I have just moved from a Windows OS to HPopenvms OS. I can create an instance and database in windows but DO NOT know what to do on openVms. I do not want to use DBCA but want to write my own scripts to create the database. I can at least create the database but how do we create an instance? what is the equivalent for ORADIM? Can someone please help me?

Oracle -
OpenVms - 7.3

Thanks a lot!
