SPARC: Application interface to Remote Shared Memory on clusters

If you develop applications that extend the use of a Sun^TM Cluster environment, you can benefit from this interface. Using the new Remote Shared Memory API, you can program your applications to lower the latency for message passing over high-speed cluster interconnects. Such cluster-aware applications can significantly reduce the time that is required to respond to events in a clustered configuration. You must have Sun Cluster 3.0 installed. Also, you need expertise to modify existing applications to exploit the new interface.

The librsm(3LIB) man pages and the section (3RSM) "Section 3: Extended Library Functions" man pages include references to RSM.

Dynamic Host Configuration Protocol (DHCP)

The Dynamic Host Configuration Protocol (DHCP) service enables host systems to receive IP addresses and network configuration information at boot time from a network server. Before this release, DHCP configuration data could only be stored in text files or NIS+. In this release, data access in the Solaris DHCP service has been redesigned to use a modular framework. Solaris DHCP provides an API that enables you to write shared objects to support any data storage facility for storing DHCP data.  

The Solaris DHCP Service Developer's Guide provides an overview of the data access framework that is used by Solaris DHCP, general guidelines for developers, and a listing of the API functions you use to write a module to support a new data store.

For further information, see the Solaris DHCP Service Developer's Guide.

A vectored sendfile system call: sendfilev()

A vectored sendfile system call, sendfilev() enables better performance for sending out data from application buffers or files. For example, in web performance, a web server can construct an HTTP response (header, data, and trailer as well as SSI server-side includes) in a single system call. This feature provides optimal performance with NCA, because it enables the return of multiple chunks, which might come from various files for the response.

For further information, see the man page sendfilev(2).

Sun WBEM Software Developer's Toolkit (SDK)

Web-Based Enterprise Management (WBEM) includes standards for web-based management of systems, networks, and devices on multiple platforms. The Sun WBEM Software Developer's Toolkit (SDK) enables software developers to create standards-based applications that manage resources in the Solaris operating environment. Developers can also use this toolkit to write providers, programs that communicate with managed resources to access data. The Sun WBEM SDK includes Client Application Programming Interfaces (APIs) for describing and managing resources in Common Information Model (CIM), and Provider APIs for getting and setting dynamic data on the managed resource. The Sun WBEM SDK also provides CIM WorkShop, a Java application for creating and viewing the managed resources on a system, and a set of example WBEM client and provider programs.  

For more information, see the Sun WBEM SDK Developer's Guide.
