————- Drop Database Manually Oracle ———————
1. First get the datafiles, control files and redo log files location
Login to sqlplus as sysdba and execute below script :
[sourcecode language="sql"]
DECLARE
TYPE string_arr IS TABLE OF VARCHAR2(1024);
file_list string_arr;
BEGIN
SELECT t.file_path BULK COLLECT
INTO file_list
FROM (SELECT NAME file_path
FROM V$DATAFILE
UNION
SELECT MEMBER file_path
FROM V$LOGFILE
UNION
SELECT NAME file_path
FROM v$controlfile
UNION
SELECT VALUE file_path
FROM v$parameter
WHERE NAME LIKE '%dest'
UNION
SELECT VALUE file_path
FROM v$parameter2
WHERE NAME = 'utl_file_dir'
UNION
SELECT '$ORACLE_BASE/admin/$ORACLE_SID' file_path
FROM dual
) t;
FOR i IN file_list.FIRST .. file_list.LAST LOOP
DBMS_OUTPUT.PUT_LINE('rm -f ' || file_list(i));
END LOOP;
END;
/
[/sourcecode]
It will generate output like
[sourcecode language="sql"] rm -f $ORACLE_BASE/admin/$ORACLE_SID rm -f +DATA/orcl/control01.ctl rm -f +DATA/orcl/control02.ctl rm -f +DATA/orclstandby/datafile/mgmt_ad4j_ts.270.805385125 rm -f +DATA/orclstandby/datafile/mgmt_ecm_depot_ts.268.805385111 rm -f +DATA/orclstandby/datafile/mgmt_tablespace.269.805385119 rm -f +DATA/orclstandby/redo01.log rm -f +DATA/orclstandby/redo02.log rm -f +DATA/orclstandby/redo03.log rm -f +DATA/orclstandby/sysaux01.dbf rm -f +DATA/orclstandby/system01.dbf rm -f +DATA/orclstandby/undotbs01.dbf rm -f +DATA/orclstandby/users01.dbf rm -f +FRA rm -f +FRA/orclstandby/onlinelog/group_4.368.801307819 rm -f +FRA/orclstandby/onlinelog/group_5.369.801307819 rm -f +FRA/orclstandby/onlinelog/group_6.370.801307821 rm -f +FRA/orclstandby/onlinelog/group_7.371.801307821 rm -f /oracle/app/oracle rm -f /oracle/app/oracle/admin/orcl/adump rm -f /oracle/app/oracle/diag/rdbms/orclstandby/orcl1/cdump rm -f /oracle/app/oracle/diag/rdbms/orclstandby/orcl1/trace rm -f 1 rm -f ?/dbs/arch rm -f [/sourcecode]
