This always needs obtain new DB connection from connection pool, which is quite expensive operation. +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> -FIX: There is fix available in underlying component Picketlink IDM, which added possibility to start Hibernate transaction lazily only for case when it's really needed. It's adding new option "lazyStartOfHibernateTransaction" into Picketlink IDM configuration file. Value true means that Hibernate transaction will be started lazily only when needed. Value false is starting transaction non-lazily during each request (current behaviour) +<programlisting> - + <option> -RESULT: In configuration file gatein.ear/02portal.war/WEB-INF/conf/organization/picketlink-idm/picketlink-idm-config.xml is new option added:</para> + <name>lazyStartOfHibernateTransaction</name> - <programlisting><option> + <value>false</value> - <name>lazyStartOfHibernateTransaction</name> + </option> - <value>false</value> +</programlisting> - </option></programlisting> +<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.- -<para>We can see that default value is false, so behaviour is same like before (because of backward compatibility and avoiding of risk). - -But for customers, who have problem with performance and DB connection is critical for them, it would be good to switch this option to "true". -- This message is automatically generated by JIRA.
