Some Prilim questions
Hi
Spec:
O/s : Unix HP 11i
Tomcat : 6.0.18
J2sdk : 1.6
DB : Oracle 10g
Question
1) Which is faster JNDI Based Connection pool / ordinary JDBC based connection / close ?
2) In JNDI / context based Connection pool for the code given below
InitialContext ic = new InitialContext();
DataSource ODS =(javax.sql.DataSource)ic.lookup("java:comp/env/jdbc/MYSCEMA");
Connection conn = ODS.getConnection()
// Insert /Update /Delete/...
conn.close() --> What does this code do ? (return connection to pool or close the connection )
Googled /yahooed but non correct answers ....
Please advice
Karthik

Yes!! That is exactly I need to able to read this list. 3 Megawatti
minimum, forget about electronVolts. Even better 5 GigaWatt. Where
is the LHC when I need it ?? .... to generate some black holes ??

I did provide the correct answers, or rather, repeat them.

This may be true, but it *wasn't* the question. Local/Remote isn't
mentioned in the question anywhere.

Just for my own amusement, here is the original question in full:

<<<<< ends here <<<<<
Prizes for anyone who can spot the references to India or Ithaca within.
I think the real question is this: what is the result of this
calculation: ( any large prime number ) divided by zero?
The point I was so laboriously making, is that it's easy to post
irrelevant nonsense scraped from the depths of the internet. But it's
not helpful, so please stop it.

Go back to the original question: it clearly says JNDI DataSource (i.e.
a connection pool) versus straight-JDBC connections without pooling.

Since "TC is not" whatever you are talking about, why bring it up?

Technically, this nonsense is the digression. One does not generally
"digress back to" anything, but rather end the digression. But I digress...

In this case, the answer is still the same: the connection pool is
faster than using unpooled connections.

Christopher is generally a name chosen for male humans, and my parents
chose to follow in that tradition.
Look, Martin. I'm not trying to attack you politically. I'm trying to
ask you to carefully read questions before you respond. Your answers are
often ... confusing, to say the least. I have seen you answer some
questions brilliantly, which is maybe why I get so bent out of shape
when you give such an outlandish response.

In other words if you have an opportunity to attack someone instead of providing an intelligent
solution then yes by all means CHANGE the question (so you'll look good and the other guy looks like an idiot..) from a JDBC DataSource lookup to LDAP question..
if the question is a comparison of a local lookup vs remote lookups you will need a J2EE server and understand Remote architectures (which TC is not) and you will need to know how to setup and reference the remote object
so I disgress back to the question which is if I have a DB server in NY and I have a TC container running in India
how do I acquire the fastest response for a DB Connection for my client ?
I can think of 2 options which I will discuss offline with the client
allowing chris and his/her political attack machine to continue ..
in the meanwhile Microsoft continues to convert TC installations to .NET..

(May I Chris? Thank you in advance.)
So, Martin, (can I call you Al? I prefer Al - like the song), I'm
interested to know how you'll respond to this query.
I've carefully re-read this thread from the beginning to the point where
you responded with the following:
"the referenced jndi lookup in the webapp context is located in India
and the DB is in Ithaca NY the Indian JNDI lookup is considerably slower
than 'ordinary JDBC connection' from NY"
... and I'm wondering whether you had some off list conversation with
karthikn (the OP). Because I can't really see any way you could deduce
that the DB is in Ithaca. Or in fact that the JNDI context is in India.
(Well, apart from the distinct possibility that the OP is in the Indian
subcontinent.)
Al, your answer is utterly irrelevant - the correct answers being:
1. A JNDI connection pool is measurably faster
2. Return the connection to the pool in most cases, subject to
the implementation of the driver.
- so I am puzzling over the word Ithaca. I suspect that it's a riddle,
but I'm not making a great deal of progress, Al. Can you help?
Ithaca, I know - as I studied the classics for a while, is the home of
Odysseus. Is this a Homerian reference I wondered?
And yet, Al, you mention NY.
And India!
So I searched Google... Of course!
The only result that mentions Ithaca NY and India in its title is:
"Bikram's Yoga College of India - Ithaca, NY, 14850 - Citysearch"
And there we have it, Al - you're a genius! 14850!
But what is the meaning of 14850?!
Is it www.14850.com? Public Communications, Inc's website!
We're on a public mailing list, this must be it! But no... wait...
There's another possibility, ISO:14850! What's this?
"ISO 14850:2004 describes a procedure for measurements of gamma-emitting
radionuclide activity in homogeneous objects such as unconditioned waste
(including process waste, dismantling waste, etc.), waste conditioned in
various matrices (bitumen, hydraulic binder, thermosetting resins,
etc.), notably in the form of 100 L, 200 L, 400 L or 800 L drums, and
test specimens or samples, (vitrified waste), and waste packaged in a
container, notably technological waste. It also specifies the
calibration of the gamma spectrometry chain. The gamma energies used
generally range from 0,05 MeV to 3 MeV."
Al, I'm disturbed by this. India *is* a nuclear power, and this *is* a
public standard, but I think we're moving into dangerous territory here.
What are you getting at I wondered? Is there a deeper message regarding
nuclear power for OP to take back to his people?
A little more googling led me to Tarapur, where there's a nuclear waste
disposal and storage facility that, yes!, uses *vitrification*.
(I paused here, as I was thirsty and the second bottle was now empty.)
Tarapur, Al, Tarapur. What are you trying to tell us, I mused.
Wikipedia has 5 references for places called Tarapur, in these states
Maharashtra - the nuke plant, Gujarat & Bihar - otherwise unremarkable.
Madhya Pradesh - is one of the best known centres for very unusual and
attractive bandanas! Could this be it!?
Karthik, Chris, David, I nearly shouted out loud! *BANDANAS*
It was so obvious to me now, I was amazed that I hadn't seen it straight
away!
But then Al, I idly flicked the back button, to check the last link...
Tarapur, Orissa. Three stupas (edicts), put up by Emperor Asoka, have
been discovered at Tarapur recently.
I was stunned Al.
* Ashoka the Great *
It crystallised in my mind quickly as the breadth of your vision appeared.
** Ashoka the Great **
"He who regards everyone amiably"
I knew Al, from my classical studies, that Ashoka The Great was a Hindu
by birth but later converted to Buddhism after the battle of Kalinga.
He subsequently declared in his edicts:
“There is no country, except among the Greeks, where these two groups,
Brahmans and ascetics, are not found, and there is no country where
people are not devoted to one or another religion."
The GREEKS! ITHACA!
This reference confirmed I had arrived in the right place!
Your message is revealed Al, as a message of peace and understanding,
for Ashoka is famous for his message of freedom, tolerance, and equality.
I was worn out from my exertions, but gloriously sated as I collapsed
into a drunken stupor.
Peace, Al, Peace.

This is true: if your LDAP server is geographically far from your app
server, then the lookup of your JNDI object could take a long time. What
Martin doesn't realize is that Tomcat always stores JNDI-based
DataSource objects locally, so this situation will never happen.
Martin's statement is a red herring: true, but irrelevant.

Re: Some Prilim questions

I have no idea where you are going with this ... it makes no sense to
the original question.
If you mean the webapp is hosted on a geographically distant place from
the database server, then you'll have latency like no tomorrow
regardless of whether a database pool is used or not.
The point and reason developers use a database pool is the pooled
connections are already formed. Getting a connection is just borrowing
it from the pool and closing is just returning it after your all done.
Pooling makes sense because connection handshaking and authentication is
done once on the first call for a connection. Each successive borrow of
that connection is ready immediately without any overhead associated
with forming a new one.

the referenced jndi lookup in the webapp context is located in India and the DB is in Ithaca NY the Indian JNDI lookup is considerably slower than 'ordinary JDBC connection' from NY

JNDI based connection pool. The connections are potentially already
formed and ready for use when you call for one. Ordinary JDBC would
explicitly create a new connection everytime you need one with all the
costs associated with that.
> conn.close() --> What does this code do ? (return connection to pool or close the connection )
It's essentially pool implementation specific, but in most db pools, the
connection is simply returned to the pool and made available to the next
request for a connection.
