What's New in the Solaris 9 Operating Environment

File System Enhancements

Feature Description
Universal Disk Format (UDF) File System The UDF file system, the industry-standard format for storing information on optical media technology, is supported in this Solaris release. You can use the UDF file system to exchange data on the following components when they contain a UDF file system: CD-ROMs Disks and diskettes Digital versatile disc or digital video disc (DVD) - DVD-ROM on supported platforms
NFS Server Logging NFS server logging enables an NFS server to provide a record of file operations that are performed on its file systems. This feature is particularly useful for sites that make anonymous FTP archives available to NFS and WebNFS^TM clients.
IA: Extended Memory (XMEM) Support XMEM support provides a mechanism that enables a single 32-bit process to efficiently allocate and manage more than 4 Gbytes of physical memory. The XMEM feature is implemented as a file system (`xmemfs`) that system administrators can mount and use to reserve memory for applications.
WebNFS JavaBeans Component The WebNFS JavaBeans^TM component contains an XFileChooser class that extends the JFileChooser graphical component of the Java 2 API. This bean can be used by any Java 2 application that needs to display a file chooser to enable users to select a file for input (open) or output (save). By using XFileChooser, an application can access a file on a local disk or on an NFS server through the use of NFS URL naming.
Deferred Access Time Updates on UFS File Systems Two new mount options, `dfratime` and `nodfratime`, enable and disable deferred access time updates on UFS file systems. When writing access time updates for the file system are enabled, they can be deferred until the disk is accessed for tasks other than updating access times.

Deferred Access Time Updates on UFS File Systems

Two new mount options, dfratime and nodfratime, enable and disable deferred access time updates on UFS file systems. When writing access time updates for the file system are enabled, they can be deferred until the disk is accessed for tasks other than updating access times.
