Project fault – policies process

XSD:

i/p  i1,i2 àint

o/p  result àint

• Copy fault binding .xml, fault policies.xml

  Post inside project(c://j developer/my works/application _ Ramesh 2 /project)

• Open composite .xml à source code

  <Services>

<property name = “oracle .composite.faultpolicy file”>

Fault – policies.xml</property>

<property name = “oracle .composite.faultpolicy file”>

Fault – bindings.xml</property>

<component name =”BPEL process1” version =”1.0”>    

Assign 1 :

Input  invoke 1 i/p  

Assign 2 :

invoke  o/p o/p Catch: Name space URL = http://remotefault Local part = remote fault  

Assign 3 :

o/p  partner link not available.

Binding fault non – reliable fault

Remote fault retriable fault

If partner link rejried  remote fault

JNDI name gives wrong  JCA binding fault

WSDL miss-match  Binding fault  

“Ora – human Intervention”: starts the action where it’s stopped

Ex: it’s stopped at invoke

BPEL  faults tab  reversible  click

Variable:  select invoke

Recovery Action:

Click on  Recovery

Starts the action when it’s stopped  

Common fault you faced:

• Remote fault
• Binding fault
• Selection failure
• Time out exception à when there is a delay in response we can get time out error
• 500 error: when the deploying time 500 errors show that means server not working

  Compensation handles: (rollback action)

• Benefits role back in “asynchronous”

  Compensation Handles: (Rollback action) Benefits role back in “Asynchronous”

Create 3 variables:

• Add – int
• Mul – int
• Div – int

XSD:

i/p  i1,i2  int

o/p  result  int  

Assign 1:

• Add =0
• Mul = 0
• Div =0.0

  Assign 2:

I1+i2 = result  

Assign 3:

I1*i2 = result  

Assign 4:

I1/i2 = result  

Assign 5:

o/p:

concat(‘Addition=’, Add, ‘multiplication=’,mul, ‘division=’,div)

Then here is the blog post on Oracle SOA Training Online.

A6  o/p 0 = add

A7 o/p 0 = mul

A8  o/p  0.0 = div

Switch:

Lable : div = infinity Expression : div =’Infinity’ or  div = ‘- infinity    

Money transfer one account to other account:

Create ICICI DB table :

Create HDFC DB table:

    create  one global variable

amount   int

invoke 1   operation (select - update)

invoke 2  operation (update)

invoke 3  operation (select - update)

invoke 4  operation (update)

invoke 5  operation (select - update)

invoke 6  operation (update)  

ICICI DB

4-10  update only ,select

8-10   parameter/tempid,

SQL/select a/c no, name, amount from ICICI DB where (A/c no = temp id)  

A1:

Input /from a/c mo  invoke 1 i/p /temp id  

A2:

Invoke 1 o/p/Amount  amount(variable)  

A3:

Amount (variable invoke 2 i/p /amount)

Invoke 1 o/p /name   invoke 2 i/p / name

Invoke 1 0/p /a/c no   invoke 2 i/p / a/c no  

A4:

Input /to a/c mo  invoke 1 i/p /temp id  

A5:

Invoke 3 o/p/Amount  amount(variable)  

A6:

Amount (variable invoke 2 i/p /amount)

Invoke 3 o/p /name  invoke 2 i/p / name

Invoke 3 0/p /a/c no invoke 2 i/p / a/c no  

A7:

invoke 1  o/p /amount  invoke 5 i/p /amount)

invoke 1  o/p/ name invoke 5 i/p /name

invoke 1  o/p/ a/c no invoke 5 i/p /a/c no

invoke 3  o/p /amount  invoke 8 i/p /amount)

invoke 3 o/p/ name invoke 8 i/p /name

invoke 3  o/p/ a/c no invoke 8 i/p /a/c no

A8:

“Transaction roll backed due to fault”  

A9:

“Amount transfer action completed”  

Fault variable

• XSD: (take one element)

<element name = “fault”>

<complex type>

<sequence>

<element name = “details” type =”string”/>

<element name = “code” type =”string”/>

<element name = “description” type =”string”/>

</sequence>

</complex type>

</element>  

• WSDL (mention /write last of the page)

   <WSDL : message name = “fault message”>

<WSDL : part name = “pay load” element = “client : Fault”/>

</WSDL : message>  

BPEL:

Create Variable = name = Fault Variable Message = fault message ok  

Throw:             

Name space :

http:// saiteja .com/test

Local part : test Fault Variable :  Fault Variable <variable name>
