Performance testing for Mainframe CICS APIs

[Abhishek Banginwar]

Hi all,

 

Currently I'm working on a project where i need to test APIs which exist in mainframe Z/OS. From what i found out by googling is,

its a java based code in mainframes.

 

System testing/functional testing is using a client called IWS to send receive the request response. Unlike SOAPUI, this one does not show XMLs which its sending or receiving.

 

My queries;

1.  Is performance testing of mainframe CICS API possible?

2. If yes, which protocol?

3. If not possible with LR, alternative method if any?

 

if this has been already covered, please let me know.

 

Thanks in advance.

“a java based code in mainframes”

 

At the most primitive of levels, what you have is the following

 

A=Create Socket

Open Socket (A)

Send on Socket(A) some request

Receive on Socket(A) some response

Close Socket(A)

 

So, at the most primitive level, you could use windows sockets to produce and deliver load though a remote API interface.  But your application service residing on the mainframe might have a more robust interface that it can take advantage of, so moving up the OSI stack…

 

For a presentation layer view, perhaps a C level API exists, something that you can load a DLL for a Windows user and be able to affect remote procedure calls to the API on the mainframe.   You could potentially use either a C template virtual user or a roll your own in Visual Studio type of virtual user

 

For an application layer view, perhaps there is a Java client complement, thinking in the CORBA-context.   In such a case you may be able to leverage existing Java code for a Java template virtual user.

 

Three potential access models, Winsock, C Template  (with client API code to the mainframe based Service interface) | DLL Virtual User in Visual Studio, or Java Template.

Hi,

Give a try with ( Terminal Emulator) RTE protocol ,Donno if its works, RTE works with Mainframe Appln.... 

Thanks,

Rajesh

Try using RTE(terminal emulation) ..I had used this protocol for
mainframe cics.. and was able script.. u have to make the initial
setup to launch the application by giving port num and connection
info.. rest everything will be a cake walk for u..

hi,
thanks for the information. today i found out from system arch that this is proprietary protocol which also uses encryption/decryption as well.

after some discussion, he has accepted to open up some ports to allow generic soap request to sent to the mainframe. now i would just require to use web_custom_request function.

Sorry for the trouble.

If it is in Mainframe (terminal type ) all it is required to select correct session (screen type ) that all

It’s not a terminal, it is a service running on the mainframe

Oh sry for that (so i added that If ( quest're ) on my statement

Hi All,
I need to peform load testing for hyperion application (Tool).
Can anyone guide me ,as to how to make environment settings for hyperion to make it supportable for load runner.

Just as an FYI, testing CICS is winsock protocol. Hope that helps.

Thanks John. i'll try that out.
