After my previous article on how to install and configure SQL Basic Availability Group now it’s time for WEM Database creation.
Here after are the steps I did to make it working
Prerequisites
Create an empty WEM Database
First you will need to create an empty WEM Database on the Primary SQL Server
- Open SQL Management Studio
- Connect to primary SQL Server, make a right click on Databases and select New Database…
- Provide a name for the DB and click on OK
Create Database on WEM Server
As after we will create a BAG, we first need to create an alias for BAG Name to point to primary SQL Server.
In my case I have done the following
- Create a Host entry for the Listener
- Ensure Listener and primary SQL server reply on same IP
- Open WEM Database Management Utility
- Click on Create Database
- Click on Next
- Provide name of the Listener (created previously in the Hosts file on the server), the Database (created earlier) and click on Next
- If the user is Sysadmin on SQL, just click on Next
- Select an Administrator group, optionally provide a service account, provide a password for vuemUser SQL account and click on Next
- Click on Create Database
- Click on OK
- Click on Finish
Create BAG on SQL Server
After the DB has been created using WEM utility, we can create the BAG
- Select the CitrixWEM database, make a right click and select Tasks > Back Up…
- Ensure that Backup type is Full and click on OK
- Click on OK
- on Always On High Availability > Availability Groups, make a right click and select New Availability Group Wizard
- Click on Next
- Provide a name for Availability group and click on Next
- Provide the vuemUser SQL user account password (set during WEM Database creation), click on Refresh and select the Database. Click on Next
- Provide a Replica and click on Listener tab
- Select Create an availability group listener radio button, provide Listener DNS Name, Port, add an IP for Listener and click on Next
- Select Full database and log backup radio button, provide a path and click on Next
- After validation, click on Next
- Click on Finish
- Click on Close
- Ensure Availability Group is created
Note: as you can see above, on my secondary Node, the database is in Restoring state.
- You need to go on secondary SQL server, develop Always On High Availability > Availability Groups > BAG_Name > Availability Databases, select Database, make a right click and select Join to Availability Group
- Click on OK
- Refresh the console, now the Database state is Synchronizing
- Select the BAG, make a right click and select Properties
- Change Availability Mode from Asynchonous commit to Synchronous commit and Failover Mode from Manuel to Automatic and click on OK
- The Database state on secondary Node will change to Synchronized
We need to synchronize the WEM service account between SQL Nodes, to do so:
- On the primary SQL Server, open an elevated PowerShell command and run Install-Module dbatools
- Run the command: Copy-DbaLogin -Source LAB-SQL-01 -Destination LAB-SQL-02
WEM Infrastructure Service Configuration
- Open WEM Infrastructure Service Configuration Utility
- Provide Listener for Database server, the database name and click on Advanced Settings tab
- Provide a infrastructure service account (need to be member of the local administrator group on the WEM server), provide the password for vuemUser SQL user account and click on Database Maintenance tab
- Enable maintenance and click on Licensing tab
- Provide license server and click on Save Configuration
- Click on Yes and exit WEM Infrastructure Service Configuration
Validation
To validate, we will initiate a Failover
- Within Failover Cluster Manager console, ensure Role is owned by 1st Node
- Within SQL Server Management Studio, make a right click on the primary Availability Group and select Failover
- Click on Next
- Ensure 2nd Node is selected and click on Next
- Click on Connect
- Click on Connect
- Click on Next
- Click on Finish
- Click on Close
- Verify that BAG is primary on 2nd Node and Secondary on 1st Node
- Ensure as well in Failover Cluster Manager that Role is owned by 2nd Node
- Open WEM Administration Console
- Click on Connect
- Provide the Infrastructure server name and click on Connect
- You should connect and see the console
You can do the same for other Citrix products Database like:
- Citrix Virtual Apps and Desktop
- Citrix Endpoint Management
