WORK HISTORY:

Systems Engineer

Confidential

Responsibilities:

• I was one of two systems programmers to bring in and set up a new zBC12 mainframe. We upgraded this a few years later to a z13 2965-M01. The mainframe is connected via FICON to a VMAX3/100k for DASD and two DLMs attached to a Data Domain for tape.
• We sync this data in a mirrored environment to the same physical machine setup at an alternate site.
• We staged disasters and recovered with verified data from the Applications teams within our scheduled times. We recently installed GDDR and went through various testing exercises with the vendor. We are also looking at VFI and expect to eliminate ABARS and HSM with these products.
• An outside vendor performed a security audit that included mainframe security. There were voluminous amounts of necessary RACF security definitions not in place and I was assigned to implement the updates. I rolled them out in controlled groups and tested in warning mode when first implemented to test for legitimate exceptions or other fallout.
• Another project that resulted from the security audit was the implementation of the Intrusion Detection System. After installing IDS, I created automation utilizing OPS/MVS to intercept the messages as they come out on the console and trigger batch jobs to send email reports to Cybersecurity, Security, and Systems Programmers.
• My first project at Southwest Gas was to convert their IP Printway to the LRS product suite. I detailed all existing IP Printway definitions and converted them to VPS and DRS configurations. It was not a straight-forward conversion as the definitions differ greatly.
• The next project was to upgrade the Tivoli Workload Scheduler. The current version was 8.3 and required two upgrades to get caught up. It was necessary to upgrade first to version 8.6 and then to version 9.3. I did another upgrade a few years later to version 9.5. I also worked with the Linux and Windows teams regarding the installation of the Agents required to manage workloads on their environments from TWS on the mainframe.
• I installed and maintained the following products at this site, all of which are current. I have installed multiple versions of several products in the list. z/OS ( Confidential - versions 1.13, 2.0, and 2.2)

Software Engineer

Confidential

Responsibilities:

• Due to my performance & tuning experience, I was brought in by Confidential to develop a variety of Java Performance monitors for the JVM running under Unix System Services (USS) in the z/OS environment.
• These products provided Java performance information on applications such as WebSphere and MQ Series.
• The z/OS product was designed to show the impact on Java applications from applications running outside of the JVM (DB2, CICS, Batch, etc.) as well as the impact of other Java applications running inside of the JVM. Setting up the development environment included the installation of z/OS, CICS, DB2, WebSphere and MQ Series, RACF security administration, etc
• When I started, they were running off of a Hercules-type emulator but I had to arrange for us to lease an Confidential from Confidential to perform the work.
• During my tenure at Confidential, I developed a variety of Java Performance monitors for the JVM running under Unix System Services (USS) in the OS/390 & z/OS environments.
• These products provided performance information on applications such as WebSphere and MQ Series. My primary responsibilities were to provide research, coding, testing, product enhancement, maintenance & fixes and level 2 support for Customer Service, with additional responsibilities to assist in Project Management, Education, Technical Documentation, Quality Assurance, Product Packaging and Marketing.
• I was also responsible for the Confidential mainframe environment and was the primary support for all OEM software (z/OS, CICS, MQ, WebSphere, etc.) and testing applications (i.e., Trade2 & Trade3). I was responsible for coding/upgrading all related usermods.
• All of the Confidential software was installed using SMP/E.
• I developed project plans for all projects using Microsoft Project including timelines and work assignments (for myself and others).
• I kept abreast of fixes (PTF's and APARs) from Confidential and coordinated the testing and implementation of these fixes with the in-house staff.
• They were put into production only after I received validation of reliability from the QA team.
• I also interacted similarly with Independent Software Vendors regarding upgrades for their OEM software.
• I also chaired the Change Management meetings and administered all mainframe issues.
• Migration of all software, upgrades, and fixes into the production environment were coordinated with all other technical groups via Change Management meetings after verification of the desired affect and stability.
• I provided initial drafts of product documentation, followed by iterations of edits before approving the final documentation.
• I documented all processes (software installs/upgrades, operational procedures, help-desk problem resolution procedures, etc.).
• I trained the in-house staff in the use of the various mainframe software products (most were not very mainframe savvy), and how to use the canned processes that I provided for maintenance or customization of these software products.
• I trained the operations and help desk staff in problem determination and resolution procedures.

Systems Programmer

Responsibilities:

• My services were retained in this multi-platform environment (OS/390, AIX, Windows, UNIX, MS SQL Server) to upgrade all mainframe software to be Y2k compliant and to provide enhancements to legacy applications before beginning a project to move all applications off of the mainframe while continuing mainframe support.
• I was one of five systems programmers when I started. That was quickly whittled down to just me. I developed project plans for all projects using Microsoft Project including timelines and work assignments (for myself and others).
• I also developed client and server applications to move data to and from the mainframe.
• My own specific contributions are detailed below.
• Mainframe - I upgraded all of the mainframe operating system (OS/390) and subsystem software as well as all of the Independent Software Vendor (or 3rd party) software products.
• All of the Confidential software was installed using SMP/E.
• I evaluated new and installed software for possible implementation or elimination. I was responsible for all mainframe issues; OS/390, CICS, VTAM, TCPIP, DASD Management, RACF Security management, user exits and user mods (for MVS, JES2, CICS, etc.), problem isolation and resolution, Focus Change Management, Enterprise Output Manager (EOM), performance tuning, Disaster Recovery, mainframe network connections and hardware. I monitored and applied necessary maintenance (PTFs and APARs) from Confidential as well as patches from 3rd party software vendors and coordinated all implementations with the in-house staff. Migration of all software, upgrades, and fixes into the production environment were coordinated with all other technical groups via Change Management meetings after verification of the desired affect and stability.
• I documented all processes (software installs/upgrades, operational procedures, help-desk problem resolution procedures, etc.).
• I trained the operations staff in IPL procedures and the use of job scheduling software.
• I trained the operations and help desk staff in problem determination and resolution procedures.
• I also educated the application programming staff in efficient system designs, program designs, proper coding techniques, debugging techniques, and Cobol and CICS language restrictions, as well as providing technical support for systems services and problem resolution.
• Some of the hardware oriented MVS and VTAM tasks that I have performed include configuring Open Systems Adapters (OSA-2), VTAM/NCP, 3174 controllers, 3099 multiplexers, Sysplex Timer, Hardware Configuration Definition (HCD), RAMAC Virtual Storage Array (RVA - like RAID or SHARK), implementing the Storage Management System (DFSMS & DFHSM), writing TCPIP Server and Client programs for the mainframe, setting up Sysplex and IPL procedures for the individual LPARS via the Hardware Management Console (HMC), configuring Confidential 's 2216 N-ways connector (MAS Network Utility), setting up VTAM generic resources, and setting up FTP processes between the mainframe and other computers. Since we were down to one CPC, I removed the Sysplex Timer and set the HCM clock as the timer. I also assisted the network group in problem resolution between the mainframe, Cisco routers & hubs, and other computers.
• Move applications off of mainframe - I set up interfaces to the many other computers (TCPIP, APPN, etc) that the various doctor groups owned and managed projects for the replacement of the mainframe systems. Data conversion programs, file transfer and import programs and scripts were required.
• As applications were removed from the mainframe, I consolidated the workload and reduced the number of LPARs.
• The offloaded and converted applications encompassed all of the Patient Accounting Systems and the Clinical Systems.
• The other applications were replaced with purchased software packages. When the move was completed, I backed up and cleared all of the disks and shut down the mainframe.
