Hi,

Would like to know if

1. Anybody has carried out a comparison of various schedulers like TWS OPC, CA-7, Zeek, ESP etc.

2. Also do these product vendors also provide any migration tools from one scheduler to another?

Any pointers / info would be highly appreciated.

Neil

Its not a good idea to compare one product with another product (moreover if the vendors are different). Every product has merits as well as demerits over others.

Then let me rephrase.... What are the merits and demerits of these schedulers?

As suggested, its bad to compare.

But if you really wanted to do, materials are available over net for various schedulers. Find merits/demerits of each over other & LET US KNOW, we can keep/use for future references.

Hello,

Possibly, i misunderstand, but if an organization is making a decision on buying a product or changing from one product to another, comparison is critical. Without comparing, i have no idea how such a decision would be made?

100% of the software acquisitions / replacements that i've been involved with were based on rather in-depth comparisons.

For my $.02, what is important is on what basis the comparisons are made. The first order of business is to define what is needed and then measure how the various competing products meet those needs.

You might start with interviewing major users at sites that use different systems. Take them to lunch, also.

I have recently completed a project in which a lot of software packages were compared and a recommendation to purchase was made.

This involved reading tons of documentation, talking with users of each package, arranging vendor presentations with Q&A sessions, follow up vendor questions.

There are other things to consider, such as how much workload is required to transfer from one package to another, and would this cost outweigh any immediate or mid term savings. Especially dual license fees - bummer !!!

Can you get a reduced cost deal if you select multiple packages from one supplier ? or will the new supplier do a "loan" deal until conversion is completed. Will the new supplier perform or assist in the conversion ?

And lots lots more similar questions all add up to the final question - will the bean counters buy it icon_biggrin.gif

Thanks for the valuable inputs and cost considerations to be kept in mind. But before I start off the discussion with various users & vendors, I wanted to know if there is any site or agency which has published such a comparison report. My intention is to understand the thought process involved and also the various factors (technical & operational firstly) with appropriate weightages which can be used to eliminate the plethora of products available in the market. Once I have cut down my list, I can concentrate on the other significant aspect of cost and try to build a business case:-)

I would guess that the complexity of the analysis depends on the type of products being evaluated. Here are a couple of things we looked at.

1) Must have functions - also MISSING functionality
2) Would like to have functions
3) Vendors 2 year development plans for this product
4) Interfaces with existing products - will changes be required
5) Resource estimates from other groups, e.g. sysprogs, ops support, to implement and maintain
6) User education
