If you look at the WebSphere Portal 6.1 Infocenter for Adding new Ldap attributes to your Websphere Portal 6.1 configuration it basically gives you several steps and repeat steps to follow to get your new ldap attributes added like running the task which would install the ear file (./ConfigEngine.sh wp-la-install-ear -DWasPassword=password) and running ./ConfigEngine.sh wp-add-property

Back in 2009 I used to write a lot of blog articles until Google came and screwed up by blog index made my blog search traffic to drop by 75% and i probably lost my motivation (why write when no one is reading it ? ). Now it seems they might have fixed something and my blog search traffic has been back to normal levels, my be i will get my motivation back :).If you look at the above stats ,

Although lot people are finding various ways to speed up their application servers to improve performance, there are also benefits to slow down your server process especially when testing it to find problems that you won't see in normal scenarios. As you might have seen in your experience that 90% of the time things work well in a normal scenario when there the load on the server is normal, db

Since IBM and Amazon announced the avalability of WebSphere Portal Server and Lotus Web Content Management Standard Edition on the Amazon EC2 Web Service, I used to wonder whether there are any real-world customers using it. But now it seems from the news, that an investment firm Quintana Capital Group converted its Web site and IBM WebSphere-powered portal to Amazon's EC2. Here is the URL http:/

We recently had an issue where the websphere Java process got hung and freezes in 4 servers almost at the same time, where 3 server nodes are part of a cluster and the other one is a standalone. Restarting of websphere AppServer fixed the issue. This issue was still puzzling as to why all the servers got hung at the same time and even the one that is not part of the cluster got hung as well. We

As many of us generally know, Java is popular for it's cross-platform portability "Write once, run anywhere", but i wanted to give it a test and see if it's truly one. I tried to run WebSphere 7 Application Server itself using Sun JRE 1.6.0 instead of IBM J9 VM which is bundled with AppServer and see if it works with cross vendor JVM on the same platform. I had to make couple of changes, the

Nowadays more and more graphical tools like jconsole , jvisualvm are shipped with java and several other tools like tda-Thread Dump Analyzer , IBM HeapAnalyzer , etc are available for download to analyze and debug problems, hence it seems like you need to have some kind of graphical terminal like Xserver or VNC to manage your environment. Since most of the production environments are UNIX/Linux

I found this WebSphere Education channel on youtube.com, thought i should publish it to my blog.

I am sure many of the Application or System administrators might have encoutered the issue of SSL certificates getting expired in the middle of the day causing application outages. The part of the reason is that the application server environments are getting complex day by day in terms of number of systems it's interacting over SSL like LDAP, WebServices, WebSever plugin, Siebel and even

As many of you might now already that LRUMap is not synchronized and is not thread-safe. If you wish to use this map from multiple threads concurrently, you must use appropriate synchronization. The simplest approach is to wrap this map using Collections.synchronizedMap(Map). But even after using this method lrumap=Collections.synchronizedMap(new LRUMap(10)) , particularly when serializing the

During production installation of WebSphere, particularly where multiple node cluster is involved you will be overwhelmed with how many firewall changes need to be made across different vlans and open ports to make sure all the nodes, dmgr, websevers, databases, & ldap can communicate with each others without problems. Also at the same time make sure you only open the ports that are needed

You might think it's something simple like typing java -version to find , yes it is for most Java versions, except for Sun JDK 32-bit version doesn't explicitly say which is causing confusion to many users which kind of prompted me to write this article.If you run java -version in Sun HotSpot 1.6 VM , you will see the below output showing nothing about the bit on the 32-bit JVM where as in 64-bit

You might think that on a 32-bit OS, a process should be able to address address 2^32 = 4Gb of address space, however in practice some of the address space is used by the OS kernel and so is not available to the process. So there are limitations to how much a process can address and it can vary depending on the platform and the versions of JDK. There are programs like IBM Heap Analyzer requires

With the default settings of the Java 1.6 HotSpot VM running in a -server mode don't expect your java code to be compiled before 10000 invocations of same code block or the method. This may not be suitable for servers where your server load is less and might take a long time to reach 10000 invocations or where you have an environment with multiple cells and the cell gets flipped every day before

If you have used websphere datasources you might have seen a jdbc connection pool setting called Aged Timeout specifies the interval in seconds before a physical connection is discarded irrespective of whether the connection was idle or used before. This property is usually set to a specified interval to maintain the freshness of the connection between the database and also to avoid any firewall
