Using EXPDP to export a FULL Oracle database backup is an easy task. It gets a little complex when you have specific requirements with what to extract, for example: export a single table or schema, or some particular query output, or INCLUDE some list of object and vice versa i.e. EXCLUDING some objects from the backup. Well I intend to provide a full picture on various options with examples but it will increase the post length to uncontrolled manner so I'll break down each type of activity and then create a MASTER article explaining all features for your help.
For this post, I'll show your 2 things,
- Exporting a FULL Database backup.
- Breaking the DUMP file into multiple pieces.
Note: I am running this on my personal laptop for practice sessions. Due to limitation of resources, I might do something that you shouldn't do in REAL WORLD. So be careful and improvise as per your scenario. If you are also learning, feel free to play with database, that's how you learn :)
Let's begin.
1) Login to the database you want to export.
[oracle@oravm19c admin]$ sqlplus / as sysdba

2) Create directory you want to use in export. This directory will hold the DUMP files'. Also, I'll be using SYS for the EXPDP so I don't need to grant anything to this schema. If you are using some other user to EXPORT. You'll need to grant that user needed privilege.
SQL> create directory DB_DUMP as '/u01/app/expdp';
Directory created.
SQL> grant read, write on directory DB_DUMP to XYZ; SQL> grant DATAPUMP_EXP_FULL_DATABASE to XYZ;
