I posted two blogs on the top 10 best practices of using the vSphere SDK (part 1, part 2) two days ago. Here is a list of several common mistakes developers make during their development. It’s based on the stats from our SDK support team. Read more... (111 words, estimated 27 secs reading time)
- Defining wrong interval information in PerfQuerySpec
- Using same unit number for each device attached to a controller
- Mistakes in defining the TraversalSpec
- Using case sensitive DNS names or IP address

#6 Consider Views in Your GUI Application
Most developers don’t know much about the View and related managed objects. The reason for that is that they were mainly designed for VI/vSphere Client in the first place. But nothing stops you from using it to your advantages.
As you can imagine, you can use the View and its subtypes InventoryView, ListView, and ContainerView to monitor changes on the server side. It provides an efficient way to monitor for changes with only these visible in your GUI and nothing more. You can use ViewManager to create views according to your specific needs. Read more...

VMware vSphere (as known as VI in earlier versions) SDK includes a comprehensive set of APIs managing the vSphere CloudOS. It can be used to build different types of applications: standalone GUI applications, vSphere Client plug-in, utility tools, Web applications, server applications. It is becoming increasingly important as more and more enterprises become 100% virtualized with vSphere. Read more... (788 words, estimated 3:09 mins reading time)
Besides the talks on VMware APIs, two self paced labs are there for you to try out the vSphere SDK and PowerShell at PEX. More details are quoted in later part.
As a bonus, you will get a chance to learn VI Java API in the SDK lab. Thanks to VMware TAM Alton Yu for making this happen! I will be there when I am not presenting my talk “Architecting Your Applications for VMware Cloud”, or helping on the BOF, genius bar, etc. Read more... (325 words, estimated 1:18 mins reading time)
Search has been a hot topic since Google successfully monetized it with advertising business model. Besides general Web content search like Google does, there are many other types of searches needed for other Internet companies.
LinkedIn.com, with which most of us have created profiles, offers search capabilities based criteria like keywords, names, location, industry, companies currently with and before, school, etc. Because what Linkedin.com has is well structured data, you and I expect it to do a better job than Web searches. In fact, it does. Read more... (629 words, estimated 2:31 mins reading time)
After we released VI Java 2.0 GA for about half year, it’s about time to plan for the next release. My current plan is to have a synchronized release with next major release of vSphere. Therefore the must-have feature is to support next vSphere.
On top of that, here are several things we most likely do as well: Read more... (408 words, estimated 1:38 mins reading time)
Last week VMware released a news “VMware Expands VMware vCloud Developer Ecosystem With Open-Source Java and Python SDKs for VMware vCloud API”. It says,
VMware has also made a number of open-source contributions to the Cloud Tools project, which powers the SpringSource Cloud Foundry service, enabling Java developers to deploy, test, and manage applications for VMware environments via VMware vSphere(TM) and the VMware vCloud API.

Today I read a posting at VMware community forum about the weird code required by C# Web Service. If the following line is missing, then the vSphere API call to get properties doesn’t work:
VimApi.VimService.PropertySpec.allSpecified = True
But the problem is that there isn’t any property defined as allSpecified in the object PropertySpec according to vSphere API Reference.
So, where does the allSpecified come from? and why is it needed? Read more... (525 words, estimated 2:06 mins reading time)
Our business team invited me to a phone call with one of our strategic partners days ago. They had a scalability issue with their server application. It turned out to be related to session management. I think they are not the only one who got into this type of problems, and most likely not the last one. So I decide to share it and hopefully you can avoid similar problems in your projects. Read more... (584 words, estimated 2:20 mins reading time)
