New tnsname entries will be needed to access the databases after their August 2016 migration to exadata.
Both databases are test environments shared by users for a variety of applications. The databases are part of the shared hosting environment with customers around the Madison campus, both within and without DoIT.
This weekend, wht1 and uwt1 are migrating to the Exadata environment. After the migrations are complete, new tnsname entries will be needed to access the databases.
The edit should be done with administrator level access. For more information, see EPM - Editing 'tnsnames.ora' and 'sqlnet.ora' Files
Contact the DoIT Help Desk if you need the updated entries.
