Oracle client for 11g database

Look in to SAP Note 1431794 - Oracle 11.2.0: Instant Client, before working with
oracle client

Oracle instant clients version(s) 10.2.0.4.0 V3, 10.2.0.4.0 V4, 10.2.0.4 V5 and above are
currently supported for SAP environments with Oracle Database Release 11.2.0.1 and
11.2.0.2.

Oracle 11.2 Instant Client is not certified for use in an SAP environment. Currently the
Oracle 11.2 Client certification is planned for end of February 2011.
51039412 ORACLE Client V5 10.2.0.4

BRTools for 11g database
BR*Tools 7.20 patch 12
DBATL720O10_12-20005274.SAR DBATOOLS Package for Oracle 10g and 11g

BRTools 7.20 is specially designed for full support to oracle 11g
Look into sap notes: 1428529, 1430669

Preparation Steps (Database Should be Up and Running)
1. Login as oraSID user
2. Check permissions for /oracle filesystem. This users should have Read,Write and Delete
permissions to this folder and all sub-folders
a. Test steps
b. Touch /oracle/write_file
c. rm /oracle/write_file
3. Create /oracle/stage/112_64 directory and provide 777 permissions to this directory.
4. Extract the Oracle software
a. cd /oracle/stage/112_64
b. Move oracle media to this location and extract *.SAR files
SAPCAR –xvf OR111264.SAR
c. This creates folder called database and copies all the content.
/oracle/stage/112_64/database

Page | 4

ORACLE 11g Upgrade

5. Check the oraInventory directory
a. Back oracle inventory, if files exists
There will not be a file at this point in time

6. Create new oracle home directory in /oracle/SID
a. mkdir /oracle/SID/112_64
Provide permissions 755
Ownership orasid:dba

7. Prerequisites
Checking prerequisites for the OUI:
a. cd /oracle/stage/112_64/database
./runInstaller –executeSysPrereqs

Checking operating system requirements (release, patches, kernel parameters):
a. cd /oracle/stage/112_64/database
./runInstaller –executePrereqs

8. setting env variables
1. Make sure ORA_NLS10 is not set
2. Set env ORACLE_HOME = /oracle/SID/112_64
3. Set env ORACLE_HOME_SRC = /oracle/SID/102_64
4. Verify ORACLE_BASE, ORACLE_SID, SAPDATA_HOME
5. Set $ORACLE_HOME/lib:$LD_LIBRARY_PATH
6. Set
PATH=/oracle/SID/112_64/bin:/usr/java14_64/bin:.:/home/sidadm:/usr/sap/SID/SYS/e
xe/run:/usr/bin:/etc:/usr/sbin:/usr/ucb:/usr/bin/X11:/sbin:/usr/java14/jre/bin:/usr/java14/
bin:/usr/local/bin

9. Oracle 11g binaries installation:
cd /oracle/stage/112_64/database/SAP
./RUNINSTALLER

At the end of installation it will pop a window asking to root.sh script
located in /oracle/SID/112_64/root.sh

Log on with root user
Go to directory /oracle/SID/112_64
Run ./root.sh

ORACLE 11g Upgrade

Now come back to pop window and click on ok.
Oracle 11g binaries installation completed.

10. Copying Pre and post upgrade scripts to /oracle/<DBSID>/112_64
skzddb35:oracab 5%cd /oracle/<DBSID>/112_64
skzddb35:oracab 6%ls
sap
skzddb35:oracab 7%mv sap sap_orig

Copy scripts to /oracle/<DBSID>/112_64

skzddb35:oracab 9% Unzip p9584028_112020_Generic.zip
skzddb35:oracab 10% ls
p9584028_112020_Generic
skzddb35:oracab 11% cd p9584028_112020_Generic/9584028
skzddb35:oracab 12% ls
etc files README.txt
skzddb35:oracab 12% cd files
skzddb35:oracab 13%ls
sap
skzddb35:oracab 13%cp –rpf sap /oracle/CAB/112_64/
Here new scripts are replaced with old scripts

11. Oracle 11g patch set:
Currently 11.2.0.2 is the latest and is available as direct installation, as of now no patch set is
required. Look in market place for new oracle patch set, if available.

12. Installing the Required SAP Bundle Patch:
Currently SAP Bundle Patch 11.2.0.2.1 is available
SAP_112021_201102_SOLX8664.zip or SAP_112021_201102_SOL64.zip, implement same using latest MOPatch

13. Create links with shared library, to make BRTools 7.20 work with 11g
cd oracle/SID/112_64/lib
Ln –s libnnz11.so libnnz10.so

14. Copy SQL*Net Files
Copy listener.ora, sqlnet.ora, and tnsnames.ora from /oracle/SID/102_64/network/admin
Directory to /oracle/SID/112_64/network/admin

Add the following entry to the file listener.ora:
ADR_BASE_LISTENER = /oracle/DBSID/saptrace

ORACLE 11g Upgrade

15. Update oracle client
Create 10x_64 directory, permissions 755, ownership oracle:dba
Uncar OCL10264.SAR and move the contents to oracle/client/10x_64 directory

51039412 ORACLE Client V5 10.2.0.4

15. Updating env profiles
Log on sidadm user
Make changes to .sapenv_hostname.csh
setenv LD_LIBRARY_PATH /usr/sap/SID/SYS/exe/run:/oracle/client/10x_64/instantclient

Make changes to .dbenv_hostname.csh
setenv ORACLE_HOME /oracle/CAB/112_64
setenv ORA_NLS10 /oracle/CAB/112_64/nls/data

16. Before starting oracle 10g upgrade (Database upgrade)
Verify and confirm below environment variables points to 11g directories.
Note: env will be different for both <SIDADM> and <ORASID> users.
a. ORACLE_HOME = /ORACLE/<DBSID>/112_64
b. Path
c. ORA_NLS10
d. LD_LIBRARY_PATH

e. Copy listener.ora, tnsnames.ora, sqlnet.ora from /oracle/CAB/102_64/network/admin to
/oracle/CAB/112_64/network/admin
And make changes in those files accordingly to 10g directories.

f. Verify /var/opt/oracle/oratab file.
There should be a entry as SID:/oracle/SID/102_64:N, it should be with 102_64 directory.
Never make changes to oratab file starting actual database upgrade..

17. Running the Pre-Database Upgrade Scripts
cd /oracle/<DBSID>/112_64/sap/ora_upgrade/pre_upgrade

SQL> conn /as sysdba
Connected.
SQL> spool /oracle/stage/log/pre_upgrade_status.log
SQL> @/oracle/<DBSID>/112_64/sap/ora_upgrade/pre_upgrade/ pre_upgrade_status.sql
SQL> spool off

./dbua.sap.sh –q In query mode certain parameter files (init<DBSID>.sap,
listener.ora,
etc.) are copied from the source Oracle Home to the
target Oracle
Home.

Database structure is updated.

SQL> select version from v$instance;
VERSION
-----------------
11.2.0.2.0

SQL> select comp_id, version, status from dba_registry;
COMP_ID VERSION STATUS
------------------------------ ------------------------------ -----------
CATALOG 11.2.0.2.0 VALID
CATPROC 11.2.0.2.0 VALID

19. Checking the Upgraded Database

20. Post upgrade steps
1. SQL> alter system set compatible=’11.2.0’ scope = spfile;
System altered.

Restart database..

Extract DBATL720O10_12-20005274.SAR
and place in /sapmnt/SID/exe directory
Run ./saproot.sh SID

Check brtools owner and permissions in directory /sapmnt/SID/exe

BRTools upgraded.

4. Gather Oracle optimizer statistics by executing the following commands as the
ora<dbsid> user:
brconnect -u / -c -f stats -t system_stats
brconnect -u / -c -f stats -t oradict_stats

5. Update the Oracle database statistics with BRCONNECT as follows:
brconnect -c -u / -f stats -t all –f collect -p 4

6. Now try logging with user = schema owner (SAPR3) with default password SAP.

If log on was not successful then change password using brtools or brconnect
command.
Brconnect –u system/<syst_pwd> -f chpass –o sap<sid> -p <new_sap_pwd>
Check and verify logon is successful

SQL> conn
Enter user-name: sapr3
Enter password:
7. Check if all links are loading.
skzddb35:oracab 54% cd /sapmnt/CAB/exe
skzddb35:oracab 55% ldd dboraslib.so
8. Check sap connectivity
skzddb35:cabadm 54% R3trans –d
This is R3trans version 6.14 (release 700 - 12.01.10 - 10:02:00).
R3trans finished (0000).
9. Update oracle client on app servers
10. Look for short dumps..
