Most common version of UNIX on production systems
I am new to UNIX (about a year) and learning as fast as I can. I am an instructor teaching UNIX and have two labs with Ultra 10 333 MHz, Sun Blade 1000 1 GHz, Blade 100, and Two Enterprise 250 Servers. We are currently teaching our classes using the Solaris 2.10 OS, downloaded in May 2006, I am not sure of the exact release. I have heard that version 10 is rarely used in production systems and that most businesses are using 2.8. If this is the case, should we be teaching students on the OS that they are most likely to be using when they are hired? I am familiar enough with Solaris 2.9 to see some of the differences between 2.9 and 2.10, but completely unfamiliar with Solaris 2.8.

exacct::object::item
Exacct::Object::Item(3PERL) Perl Library Functions Exacct::Object::Item(3PERL)
NAME
Exacct::Object::Item - exacct item manipulation
SYNOPSIS
use Sun::Solaris::Exacct::Object;
my $ea_item = Sun::Solaris::Exacct::Object::Item->new(
&EXT_UINT64 | &EXC_DEFAULT | &EXD_PROC_PID, $$);
DESCRIPTION
This module is used for manipulating libexacct(3LIB) data Items. A libexacct Item is represented as an opaque reference blessed into the
Sun::Solaris::Exacct::Object::Item class, which is a subclass of the Sun::Solaris::Exacct::Object class. The underlying libexacct data
types are mapped onto Perl types as follows:
libexacct type Perl internal type
EXT_UINT8 IV (integer)
EXT_UINT16 IV (integer)
EXT_UINT32 IV (integer)
EXT_UINT64 IV (integer)
EXT_DOUBLE NV (double)
EXT_STRING PV (string)
EXT_RAW PV (string)
EXT_EXACCT_OBJECT Sun::Solaris::Exacct::Object subclass
Constants
None.
Functions
None.
Class methods
Class methods include those inherited from the Sun::Solaris::Exacct::Object base class, plus the following:
new($catalog, $value) This method creates and returns a new Sun::Solaris::Exacct::Object::Item. The catalog tag can be either an integer
or a Sun::Solaris::Exacct::Catalog. This catalog tag controls the conversion of the Perl value to the correspond-
ing Perl exacct data type as described in the table above. If the catalog tag has a type field of
EXT_EXACCT_OBJECT, the value must be a reference to either an Item or a Group object and the passed object is
recursively copied and stored inside the new Item. Because the returned Item is constant, it is impossible, for
example, to create an Item representing CPU seconds and subsequently modify its value or change its catalog value.
This behavior is intended to prevent mismatches between the catalog tag and the data value.
Object methods
Object methods are those inherited from the Sun::Solaris::Exacct::Object.
Exports
None.
