Patching Oracle 18c database in Windows

Download the database patch from Oracle support

Also, download the latest OPatch utility for Windows OS as shown below:

Picture1

Check your environment variables:

set PATH=%ORACLE_HOME%\perl\bin;%PATH%

set ORACLE_HOME=D:\Oracle18c_Windows\WINDOWS.X64_180000_db_home

set PERL5LIB=

Shutdown Oracle database services:

Stop Distributed Transaction Coordinator

net stop msdtc

Go to the directory where the patch is downloaded

cd D:\ORACLE_WINDOWS_PATCHING\29589622

D:\OPATCH_DOWNLOAD\OPatch\opatch apply

When you try to apply the patch the following  error will occur if the OPatch utility is NOT placed within the Oracle database home binary

Picture3

Error in Text: The Oracle Home D:\OPATCH is not OUI based home. Please give proper Oracle Home

after placing the OPatch utility under Oracle Home, apply the patch:

D:\Oracle18c_Windows\WINDOWS.X64_180000_db_home\OPatch\opatch apply

To resolve this error I will rollback this patch first:

D:\Oracle18c_Windows\WINDOWS.X64_180000_db_home\OPatch\opatch rollback -id 28267731

Picture5

And attempting to re-apply the patch will succeed

Startup the Oracle services again:

exit;

cd D:\Oracle18c_Windows\WINDOWS.X64_180000_db_home\OPatch

Applying RU (Release Update) to Oracle 18c

Since Oracle 12cR2 RU(Release Update) and RUR (Release Update Revision) was introduced by Oracle for patching every quarter.

The following is the guide in how to apply RU to Oracle 18c release, as you might know Oracle introduced 18c on-premise with 18.3 release….here i am applying January 2019 Oracle Security Patch release which is 18.5.

its worth pointing out that you might face patching issues…..check the below helpful references i blogged about it before:

https://geodatamaster.com/2018/07/19/oracle-psu-july-2018-error-ora-20001-latest-xml-inventory-is-not-loaded-into-table/

https://geodatamaster.com/2018/11/04/oracle-ojvm-psu-error/

download the latest RU patch and place it in a directory accessible by your database server:

cd /oracle-app/linux/18c_RU/18.5_DB/28822489

/$ORACLE_HOME/OPatch/opatch apply

opatch2

opatch222

sqlplus / as sysdba

SQL> STARTUP

exit

cd $ORACLE_HOME/OPatch

./datapatch -verbose

datapatch1

*** Post-Patch verification:

sqlplus / as sysdba
SQL> @?/rdbms/admin/utlrp.sql
//check your database components

SQL> select COMP_NAME,STATUS from dba_registry;
// query to list applied patches on the database instance:

SQL > select * from dba_registry_sqlpatch;

dba_registry_sqlpatch1

so the database has been successfully patched with full release number 18.5.0.0190115

if your database has “java” component, you need to download the java patch (OJVM) and repeat the above steps….except that you will startup the database in upgrade mode before running the data-patch.

I hope this is helpful……have a nice day.
