.IX Title "Apache::Session::Store::Informix 3pm"
.TH Apache::Session::Store::Informix 3pm "2020-09-20" "perl v5.30.3" "User Contributed Perl Documentation"
.\" For nroff, turn off justification.  Always turn off hyphenation; it makes
.\" way too many mistakes in technical documents.
.if n .ad l
.nh
.SH "NAME"
Apache::Session::Store::Informix \- Store persistent data in a Informix database
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
.Vb 1
\& use Apache::Session::Store::Informix;
\&
\& my $store = new Apache::Session::Store::Informix;
\&
\& $store\->insert($ref);
\& $store\->update($ref);
\& $store\->materialize($ref);
\& $store\->remove($ref);
.Ve
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Apache::Session::Store::Informix fulfills the storage interface of
Apache::Session. Session data is stored in a Informix database.
.SH "SCHEMA"
.IX Header "SCHEMA"
To use this module, you will need at least these columns in a table 
called 'sessions':
.PP
.Vb 2
\& id char(32)     # or however long your session IDs are.
\& a_session lvarchar
.Ve
.PP
To create this schema, you can execute this command using the sqlplus program:
.PP
.Vb 4
\& CREATE TABLE sessions (
\&    id char(32) not null primary key,
\&    a_session lvarchar
\& );
.Ve
.PP
If you use some other command, ensure that there is a unique index on the
table's id column.
.SH "CONFIGURATION"
.IX Header "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.
.PP
Example:
.PP
.Vb 5
\& tie %hash, \*(AqApache::Session::Informix\*(Aq, $id, {
\&     DataSource => \*(Aqdbi:Informix:database\*(Aq,
\&     UserName   => \*(Aqdatabase_user\*(Aq,
\&     Password   => \*(AqK00l\*(Aq
\& };
.Ve
.PP
Instead, you may pass in an already-opened \s-1DBI\s0 handle to your database.
.PP
.Vb 3
\& tie %hash, \*(AqApache::Session::Informix\*(Aq, $id, {
\&     Handle => $dbh
\& };
.Ve
.PP
The last option is LongReadLen, which specifies the maximum size of the session
object.  If not supplied, the default maximum size is 8 \s-1KB.\s0

.IX Header "AUTHOR"

on the original for Oracle.
