Purpose
While using JavaMelody to monitor JIRA, it may be required to provide the database connection using JNDI. This page describes how to connect JIRA to PostgreSQL using JNDI parameters.
Please note that the JNDI parameters shown below such as maxActive are from Tomcat 7. In Tomcat 8+ , some of these have changed. For example, maxActive has been updated to maxTotal. For help with Tomcat 8 and above, please refer to the KB on JNDI database connection needs an upgrade to Jira 7.x or above.

Open $JIRA_INSTALL/conf/server.xml. Within the
Contextelement, configure aResourceelement oftype="javax.sql.DataSource"as in the example below. Note that you need to copy only the first<Resource ... >from the following snippet:server.xml - <Resource ...><Context path="/jira" docBase="${catalina.home}/atlassian-jira" reloadable="false" useHttpOnly="true"> <!-- The following Resource is for JNDI --> <Resource name="jdbc/jirads" auth="Container" type="javax.sql.DataSource" username="database_user" password="database_password" driverClassName="org.postgresql.Driver" url="jdbc:postgresql://localhost:5432/jira_database" connectionProperties="" maxActive="100" maxWait="10000" validationQuery="select version();" removeAbandoned="true" logAbandoned="true" testWhileIdle="true" timeBetweenEvictionRunsMillis="60000" minEvictableIdleTimeMillis="300000" /> <Resource name="UserTransaction" auth="Container" type="javax.transaction.UserTransaction" factory="org.objectweb.jotm.UserTransactionFactory" jotm.timeout="60"/> <Manager pathname=""/> </Context>
Configure the $JIRA_HOME/dbconfig.xml as follows:
dbconfig.xml<jira-database-config> <name>defaultDS</name> <delegator-name>default</delegator-name> <database-type>postgres72</database-type> <schema-name>public</schema-name> <jndi-datasource> <jndi-name>java:comp/env/jdbc/jirads</jndi-name> </jndi-datasource> </jira-database-config>
