Objective is to recover a table using the database and archive log backup with the help of timestamp and backup destination.
Here, As an example we have an database user “pop”. Under the user pop there is a table named “teams”.
Step 1: Connect as user pop and view the table TEAMS
SQL> conn pop/pop
Connected.
SQL> select count(*) from teams;
COUNT(*)
———-
620
Step 2: Take the time for recovery purpose.
SQL> select to_char(sysdate,’dd-mm-yyyy hh24:mi:ss’) “now” from dual;
now
——————-
23-01-2023 23:52:25
Step 3: Make sure archivelog is enabled or else enable archivelog.
SQL> archive log list;
Database log mode Archive Mode
Automatic archival Enabled
Archive destination USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence 1
Next log sequence to archive 2
Current log sequence 2
Step 4: Take a full backup of database and archivelog.
