Article: Using Oracle Database 11g Release 2 Result Cache in an Oracle RAC Environment
Learn about the advantages of this feature for databases in which your data does not change very frequently, such as in a data warehouse or reporting database environment.
We have setup a new Solaris 10 SPARC on an old Sun T5220 box to move some really old apps on ancient hardware and Solaris versions before they die. These are all slated to be replaced but we are seeing issues with some of the older boxes and want to move them.

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.
