Database connection pool C3po configuration in liferay

-
In Liferay, default connection pool is c3p0 configured using portal-ext.properties. Liferay Portal also supports the database connection pool configuration through the Application Server.

Liferay can access the Application Server level data source using JNDI. It is recommended to use the JNDI-based database connection pool configuration.

Add the following property in the portal-ext.properties.

jdbc.default.jndi.name=jdbc/LiferayPool

Open the server.xml in the <liferay-home>/tomcat/conf folder

Locate the Resource tag and add the following properties.

<Resource
auth="Container"
description="Portal DB Connection"
driverClass="com.mysql.jdbc.Driver"
maxPoolSize="75"
minPoolSize="10"
acquireIncrement="5"
name="jdbc/LiferayPool"
user="<MySQL Database User Name>"
password="<MySQL Password>"
factory="org.apache.naming.factory.BeanFactory"
type="com.mchange.v2.c3p0.ComboPooledDataSource"
jdbcUrl="jdbc:mysql://<MySQL Database Server IP>:3306/lportal?useUnicode=true&amp;characterEncoding=UTF 8&amp;useFastDateParsing=false"/>

We should fill the appropriate values in the properties like user , password etc with your values.

 Then we should add these 2 libraries in the tomcat/lib folder. We can get these lib's in the <liferay-home>/tomcat/webapps/ROOT/WEB-INF/lib folder.

1.c3p0.jar
2.mchange-commons-java.jar.

 Thats it Restart the server. We have configured the liferay with c3po connection pool using JNDI

In Liferay we can exceute the background task asynchrously. The Background Task framework allows the developers to create and manage any kind of tasks that need to be run in a separated thread without the need of knowing anything about JAVA threading or concurrency Here the code ThemeDisplay themeDisplay = (ThemeDisplay) request.getAttribute(WebKeys.THEME_DISPLAY); Map taskContextMap = null; String taskName = null; String servletContextNames [] = new String[1] ; Portlet portlet = PortletLocalServiceUtil.getPortletById(request.getAttribute(WebKeys.PORTLET_ID).toString()); servletContextNames[0] = portlet.getContextName(); try { BackgroundTaskLocalServiceUtil.addBackgroundTask(themeDisplay.getUserId(), themeDisplay.getScopeGroupId(), taskName, servletContextNames,TestBackgroundTaskExecutor.class, taskContextMap,new ServiceContext()); } catch (PortalException e) { e.printStackTrace(); } catch (SystemException e) { e.printStackTrace(); } ...

So generally it is useful when we are debugging the Query it is generated. In hibernate we used the write the property in XML file as hibernate.show.sql to view the query. In Liferay also we can also set the below property to true in the portal-ext.properties to view the SQL query at the console. hibernate.show_sql=true. By adding the above property it will just reterive the parameters. What if we want to display the parameters. Add the below properties in log4j.properties it will display the paramters also. # logs the SQL statements #log4j.logger.org.hibernate.SQL=debug # Logs the JDBC parameters passed to a query #log4j.logger.org.hibernate.type=trace In Liferay log4j is located in the below location tomcat-7.0.42\webapps\ROOT\WEB-INF\classes Also we want t...
