NAME

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

SYNOPSIS

 use Apache::Session::Store::Sybase;
 my $store = new Apache::Session::Store::MySQL;
 $store->insert( $ref );
 $store->update( $ref );
 $store->materialize( $ref );
 $store->remove( $ref );

DESCRIPTION

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

SCHEMA

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

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

To create this schema, you can execute this command using the isql or sqsh programs:

 CREATE TABLE sessions (
    id         CHAR(32) not null primary key,
    a_session  TEXT
 )
 go

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

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
Password

Example:

 tie %hash, 'Apache::Session::Sybase', $id, {
     DataSource => 'dbi:Sybase:database=db;server=server',
     UserName   => 'database_user',
     Password   => 'K00l',
     Commit     => 1,
 };

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

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

Additional arguments you can pass to the backing store are:

Commit - whether we should commit any changes; if you pass in an already-open database handle that has AutoCommit set to a true value, you do not need to set this. If you let Apache::Session::Store::Sybase create your database, handle, you must set this to a true value, otherwise, your changes will not be saved
textsize - the value we should pass to the 'set textsize ' command that sets the max size of the IMAGE field. Default is 32K (at least in Sybase ASE 11.9.2).
