How To Import LTPA Keys In WebSphere Application Server

IBM WebSphere Application Server ,
How To Import LTPA Keys In WebSphere Application Server

In this tutorial, we will find out how to import LTPA keys in the WebSphere Application Server. Lightweight third-party authentication (LTPA) is an IBM protocol that provides cookie-based or binary security token-based solutions to support single sign-on (SSO) environments. IBM WebSphere and other products use LTPA to allow single sign-on. When LTPA is enabled, you can log in to a WebSphere Server, and when you access other WebSphere servers, it will not ask you to enter credentials. You can log in to Domino first, and then when you access other WebSphere or Domino servers participating in SSO, it will not prompt you to log in.

Steps To Import LTPA Keys:

  1. Browse to the WebSphere Application Server(WAS) console (IBM console) and log in together with your user name and password.
  2. In the middle left of the screen, click on Security. After that, click on Global Security and then click on the LTPA radio button link.
  3. In the cross-cell single sign-on section, type password within the respective fields that you already entered while exporting keys from the first/primary server.

    import-ltpa-key
  4. Enter the key file name in the field and click on Import keys.
  5. Click on Apply and then click on OK.
  6. Save the configurations, sync node agents, and Restart WAS so that changes will take effect.

After reading this post you will easily import LTPA keys in WebSphere application server. Please do write in comment section in case of any queries or criticism.

How To Export LTPA Keys From WebSphere Application Server

IBM WebSphere Application Server ,
How To Export LTPA Keys From WebSphere Application Server

In this tutorial, we will learn and figure out how to export LTPA keys from WebSphere application server. The LTPA keys are used to help single sign-on (SSO) in WebSphere Application Server (WAS) over multiple WAS domains or cells, you just have to share the LTPA keys and the password across domains.

A common set of server encryption keys will be created and exported to enable single sign-on on all servers running the application. The visitors who are accessing the website for the first time will have to log in with a user ID and password. This information will be checked against the user registry (such as LDAP). The server will use the LTPA service to create a security credential token and write the cookie back to the browser (non-persistent). When the user later visits another LTPA server in the same domain, the information in the shared cookie will be reused to establish the user's security context with LTPA. Therefore, there is no need for a second login prompt.

Steps To Export LTPA Keys:

  1. Open a browser and log in to the WebSphere Application Server (WAS) console, also known as WAS console (Integrated Solutions Console).
  2. First, look at the middle left of the screen and click the Security tab. After that, click on Global Security and then click on the LTPA radio button link.
  3. In the cross-cell single sign-on section, you can enter the password of your choice in the password and confirm the password field.
    export-ltpa-key
  4. Then Enter the key file name in the field and click on Export keys.
  5. Click on OK.

In this article, I have explained how to export LTPA keys from WebSphere application server, and I hope that you will be able to do it after reading this article. In my next article, I will write about how to import LTPA keys in websphere application server. In case of any queries or criticism please do write us in the comment section.

Clear Cache In WebSphere Application Server Version 8.5

IBM WebSphere Application Server ,
Clear Cache In WebSphere Application Server Version 8.5

Yesterday, I required a clean WebSphere Application Server Cache because one among my colleagues was working on the IBM UNICA application, and she or he made some changes that require a WAS restart and clean WebSphere Application Server cache also. So, in this tutorial, we'll see the way to clear the WebSphere Application Server (WAS) Cache.

Why We Need Clean WebSphere Cache?

There are multiple reasons for which we sometimes need to clean the WebSphere cache.

  1. After the upgrade, the class cache may still retain the classes of the previous version.
  2. The cache may also be corrupted.

Types of Cache in WebSphere Application Server:

There are two types of cache in the WebSphere Application Server.

  1. JVM's cache
  2. OSGi cache

Clear JVM class Cache:

Note: - Remember, I have installed the UNICA application on Windows OS so, sharing the steps I performed on the Windows Operating System. But if you are running Unix or Linux , run the script with .sh instead of .bat

  1. Go to the command line by hitting window key + R from your computer and then type cmd. i.e., press window key + R →then type "cmd" from the keyboard → , and finally press Enter key.
  2. Go to the bin directory of the application server profile. In my case, it was E:/Unica/IBMWAS/WebSphere/AppServer/profiles/AppSrv01/bin
  3. Type clearClassCache.bat and press the Enter key. Once this command finishes, it will take you back to the command prompt.

Clear OSGi class Cache:

  1. Type osgiCfgInit.bat and press the Enter key. Once this command finishes, you will see two lines stating that the OSGI profile and WebSphere server cache are clear successfully.

    clean-websphere-cache
  2. If you are running WebSphere as a service, the clearClassCache command may not completely clear the javasharedresources folder. In this case, you need to perform another step.
  3. You need to go to your user's folder and then the AppData folder. By default, the Application Data folder is hidden. Press Window Key + R then Type CMD → then Type %appdata% → and at last Press Enter key.
  4. Then, go to the Local folder and take the backup of the javasharedresources folder.
  5. Remove/Delete all files within this folder. Everything is fine now.

Points to Remember:

  1. Please do not clean the cache when anyone of the JVM is running and cache is in use. You should stop the JVM server before clearing the cache.
  2. You must log in as the user who started WebSphere Application Server.

In the next article, I will explain how we can export LTPA keys from WebSphere Application Server. If you have question, queries or remarks related to this post please do write us in the comment section.
