# 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.
