CLI allocates a single request buffer per session. The allocation takes place when the session is first established.

DBCHCL automatically:
  • Expands the buffer if it is too small to hold the request being prepared.
  • Shrinks the buffer if Request Buffer Length is less than Current Request Buffer Length.
