Solaris 7 Software Developer Supplement

Chapter 1 What's New at a Glance

This chapter highlights new features added to the SolarisTM 7 operating environment in the 11/99, 8/99, 5/99, and 3/99 releases.

Table 1-1 Solaris 7 Features


First Released in . . . 


Installation (These features are described in the Solaris 7 Installation Collection.)

AnswerBook2 ab2cd script updates


Updates to the ab2cd script enable users to read AnswerBook2TM documentation directly from the Solaris Documentation CD.

DNS configuration during system identification 


Prior Solaris releases only allowed the configuration of a machine as a NIS or NIS+ client. With the Solaris 7 5/99 release, systems can be configured by the system identification utilities to be DNS clients. 

Product Registry 


The Solaris Product Registry is a tool to manage installed software. It enables you to:

  • View a list of installed and registered software and some software attributes

  • Uninstall software

  • Browse for and launch an installer

Patch Analyzer 


The Patch Analyzer performs an analysis on your system to determine which (if any) patches will be removed or downgraded by upgrading from a Solaris 7 operating environment to the Solaris 7 11/99 operating environment. This analysis can be performed either at upgrade time or while the system is in production mode.  

(Intel Platform Edition only) Added support for PAE mode 


With the release of Pentium Pro, Intel introduced a mode called Physical Address Extension (PAE) on its advanced processors. PAE mode enables you to run multiple instances of databases and memory-intensive applications, and to support large numbers of online users on your machine.  

This feature is described in the Solaris 7 11/99 Release Notes.

System and Network Administration (These features are described in the Solaris 7 System Administration Supplement.)

Universal Disk Format (UDF) file system 


The UDF file system is the industry-standard format for storing information on optical media called digital versatile disc or digital video disc (DVD) that is both readable and re-writable. 

Digital versatile disk or digital video disk  


This release supports digital versatile disc or digital video disc (DVD) that is both readable and re-writable. 

(Intel Platform Edition only) PCI hot-plugging with cfgadm command


The cfgadm command is updated to provide PCI hot-plugging for supported PCI controllers on x86 systems.

Improved device configuration (devfsadm)


The devfsadm command manages the special device files in the /dev and /devices directories and is updated to detect device configuration changes by any reconfiguration event.

(SPARC Platform Edition only) Inter-Domain Network (IDN)  


Inter-Domain Network (IDN) supports high-speed networking between Dynamic System Domains (DSDs). This enables DSDs to communicate with each other using standard networking interfaces, such as TCP/IP, without the use of cabling or special hardware. 

See your hardware manufacturer's documentation for information about IDN and to see if IDN supports your server. 



The coreadm command provides improved core file management for Solaris system administrators.

Enhanced SCSI hot-plugging with the cfgadm


The cfgadm command now supports SCSI hot-plugging for supported SCSI hardware.

Migrating to BIND 8.1 


This section updates Bind 8.1 in the Solaris Naming Setup and Configuration Guide and the Solaris Naming Administration Guide.

AnswerBook2 server software updates 


Updates in AnswerBook2 version 1.4.1 server software improve navigation and performance. 

Remote console 


New system console features, including the consadm command, enable system administrators and service providers to remotely troubleshoot systems by dialing in to a system using a modem connected to one of the serial ports and to redirect console messages to the auxiliary device.

(SPARCTM Platform Edition only) Dynamic reconfiguration


Dynamic reconfiguration allows the service provider to add or remove and replace hot-pluggable system boards in a running system, eliminating the time lost in rebooting. For more information, see your hardware manufacturer's documentation. 

Deferred access time updates on UFS file systems 


New mount options, dfratime and nodfratime, enable and disable deferred access time updates on UFS file systems.

Improved system boot and error message format 


The system boot and error message format is improved by adding a numeric identifier, module name, and time stamp to messages generated by the syslog logging facility.

(SPARC Platform Edition only) Improved handling of cron jobs on suspended systems


When you use Power ManagementTM software to suspend and resume a system, there is now a check on whether cron jobs were scheduled during the time the system was suspended. If there were, the first instance of a cron job is performed when the system resumes. (This improvement was available in the Solaris 7 release and first documented in the Solaris 7 3/99 release.)


(SPARC Platform Edition) Dynamic reconfiguration support for SCSI HBA drivers 


In this release, dynamic reconfiguration (DR) support has been updated for SCSI devices. 

See your hardware manufacturer's documentation to see if your server supports DR. 

PCI hot-plugging 


PCI hot-plugging is updated to include information on writing device drivers for x86 servers.  

8-bit visual support 


The 8-bit visual shared library enables device drivers with only 24-bit hardware to display 8-bit visual applications. 

Solaris 7 64-bit Developer's Guide updates


This is a list of updates in the Solaris 7 64-bit Developer's Guide.

Updated DDI interfaces for cluster-aware device drivers 


This overview introduces the concept of device classes and the necessary interface modifications and additions for device driver writers. 

Java Development Kit  

JDK 1.1.7_08 


The JDKTM 1.1.7_08 includes:

  • Enhanced Eurocurrency support

  • High-performance Just In Time compiler

A JavaTM Runtime Environment (JRE) corresponding to the latest version of the JDK is available for download from the Web.

Java 2 SDK 1.2.1_03 


The Java 2 SDK 1.2.1_03 is the first Solaris release of Java technology based on Java 2. It includes:

  • Substantially increased scalability and performance

  • Enhanced memory management system

  • High-performing, scalable Java Virtual Machine (JVM)

  • Fast Java thread synchronization

  • Enhanced diagnostics with the heap inspection tool, which finds memory leaks in programs

  • Optimizing Just In Time compiler

Desktop User (These features are described in the Solaris 7 User Supplement.)

Personal Digital Assistant (PDA) synchronization 


PDA synchronization enables data to be synchronized from Sun applications, such as Calendar Manager, with data in a similar application on your PDA. Also, applications and databases can be installed from your workstation or server to your PDA. 

NetscapeTMapplication launcher


The Desktop-Apps folder window has four new icons:

  • Netscape

  • Netscape Composer

  • Netscape Mail

  • Netscape News
