The number of file descriptors per process is determined by the operating system parameter open_max. The default value of open_max is 32767. Adaptive Server can use a maximum of 2000 file descriptors per engine, regardless of the value of open_max. For more information on setting open_max, see the AIX operating system documentation.
To obtain the current value of the open_max parameter, use the Korn or Bourne shell ulimit command:
ulimit -n
