Hi All,
I have i
nstalled SAP NW 7.4 EHP7 with MS SQL 2012 as database on Windows 2012 R2. The installation for both database and sap are locally, using the server's computer name.
Our client is planning for HA on the MSSQL. They have a new box where MSSQL 2012 is installed. They thinking of just in case of a disaster, or the database may corrupt, they have the secondary database server to switch to. They have their Microsoft consultant for this setup they called "AlwaysON" for MSSQL. I looked to the profile parameter and the db is pointing to the server's computer name (SAPDBHOST).
They have a question on me that I'm not sure on what to answer to them. This is their question so that they can go on with the project:
"Scenario = MS SQL1 ( Primary ) , MS SQL2 ( Secondary )
Does SAP uses a static connection string to connect to the Ms SQL Server ( Primary )? Can we modify it use a Listener connection string instead?
Where can we find this conection string ? And How can we modify it? This will allow the users to continously use the SAP application seamlessly with out the need to modify the DB connections string when a disaster in MS SQL1 ( Primary ) happens. Always On HA/DR will automatically fail it over and use MS SQL2 ( Secondary )."
Thanks in advance. Hope someone can help me on this.
