RDCSIZE - Size of Buffer for the Natural Data Collector

This Natural profile parameter specifies the size of the Natural Data Collector buffer, which is used by the SYSRDC utility and the Profiler utility, and it controls the trace recording function of the Natural Data Collector.

Possible settings 2 - 128 Buffer size (in KB).

  • To activate the Natural Data Collector (without trace recording), you specify RDCSIZE=2.

  • To also activate the trace recording, set RDCSIZE to a setting greater than 2.

  • The Profiler utility needs a buffer size greater than 2 to activate the trace recording.

  • Automatic activation of the trace recording function during session initialization takes place only if profile parameter RDC or macro NTRDC is set to ON.

  • If the requested space is not available, the Natural Data Collector cannot be used.

0 Deactivates the Natural Data Collector.
Default setting 0  
Dynamic specification yes  
Specification within session no  

Notes:

  1. As an alternative, you can use the equivalent Natural subparameter SIZE of profile parameter RDC or macro NTRDC.
  2. Alternatively, you can specify the RDCSIZE value in Natural profile parameter DS or macro NTDS to specify the size of the buffer.
  3. For further information, see Activating the Natural Data Collector in the SYSRDC Utility documentation.
