What's New in the Solaris 9 Operating Environment

Diagnostic and Availability Enhancements

Feature Description
`coreadm` Command The `coreadm` command provides flexible core file-naming conventions and better core file retention.
Examining Core Files with `proc` Tools The `proc` tools are utilities that can manipulate features of the `/proc` file system. Some of the `proc` tools have been enhanced to examine process core files as well as live processes.
Improved Device Configuration `(devfsadm)` The `devfsadm` command provides an improved mechanism for managing the special device files in the `/dev` and `/devices` directories, including support for dynamic reconfiguration events.
Improved System Error Messages The system boot and error message format now provides a numeric identifier, module name, and timestamp to messages that are generated by the `syslog`(1M) logging facility. In addition, messages that were previously lost after a system panic and reboot are now saved.
Modular Debugger `(mdb)` `mdb` is a new extensible utility for low-level debugging and editing of the live operating system, operating system crash dumps, user processes, user process core dumps, and object files.
Remote Console Messaging This release includes the `consadm` command, which enables you to select a serial device as an auxiliary (or remote) console for troubleshooting remote system problems.
TCP/IP Internal Trace Support TCP/IP now provides internal trace support by logging TCP communications when a connection is terminated by a reset (RST) packet.

Feature Description

coreadm Command

The coreadm command provides flexible core file-naming conventions and better core file retention.

Examining Core Files with proc Tools

The proc tools are utilities that can manipulate features of the /proc file system. Some of the proc tools have been enhanced to examine process core files as well as live processes.

Improved Device Configuration (devfsadm)

The devfsadm command provides an improved mechanism for managing the special device files in the /dev and /devices directories, including support for dynamic reconfiguration events.

Improved System Error Messages

The system boot and error message format now provides a numeric identifier, module name, and timestamp to messages that are generated by the syslog(1M) logging facility. In addition, messages that were previously lost after a system panic and reboot are now saved.

Modular Debugger (mdb)

mdb is a new extensible utility for low-level debugging and editing of the live operating system, operating system crash dumps, user processes, user process core dumps, and object files.

Remote Console Messaging

This release includes the consadm command, which enables you to select a serial device as an auxiliary (or remote) console for troubleshooting remote system problems.

TCP/IP Internal Trace Support

TCP/IP now provides internal trace support by logging TCP communications when a connection is terminated by a reset (RST) packet.
