Install and Deinstall Oracle Patches use Opatch command.

Opatch (Apply Oracle Patches )

Install and Deinstall Oracle Patches use Opatch command.
(After complete this demo you will able to Apply oracle Patches on Middleware home or Jdeveloper Home)

Download patches
1- Download your patch from Oracle Support .

· Go to search tab and write your patch number or search criteria.

· Download your patch .

2- Create a new folder in OS root to locate your patch , and unzip patch file into this folder

C:\OraclePatches

------------------------------------------------------------

Pre Installation

3- Set System environment variable ORACLE_HOME

- Weblogic set variable to your middleware directory (For Weblogic )

Oracle_Home = [MW_HOME]\ oracle_common

- Jdeveloper set variable to you Jdeveloper Home

Oracle_Home = [Jdeveloper_HOME]\jdeveloper

4- Stop All managed servers and Admin Server before apply patch. I prefer to backup your MW_HOME directory.

If you apply patch in Jdeveloper , please shutdown Integrated Weblogic and close Jdeveloper IDE.

5- Open cmd Command and set your current directory to directory where your patch is located .

cd C:\OraclePatches\21768703\oui

6- Use Opatch Apply command to apply current patch .

(may you will face a conflict when applying the patch ,because patch already applied before )

C:\OraclePatches\21768703\oui>opatch apply –Jdk [JDK path]

------------------------------------------------------------

Post Installation

7- For Jdeveloper: Open Jdeveloper and clean project and rebuild, then start Integrated Weblogic and run and test your application after patch and check problem is resolved .

8- For standalone Weblogic server : start Admin Server , then start node manager , then start Managed Server . and check your Problem is resolved .

------------------------------------------------------------

List Patches installed in your Oracle_Home

to list all patches installed in your Oeracle_Home

Open cmd command and write command

/> Opatch lsinventory

------------------------------------------------------------

Deinstall patch

1- Stop All managed servers and Admin Server before apply patch . If you apply patch in Jdeveloper , please shutdown Integrated Weblogic and close Jdeveloper IDE.

2- Open cmd Command and set your current directory to directory where your patch is located .

cd C:\OraclePatches\21768703\oui

3- Use Opatch rollback command to deinstall current patch .

C:\OraclePatches\21768703\oui>opatch rollback –Jdk [JDK path]

4- Clean you all files in tmp folder in OS User Directory

Jdeveloper :

[JDEV_USER_DIR]\DefaultDomain\servers\DefaultServer\tmp\*

Middleware:

[MW_HOME]/user_projects/domains/[DOMAIN_NAME]/servers/[SERVER NAME]/tmp/*

------------------------------------------------------------

Post DeInstallation

1- For Jdeveloper: Open Jdeveloper and clean project and rebuild, then start Integrated Weblogic and run and test your application after patch and check problem is resolved .

Weblogic does not start and throw an exception: java.lang.NumberFormatException

    <Critical> <WebLogicServer> <BEA-000386>

When i tried to start Weblogic Server , server did not work , and gave me an exception java.lang.NumberFormatException= null

 This problem may happen because i changed some server configurations when server running and made a corruption if file replicas.prop in the server .




Solution  : Remove this corrupted file , and let Weblogic auto generate this file again when server restart .


1- Open your server which  weblogic installed.

2- go to this path 

$<YourDomain>/servers/AdminServer/data/ldap/conf



3- rename this file replicas.prop to old-replicas.prop 


4- restart  Weblogic server .


5- Smile every thing is Okay now ....
