You administer several Microsoft SQL Server 2012 database servers. Merge replication has
been configured for an application that is distributed across offices throughout a wide area
network (WAN).
Many of the tables involved in replication use the XML and varchar (max) data types.
Occasionally, merge replication fails due to timeout errors.
You need to reduce the occurrence of these timeout errors.
What should you do?
A.
Set the Merge agent on the problem subscribers to use the slow link agent profile.
B.
Create a snapshot publication, and reconfigure the problem subscribers to use the
snapshot publication.
C.
Change the Merge agent on the problem subscribers to run continuously.
D.
Set the Remote Connection Timeout on the Publisher to 0.
Explanation:
When replication is configured, a set of agent profiles is installed on the Distributor. An agent
profile contains a set of parameters that are used each time an agent runs: each agent logs
in to the Distributor during its startup process and queries for the parameters in its profile.
For merge subscriptions that use Web synchronization, profiles are downloaded and stored
at the Subscriber. If the profile is changed, the profile at the Subscriber is updated the next
time the Merge Agent runs. For more information about Web synchronization, see Web
Synchronization for Merge Replication.
Replication provides a default profile for each agent and additional predefined profiles for the
Log Reader Agent, Distribution Agent, and Merge Agent. In addition to the profiles provided,
you can create profiles suited to your application requirements. An agent profile allows you
to change key parameters easily for all agents associated with that profile. For example, if
you have 20 Snapshot Agents and need to change the query timeout value (the QueryTimeout parameter), you can update the profile used by the Snapshot Agents and all
agents of that type will begin using the new value automatically the next time they run.
You might also have different profiles for different instances of an agent. For example, a
Merge Agent that connects to the Publisher and Distributor over a dialup connection could
use a set of parameters that are better suited to the slower communications link by using the
slow link profile.
