CHAPTER 3 Configuring the Operating System

Configuration Guide 35

For Linux

The number of file descriptors per process is limited to 10,000. You can set the

number of file descriptors using

ulimit.

For Sun Solaris

For Sun Solaris, you can set both soft and hard limits for file descriptors. The

soft limit can be increased up to the hard limit by the user, but the hard limit

can be increased only by someone with “root” permissions. The soft limit

determines the number of open file descriptors available to an Adaptive Server

engine. The limit is 10,000.

Although most of the open file descriptors are available for user connections,

a few are used by Adaptive Server engines for opening files and devices.

See the System Administration Guide for additional information on user

connections.
