Explaination of Oracle SOA Adapters

 Adapters

• It is a reusable concept.
• Invoke using for

1. call concrete WSDL
2. call adapters

• File adapters
• DB adapters
• FTP adapters
• JMS adapters
• Oracle BAM adapters
• Oracle Application adapters
• SAP / TIBCO adapters(3^rd party adapters)

  For – each:

• Read file/ records one by one based on polling frequency
• Root node  right click Add XSL node  for – each

  File Read/Poll: Interview Question: whenever you take an adapter each adapter creates

1. .jca (java connecting architecture)
2. .WSDL

File Adapters:

10g	11g
Read/poll	Read/poll
Write	Write
synchronous Read	Synchronous Read, list files

File poll/read to file write: (empty BPEL process)     File poll                       These 3 operations we are taking “empty ”BPEL process DB poll JMS consume Note: Empty BPEL process “Receive activity” Create instance -> only for input receive activity.   file read:

• polling frequency
• XSD [Native format]
• input file path(physical)
• Delete files after successfully retrieval

  File write:

• Sample XSD(which format display output file)
• Outgoing files path/logical name
• File naming conversion

  Assign: Input file  invoke input   Synchronous Read: Only once it read in between process.

• In between process means -> Between receive and reply activities
• It will poll only one file(It contain multiple records)

Case1: Static file name input: Synchronous read: 6 -8 File name(sample.txt) (or)*.txt   Case2: Dynamic file name input: Synchronous read: 6 – 8  file name (dummy file name) wxyz.txt Invoke 1: Double click properties

Name	Value	Type
Jca.file.filename	value	input

  Testing (EM) Input: any string data .txt Invoke 2: Double click properties

Name	Value	Type
