5 Top Questions about SCOM + OMS

There is a lot of debate surrounding SCOM and OMS. The common belief is that OMS is competing against SCOM, and many people seem to think that OMS is still SCOM in the cloud, or that they are both doing the same thing. But is OMS the same as the Microsoft System Center Suite? Is OMS really a replacement for Microsoft System Center?
Savision’s newest eBook is written in collaboration with Microsoft MVPs Dieter Wijckmans and Thomas Maurer. It compiles the 5 top questions regarding SCOM and OMS, and provides you with the answer, directly from the experts. In this eBook, you will find out:
1- What is OMS?
2- Is OMS replacing System Center?
3- What are the main differences between SCOM and OMS?
4- Do you still need SCOM?

Backup and Recover Oracle Database Using Veeam

In this post, we are going to show on how to backup oracle database & recover database using Veeam Explorer for Oracle.

[Pre-requisite]
Configure achieve log mode on oracle database before configure backup. Please refer to http://www.ms4u.info/2017/07/configure-oracle-archivelog-mode.html

[ Backup Configuration ]

On Guest Processing page,
1. tick "Enable Application aware processing"
2. On Guest OS Credential, enter local admin authentication

Click on Application button


On Oracle tab,
3. Enter Oracle account with SYSDBA credential (full right)
You can configure an additional setting on archived logs.
We set to backup log every 15 minutes for testing purpose.

Run backup and at the end, result will consists of:-
1. Virtual image backup
2. Transaction log backup


[ Recovery Configuration ]

Open Veeam Explorer for Oracle

 Before we start recovery, change setting to point to target server/staging server. Go to Top Left | Click Options

Enter target server
A - Target IP or Server Name
B - Enter local admin credential
C - Click browse to select Oracle Home.


If credential is correct, system will display result else you will get an error message " The Username or password is incorrect"




Here is the recovery process video:-


Enjoy!

Configure Oracle ArchiveLog Mode

In this post, we are going to configure archive log mode before backup Oracle database using Veeam Backup & Replication

Open SQL Command Line

Execute below command to configure archivelog mode



1. Connect to Oracle
connect / as sysdba

2. View database log mode
Select log_mode from v$database;

3. Shutdown the database before configure archivelog mode
Shutdown immediate

4. Startup the database in mount mode
startup mount

5. Set ArchiveLog mode

Setup of a Disaster Recovery (DR) site in Microsoft Azure using Lightweight, Software-Defined Networking (SDN) - Part 2

In the previous post, we've talked about how to use Veeam PN to setup site to site VPN from on-premise to Microsoft Azure. Next, we will look on how remote client from external access the resources securely to DR Site (located at Microsoft Azure). To do, you need to download OpenVPN Client from here:-https://openvpn.net/index.php/open-source/downloads.html

my lab scenario:-


[Scenario Point to Site VPN]
1. Power on Veeam PN Appliance (act as Network hub) on Microsoft Azure. We have temporary turn it off to save Azure credit. VM @ Microsoft Azure which has stopped (deallocated), do not incur compute charges except storage consumption)
2. Access to Veeam PN Appliance, create a new client. (Click on Clients | Standalone computer) and download the configuration file (user.ovpn)



3. From OpenVPN Client, import the configuration file

4. Click Connect


5. Once connected, try to access VM which located in Microsoft Azure using private IP.
Example: - RDP
You able to tracert & ping using private IP as well.



On Veeam PN - Network hub appliance, you can monitor the status mentioning client is "Connected"

That's concluded our testing on remote client access securely to DR located at Microsoft Azure using Veeam PN.

Setup of a Disaster Recovery (DR) site in Microsoft Azure using Lightweight, Software-Defined Networking (SDN) - Part 1

In this post, we are going to explore a lighweight software defined network (SDN) using Veeam PN to setup site to site VPN.

Veeam PN is a free Veeam solution that supplements the Veeam functionality of restore to Microsoft Azure and allows you to create a VPN connection between remote sites over the public network. You can use Veeam PN to implement the following scenarios:

  • Set up a site-to-site VPN between company offices and a Microsoft Azure network to which VMs restored in Microsoft Azure are connected.
  • Set up a point-to-site VPN between remote computers and a Microsoft Azure network to which VMs restored in Microsoft Azure are connected.
  • Allow remote users to get access to a company network through a Microsoft Azure network.

Veeam PN lets you set up VPN connections between Microsoft Azure networks and on-premises networks.

The solution is based on the OpenVPN technology and features a web-based interface that simplifies VPN configuration and administration.

In the VPN, all traffic between remote networks is routed over a secure communication channel — VPN tunnel. To establish a VPN tunnel, Veeam PN uses its appliances:
a) network hub - Network hub is the core of the VPN which is responsible for traffic routing, encryption, user management, authentication and so on.
b) site gateways- is a virtual appliance that establishes a secure connection with the network hub.


Here is my lab environment simple environment:-



[Scenario 1:- Site to Site VPN]
To configure S2S VPN, perform the following configuration:-

  • Deploy & configure Network Hub on Microsoft Azure


a) Network Hub Appliance in Microsoft Azure
Go to Azure MarketPlace:- https://azuremarketplace.microsoft.com/en-us/marketplace/apps/veeam.veeampn?tab=Overview
Using 192.168.20.0/24 Subnet on Microsoft Azure
Follow simple wizard to deploy the appliance from Azure MarketPlace. Once done, use the assigned public ip to access the appliance (https:\\veeampn public ip) & login using the credential which you've defined when create the appliance.

 This is how it look like after login in.


  • Register Veeam PN client
Go to Client
Click Add, select Entire Site
Enter Subnet 192.168.0.0/24 (on-premise subnet)

  • Deploy and Configure Site Gateway on on-premise

b) Site Gateway
Download free Veeam PN OVA package from https://www.veeam.com/cloud-disaster-recovery-azure.html and setup on-premise
Deploy it on-premise
Using 192.168.0.0/24 Subnet
Login to the virtual appliance using the following credential to get the ip address

  • username: root
  • password: VeeamPN

(use ifconfig cmd, the appliance is running on Ubuntu OS)

Use browser to login to https://veeamPN IP
Change the password
Initial configuration wizard will prompt
Select "Site Gateway"
Select the Configuration File that you've get it from Network Hub Appliance

  • Add static route for outgoing traffic on default gateway
Below result indicated that our traffic is still routed to old gateway (firewall). We need to add static route for any request to 192.168.20.0/24 should route to 192.168.0.253.



Use command "route add 192.168.20.0 mask 255.255.255.0 192.168.0.253"


Perform ping test to 192.168.20.5 (Azure VM). Result from tracert showing that traffic is now route to 192.168.0.253 (Veeam PN-Site Gateway Appliance)

Lastly, on Veeam PN (Network Hub @Microsoft Azure) dashboard is showing traffic in and out for both network.


That's concluded on our simple test on setting up site to site vpn between on-premise & Microsoft Azure using Veeam PN.
