5+ years experience providing 24/7 on-call production

balancing, etc.

PROJECTS

WebSphere Automated Publishing Program - Developed an

application using JMX API to automate EAR publish. It

could install, update and restart EARs, restart clusters

and send email notifications to users about application

publish status.

Automated Cluster/Jvm setup - Developed JACL/Jython

scripts to automatically setup clusters/jvms with 3M

specific properties. Automated scripts to setup

datasources, URL providers, namespace bindings, JMS

listener ports, connection factories, destinations, etc.

Application Availability Status Website - Developed

website to display application related data -

Application Server/Cluster details, Datasource

information, URL providers, Namespace bindings, etc.

Used Perl/JACL scripts to pull data and refresh

information on a daily basis for over 300 applications

and 1000 jvm instances.

Plugin Manipulation - Plugin merge script to

automatically merge WebSphere plugins from different

cells during migration so a common webserver could act

as frontend for applications hosted on different

environments. Also split plugins to setup virtual

clusters to disperse traffic among anonymous,

authenticated and jvms serving blob content (pdfs,

images, etc).

Siteminder TAI chaining - Implemented a custom TAI

module and chained with Siteminder TAI so getRemoteUser

calls would return a generic guest account for anonymous

users.

Middleware capacity planning for environments hosting

3rd party applications such as Filenet P8, Maximo, etc.

End-to-end SSL implementation (Webserver -> Middleware

-> Database) for PCI compliance

Jvm Status Reports - Three years worth of data in csv

format for application server restarts, out of memory

and heapdump count etc to facilitate creation of pivot

tables and charts for capacity reviews.
