Enterprise Manager - Database Control Repository
Applies to:
Enterprise Linux – Version: 5

To recreate the
Database Control Repository do the following simple steps:
Make sure that the Database
environment is properly set.
To check ORACLE_HOME and ORACLE_SID
values properly set:
[oraprod@ebsdev ~]$ echo $ORACLE_HOME
/d01/oracle/TEST/db/tech_st/11.1.0
[oraprod@ebsdev ~]$ echo $ORACLE_SID
TEST
[oraprod@ebsdev ~]$ sqlplus / as sysdba
SQL> drop user sysman
cascade;
SQL> drop role mgmt_user;
SQL> drop user mgmt_view
cascade;
SQL> drop public synonym
mgmt_target_blackouts;
SQL> drop public synonym
setemviewusercontext;
SQL> drop public
synonym mgmt_availability;
SQL> DECLARE
CURSOR c1 IS
SELECT owner, synonym_name name
FROM dba_synonyms
WHERE table_owner = 'SYSMAN';
BEGIN
FOR r1 IN c1 LOOP
IF r1.owner = 'PUBLIC' THEN
EXECUTE IMMEDIATE 'DROP PUBLIC SYNONYM '||r1.name;
ELSE
EXECUTE
CURSOR c1 IS
SELECT owner, synonym_name name
FROM dba_synonyms
WHERE table_owner = 'SYSMAN';
BEGIN
FOR r1 IN c1 LOOP
IF r1.owner = 'PUBLIC' THEN
EXECUTE IMMEDIATE 'DROP PUBLIC SYNONYM '||r1.name;
ELSE
EXECUTE
IMMEDIATE 'DROP SYNONYM '||r1.owner||'.'||r1.name;
END IF;
END LOOP;
END;
/
exit
END IF;
END LOOP;
END;
/
exit
Remove the following
directories:
[oraprod@ebsdev ~]$ rm -rf
$ORACLE_HOME/host_sid/
[oraprod@ebsdev ~]$ rm –rf
$ORACLE_HOME/oc4j/j2ee/OC4J_DBConsole_host_sid
To create the DB control and repository:
[oraprod@ebsdev ~]$ emca
-config dbcontrol db -repos create
