NAME
Data::Session::Driver::Oracle - A persistent session manager
Synopsis
See Data::Session for details.
Description
Data::Session::Driver::Oracle allows Data::Session to store sessions via DBD::Oracle.
To use this module do both of these:
- o Specify a driver of type Oracle, as Data::Session -> new(type => 'driver:Oracle ...')
- o Specify a database handle as Data::Session -> new(dbh => $dbh) or a data source as Data::Session -> new(data_source => $string)
Case-sensitive Options
See "Case-sensitive Options" in Data::Session for important information.
Method: new()
Creates a new object of type Data::Session::Driver::Oracle.
new() takes a hash of key/value pairs, some of which might mandatory. Further, some combinations might be mandatory.
The keys are listed here in alphabetical order.
They are lower-case because they are (also) method names, meaning they can be called to set or get the value at any time.
- o data_col_name => $string
-
Specifes the name of the column in the sessions table which holds the session data.
This key is normally passed in as Data::Session -> new(data_col_name => $string).
Default: 'a_session'.
This key is optional.
- o data_source => $string
-
Specifies the data source (as used by DBI -> connect($data_source, $username, $password, $attr) ) to obtain a database handle.
This key is normally passed in as Data::Session -> new(data_source => $string).
Default: ''.
This key is optional, as long as a value is supplied for 'dbh'.
- o data_source_attr => $string
-
Specifies the attributes (as used by DBI -> connect($data_source, $username, $password, $data_source_attr) ) to obtain a database handle.
This key is normally passed in as Data::Session -> new(data_source_attr => $string).
Default: {AutoCommit => 1, PrintError => 0, RaiseError => 1}.
This key is optional.
- o dbh => $dbh
-
Specifies the database handle to use to access the sessions table.
This key is normally passed in as Data::Session -> new(dbh => $dbh).
If not specified, this module will use the values of these keys to obtain a database handle:
Default: ''.
This key is optional.
- o host => $string
-
Not used.
- o id_col_name => $string
-
Specifes the name of the column in the sessions table which holds the session id.
This key is normally passed in as Data::Session -> new(id_col_name => $string).
Default: 'id'.
This key is optional.
- o password => $string
-
Specifies the password (as used by DBI -> connect($data_source, $username, $password, $data_source_attr) ) to obtain a database handle.
This key is normally passed in as Data::Session -> new(password => $string).
Default: ''.
This key is optional.
- o port => $string
-
Not used.
- o socket => $string
-
Not used.
- o table_name => $string
-
Specifes the name of the sessions table.
This key is normally passed in as Data::Session -> new(table_name => $string).
Default: 'sessions'.
This key is optional.
- o username => $string
-
Specifies the username (as used by DBI -> connect($data_source, $username, $password, $data_source_attr) ) to obtain a database handle.
This key is normally passed in as Data::Session -> new(username => $string).
Default: ''.
This key is optional.
- o verbose => $integer
-
Print to STDERR more or less information.
Typical values are 0, 1 and 2.
This key is normally passed in as Data::Session -> new(verbose => $integer).
This key is optional.
Method: remove($id)
Deletes from storage the session identified by $id, or dies if it can't.
Returns 1.
Method: retrieve($id)
Retrieve from storage the session identified by $id, or dies if it can't.
Returns the session.
This is a frozen session. This value must be thawed by calling the appropriate serialization driver's thaw() method.
Data::Session calls the right thaw() automatically.
Method: store($id => $data)
Writes to storage the session identified by $id, together with its data $data, or dies if it can't.
Returns 1.
Method: traverse()
Retrieves all ids from the sessions table, and for each id calls the supplied subroutine with the id as the only parameter.
$dbh -> selectall_arrayref is used, and the table is not locked.
Returns 1.
