File Descriptors and User Connections

The number of user connections used by SAP ASE cannot exceed the number of file descriptors available to SAP ASE on the operating system.

When configuring user connections on SAP ASE, the system administrator should take into account the number of file descriptors available per process. Although most of the open file descriptors are available for user connections, a few are used by SAP ASE for opening files and devices.
