Most of these systems have near real-time performance requirements so performance tuning/troubleshooting skills were exercised routinely. I repeatedly used my programming experience to develop Perl, Korn shell and C scripts/programs to automate the monitoring and maintenance of our distributed systems from a central location. System and database monitoring was done with a combination of Candle and Big Brother. I developed several Big Brother plug-ins for specialized monitoring such as Oracle, MQ/Series, SNA and print queues. My applications development experience and kernel-level OS knowledge provide me with excellent troubleshooting and analysis skills required for efficient and accurate problem diagnosis and resolution. I was the sole MQ/Series middleware administrator and performed a pivotal role in its implementation during our Forward Warehousing project. MQ/Series messaging was important for accurate and effective communication between our production facilities and warehouses. My network / TCP/IP troubleshooting skills were also crucial in timely diagnosis and resolution of related issues. I'm very familiar with common Unix stack tools such as tcpdump, netstat, ping, traceroute and spray. The servers were subjected to routine internal and external security audits so I demonstrated initiative by designing and developing a database driven web tool for monitoring, querying and reporting user account and activity data from all Unix servers. A common set of customized Perl scripts executing on each server wrote data directly to a centralized MySQL database on a Linux server. I'm also very familiar with the Postgres RDBMS.
