DG4MSQL 19c Windows gateway connecting to a SQL Server Always On multi-subnet listener

in Oracle Database Appliance (ODA) (MOSC) 1 commentAnswered

We are moving our sqlserver databases to AlwaysOn cluster.
When pointing to the listener oracle will be presented with 2 ips (primary and secondary)
Currently the gateway works well with our current setup Oracle dblink →through Gateway —>sql server

So my question ( I also have an SR opened)

When DG4MSQL resolves a multi-subnet AG listener that returns multiple IP addresses, does it:

  • Try all returned IPs?
  • Try them sequentially?
  • Cache a single IP?
  • Respect DNS TTL changes?
  • Support behavior equivalent to MultiSubnetFailover?

    Thank you

Howdy, Stranger!
