Difference Between Connect,Create Session

Hi,
What is the difference between connect , create session ?
Regards,

But i grant the user connect but when i try to logon by the user i got error you don't have right to create session?I don't know what you have.
I don't know what you do.
I don't know what you see.
It is really, Really, REALLY difficult to fix a problem that can not be seen.
use COPY & PASTE so we can see what you do & how Oracle responds.
Oracle is too dumb to lie about what is wrong.

Difference between connection, session and process

Hi all,
Can anyone please update me on the difference between connection,session and process.
Thanks in advance,
- Sri

I got this useful note by googled in net. It describes session,connection,process gracefully.
A connection is a physical circuit between you and the database.A connection
might be one of many types -- most popular begin DEDICATED server and SHARED
server. Zero, one or more sessions may be established over a given connection
to the database as show above with sqlplus. A process will be used by a session
to execute statements. Sometimes there is a one to one relationship between
CONNECTION->SESSION->PROCESS (eg: a normal dedicated server connection).
Sometimes there is a one to many from connection to sessions (eg: like
autotrace, one connection, two sessions, one process). A process does not have
to be dedicated to a specific connection or session however, for example when
using shared server (MTS), your SESSION will grab a process from a pool of
processes in order to execute a statement. When the call is over, that process
is released back to the pool of processes.

Difference between connection pooling and simple connection

Anybody please tell me what is the Difference between connection pooling and simple connection and also where we define connection pooling and how.
Thanks
Please reply soon

Creating and closing connection to the database is a relatively slow process. Equally connections use database resources so you can't just open as many as you want.
A connection pool maintains a number of open connections throughout the lifetime of the application. Instead of opening and closing the connections your application just "borrows" them from the pool when they're needed.
If the pool runs out of connections it will usually create new ones as needed until you reach some predefined upper limit.
A good connection pool will also manage connections which have failed for any reason, and report code which fails to return connections to the pool (ie connection leaks).
The number of connections created at startup is referred to as the "low water mark" and the maximum number that the pool will allow to be opened at any given time is the "high water mark". If no connections are available client code will generally block until one is released.
If by "defined" you mean where can you get a working implementation then your database or application server vendor is likely to provide one. Also the Apache Jakarta Commons includes [url http://jakarta.apache.org/commons/dbcp/]an implementation which you can use with any JDBC driver.

Difference Between connect and connector steps

Hi All,
What is the difference between connect step and connector step in a workflow?
Thanks
Narendra

Hi Narendra,
Connect: Connects the two steps. These two steps are on the same page of MS visio.
Connector: Connects the two steps of WF if these two steps are on different pages of MS visio, as in case of a huge WF design you can use multiple pages of visio. This is why we have only one point of connection at this icon. It automatically connects the step connected to it to the first step on the next page.
Hope this is clear.

Dheeraj.

Difference between PR created in ME51n & CJ20n

Hello Experts,
What is the diffrence between PR created in ME51n tcode and CJ20n - Project builder tcode.?
Will both PRs wil be stored in EBAN table?
If possible can you please tel me steps to create PR in CJ20n?
Thank you in advance for your valuable help.
WR,
Nilesh

Nilesh,
Not much difference between PR created in ME51n tcode and CJ20n.
You can cretae PR in ME51N by using the account assignment category P,but only the difference is if you will cretae through ME51N the PR number will not get updated in to project and if you will create PR in CJ21n You will be able to see the PR number and the follow-on document for that PR in to project itself.
Yes you are correct bothe PRs wil be stored in EBAN table only.

What is the difference between connecting a printer via USB or Ethernet ?

What is the difference between connecting a printer via USB or Ethernet ?

When a Printer with an Ethernet connector is connected via Ethernet, it becomes a peer device on your Network. It is available whenever it is on for all users on your Network.
When connected via USB, it relies on your computer to "Share" it onto the local Network. It is only available when the attached computer is on. It takes resources from that computer to facilitate printing for any User.

Differences between cookies and sessions

Hi there,
I want to learn the differences between sessions and cookies in PHP.Please help me.
Please let me know if there any video demonstrations that explain sessions and cookies.
Thanks in advance.

Cookies and server side sessions are related in that they are both ways to persist data. This is required because of the fact that http is a stateless protocol, meaning that each request and response are independent transactions. Cookies are stored on the client. You might use them to store the contents of a shopping cart, or a user login id for a particular site. Or you could store a setting so that the user is automatically logged in, similar to what occurs here in the adobe site / forums. You can set various options for when cookies expire. Cookies that persist when the browser is closed are store in files, otherwise they could be store in memory only. Cookies can be created using either client or server side code.
Server side sessions are created on the server with a server side scripting language. A session id is generated and stored as a token on the client (in an in memory cookie) so that the server can track requests from the same originating client. Session variables are ways to store data related to the session on the server. Sessions use server resources which is why you should only use them when necessary and destroy them when done. When the session is destroyed, the session variables are gone so if you want to keep them for later you can store them in a database or store them in a cookie.

Hope that helps

Difference between connection = null and connection.close()

is it correct
connection = null means connection object is eligible for garbage collection and does not return to connection pool
and f or
connection.close() means the connection object return to the
connection pool
is there any other difference between this ....?????

"connection = null;" is just like any other similar Java statement, it removes that reference to the object. If that was the last reference to the object, then it becomes eligible for finalization and garbage collection, with no guarantee that either will actually occur. However, normal connection pool implementation will have a seperate reference to the connection and if the connection has not been returned, will most likely consider the connection to be "leaked" - allocated but never returned, and unusable.
connection.close(); is a normal JDBC connection method; it (usually) closes the associated objects and releases the connection; it's not uncommon to explicitly close statements and resultsets instead of depending on connection.close(). A connection pooling implementation that works by extending the Connection class MIGHT change the meaning of close() and instead of actually closing, return it to the pool instead. Personally, I would consider such an implementation to be evil and a blight on good programming practices; changing the action of such standard methods is bound to cause trouble, IMHO. More normally, if you were using connection pooling, you would NOT close the connection, but rather call some special method to return the connection to the pool.

Difference between CONNECT and CONNECT As SYSDBA

Hi All,
Can anyone explain me... what is the difference between this two..
SQL> SCOTT/TIGER@my_service;
you get only Scott related objects.

you get all SYS objects also..
What is happening inside.. how can u allow scott such as ordinary user to login as SYSDBA and giving all datadictionary access..
Thanks in advance

Difference between the "Created" and the Created External fields

Guys,
There are two different fields I have seen in the Contacts Fields for CRMOD - Created and Created External - do we have any difference between them - can anyone tell me what exactly is the difference between them ?

No difference right now. In the future you will be able to import into "Created External".

Difference between Invoice created date and billing date.

Hi Gurus,
I opened the Billing Document in display mode(T.Code:VF03).In header data I found two tabs one is Created On and another one is Billing Date. Here in the billing document the both dates were different.
Please let me know the difference between Created On date and Billing Date.
your afforts are highly appriciated.
JYothi.

Dear Jyothisd,
Invoice created date : Invoice created date is nothing but the date on which you have created the invoice.
Billingdate:Billing date is the date on which you suppose to do the billing for respective customer. Tease billing dates will be proposed to invoice from sales order if it is order related or else actual goods issue date is proposed to billing document as a Billing date if particular billing document is delivery related.
If you want you can change the Actual billing date the result is invoice created date.
Please revert if you want any further clarifications
Thanks&Regards

What is different between connection and session parameters of dispatcher

I can not find any info about the difference.
I think "connection" is the connection between a dispatcher and a client, and "session" means the connection between a dispatcher and an instance.
but I am not sure about it. am I right?
there is another parameter named pool, it is used for what?
the pool for connections(i.e. "session") between a dispatcher and an instance?

After authentatication username/password database session starts whereas how user request will be handel it will be defined by conection.Either dedicated or shared Server.If U have not enough resource to handle user request and also you have application that is not using very long runing query then think to use shared server conection and if U have enough resource and very long runing query or transaction think about Dedicated Server.Both are different "SESSION" and connection.Conection determine hove request will be handled either by sharing resources(session memory,run time sql,bind variable) and
process through (DSPATCHER and SHARED SERVER ) process or every user will have their own dedicated resources or Server process.
Both in both cases after user/password session get created .it is the conection from client to database.

Difference between Item created under Material Master and Equipment

Hello Expert,
I am bit confused in Item created in Master and Equipmet:
as per my understanding : Item created in Item master belong to some BOM in BOM defines the structure for the Item.
Then what is exactly served b equipments?
The equpments are serialied Items with some different structure or they are derived from BOM?
Please guide me to understand this concept.
br,
Pushkar

Dear,
Check what I found: material master is used to describe an item, usually stockable, that is purchased, manufactured, sold, inspected, serviced, etc. A material master is usually created when there are multiple quantities of an item, say a product that is being manufactured.
A material master may have a serial number profile entered in order to allow distinguishing between the different copies of the same item. For stocking, inspecting, sales, manufacturing, etc; the exact serial number(s) being transacted will need to be specified.
Depending on the serial number profile specifics, each SN may get a unique equipment master, which records information specific to the material-SN combination (not just about the material in general). For instance, if a product sold to a customer is returned for service, that material-SN (=equipment master) will have a record of the service order used.
For items which are never inventoried but for which information particularly PM transactions are recorded, an equipment master without a material master may be created, for instance a piece of processing equipment.
So an equipment master may link to a material-SN combination, or may be a stand-alone.

Differences between Connect and ConnectNow Add-ins

Recently I took a look at the Adobe Connect 8 and I noticed that it useses different add-in for screen sharing. Dialog for selecting what to share is much better in the Adobe Connect 8: looks better, popups on top of current window(no need to click on taskbar), it is modal. I was wondering if it is possible to use this plugin from lccs(i.e. implement custom ScreenSharePublisher)?
Best Regards, Aleksey

+1 vote. We have the same need. We want to integrate ScreenSharePublisher seamlessly into our AIR app. The permissions dialog doesn't work for us. We would want the ability to customize.
We also need the ability to automatically share a specific rectangular area of the screen. The coordinates for this area is calculated by our app. Is there any way to do this with the ScreenSharePublisher API?
Thanks!
