Session management is a very important part of vSphere management, especially when scalability is involved. I’ve blogged about this in my previous posts (1, 2). If you haven’t read them yet, it’s high time to do so.
In this article, I am going to share with you a new finding while helping a development team. By default, an idle session is terminated by vSphere server after 30 minutes. The team found that it’s not totally true. They use several types of sessions for different purposes. Two of the sessions remain live even after the 30 minute default while others are gone.

It’s a known bug in VI Java API that it did not escape strings to be included within a XML tag. The potential risk, although very very rare, is that it can blow the de-serialization of a request on the server side. I did get one or two reports on failing on login, which turned out to be caused by special characters like < or > in passwords. As a quick fix, an escaping logic has been added to escape the special characters in passwords. Read more... (386 words, estimated 1:33 mins reading time)
In my previous articles, I mainly cover server virtualization and cloud computing. Client computing, although less enterprise focused, is also a very important part of whole story. In this article, I am going to share some thoughts on this topic, mostly about the future development of how users will use computers and what it takes to get there. I know it’s a big topic, but let’s give a try. Read more... (722 words, estimated 2:53 mins reading time)
After the vSphere Java API 5.0 beta was released, I got a very interesting bug that I think is worthwhile to share with the community. Note that I used the word “interesting.” It turned out to have no solution logically, but quite easy to work around and patch up. The workaround addresses only particular issue but does not prevent similar bugs from happening in the future.
Confused? Let’s take a quick look at the bug report: Read more... (618 words, estimated 2:28 mins reading time)
As a developer, I’m always interested in latest development of middleware platforms. Yesterday came a big news from VMware: the vFabric 5 Cloud Application Platform reached GA. For those who might not be familiar with vFabric, it is an integrated suite of middleware for deploying and managing applications.
Note that despite the version number, this is the first release of the vFabric platform. I guess the version 5 may be just for aligning with vSphere 5. Also, this is a suite of products that have been there for a while. Read more... (272 words, estimated 1:05 mins reading time)
Among all the new features vSphere API exposes, I think VIX integration is very important. All of sudden, the vSphere API gets a boost on manageability of guest OS, and you can do many more with single set of APIs. Read more... (533 words, estimated 2:08 mins reading time)
In his keynote at VMworld last week, VMware CTO Steve Herrod showed a very interesting project called AppBlast. According to this news release thereafter, “Project AppBlast will provide the universal delivery of any application, including Windows-based applications, to any device supporting HTML5, enabling instant remote access to applications without the heavy footprint of the underlying operating system.” Read more...

As reported by the open source VI Java API community, a bug came to my attention. It’s related to the Client REST API which is a powerful hack with vSphere MOB based on a little secret. Started in vSphere 4.1 update 1, things started to break if you want to call a method with the REST API while retrieving properties continues to work. Read more...
