Issue With Web Synchronization & Merge Replication Microsoft SQL Server / 2008 r2

Question

I am extending our network by placing a xenserver box at a remote location to reduce outages for our web resources. All our servers are on xenserver, with MS Server 2008r2 and SQL Server 10. I must add I am a developer, not a sysadmin, so I have never done a db replication setup before.

I have successfully got one server working as publisher / distributor(SVR-DBDISTRIB) and another working as subscriber (SVR-DBREPLICA). They are happy to update each other with no faults. As one server has to go off site, I am planning to use web synchronization from one of our ms web servers (Server 2008r2 / IIS 7.5). I have added all the repl_merge, etc passwords, self-certified certificate, installed the SQL connectivity, etc features to the IIS box and I have got replisapi.dll working with certificates saved to trusted certificate root on the subscriber (so no certificate warnings come up when I call https://server.domain/SQLReplication/replisapi.dll). I have run the replisapi.dll?diag when logged in using the web servers admin password and everything is working. I can also log in with the IISSQLRepl password I have set up to hit the web server on basic authentication from the subscriber (again with no certificate issue). There are no proxies set up on the system.

When I create a new web synchronization publication on SVR-DBDISTRIB that works with non-web replication, the subscriber on SVR-DBREPLICA can communicate with the publisher as the subscription shows up in SVR-DBDISRIB. The agents at the distributor have no error messages but no table updates appear at the subscriber, although I do get the following (rather unhelpful) error message:

The system cannot find the file specified

I understand that there is a 'verbose' setting and I am not sure if this is the verbose output. All the MS technet documentation talks about using SQL Enterprise Manager (discontinued from server 2000) to do this.

Any help or advice on where to look would be appreciated - this is the last job I need to finish before pushing it out the door and I have spend 2 days on this now...

Answer 1

if your networks are connected use network share instead of ftp or web sync. Much easier to maintain and you don;t need extra web server ;)
