How to know from source and target database server that delphix is implemented for this database, is there any process running on Server because database will seems like to be independent read/write database so how can we get to know weather this database is running for Delphix.
On a target server, its pretty easy, there will be NFS mounts from the Delphix Engine mounted on the target server ( assuming a *nix target, windows with have iscsi devices from the engine ).
On a source server its a little bit more difficult, a few things you can look for though, 1. There will be a Delphix toolkit directory somewhere on the host 2. Assuming this is oracle, you can query the v$backup_files view to see if any backups have a tag like 'DLPX%', 3. Again, assuming oracle, you could look in v$session or dba_hist_active_sess_history for sessions coming from the Delphix Engine. 4. You could look for network traffic/connections to the Delphix Engine.
In both cases though, the best way would just be to login to the Delphix Engine and look at the configuration.
