Hibernate transactions had to be started for each HTTP request from an anonymous or
authenticated user, which in turn required a new database connection from the connection
pool (an expensive operation if it is not required for the request). The fix enables a new
option, "lazyStartOfHibernateTransaction", which is set in
gatein.ear/02portal.war/WEB-INF/conf/organization/picketlink-idm/picketlink-idm-config.xml.

<para>If the value is set to true, the Hibernate transaction is started only when
required, and not for every request. The default value is false for
backwards-compatibility.

Key: GTNPORTAL-2463
URL: https://issues.jboss.org/browse/GTNPORTAL-2463
Project: GateIn Portal
Issue Type: Enhancement
Security Level: Public(Everyone can see)
Components: Identity integration
Affects Versions: 3.2.0-GA
Reporter: Nicolas Filotto
Assignee: Boleslaw Dawidowicz
Labels: performance
Attachments: LAZY-OPEN-TX-IDM.patch
The component {{PicketLinkIDMOrganizationServiceImpl}} has been defined as a
{{ComponentRequestLifecycle}} to be able to scope an "identity transaction" to
the life time of the request. However depending on the page we try to access, it could be
useless to open a tx in case the organization service is not even accessed which can have
a dramatic impact on performances for nothing especially when we use hibernate because
when we open a tx with hibernate, it does a JDBC call to switch to non auto commit mode.
