If you want to change license server name in xenapp 6.5, open server role manager, edit licensing option then update your new license server name, click next and apply, and reboot.
We have seen an issue in xenapp 7.6 where some of the vms are shutdown automatically after weekend reboot. After lot of research on the delivery controller, we have identified that Delivery controller is sending the shutdown command to some of the vms(random vms every week) and esx is shutting down the vms. So we have decided to turn off power management completely in our xenapp 7.6 environment.
Here are the steps to set your power management to max for all delivery groups.
While using the imaging wizard, after rebooting the target device, it throws an error saying, Failed to snapshot instead of uploading OS into PVS vdisk.
Solution:
Enable Microsoft Software Shadow Copy Provider and Volume Shadow Copy service services. Set them to automatic.
Problem Cause:
Imaging Wizard and P2PVS require the source virtual machine to have both Volume Shadow Copy and Microsoft Software Shadow Copy Provider services enabled to perform an imaging operation.
As per the pvs image wizard process, you install pvs target device setup on a machine and run image wizard to push the OS into a vhd(or vhdx in xa7.7) file. For this you need to reboot your target machine. After reboot at the conversion step, it says creating snapshot, and immediately it throws an error saying, Failed to create snapshot. Upon viewing the log file, i saw a line, which says “Failed to InitializeBackup.
As a part of reboot schedule, which is a inbuilt feature of xenapp 7.6, DC would send message to users before the time we set, and then logoff users from the servers and reboot. Recently I came across a task to send message to users and logoff users from a particular delivery group So, I wrote a powershell script for the same. Details given below:
Copy all the server names in the delivery group to serverslist.
Checkout the script to enable and disable maintenance mode on xenapp 7.6 environment.
Script:
1 2 3 4 5 6 7 8 9 10 11 Function Global:Enable-MaintenanceMode([string]$servername) { Add-PSSnapin citrix* $name = (Get-BrokerSharedDesktop -HostedMachineName $servername).MachineName set-BrokerSharedDesktop $name -InMaintenanceMode $true } Function Global:Disable-MaintenanceMode([string]$servername) { Add-PSSnapin citrix* $name = (Get-BrokerSharedDesktop -HostedMachineName $servername).MachineName set-BrokerSharedDesktop $name -InMaintenanceMode $false } Usage:
Enable-MaintenanceMode -servername SERVER
Disable-MaintenanceMode -servername SERVER
I recently came across a task to check all the unregistered vms in xenapp 7.6. I got the infomation and send email manually. I thought of a script which would do the same and came up with below script:
Script:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 Add-PSSnapin citrix* $smtpServer = "MAILSERVER.
Problem: One of the user’s contacted me saying he is not able to type the character “P” in his citrix session. Desktop has been published and when typing the password, he got this problem.
Solution: User’s session is still active on the server. Informed user to logoff from all his citrix applications. Cleared cookies in IE. I have manually logged off the sessions which are still there on the server. User logged in again, issue resolved.
Sometimes in user’s pc, already .ica files have been set to open with some other apps by mistake. I recently came across an issue in one of the user’s pc, .ica was set to open with adobe reader. When user logs in to netscaler and clicks any app, it says, adobe reader cant open this file.
I have seen that there is no receiver installed in user’s laptop. Installed it and restarted laptop but still it is going to adobe reader only.
