Topic status attributes for subscribers
For a given topic, the set of attributes that hold subscriber status information.
For each attribute, there is a brief description of what information the attribute shows. The table also gives the equivalent MQSC parameter for the DISPLAY TPSTATUS command. For more information about MQSC commands, see Administration using MQSC commands in IBM® Knowledge Center.
Attribute | Meaning | MQSC parameter |
---|---|---|
Topic String | The Topic String identifies the topic node. It matches information from a publisher to a subscriber interested in that information. | TOPICSTR |
Subscription ID | Identifier is assigned by the queue manager as a unique identifier for the subscription. | SUBID |
User | The user identifier that is associated with the subscription. | SUBUSER |
Durable | Indicates whether durable subscriptions are allowed or not. | DURSUB |
Type | The Type of subscription
indicates how the subscription was created. The subscription types
are: API: Subscription created via an MQSUB API request. ADMIN: Subscription created via a DEF SUB MQSC or PCF command. ADMIN is also used to indicate that a subscription has been modified via administrative command. PROXY: Subscription created internally for routing publications through a queue manager network. |
SUBTYPE |
Connection ID | The currently active CONNID that has opened this subscription. It is used to detect local publications. | ACTCONN |
Resume date | The date of the most recent MQSUB which connected to this subscription. | RESMDATE |
Resume time | The time of the most recent MQSUB which connected to this subscription. | RESMTIME |
Message count | The number of messages put to the destination specified by this subscription since it was created, or since the queue manager was restarted, whichever is more recent. This number might not reflect the total number of messages that are, or have been, available to the consuming application. This is because it might also include publications that were partially processed but then undone by the queue manager due to a publication failure, or publications that were made within syncpoint that were rolled-back by the publishing application. | NUMMSGS |
Multicast reliability indicator (%) | Indicator of the reliability of the multicast
messages. The values are expressed as a percentage. A value of 100
indicates that all messages are being delivered without problems.
A value less than 100 indicates that some of the messages are experiencing
network issues. To determine the nature of these issues, you
can enable event message generation, using the COMMEV parameter
of the COMMINFO objects, and examine the generated event messages.
Two values are returned:
