NAME

       Apache::Session::Store::Oracle - Store persistent data in a Oracle database

SYNOPSIS

	use Apache::Session::Store::Oracle;

	my $store = new Apache::Session::Store::Oracle;

	$store->insert($ref);
	$store->update($ref);
	$store->materialize($ref);
	$store->remove($ref);

DESCRIPTION

       Apache::Session::Store::Oracle fulfills the storage interface of Apache::Session. Session data is stored in a Oracle database.

SCHEMA

       To use this module, you will need at least these columns in a table called 'sessions':

	id varchar2(32)     # or however long your session IDs are.
	a_session long

       To create this schema, you can execute this command using the sqlplus program:

	CREATE TABLE sessions (
	   id varchar2(32) not null primary key,
	   a_session long
	);

       If you use some other command, ensure that there is a unique index on the table's id column.

CONFIGURATION

       The module must know what datasource, username, and password to use when connecting to the database.  These values can be set using the
       options hash (see Apache::Session documentation).  The options are DataSource, UserName, and Password.

       Example:

	tie %hash, 'Apache::Session::Oracle', $id, {
	    DataSource => 'dbi:Oracle:database',
	    UserName   => 'database_user',
	    Password   => 'K00l'
	};

       Instead, you may pass in an already-opened DBI handle to your database.

	tie %hash, 'Apache::Session::Oracle', $id, {
	    Handle => $dbh
	};

       The last option is LongReadLen, which specifies the maximum size of the session object.	If not supplied, the default maximum size is 8 KB.
