Book review – The Tipping Point

Wow, this has got to be one of the most though provoking books that I have read in recent times. “The Tipping Point” by Malcolm Gladwell sets out to explain those moments when ideas, trends and social behaviours cross a threshold and then spread liek wildfire.

The book raises many, many though provoking ideas. Ones of these is that you can measue a persons intelligence directly from the people that they associate with. Most people closely associate with people who are like them, move in similar circles, do the same thing, come from similar backgrounds. People who have a wide range of associations, even loose or weak ones, generally tend to be far more intelligent because they are mingling with people who are not like them. They are challenged by these differences and that greatly increases their abilities. It can also be shown that the more contacts people have the greater their intelligence since they have to continue to juggle these associations and social interactions. Interesting eh?

Gladwell identifies three personality traits that required to cause a tipping point. Each is unique but a necessary component for any trend to move into the mainstream. He cites many examples, like the growth in popularity of Hush Puppy shoes, the success of Sesame Street and the influence TV news readers had in recent Presidential campaigns.

If you want a book that will really make you think and take a hard look at what makes things tick then I can’t recommend this book highly enough. It is rare that a book these days can so stimulating. In my opinion this is a must read book!

Now we Youtube as well

We were getting a bit tired of doing a video, then converting it to and .exe so it included the codec, then uploading both versions to our blog and trying to explain why they were both there, and yadda, yadda, yadda. Then we thought, hey get with the times man, Youtube it !

So now you’ll find all our videos up on Youtube. The latest one on the benefits of a RAID hard disk system for servers can be found by clicking here. If you want to locate the rest of our Youtube video doa search on the ‘tag’ sbs2003 or saturnalliance.

Youtube is great ( provided the video is less than 10 minutes ), you simply upload and you’re away. The more we think about it the more we see the commercial potential behind Youtube. No wonder Google shelled out US $ 1 billion.

Etrust antivirus slowdowns

We have now seen this a few times so …

If you have Etrust antivirus V7.0 installed on your machine you may experience a situation where the whole system runs extremely slow after the change to daylight svings time ( DST ). A bug exists in the Etrust software that allows Inotask.exe to run at 100% CPU utilization. The resolution is to apply an update from CA which can be found here.

Basically you download the file, unzip it ( using the CA unzip program ) then stop all the Etrust services. Next, replace the files on the affected machine. For a server there will normally be 2 files to replace an don workstations just one. Restart the Etrust services again. The CPU should now return to normal levels.

The strange thing that we have found is that only certain machines are affected. Sometimes servers ( SBS2003 included ) and sometime workstations. No rhym or reason. Go figure.

SharePoint success

Ah ha. Turns out that after your install Dot Net 3.0 on your SBS2003 server ( prior to installing SharePoint 3.0 ) you need to reboot even if it doesn’t ask you to. For some reason our initial install didn’t ask for a reboot and we proceeded on with the SharePoint 3.0 installation.

So there you go. Step 1 – install Dot Net 3.0. Step 2 Reboot, Step 3 install SharePoint 3.0 and then carry on with the configuration.

We are happy to say that it is all up and running now and we are happily working with SharePoint 3.0 on SBS2003R2.

Failed to create empty document

Just found that you get this error “Failed to create empty document” when you attempt to open the Arcserve Brightstor Manager when using Remote Desktop connection to your server after installing Internet Explorer 7.0. Computer Associates have a knowledge base article here but basically :

1. Shutdown the Brightstor Manager

2. Rename the file psapi.dll located in :\program files\ca\brighstor arcserve backup to psapi.dll.org

3. Restart the Brightstor Manager

Simple eh ?

Making USB keys read only in XP SP2

As usual, the normal warnings about using regedit apply. If you use regedit incorrectly you may cause your system to fail to boot.

1. Run Regedit

2. Locate HKLM\system\currentcontrolset\control

3. Right mouse click on Control and select New Key

4. Enter the new key names = StorageDevicePolicies

5. Right mouse click StorageDevicePolicies, select New then DWORD

6. Enter value WriteProtect

7. Set this value to 1 to allow USB drives to be read only or 0 to allow normal USB operation.

Arcserve job that won’t run

Have you ever seen a job in Brightsor Arcserve that is correctly scheduled but won’t run? If you have a look at the job closely in the Job Status screen you will see that, most likley, the backup job doesn’t have a Job ID number. All this indicated that the Job Queue has become corrupt and needs to be recreated.

Prior to any changes it ius always a good idea to save your existing backup job to a file. Simply right mouse click on the job in the Job Status screen and select “Modify Job“. At the modify job screen selecet File | Save As and save the backup job.

So, the first step is to stop all the Brighstor Arcserve Engines. To do this simply right mouse click on the three green circles in the top middle of the Brightstor Manager and select “Stop all Engines”. After a few moments all the indicators should go to red. You can also stop the engines via Services in Administrative tools.

Now locate the :\program files\ca\brighstor arcserve backup folder on your hard disk. Under this folder is a queue directory, which looks something like 000000001.qsd. Right mouse click on this and rename it to something ( ie 00000001.bak ).

If you return to the Brighstor Manager and right mouse click on the three red circles and select “Start all Engines” from the menu that appears. A new queue ( and directory ) will now be automatically created. The queue will be totally empty ( of even a database prune job ), so you’ll need to re-create both your backup job and the normal database prune job. To recreate the prune job you will need to go into “Server admin” and follow a few steps to recreate the standard prune job (I’ll run over this in my next post maybe). If you saved your backup job out previously then you can simply create a new backup job and restore it from the file you saved previously.

Beware that if you are using an autoloader, once you create a new queue and recreate the backup job the link between the media pool and the backup job is broken. You will therefore need to move the media in the autoloader into the correct pool set (scratch or save). We have found issues doing this and recommend that the best bet maybe to erase the tapes one at a time so they are blank. A blank tape should get picked up automatically, reformatted and placed in the right media pool. We also found that sometimes you need to restart all the engines again to get Brightstor to accept the newly created blank tape. Why? We don’t know but we do know that starting and stopping the engines have fixed our problems.

Recreating Arcserve Database Prune job

You asked for it, well here it is. if you have blown away the Brighstor Arcserve queues then you will usually need to rereate the Arcserve database pruning job. This is a regular maintenance program that Arcserve runs that removes old records from the backup database into which Arcserve records all manner of information about each backup it runs. As you can imagine this can get pretty big after a while, so the pruning job ensures that it doesn;t consume your whole hard disk.

To recreate the pruning job :

1. Open Arcserve Brightstor Backup Manager

2. Select Quick Start | Server Admin

3. Brightstor Arcserve Backup Server Admin should now appear. Select the Database Engine tab

4. Now select Admin | Configuration from the menu

5. The Configuration window whould now appear. Check the option to Enable Database Pruning. Set any parameters that you need, the default option of 30 days is usually fine. Also select at which time you wish the prune job to run ( not when the backup is running generally ). Leave the Delete media related database records option unchecked.

6. Now check the Submit Prune Job option and press the OK button

7. Close the Brightstor Arcserve Backup Server Adim window and return to Arcserve, where you should now see you prune job
