Quartz Integration On Oracle Weblogic

Quartz Integration On Oracle Weblogic

1. Pre-requisite for quartz integration

Pre-requisite to integrate quartz on WebLogic are as follows

1. Oracle WebLogic installed

2. Oracle/Database installed for connectivity

3. Application classes/jars, database connectivity drivers ( ojdbc14.jar )

4. JDK 1.6.0.3 or above

2. Starting Quartz on Oracle Weblogic (Windows Platform)

Before starting the application server, perform the following steps

1.  Place the following jars/files in following directory

Installed Drive\Oracle\Middleware\user_projects\domains\testdomain\lib

�    org.jar

�    custom.jar

�    com.jar

�    jta-1_1-classes.jar

�    quartz-weblogic-2.1.5.jar

�    QuartzScheduler.cfg

2.  Place the log4j.xml file in following directory

Installed Drive\Oracle\Middleware\user_projects\domains\testdomain

Note : "testdomain" in above path is the domain created while installing weblogic

3. Configuration changes

�    QuartzScheduler.cfg

FileLogHeartbeats=Y ScreenLogShowHeartBeats=Y scriptFile=Framewrk/subs/json.lib,Framewrk/subs/filter.js,Framewrk/subs/da te.lib,Framewrk/common/FuncUtils.jds,Framewrk/common/dbUtils.jds,Frame wrk/common/DBSchema.js,Framewrk/subs/common.lib,Framewrk/main.jds orgMsgLogPath=C:/log serverPath=E:/Weblogic/weblogicwar/mfx_4_1_0_retail.war jndiName=mfx_4_1_0_retail_xa

FileLogHeartbeats : Log the quartz instance ScreenLogShowHeartBeats : On weblogic console show the quartz log scriptFile : Applications files to be loaded in quartz instance orgMsgLogPath : System path to log quartz info

serverPath : Path of application

jndiName : JNDI name used to connect to the deployed application.

Note : jndiName is the name of the data source created to connect to the application

4.  Changes in application web.xml file

Path : Path to WAR\WAR Name\WEB-INF

Add the following tag and details to web.xml file inside the <web-app> tag

<servlet>

<servlet-name>QuartzInitializer</servlet-name>

<servlet-class>org.quartz.ee.servlet.QuartzInitializerServlet</servlet-cla

ss>

<init-param>

aram-name>shutdown-on-unload</param-name>

aram-value>true</param-value>

</init-param>

<init-param>

aram-name>start-scheduler-on-load</param-name>

aram-value>true</param-value>

</init-param>

<init-param>

aram-name>config-file</param-name>

aram-value>quartz.properties</param-value>

</init-param>

oad-on-startup>1</load-on-startup>

</servlet>

Note : If these changes are not made in the web.xml file of the application, the quartz scheduler will not run for the deployed application

5.  Place the "quartz.properties" file in deployed application

Path : Path to WAR\WAR Name\WEB-INF

�    Quartz.properties

#=============================================================

# Configure Main Scheduler Properties

#=============================================================

org.quartz.scheduler.instanceName = QuartzScheduler org.quartz.scheduler.rmi.export = false org.quartz.scheduler.rmi.proxy = false org.quartz.scheduler.xaTransacted = false

#org.quartz.scheduler.instanceId = AUTO

#=============================================================

# Configure ThreadPool

#=============================================================

org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool org.quartz.threadPool.threadCount = 100 org.quartz.threadPool.threadPriority = 4

org.quartz.scheduler.logger = schedLogger org.quartz.logger.schedLogger.class = org.quartz.impl.Log4jLogger

#=============================================================

# Configure JobStore

#=============================================================

org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreCMT

org.quartz.jobStore.driverDelegateClass =

org.quartz.impl.jdbcjobstore.StdJDBCDelegate

org.quartz.jobStore.dataSource = mfx_4_1_0_retail_xa

org.quartz.jobStore.tablePrefix = QRTZ_

#=============================================================

# Configure Datasources

#============================================================= org.quartz.dataSource.mfx_4_1_0_retail_xa.jndiURL = mfx_4_1_0_retail_xa org.quartz.jobStore.nonManagedTXDataSource = mfx_4_1_0_retail_xa org.quartz.jobStore.maxMisfiresToHandleAtATime=60000

org.quartz.plugin.triggHistory.class =

\org.quartz.plugins.history.LoggingTriggerHistoryPlugin

org.quartz.plugin.triggHistory.triggerFiredMessage = \Trigger \{1\}.\{0\} fired job \{6\}.\{5\} at: \{4, date, HH:mm:ss MM/dd/yyyy}

org.quartz.plugin.triggHistory.triggerCompleteMessage = \ Trigger \{1\}.\{0\}

completed firing job \{6\}.\{5\} at \{4, date, HH:mm:ss MM/dd/yyyy\}.

Configuration changes to be made

�    Configure JobStore Section

Properties

org.quartz.jobStore.dataSource - Name of the data source created in weblogic to connect to the database

�    Configure Datasources Section

Properties

org.quartz.dataSource.mfx_4_1_0_retail_xa.jndiURL = mfx_4_1_0_retail_xa org.quartz.jobStore.nonManagedTXDataSource = mfx_4_1_0_retail_xa

mfx_4_1_0_retail_xa in above properties is the data source name

6.  Weblogic environment settings changes for quartz integration

�    Open the "setDomainEnv.cmd" file and add the following code snippet

Path : Installed

Drive\Oracle\Middleware\user_projects\domains\testdomain\bin

Snippet :

Search for "LOG4J_CONFIG_FILE%" in the file and before that line add the following snippet

�    set

LOG4J_CONFIG_FILE="E:/Oracle/Middleware/user_projects/domains/c

redence/log4j.xml"

This is the path to log4j.xml file that we placed in weblogic above in the guide.

7.  Once the above changes are done restart the weblogic server and you will see

following messages flashing on weblogic console indicating the quartz status
