New

  • Various new and changed topics document new support for internal flash memory exploitation. The coupling facility can now migrate objects out to storage-class memory (SCM) when the number of objects exceeds a calculated threshold, then it can fetch the objects back into main CF storage when requested.
  • Various new and changed topics document support for the new XCF Note Pad Service function. The XCF Note Pad Service is a new application programming interface that allows programs to manipulate notes in an XCF note pad. A note pad is an abstraction layered on top of the existing coupling facility list structure interfaces. You can use the new IXCNOTE macro to manipulate data in a coupling facility list structure, provided the note pad abstraction meets the needs of the application.
