Installation

Steps:

1. The scheduler will be automatically available if the case-engine profile is added to the list of spring active profiles in the bootstrap.properties. More information on how to configure the application using Spring Profiles can be found here: External application configuration with Spring Profiles.
2. Add the application-case-engine.properties file in the configuration location if it does not yet exist. This properties file is added in the 
   spring.config.additional-location
   directory when using the Blueriq installer.
3. Run the provided scripts for creating the quartz tables in the database: msssql.sql or oracle.sql. The scripts are located in the release zip in \Runtime\Java\Webapp\DBScripts\blueriq-case-engine-scheduler-quartz
4. Define quartz database connection in the application-externaldatasources.properties file.

Configuration

Quartz is configured using a set of properties. Quartz uses a job store in order to persist jobs details, triggers and other job related information. We support two types of job stores:

• Memory (default) ^{for demo's and standalone development}
• Database ^recommended 

Memory (default)

By default memory mode is enabled which should be used only for demos and standalone development. For recommended settings please check the database settings. For memory the following setting should be set in the application-case-engine.properties.

spring.quartz.job-store-type = memory

Database

Scripts to create the required database content are provided for the following databases:

• SQL Server
• Oracle

Generate the Quartz Database

Specify database properties

To enable the JDBC Connection the externaldatasources profile must enabled and the following properties have to be used:

spring.quartz.job-store-type = jdbc
spring.quartz.properties.org.quartz.jobStore.tablePrefix = QRTZ_

# For MSSQL, use a driver delegate
#spring.quartz.properties.org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.MSSQLDelegate

JDBCJobStore’s “table prefix” property is a string equal to the prefix given to Quartz’s tables that were created in your database. You can have multiple sets of Quartz’s tables within the same database if they use different table prefixes.

Specify connection

The datasource can be specified directly using the external datasources, or via JNDI.

JDBC connection

Enable the externaldatasources profile and add the following properties to the application-externaldatasources.properties:

blueriq.datasource.scheduler-quartz.driverClassName = com.microsoft.sqlserver.jdbc.SQLServerDriver
blueriq.dataSource.scheduler-quartz.url = jdbc:sqlserver://<server_url>:<port>;databaseName=<database_name>;instance=<instance_name>
blueriq.datasource.scheduler-quartz.username = <user>
blueriq.datasource.scheduler-quartz.password = <password>

blueriq.datasource.scheduler-quartz.driverClassName = oracle.jdbc.driver.OracleDriver
blueriq.dataSource.scheduler-quartz.url = jdbc:oracle:thin:@<server_url>:<port>:xe
blueriq.datasource.scheduler-quartz.username = <user>
blueriq.datasource.scheduler-quartz.password = <password>

JNDI connection

To enable JNDI Connection enable the application-jndidatasources.properties profile and add the following properties to the application-jndidatasources.properties:

// JBoss Example provided that the jndi name is set to java:jboss/jdbc/quartzdb
blueriq.datasource.scheduler-quartz.jndiName = java:jboss/jdbc/quartzdb

// Tomcat Example provided that the jndi name is set to jdbc/quartzdb
blueriq.datasource.scheduler-quartz.jndiName = java:/comp/env/jdbc/quartzdb

Thread Pool

When the database is configured, we recommend to also configure the thread pool. Each DCM project gets its own trigger. It is recommended to have a thread per DCM project. For example if you have 3 DCM projects you should set the threadCount to 3.

Please check that the threadCount does not exceed the number of available database connections (or connections in the database connection pool). The quartz documentation suggests the following: provided that the database allows X connections, then the threadCount must be set to X - 3.

Below are the default thread Pool properties:

spring.quartz.properties.org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
spring.quartz.properties.org.quartz.threadPool.threadCount = 2

Clustering

There are many configuration properties for clustering, see the Quartz documentation. To enable clustering, specify at least these properties:

spring.quartz.properties.org.quartz.jobStore.isClustered = true
spring.quartz.properties.org.quartz.scheduler.instanceName = MyClusteredScheduler
# Have Quartz generate an instanceId for each node in the cluster
spring.quartz.properties.org.quartz.scheduler.instanceId = AUTO
