Question
what is the difference of using transformer in service &
direct invoke of service?
Rank Answer Posted By  
 Question Submitted By :: Guest
This Interview Question Asked @   Siemens , Capegemini, Capegemini
I also faced this Question!!   ALL Interview .com
Answer
Invoking a service using a transformer, you can invoke multiple services in a single map step and every service is invoked using a separate thread thus executing parallely and improving performance.

Answer
While invoking a service as a transformer we can map only 
the required fields.
IF we invoke a service directly , the pipeline values of 
the called service will be included along with the current 
pipeline value and have to drop the unwanted variables 
explicitly.

Answer
1. Multiple services can be invoked via multiple threads that are executed in Parallel and thus Improved performance.

2. Also, the pipeline memory will be optimally used as the pipeline variables need not be carried over multiple flow steps.

Question
i am having a csv file and it is passed to the tokenize and 
is passed to the three different fields without setting the 
indices property.
my question is to which variable which value goes or all 
the tokenized fields tobe passed?
for eg:santosh.giridhar_satish_satish.csv-->tokenize what 
will happen

This Interview Question Asked @   tcs
I also faced this Question!!   ALL Interview .com
Answer
pub.string.tokenize service takes 2 inputs, the string to be tokenzied and the delimiter character which is comma in this case as the file is .csv file.

It produces one output valueList at a stretch which is the array of strings tokenized from the inString.

I don't think there is scope to set indices property and map each value to one variable on the output.

Thanks

to know about Tibco tool.Please help me out guys....
Rank Answer Posted By  
 Question Submitted By :: Vishnupriya
I also faced this Question!!   ALL Interview .com
Answer
The IDE for TIBCO is TIBCO Business Works, which is more like a SDLC tool. It is not similar to Eclipse in any manner. This tool could be used to create, generate and fetch data from web services. However it provides much more facilities than this. Its main usage resides in the fields of Financial services, Telecommunication Retail Banking etc.

Question
In which case the transformers should not be used...?
Rank Answer Posted By  
 Question Submitted By :: Srisrikanth.m007
I also faced this Question!!   ALL Interview .com
Answer
if the output of one transformer is the input of another 
transformer in the same map,the reason behind there is no 
guarantee that IS executes the transformers in a sequential 
manner.

Answer
The output of one transformer cannot be used as the input of another transformer in the same MAP step.
Transformers in a MAP step are independent of each other and do not execute in a specific order. When inserting transformers, assume that webMethods Integration
Server concurrently executes the transformers at run time.

Question
We have created a insert notification ,is there any way to
process the document in the subscriber without publishing it

Answer
When you create an Insert Notification or any other, It by default creates a Publishable document associated with the notification and when a DB change Happens, then the activity will be notified by the corresponding Notification as a Publishable document to Broker. This is an auto Publish.

Just create a trigger with this document type and a subscribing service; You would not need to write a publish step in the Subscribing service again.

Question
In which case we are not advised to use Transformers...?
Rank Answer Posted By  
 Question Submitted By :: Srikanth
I also faced this Question!!   ALL Interview .com
Answer
When exception occurs in a transformer, it swipes off the 
pipeline values and 'lastError' will not have the service 
stack too. So Transformer is not advised when there is a 
possibility of exception from the service used as 
transforner. Ex: addInts service, this would throw 
exception when there is 'null' input. So if there is a 
possibility that one value may be null, do not use 
transformer for this value trnaformation. 
Also addInts is a common service that can be invoked by 
many services. When an exception is caused by addInts being 
used as transformer - you can guess how tough it would be 
to track down the service that failed with the exception.

Answer
The above answer is partial correct and this is also one of 
the pitfalls of get last error.It will catch the latest 
exception and overwrites the previous exception,so we cant 
guarantee all the exceptions are caught and accounted in 
getLastError.

Question
explain try and catch block briefly
Rank Answer Posted By  
 Question Submitted By :: Giridhar2767
This Interview Question Asked @   accenture
I also faced this Question!!   ALL Interview .com
Answer
To handle exception/error we use
try and catch block with the use 
of sequence.

Remember Exit on
               .
               .
.......................................... 
.                                        .
.                                        .
SUCCESS                                   FAILURE

Exit on Success:If there is error in 
               any subordinate service
               it will be run.

Service1
Service2
Service3(here is error)
Service4
Exit on Success will run all 4 services.


Exit on Failure:It will exit on that service
                which has any error.

Service1
Service2
Service3(here is error)
Service4
Exit on Failure will run only Service1 and Service2.

Syntax::
Sequence(Main Block)[EXIT ON: SUCCESS]
Sequence(Try Block)[EXIT ON: FAILURE]
Sequence(Catch Block)[EXIT ON: DONE]

I also faced this Question!!   ALL Interview .com
Answer
It is possible to establish the application like such, but
incase of DB goes down then this middleware tool will be of
no use.

Also, otd is mandatory to connect to DB, here we use 2 otd's
to establish connection.
