How to find the tapes needed for restore if you are using RMAN catalog to write directly to tape?

If you are using the RMAN and using the RMAN catalog to write directly to tape you can use the following query to find the tapes needed to restore or the tapes that were used.

# The following example find the tapes used to backup b/w 10-Jun-2008 4:00 AM and 11-Jun-2008 4:00 AM by specifying the database name or DB ID

$ sqlplus rmancatalog/rmancatalog
SQL> select distinct p.MEDIA
from rc_backup_piece p, rc_database d
where d.NAME = ‘TEMP’
– OR d.dbid = 3903930932
and p.COMPLETION_TIME >= TO_DATE(‘10-JUN-2008 04:00′, ‘DD-MON-YYYY HH24:MI’)
and p.COMPLETION_TIME <= TO_DATE(‘11-JUN-2008 04:00′, ‘DD-MON-YYYY HH24:MI’)
and p.db_id = d.dbid;

How to change SYSMAN password in OEM (OMS)

To change the Sysman password:
1. Stop the OMS instances that are associated with the repository
a. opmnctl stopall

2. Change the sysman password in the database:
a. Logon to sqlplus as a dba user
b. Issue the command: alter user sysman identified by newpassword;
c. Exit Sqlplus

3. On each management server host, cd to the OMS $ORACLE_HOME/sysman/config directory
a. backup the emoms.properties file
b. edit the emoms.properties file and modify the parameters;
eml.mntr.emdRepPwd=new_password
oracle.sysman.eml.mntr.emdRepPwdEncrypted=FALSE

NOTE: When you restart the OMS, the FALSE setting will change to TRUE and the password will become encrypted in the file

4. Still on Management Repository host, cd to the AGENT_HOME/bin and stop the agent:
./emctl stop agent
5. Next, cd to the AGENT_HOME/sysman/emd directory
a. Edit the targets.xml file and modify the oracle_emrep target definition with the following in bold:
<Target TYPE=”oracle_emrep” NAME=”Management Services and Repository” VERSION=”1.0″>
<Property NAME=”MachineName” VALUE=”host.us.oracle.com”/>
<Property NAME=”Port” VALUE=”1521″/>
<Property NAME=”SID” VALUE=”sid”/>
<Property NAME=”UserName” VALUE=”552f2080d6d8c3c6″ ENCRYPTED=”TRUE”/>
<Property NAME=”password” “newpassword” ENCRYPTED”FALSE”/>
..
..
b. Save the file. The TRUE value will change to FALSE and the newpassword will become encrypted when you restart the Agent.

6. Issue the command (from the Agent O_H/bin):
./emctl start agent

7. Restart each of the OMS’s
emctl start oms

8.Start the OMS instances that are associated with the repository
opmnctl startall

Note that after change all the config files shown in the document, the OEM still had issues to connect to the repository due to the sysman user been locked. After unlock the sysman account everything was back to normal.

How does one trace a session based on user

ora_username VARCHAR2(30) DEFAULT NULL;
os_username VARCHAR2(30);
v_sid NUMBER;
v_serial NUMBER;
v_program VARCHAR2(48);
v_numuser NUMBER;
CURSOR c1 IS
SELECT sid, serial#, osuser, machine, program
FROM v$session
WHERE audsid = userenv(’sessionid’)
– and upper(machine) like ‘ABC123′
and username = ‘EPCBATCH’;
BEGIN
OPEN c1;
FETCH c1 INTO v_sid, v_serial, osuserid, machinename,v_program;
IF c1%FOUND THEN
DBMS_SESSION.set_sql_trace (TRUE);
END IF;
