Reviewing the Distributor Agents

The Distributor Agents pane displays the following replication agent types, indicating for each type the number of agents and the highest severity level:

•
Merge — in merge replications, the Merge job first applies the initial snapshot to the subscribing server (Subscriber). Then it connects to the publishing and subscribing servers to update both sides with each incremental data change that takes place.
•
Distribution — in both transactional and snapshot replications, the Distribution job applies the initial snapshot to the subscribing server. In transactional replications, this job also transfers (downloads) newly added transactions stored in the distribution database to the subscribing server.
•
Queue Reader — in transactional replication with the queued updating option, this agent moves (uploads) changes made at the subscribing server back to the publishing server, by reading messages stored in a Microsoft SQL Server queue or a Microsoft Message Queue. Then it applies those messages to the publishing server.
* 
IMPORTANT: Unlike the Distribution agent and Merge Agent, the Queue Reader agent is an optional component. Only one Queue Reader Agent job exists to service all publishing servers and publications for a given distribution database.
•
Snapshot — in all replication types, the Snapshot agent, which runs on the distributing instance, prepares and maintains the snapshot and synchronization operation. This agent prepares the snapshot files, which contain the schema and data of the entities that are to be published (both tables and database objects). The agent stores the files in the snapshot folder, and tracks synchronization status by recording the synchronization jobs in the distribution database.
•
Log Reader — in transactional replications, the Log Reader agent monitors the transaction log of each published database. It copies the transactions marked for replication from the log to the distribution database.
•
Misc. Jobs — various replication maintenance jobs, which are automatically created by Microsoft.
* 
NOTE: Some of the miscellaneous jobs are not started by default. In which case a Warning icon appears near the job’s name, and its status is Not Started. It may be advisable to start such a job manually at some point; for example, to clean up the distribution tables.

Selecting a specific agent type’s row (for example, Merge) and clicking it opens the Replication Agents drilldown, displaying only the selected agent type. For details, see Monitoring the Replication Agents .

Reviewing the Subscription Process

The Subscription pane provides data regarding the following components of the subscription process:

•
Subscribing servers — displays the total number of subscribing servers (Subscribers) that are currently making data available to other locations through replication, by hosting one or more Subscription databases. This number includes both subscribing servers that reside on the same computer as the distributing instance and subscribing servers that reside on remote computers.
Clicking this row displays a pop-up, which contains the Subscribing servers and Subscription databases tables. Each of these tables shows the displayed entity’s name, status and highest severity level.
* 
NOTE: If more than one subscribing servers exist, clicking each subscribing server on the table displays only the subscription databases residing under the selected server.
•
Subscription databases — displays the total number of subscription databases that reside under all currently subscribing servers.
Clicking this row displays a pop-up that contains a table of all subscription databases. This table is identical to the one shown when clicking the Subscribing server row, except for the filtering by server, which is carried out by clicking the Server column.
* 
IMPORTANT: Clicking each subscription database’s row opens the Replication Subscriptions drilldown, which only displays subscriptions stored on the selected subscription database. To view the entire list of subscriptions from all subscription databases, click the Subscriptions toolbar button.
•
Subscriptions — displays the total number of subscriptions that are currently receiving selected publications through the selected instance, along with an icon that indicates the highest severity level.
Clicking this row opens the Replication Subscriptions drilldown, which allows reviewing subscriptions by their type. For details, see Monitoring the Replication Subscriptions .

Reviewing Data Flow Indicators

The data flow indicators provide a representation of the average delivery rate of each of the replication agent types, except for Misc. Jobs. A numerical value indicates the average number of commands transferred using the specified agent during the specified time range.

Clicking each flow displays a pop-up that contains a description of the flow, and a chart that shows the relevant data plotted over the specified time range.

Monitoring the Replication Publications

The Replication Publications drilldown allows viewing more detailed information about all publications distributed using the selected instance.

To investigate the requested publication:
1
Select which publication type to display, by selecting the tile that represents the requested type: Snapshot, Transactional, Transactional with update, Merge or All.
* 
IMPORTANT: In each of these tiles, it is possible to filter the display to show only publications with a specific severity status, by clicking the icon that represents that status. For example, Not Started.
2
Review the requested publication data on the Publications table:
•
Severity — the highest severity level
•
Status
•
Publishing server name
•
Publication database name
•
Publication type
•
Number of subscriptions
•
Agents taking part in the transaction — Log Reader, Queue Reader, and Snapshot agents
3
Click the publication’s row to access the Publication Details screen.
The Publication Details Screen

The Publication Details screen allows tracking the process of publishing the selected publication, by displaying all components involved in the process and providing links for further investigation.

Figure 8. The Publication Details screen.

 

Similar to the Replication home page, this screen contains the following panes, each representing a stage at the replication process:

•
Publication Data — provides the publication-related data that appears on the Replication home page, that is, publishing server, publication database, and publication name, and the following data:
•
Type — the publication type (transactional, snapshot, and so on).
•
Status — can have one of the following values: Running, Failed, Retrying, Idle, and Not started.
•
Last synchronized — the time and date when the publication data items residing on the subscribing and publishing server were most recently synchronized. This parameter is highly significant for publications configured to run continuously.
•
Due to expire — displays the time and date when the subscription expires, if changes recorded in the distribution database are not yet synchronized with the subscribing server.
* 
NOTE: The value displayed on the Due to expire field is set by adding the number of hours defined in the Retention value to the value displayed in the Last synchronized field. For example, if the most recent synchronization took place on 17:00, and the retention period is 14 hours, the value displayed here is 7:00.
•
Retention — indicates the predefined distribution retention period. If by the end of this period there are changes in the distribution database that have not been delivered to the subscribing server and synchronized, the subscription expires and drops.
•
Agents used by Publisher — displays the replication agent used for replicating the publication data to the subscribing server.
The agent types displayed on this pane for each publication type are as follows:
•
In snapshot, Transactional and Merge publications — Snapshot and Log Reader.
•
In Transactional with update publications — Snapshot, Log Reader and Queue Reader.
* 
IMPORTANT: To view a detailed representation of the agent’s actions using the Replication Agents drilldown, click the requested agent’s row. The Replication Agents drilldown appears, with the clicked agent’s row selected in the All Agents table. For details, see Monitoring the Replication Agents .
•
Subscription Data — provides the following data regarding each of the publication’s subscriptions:
•
Subscription database
•
Subscription status — can have one of the following values: Running, Failed, Retrying, Idle, and Not started.
* 
IMPORTANT: To view a detailed representation of a specific subscription using the Replication Subscriptions drilldown, click the requested subscription’s name. The Subscription Details screen opens, which provides detailed data about the selected subscription. For details, see The Subscription Details Screen .
