Tech Specialist

Responsibilities:

  • Install middleware tier products - WebSphere Application Server, Process Server, Portal, and MQ as well as Tuxedo, IHS, Introscope, Siteminder, UDB.
  • Keep abreast of product updates for fixpacks and major releases which may address security issues, product bugs, improve performance or extend EOL (End-Of-Life) support.
  • Maintain product fixpacks and major update installations. This includes impact analysis, package automation scripting and coordination of updates to non-production and production environments and application testing and signoff.
  • Maintain and install product interim fixes to address defects. Coordinate the rollout of these interim fixes to non-production and production environments, including application testing and signoff.
  • Responsible for Tier III (Application) configuration once middleware tier product installation is complete
  • While Tier III configuration is application specific and highly variable, some common configurations include:
  • Datasource setup and configuration.
  • Scripting post-installation deployment configurations. This includes web client bindings, timeout values, shared library settings and SCA module component settings.
  • JVM arguments and custom properties.
  • MQ and JMS resources.
  • Work Managers.
  • Thread and WebContainer Pools.
  • Dynamic Caching and WebContainer Caching.
  • Driver and adapter installation and setup.
  • Web instance creation and setup.
  • Webserver instance and plugin configuration.
  • Write and maintain deployment scripts for new products or applications. Configure existing deployment scripts for new domains or applications where applicable. Conduct initial application deployment
  • Request additional resources where necessary from Hosting Services. Examples include F5/Big-IP, DNS or Firewall configurations, Memory and CPU allocations and OS settings and upgrades.
  • EBC acts as L3 Support for each application and product in the domain they support
  • While all support issues are first handled by PMIT Support Ops(L2), common issues that are escalated to EBC are:
  • Production and Non-Production slowdowns and outages.
  • Deployment problems. Includes an application or resource being misconfigured or missing from the code build, resource (LPAR, OS, server, etc.) constraints causing deployment failures or script problems.
  • Product bugs - either introduced with new application functionality or a product defect encountered during runtime.
  • Runtime application failures which are not code related.
  • General L2 escalation and knowledge sharing. When the L2 team encounters an issue that is new or that they are unfamiliar with it is escalated to EBC. In addition to working the issue, if EBC determines it is typically something that could be handled by L2 then additional details, including identification and resolution steps, are documented and communicated to the L2 team for future reference.
  • Support for all major monthly releases, weekly releases and Emergency Change’s.
  • Collect IBM “must gather” information for the PMIT Performance Engineering Team or IBM. This includes generating of heap-dumps, thread-dumps and system dumps.
  • Analyze IBM “must gather” information via IBM Support Assistant.
  • Perform regular, ongoing analysis of Production and Non-Production JVM memory logs.
  • Participate in weekly application and product tuning meetings.
  • Provide input on analysis conducted by the Performance Engineers and Performance Test team
  • Provide input on recommended tuning changes.
  • Perform ad hoc review and tuning of Non-Production environments in response to developer or business feedback.
  • As a takeaway, coordinate any configuration changes that will increase application performance or more appropriately tune an environment.
  • Working with ATS Engineers or lead developers during project inception; provide input on expected middleware products and versions (including any new fixpacks, product enhancements, drivers or adapters necessary in order to support the application) and assist with impact analysis.
  • Provide detailed task lists and summaries to Project Managers for EBC related tasks including work estimates in order to drive the project delivery schedule.
  • Attend project meetings, update project managers on environment build and delivery progress.
  • Coordinate product or application rollouts with project managers and environment planners.
  • Client Interaction.
  • Onsite-Offshore co-ordination.
