MVS South System
New Oracle Instances—ORAD and ORAP
In December, two new Oracle (version 7.3) instances were installed and made available on the MVS South system to replace the current production instance ORAT. Users can now choose between two environments—ORAD for development and ORAP for production.
ORAD is the appropriate place for developing new queries and applications, or for making changes to existing applications. When development and testing have been successfully completed, users can then implement the new systems or changes on the production system, ORAP. A major advantage of the two instances is that users can migrate between them without making changes to code, thus saving time and eliminating potential errors.
Migrate from ORAT Now
Users have begun migrating applications and data from the ORAT instance to ORAD and ORAP. ORAT will be turned off once the migrations are completed. For assistance with migration issues, please call the Database Technology Unit at (301) 496-9158. Information on the new features and connectivity specifics can be obtained at http://silk.nih.gov/dbtech.
