This is the automation of a full Windchill build using Jenkins Master/slaves. There are three red hat Linux machines and one windows machine. Of around 70+ installers that Windchill build delivers, this continuous integration build needs all installers to tests. All required modules/artifacts are delivered to the central location from where they are picked up to create the installer. Separate Clearcase views/Git Repositries run on different slave machines to build each installer. Once the module-building jobs finish building the required artifacts needed to create an installer, it starts executing the installer Job. This process is applicable for all the required installers needed for the initial smoke tests process. I also developed a mechanism of installing the Build/Installer on the Testing System. Once each Continuous Integration build gets built it starts the installation process on the Continuous Integration testing environment. testing process so that the build can be used by the QA team to verify the Windchill Builds.
Responsibilities
Design and maintain continuous integration environment for all Windchill Releases.

Delivering a customer patch is one of the highest priority operational task in our team. In this process we have to deliver bug fix/enhancement/security/upgrade patches to customer on top of the existing release they have. There is a separate submission area for each released Windchill version called customer patch code submission area. Once developer submits relevant bug fix code to that area we have to build a temp patch against the Released version. We are using a jardiff mechanism to create the delta between released version and the code submitted to that temp patch.
Responsibilities
Implement patch creation process for various PTC products.
Automate Customer patch creation process using Ant and XML.

JSPs are Precompiled as a web application at packaging time to check their syntax during the JSP compilation process. This gives you confidence that the JSPs at least compile without syntax errors before you deploy your webapp. This avoids a situation where you have deployed your web application to the production server(s) only to find out later that the JSP(s) had a syntax error that was found by the first user requesting that page.
The Windchill approach to precompiling JSPs is as follows:
Compile all Java source to ensure that the JSPs' Java dependencies are built and available
Use the Jasper Engine to convert the JSPs from their HTML format into Java classes (in Java source format) of servlet type
Using javac, compile the newly generated Java source into its .class byte code format

Rsync is an open source program that can be used to synchronize two directories located on two different machines. Rsync in a windchill process context implies that the files/directories for a particular build are transferred to remote sites' application storing repository (called masterpack). Rsync scripts refer to wrappers written around the open source rsync program that enable automatic rsync of masterpack builds between all sites. Rsync is configured in a star topology. All builds get sync'd to a central server (i.e. Needham) and then to the remote site. e.g. A build distributed in Blaine (BLN), reaches Pune (PUN) via Needham(NDM) i.e. BLN -> NDM -> PUN.
