  • Assisted in the setup and migration to a new DR location (2022)

  • Installed CA7 V12.1 with Datacom V15.1, and followed Broadcom/CA procedures to migrate from CA7 V11.3

  • Assisted in the installation and migration to three new z15 processors (2019), with one at a remote DR location, and a smaller z14 business class processor

  • Assisted in the installation of z/OS 2.3, and the successful migration from z/OS 2.1 into production on all LPARs

  • ServerPac installation of MQ 9.1 Long Term Support Release (LTSR), and migration from MQ 8.0

  • Upgrade of EMC Disk in 2015, using the z/OS Migrator tool and the use of REXX to build the necessary Jobs. REXX was used to analyze and cross reference UCB addresses to Symm addresses, as well as build the necessary z/OS Migrator Jobs. Migration to new disk was performed in one day for production disk, without any need of IPLs

  • Performed migration from diverse physical and virtual tape to new TS7720 clusters in 2012, in a three cluster grid. Used REXX, utilities, and Assembler code written to successfully migrate over 350,000 tapes.Two years later upgraded all three TS7720 clusters in the grid, and used REXX and IBM supplied LIBRARY COPYRFSH command to again migrate over 350,000 tapes. Chose not to use IBMTOOLS. Extensive use of Bulk Volume Information Retrieval (BVIR), and REXX to manage the TS7720 clusters. Used Assembler code to read three sources of input, to include: BVIR input, Catalog Search Interface (CSI) of associated VOLCATs, and CA1 Tape Management Catalog (TMC). This code helped to better manage the tape libraries.

  • Assisted with the upgrade to an EMC DLM8500. Used the DLM batch utility for CP503 reporting of tapes, along with an Assembler program to read the CA1 TMC, DLM CP503 report, and CSI of OAM VOLCATs, all to validate Scratch and Private status across all three. Analysis resulted in identification of tapes that could be scratched in the DLM with DLMSCR utility, and a large reclaim of space in the DLM8500.
