Applying the patches in liferay

-

We are using EE version of liferay and we found a bug and reported to liferay. They have given patch to solve this issue. This patch will be ZIP file.

Copy the ZIP file and paste in patches folder of  this location  "<liferay-tomcat>/tomcat/patching-tool/patches".

Sometimes our patching tool will contain the lower version comapared to provided version. So we need to upgrade to latest version.

version number can know by using the following command as

In Linux
./patching-tool.sh info

In Windows
patching-tool info

After executing this command look into the line of  patching-version in the  output console.

Note : All of these commands should be execute from the "<liferay-tomcat>/tomcat/patching-tool".

In Order to install the patch execute the following command

In Linux
./patching-tool.sh install

In Windows
patching-tool install

After applying the patch we can see the console installation completed successfully.

Sometimes your installed patch may contain collision, to list out the collisions use

In Linux
./patching-tool.sh list-collisions

In Windows
patching-tool list-collisions


Also sometimes it is required to update the plugins, so use

In Linux
./patching-tool.sh update-plugins

In Windows
patching-tool update-plugins


Thats it now we have applied the patch.

Viewing the SQL Query in liferay : debugging the SQL Query in Hibernate

-
Sometimes we have to know SQL query hiting in DB to retrieve the list. Suppose When we are writing the DynamicQuery , Some times we have to know SQL query it is generating to hit DB. 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.

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 to see hibernate ses
