Merge Replication and MSDE

I suppose it depends on what you want to do as a result
of the synchronization finishing. The easiest way to make
the process event-driven is to add an additional step to
the merge agent's job and modify the other steps to
always culminate in the execution of your new step. This
additional step could execute a SP, or run a command,
whatever you have in mind.
The alternatives are is to query the history tables (eg
MSdistribution_history), or
tempdb.dbo.MSreplication_agent_status or run the
penultimate script on
http://www.replicationanswers.com/OtherSQL.htm. These 3
solutions each are essentially polling methods and you
might end up doing a lot of unnecessary server work that
way.

You see I want to make sure the the Subscribers are online long enough to
finish the merge replication.
Is it possible to Start the merge replication using a Stored Procedure
etc... ? That way the users can initiate the merge replication themselves.
By the way, MS Access 2003 is used as a front end to the MSDE database, so
inisiating a merge replication would preferably be started from Access (and
hopefully the user would get some indication that the merge replication was
completed)

|||To kick off the merge agent using stored procedures, you
can use sp_start_job. There are other programattic
options, usually involving ActiveX controls or command-
line execution, but the above system stored procedure
should do.

|||Can you give me an example on how a sp_start_job would typically look like to
start the merge replication.
Another question: There are several subscribers. Is it one merge agent for
each subscriber ?

One merge agent per subscriber - yes.

I can then check the status of the Job to determine when it has completed.
