Re: Question about UDB on iSeries

Another example of ease-of-use, which can translate to lower costs:

I was rented out to Pillsbury some 10 years ago, on an AS/400 project. They 
also had mainframes. I mentioned to a mainframe developer that I was going to 
add a field to a physical file (a column to a table). They did have a 
cross-reference tool (Abstract Probe) that would recompile dependent objects 
and preserve the data. This was accomplished in minutes. The other fellow said 
it'd take 2 days to get that done on the mainframe. I don't have the resons 
why, but there you are.

On converting your applications - seems to me it'd be easier and less 
error-prone to convert the COBOL to another platform that also uses that 
language. It certainly won't happen on a Windows box. I'm not sure of the Sun 
sustems.

As others have said, from the earliest days of the System/38, IBM has provided 
many of the utilities that system analysts need to write on mainframes. There 
is all kinds of history and logging going on that is not going to happen by 
default on the big iron. This is one reason that iSeries might be a little 
slower - mainframes are known for raw power, massive data crunching.

But there is still some room for tools like those already mentioned.

Someone listed a link to a porting page for DB2. Here is a general one for 
porting to iSeries:

http://www-1.ibm.com/servers/enable/site/porting/iseries/

It includes links to architecture informations, etc.
