OIC gen3 - Integration patterns and Define schedules

Integration patterns:

1. Application : Real time call or data feed from the subscriber.
2. Schedule: Runs at specific dates and times defined in a schedule. Mainly used for bulk or batch integration or file processing.
3. Event: starts when an event is published. It is like EDN or even driven Architecture or publish subscribe model.

Creating a schedule: 

There are two ways, we can create or define a schedule of a schuduled integration.

1. On the design canvas , click the ellipsis on schedule node and edit schedule definition.
2. Add a schedule on the integrations page before or after the integration has been activated.

Schedule types:

1. Simple schedule

• We can define only once - hour minutes, days months, weeks
• We can also define recurring schedule - hourly, minutely, daily, monthly, weekly
• Frequency can not be less then 10 mins.
• We can set specific timezone, add a time window to run or never expire mode by default.

1. Advanced schedule or iCal expression

• We use calender expression 
• Frequncy can be set minutely(<10 mins).
• We can also define multiple schedule frequencies together using &.

Examples:

Example 1: This example runs on the 1st, 10th and 15th days of the month at 5:15am, 10:15am , 3:15pm and 8:15 pm.

FREQ=MONTHLY;

BYMONTHDAY=1,10,15;

BYHOUR=5,10,15,20;BYMINUTE=15;

Example 2: multiple schedule frequencies together: The example provided runs every day between 5:30 PM and 7:30 PM, executing every 10 minutes during these hours.

FREQ=DAILY;BYHOUR=17;BYMINUTE=30,40,50;BYSECOND=0;

&FREQ=DAILY;BYHOUR=18;BYMINUTE=0,10,20,30,40,50;BYSECOND=0;

&FREQ=DAILY;BYHOUR=19;BYMINUTE=0,10,20,30;BYSECOND=0;

Note: we can only start the schedule if the integration is activated. Once started, we can see the future runs of the schedule.
