SYMPTOMS

Consider the following scenario. You synchronize a Microsoft SQL Server 2005 Compact Edition (SQL Server Compact Edition) subscription to a Microsoft SQL Server 2005 publication. During the synchronization, you disconnect the subscriber. In this scenario, you receive the following error message when you try to synchronize the SQL Server Compact Edition subscription again:
System.Data.SqlServerCe.SqlCeError: A call to SQL Server Reconciler failed. Try to resynchronize.

The merge process failed because it detected a mismatch between the replication metadata of the two replicas, such that some changes could be lost leading to non-convergence. This could be due to the subscriber not having synchronized within the retention period, or because of one of the replicas being restored to a backup older than retention period, or because of the publisher performing more aggressive cleanup on articles of type download-only and articles with partition_options = 3. (Source: MSSQL_REPL, Error number: MSSQL_REPL-2147199363)

The common generation watermark is invalid at this replica since it does not exist or metadata for changes not yet propagated may have been cleaned up. (Source: MSSQLServer, Error number: 21800)
This problem occurs if the following conditions are true:
  • You disconnect from the database when SQL Server Compact Edition is processing the .out file from the virtual directory.

    Note The virtual directory is on the server that is running Internet Information Services (IIS).
  • The partition options property of the published article is set to the 3 value.
  • The SQL Server 2005 publication uses the dynamic filtering feature.
  • The ExchangeType property of the Replication Merge Agent is set to the Bidirectional value or to the Download value.

CAUSE

This problem occurs because the merge replication metadata at the publisher differs from the merge replication metadata at the subscriber. When you try to synchronize the SQL Server Compact Edition subscription again, the merge replication process detects the difference. Therefore, you receive the error message.
