Just for Refresh : Steps to upgrade Oracle from 11.1.0.6.0 to 11.1.0.7.0


steps to upgrade 11.1.0.6.0 to 11.1.0.7.0

Step1:

using winSCP or anyother tool copy the patch file p6890831_111070_Linux-x86-64.zip to the environment from the machine where you are having patch file.

Step2:
login : oracle
password:
Uncompress the binary source
$unzip p6890831_111070_Linux-x86-64.zip
Example:-
After unzipping , you can find the below folder Disk1
c111ptqhdd009: /home/oracle
$ cd /oracle/app/patches/
c111ptqhdd009: /oracle/app/patches
$ ls
Disk1 p6890831_111070_Linux-x86-64.zip

Step3:
Bring down the application

Step4:
login : oracle
password:
Bring down the database
sqlplus ‘/as sysdba’
sql>shutdown immediate;
sql>exit
>ps -ef |grep pmon

Make sure that oracle is not running
>lsnrctl stop
>lsnrctl status
Make sure that the listener is not running.
Take a cold database backup
Controlfiles, datafiles, redo logs, archive files, tempfiles must be included in the backup. If the files are in different paths, the same has to be backedup.
>mkdir /backup_date
>cp /App1/oracle/oradata/orcl/*.* /backup/backup_date
>cd $ORACLE_HOME/dbs
>cp inittest.ora inittest.ora_bkpdate
>cp spfiletest.ora spfiletest.or_bkpdate
>cp orapwtest.ora orapwtest.ora_bkpdate

Oracle : Move datafile to different location


From time to time a DBA might need move an Oracle database datafile from one location to another. Reasons for this might include: I/O balancing for performance reasons, or to rectify incorrect naming standards.

Choose one of the following procedures based on the log mode of your database (select log_mode from sys.v_$database):

Database is in ARCHIVELOG mode

  • Take the datafile offline with the “ALTER DATABASE DATAFILE ‘/old/location’ OFFLINE;” command.
  • Copy or move the datafile to its new location. On Unix this can be done with the “dd” command.

Example:

dd if=/old/location of=/new/location bs=4096

SQL> ALTER DATABASE RENAME FILE '/old/location' TO '/new/location';
SQL> RECOVER DATAFILE '/new/location';
SQL> ALTER DATABASE DATAFILE '/new/location' ONLINE;

Database is in NOARCHIVELOG mode

  • Shutdown the database
  • Copy or move the datafile to its new location. On Unix this can be done with the “dd” command. Example:
dd if=/old/location of=/new/location bs=4096
  • Start SQL*Plus, do a “STARTUP MOUNT” and rename the file:
SQL> ALTER DATABASE RENAME FILE '/old/location' TO '/new/location';
SQL> ALTER DATABASE OPEN;
