Oracle Upgrade From 9i To 10g (Unix Platform)

Hi All,

Here is the procedure to upgrade the oracle 9i to 10g (9.2.0.6 to 10.2.0.4) ...

Some Notes You might need in between:

1) Note 841728 - 10.2: Solutions for installation and upgrade problems

2) Note 819830 - Oracle Database 10g: Additional Information on upgrade:UNIX

3) Note 886783 - Installing Oracle 9207 Client Software on UNIX

4) Note 600141 - Oracle9i: Automatic UNDO Management

5) Note 819829 - Oracle Instant Client Installation and Configuration on Unix

6) Note 830577 - Oracle Database 10g: ORA-21700 when upgrading to 10.1/10.2

7) Note 871735 - Current patch set for Oracle 10.2.0


Prerequisites for unix system :

1. Checking the Correct UNIX Users, Groups, and Authorizations:
Enter the following commands with user orasid:
touch /oracle/write_test
rm /oracle/write_test
umask 022
2) Checking the Directory Structure
Create the staging directory /oracle/stage/102_64.
Extract OR110264.SAR from CD 51031670 to /oracle/stage/102_64
Now perform the following:
cd /oracle/stage/102_64/database OR
cd /oracle/stage/102_64/database/Disk1
mv SAP SAP_ORIG

3) Download RDBMS_SAP_64.zip from note #819830 and copy it over to the
/oracle/stage /102_64/database directory

4) Extract the zip file:
cd /oracle/stage/102_64/database OR
cd /oracle/stage/102_64/database/Disk1
Unzip RDBMS_SAP_64.zip (You should now see the directory SAP extracted which
contains the updated version of SAP-specific files)

5) Check the Oracle inventory directory /var/opt/oracle/oraInst.loc
The default location for the Oracle inventory is $ORACLE_BASE/oraInventory

6) Create the empty Oracle home directory before starting the OUI.
/oracle//102_64

7) Running the Pre-Upgrade Script
Execute the following commands:
sqlplus /nolog
SQL> connect / as sysdba
SQL> spool /tmp/pre_upgrade.log
SQL> @/oracle/stage/102_64/database/Disk1/SAP/utlu102i.sql
SQL> spool off
SQL> exit
(You can check the results of the pre-upgrade script by looking at the log file /tmp/pre_upgrade.log.)

8) Checking the Prerequisites for the Oracle Universal Installer
Log in as the Oracle user ora.
Execute the following commands:
cd /oracle/stage/102_64/database/Disk1
./runInstaller –executeSysPrereqs
(If the OUI complains that the operating system version is not certified or
supported, you can ignore this.If OUI reports missing OS patches, you need to
apply these before you can continue. )

9) Download the latest version of the Oracle Client software ‒ OCL1020464.SAR
Before you start installing / extracting the Oracle client software please
shutdown the SAP application running on that host.Updating the Oracle client
software online (when the SAP system is still running) is not supported and may
result in system errors/inconsistencies.
Now do the following:
mv /oracle/client/10x_64 /oracle/client/10x_64_ORIG
mkdir /oracle/client/10x_64
IMPORTANT!! Go up to this directory, cd /oracle/client/10x_64
SAPCAR -xvf /tmp/OCL1020464.SAR
(Refer Note # 886783)

10) Execute the SQL script sapconn_role.sql as follows:
cp /oracle/stage/102_64/database/Disk1/SAP/sapconn_role.sql $ORACLE_HOME/dbs
cd $ORACLE_HOME/dbs
sqlplus /nolog @sapconn_role

11) 9. Migrating to Automatic Undo Management
Read SAP Note 600141,

12) 10. Stopping Statspack Reports (If running)
Log on as the user under which the statspack jobs run (usually PERFSTAT):
SQL> connect PERFSTAT/
SQL> select job, what from user_jobs;
This displays a list of the jobs that are currently entered under the user PERFSTAT.
Delete all jobs with the print job number :
SQL> connect PERFSTAT/
SQL> execute dbms_job.remove( );


13)Checking the SYSTEM and SYSAUX Tablespace for Free space
Make sure that the SYSTEM and SYSAUX tablespaces have at least between 500 MB and 750 MB freespace.
(If your source database is Oracle 9.2, there is no SYSAUX tablespace. In this case you can ignore references to the SYSAUX tablespace in this section. )
Check Space by:
brspace –f dbshow –c tsinfo –s SYSTEM
brspace –f dbshow –c tsinfo –s SYSAUX
If the size is less then 750 MB of freespace extend the tablespace.


14) Checking for Invalid Database Objects
a). Execute the following commands:
SQL> spool invalid_objects
SQL> select unique object_name, object_type, owner from dba_objects where status ='INVALID';
SQL> @?/rdbms/admin/utlrp.sql
SQL> select unique object_name, object_type, owner from dba_objects where status ='INVALID';
SQL> spool off
A) list of invalid objects before the upgrade is now generated.Invalid Objects Before upgrade
B) Check the list of invalid objects after the upgrade.If any objects in the list from before the upgrade are also in the list of invalid objects after the upgrade, you can be sure that this is not due to the upgrade process.

Oracle Software Installation( started )

1) Set the environment variables below by editing the files .dbenv_.sh and .dbenv_.csh in the home directory of ora.
(Do not make the changes to the environment permanent as long as the old database is still running)

a). Make sure the following environment variables are not set:
n TWO_TASK
n ORA_NLS
n ORA_NLS32
n ORA_NLS33

b). Set the following environment variables:
DISPLAY :0.0 (It is the host on which the OUI will be displayed.)
ORACLE_BASE /oracle
ORACLE_SID
ORACLE_HOME /oracle//102_64
NLS_LANG Set this to the output of the script CHECKS.SQL (/oracle/stage/102_64/database/Disk1/SAP . The database must be open before you execute the script CHECKS.SQL. )
ORA_NLS10 $ORACLE_HOME/nls/data
SAPDATA_HOME /oracle/
SHLIB_PATH $ORACLE_HOME/lib:$SHLIB_PATH


c). Include $ORACLE_HOME/bin in your PATH or path variable, replacing the existing variable with the new one:
set path = ($ORACLE_HOME/bin $path)
Check if the temporary directory (usually /tmp) has at least 400 MB of free space.


2) BackUp the Oracle Inventory

3)Running the Oracle Universal Installer

Start the OUI with the user ora as follows:
cd /oracle/stage/102_64/database/Disk1/SAP
./RUNINSTALLER


4) On The first screen press Next



5)



6) After this press Next next and you will see this screen




7) Installing the Current Patch Set
Only have to install the latest (that is, the current) patch set.
SAP Note 871735.
51036965_4 Patch CD.
Now enter the following command to unzip and extract the installation files:
$ unzip *.zip
Stop all listeners and other processes running in the Oracle home directory, where you need to install the patch set.
cd patchset_directory/Disk1
./runInstaller

8) Specify the detail and continue with installation

Prerequisites for DB Upgrade

1. Copying and Adapting the SQL*Net Files
I. Log on as user ora.
II. If ora have environment variable TNS_ADMIN set, do the following:
a) Choose a new location for the new SQL*Net parameter files and set TNS_ADMIN to point to the new location .
b) Copy the SQL*Net parameter files from the old location to
c) Edit the new SQL*Net files by adapting all file paths for the new directory. Be sure to adapt the value of ORACLE_HOME in the listener.ora file.

III. If ora has not set the TNS_ADMIN environment variable, Oracle first searches in /etc, in
$ORACLE_HOME/network/admin for the SQL*Net parameter files. Choose which of the following applies to your installation:
n The SQL*Net parameter files are located in directory /etc:
a) Make a backup copy of the files.
b) Edit the new SQL*Net files by adapting all file paths for the new directory. Be sure to adapt the value of ORACLE_HOME in the listener.ora file.
n The SQL*Net parameter files are located in /network/admin:
a) Copy the SQL*Net parameter files from to .
b) Edit the new SQL*Net files by adapting all file paths for the new directory. Be sure to adapt the value of ORACLE_HOME in the listener.ora file.

IV. Since your database is still running in the old environment, do not start the listener with the new
listener.ora file at this point.

2) Shutting Down the SAP System and Oracle Listener Process
stopsap r3
lsnrctl stop
Database Upgrade( Started)

1) Checking the oratab Entry
oratab file( /etc )

Registering a program on the Gateway

RFC connection test in SM59 might give error similar to this

———————————————————————————————————

Logon Connection Error

Error Details Error when opening an RFC connection

Error Details ERROR: program not registered

Error Details LOCATION: SAP-Gateway on host / sapgw

Error Details DETAIL: TP not registered

Error Details COMPONENT: SAP-Gateway

Error Details COUNTER: 16793

Error Details MODULE: gwr3cpic.c

Error Details LINE: 1694

Error Details RETURN CODE: 679

Error Details SUBRC: 0

Error Details RELEASE: 700

Error Details TIME: Mon APR 17 13:08:02 2009

Error Details VERSION: 2

———————————————————————————————————

The program in the above error should be registered in the gateway for this connection test to complete successfully. The server program rfcexec is responsible for its registration on the gateway.

To register the program login into the OS level as sudo su - adm and execute the following command.

rfcexec –g -a -x

rfcexec is the server program name, the can be obtained from SM59, it is case sensitive and should match with the entry in SM59. The and can be obtained from the transaction SMGW. When this command is executed it goes to a hanging loop.

The connection will fail once this command is terminated or the user executing this command logs off

To avoid this, instead of using the above mentioned command an entry should be made in the file saprfc.ini

To do this, execute the following command

sudo su - adm

rfcexec –D

is the RFC destination name in SM59

So now we are done with registering the server program, but how do we check it is registered, once a server program is registered it is displayed in the Logged on clients in SMGW.

In transaction SMGW choose GOTO-> Logged on clients. There should be an entry for the server program in the screen that is displayed with system type Registered_TP (which indicates that the program is registered)

There can be many reasons due to which we might get this error saying server program is not registered, once such instance which I faced was where in the TREX server, a new RFC destination was defined, the TREX server creates a new program id each time this RFC destination is defined. This program id was not changed in TCP/IP connection is SM59 which was the reason why the destination was failing

Problem in transport

Hi All,

Recently i have faced a issue with long running transports the reasons is some corrupted transports. So once you met this error you will not be able to even transport any other request.So here is the procedure through which you can resolve any issue related to STMS

1.) Ask everybody to leave the STMS transaction

2.) Ensure that there are no running transports (I mean currently
started) and kill all "tp" processes on all application server of BWP

3.) Copy to another location the content of /usr/sap/trans/tmp
afterwards truncate the content of /usr/sap/trans/tmp

4.) Delete the content of TRBAT and TRJOB tables on BWP if they
containing some entries

5.) Please take a screenshot of the Import Monitor of BWP and after that delete the entry within

6.) Start the failing imports again.



Enjoy Maadi...............
