Scheduler job using mule

1. Scheduler Job using Mule
A sample mule flow demonstrating how
to create a schedule job in few minutes.

2. Concept Brief:
• Mule provides Quartz scheduler Connector
• Quartz connector to be used a in-bound
endpoint
• Use cron Expression or MMC option for
defining scheduled time.
• Job name should not have special character
like _ etc
• Repeat count can be defined.

3. cron expression
A cron expression is a string comprised of 6 or 7 fields separated by white space. Fields can
contain any of the allowed values, along with various combinations of the allowed special characters for
that field. The fields are as follows:
• Field Name Mandatory Allowed Values Allowed Special Characters
• Seconds YES 0-59 , - * /
• Minutes YES 0-59 , - * /
• Hours YES 0-23 , - * /
• Day of month YES 1-31 , - * ? / L W
• Month YES 1-12 or JAN-DEC , - * /
• Day of week YES 1-7 or SUN-SAT , - * ? / L #
• Year NO empty, 1970-2099 , - * /
cron expressions can be as simple as this: * * * * ? *
• or more complex, like this: 0/5 14,18,3-39,52 * ? JAN,MAR,SEP MON-FRI 2002-2010
