Maximum no. of Connections?

I am attempting to open 250+ connections using jdk1.1.7 and classes111.zip(solaris 8052) connecting to an 8.0.5 database. After opening around 230 connections ORA 12505 is encountered. From the TNS logs it appears that the SID being passed has been corrupted. The database has been configured to allow 1000+ connections. If I run two instances of the same process both are able to get 230+ connections but both fail at the same point.
Is it realistic to wish to open this many connections in a single process, if so, does anyone know how I can resolve this problem?
The maximum number of files each process can have open has been increased to 1024 and I have changed the stack/heap sizes by using -mx -oss and -ss.
/usr/local/jdk1.1.7/bin/sparc/green_threads is also being used.
Thanks in advance.

The problem it exceeded the man. no of file
descriptors allowed.
Please see the FAQ for more details. Each
connection may consume 3-4 fds depending
upon the configuration and hence this
problem.
Also, it is not realistic to open so many
connections. Go for connection Pooling

Hi virajkumar
Please bear in mind two processes involved here, OVI Maps application which may either be "Online" or "Offline" (spanner icon > Internet > Connection) and Assisted GPS feature utilizing a network access point (Menu > Applications > Location > Positioning > Positioning server > Access point).

E66 - "Maximum number of connections in use. Clos...

When I try to use the web or Google Maps I get an error message: "Maximum number of connections in use. Close an active connection first."
I suspect it's related to having a connection going for automatic email but I did not have this message on my N78 or my 6120 classic. I suspect it's NOT related to my service provider since it works fine with the other phones.
The window that lets you close the active connections only has one to close. It crashes Google Maps pretty hard too.
I've got the e66-2 (NAM version) I don't know if that makes a difference. Any firmware upgrade for the e66-2 yet?
Any workaround ideas?

Try quitting the active connection and starting a connection on Google Maps first, the next time. This is not abnormal. And are you sure that you used the same provider and were able to do the same thing without closing connections in the other devices ? In my experience, this is network related.

Maximum number of connections in use?! -E71

Hi, I have this problem when I try to connect to the internet through any program. Before you rush to reply, I WANT to have multiple programs using the internet at the same time. I find it completely idiotic having to close Nokia Messaging to open my web browser. I want to be able to run Nimbuzz while running Nokia Messaging (example). Funny thing is, if I select OK when it asks me to close a connection, and then just cancel, everything works ok!! Well, for a while, and then the message pops up again.
Come on Nokia, it's just a simple solution, how hard can it be?
PS. Using E71 with the latest firmware (200)

You can use multiple applications using the internet at any time but ONLY one access point can be in use.
you cant be connected with more then one access point therefore if the different applications is set up to use different access points then you will have the maximum number of connection issues.
Just like the Computer if you are connected to the internet and you connect your phone as a modem the connection from your phone will overwrite the connection and be the default connection.
You may change the settings in the individual applications in the options > settings (may vary from applications)

Nokia N8-00 'maximum number of connections in use'

Hi,
I have creted another APN in the Destinations-Internet settings. Put this APN on priority 1. Then I se internet an it is ok. But when I open Nokia Maps or another App. Sometimes it tries to connect to the old APN then says 'maximum number of connections in use'. Asking me for confirmation to close one connection.
So I move all APN's and Wireless connections out of the Destination Internet. Except for the new on that I want. Still the same message From time to time. How to stop thi message. Deleting an APN is not a solution I am looking for otherwise I would have done that.
Any help is appreciated.

So the on off method I posted earlier did not work. The first APN is still tring to be accessed by some apps after the phone is switched off and on again. The other things I tried..
- Removed the APN restriction and renamed the first APN. When I start the APP it now gives me a warning and lets me choose the APN. I choose the second one so greate. Close the APP. Now when I rename the fisr APN to the original name. APPS try to access it again and I get that original error.
The only thing I could do is configure the first APN name with the actual Access Point of the second APN. This worked All apps are accessing the first APN whaich was reconfigured to look like the new Second APN.
This is not a solution again it is a workaround. Does anyone-else have this problem. Or am I the only one who is configuring multiple APNs. Since my provider has multiple APNs.
I would have thought that this phone supports Multiple PDP contexts, or Secondary PDP context. It was defined in the initial 3GPP specs way back in 2003ish. Nokia can you confirm???
Cheers Peps!

Nokia E90 - Maximum number of connections in use e...

I invariably get the error - Maximum number of connections in use. Please close open connection - (this is not the exact verbiage of the message) when i connect to the gprs / wap. this started occuring after i updated my firmware from 200.x.x to 210.34.75.
The funniest part is that the application would connect to wap / gprs if i select cancel and ignore the message and continue.
If i select Yes, then i will be forced to close at least one application which is connected to the wap / gprs
I have different access points configured for each application and hence i see no reason for this error message.
Also, i never had this issue with this phone before, when i was using the same setup; separate access points for the applications which use gprs / wap.
Please advice as to how i can get rid of this message popping up every time i use wap / gprs.
Please help....
Also are there any good navigation softwares with Maps for India available, so that i can use it on my E90 and N82.

Every time you up-date the firmware, you get from your network opperator the settings for various access points (Internet, MMS, Vodafone Live, whatever....) This leads to duplicates (or even mode) access-points. Moreover, some of these access points are saved as "default" access point in various applications. This is where the mess starts.
To clean-up the mess, you first have to REMOVE all duplicate access points and keep only one access point for each purpose: Internet connection, MMS, Live (if you are are on Vodafone), etc. After this, you will probably get messages from various applications to define a new default access point. And things will be sorted our automatically.
Hope this helps, even though it might not be simple for some.

Ora-00020 maximum no .of connections exceeded

Hi All,
I tried to connect the production Db is says Maximum number of connections exceeded.
How to overcome this situation.
I stoppped and bounced the Db.
The process paramter in pfile is 50
Is there any to overcome this

c:\sql>oerr ora 00020
00020, 00000, "maximum number of processes (%s) exceeded"
*Cause: All process state objects are in use.
*Action: Increase the value of the PROCESSES initialization parameter.
Increasing the PROCESSES parameter as suggested by the error information would remove the issue.
If the database has been working fine for an extending period of time without this error you should consider finding out what caused the increase so you can set parameter appropriately. Could be an increase in use or an application leaking connections.

Exception:exceeded the configured maximum no of connection!!!!

Folks
I need some urgent help please,
I have developed an application that sends messages in XML Format to the
Server and the server sends a response back.
A new request is sent by the client as soon as it receives a response from the
client
So if I sends Request A ,I get a response back for request A.
Then I send Request B,I get a response back for request B
No suddenly while sending Request C the system halted.
On checking the Error I encountered a strange IO Exception thrown
'Java.io.IOException:exceeded the configured maximum number of connections"
Please can anyone tell me what this means?
I have an HTTPWriter class that invokes the Server
public void sendRequest(byte[] str) {
try {
urlConnect(url,str);
}catch(IOException e) {
String eIs = e.toString();
Registry.getAlertError("Connection Error", eIS);
Where eIS is the error message described above.
Please can some suggest what shud i do? This is extremely urgent folks.
An honest response is much appreciated

I am closing each connection in the finally clause
What shud I do?Re-examine your code to verify that each is being closed.

Maximum number of connections for MS Access with JDBC

Hi guys,
does anyone know about the maximum no. of connections that MS Access can have with JDBC...

MS Access has not limit. It doesn't work that way.
There is certainly going to be some resource limit however, if nothing else then memory will eventually run out.

Why do I keep getting the message "Unable to connect to Imap server you may have exceeded the maximum number of connections to this server.

I already tried reducing the maximum number of connections to 1, but I'm still receiving the message. Is there anything else I can do?
My computer is a Mac mini running OSX 10.9.5. Firefox is version 34.0.5.

Ok, IMAP server almost universally allow multiple connections. Thunderbird as you would have observed uses 5 if they are available. As Airmail suggested, iphones just use more and more until they exhaust the available connections. There is no set maximum option.
However there are other things that can consume connections and some may surprise you.
Anti spam tools such as mail washer
Anti virus programs in their anti spam or anti phishing roles
Web mail.

That is from the top of my head. So could any of those apply.

Problem with reached maximum number of connections to database

Dear Experts,
Our Production system was not responding properly last week.
The below was the reply from the Basis team.
"It seems that we have again problem with reached maximum number of connections to database. We have extended this number to 100 this year and now it seems that it’s not enough again. It seems that something is running on Production, which takes over too many connections."
They have increased the number to 200 as a work around.
Do we have any means to find out, which component or application is causing the issue.
Please advise me if any better way is available to correct the issue.
Please see the below trace.
