A DBA Must Keep Record of following information

A DBA Must Keep Record of following information

During the stress of a recovery situation, it is important that you have all necessary information at your disposal. This is especially true if for some reason you need to contact Oracle Support because you run into a problem that you do not understand. You should have the following documentation about the database & hardware configuration:

You should keep this information both in electronic and hard copy form. For example, if you save this information in a text file on the network or in an email message, then if the entire system goes down, you may not have this data available.

SELECT DBID, DATABASE_NAME FROM V$DATABASE;
63198034        SHAKIR.WORLD
SELECT * FROM GLOBAL_NAME;

SHAKIR.WORLD
