Property: whenever executed parallel Non blocking invoke à true (multithreading) XSD: i/p i1 ,i2 int o/p result àint create variables:
Assign 1 : Input invoke 1 i/p Input invoke 2 i/p Assign 2 : Invoke 1 o/p add Assign 3: Invoke 2 o/p mul Switch: Case1: add> mul Case2: mul > add Assign 4: Add result Assign 5: mul result Create the property: Double click on partner link (ex: PL _add) Property click Property name(non blocking invoke), property value (true) ok Note:
Flow: Loan approval process à when ever we know the flow of our project we work with “flow activity” . i/p loan amount, duration Flow – N : When we are not sure of the flow of the project and don’t how many web services we need to invoke we will dynamically process at runtime by using “flow activity” . DB –poll + synchronous _read to file _write: Fault Handling Frame work: 2 ways to handle the faults
Ex: In process have multiple BPEL’s are then if we created throw, catch, catch all for ci validation BPEL then it applicable for that BPEL only not applicable for total process project.
Ex: Process project all BPEL process handled. 2 types of faults
Ex: amount> 50,000 , length cc number = 16 digits
