As we can download SCOM 2012 RC from Microsoft, I decided to do quick installation in LAB environment. Whole test environment is based on VMware Workstation 8. Deployment of SCOM 2012 will be spread across few servers to separate certain functions (in fact similar to real-life deployments). For SCOM2012 deplyoment I will use following servers:

• lab-dc-01 – Domain Controller – Windows Server 2008 R2
• lab-sql-01 – SQL Server – Windows Server 2008 R2 + SQL Server 2008 R2
• lab-net-01 – SCOM 2012 Management Server – Windows Server 2008 R2 + SCOM 2012 Management Server
• lab-wks-01 – SCOM 2012 Management Console – Windows 7 x64 Ultimate + SCOM 2012 Management Console

This will be mainly screenshot tour through installation phases of SCOM2012.

Here is schematics of the lab:

Sometimes would be nice to hover over land of Skyrim and watch everything from above or even take some pictures of cities and places from sky. But how to do that?

When Yii-based project doesn’t want to update, there might be missing component.

Once you add one plugin everything goes back to normal.

[root@arb-srv-01 easyforms]# composer update
Running composer as root/super user is highly discouraged as packages, plugins and scripts cannot always be trusted
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

Problem 1
- yiisoft/yii2 2.0.7 requires bower-asset/jquery 2.2.*@stable | 2.1.*@stable | 1.11.*@stable -> no matching package found.
- yiisoft/yii2 2.0.7 requires bower-asset/jquery 2.2.*@stable | 2.1.*@stable | 1.11.*@stable -> no matching package found.
- Installation request for yiisoft/yii2 2.0.7 -> satisfiable by yiisoft/yii2[2.0.7].

Once you install Ubuntu 18.04 some packages might not be found by default in repositories (example: php7.2-fpm).

If you want to have more packages available just add repository with more packages available 🙂

sudo add-apt-repository universe

Now you can enjoy more standard packages available.

In one of the previous articles I did quick overview How-to Install vSphere Hypervisor ESXi 5 on VMware Workstation 9. One of the reasons I did that in my Lab environment was to run Cisco Nexus 1000v with NX-OS on it and evaluate this operating system and how it can integrate with other products.

Background image on logon screen os common issue with pre-installed servers, for example from Dell. That makes accessing those systems via Remote Desktop painful and slow (it happenes that serer is shipped to location, racked and stacked, and then whole configuration take place remotely). By default background bitmap from logon screen is sitting in C:\Windows\System32\oobe\info\backgrounds, so you can put your own logon screen background or if you don’t want to have any (just system default) you can follow instructions below and remove background from logon screen.
