Subject: RE: No DBAs needed on
AS400
Comments were made that DB2 and AS400s are not "open".
Does this mean that you couldn't write a client/server program to access data
on DB2 (say using C++ from Windows 2000)?
RUMBA/400 formerly pc support connects to the AS400 from a
windows pc. Last I knew, the AS400 data need to be converted from EBCDIC
into the wrkdoc area for ASCII in order for Rumba/400 to work with it
correctly.

Subject: RE: No DBAs needed on AS400
Thank you for all the replies that I have received.
It sounds like a version of DB2 comes along with the OS, or a
full fledged version of DB2 can be installed. From what I have heard
about their AS400 system, they can access their files directly - without going
through a database. This reminds me of my COBOL days on VMS. It sounds
like DB2 can be configured to use files, which would mean that you could
either update the file directly or go through DB2 - is this correct? I
can also make another VMS relation here - we had a tool called DataTrieve
which you could configure to use regular files. You could then issue SQL
like statements through DataTrieve against your files. Is DB2 like
this? Somebody needed to configure DataTrieve before it could reference
a file - what about DB2? Unless "they" never changed/added files on the
AS400.
Comments were made that DB2 and AS400s are not "open".

I'm off to find on-line docs...
Answers to some questions:
>Does it have DB2 as the database?
He didn't say that it was running DB2.
>If you are performing queries from Oracle to DB2 (SQL
Queries), that is being performed through Oracle's gateway product.
We are not doing this.

Jay - I can see the manager's confusion.
After all, one expects computers to
become easier and
require less effort to maintain as time goes by. I
forwarded your question to another list that has some AS/400
programmers.
----------------------------------------------------------
On the AS400 you can run queries and use SQL even though the
machine is
configured to use files. Under the covers
it is still AS400/DB2.
----------------------------------------------------------
The AS/400 has a full-featured database built into the
operating system.
Originally it didn't even have a
name but IBM started calling it DB2/400
when they
found out that some people didn't know it was there. And you don't
need a DBA. Virtually all the functions that are performed by
a DBA on an
Oracle database, for example, are handled
automatically by the AS/400 under
the covers.
