Hi all,
We dont have access to aix source code and i have a doubt.
The flag SC_NO_RESERVE, is it got to do anything with the failover?
If the flag is set the paths are going to failed state. If flag is not set everything comes up fine after failover.
Thanks in advance for helping

Hey, all!
Why is the "human readable" flag changing the behavior of du? And while I'm at it, can you make du only look at files, not directories. I often find myself wanting to find the largest file(s) in a dir or vol. Using 'find' itself, it seems you have to at least be able to guess the size of... (2 Replies)

Tree::Simple::Visitor::GetAllDescendents(3pm) User Contributed Perl Documentation Tree::Simple::Visitor::GetAllDescendents(3pm)NAME
Tree::Simple::Visitor::GetAllDescendents - A Visitor for fetching all the descendents of a Tree::Simple object
SYNOPSIS
use Tree::Simple::Visitor::GetAllDescendents;
# create an instance of our visitor
my $visitor = Tree::Simple::Visitor::GetAllDescendents->new();
# pass the visitor to a Tree::Simple object
$tree->accept($visitor);
# you can also get the descendents
# back as an array of node values
my @descendents = $visitor->getDescendents();
# for more complex node objects, you can specify
# a node filter which will be used to extract the
# information desired from each node
$visitor->setNodeFilter(sub {
my ($t) = @_;
return $t->getNodeValue()->description();
});
DESCRIPTION
Given a Tree::Simple instance this Visitor will return all the descendents recursively on down the hierarchy.
METHODS
new There are no arguments to the constructor the object will be in its default state. You can use the "setNodeFilter" method to customize
its behavior.
setTraversalMethod ($visitor)
By default we will use Tree::Simple's built in depth-first (pre-order) traverse method. If however, you desire the descendents to be
returned in a different ordering, this can be accomplished using a different traversal method, you can supply a $visitor object
implementing that traversal type to this method (See Tree::Simple::Visitor::BreadthFirstTraversal,
Tree::Simple::Visitor::PreOrderTraversal and Tree::Simple::Visitor::PostOrderTraversal).
setNodeFilter ($filter_function)
This method accepts a CODE reference as its $filter_function argument and throws an exception if it is not a code reference. This code
reference is used to filter the tree nodes as they are collected. This can be used to customize output, or to gather specific
information from a more complex tree node. The filter function should accept a single argument, which is the current Tree::Simple
object.
visit ($tree)
This is the method that is used by Tree::Simple's "accept" method. It can also be used on its own, it requires the $tree argument to be
a Tree::Simple object (or derived from a Tree::Simple object), and will throw and exception otherwise.
getAllDescendents
This method will give back and array of descendents in depth-first order (pre-order) or in the order specified by the
"setTraversalMethod". If called in scalar context it will give an array reference, in list context it will return a regular array. This
method is the same as calling "getResults".
BUGS
None that I am aware of. Of course, if you find a bug, let me know, and I will be sure to fix it.
CODE COVERAGE
See the CODE COVERAGE section in Tree::Simple::VisitorFactory for more inforamtion.
SEE ALSO
These Visitor classes are all subclasses of Tree::Simple::Visitor, which can be found in the Tree::Simple module, you should refer to that
module for more information.
