How to analyze Oracle Solaris OS crash dump


In this topic I will provide information how to generate Oracle Solaris OS crash dump report using Solaris Crash Analyzer Tool.


Here I will provide information how to find out root cause of Oracle Solaris OS crash dump reboot or hung up.

If your system properly installed and configured according EIS (Enterprise Installation Standard) – then you dump

device must be configured as separated raw disk and must have size at least more than installed physical memory

on the server. In most system the dump device is the same swap device. If your system is frame based and installed memory

is more than 320GB ( SAS disk) – then you need assign to the system dedicated dump device no less thane size of physical

memory. Otherwise – in time when system will go to crash dump, the memory state will fully dumped to the dump device

and you will lose last memory snapshot to make root cause analyze of system crash.

DNS 2010 v9.7.2 64bit version for Solaris 10 Ultar-sparc T2+ edition


There new build version of BIND v9 DNS server special edition for Sun UltraSparc T1/T2+ CPU platform

New Features

  • Zones may be dynamically added and removed with the “rndc addzone” and “rndc delzone” commands. These dynamically added zones are written to a per-view configuration file. Do not rely on the configuration file name nor contents as this will change in a future release. This is an experimental feature at this time.
  • Added new “filter-aaaa-on-v4” access control list to select which IPv4 clients have AAAA record filtering applied.
  • A new command “rndc secroots” was added to dump a combined summary of the currently managed keys combined with statically configured trust anchors.
  • Added support to load new keys into managed zones without signing immediately with "rndc loadkeys". Added support to link keys with "dnssec-keygen -S" and "dnssec-settime -S".

DNS BIND v9.7 Release for Sun Solaris 10 x86_x64 bit


BIND 9.7.0 includes a number of changes from BIND 9.6 and earlier releases. Most are intended to simplify DNSSEC configuration.

New features include:

  • Fully automatic signing of zones by "named"
  • Simplified configuration of DNSSEC Lookaside Validation (DLV).
  • Simplified configuration of Dynamic DNS, using the "ddns-confgen" command line tool or the "local" update-policy option. (As a side effect, this also makes it easier to configure automatic zone re-signing.)
  • New named option "attach-cache" that allows multiple views to share a single cache.
  • DNS rebinding attack prevention.
  • New default values for dnssec-keygen parameters.
  • Support for RFC 5011 automated trust anchor maintenance (see README.rfc5011 for additional details).
  • Smart signing: simplified tools for zone signing and key maintenance.
  • The "statistics-channels" option is now available on Windows.
  • A new DNSSEC-aware libdns API for use by non-BIND9 applications (see README.libdns for details).
  • On some platforms, named and other binaries can now print out a stack backtrace on assertion failure, to aid in debugging.
  • A "tools only" installation mode on Windows, which only installs dig, host, nslookup and nsupdate.
  • Improved PKCS#11 support, including Keyper support and explicit OpenSSL engine selection (see README.pkcs11 for additional details).
