Valore restituito

Tipo: System.Data. . :: . .DataSet
A DataSet object that contains the following columns.

Column	Data type	Description
status	Int32	Maximum status of all replication agents associated with the publication, which can be one of the following values: 1 = Started 2 = Succeeded 3 = In progress 4 = Idle 5 = Retrying 6 = Failed
warning	Int32	Maximum threshold warning generated by a subscription belonging to the publication, which can be the logical OR result of one or more of the following values. 1 = Expiration. A subscription to a transactional publication has exceeded the retention period by more than the allowable threshold, as a percentage of the retention period. 2 = Latency. The time taken to replicate data from a transactional Publisher to the Subscriber exceeds the threshold, in seconds. 4 = Mergeexpiration. A subscription to a merge publication has exceeded the retention period by more than the allowable threshold, as a percentage of the retention period. 8 = Mergefastrunduration. The time taken to complete synchronization of a merge subscription exceeds the threshold over a fast network connection, in seconds. 16 = Mergeslowrunduration The time taken to complete synchronization of a merge subscription exceeds the threshold over a slow or dial-up network connection, in seconds. 32 = Mergefastrunspeed. The delivery rate for rows during synchronization of a merge subscription has failed to maintain the threshold rate over a fast network connection, in rows per second. 64 = Mergeslowrunspeed. The delivery rate for rows during synchronization of a merge subscription has failed to maintain the threshold rate over a slow or dial-up network connection, in rows per second.
subscriber	String	Is the name of the Subscriber.
subscriber_db	String	Is the name of the database used for the subscription.
publisher_db	String	Is the name of the Publisher.
publication	String	Is the name of a publication.
publication_type	Int32	Is the type of publication, which can be one of the following values: 0 = Transactional publication 1 = Snapshot publication 2 = Merge publication
subtype	Int32	Is the subscription type, which can be one of the following values: 0 = Push 1 = Pull 2 = Anonymous
latency	Int32	The highest latency, in seconds, for data changes propagated by the Log Reader or Distribution Agents for a transactional publication.
latencythreshold	Int32	Is the maximum latency for the transactional publication above which a warning is raised.
agentnotrunning	Int32	Is the length of time, in hours, during which the agent has not run.
agentnotrunningthreshold	Int32	Is the length of time, in hours, that the agent has not run before a warning is raised.
timetoexpiration	Int32	Is the length of time, in hours, before the subscription expires if not synchronized.
expirationthreshold	Int32	Is the time, in hours, before the subscription expires that a warning is raised.
last_distsync	DateTime	Is the date/time that the Distribution Agent last ran.
distribution_agentname	String	Is the name of the Distribution Agent job for the subscription to a transactional publication.
mergeagentname	String	Is the name of the Merge Agent job for the subscription to a merge publication.
mergesubscriptionfriendlyname	String	Is the friendly name of the Merge Agent job for the subscription to a merge publication.
mergeagentlocation	String	Is the name of the server on which the Merge Agent runs.
mergeconnectiontype	Int32	Connection used when synchronizing a subscription to a merge publication, which can be one of the following values: 1 = Local area network (LAN) 2 = Dial-up network connection
mergePerformance	Int32	Performance of the last synchronization compared to all synchronizations for the subscription, which is based on the delivery rate of the last synchronization divided by the average of all previous delivery rates.
mergerunspeed	Single	Is the delivery rate of the last synchronization for the subscription.
mergerunduration	Int32	Is the length of time to complete the last synchronization of the subscription.
monitorranking	Int32	Is the ranking value used to order the subscriptions in the result set, and can be one of the following values: For a transactional publication: 60 = Error 56 = Warning: performance critical 52 = Warning: expiring soon or expired 50 = Warning: subscription uninitialized 40 = Retrying failed command 30 = Not running (success) 20 = Running (starting, running, or idle) For a merge publication: 60 = Error 56 = Warning: performance critical 54 = Warning: long-running merge 52 = Warning: expiring soon or expired 50 = Warning: subscription uninitialized 40 = Retrying failed command 30 = Running (starting, running, or idle) 20 = Not running (success)
distributionagentjobid	Byte[16]	ID of the Distribution Agent job for subscriptions to a transactional publication.
mergeagentjobid	Byte[16]	ID of the Merge Agent job for subscriptions to a transactional publication.
distributionagentid	Int32	ID of the Distribution Agent job for the subscription.
distributionagentprofileid	Int32	ID of the agent profile used by the Distribution Agent.
mergeagentid	Int32	ID of the Merge Agent job for the subscription.
mergeagentprofileid	Int32	ID of the agent profile used by the Merge Agent.

Osservazioni

The EnumSubscriptions method can only be called by members of the db_owner or replmonitor fixed database roles on the distribution database.

Calling EnumSubscriptions is equivalent to executing sp_replmonitorhelpsubscription (Transact-SQL).

This namespace, class, or member is supported only in version 2.0 of the .NET Framework.
