Cloud Computing or is my head in the cloud?

Monday, April 2nd, 2012

Cloud computing. A phrase which seems to be found everywhere these days. One can not read anything on the Net or a computing magazine without some reference to the cloud. Even now you will find software with cloud access to backup your work and important files.

One can easily get the impression the cloud is here to stay. The question one should ask is what does it mean for me? Especially if you work in the IT industry.

All to often I see coworkers and associates become intransigent in their ways. Sometimes I wonder why? In the last couple of decades there has been a great deal of  change. People should be used to change and yet I still hear arguments of the cloud being a fad which will pass. After all who would trust their company secrets to an unknown third party? Security is the major concern of the cloud and what’s interesting I have heard the more “free market” minded people who basically think unknown third parties are safe because why would they jeopardize their business? Security will be an ever growing importance to the cloud.

One of the main motivators I hear for migration to the cloud is to lower the cost of computing. Sometimes I wonder if CFOs (IT usually fulls under their control) simply disk like IT. Lowering the cost of computing seems to be a battle cry for most of them these days. It seems all the savings of the past are forgotten and whatever the cost of the moment is too high. The cloud seems to be their latest attempt to eliminate IT costs.

As in the past if “savings” is the guiding force for migration to the cloud, there will be many problems as was seen in the past with outsourcing and offshoring. The cloud is not something a company can leap into without a great deal of planning. As with the previous attempts to cut costs, there are risks for doing it and yet there will be risks if you don’t.

What does the cloud really mean for IT? Well? this is a question which would cover several posts to discus in detail.  I recently read IT Operations Needs to Evolve to Support Cloud out of curiosity to see what would be the evolution. It wasn’t really explained as to what you would need. Simply the main point was to embrace it, read about it and possibly train for it. Not exactly new information for a “seasoned” IT professional who has lived with change for many years.

An interesting comment was the claim which IT departments were not optimized for the cloud. Such departments were old fashioned or as they were labeled “legacy.” I can see this claim as I would suggest these departments are of the mindset of knowing what is best for the company in the matters of IT rather then viewing it’s purpose as enabling and empowering the user community.

When an IT department acts to enable and empower the workforce; it will be “optimized” for the cloud.

Another interesting comment was the claim of the cloud will grant the ability to move to locations based on need.  Some would say this increases competition while others would suggest chasing the cheapest labor possible.

If you believe in the latter, then I would suggest not to fear the coming change.  Take a look at what you do. Are you specialized? If so, it might be time to increase your knowledge in other areas. The question as always is which areas? I have read a few opinions and about the most common suggestions are network, security, virtualization, and have a grasp of storage.

It will be interesting times in the future and I am looking at more cloud opportunities  to be ready.

Windows 2003 NTP sync looses 1 hour

Monday, March 26th, 2012

I have a new server running windows 2003 R2 to support legacy software.

The server sits in a secured room which does not have access to the Internet. As such it was installed by DVD.

The operating system included service pack 2.

When it came time to configure NTP(we have an internal clock), the time would adjust one hour backwards.

I checked the the following:

  1. Time Zone.  Correct
  2. Automatically adjust clock for daylight saving changes is checked. Correct
  3. The BIOS clock.  Correct
  4. The time server is accessible. Correct.
  5. Patch levels.  Possible problem.

I remembered the time when the government decided to extend daylight savings time and decided a patch was missing.

I searched the Microsoft site and found KB955839

I installed the patch and my time synchronization was correct.

Lesson of the day: Don’t assume the service pack has all needed patches.

Remote Desktop command keys.

Sunday, March 25th, 2012

After posting Where is ctrl-alt-delete I thought it might be a good idea to list the remaining key combinations for remote desktop.  You may not use all of them but it’s good to know they exist.  Microsoft was good enough to provide the following:

 

Shortcut key Description
ALT+PAGE UP Switches between programs from left to right.
ALT+PAGE DOWN Switches between programs for right to left.
ALT+INSERT Cycles through the programs in the order they were started.
ALT+HOME Displays the Start menu.
CTRL+ALT+BREAK Switches the client between full-screen mode and window mode.
CTRL+ALT+END Brings up the Windows Security dialog box.
ALT+DELETE Displays the Windows menu.
CTRL+ALT+MINUS SIGN (-) Places a snapshot of the active window, within the client, on the Remote Desktop Session Host (RD Session Host) server clipboard (provides the same functionality as pressing ALT+PRINT SCREEN on the local computer).
CTRL+ALT+PLUS SIGN (+) Places a snapshot of the entire client windows area on the RD Session Host server clipboard (provides the same functionality as pressing PRINT SCREEN on the local computer).

 

Where is ctrl-alt-delete for remote desktop?

Saturday, March 17th, 2012

If you have worked with windows for a period of time, one of the most common used keyboard command sequences is ctrl-alt-del. In the old days, this was one of two solutions to fix many problems of Microsoft; reboot.

Nowadays, you would use it to start the task manager or lock the desktop.

Microsoft eventually blessed us with Remote Desktop. A great tool for remote access but there comes the time when you need ctrl-alt-del.  You enter it and quickly discover it only works for the local session.

For some reason, it was not obviously documented and I tend to forget it as I don’t use it that often. Probably because it doesn’t make sense. This option seems to be based on “whoops, forgot about that…..why don’t we just use…..”

To enter a remote ctrl-alt-del, you would enter:

ctrl-alt-end

LSF will not re-install

Saturday, March 17th, 2012

There was a case were an LSF installation had to be reinstalled on a Windows 7 machine. We ran the uninstall and deleted the LSF folder from the C drive. However, when attempting the re-installation; we received a message about the LIM service already running for the cluster.

Checking the services; I found Platform LIM still listed. Normally you would also see Platform RES and Platform SBD.

The suggested solution was to re-install the system. This was not attractive as the build process takes time to configure and verify for production.

My first thought was the service was keeping the installation process from running. The question was how to remove it?

After a little search I found the sc command which allows you to use the command line to interact with the Service Control Manager and Services.

The command needed:  sc delete [service name]

Now what would be the service name? If you return back to the services interface and double-click Platform LIM, you will see the service name which is : LIM.

You can also use the sc command by entering: sc query | more

This will list all services. Look for Platform LIM and above it will be the service name.

After I found the service name; I entered:

sc delete LIM

The service went away and the LSF installation was successful.
