ORACLE 12C Pre Upgrade steps
1. mkdir -p /oracle/stage/12102
chmod 755 /oracle/stage/12102
2. To upgrade a single instance database on the file system, you only need to extract the database software that is contained in the first 2 SAR files OR112164.SAR and OR212164.SAR
Move these to location stage
2.1 Backing Up the Central Oracle Inventory
oracle> more /etc/oraInst.loc
inventory_loc=/opt/oracle/oraInventory
inst_group=dba
Install database
Call RUNISTALLER and follow the instructions as per the screens you are getting
Check SAP Note 1914631 to find a cross-reference to the current SAP Note with the list of required patches to be installed

Executing Pre-Installation Instructions
Set environment variable s:
DISPLAY
OHRDBMS = /oracle/SID/121
IHRDBMS= /oracle/SID/12102
Unless otherwise stated, you can execute the following pre-installation instructions before you shut down the
database applications or the database instances.
SAP12102P_1503-20012300.ZIP
(this SBP) to the database host.Extract OPatch and MOPatch and install them in the Oracle Home:
unzip -qd $IHRDBMS/sapbundle SAP12102P_1503-20012300.ZIP 'SBP_121022_201503/OPatch/*'
mv $IHRDBMS/OPatch $IHRDBMS/OPatch-pre-SBP_121022_201503
mv $IHRDBMS/sapbundle/SBP_121022_201503/OPatch $IHRDBMS/OPatch
unzip -qd $IHRDBMS/sapbundle SAP12102P_1503-20012300.ZIP 'SBP_121022_201503/MOPatch/*'
test -d $IHRDBMS/MOPatch && mv $IHRDBMS/MOPatch $IHRDBMS/MOPatch-pre-SBP_121022_201503
mv $IHRDBMS/sapbundle/SBP_121022_201503/MOPatch $IHRDBMS/MOPatch
mv $IHRDBMS/sapbundle/SBP_121022_201503/MOPatch $IHRDBMS/MOPatch
Installing the SAP Bundle Patch
Follow the steps below.
fuser
OS command to check$SBPFUSER $IHRDBMS/bin/oracle
If that command reports running processes, these are stale SQL*Plus sessions, which you can safely terminate with the kill
command.
Install the SAP Bundle Patch as follows:
env ORACLE_HOME=$IHRDBMS $IHRDBMS/MOPatch/mopatch.sh -v -s SAP12102P_1503-20012300.ZIP
Start up the database instances, the listener, and other processes running from the Oracle Home
SQL> Startup
Listener
oracle> lsnrctl start LISTENER
Check that the environment variables ORACLE_HOME and ORACLE_SID are set. For user oracle, you can set the environment with oraenv (sh
shell) or coraenv (csh shell). Make sure that ORACLE_HOMEis set to the value of the current Oracle home, <old_Oracle_home>.
Change to the correct directory by entering the relevant command:
cd /oracle/<DBSID>/12102/sap/ora_upgrade/pre_upgrade
Execute the following commands to perform pre-upgrade tasks, which can improve the performance of the upgrade process:
sqlplus / as sysdba
SQL>@pre_upgrade_tasks.sql
Execute the following commands to check the pre-upgrade status of your database:
sqlplus / as sysdba
SQL>@pre_upgrade_checks.sql
Check the results of pre_upgrade_checks.sql and take actions as suggested in the log.
Below were the actions suggested by run of : pre_upgrade_checks.sql
************************************************************
************************************************************
====>> PRE-UPGRADE RESULTS for SID <<====
ACTIONS REQUIRED:
1. Review results of the pre-upgrade checks:
/oracle/cfgtoollogs/SID/preupgrade/preupgrade.log
2. Execute in the SOURCE environment BEFORE upgrade:
/oracle/cfgtoollogs/SID/preupgrade/preupgrade_fixups.sql
3.Execute in the NEW environment AFTER upgrade:
/oracle/cfgtoollogs/SID/preupgrade/postupgrade_fixups.sql
************************************************************
***************************************************************************
Pre-Upgrade Checks in SID Completed.
*******************************************************************
Pre ugrade tasks
Execute in the SOURCE environment BEFORE upgrade:
/oracle/cfgtoollogs/SID/preupgrade/preupgrade_fixups.sql
Now you are done with preupgrade tasks on source Database and you can proceed to upgrade the Database to ORACLE12C
