One of the questions we get asked a lot is:
In terms of ORACLE licensing, do we need a separate Orcacle license for the DR / Standby database?
Yes, you require a separate Oracle license for the DR / Standby database. This license has to be the same license metric as the primary database. This means that if you license the primary database per CPU, then the standby database must also be licensed per CPU (although it does not have to be the same number of CPU).
Or if the primary database is licensed per user then the standby database must also be licensed per user.
It must be the same license type, so if your primary database is Standard Edition, then the standby database must also be Standard Edition.
We might go for Standard Edition Processor based licensing option, which allows us to have up to 4 CPU in total. If we have a production / primary server with 4 CPU, will the licensing work with standby database?
You will require a separate Oracle Standard Edition license for the standby database which is also processor based. With Dbvisit we include the standby database with the Dbvisit license for the primary database.
How would the licensing work for Multiple standby databases?
Oracle is licensed per server not per database, so you can have as many databases as you wish on the same server. With Dbvisit we have 2 types of licenses, Single Instance or Multiple Instance (or server license). If you have Dbvisit for 1 primary database, then the Single Instance license is needed. If you have Dbvisit for more than 1 primary database on the same server, then the Multiple Instance license is required. With all Dbvisit licenses you can have unlimited standby databases.
