Client: Cap Gemini Branch: ICT
Period: August 2007 – October 2007
Project: Horizon (ROC Horizon College)
Target: Changing The Horizon College from an internal ICT management to outsourcing provided by Cap Gemini.
Tasks: Making available applications in the new production environment. Applications are delivered as MSI (distribution using SMS) or as a virtual application (distribution using Softgrid). Applications are delivered in the FAT (Functional Applications Test) environment and need to be made available in production. This needs to be done in accordance with procedures and with tools provided by Cap Gemini. Besides precisely following all the steps of the procedures, my troubleshooting skills are being put to the test in case a application doesn’t functions as expected. The solution is mostly found in the connectivity to backend systems of dependency of other (third party) software. Tuning GPO’s and Citrix policies.
results: Applications are being transferred to production and therefore problems are solved.

Period: July 2006 – august 2007
Target: Sequencing, repackaging or unattended installation of applications. Applications are to be made available virtual on Citrix server as much as possible. Sequencing software using Softgrid, collect software (in the various departments), testing of software, check and where necessary complete the documentation of software installation/configuration/contact information. Publication of software using Powerfuse, when necessary distributing software using Altiris. Policy configuration using AD and Powerfuse. Profile problems are minimised by using mandatory profiles and the Flexprofile kit. Server deployment with the help of Altiris. Creating distribution jobs for Altiris in a way that servers and silo’s are correctly installed. Sizing servers in a way that servers perform as agreed. Management and tuning of policies, partly in AD, partly in Powerfuse or by using the Flex profile kit. Deliberate with network management and database management on how applications and backend servers best can be installed. Farm management deployment of Citrix and Altiris.
results: Various police districts are migrated to K3.

Project: Citrix MF XPe
Target: Universal, stable, manageable Citrix-environment
Tasks: Coordinate and execution as technical specialist. Standardize, automate and document of install procedures. Installation of Citrix application servers.
Migration of Citrix applications running on MetaFrame 1.a and Windows NT4 to the new environment running on Window 2000 and Citrix MS XPe. Migration of user from NT4 to NT4 and form NT4 to AD. Creating and maintaining a user profile which can be used for multiple Citrix environments. Packaging of applications that need to run on terminal server. Applications are being packaged with Wise for Windows installer (MSI packaging), we also worked with Wise Install Master.
results: Applications and departments are migrated to the new environment. We created a universal and modular way of installing servers. With the new way of installing servers we shortened the install time drastically. Because we automated the installation of the servers we achieved an homogeneous server environment which resulted in a manageable farm. Also the latest updates are added to the installation procedure so al servers are up-to-date. After testing, these updates are also distributed to the servers already in production.
