IGeoDataServer.CreateReplica How to download directly to a file geodatabase

MKa — Tue, 18 Apr 2017 21:22:25 GMT

I am creating a disconnected checkout replica using CreateReplica on my PARENT Geodataserver, then Importing into a CHILD geodatabase. My customers will be replicating from my PARENT Geodatabase to locations worldwide and I was wondering if there is a more efficient way of doing this. I have went through every option available for CreateReplica and cannot find a more efficient way then this below. It seems to take forever for the import to happen. It takes me over a minute and I am located in the same space as the server itself. I have had one user timeout at ten minutes, so I thought I would take another look.

//Create the Replica on the Server

IGDSData gsdata = ParentGeoDataServer.CreateReplica("", ReplicaName.ToUpper(), gpReplicaDesc, replicaOptions, replicaExportOptions, esriGDSTransportType.esriGDSTransportTypeEmbedded);

//Import the Replica

ChildGeoDataServer.ImportData(gsdata, esriGDSImportFormat.esriGDSImportFormatFileGDB);

Does anyone know how to perform this action in the Help for IGeoDataServer.CreateReplica Method. I have searched the ENTIRE internet trying to do this documentation here.

"For check-out replicas, you can also choose to replicate directly to a file geodatabase or personal geodatabase. Here the output is the replica geodatabase and therefore no import is required."

Then I could just skip the import if somehow I could cast the IGDSData object to my ChildGeoDataServer (File GDB) and not have to do that long import process.

Hi,

use IGeoDataServer.CreateReplica(...) if you need to do replication in a "disconnected environment", where your parent database can make NO connection to your replica database.

If you want to replicate your data DIRECTLY into a replica (file) geodatabase you need to switch to a "connected environment". In that case you have to make use of the IReplicationAgent Interface from the ESRI.ArcGIS.GeoDatabaseDistributed module:

IGeoDataServer parentGeoDataServer = ...

IWorkspace myFileGdbWorkspace = ...

IGeoDataServer childGeoDataServer = ... // init from myFileGdbWorkspace ...

IReplicationAgent replicationAgent = new ReplicationAgentClass();

IGPReplicaOptions replicaOptions = ... replicationAgent.CreateReplica(

parentGeoDataServer.DefaultWorkingVersion,

parentGeoDataServer,

childGeoDataServer, ...

Hope that helps...

Karl,

We originally did use the ReplicationAgent in the connected environment but ran into a number of issues with the connectivity and with the processes basically failing during transfer. We think the replication agent was also slower than the "disconnected download and import". I am downloading a Replica with about 14 feature classes.

Since I can't directly download to my Child File Geodatabase like I want, is there a way to do download and import each feauture class of the parent replica to my File Geodatabase individually instead of collectively. I have noticed that when I take a subset of my replica the speed is greatly improved. I feel that the Import function itself is taking so long to initiate the import. I say this because the ReplicaLog always shows the initial Feature class taking a very long time, and the subsequent Feature Classes of the Replica import rather quickly. Here is the first couple lines of my ReplicaLog

Any advice would be great. We are starting up my Addin in some worldwide locations and I feel the import speed could be a problem for us. I don't know if there is any ESRI TCP/IP Recommendations that our network guys might be able to employ for this GEODataServiceURL.
