Steps to create a self-signed certificate using OpenSSL

OpenSSL tool can be used to create a certificate / keystore.

You can download the latest version from the link below :

Before running OpenSSL make sure you set the following :

export OPENSSL_CONF=/tmp/package-root/usr/local/ssl/openssl.cnf

 If you want to install OpenSSL with a non-root user :

- $ ./config

- $ make

- $ make test

- $ make INSTALL_PREFIX=/tmp/package-root install

In this post we will see how to create a self-signed certificate/keystore using OpenSSL.

Steps to create a self-signed certificate and configure Custom Identity and Custom Trust with Weblogic Server using Keytool...

 What are self signed certificates and how to create them ?

A self-signed certificate is an identity certificate that is signed by the same entity whose identity it certifies.

 This term has nothing to do with the identity of the person or organization that actually performed the signing procedure. In technical terms a self-signed certificate is one signed with its own private key.
 Note :
 Identity keystores must contain a private key entry
 Trust store must contain all trusted key entries
 Below are few default values when using keytool command on JDK 1.6 :
 -alias "mykey"
    "DSA" (when using -genkeypair)
    "DES" (when using -genseckey)
    1024 (when using -genkeypair)
    56 (when using -genseckey and -keyalg is "DES")
    168 (when using -genseckey and -keyalg is "DESede")
-validity 90

Note :

-genkey is used in the example here. This was an old name used in previous releases. This old name is still supported in this release and will be supported in future releases, but for clarify the new name, -genkeypair, is preferred going forward.

Changes in keytool in Java 1.6 :

keytool no longer displays password input when entered by users. Since password input can no longer be viewed when entered, users will be prompted to re-enter passwords any time a password is being set or changed (for example, when setting the initial keystore password, or when changing a key password).

Some commands have simply been renamed, and other commands deemed obsolete are no longer listed in this document. All previous commands (both renamed and obsolete) are still supported in this release and will continue to be supported in future releases. The following summarizes all of the changes made to the keytool command interface:

Renamed commands:

-export, renamed to -exportcert
-genkey, renamed to -genkeypair
-import, renamed to -importcert
Commands deemed obsolete and no longer documented:

Steps to DeInstall Oracle Weblogic Server

How to DeInstall Oracle Weblogic Server ? 

- Oracle Weblogic Server 12.1.2 can be Deinstalled in two ways :

* GUI mode

* Silent Mode 

- For GUI mode go to " ORACLE_HOME\oui\bin " directory and run deinstall script.

- For Silent mode use the following command :

Go to " ORACLE_HOME\oui\bin " directory

./ -silent -response <deinstaller_response_file> 

- The deinstaller does not remove the JDK or any user-created data such as WebLogic domains or custom application data. Only the components that were installed by the installation program are removed by the deinstaller. 

- Make sure you have stopped all the servers / processes running before starting the DeInstaller.

In this post we will see how to DeInstall Oracle Weblogic Server

Steps to create a new domain on Weblogic Server

Weblogic Server Domain Configuration Wizard - Points to remember :

- Adding " " in Unix/Linux decreases the amount of time it takes for the Configuration Wizard to create or update a domain.

- Quick Start Configuration Wizard can be used only to configure the various sample domains, such as MedRec and the Examples Server, in your WebLogic Server installation.

- You can start Quick Start Configuration Wizard in two ways :

1. Select the Automatically Launch Quick Start Configuration Wizard option on the Installation Complete screen of the WebLogic Server installer.

2. Run the config.cmd / script located in ORACLE_HOME/oracle_common/common/bin as follows : " config.cmd -target=config-oneclick " in windows and " -target=config-oneclick " in Linux.

- Prior to manually running the Configuration Wizard in Quick Start mode, you must set the CONFIG_JVM_ARGS environment variable to specify the full path and JAR file name for each template that you want to use for the domain.

- To set CONFIG_JVM_ARGS on a Windows system:

set CONFIG_JVM_ARGS="-DuserTemplates=C:/Oracle/Middleware/wlserver/common/


export CONFIG_JVM_ARGS="-DuserTemplates=/Oracle/Middleware/wlserver/common/

- Domain can be created using GUI mode or using WLST.

- There is silent mode installation only for WLS 12.1.2 installation and not for WLS 12.1.2 domain creation.

- Nodemanager can now be configured in domain configuration wizard.

In this post we will see how to create a new Weblogic Server domain using DomainConfigurationWizard.
