Publication Information, All Subscriptions (Merge Publication)

Updated: 14 April 2006

The All Subscriptions tab displays information on all subscriptions to the selected merge publication.

For more detailed information and tasks related to a subscription, right-click the row for that subscription, and then click an option on the shortcut menu.

Show

Microsoft SQL Server 2005 and later versions only. Select the subscription states to display for the selected subscription type. For example, you can select to display only those subscriptions that have an error.

Status

The status of each subscription, which is determined by the status of the Merge Agent.

By default, the grid containing subscription information is sorted by the Status column (and then sorted by the Performance column for those subscriptions with the same status). The following list shows the possible status values and the sort order for the values (for example, errors are always shown at the top of the grid).

  • Error
  • Performance critical (SQL Server 2005 and later versions only)
  • Long-running merge (SQL Server 2005 and later versions only)
  • Expiring soon/Expired (SQL Server 2005 and later versions only)
  • Uninitialized subscription (SQL Server 2005 and later versions only)
  • Retrying failed command
  • Synchronizing
  • Not synchronizing

The sort order also determines which value is displayed if a given subscription is in more than one state. For example, if a subscription has an error and is expiring soon, the Status column displays Error.

The status values Performance critical, Long-running merge, Expiring soon/Expired, and Uninitialized subscription are warnings. When a warning is displayed, the Status column also displays if an agent is synchronizing. For example, the status could be Synchronizing, Performance critical.

The status values Expiring soon/Expired and Long-running merge can be displayed only if thresholds are set. The status value Performance critical can be displayed only after five synchronizations of subscriptions with the same connection type (dial-up or LAN). For information about performance measurements and setting thresholds, see Monitoring Performance with Replication Monitor and Setting Thresholds and Warnings in Replication Monitor.

Subscription

The name of each subscription, in the form:SubscriberName: SubscriptionDatabaseName.

Friendly Name

SQL Server 2005 and later versions only. The description of each subscription. The description is entered in the Subscription Properties dialog box or specified with the @description parameter of sp_addmergesubscription (Transact-SQL) or sp_addmergepullsubscription (Transact-SQL). Users often use the description as a "friendly name" or nickname for the subscription.

Performance

SQL Server 2005 and later versions only. The performance rating for each subscription, based on the most recent measurements of delivery rate taken by Replication Monitor. The rating is determined by comparing individual subscription performance to the average historical performance of subscriptions to the publication that have the same connection type (dial-up or LAN). Replication Monitor displays a value after five synchronizations have occurred with 50 or more changes each over the same type of connection. If there have been less than five synchronizations with 50 or more changes or the most recent synchronization has less than 50 changes, this column is blank.

ms177162.note(en-US,SQL.90).gifNote:
Performance is based on the connection type displayed in the Connection column; therefore it is possible for a subscription with a lower delivery rate to display a better performance rating than another subscription if the first subscription is synchronized over a slower connection.

The performance rating is one of the following values:

  • Excellent
  • Good
  • Fair
  • Poor

For more information on how performance ratings are defined and how performance thresholds are set, see Monitoring Performance with Replication Monitor.

Delivery Rate

The number of rows per second processed by the Merge Agent.

Last Synchronization

The time at which the Merge Agent last ran. Changes may or may not have been processed during this synchronization. If synchronization is in progress, a percentage complete value is displayed.

Duration

The amount of time the Merge Agent has run during the last synchronization. The time represents elapsed time if the Merge Agent is currently synchronizing and total time if the Merge Agent has synchronized previously.

Connection

SQL Server 2005 and later versions only. The type of connection between the Subscriber and the Publisher. The possible values are LAN, Dialup, and Internet. The Internet value is displayed if the subscription uses Web synchronization.
