Netscaler Gateway 12.0 Force failover (Command line - Force Failover)


The Force failover did not work due to permission issues.

Problem with password.

We worked on the test environment.

Working in his laptop. Password issue/UPN is working/Tried with AMCS LDAP. We try with EMEA authentication.

After change in permissions at the AD LDAP level, we were able to force fail over and the Services were running fine on the Primary Netscaler Gateway 12.0

Lessons Learnt - Xenapp and Xendesktop 7.15 Long Term Service Release - September 2017


1. Why upgrade from Xenapp 6.5

End od Maintenance - Dec 2017
End of Life - June 2018
EOLExtended Support - Jan 2020

Common Upgrade Challenges

1. Picking a Version - Long Term Service Release vs Current Release.

2. Translating feature between IMA and FMA
Zones
LHC
Advanced Application Mgmt

Agenda -
Versioning - LTSR vs Current Release.

1. Citrix Cloud Releases. - Always the latest.

2. Current Releases - New Feature Releases

3. Long Term Service Releases - Predictable release Cycles...

Comparing Release Offerings.

1. Customer success services required.
2. Product Lifecycle timelines.

Lifecycle -Policy Updates - Current Release.
Long Term Service Release -

Product -
Xenapp Xendesktop - 7.15 LTSR -- 15 Aug 2022 --- 15- Aug - 2027
Xenapp Xendesktop - 7.6 LTSR  -- 11 Jan 2021 --- 11- Jan - 2026

Key Lifecycle 7.15 LTSR Considerations.

1. Xenapp & Xendesktop 7.15LTSR supports Windows 2008 R2, 2012 R2, and Win 2016

2. LTSR VDAs can be mixed with a CR Site .






Feature Translation --

IMA:FMA:: LHC ??
Zones: What are they ?
A Zone in Xenapp 6.5 is a subset of a farm. that containts session hosts
and controllers.

A Zone in Xenapp 7.x is a subset of a Site, that contains VDAs and
optionally Delivery controllers, which communicate to a centralized
SQL database via a Low latency connection.

Two types of zones are available: Primary and Satellite.

Pre 7.7 VDAs do not honor Zone designations and will accept all requests.

POD Architecture is Not Dead.

Failure and update domains are still a factor.

Just because we have zones, does not mean we should deply single.
global sites.

Zones are another tool in the toolbox.

Local Host Cache: What is it?
In Xenapp 6.5 this was a cached copy of the farm datastore.

In Xenapp 7.x, this is a SQL LocalDB Database that exists.
LHC allows continues for continued user connections
