Valeur de retour

Type : 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.

mergePerformance

Int32

Notes

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.
