o/s file descriptors indicates the maximum per-process number of file descriptors configured for your operating system. This parameter is read-only and cannot be configured through Adaptive Server.

Many operating systems allow you to configure the number of file descriptors available per process. See your operating system documentation for further information on this.

The number of file descriptors available for Adaptive Server connections, which will be less than the value of o/s file descriptors, is stored in the variable @@max_connections. For more information on the number of file descriptors available for connections, see “Upper limit to the maximum number of user connections”.
