Publication Information, Warnings and Agents (Merge Publication, SQL Server 2005 and Later)

Updated: 14 April 2006

The Warnings and Agents tab is available for Distributors running SQL Server 2005 and later versions; the Agents tab is available for previous versions. The Warnings and Agents tab allows you to perform the following tasks for the selected publication:

  • Enable warnings.
  • Specify thresholds associated with warnings.
  • Define alerts associated with warnings.
  • View summary information on the Snapshot Agent for the publication.
  • Access more detailed information about the Snapshot Agent.

By default, Replication Monitor displays warnings for uninitialized subscriptions: a status of Uninitialized subscription is displayed as a warning in the Status column of pages that include subscription information. For merge publications, you can specify whether these additional conditions result in warnings:

  • Imminent subscription expiration.
    This corresponds to the option Warn if a subscription will expire within the threshold. If the specified threshold is met or exceeded, the subscription status is displayed as Expiring soon/Expired (unless an issue with a higher priority needs to be displayed).
  • Exceeding the specified synchronization time.
    This corresponds to the options Warn if a merge length for dialup connections exceeds the threshold and Warn if a merge length for LAN connections exceeds the threshold. Both of these thresholds can be set, but only one is used during a given synchronization. The Merge Agent applies the appropriate threshold based on the connection type.
    If the specified threshold is met or exceeded, the subscription status is displayed as Long-running merge (unless an issue with a higher priority needs to be displayed).
  • Falling short of processing the specified number of rows in a given amount of time.
    This corresponds to the options Warn if rows merged per second for dialup connections is less than the threshold and Warn if a merge length for LAN connections exceeds the threshold. Both of these thresholds can be set, but only one is used during a given synchronization. The Merge Agent applies the appropriate threshold based on the connection type.
    If the specified threshold is met or exceeded, the subscription status is displayed as Performance critical (unless an issue with a higher priority needs to be displayed).

When you enable a warning, you also set a threshold. For example, if you enable the warning Warn if a merge length for LAN connections exceeds the threshold, set the maximum allowable length of time for a merge synchronization.

In addition to displaying a warning in Replication Monitor, reaching a threshold can also trigger an alert. Alerts are defined by clicking Configure Alerts and providing information in the Configure Replication Alerts dialog box.

For more detailed information and tasks related to the Snapshot Agent, right-click the row for the agent, and then click an option on the shortcut menu.

Enabled

Select to enable a warning and specify a threshold.

Warning

A description of the warning associated with a threshold.

Threshold

Specify a value for the threshold.

Configure Alerts

Select a row in the Warnings grid, and click Configure Alerts to launch the Configure Replication Alerts dialog box. The dialog box allows you to define an alert, which is associated with the selected threshold and warning.

Discard Changes

Click to discard any changes to warnings and thresholds.

Clicking Discard Changes does not affect alerts defined in the Configure Replication Alerts dialog box.

Save Changes

Click to save any changes to warnings and thresholds.

Status

The status of the Snapshot Agent. The following list shows the possible status values:

  • Error
  • Retrying failed commands
  • Not running
  • Running
Agent

The Snapshot Agent. This is the only agent associated with a merge publication. The Merge Agent is associated with subscriptions to this publication. For more information, see How to: View Information and Perform Tasks for the Agents Associated With a Subscription (Replication Monitor).

Last Start Time

The last time the agent started.

Duration

The amount of time the agent has run. The time represents elapsed time if the agent is currently running and total time if the agent has run previously.
