Solaris 2.6 Support

This version of Solaris CAT is the last release to support Solaris 2.6.
If you have systems running Solaris 2.6, please note that that release

New Commands


When a type is specified on the command line, it can include an optional

the modules in the core are searched in order for the specified type.

This new command allows specifying a list of modules to be searched prior
to scanning the module. Modules are specified using a colon-separated

It can also be used to display the current list, or to clear it.

qlcfc fplog|ssfcplog

This new command dumps the qlc logs. If the fplog subcommand is specified,
the fp_logq is displayed. If the ssfcplog subcommand is specified, the
ssfcp_logq is displayed.


scat_version has been added so that the release/version of the

scat --scat_explore [-v] [-a] [-d dest] [unix.N] [vmcore.]N


-v Verbose Mode: The command will print messages highlighting what it's doing.
-a Auto Mode: The command does not prompt for input from the user as it runs.
