Folks are debating DBA skills in these forums. Ever tried to get
C/C++ skills? It's a b**** to get a good C programmer nowadays.
Actually, they are pretty easy to find in Australia. And cheap, too.
Same goes for VB and C# programmers, BTW. Nowadays it's harder to
find a J2EE guy than anything else, as a matter of fact.
Certainty the kids who wrote C when they were 16 and hit the job with
10 years experience don't exist anymore.
Yeah but they were never any good. I'm talking about professional
programmers. Not script kiddies writing TSRs for fun.
Point being, you wouldn't go back to micro-coding, you wouldn't go
back to assembly. Too expensive in labour, too unwieldy.
C/C++ is already turning into a niche skill.
Begging your pardon, that's the biggest pile of marketing dung
out there. I understand it's not sourced from you. But it's
totally untrue.
Which language do you reckon the ENTIRE edifice of GNU and open
source software is built on? And Linux? And Apache? And most of
the opensource appservers? And just about every other piece of
commercial software for the PC environment? Adobe software,
for example? Symantec? The entire edifice of Windoze/SS/Microsoft
Office software? DotNot itself?
Java/J2EE??? Pah!! Freakin' NO WAY in the darn world!!!
Do you think there is ONE LINE of Java in ANY search engine
out there? It's ALL C and C++, Apache, opensource OS and s/w and
script languages, Serge. I'm in the thick of it now, I know what I
see. 3/4 of all that crap you hear about Java/J2EE and internet
technology is TOTALLY and UTTERLY false: a complete hoax!
Don't believe the marketing BULL that Java has taken over the world:
it's the biggest hoax I've ever seen! DotNot and c# alone have
MORE developers than ALL the Java dungheap!
The abstraction layer just keeps on rising because Moore's law and
inflation favours throwing Hz and bytes at any problem over brain.
You can't throw Hz at a J2EE app and expect it to run well.
Believe me, I've seen that approach daily. For 4 looong years.
It never worked, not even ONCE!!!
I've seen piddly apps with less than 200 tables in them
throw a big iron server (name with-held but it has 3 letters)
completely out the window. The darn thing is so moronically
inefficient it doesn't matter how much hardware you throw at it,
it just WON'T work with any SIGNIFICANTLY large app.
See above. You, I, we are too expensive. We expect our salaries to rise.
Nope. Wrong again. Middle age experienced techos are
a dime a dozen and dirt cheap compared to snotty kids who
expect to be on the way to the 5th million by age 28.
Besides, the middle age mob IS experienced, has had ALL
the training they need and has a work ethic that no
modern snotty kid can match. And it can learn c# dirt easy.
We are dirt cheap nowadays, Serge. We don't need expensive
training, we can read a book and make sense of it, we're past
the age of raising babies or taking long weekends on the booze.
The Java mob doesn't stand a hope in hell against that:
their learning curve for anything is ten times as high
and expensive. Don't believe the marketing crap you hear.
It's all rubbish peddled by IDE and snake-oil vendors.
DotNot beats the sweet bejesus off J2EE, any time you might
care to compare them with anything slightly more complex than a
moronic shopping cart. And there is very little Java in it,
if any.
Which do you reckon is gonna win, something that takes 2 days
and a mouse to learn, or something that requires 4000 pages
of just the basic user guide?
I was told many times over the last 4 years that without Java
I couldn't find a job anywhere. Complete hoax. Once I got
terminally pissed-off with the pile of rubbish I was being fed
at an IBM VAR and started looking, took me two months to find
one. Can't complain. And no, I didn't take a pay cut.
Quite the opposite. Then again, I never charged the silly
small fortunes of the y2k era...
Amen!
I see one or two Java jobs occasionally now and then, almost
never. Don't know where the shops are that are using Java, and
most certainly don't see any commercial applications using it.
I have seen a couple of file-manager-applets, but not much
else, or installation programs. Maybe inside intranet apps,
but even there never heard of many.
If there are commercial applications, they are either C++ or
scripted like PHP, Perl, ASP, or C#.
The rest what Noons said.
:-)
Again the deciding factor may be geography. I see a lot of Java
here in the US Pacific Northwest. See a lot of .NET too ... but
the interest in .NET seems to be waning and interest in PHP
increasing.

> Recoveries? Yeah, I seldom need to recover databases. But I think that a primary responsibility of a dba is to be able to restore a
database. :-) So, I'm a big believer to running backup/restore drills
if necessary to develop that skill.
How could running recovery drills be easier in DB2 than in Oracle?
This is a pure assumption. Apparently they have not been Oracle trained.
True. Nor had they been db2-trained prior to starting this project.
But I've got the same amount of experience with both databases, and
have built similar data warehouse projects on both. Both are great for
warehousing, with each having cool strengths. Oracle's partition
management and third-party support is fantastic. DB2's MDC (like
partitioning) is both fantastic and included in the base product. And
supporting and explaining db2 is much easier in my experience.
If I were to compare Oracle and DB2, ease of use or support would be the
last thing come to mind. The overall difference is so minor. Anybody with
slightly different experience would disagree with you.
No, partitioning is not included in DB2 Workgroup Edition. You can't even do
simple replications in DB2 without purchasing a separate product. Short term, useful Informix features (onstat, HDR, range partitioning)
are being added (or have been added) to DB2. But there's no reason to
rush and merge the codebases as long as customers continue to buy
Informix products like XPS, IDS, RedBrick, Cloudscape and U2. IBM
never merged IMS and DB2 on zOS, as both have healthy revenue streams.
And we never distcontinued DB2 on VSE/VM, as customers continue to pay
their license fees. There are many ways for a product to be viable,
successful, profitable, and do useful work for customers without being
the number 1 database on platform x.
Range partitioning is a new feature for DB2?
Range partiioning will be added to DB2 LUW in a future release. DB2 LUW
currently has hash partitioning and multi-dimensional clustering.

I found the idea that backup/recovery was an issue fascinating. When I
set up a server I create a backup routine, test it, and then forget it
except when configuration changes are made or to perform routine
verification that it still works. If it is something someone has to
think about daily they did a lousy job of it.
I must confess, though, that these days if my system did anything other
than melt down I would NEVER use a backup to recover. In Oracle I'd
look at flashback table, flashback query, flashback database, lots
of simple effective solutions before I ever went calling for the
off-site backup tapes. I think some of these people are still operating
the way they did in the 1980s.

Nothing like lots of capital letters to advance a technical argument!
You must practise Llap-Goch

" ... the Secret Welsh ART of SELF DEFENCE that requires NO
INTELLIGENCE, STRENGTH or PHYSICAL courage
The FANTASTIC SECRETS of the SECRET world-famous method of SELF
DEFENCE, kept secret for centuries because of their DEADLY POWER to
MAIM, KILL, SMASH, BATTER, FRACTURE, CRUSH, DISMEMBER, CRACK,
DISEMBOWEL, CRIPPLE, SNAP and HARM are now revealed to YOU in the
English Language by a LLAPGOCH master AT HIS OWN RISK, PROVIDED you
promise to MAIM, CRUSH, DISEMBOWEL and so on ONLY in SELF DEFENCE.*
* This is just to cover ourselves, as you will understand.
WHO IS THIS MAN?
This is the LLAP-GOCH MASTER who will reveal to YOU ONLY the
SECRETS of LLAP-GOCH. He is a fully qualified leek coloured belt first

WHY 'At his own risk'?
BECAUSE if his fellow masters of LLAPGOCH DISCOVER his IDENTITY, they
will PUNISH HIM SEVERELY for revealing the DEADLY secrets he had
promised to keep SECRET, without giving them a piece of the ACTION, and
also BECAUSE of the TERRIBLE risk of PUNISHMENT he runs under the

WHAT is LLAP-GOCH?
IT is THE most DEADLY form OF SECRET self-DEFENCE that HAS ever been

I thought someone was joking. Range, hash, and list partitioning
and subpartitioning have been in Oracle for close to a decade.

I have used range partitioning on DB2 for z/OS (it has been available for
over a decade) and I think it is over-rated. UNION all views on multiple
tables works better IMO from an admin perspective, and yields excellent
parallel processing benefits on DB2 LUW.
Of course, for massive parallel processing, real database partitioning is
already available with DB2 LUW using DPF. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |
