Mainframe Operations

The Polk County property tax collection and apportionment systems run on an IBM Mainframe. The system also supports the Public Works Weeds application, certain functions for the Auditor's office, and Voucher System processing for the Family Enrichment Center, General Assistance, and Veteran's Affairs.

The mainframe system processes approximately 20,000 online transactions per day, which includes both production business processes and development.

Production processes occur Monday through Friday, from 5:00 to 10:00pm. An automated Job Scheduling software package is in place to reduce staffing needs.

The Operations group is responsible for the following:

  • Systems programming
  • Configuration of new 3rd party packages
  • Disk maintenance
  • Nightly production schedule
  • RAC-F Security
  • Configuration of automatic job scheduler
  • Distribution of print and other media
  • Offsite storage
  • Backups and restores
