For my 1Y0-A20 XenApp 6.5 administration exam I’ve used a lot of knowledge base articles and other resources besides the self paced online course (courtesy of my employer).

Citrix CCEE track

After my Microsoft certification track (Multiple MCITP certs) I’ve now set my aims to the Citrix CCEE track. CCEE is short for Citrix Certified Enterprise Engineer. This is the next step after you receive the CCA and CCAA status. You can hold multiple CCA certifications for the different Citrix products. I have set no timeline for myself to get this status but I will do everything to get this done in a reasonable time frame.

I will try and collect as much as information possible to prep for the different exams and post this here. If anyone has some good tips and information which they are willing to share please leave a message on this post.

For everyone who doesn’t know what exams to pass I’ve taken a grab of the official Citrix education site with the information on this certification track. Continue reading “Citrix CCEE track”

How to Isolate Web Interface or Program Neighborhood Agent Sites into Their Own Application Pool for Best Performance

When Web Interfaces sites or Program Neighborhood Agent sites are part of a large deployment and are the primary method of accessing applications for an organization, you might consider isolating each Web Interface site or Program Neighborhood Agent site into their own IIS Application Pool.


Each separate Application Pool provides a process boundary so that when a Web Interface site or Program Neighborhood Agent site is assigned to one application pool, problems in other application pools do not affect the application. This ensures that if a Web Interface site or Program Neighborhood Agent site fails, it does not affect the other Web Interface or Program Neighborhood Agent sites running in other application pools.

The process to create an Application Pool for Web Interface or Program Neighborhood Agent site is as follows:

Note: Before performing these changes, ensure that no users are accessing the Web Interface or Program Neighborhood Agent sites because their access will get interrupted.

2. Fixed: Gestures guide incorrectly includes both a check box and toggle switch when rotated – removed the redundant switch.

3. Fixed: VPN session continues to run when Access Gateway has timed out – VPN session discontinued when Access Gateway session times out.

New Receiver for IOS released

Citrix has released a new version of the Receiver for iOS (version 5.6.2). This version is now available in the App Store.

New or updated features are:

1. HTML5 application performance enhancement – some HTML5 applications report an extensive slowness while loading the application.  The fix addresses this delay to improve the speed with which the HTML5 applications launch.

2. Improved refresh applications experience – while Receiver is loading or refreshing the application during enumeration and a network error occurs, the Receiver would crash or display invalid error messages.  This addresses both the crashing issue and displays an appropriate error message.

3. Improved support for VDI-in-a-box – issue arises while tapping the logon button when using a WebInterface Account to log onto a VDI-in-a-box solution.  There was not response from the tapping on the logon button.  The logon experience was improved for VDI-in-a-b0x infrastructure.

Fixes in the release are:

1. Bug fixes related to the URL generator base configuration – several bugs for the processing of a URL generated configuration link were identified.  These issues are addressed in this release.  The URL Generator configuration tool is again supported for the iOS Receiver.

2. Fixed: Web Interface with Access Gateway authentication (blank screen) – after manually configuring a WebInterface plus an Access Gateway site, the logon procedure generates a blank screen instead of the Receiver Home Screen.

3. Fixed: Secure browse works consistently on cellular networks – the Secure Browse application within the Receiver would freeze or crash randomly on some cellular connections.

4. Fixed: XenDesktop and virtual keyboard launch – the virtual keyboard was popping up automatically even if dismissed.  The behavior was modified to honor the settings.
