Licence costs comparison
DBSentinel`s license model corresponds to the simplicity of the overall solution.
For each physical source server only one DBSentinel license is required.
Contrary to our competitors when licensing DBSentinel the number of engaged sockets and CPU cores as well as the number of installed instances does not matter nor does it matter which edition of the installed Oracle databank will be used.
Mirroring the license rule only one DBSentinel license for each physical server will be required when using a RAC or any other cluster solution.
Again the number of standby databases (up to 10 for each primary are possible) does not come into play when licensing DBSentinel.
