z/OS Security Server RACF Callable Services
SA23-2293-00

  1. This service is intended only for use by the MVS™ BCP.
  2. The key is meaningful only when the following subpools are used:
    • 129–132
    • 227–231
    • 241
  3. The following user security information is propagated from the parent address space to the child address space:
    • Controlled status
    • Keep-controlled indicators
    • Saved messages
      Note: Only a subset of this information is copied during the first call to R_fork. A second call may be necessary. RACF® reason code 4 indicates that there is additional security information related to the parent address space that should be propagated to the child address space. If a reason code 4 is received when a flag value of 0 was passed, R_fork should be called again with a flag value of 2 specified. If a reason code 4 is received when a flag value of 1 was passed, R_fork should be called again with a flag value of 3 specified.
  4. This service uses task-level support when z/OS UNIX has indicated in the task's ACEE that this is a task-level process.
