We have Replication setup for SQL Server 2005 to Oracle server. Each table setup with separate publisher. We are having latency issue with only one table.
Snapshot get delivered successfully if we reinitialize it but after that it shows performance critical and Distributor to Subscriber history shows 'Delivering replicated transactions'. Undistributed commands are keep increasing. It marks subscriber in active after a week or so.
Process for this particular replication show suspended with wait type 'async_network_io wait'.
How do I troubleshoot the issue?
