How to change MAC Address of existing Virtual Machines


I was having problem with my ethernet MAC in one of my VMs. I just did remember that I did not write post about this, so I am writing this now.

You will be simply failed if you have tried below things..,

1. Removing that ethernet from VM and adding new one

2. Generate a new MAC from the ethernet settings.


So what is the work around ?

lets start…,

Step 1.  Go to your VM working directory to the one you are facing issues. from Virtual Machine settings.


Step 2.  Edit the .vmx file by any text editor and find the below three entries below and remove completely from that file.

In my case these are below entries for you it will be in enthernet[n].generatedAddress= “your current MAC”

ethernet0.generatedAddress = "00:0c:29:2b:5b:8e"

ethernet0.generatedAddressOffset = "0"

ethernet0.addressType = "generated"



Step 3.  Add a new static MAC address line to the configuration file with help of the following entries:

ethernetN.address = "00:50:56:XX:YY:ZZ"
ethernetN.addressType = “static”

XX should be  hexadecimal number between 00h and 3Fh,

YY  and ZZ should be  valid hexadecimal numbers between 00h and FFh.

How the JTA Transaction Manager helps to GemFire


JTA provides direct coordination between the GemFire cache and another transactional resource,

such as a database. Using JTA, your application controls all transactions in the same standard way, whether the transactions act on the GemFire cache, a JDBC resource, or both together.

By the time a JTA global transaction is done, the GemFire transaction and the database transaction are both complete.

imageContributed by Gemstone.

Using GemFire with JTA transactions requires these general steps.

During configuration:
1. Configure the JDBC data sources in the cache.xml file.
2. Include the jar file for any data sources in your CLASSPATH.

At run-time:
3. Initialize the GemFire cache.
4. Get the JNDI context and look up the data sources.
5. Start a JTA transaction.
6. Execute operations in the cache and database as usual.
7. Commit the transaction.

The transactional view exists until the transaction completes. If the commit fails or the transaction is rolled
back, the changes are dropped. If the commit succeeds, the changes recorded in the transactional view are
merged into the cache. At any given time, the cache reflects the cumulative effect of all operations on the
cache, including committed transactions and non-transactional operations.

JTA Transaction Limitations:

• Only one JDBC database instance per transaction is allowed, although you can have multiple connections
to that database.
• Multiple threads cannot participate in a transaction.
• Transaction recovery after a crash is not supported.
In addition, JTA transactions are subject to the limitations of GemFire cache transactions, which is discussed
in the previous section. When a global transaction needs to access the GemFire cache, JTA silently
starts a GemFire cache transaction.

JTA Sync Up :

JTA syncs up multiple transactions under one umbrella by enabling transactional resources to enlist with a
global transaction. The GemFire cache can register as a JTA resource through JTA synchronizations. This
allows the JTA transaction manager to call methods like commit and rollback on the GemFire resource and
manage the GemFire transactions. You can bind in JDBC resources so you can look them up in the JNDI
context. When bound in, XAPooledDataSource resources will automatically enlist if called within the context
of a transaction.

Example :

Using GemFire JTA Transaction Manager

The external data sources used in this transaction are configured in cache.xml.

Region r = ...; // the gemfire regionDataSource 
ds = ...; // other datasource

try {
Context ctx = cache.getJNDIContext();
Connection conn = null;
tx = (UserTransaction)
conn = ds.getConnection();
Statement stmt = conn.createStatement();
String sqlSTR = "insert into " + tableName + " values (........ )";
r.put("key", "value");
} catch (NamingException e) {
// handle the exception

KMS Activator for Windows 8.1 and 2012 R2


Are you running with Windows 8.1 or 2012 R2 and looking for KMS Activator ?

Sorry this is not the right post for you. I am just explaining how I got my 2012 R2  activated by Key Management Service (KMS)

Who ever using KMS keys need to add the new ones from  Microsoft  Volume license Service Center


Are you updated with hotfix for your existing KMS server ?

If not you can request for the hotfix(KB2691586) to download from here

Its applicable for

  • Windows Server 2008 R2
  • Windows Server 2008
  • Windows 8
  • Windows Server 2012
  • Windows 7
  • Windows Vista

Get the email and download it then install.

You definitely need a down time window for this.

Run this command as Administrator :

cscript %windir%\system32\slmgr.vbs /ipk

Note :- Each KMS host key is associated with a windows editions so client keys can not be used to Servers.

You will get the below error if  you are trying to add a key which is not matching with editions.

Error message: 0xc004f015: The Software Licensing Service reported that the license is not installed.SL_E_PRODUCT_SKU_NOT_INSTALLEDFor example, you receive this error message if you try to install a KMS host key for Windows 7 on a computer that is running Windows Server 2008 R2.For more information about KMS host keys and about associated groups of Windows editions, see Table 5 in the “Determine Product Key Needs” section of the Volume Activation Planning Guide ( . To activate the new KMS host key on the host computer, run the following command: cscript %windir%\system32\slmgr.vbs /ato

Try this command :  cscript %windir%\system32\slmgr.vbs /dli  to show your registered details and which server etc..

Is your laptop shutting down for no reason ?


Last week was terrific to me because my laptop started to shutting down with out any reason my few files got corrupted. If I am turning on my laptop again it was showing nothing, lights not coming up so totally frustrated, yeah I kept many important project related files in it. 

After an hour my laptop started working simply by pressing power button. somehow I started Google  regarding this issue which is currently stopping my all beautiful works.  I got to know is possible due to cpu overheating.

Now , I started to look for few tools which can help me to monitor cpu temperature. found few tools but I chosen

1. All CPU Meter    from 


All CPU Meter
is the most popular and sought-after gadget on our website and also in the Microsoft desktop gadgets gallery. This gadget shows your processor usage (up to 2 processors, 16 cores, and 32 threads), RAM usage, CPU frequency, and processor name (Intel or AMD). It also includes sound alerts as well as fly out features that display additional information about your processor, operating system, baseboard, bios, and computer system.


2. Core Temp  from


Core Temp is a compact, no fuss, small footprint, yet powerful program to monitor processor temperature and other vital information.

What makes Core Temp unique is the way it works. It is capable of displaying a temperature of each individual core of every processor in your system!
You can see temperature fluctuations in real time with varying workloads. Core Temp is also motherboard agnostic.

Core Temp is easy to use, while also enabling a high level of customization and expandability.
Core Temp provides a platform for plug-ins, which allows developers to add new features and extend its functionality.

3.SpeedFan  from


Speed Fan lets you take a deeper view at the status of your computer. Almost every computer includes support for hardware monitoring. Accessing digital temperature sensors is really useful. If you are trying to figure out why your PC hangs when under heavy load or after some hours of usage, Speed Fan might help you find the real cause. Very often it is a poor power supply, or an improperly installed heat sink that lead to behaviors that we tend to associate (incorrectly) with errors from the operating system. Speed Fan automatically searches your computer for informative chips: the hardware monitor chips. Speed Fan can display voltages,fan speeds and temperatures. On rare occasions, the BIOS doesn't activate such features. Speed Fan tries to enable them as long as this is a safe thing to do. Not only the motherboard is searched, but also some video cards and almost every currently sold hard disk. Speed Fan can access status info from EIDE, SATA and even SCSI drives, consistently showing internal data that can be used to diagnose current and future hard disk failures. This is known as S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology). At the lowest level, the Speed Fan hardware monitor software can access digital temperature sensors, but its main feature is its ability to control fan speeds according to the temperatures inside your PC, thus reducing noise.


Speed Fan allows to change your CPU Clock settings as you wish ( becareful It will hurt your machine by choosing  wrong setting )

Conclusion  :

I have changed Thermal paste after completely clean my CPU & heat sink ,bought cooler pad too, now my CPU’s temp is 40 C to 65 C.

If you already have a cloud backup service, you are most likely paying anywhere from $49.99 to $199 a year!
Read Below To Find Out How Those Fees Come To An End!

Look, if you're a regular over at, you know that we don't typically endorse products – that's not our style. So, you know that when I do break out of the norm and willingly endorse something, it's because I know for a fact that it's worth it to you.

Now, most of you know me as Onuora – the CEO and founder of Who you probably DON'T know is my buddy Rob Boirun (he pronounces that Byron of all things). If you keep reading you'll see that you are about to love this guy as much as I do, he's really hooking us up here.

A few weeks ago Rob contacted me about a new cloud storage service named DrivePop. It didn't sound like anything special when he was explaining it – it enables users to backup the contents of their Mac or PC to the cloud. I thought, what's the big deal? I already have a service like that and there are tons of them out there. Big whoop, right?

Well, get ready for this. Rob starts telling me that he really wants to get news of his service out there and in order to do that, he decided to provide me and all the visitors an exclusive offer.

NO monthly payments, NO recurring billing – EVER!

I bet you're loving Rob now! The thing is, everybody needs backup storage, it's just one of those things that goes along with owning a computer.

Whether you're an individual, a family, or a professional business, you can't have unexpected shut-downs, computer problems, power-surges, or theft destroying your precious and sensitive data and often-times erasing invaluable documents, pictures, and history forever.

It's a risk you just can't take.

So what do we do? We find a good cloud storage service and we pay the yearly fees – year after year after year. Of course, those services know we need them, so they never worry about you leaving.

Yet, Rob is offering all of the same stuff those other high-level cloud storage services are, but instead of paying year after year, you simply pay one flat fee – that's it!

DrivePop offers:

  • Unlimited backup space
  • Unthrottled bandwidth
  • Military grade AES-256 Encryption
  • Ability to stream music and movies from your account
  • File versioning (up to 30 versions)
  • You can view your files online, from any computer, anywhere in the world
  • Control panel and APP access
  • Unlimited computer usage
  • Access from any device (ipad, iPhone, Android, Windows RT, Win 8, Blackberry, etc...)


You're probably wondering by now what the catch is. First of all, I would never endorse a product that has any kind of catch (which is why I rarely ever personally endorse products in the first place).

The reason Rob is offering such a deal is simply because he wants to get the word out about his service. He trusts me and he thinks the people who visit are just the type to appreciate this service.

This is an exclusive offer, which means that not everybody is going to be able to take advantage of this – only you. Not only that, but this is a limited time offer. Rob has a business to run, after all, so he can't offer this deal forever.

Look, there's no pressure here but it's just common sense. You can pay between $500and $2000 within a 10 year period for all those other cloud storage services, or you can take advantage of this one-time special offer from my buddy Rob and never have to pay another yearly fee for backup storage again. Ever.

Rob has also told me to make sure everyone knows that each plan has a 30-day, no questions asked money-back guarantee.If for any reason whatsoever, you decide that you want your money back and that this service is not for you, simply contact his team and they'll issue a FULL  refund immediately. You're not going to have to jump through any hoops. You're not going to have to answer any questions. There are no cancellation fees involved – nothing but a straight-up return.

Now here are what some real life (no BS) DrivePop customers have to say about the service:
