Optimized Read Process for Nonrelational Data Sources

Optimized Read Process for Nonrelational Data Sources

PowerExchange optimizes the read process for nonrelational database (NRDB) and file sources on z/OS. This optimization applies to SQL queries that contain a WHERE clause.
The following data sources support the NRDB optimized read process:
  • Adabas
  • Datacom
  • IDMS
  • IMS (DL/1 and ODBA)


We’d like to hear from you!
