This diagram show the Dbvisit Replicate solution for providing zero-down-time migrating for migrating databases or platforms from one version to another with little or no downtime.
Partially supported OS solution
This diagram shows the Dbvisit Replicate solution for replicating data from an older Operating System that may not supported running the Dbvisit Replicate software. This solution uses NFS to mount the redo and archive logs onto a dedicated Mine server.
Notes:
- The NFS shares on the Mine server has to "look" the same as on the Source Site. So the redo and archive locations have to be in the same location on the Mine Server as on the Source Site. This is because the Mine process on the Mine Server connects to the source database to obtain the redo and archive log locations from Oracle and will expect to find the redo and archive logs in the same location on the Mine server. Note that on Linux and Unix this can be achieved with soft links.
- The setup wizard is run from the Mine Server. Ensure the Mine server has a tnsnames.ora with a connection string to both the source and target databases.
Offloading reporting solution
This diagram shows Dbvisit Reporting to offload running reports onto a dedicated database. This reporting database is being kept up to date in real-time.
