Hi there,
our test-mirroring-system is allready and successfull running and now i have to test different scenarios for initiating a failover, before running in productive area. Is there something i have to consider for testing it? Can u give me some tips for that? I found this http://dcx.sybase.com/1101/en/dbadmin_en11/da-highavailability-s-4980336.html but i don't think this is the only possibility to test the mirror...
Another question: I found this in the documentation of HA (http://dcx.sap.com/index.html#1200/en/dbadmin/database-mirroring-overview.html): "... Any clients that were connected to the original primary server are disconnected, and any uncommitted transactions are lost. Clients must then reconnect to the database on the new primary server to continue accessing the database. When the original primary server becomes available again, it assumes the role of mirror server. "
What does it mean? Can the application use the same databasename at any time or must it be changed in the client application if the connection switched to the mirror server? Our target is, that the arbiter can unnoticed switch to the mirror server, so that the clients can continue working without disconnect and without login again with a different server name.
Thanks in advance and regards from germany Sabrina
