Componentization of Cobol Code.

Thanks for Stoping by.....

My requirement is bit odd rather than developing and maintaining the mainframe code, the objective is to modularize and componentize the Cobol Code.
We have a few objectives in place as

1. Reusability
2. Performance
3. Maintanability

I am not having any idea on how to start with the analysis.
More concerned in a way that componentization will lead to multiple passes of the data and more I/O activities.

Could anyone just give me a few pointers to where to look at in the code like I/O, validation, DB calls to find the oppurtunities for componentization.

Thanks
Anu

I'm not sure if I've understood the question well enough. However, with the kind of idea I get from your sentences posted here; please have a look on these links:

Usually, these kind of very-complex-projects are carried out using some tools. One, for example, is IBM's Rational Assets Analyzer, but there are many more.

a quick and dirty search with IBM redbooks software reuse gave this link

Thankyou Anuj, Ofer71 and Enrico.

I am all over google to find the answers. However, there are very few documents which has the detailed approach to enable CICS to Legacy Code.

I am looking at the analysis method on how we can enable SOA on CICS-COBOL-DB2 code.
For the time being, i am reading the following redbooks.

SOA Transition Scenarios for the IBM z/OS Platform

SOA Architecture Handbook for z/OS

Thanks,

Anu

Enrico,

However, there are very few documents which has the detailed approach to enable SOA to CICS Legacy Code.

I have put that wrongly. My objective is to componentize the code and enable that as a service within mainframes.

Thanks,
Anu

well from the question flow You have to clarify Your ideas first,

I think you're starting the wrong way on this one. Unless reusability and maintainability are part of the project design, going back and retrofitting the code for them can be a nightmare -- and require as much, or more, resources as the original development project. Furthermore, performance tends to be worse since reusable modules must take into account things that project-specific code doesn't. So to start with, your goals are contradictory.

Furthermore, reusability and maintainability have very little to do with using code as a service -- you're attempting to compare apples with pomegranates here. You would be doing yourself a favor by going back to the project sponsor and clarifying whether you are developing software as a service or reusable, maintainable code.
