Low Level Steps
1-Prerequisites
- You must go throw the README files
- You must use the OPatch utility version 12.2.0.1.43 or later to apply this patch.
2-Download Patches
3-Copy Patches to Servers
I have copied patches to /u01/software/ directory.
4-Check & Update OPATCH Utility
You must use the OPatch utility version 12.2.0.1.43 or later to apply this patch.
Check OPATCH version
Check Version
sudo su -
su - oracle
. oraenv
cd $ORACLE_HOME/OPatch
./opatch version
# Sample Output
[oracle@oraclelinux810-test OPatch]$ ./opatch version
OPatch Version: 12.2.0.1.44
OPatch succeeded.
[oracle@oraclelinux810-test OPatch]$Backup Current OPatch (Skip if you have the latest version of OPatch)
cd $ORACLE_HOME
mv OPatch OPatch_12.2.0.1.43Upgrade OPATCH (Skip if you have the latest version of OPatch)
cd /u01/software/
unzip /u01/software/p6880880_190000_Linux-x86-64 -d $ORACLE_HOME/Check Version
cd $ORACLE_HOME/OPatch
./opatch version5-Verify the Database Current Version
Using the below command verify the current version details and some other information related to the database.

Due to any type of error if patching got failed, then you must have a backup plan.
- Take Oracle Home Backup
- Take Central Inventory Backup
- Create Guaranteed Restore Point
Take Oracle Home Backup (if you have enough disk space)
How to Perform ORACLE_HOME Backup? (Doc ID 565017.1)
# Backup
# (Suggested but not mandatory) Shutdown databases, listeners, or any other processes related to the ORACLE_HOME which you are taking backup.
# Make sure there is enough free disk space before doing the backup.
cd /u01/app/oracle/product/<version>/
tar -pcvf /u01/backup/oracle_home_bkup_DDMMYYYY.tar <dbhomename>
# Restore
# (This step would be mandatory in the case of restore) Shutdown databases, listeners, or any other processes related to the ORACLE_HOME which you are restoring.
cd /u01/app/oracle/product/<version>/
mv <dbhomename> <dbhomename_DDMMYYYY>
tar -pxvf /u01/backup/oracle_home_bkup_DDMMYYYY.tarTake Central Inventory Backup
# Backup
# (Suggested but not mandatory) Shutdown databases, listeners, or any other processes related to the ORACLE_HOME which you are taking backup.
more /etc/oraInst.loc
cd /u01/app/
tar -pcvf /u01/backup/oraInventoryBackup_DDMMYYYY.tar oraInventory
# Restore
# (This step would be mandatory in the case of restore) Shutdown databases, listeners, or any other processes related to the ORACLE_HOME which you are restoring.
cd /u01/app/
mv oraInventory oraInventory_DDMMYYYY
tar -pxvf /u01/backup/oraInventoryBackup_DDMMYYYY.tarCreate Guaranteed Restore Point
# Create Guaranteed Restore Point
1. $> su – oracle
2. $> sqlplus / as sysdba;
3. Find out if ARCHIVELOG is enabled
SQL> select log_mode from v$database;
If step 3 shows that ARCHIVELOG is not enabled then continue else skip to step 8 below.
4. SQL> shutdown immediate;
5. SQL> startup mount;
6. SQL> alter database archivelog;
7. SQL> alter database open;
8. SQL> create restore point before_upgrade guarantee flashback database;
where CLEAN_DB is the name given to the guaranteed restore point.
9. Viewing the guaranteed restore point
SQL> select * from v$restore_point;
Verify the information about the newly created restore point. Also, note down the SCN# for
reference and we will refer to it as "reference SCN#"
# Flashback to the Guaranteed Restore Point
1. $> su – oracle
2. $> sqlplus / as sysdba;
3. SQL> select current_scn from v$database;
4. SQL> shutdown immediate;
5. SQL> startup mount;
6. SQL> select * from v$restore_point;
7. SQL> flashback database to restore point before_upgrade;
8. SQL> alter database open resetlogs;
9. SQL> select current_scn from v$database;
Compare the SCN# from step 9 above to the reference SCN#.
NOTE: The SCN# from step 9 above may not necessarily be the exact SCN# as the reference SCN# but it will be close enough.
# Drop Guaranteed Restore Point
drop restore point before_upgrade;7-Pre Patch Steps

Make sure 7 GB of disk space is free in your binary location otherwise the patch will be failed.

Now it’s time to run datapatch -verbose which updates the patch information at the database binary & dictionary level as well as binary files.
Run datapatch -verbose
Important Note: For each separate database running on the same shared Oracle home being patched, run the datapatch utility
. oraenv
cd $ORACLE_HOME/OPatch
./datapatch -sanity_checks (optional)
./datapatch -verboseExecute utlrp.sql
Once datapatch -verbose is completed then execute the utlrp script to validate the invalid objects.

Patch Deinstallation Instructions
Shut down all instances and listeners associated with the Oracle home that you are updating.
sudo su - su - oracle . oraenv lsnrctl stop LISTENER sqlplus / as sysdba shut immediate quit cd $ORACLE_HOME/OPatch opatch rollback -id 36912597 opatch rollback -id 36878697Rollback SQL Changes from the the Database
Datapatch is run to complete the post-deinstall SQL deployment for the patch being deinstalled.
Important Note: For each separate database running on the same shared Oracle home being patched, run the datapatch utility.
lsnrctl start LISTENER sqlplus / as sysdba startup quit cd $ORACLE_HOME/OPatch ./datapatch -sanity_checks (optional) ./datapatch -verbose
