Using VTS (Virtual Table Share)

The DataKinetics VTS product augments the tableBASE core product by providing the capability to share table data. Using tableBASE, regions load tables into a local table space region (TSR). Many regions loading tables into their TSRs simultaneously can hamper system performance, especially if the regions are using the same tables. After augmenting the core product with VTS, many regions can access the same data from a single shared TSR; a virtual table share (VTS-TSR). This can:

  • improve system performance both at IPL and during run-time
  • reduce system resource usage including system memory, CPU cycles and I/O

tableBASE VTS concepts are introduced in VTS (Virtual Table Share), with more detail under tableSPACE Region.

This section describes how you can use tableBASE VTS to:

  • Improve system performance
  • Reduce system resource usage
  • Improve data integrity
  • Implement message queueing
