ>Reference>Administration reference>MQSC reference>The MQSC commands>
DEFINE TOPIC
CLROUTE - The routing behavior to use for topics in the cluster defined by the CLUSTER parameter.
DIRECT - When you configure a direct routed clustered topic on a queue manager, all queue managers in the cluster become aware of all other queue managers in the cluster. When performing publish and subscribe operations, each queue manager can connect direct to any other queue manager in the cluster.
TOPICHOST - When you use topic host routing, all queue managers in the cluster become aware of the cluster queue managers that host the routed topic definition (that is, the queue managers on which you have defined the topic object). When performing publish and subscribe operations, queue managers in the cluster connect only to these topic host queue managers, and not directly to each other. The topic host queue managers are responsible for routing publications from queue managers on which publications are published to queue managers with matching subscriptions.


+ 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

Object: Channels in general
New attribute in 8.0:
CERTLABL(' ') => Only for certain types: not for CHLTYPE(CLUSSDR)

WebSphere MQ 8.0.0 > WebSphere MQ > Reference > Configuration reference > Channel attributes > Channel attributes in alphabetical order >
Certificate label (CERTLABL)
This attribute specifies the certificate label of the channel definition.
The label identifies which personal certificate in the key repository is sent to the remote peer. The certificate is defined as described in Digital certificate labels.

+ New types for AUTHINFO (New in 8.0)
SYSTEM.DEFAULT.AUTHINFO.IDPWLDAP - AUTHTYPE(IDPWLDAP)
SYSTEM.DEFAULT.AUTHINFO.IDPWOS - AUTHTYPE(IDPWOS)
DEFINE AUTHINFO

AUTHTYPE - The type of authentication information.
CRLLDAP - Certificate Revocation List checking is done using LDAP servers.
IDPWLDAP - Connection authentication user ID and password checking is done using an LDAP server.
IDPWOS - Connection authentication user ID and password checking is done using the operating system.
OCSP - Certificate revocation checking is done using OCSP.


+ Adding attribute CHCKCLNT to CHLAUTH
Example:
SET CHLAUTH('SYSTEM.ADMIN.SVRCONN') +
CHCKCLNT(ASQMGR) +

WebSphere MQ 8.0.0 > WebSphere MQ > Reference > Administration reference > MQSC reference > The MQSC commands >
SET CHLAUTH
CHCKCLNT - Specifies whether the connection that matches this rule and is being allowed in with USERSRC(CHANNEL) or USERSRC(MAP), must also specify a valid user ID and password. REQDADM
