1. Introduction
Upgrading from Oracle database from 10.2.0.1 to 10.2.0.2 on Sun OS using DBUA is as we upgrade on other platforms using DBUA on other platforms. Following are the differences in various platforms
• Setting operating system parameters like kernel configuration,
• Checking memory,
• Disks and other resources.
.
2. Assumption
• The Sun Solaris (UNIX) Operating System is installed on the Sun Solaris Hardware with all the required resources.
• All the required file systems are created with sufficient disk space as required for Oracle Applications Software and Database.
• The Staging area for Oracle Database is created
• Application DBA performing installation has a graphical interface with the Sun OS system. We are going to use xmanger 2.0 software for accessing the Sun OS from remote client.
• The openwin - xterm process is running on the server.
.
3 Pre – Requisite
Before Starting Upgrading process we have to apply two important patches in the Source
1. 10g Release 2 interoperability patch for 11.5.10 (4653225)
2. 5478710 (TXK (FND & ADX) AUTOCONFIG ROLLUP PATCH O
Refer Metalink Note 362203.1
4. Creating Staging Area on the Server
Staging Area is an area from where you will stage the Oracle 10GR2/Companion Software and run the installation program. Staging area for Oracle 10GR2 requires around 3-4 GB of disk space.
Mount the DVD’s of Oracle 10GR2/Download from oracle websites otn.oracle.com on the server and copy the DVD’s in the staging location.
Create directories named as the stage (this you can get from the DVD’s component.label file).
Copy all the DVD’s of similar components in same stage area.
Stage No. of DVD’s DVD Contents
Oracle11 Software 1 Disk1 /d33/stage
Oracle Companion 1 Disk2 d33/stage /stage1
.
5. Checking the Sun Operating System
System and hardware Configuration:
Hardware Status: sun4 (UNIX command; ‘arch’)
Operating System: SunOS 5.11 Generic sun4u sparc SUNW, Sun-Fire-V240 (UNIX command; ‘uname –a’).
CPU: 2 CPU’s. Each having the sparcv9 processor operates at 1503 MHz and has a sparcv9 floating point processor (UNIX command; ‘psrinfo –v’).
Memory size: 5120 Megabytes (UNIX command; ‘prtconf
grep size’).
Swap Total: (45440k bytes allocated + 4032k reserved = 49472k used) 14468936k available, i.e., 14GB (UNIX command; ‘swap –s’).
Check file System mounted and its respective size (UNIX command; ‘df -h’).
6. Create base directories for Oracle 10GR2 installation
From the mounted file system decide which file system will hold the database tier
For Ex:
/d35 – 32 GB – Oracle 10G Database Software (ORACLE_10GHOME RDBMS,)Create directory “/d35/ora10G/10.2.0”
7. Create OS group and Users and granting required privileges and file permissions
Create operating system group “DBA” and OS users “ora10G” for database tier . Note that we are planning to upgrade database tier owned by “oracle” user but both on the same host / system. But new Oracle_10G Home owner and source Oracle_9i Home owner should fall under same group.
Check the group created in “/etc/group”
# cat /etc/group
grep dba
dba::110:
Create Unix Users “oracle ”
Add these lines in “/etc/passwd” file:
ora10G:x:113:110::/orahome/ora10g:/bin/sh
Add these lines in “/etc/shadow” file:
Ora10g:30oQlK30ch6xY:13187::::::
Note that the user id is always unique and also the home directory given is the base directory as created above.
Give ownership of “/d35/ora10G” to “ora10G” .
# chown -R ora10G:dba /d35/ora10G
# ls -lrt /d35
/u01:
total 18
drwx—— 2 root root 8192 Jan 13 13:16 lost+found
drwxr-xr-x 2 oracle dba 512 Jan 23 12:34 ora10G
Give full file permissions on the staging area of Oracle Applications. Give “777” privileges on the staging area. Some unzip files are not able to get unzipped and then the installation gives error.
# pwd
/u06/stage
# ls
install runInstaller stage1
doc response stage welcome.html
#
# chmod -R 777 *
# pwd
/u06/stage
#
.

you will get the follwing output $ sqlplus “/as sysdba” SQL*Plus: Release 10.2.0.1.0 - Production on Wed May 23 13:19:31 2007 Copyright (c) 1982, 2005, Oracle. All rights reserved. Connected to an idle instance:Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - 64bit ProductionWith the Partitioning, OLAP and Data Mining options SQL>
9.15 Before you Begin Up gradation in Source Database
a. Log in to the system as the owner of the new 10gR2 ORACLE_HOME and copy the following files from the 10gR2 ORACLE_HOME/rdbms/admin directory to a directory outside of the Oracle home, such as the /tmp directory on your system: ORACLE_HOME/rdbms/admin/utlu102i.sql ORACLE_HOME/rdbms/admin/utltzuv2.sql Make a note of the new location of these files.
.
b. Login as ORACLE_SOURCE home owner. Go to /var/opt/oracle/oratab remove the comment and startup the database. Now you connect as sys owner from location where you have copied utlu102i.sql and utltzuv2.sql in sqlplus $ sqlplus “/as sysdba” SQL>@ utlu102i.sqlSQL> spool off
c. The above sql generate output file called updatelog.lst review the output made the changes accordingly in target init.ora .SQL>@ utltzuv2.sqlSQL> spool off The above sql generate output file called timezone.log review the output and change accordingly .
.
d. Check for the deprecated CONNECT Role After upgrading to 10gR2, the CONNECT role will only have the CREATE SESSIONprivilege; the other privileges granted to the CONNECT role in earlier releases will be revoked during the upgrade.
To identify which users and roles in your database are granted the CONNECT role, use the following query:
SELECT grantee FROM dba_role_privs
WHERE granted_role = ‘CONNECT’ and grantee NOT IN ( ‘SYS’, ‘OUTLN’, ‘SYSTEM’, ‘CTXSYS’, ‘DBSNMP’, ‘LOGSTDBY_ADMINISTRATOR’, ‘ORDSYS’, ‘ORDPLUGINS’, ‘OEM_MONITOR’, ‘WKSYS’, ‘WKPROXY’, ‘WK_TEST’, ‘WKUSER’, ‘MDSYS’, ‘LBACSYS’, ‘DMSYS’, ‘WMSYS’, ‘OLAPDBA’, ‘OLAPSVR’, ‘OLAP_USER’, ’OLAPSYS’, ‘EXFSYS’, ‘SYSMAN’, ‘MDDATA’, ’SI_INFORMTN_SCHEMA’, ‘XDB’, ‘ODM’);
If users or roles require privileges other than CREATE SESSION, then grant the specific required privileges prior to upgrading. The upgrade scripts adjust the privilegesfor the Oracle-supplied users.
.
e. In Oracle 9.2.x and 10.1.x CONNECT role includes the following privileges:
SELECT GRANTEE,PRIVILEGE FROM DBA_SYS_PRIVSWHERE GRANTEE=’CONNECT’ ;
GRANTEE PRIVILEGE—————————— —————————CONNECT CREATE VIEWCONNECT CREATE TABLECONNECT ALTER SESSIONCONNECT CREATE CLUSTERCONNECT CREATE SESSIONCONNECT CREATE SYNONYMCONNECT CREATE SEQUENCECONNECT
CREATE DATABASE LINK In Oracle 10.2 the CONNECT role only includes CREATE SESSION privilege.
.
f. Create the script for dblink incase of downgrade of the database. During the upgrade to 10gR2, any passwords in database links will be encrypted. To downgrade back to the original release, all of the database links with encrypted passwords must be dropped prior to the downgrade. Consequently, the database links will not exist in the downgraded database. If you anticipate a requirement to be able to downgrade back to your original release, then save the information about affected database links from the SYS.LINK$ table, so that you can recreate the database links after the downgrade.
.
g. Following script can be used to construct the dblink.
SELECT‘create ‘
DECODE(U.NAME,’PUBLIC’,'public ‘)
’database link ‘
CHR(10)
DECODE(U.NAME,’PUBLIC’,Null, U.NAME
’.')
L.NAME
chr(10)
’connect to ‘
L.USERID
‘ identified by ”’
L.PASSWORD
”’ using ”’
L.host
””
chr(10)
’;’ TEXTFROM sys.link$ L, sys.user$ UWHERE L.OWNER# = U.USER# ;
.
h. Check the invalid objects in source instance using the following qyery :-
spool invalid_pre.lstselect substr(owner,1,12) owner, substr(object_name,1,30) object, substr(object_type,1,30) type, status from dba_objects where status <>’VALID’;
spool off
Compile all the invalid objects using Run the following script and then requery invalid objects: This script must be run as a user with SYSDBA privs using SQL*Plus:
$ cd $ORACLE_HOME/rdbms/admin
$ sqlplus ‘/as sysdba’
SQL> @utlrp.sql
Even compile all the objects using Adamin utility of Oracle E –Business Suit .
.
i. Take Complete Backup of source Application and Database
9.16 Copy the Important Parameter files
a. Login to Source ORACLE_HOME $ cd $ORACLE_HOME/dbsCopy init
Copy tnsnames.ora and listener.ora to target TNS_ADMIN directory
b. Made changes in init
.

11a Errors Encountered and the Solution
a. While running runInstaller Script encountered the following errors :- ./runInstaller: /backup/database/install/.oui: cannot execute This error was due to bad media, So I downloaded following files from otn.oracle.com
1. 10Gr2_db_sol.cpio (Oracle 10GR2 Software )
2. 10Gr2_companion_sol.cpio (Oracle Companion Software)
Create Stage directory in any mount point give e.g. /d33/stage 777 permission to that directory # cat 10Gr2_db_sol.cpio
cpio –icd
It will extract entire software under stage directory.
Create Stage1 directory under stage directory e.g. d33/stage /stage1 give 777 permission to that directory
# cat 10Gr2_companion_sol.cpio
cpio –icd
It will extract entire software under stage directory.
b. While Running DBUA I have found the following errors :-
This is due to target and the source database owner is not in same group
Login as root; Example source oracle database owner group is dba , so change it accordingly .
# usermod -g dba ora10g
Login as ora10g owner and execute the following command
$cd $ORACLE_HOME
$ ls -l `find . ! -user ora10g`
In my system it gave the following output
-rwsr-x— 1 root dba 69028 2006-07-17 21:20 ./bin/extjob*
-rwsr-s— 1 root dba 18845 2006-06-21 09:13 ./bin/nmb*
-rwsr-s— 1 root dba 19999 2006-06-21 09:13 ./bin/nmo*
-r-sr-s— 1 root dba 14456 2006-02-04 21:57 ./bin/oradism*
-rw-r—– 1 root dba 1534 2005-12-22 13:39 ./rdbms/admin/externaljob.ora
Change ownership to the Oracle_10g Home using following command
#chown –R ora10g:dba /
$ cd $ORACLE_HOME/rdbms/lib
$mv config.o config.o.bkpEdit config.s file
and change the lines /* 0×0008 15 */ .ascii “v2dba”/* 0×0014 20 */ .align 8.L13:/* 0×0014 22 */ .ascii “v2dba”to/* 0×0008 15 */ .ascii “dba”/* 0×0014 20 */ .align 8 .L13:/* 0×0014 22 */ .ascii “dba”$Edit env_rdbms.mk From : KPIC_OPTION=-K PICTo : KPIC_OPTION=-xarch=v9 -K PIC$ make -f ins_rdbms.mk config.o ioracleIt has solved the problem
