Ii. Import and export Methods

Solution 1:
1.1 database backup-logical backup:
Expdp wzzjxt/wzzjxt @ wzzj DIRECTORY = data_dump_dir dumpfile = % backup_file %. dmp
1.2 database restoration-logical Restoration:
Impdp aaa/aaa directory = data_dump_dir dumpfile = px. DMP REMAP_SCHEMA = px: aaa
Example:
Create users and grant permissions
Create directory DATA_PUMP_DIR as 'd :\';
Create user v106 identified by v106;
Grant dba, connect, resource to v106;
Grant read, write on directory DATA_PUMP_DIR to v106;


Impdp sanyuechu/sanyuechu DIRECTORY = DATA_PUMP_DIR DUMPFILE = TEST. DMP

Solution 2:
1.1 database backup-logical backup:
Exp userName/passWord @ IP file = d:/database file. dmp

Database restoration-logical Restoration:


Create a user: (Execute SQL in sys)
Create user userName identified by passWord;
