PROFESSIONAL EXPERIENCE:

Confidential, Algonquin, IL

Mainframe Storage Contractor

Responsibilities:

  • Cleaning up HSM and DFSMS environments as there are issues.
  • Have 10 LPARS under 1 DFHSM environment and they want to split it to 4 environments. Ran HSM expirebv. It freed up over 400000 backup datasets and made over 1000 tapes available for recycle. Recycled the tapes.
  • Apparently no recycle process developed as recycled over another 2500 tapes.
  • Audited the HSM MCDS and received over 9000 errors. Cleaned up errors.
  • Both BCDS and OCDS also had errors which were cleaned up
  • Set up DB2 data base logical backups outside of DB2 but recommended they get a DB2 product to back them up. As if you restore DB2 databases outside of DB2, there is major issue because DB2 has it’s own internal catalog.
  • Redesigned DFSMS as no management class was being set as no ACS Routine for managemet class. Wrote management class ACS routine and then copied different storage classes to force back into the ACS Routines and set Management Class.
  • Cleanup of catalogs as a lot of entries pointing to volumes that do not exist and entries pointing to volumes but the data is not there.
  • Micro Focus has no catalog product and no way to forward recover a catalog.
  • Micro Focus has HSM journaling turned off so no way to forward recover an HSM control dataset if lost.
  • After all my clean up notified Micro Focus that this on going process and if ignored will wind up with the same mess.
  • Parallel Sysplex with 10 LPARS and 1 monoplex.
  • Contract ended as Micro Focus hired some one locally in Utah
