Hi Omar Shan,
On IICS Data Integration service, there is no option to run the job continuously for now. To achieve your requirement, you need to use the Database Mass Ingestion service, Where you have the option to run the job in 3 different ways.
1. Initial Load ( Which captures everything from source to target)
2. Incremental Load (Job runs continuously and captures any new changes happening at source side)
3. Initial and Incremental Load ( Does initial load and then job runs continuously and captures any new changes happening at source side)
For Database Mass Ingestion you need a different license for which you need to talk to your sales presentative.
