Get an introduction to using Oracle Data Integrator, Java-based middleware that uses the database to perform set-based data integration tasks in an SOA.
Hi,
I have a log file that gets updated every second. Currently the size has grown to 20+ GB. I need to have a command/script, that will try to get the actual size of the file and will remove 50% of the data that are in the log file. I don't mind removing the data as the size has grown to huge... (8 Replies)

Data::Grove(3pm) User Contributed Perl Documentation Data::Grove(3pm)NAME
Data::Grove -- support for deeply nested structures
SYNOPSIS
use Data::Grove;
$object = MyPackage->new;
package MyPackage;
@ISA = qw{Data::Grove};
DESCRIPTION
"Data::Grove" provides support for deeply nested tree or graph structures. "Data::Grove" is intended primarily for Perl module authors
writing modules with many types or classes of objects that need to be manipulated and extended in a consistent and flexible way.
"Data::Grove" is best used by creating a core set of ``data'' classes and then incrementally adding functionality to the core data classes
by using ``extension'' modules. One reason for this design is so that the data classes can be swapped out and the extension modules can
work with new data sources. For example, these other data sources could be disk-based, network-based or built on top of a relational
database.
Two extension modules that come with "Data::Grove" are "Data::Grove::Parent" and "Data::Grove::Visitor". "Data::Grove::Parent" adds a
`"Parent"' property to grove objects and implements a `"root"' method to grove objects to return the root node of the tree from anywhere in
the tree and a `"rootpath"' method to return a list of nodes between the root node and ``this'' node. "Data::Grove::Visitor" adds callback
methods `"accept"' and `"accept_name"' that call your handler or receiver module back by object type name or the object's name.
"Data::Grove" objects do not contain parent references, Perl garbage collection will delete them when no longer referenced and sub-
structures can be shared among several structures. "Data::Grove::Parent" is used to create temporary objects with parent pointers.
Properties of data classes are accessed directly using Perl's hash functions (i.e. `"$object->{Property}"'). Extension modules may also
define properties that they support or use, for example Data::Grove::Parent adds `"Parent"' and `"Raw"' properties and Visitor depends on
`"Name"' and `"Content"' properties.
See the module "XML::Grove" for an example implementation of "Data::Grove".
METHODS
new( PROPERTIES )
Return a new object blessed into the SubClass, with the given properties. PROPERTIES may either be a list of key/value pairs, a single
hash containing key/value pairs, or an existing "Data::Grove" object. If an existing "Data::Grove" is passed to `"new()"', a shallow
copy of that object will be returned. A shallow copy means that you are returned a new object, but all of the objects underneath still
refer to the original objects.
