Upgrade your database from Oracle 10.2.0.4 to 11.2.0.4 database
Sharing real time knowledge,issues on Oracle DBA

1. Upgrade Procedure

      1. Current database version is 10.2.0.4.0 64 Bit
      2. Install 11.2.0.3 Software on current server
      3. Direct upgrade to 11.2.0.4

2. Download 11.2.0.4 software

Patch 10404530: 11.2.0.4.0 PATCH SET FOR ORACLE DATABASE SERVER
Platform: Linux x86-64

Download above software from Oracle Support and keep in a staging location

3. Check Kernel version & OS Version

2.6.32 or later
uname –a (Use this command to check Kernel version and OS version

4. Create new ORACLE_HOME location

mkdir -p /u01/app/oracle/product/11.2.0/db_1

4. Set Oracle Inventory

Edit /etc/oraInst.loc to point to /u01/app/oraInventory
mkdir -p /u01/app/oraInventory

5. Install 11.2.0.4 Enterprise edition Oracle software

Enable VNC, Enter following command on VNC to start OUI for installation
/u03/software/oracle11204/runInstaller

Use new ORACLE_HOME for 11.2.0.4 as /u01/app/oracle/product/11.2.0/db_1

6. Install Oracle Database 11g Products from the 11g Examples CD

Enable VNC, Enter following command on VNC to start Example Installer
/u03/stage/11203_sw/examples/runInstaller

7. Set the environment

export ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1
export PATH  = $ORACLE_HOME/bin: $ORACLE_HOME/perl/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib.


8. Take full backup before upgrade activity.
       RMAN and EXPDP
9. Apply recommended Patches for 11.2.0.4 ORACLE_HOME

Use Opatch to apply above patch

10. Apply 11.2.0.4 Performance patches:

11. Set the environment to Existing 10.2.0.4 Environment

Set SID,ORACLE_HOME,PATH,LD_LIBRARY_PATH

login to PROD database

12. Run Pre-Upgrade Information Tool in 10.2.0.4 database (Must)

sqlplus '/ as sysdba'
spool pre_upg_11204_info.log
@/u01/app/oracle/product/11.2.0/db_1/rdbms/admin/utlu112i.sql
spool off

Check the output of the Pre-Upgrade Information Tool in upgrade_info.log
Run utlrp.sql to fix invalid objects or components issue

Important: If you see a warning about the presence of the release 10g DMSYS schema in the database, then you must drop the DMSYS schema before proceeding with the upgrade. Better raise a SR with Oracle support for confirmation. This is one way. Without drop also we can proceed. Follow my next steps.

13.  Check timezone version of 10.2.0.4 database and 11.2.0.3 and compare if both are same

SQL> SELECT version FROM v$timezone_file;

   VERSION
   ---------
         4

Note: When upgrading from 10.1.0.x , 10.2.0.x or 11.1.0.x to 11.2.0.3: (1358166.1)

* For 10.2.0.2 , 10.2.0.3 , 10.2.0.4 or 10.2.0.5 there is no need to apply any patchset before upgrading to 11.2.0.3 Upgrade to 11.2.0.3.No need to apply DST patches on the 10.2.0.2 , 10.2.0.3 , 10.2.0.4 or 10.2.0.5 side first. You can skip any DST related upgrade instructions. The 11.2.0.3 RDBMS DST version after the upgrade to 11.2.0.3 will be the same DST version as used in 10.2.0.2 , 10.2.0.3 , 10.2.0.4 or

10.2.0.5.

* (recommended) update the 11.2.0.3 database(s) to DSTv14 (standard DST version of 11.2.0.3) by following Note 977512.1 Updating the RDBMS. DST version in 11gR2 (11.2.0.1 and up) using DBMS_DST from step 3a) using "14" as (<the new DST version number>) in that note. When going to

DSTv14 there is no need to apply any DST patch to the 11.2.0.3 home.

14. Upgrade 11.2.0.1 to 11.2.0.3 using Manual upgrade method

15. Get DBA_REGISTRY information

sqlplus '/ as sysdba'
select COMP_ID,COMP_NAME,VERSION,STATUS,MODIFIED from dba_registry;

16.  Purge Recycle bin

PURGE DBA_RECYCLEBIN;

17. Gather Dictionary stats

EXECUTE dbms_stats.gather_dictionary_stats;

18.  Shutdown PROD database listener and database

shut immediate
lsnrctl stop PROD

19. Copy of parameter files and edit for upgrade

Copy the init parameter file from 10.2.0.4 ORACLE_HOME/dbs into 11.2.0.4 ORACLE_HOME/dbs

Adjust the parameter file for the upgrade

Adjust initialization parameters that might cause upgrade problems.

• Remove obsolete initialization parameters based on pre-upgrade tool output
• Set the COMPATIBLE parameter if not already explicitly set

Adjust the parameter file for the upgrade

Adjust initialization parameters that might cause upgrade problems.

• Remove obsolete initialization parameters based on pre-upgrade tool output
• The DIAGNOSTIC_DEST initialization parameter replaces the USER_DUMP_DEST, BACKGROUND_DUMP_DEST
• Set the COMPATIBLE parameter if not already explicitly set

If you are upgrading from 10.1.0.x or 10.2.0.x then you can leave the COMPATIBLE parameter set to it's current value until the upgrade has

been completed successfully. This will avoid any unnecessary ORA-942 errors from being reported in SMON trace files during the upgrade

(because the upgrade is looking for 10.2 objects that have not yet been created).

grep -i comp initPROD.ora
*.compatible = 10.2.0.4.0

20. Prepare Oracle environment

export ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1
export PATH  = $ORACLE_HOME/bin: $ORACLE_HOME/perl/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib.
export ORACLE_BASE=/u01/oracle/PROD/

21. Verify /etc/oratab

PROD should point to /u01/app/oracle/product/11.2.0/db_1 as ORACLE_HOME

22. Run upgrade scripts in VNC session

cd $ORACLE_HOME/rdbms/admin
sqlplus '/ as sysdba'
STARTUP UPGRADE

Monitor the alert log file and check for any errors.

SPOOL upgrade_PROD_11203.log
@catupgrd.sql

The output is at:
/u01/app/oracle/product/11.2.0/db_1/rdbms/admin/upgrade_PROD_11203.log

STARTUP

Post-Upgrade Status Tool.
@utlu112s.sql

Verify the results, and if there any errors, must be resolved at this point.

@catuppst.sql

Identifying Invalid Objects:

Any invalid SYS/SYSTEM objects found before upgrading the database are stored in the table named registry$sys_inv_objs. Any invalid non-SYS/SYSTEM objects found before upgrading the database are stored in registry$nonsys_inv_objs.To identify any new invalid objects due to the upgrade

After the upgrade, run ORACLE_HOME/rdbms/admin/utluiobj.sql

Compile invalids:

@?/rdbms/admin/utlrp.sql

23. Post Upgrade Steps

24. Actions For DST Updates When Upgrading To Or Applying The 11.2.0.3 Patchset [ID 1358166.1]

A) Applying 11.2.0.3 on 11.2.0.2 or 11.2.0.1

 Check the current version of the 11.2.0.2 or 11.2.0.1 Oracle RDBMS time zone definitions - this needs to be done for ALL databases in the

11.2.0.2 or 11.2.0.1 home:

SQL> conn / as sysdba
Connected.

SQL>SELECT version FROM v$timezone_file;

VERSION
----------
14

A.1)  The result is lower than 14 for all databases (typically 11 or 14)

Note : Every database in 11.2.0.1 home needs to be checked, if one or more has a result higher than 14 you need to follow step A.3)

If your current RDBMS time timezone version is  lower than 14 ,  install 11.2.0.3 in a new home and update the 11.2.0.2 or 11.2.0.1 databaseto 11.2.0.3 You can skip any DST related sections in the patchset documentation , there is no need to apply DST patches or check for DST issues for theupdate to 11.2.0.3
The 11.2.0.3 RDBMS DST version after the update to 11.2.0.3 will be the same as your 11.2.0.2 or 11.2.0.1 system.After the upgrade to 11.2.0.3 you can* (recommended) update to DSTv14 (standard DST version of 11.2.0.3) by following Note 977512.1 Updating the RDBMS DST version in 11gR2
(11.2.0.1 and up) using DBMS_DST from step 3a) onwards, when going to DSTv14 there is no need to apply any DST patch to the 11.2.0.3 home

* (optional) update to a higher DST than DSTv14 version if this is needed.

The latest available DST patch is found in Note 412160.1 Updated DST transitions and new Time Zones in Oracle Time Zone File patches

A.2)  The result is 14 for all databases
Note : Every database in 11.2.0.2 or 11.2.0.1 home needs to be checked, if one or more has a result higher than 14 you need to follow steps.

A.3)

If your current RDBMS time timezone version is 14 , install 11.2.0.3 in a new home and update the 11.2.0.2 or 11.2.0.1 database to 11.2.0.2.

You can skip any DST related sections in the patchset documentation , there is no need to apply DST patches or check for DST issues for theupdate to 11.2.0.3

The 11.2.0.3 RDBMS DST version after the update to 11.2.0.3 will be 14.

(optionally) After the upgrade to 11.2.0.3 you can check if there is a newer DST version out and , if needed, update every database to thisDST version. The latest available DST patch is found in Note 412160.1 Updated DST transitions and new Time Zones in Oracle Time Zone File

patches:

A.3)  The result is higher than 14 for one or more databases
If your current RDBMS time timezone version is higher then 14, you need to re-apply the same RDBMS DST version as found in step A) afterinstalling the 11.2.0.3 software . Or in other words, you need to apply the 11.2.0.3 RDBMS DST patch for the same DST version before openingthe database in the new 11.2.0.3 software home.

Apply the 11.2.0.3 RDBMS DST patch after installing the 11.2.0.3 software with the Oracle Universal installer.

If you also need to patch the OJVM then we suggest to apply the latest DST OJVM fix for 11.2.0.3, even if your current RDBMS DST patch is lower. This is best done right after installing the RDBMS DST patch, no need to follow the OJVM DST patch readme instructions as there is no database yet.

For the actual OJVM and RDBMS DST patches for your 11.2.0.3 release please see Note 412160.1 Updated Time Zones in Oracle Time Zone File


After installing the same RDBMS (and the OJVM - which may be the lastest/higher than the RDBMS DST version) DST patch in the 11.2.0.3 ORACLE_HOME upgrade to 11.2.0.3 without any action on TSLTZ or TSTZ data. Follow the upgrade or patchset apply instructions, you can skip any DST related sections.

The 11.2.0.3 RDBMS DST version after the upgrade to 11.2.0.2 will be the same DST version as used in the 11.2.0.2 or 11.2.0.1 Oracle RDBMS.

(optionally) After the upgrade to 11.2.0.3 you can check if there is a newer DST version out and , if needed, update every database to this DST version. The latest available DST patch is found in Note 412160.1 Updated DST transitions and new Time Zones in Oracle Time Zone File


25. Do the actual RDBMS DST version update of the database using DBMS_DST:

conn / as sysdba
shutdown immediate;
startup upgrade;
set serveroutput on

-- check if previous prepare window is ended

SELECT PROPERTY_NAME, SUBSTR(property_value, 1, 30) value
FROM DATABASE_PROPERTIES
WHERE PROPERTY_NAME LIKE 'DST_%'
ORDER BY PROPERTY_NAME;

-- output should be
-- PROPERTY_NAME VALUE
-- ---------------------------- ------------------------------
-- DST_PRIMARY_TT_VERSION <the old DST version number>
-- DST_SECONDARY_TT_VERSION 0
-- DST_UPGRADE_STATE NONE

-- If DST_UPGRADE_STATE is "PREPARE" then you did not ended
-- the prepare window in step 3)

-- If there are objects containing TSTZ data in recycle bin,
-- please purge the bin now.
-- Otherwise dbms_dst.begin_upgrade will report "ORA-38301: Can not perform DDL/DML over objects in Recycle Bin".

purge dba_recyclebin;

-- clean used tables

TRUNCATE TABLE SYS.DST$TRIGGER_TABLE;
TRUNCATE TABLE sys.dst$affected_tables;
TRUNCATE TABLE sys.dst$error_table;

-- this alter session might speed up DBMS_DST on some db's
-- see Bug 10209691

alter session set "_with_subquery"=materialize;

-- to avoid the issue in note 1407273.1
alter session set "_simple_view_merging"=TRUE;

-- start upgrade window

EXEC DBMS_DST.BEGIN_UPGRADE(14);

-- the message
-- "An upgrade window has been successfully started."
-- will be seen

-- check if this select

SELECT PROPERTY_NAME, SUBSTR(property_value, 1, 30) value
FROM DATABASE_PROPERTIES
WHERE PROPERTY_NAME LIKE 'DST_%'
ORDER BY PROPERTY_NAME;

-- gives this output:
-- PROPERTY_NAME VALUE
-- --------------------------- ------------------------------
-- DST_PRIMARY_TT_VERSION <the new DST version number>
-- DST_SECONDARY_TT_VERSION <the old DST version number>
-- DST_UPGRADE_STATE UPGRADE

-- Optionally you can check what user tables still need to be updated using DBMS_DST.UPGRADE_DATABASE
-- BEGIN_UPGRADE upgrades system tables that contain TSTZ data and marks user tables (containing TSTZ data) with the UPGRADE_IN_PROGRESS

property.
-- even if this select gives no rows you still need to do to the rest of the steps
-- it simply gives an indication of how many user objects need to processed in the later steps
-- some oracle provided users may be listed here, that is normal

SELECT OWNER, TABLE_NAME, UPGRADE_IN_PROGRESS FROM ALL_TSTZ_TABLES where UPGRADE_IN_PROGRESS='YES';

-- restart the database

shutdown immediate
startup

alter session set "_with_subquery"=materialize;
alter session set "_simple_view_merging"=TRUE;

-- now upgrade the tables who need action

set serveroutput on
VAR numfail number
BEGIN
DBMS_DST.UPGRADE_DATABASE(:numfail,
parallel => TRUE,
log_errors => TRUE,
log_errors_table => 'SYS.DST$ERROR_TABLE',
log_triggers_table => 'SYS.DST$TRIGGER_TABLE',
error_on_overlap_time => FALSE,
error_on_nonexisting_time => FALSE);
DBMS_OUTPUT.PUT_LINE('Failures:'|| :numfail);
END;
/

-- ouput of this will be a list of tables like:

-- Table list: SYSMAN.AQ$_MGMT_NOTIFY_QTABLE_S
-- Number of failures: 0
-- ....
-- Table list: SYSMAN.MGMT_PROV_ASSIGNMENT
-- Number of failures: 0
-- Table list: SYSMAN.MGMT_CONFIG_ACTIVITIES
-- Number of failures: 0
-- Failures:0

-- if there where no failures then end the upgrade.

VAR fail number
BEGIN
DBMS_DST.END_UPGRADE(:fail);
DBMS_OUTPUT.PUT_LINE('Failures:'|| :fail);
END;
/

-- output that will be seen:
-- An upgrade window has been successfully ended.
-- Failures:0

-- last checks

SELECT PROPERTY_NAME, SUBSTR(property_value, 1, 30) value
FROM DATABASE_PROPERTIES
WHERE PROPERTY_NAME LIKE 'DST_%'
ORDER BY PROPERTY_NAME;

-- needed output:
-- PROPERTY_NAME VALUE
-- ---------------------------- ------------------------------
-- DST_PRIMARY_TT_VERSION <the new DST version number>
-- DST_SECONDARY_TT_VERSION 0
-- DST_UPGRADE_STATE NONE


SELECT * FROM v$timezone_file;

-- needed output:
-- FILENAME VERSION
-- ------------------ ----------
-- timezlrg_<new version>.dat <new version>

-- if registry$database exists then update this static table also with the new DST version
-- this table is used during upgrade and contians the DST version from before the upgrade
-- this update is mainly to avoid confusion when people notice this has a lower version

select TZ_VERSION from registry$database;

update registry$database set TZ_VERSION = (select version FROM v$timezone_file);
commit;

26. Configuring Fine-Granined Access to External Network services After upgrading Oracle database

Create ACLs as per note id: 958129.1:

SQL> SELECT OWNER, REFERENCED_NAME FROM DBA_DEPENDENCIES
WHERE referenced_name IN ('UTL_TCP','UTL_SMTP','UTL_MAIL','UTL_HTTP','UTL_INADDR')
AND owner NOT IN ('SYS','PUBLIC','ORDPLUGINS');

exec DBMS_NETWORK_ACL_ADMIN.CREATE_ACL();
exec DBMS_NETWORK_ACL_ADMIN.ADD_PRIVILEGE();
exec DBMS_NETWORK_ACL_ADMIN.ASSIGN_ACL();

COMMIT;

SQL> select * from dba_network_acls;

27. Upgrade Oracle Text - None

After an upgrade to the new Oracle Database 11g release, copy the following files from the previous Oracle home to the new Oracle home:

■ Stemming user-dictionary files
■ User-modified KOREAN_MORPH_LEXER dictionary files
■ USER_FILTER executables

These files affect all databases installed in the given Oracle home.

You can obtain a list of these files by doing the following:
1. Looking at $ORACLE_HOME/ctx/admin/ctxf102.txt
2. Executing $ORACLE_HOME/ctx/admin/ctxf102.sql as database user SYS,SYSTEM, or CTXSYS

28. Configure and Start new database listener

Get your listener.ora and tnsnames.ora files from Old Home to New home
Set the TNS_ADMIN environment variable to the directory where you got your listener.ora and tnsnames.ora files.

Start listener
