HOW TO PERFORM BACKUP AND RESTORE USING EXPDP/IMPDP UTILITY|| ORACLE 12C || DBA FROM INDIA

Hi There In this video I have tried to explain about the EXPDP/IMPDP utility of oracle Database with practical. I Am sharing the steps below which I have performed. EXPORT/IMPORT (EXPDP/IMPDP): ========================== 1. Create an user 2. import some data for the schema. 3. take export backup of the schema. 4. drop the schema. 5. import the schema from the export backup. steps: ===== 1. Create an user ================== create user TEST_02 identified by "Abc#123"; grant connect,create session, resource to test_02; grant dba to test_02; 2. import some data for the schema. =================================== connect TEST_02/Abc#123 create table test_tbl ( id number, name varchar2(20)); insert into test_tbl values(1, 'A'); insert into test_tbl values(2, 'B'); insert into test_tbl values(3, 'C'); insert into test_tbl values(4, 'D'); insert into test_tbl values(5, 'E'); insert into test_tbl values(6, 'F'); insert into test_tbl values(7, 'G'); commit select * from test_tbl; 3. take export backup of the schema. ==================================== create a directory: ------------------- CREATE [OR REPLACE] DIRECTORY directory_name AS 'path_name'; CREATE OR REPLACE DIRECTORY EXPDP AS '/u02/export_bkp'; nohup expdp \'/ as sysdba\' directory=EXPDP dumpfile=TEST_02.dmp logfile=test_02_bkp.log schemas=TEST_02 & tail -20f test_02_bkp.log 4. drop the schema =================== drop user TEST_02 cascade; 5. import the schema from the export backup. ============================================ nohup impdp \'/ as sysdba\' directory=EXPDP dumpfile=TEST_02.dmp logfile=import_test_02_bkp.log schemas=TEST_02 & select count(*) from TEST_02.TEST_TBL; COUNT(*) ---------- 7 select username,account_status from dba_users where username like '%TEST_02%'; select * from TEST_02.TEST_TBL; #backup #backupandrestore #oracle #oracledba #expdp #impdp #exportimport #12c #dba #oracledatabasetutorial #practical
