Maximum Connections Oracle can provide

I have this query, how many maximum connections does oracle provide to any applications server.
I am aware that the number of connections are configurable. But i wanted to know the maximum number of connections after which there is a possibilty of oracle to crash, or after these particular number connectins oracle wont support any more connections.
Please help me with this, as im in desperate need of a solution.
Thanx for your time.
Nikhil

There is no functional limit to the number of connections Oracle can support. There may be some internal limit (i.e. session ID may be an integer, which would limit you to 4 billion connections on a 32-bit system) but I've never heard of anyone actually hitting such a limit. In reality, you will be constrained by your hardware long before you are constrained by Oracle.
Unfortunately, estimating how many connections your particular hardware can support is not trivial. It depends, obviously, on your hardware, but it also depends on your application and on how your database is configured-- shared server vs. dedicated server would be the largest factor here.

Oracle connect failed on x64 and IA64 platform via Oracle OLEDB provider

Hi everyone,
I installed SQL Sever on x64 and IA64 machine, and Create a database via Oracle datasource. I can connect the datasource via OLEDB and .Net provider successfully on x86 machine. But failed to connect the Oracle datasource on x64 and IA64.
Following is the error messgae:
1) Install 64 bit build on x64 machine:
Error message: Test connection failed because of an error in initializing provider. ORA-06413: Connection not open.
2) Install 32 bit build on x64 machine:
Error message: Test connection failed because of an error in initializing provider. Oracle client and networking components were not found. These components are supplied by Oracle Corporation and are part of the Oracle Version 7.3.3 or later client software installation.
I know there is a know bug on c:\Program Files (x86)\... with Oracle provider. And some one has given a workarround method that I should move my my application out of the the folder path which includes parentheses. But it really is mess method for SQL Server (That is my application)......
Is there any other workarround method? Or when will Oracle fix this bug?
Thanks^_^
Lindsay

Is 10204 available for x64 and IA64. It is said that there is only 10204 for x86 machine, right?
I downloaded 10203 for IA64 machine and tested connection on SQL Server with Oracle datasource via Oracle OLEDB provider, and got the following error (The data source is Oracle92 installed on another machine):
Test connection failed because of an error in initializing provider. Oracle client and networking components were not found. These components are supplied by Oracle Corporation and are part of the Oracle Version 7.3.3 or later client software installation.
Could you please tell me what's wrong with it?
Thanks
Lindsay

open p_curser for select * from table_name;
end;
please help me asap.

I tried it, commented out the reader.read and have the following connection string
string connectionString = "provider=ORAOLEDB.ORACLE; data source=ORCL; password=****; user id=****; OLEDB.NET=True"
Unfortunately the result is the same.

My i phone 4 fell down and I can't connect to my provider.it also recharges itself within a few minutes and the back of the phone is really hot.what should i do?

my i phone 4 fell down and I can't connect to my provider.it also recharges itself within a few minutes and the back of the phone is really hot. I tried to send it to the technical support but they told my that the reparationcosts will be higher than the actual price of a new phone.is this possible?

Yes, it is entirely possible.
Although in most countries Apple offers an out of warranty replacement for a nominal fee. In the US it is $199 for the 4S and $149 for older generations of the iPhone. Depending on where you are, that may be an option.

I can't connect Oracle 7.3.2.1.0 by sqlplus anymore!

Hi!
I have an Oracle 7.3.2 for Irix installed before.
When I install Oracle 8.0.5 for Linux without Pro*C,
I can connect Oracle 7.3.2 by "sqlplus scott/tiger@remote".
But if I include Pro*C installed, I can't connect Oracle
7.3.2 by the same command anymore.
What should I do to solve this problem?
I can compile Pro*C program but get the same response :
ORA-01017: invalid username/password; logon denied
password is right for sure, server just doesn't accept.
null

My problem is a little different from your. I have both
Oracle 7.3.2 and 8.0.4 on our Sun workstation. I can connect
to Oracle 8.0.4 using both sqlplus and embeded SQL. However,
I could not connect to Oracle 7.3.2 by sqlplus or embeded SQL.
Error Message: ORA-12545: Connect failed because target host
or object does not exist
It's is a bug or it's not support to connect to old Oracle
Version??? If anyone have a solution please let me know.

Connection kit (USB Camera adpter) Maximum memory iPad can handle?

I had a iPad mini and I'm not sure about the USB Camera adapter or SD Card camera adapter can support how much the external hard drive memory? Are these things can support a maximum of 32GB more or less?

The camera connection kit can only be used to import photo/video files from a camera, SD card or USB flash drive. You can't import other types of files. You can't export any type of files using the camera connection kit. ie, It's not an external hard drive.

Can't connect to wifi provider 3G

When i come home the iphone 5 finds my wifi and connect to it. In 2 minutes he will lose his connection and can't connect to my wifi anymore ( 3 bars ! ).
Even if i turn my phone off and on........... NOTHING !
My provider and the 3G is dropping to and lost sometimes
Other people seems to have the same problems...
I hate the last IOS8 because from that date i got nothing but troubles ! Even with the update !
Please set everything back to IOS7 !
I hate this !! >

I live 3 hours out of Brisbane.. I was in Brisbane on business and was advised by the Telstra shop that if I bought my phone there, and I had a problem with it, there would be no problem for me to take it back to the Telstra shop in my home town. This was not the case. The Telstra shop in my home town advised me that I would have to take the phone back to the place of purchase. In effect... I was lied to by the Telstra Salesperson in Brisbane.
When I spoke to my "offshore" customer service provider, she also confimed that I would need to take the phone back to my original place of purchase.
I have been periodically testing to see if the 3G will work (as also advised by Miss. I live overseas) and this morning at 7am, it worked.
My concern now is... will it keep working? And why does my husband's Telstra iPhone work fine.... my daughter in laws Telstra iPhone work fine.... my best friend's Telstra iPhone work fine.
I guess maybe I should have listened to my son and gone with Optus.

Looks like we are running out of the maximum connections IAS 6.0 SP4 can open with the database. Where is the setting and how can we change it?

We are using IAS 6 SP4. We have 4 kjs engines and we see total 112 jre threads being spawned to database. The code is not able to open connection with the database when we go beyond 60 users (approx)
Any clues?
Thanks in advnace

Hi,
Fine,Its always better to increase the Max pool Size settings to a large value corresponding to KJS's max thread value. Sometimes i had faced problems with Asynchronous database queries eventhough i increased the Max thread value of the Driver to a good maximum value.
If an application has a very large number of users who access the same data, then Setting the Database Cache's Maximum Connections to a large value will surely help.
I think its always better to have a clear database connection settings strategy ,considering your Complexity of your Application 'We are using IAS 6 SP4. We have 4 kjs engines and we see total 112 jre threads being spawned to database'.

Sql * plus 9 is not able to connect oracle 7 database

Today I have installed oracle 9i release 2 and found that the sql * plus provided with is unable to connect oracle database version 7. But before that we were able to connect the oracle 7 database well.
Any one having a clue on that...?
Is it a product bug...?
If so then please provide me some alternative solution clue or patch download link. Please remember in any condition currently it is not possible discard my oracle 7 database.
With Regards.
Soumen.

No, it is not a bug. You just cannot connect with Ora9i R2 SQL*Plus to an Ora7 database.You cannot create a DB link between the two database either, if you are planning on doing that.
A solution is to install Ora8 client, which can connect to both Ora9 and Ora7 database (but a db link will stil be impossible).

Oracle Data Provider (ODP) Passing Arrays to PL/SQL

Does anyone know how to pass an array or collection of data (from VB.net) to PL/SQL using the new Oracle Data Provider?
My PL/SQL procedure is accepting type Table (Table array).
This was easily done with Oracle Objects (in VB6) but I've found no way to do this with the new provider with .Net.
It seems like a serious limitation if it can't be done.
Anyones help would be appreciated.

Just out of interest, what are the performance implications of using REF CURSORS for retrieving resultsets from Oracle stored procedures via ODP.NET?
When coding the PL/SQL for these, the REF CURSOR is left OPEN and not explicitly CLOSED. When does the cursor actualy get closed? Is there a risk of reaching "maximum open cursors" or some other limit more quickly if REF CURSORS are used in this manner?
I haven't found any documentation of this issue as yet.

Oracle OLEDB PRovider with ASP

hi,
Can anyone provide me a piece of code which demonstrates how to call an Oracle sp from asp using the Oracle OLEDB provider.
I would also appreciate if the Oracle package code could be provided too, since with the Provider we have to have a different code for the stored procedure (Ref cursor..??)
I have been successfully connecting using the Microsoft ODBC Driver, but looks like it has some big time bugs in it which causes our server to hang and a dllhost.exe to consume large amounts of database memory.
Anybody can help me with that?
Many Thanks,
Harshad.

Harshad,
Oracle OLEDB samples are available at
http://otn.oracle.com/sample_code/tech/windows/ole_db/content.html
URL.
"Returning multiple recordsets from a stored procedure" sample demonstrates
how REF cursors are returned from a Stored Procedure (contained in a DB package).
This sample is a stand alone application and not an ASP program, but the same code
can be helpful for ASP too.

Jagriti
