Re: What would you do without RPG?

I have to say, you do not see teams of nervously sweating DB Admins sitting around worrying about DB2 performance, like you do in every Oracle shop I have ever been in. There has to be a reason for that, and it usually revolves around DB2 doing whatever job it is tasked with reliably, quickly, and without getting in the user's way. Even if that job is emulating a file system or file system access method, as it does on "i".

When you look at cost, scalability, capability, and support, DB2 is almost always a better choice than Oracle. Which is again, a major reason the 400 and descendants are such good machines- in my thinking.

YMMV of course, that is just my opinion. But more projects succeed with DB2 than with most competitors, save for SQL Server. The reason for that is just there are more Microsoft people than IBMers- occasioned by the cost barrier to entry. Which is again, just my opinion. :)

You make an interesting argument that DB2 cover "almost 100% of the SQL

You also left out the part of my post about upsetting DB2 diehards. Which
apparently it did.

In addition DB2 SQL implementation limited.
DB2 for i covers almost 100% of the SQL standard, while other databases
are far behind, even ORACLE.
That does not mean that other databases do not include features that are
nice to have. Those database manufacturers need sales arguments.

No update from joined data
Add an instead of trigger to your view and voilà joined views or views
including CTEs are updatable.

It's going to grind all the iSeries diehards, but I would tend to agree.
In addition DB2 SQL implementation limited. No update from joined data,
no update from a CTE, the idea is to force SQL back into the iterative
structure of RPG. If we omit the things that make SQL set based then
DBA's don't have much to do.

That said, I will take the scraps that IBM throws us. It's still better
than reading file A, then chain to file B, then chain to file
C................that got old somewhere around 1992.

I would think it's because the majority of RPG shops don't use a database.
They use indexed files, but not a database. No referential integrity, no
triggers, no cascading deletes. CHAINs and SETLLs and such. You don't need
a DBA for that, do you?

While that sounds reasonable, if true, it begs the question: Why are
there so many Oracle and MS SQL Server DBA's, and so few IBM I DBA's?
It's not that Oracle and SQL Server do more work, and I doubt that IT
directors in those shops are just looking for people to give money to.

SAP on i:

SAP on a pSeries and an Oracle database.
He also told me as long as they worked with the ORACLE database
there
were
everyday 3 DBAs who did nothing else than balance indexes and adjust
buffers etc.

that has to be make work, no? There must be code an ORACLE admin can
run that automates whatever it is that has to be done to keep the
database functioning.
