Apache::Session::Store::Sybase fulfills the storage interface of Apache::Session. Session data is stored in a Sybase database.
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
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).
This module was based on Apache::Session::Store::Oracle which was written by Jeffrey William Baker <[email protected]>; it was modified by Chris Winters <[email protected]> to work with Apache::Session 1.5+ with changes from earlier version of Apache::Session::DBI::Sybase from Mark Landry <[email protected]>.
