11 - Major database release number
1 - Database maintenance release number
0 - Application server release number
1 - Component specific release number
0 - Platform specific release number
http://www.oracle.com/technology/software/products/database/index.html
1. Make sure the source environment is in stable state:
11.1.0.6 Startup Database
Alert log location: $ORACLE_BASE/diag/rdbms/aitmr93w/aitmr93w/trace
2. Download the 11gR2 software into the stage from where it needs to be installed.
3. Oracle Database Pre-installation Requirements
Checking the Hardware Requirements:-
The system must meet the following minimum hardware requirements:
1. Memory Requirements
1. At least 1 GB of RAM
# grep MemTotal /proc/meminfo
2. Determine the size of the configured swap space
# grep SwapTotal /proc/meminfo
The following table describes the relationship between installed RAM and the configured swap space requirement:
|-------------------------------------------------------|
|RAM | Swap Space |
|-------------------------------------------------------|
|Between 1 GB and 2 GB | 1.5 times the size of RAM |
|Between 2 GB and 16 GB | Equal to the size of RAM |
|More than 16 GB | 16 GB |
|-------------------------------------------------------|
3. To determine the available RAM and swap space, enter the following command:
# free
2. System Architecture
# uname -m
3. Disk Space Requirements
1. At least 1 GB of disk space in the /tmp directory
# df -h /tmp
If the free disk space available in the /tmp directory is less than what is required,
then complete one of the following steps:
a) Delete unnecessary files from the /tmp directory to meet the disk space
requirement.
b) Set the TMP and TMPDIR environment variables when setting the oracle
user’s environment.
2. To determine the amount of free disk space on the system, enter the following command:
# df -h
The following tables describe the disk space requirements for software files,
and data files for each installation type on Linux x86:
Installation Type Requirement for Software Files (GB)
Enterprise Edition 3.95
Standard Edition 3.88
Installation Type Disk Space for Data Files (GB)
Enterprise Edition 1.7
Standard Edition 1.5
Checking the Software Requirements:-
1. Operating System & Kernel Requirements
Oracle Enterprise Linux 4 Update 7
Oracle Enterprise Linux 5 Update 2
To determine the distribution and version of Linux installed, enter the following command:
# cat /proc/version
Alternatively, you can also enter the following command on some distributions of Linux:
# lsb_release -id
Oracle Enterprise Linux 4, and Red Hat Enterprise Linux 4:
2.6.9 or later
Oracle Enterprise Linux 5, and Red Hat Enterprise Linux 5:
2.6.18 or later
# uname -r

5. Pre-Upgrade steps:
5.1 Executing Pre-Upgrade Tool:
Before you start the upgrade process, to identify these checks.
5.1.1 Copy utlu112i.sql from 11gR2 OH i.e $ORACLE_BASE/db/11.2/rdbms/admin
to $HOME [ Assuming 11gR2 is Installed $ORACLE_BASE/db/11.2 ]
5.2.2 Login as SYSDBA
SQL> SPOOL $HOME/UpgDir/upgrade_info.log
SQL> @utlu112i.sql
SQL> SPOOL OFF
Review the log file and take necesary actions. Then continue with upgrade.
5.2 Correcting the Warnings [if any] found in above step
5.2.1 WARNING : Database is using an old time zone file version. After the upgrade,
patch the database time zone file version using DBMS_DST package to record latest time zone file version.
Sol: From Webiv Note: 815679.1
* For 11.1.0.6 and 11.1.0.7, after the upgrade to 11.2.0.1
use DBSM_DST to update to DSTv11 by following <<Note 977512.1>>
Updating the RDBMS DST version in 11gR2 (11.2.0.1 and up) using DBMS_DST
5.2.2 Database contains stale optimizer statistics.
EXEC DBMS_STATS.GATHER_DICTIONARY_STATS;
[OR]
EXEC DBMS_STATS.DELETE_SCHEMA_STATS('SYS');
5.2.3 WARNING: --> SYSTEM schema default tablespace has been altered.
.... The SYSTEM schema default tablespace is currently set to TOOLS.
.... Prior to upgrading your database please reset the
.... SYSTEM schema default tablespace to SYSTEM using the command:
.... ALTER USER SYSTEM DEFAULT TABLESPACE SYSTEM;
5.2.4. WARNING:--> recycle bin in use.
.... Your recycle bin turned on.
.... It is REQUIRED
.... that the recycle bin is empty prior to upgrading
.... your database.
.... The command: PURGE DBA_RECYCLEBIN
.... must be executed immediately prior to executing your upgrade.
5.3 Shutdown 11gR1 Database
5.4 Configuring 11gR2 Instance
5.4.1 Source 11gR2 instance
5.4.2 Copy parameter file form pfile location to 11gR2/dbs

SQL> SPOOL $HOME/UpgDir/postupgrade_status.log
SQL> @utlu112s.sql
Oracle Database 11.2 Post-Upgrade Status Tool 05-07-2010 01:08:37

7.2 Post-Upgrade Actions
Run catuppst.sql, located in the ORACLE_HOME/rdbms/admin directory, to
perform upgrade actions that do not require the database to be in UPGRADE mode:
SQL> SPOOL $HOME/UpgDir/postupgrade_status.log
SQL> @catuppst.sql
7.3 Compiling Invalid Objects:

7.4 Updating the RDBMS DST version in 11gR2 (11.2.0.1 and up) -- Webiv Note 977512.1
Oracle 11.2.0.1 has by default all RDBMS DST updates from DSTv1 to DSTv11 included in the software installation.
These files are found in $ORACLE_HOME/oracore/zoneinfo and have a prefix indicating the DST version.
7.4.1 check current RDBMS DST version and "DST UPGRADE STATUS".
conn / as sysdba
SELECT PROPERTY_NAME, SUBSTR(property_value, 1, 30) value
FROM DATABASE_PROPERTIES
WHERE PROPERTY_NAME LIKE 'DST_%'
ORDER BY PROPERTY_NAME;
Check that the output gives
-- PROPERTY_NAME VALUE
-- ------------------------------ ------------------------------
-- DST_PRIMARY_TT_VERSION <the old DST version number>
-- DST_SECONDARY_TT_VERSION 0
-- DST_UPGRADE_STATE NONE
-- DST_PRIMARY_TT_VERSION should match the value found when selecting
7.4.2 SELECT version FROM v$timezone_file;
VERSION
----------

7.4.3 Do the actual RDBMS DST version update of the database
7.4.3.1 Change DB into Upgrade Mode
conn / as sysdba
shutdown immediate;
startup upgrade;
set serveroutput on
purge dba_recyclebin;
7.4.3.2 Clean used tables
TRUNCATE TABLE SYS.DST$TRIGGER_TABLE;
TRUNCATE TABLE sys.dst$affected_tables;
TRUNCATE TABLE sys.dst$error_table;
7.4.3.3 start upgrade window
EXEC DBMS_DST.BEGIN_UPGRADE(<the new DST version number>);
SQL> EXEC DBMS_DST.BEGIN_UPGRADE(11);
SELECT PROPERTY_NAME, SUBSTR(property_value, 1, 30) value
FROM DATABASE_PROPERTIES
WHERE PROPERTY_NAME LIKE 'DST_%'
ORDER BY PROPERTY_NAME;
SELECT OWNER, TABLE_NAME, UPGRADE_IN_PROGRESS FROM ALL_TSTZ_TABLES where UPGRADE_IN_PROGRESS='YES';
7.4.3.4 Restart the Database
shutdown immediate
startup
set serveroutput on
7.4.3.5 Upgrade the tables who need action

The
instructions below are for installing version Java 7 Update 7 (7u7). If
you are installing another version, make sure you change the version
number appropriately when you type the commands at the terminal. Example: For Java 6u35 replace 7u7 with 6u35. Note that, as in the preceding example, the version number is sometimes preceded with the letter
