Automating replication using sqldmo


Automating replication using sqldmo Aaron

sql server replication:
I am currently developing an application that utilizes SQL Server 2000/MSDE using replication. What I am finding is that when the client is not attached to the network (in the case of a laptop, etc.) the replication will attempt to contact the subscriber 10 times and then it no longer tries. I then have to manually restart the replication process. Is there a way to do this using sqldmo and if so, can you point me to some good examples or sample code

If you want to run the agents programatically, have a look
at the activex controls. There is some sample code on MSDN
(http://msdn.microsoft.com/library/default.asp?
url=/library/en-us/replprog/rp_replsamp_5a9f.asp).

Hi -
Also the sample codes are shipped with the SQL server CD. Do a
custom install of sample codes if not done already. The default location of
replication DMO sample code is : %program files\Microsoft SQL
server\80\Tools\DevTools\Samples\sqlrepl.

For information on how to use these sample codes are available in books
online. Search for "programming replication" in BOL.

Chandra

I have been dancing this crazy dance all week. This code works for me (c#)
however I have a problem with the CurrentRunStatus permanently returning
Idle if anybody out there knows why. Hope this helps though can't promise
it is the correct way of doing things.

Aido.

// Connect to the database.

SQLDMO.SQLServer2Class svr = new SQLDMO.SQLServer2Class();

svr.Connect("(local)", "sa", "sapassword");



// Iterate through pull subscriptions

SQLDMO.ReplicationDatabase dbase =
svr.Replication.ReplicationDatabases.Item("DatabaseName");

SQLDMO.MergePullSubscriptions pullsubs = dbase.MergePullSubscriptions;

for(int pullsubidx = 1; pullsubidx <= pullsubs.Count; pullsubidx++)

{

SQLDMO._MergePullSubscription pullsub = pullsubs.Item(pullsubidx);

// Find the job matching the subscriptions job id

SQLDMO._Job job = null;

for(int jobidx = 1; jobidx <= svr.JobServer.Jobs.Count; jobidx++)

{

job = svr.JobServer.Jobs.Item(jobidx);

if (job.JobID == sub.MergeJobID)

return job;

}

// If we have a job check whether it needs to be run

if (job != null)

{

int date = job.LastRunDate;

int time = job.LastRunTime;

bool isdue = false;

// date is 0 if job never run

if (date == 0)

isdue = true;

// Otherwise compute the expiry date

else

{

System.DateTime due = new System.DateTime(

date / 10000, (date % 10000) / 100, (date % 100),

time / 10000, (time % 10000) / 100, (time % 100))

+ new TimeSpan(Module.DatabaseSyncRate, 0, 0);

isdue = DateTime.Now > due;

}

// Check status and reschedule if not

// active and due.

job.Refresh(); // Not sure whether this updates CurrentRunStatus

if (job.CurrentRunStatus ==
SQLDMO.SQLDMO_JOBEXECUTION_STATUS.SQLDMOJobExecution_Idle && isdue)

{

System.Diagnostics.Trace.WriteLine(String.Format("Synchronizing
database '{0}'", job.Name), "Replicator Trace");

job.Start(Type.Missing);

}

Appologies

the line

if (job.JobID == sub.MergeJobID)

return job;

should read

if (job.JobID == sub.MergeJobID)

break;

(it was chopped out of a sub routine).

Aido.
