Cary,
Thank you.
Could you elaborate on the issue of excessive database calls, which show up
as excessive network traffic?
I can picture a PL/SQL loop, which executes an SQL statement over and over
again. This would produce many database calls, and it might be possible to
remove the loop
Greg,
That's one case. PL/SQL is a really poor language in which to write an
application. The language tricks you into believing that writing a
scalable application can be accomplished in just a few lines of 4GL
code, but it's really not true. To write scalable PL/SQL, you need to
use DBMS_SQL.

I was asked today if I can use Oracle's extproc feature on the mainframe to
submit JCL. I said that I doubted it because the OS structure is so much
different than UNIX or NT, but I would look into

Please see the official ORACLE-L FAQ:
In some cases, NOT IN is better than NOT EXISTS. In
other cases, the opposite is true.
Moral: It never pays to discount an option out of hand
- eg, NOT IN often works very very nicely for
uncorrelated subqueries

On index-obsessed apps, you'll often see massive
amount of LIO to a target of a nested loop. ie, scan
mega table and then index probe the inner table for
every row of the mega table...
Generally you'll see smoke coming out of the index
root/branch blocks on the target table :-)

With the advent of bulk bind and bulk collection
facilities in PL/SQL, you can get very close to the
correct SQL mechanisms...its just that not many
people tend to do it, and you end up with a gazillion
'one-row-at-a-time' applications out there.

How about switching to incremental (from full) backups? Even if all you
do are level-0 backups?
My understanding of the difference between a full and a level-0 backup
(besides the obvious impact on any subsequent level-n incremental backups)
is that level-0 backups only back up database blocks
Tim, i'd be glad to hear someone else verify your statement as my
understanding is the the only difference between full and level 0 is
that full cannot be used as part of an incremental strategy, other than
that they both back up the ever used blocks.
Anyone else care to jump in on this one?
Joe Tim,
It is accurate to state the both full and level 0 have the same impact
on the database, and both backup all used blocks. It is also accurate
that a full backup cannot be used as a piece of an incremental strategy.
Although there may be rare instances (no pun intended :-) ) when you
Babette,
This is one of those from this old turd to that old fart messages. I've
been around Oracle since 1985 I love it too. But it sounds like the director
has a serious problem with new technology. Doing anything in COBOL today? Even
PeopleSoft is busy re-writing their code in C++.

I am very thankfull for you help ...
But it is not all...
Imagine you working at environment that doesn't know the
database, and need to solve problems.
So, the CPU is a item that you helped me to find out the user

In addition to Dick's comments (with which I agree)
Be careful how you approach this situation. If you wish to succeed, it
may be key to let the powers that be know that you are not proposing
