This week i had the honor to test a G2-Series HP I/O-Accellerator Card.
Installation and Post-Configuration of the card is very easy. So you could go ahead immediately with testing these Hot Stuff.
We configured the card to 50% Performance, so we loosed 50% of the available space on the I/O-Card. But for our reasons, to put the TEMPDB of MS SQL-Server 2008 R2 and an Archive log of an ERP-System database on it, shoud this be space enough.
So here are the test results. I don’t wan’t to comment to much. Look at the results. They are self explaining.

Hey Guy’s
here i am with my 1st SQL-Server Post!
If you want to know the membership of a database role, to what other database roles the role
belongs to, i have a good satatement for you.
SELECT dbrole1.name AS dbrole1_name , dbrole1.principal_id , dbrm.role_principal_id , dbrole2.name AS dbrole2_name FROM sys.database_principals AS dbrole1 JOIN sys.database_role_members AS dbrm ON dbrm.member_principal_id = dbrole1.principal_id JOIN sys.database_principals AS dbrole2 ON dbrole2.principal_id = dbrm.role_principal_id WHERE dbrole1.name LIKE '<db-role name>' ORDER BY dbrole1.name ASC
I always recommend colleagues to read and watch the thread on sysadminslive.com about the Facebook IT Mangement and Operations strategy.
Because the using good tools and ideas to observe there system.

Hey Folks!
currently i’m on the way to deploy a Windows Server 2008 R2 terminal server farm. One server is already up and running productive and the other is one step before going online. I work a lot of with GPO’s and user roaming profiles, to ensure to have excatly the same configuration on the new server for all users. Also i use control panel restrictions to display only neccessary .CPL’s to the user.
And one special control panel addin, what is shipped with the MS Office suite ML32CFG.CPL (responsilbe for configuring MS Outlook MAPI Profile), i discovered how important it is, to ensure that applications have to be installed in the same order as on the other terminal servers. Why, you may ask….because, of the 8dot3-names (8.3) and the windows internal file/path handling. In some cases the OS calls an an application it tries to use the 8dot3 path / name.
The control panel addin on the new server was registered successfully during the installation, and i could open it. But if i tried to open the CPL with my test user, what is already using the saved roaming profile, the addin would not open. Also the icon in the control panel window was different against to the other server.
So what happend? With Sysinternals Process Moinitor (PROCMON.EXE) I did a little bit research on both servers, and found out that the 8dot3 name of the MS Office path between both servers is different because i didn’t keep in mind the order, how i installed the applications on the new TS.
Server 1: (C:PROGRA~2\MICROS~1\Office12\MLCFG32.CPL)
Server 2: (C:PROGRA~2\MICROS~2\Office12\MLCFG32.CPL)
To solve the problem, i had no chance uninstall the application what occupies the 8dot3 name, uninstall office and reinstall office and the other application again. After reinstalling MS Office suite, the right 8dot3 name was assigned tho the new installation.

Thank’s Daniel for that helpful information.
A long time ago, but now it’s here!everyone knows it’s very annoing if you have to login to multiple websites during work days. It would be much easier to have a tool tool, what helps us to automate the login process to websites like Amazon, Facebook, Microsoft, Onlinebanking, etc.., where i am registered to. That would safe time and increases workflow and you don’t need to consider about passowrds anymore. Before this article i used a very simple tool to manage my passwords. I also heard and tested Keepass in the past, but it brought no advantage on my workflow.
Now I found this tool Read more…
