Fast Path buffer uses in a DBCTL environment

Fast Path buffers are used to hold various types of Fast Path data.

Fast Path buffers are used to hold:
  • Update information such as inserted SDEP segments.
  • Referenced DEDB CIs from the root addressable part and the sequential dependent part.
  • Updated DEDB CIs from the root addressable part.
  • SDEP segments that have gone through sync point. The segments are collected in the current SDEP segment buffer. One buffer allocated for each area defined with the SDEP segment type exists. This allocation takes place at area open time.
