Connection Hangs

Hi All,
Platform : Oracle - 10.1.0.4.0
OS - HP-UX B11.23
PeopleSoft -8.11 P1
From the People Soft logs we get an error;
12241/1 WRK:Init Remote Env Token
OCI0000141 - Error - ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
HPUX-ia64 Error: 2: No such file or directory
The connection hangs and we need to re-start the application to get back to normal.
But this error (0RA-27101) is not reported in database Alert Logs. The oracle is available when we access through sql*plus

Hi,
To resolve this issue with ORA-27101, you should be sure that ORACLE_HOME and ORACLE_SID are correct, and ORACLE_HOME should not have trailing slash.
The error will appear on the client side and not in the alert log.
Thanks

Connection hange while trying to connect via ssh.

Hi all,
I have this problem and i fixed it, just wanted to understand the logic behiend it.
I tried to login to a machine via ssh.
After providing the username and password, the connection hang until you press CTRL -C.
I checked DNS configuration, and some other stuff.
The problem was a NFS entry in the vfstab that was unreachable.
When i removed it, the connection went smoothlly.
My question is, why that entry caused that problem ?
Thanks!

At login, the shell runs 'quota -v' to display any over-quota conditions that might exist.
If the NFS mount was not mounted with "noquta", then it will send an RPC request to the server. If the server is down, that request will take 60 seconds to time out. If you have multiple mounts to the server, they might run sequentially.
The login should complete after a minute or so, but most users won't wait that long.

Connection hanging with java

Hello
we apply some simple Connection pool mechanism from our java code to Oracle
8.1.6. Due to some reason, oracle connections get hanging after a while. So
far I have not found out why :-(. The result is that whatever command they
are running at that moment gets blocked. This may be something so simple as
Connection.createStatement(). Result: my thread is blocked, the program is
blocked. Parts of it I solved by doing a test before delivering a connection
in a separate thread that gets a timeout. Not really elegant :-(. First,
when the connection gets corrupted in the code that uses it, I have no
access. And secondly, when the thread gets timed out, and the pool creates a
new connection, I still have this connection hanging ...
So, I hope that someone has some useful tips how should handle hanging
connections, and properly clean them. Meanwhile I will try to find the
reason of the hanging as well (maybe v$session or v$open_cursor has a clue).
Regards

You're right.
The Norton personal firewall does not handle localhost to localhost correctly. I do all the tests on the same machine. The netstat -an shows the port is listening in either case. But now I know the firewall blocks one of them silently. No rule prompt was triggered. Worse, no logging produced for that particular access.
Thanks. You've been very helpful.

[SOLVED] SSH, email - connection 'hangs'

Hello,
I have a problem with connections at work - it happens only at work, I tried on Arch and also Debian.
I haven't noticed it to affect 'web browsing' - it affects for sure ssh (incl. git) and sending email mesages.
What happens:
About 3/4 of times I try to send an email (google account from thunderbird), or log in to one of our servers with ssh (or pull/push some code from/to github) the connection 'hangs' and nothing happens. If I try ^C and 'redo' few times I finally manage to log in.
Log from ssh (unsuccessfull connection):

My /etc/ssh/ssh_config on Arch is default (everything commented out)
~/.ssh/config has only few Host, User, entries
On Debian:
/etc/ssh/ssh_config
Host *
SendEnv LANG LC_*
HashKnownHosts yes
GSSAPIAuthentication yes
GSSAPIDelegateCredentials no
Trying to ssh to server's IP doesn't change anything.
Any ideas how could I track where lies the problem? Or maybe I could at least make it 'retry' automatically?
Edit:
After setting timeout in ssh_config I get
Connection timed out during banner exchange
at the end of unsuccessfull connection.

I've set it already in ssh_config file (see my edit). Is there any way to make ssh 'retry' few times because now it gives up after first failure.
I've set ConnectionAttempts 5 but i'm not sure if it works - I'll have to give it another try on tuesday.

It is possible - however I don't know exactly how is the network 'distributed'. Maybe I'll try to change it at least at one server and give it a try.
Anyway - what about emails for example - this uses port 25 (smtp on gmail) and is experiencing the same problems (message sending lasts until timeout 8 out of 10 times).
I don't know too much about networks - maybe there is some kind of service which doesn't work properly in my network at the office. Any clues what could it be?
Most important for me is to make 'git pull' work - because it's executed automatically on those Debian boxes and if it fails they are not updated.
So solution like 'make it retry 10 times per 5 seconds' will do the job for 90% cases I think.

IPhone connections hangs when sending email after upgrade.

After upgrading to 2.0 firmware on my first generation IPhone, the phone now regulary hangs when sending email via smtp. Even if I try to close the connection by putting it into AirPlane mode and back again it still hangs and from that point onwards doesn't check or send any new emails. If I then shut the phone down and restart it looses the email as it's not either in the sent or outbox folders. This has happened quite a few times since upgrading. Does anybody have any advice?

Found this useful tidbit by mdwelsh231 on another thread:
"I'm having this problem too. Rather than rebooting the phone, an even easier solution is to hold down the Home button for several seconds (I believe it's 8 sec) which will kill the Mail application and return you to the home screen. Restarting Mail (by tapping the Mail icon) will cause it to reconnect. I find that this resolves the connection hanging issue. However, it is still kind of a pain. I suspect a bug in the 2.0 iPhone firmware. "
Worked for me
Cheers,

Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
Another thing to try - Go into your router security settings and change from WEP to WPA with AES.

JCO connections hanged in SMGW transaction at SAP

Hi ,
I have deployed an ear application in SAP WAS 7.0 which basically talks to my SAP backend using JCO 2.1 connectors. The application will fetch the data from SAP backend calling FM using JCO 2.1.
I m using JCO pool manager and set to default 100 connections and taken care of release connections after every RFC call in finally block. The connections released successfully in Dev and QA landscapes. In prod environment of customer, we are facing connections hang issues when it reaches to peak state of 100. It is due to max conversations reached at SAP backend, but the connections should eventually drop in SMGW which is not happening. There are some lost connections got hanged and remains for days and even they are not re-used. When i run method to release the pool, all connections are focibly returned back to pool, but lost connections still remain there.
Can somebody has similar situation ?
if connections reached to max in SMGW, will the connections from external client applications will get hanged ?
Does the JCO have control on the hanged connections if it reaches to max number?
Any help is appreciated!!!
Regards,
Ravi.

The relevant SAP note here is [549268|https://service.sap.com/sap/support/notes/549268].
But in this context there is big difference between the terms "not supported" and "does not work".
When SAP speaks of "not supported" this means that there won't be any SAP support for this configuration but this does not say anything about if this works technically. "Not supported" is more a legal issue than a technical one. SAP did not test this configuration and therefore also cannot guarantee to work.
Regarding JCo 2.1 I can say that technically it works with all Windows 32- and 64-bit versions. In contrast to that it really does not work with JRE releases >= 1.5 when using BCD types (type P) within your function modules.
From my point of view the connection issues don't have anything to do with the Windows version here.
And it is still not clear to me, if the maximum number of CPIC connections is reached at the AS ABAP/gateway side or the Java side. Furthermore it is not clear if these "hanging connections" were opened with your application at all or if they belong to another application.

Jdbc connection hang?

I used thin JDBC driver 9.0.1 comes with oracle 9i.
However, the connection hang in heavy load.
1. I try to check isClosed(), then reopen is more stable but problem is still exist.
2. It's more stable than 1. when do.. getConnection, do job and Close it. But another application connect more difficult get some error like 'not found oracle realm' or something.
Anybody has comment?
Thanks,

Hi to all and sorry for the delay of my reply.
I am not using RAC. After setting of the system property +"-Djava.security.egd=file:///dev/random"+ it has solved the +"Connection reset"+ problem, but after about one hour I get +"Connection closed"+ from each connection of the pool when the application uses it.
The pool uses the implicit cache mechanism of Oracle. Follow the properties of cache:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE properties SYSTEM "http://java.sun.com/dtd/properties.dtd">

Hi! I bought my Macbook Pro 13" in october last year but from last month oftenly my WiFi connection hangs up nd stops catching any available Wifi connection?
At last I restart the modem and dn it catches the signal but that too is short lived.

I have this problem on my home network but at the same time when my connection hangs up my other wifi machine remians connected. So i think there's no problem with the modem.

Why is my Internet connection hanging on both MacBook and Mac mini, but not PCs, Xbox, or iOS devices?

I have a MacBook pro and Mac mini both running the latest version of lion. I've had this issue with my MacBook for sometime now, but just dealt with it and figured it was isolated, but now I am finding its not.
Essentially, I will open up safari, or Chrome, and the first few pages will load fine. Sometimes I will get lucky and be able to browse normally, but after awhile, safari just hangs there and stops loading. I can close the window, and open a few more pages before it does it again. Both my mini and MacBook do this, but only on my home network. My MacBook runs perfectly fine on my work wi if, and other wi fis, so I definitely know its my home modem. If I wait it out I can surf the Internet again, but this dead time is absolutely killing me. It just randomly stalls, on both computers.
I current have time Warner cable roadrunner, with a cable modem gateway. The issue was happening on a straight connection. I had hoped getting a time capsule and connecting to that network would solve things, but it didn't. Interestingly enough, my Pcs, Xbox,and all 4 of my iPads and iPhones work just fine on the wifi, so there has to be a communication issues with the MacBook and mini with the cable router.
I've tried messing with lions network DNS servers and tried opendns ones, but those didn't work. Sometimes I can fix the problem for a few hours by power cycling the modem and router, but I shouldn't have to do that over and over every time it's an issue. I've also tried removing and adding the wi if connections, but that.works for a minute or two and then the problem resumes.
Now, I have my time capsule connected to the gateway, and tuned the time Warner modem wireless off, which didn't help of course, but at least I'm properly backed up.
I'm not sure what the issue is. I've even tried typing an ip address of apple during a dead time to see if that worked and didn't.
Does anyone have any other ideas? I'm pretty much at my wits end in this, any ideas would be greatly appreciated

Have you tried a simple reset of your iPod to see if that helps? To do this, press and hold both the Sleep/Wake and Home buttons together long enough for the Apple logo to appear.
Otherwise, have you tried any of the troubleshooting mentioned in this Apple support document?

Database connection Hangs - Urgent

Hello
I installed 9i db on one machine and I was able to connect from clients, then I installed 9ias on the same machine and now sqlplus hangs on the client when i try to connect. however tnsping is going thru.

JDBC Connection Hangs

I'm using the connection pooling system from Jakarta commons. My database access works fine most of the time, but for some reason sometimes the database hangs. I will try to access the web-app and the login screen will come up fine, but when I try to log in the app will just sit there trying to access the database forever, and from that point on no database access will work. Here is the code I use to get the connections and access the database. Is there anything I am doing wrong that could be causing this?

How do I do that, it doesn't even report an error. I could try sticking log traces all over the place, but it may not tell me anything about why the problem is happening.

Business View data foundation with dynamic data connection hangs

We are running Business Objects XI 3.0 with Crystal Reports 2008 and Business View Manager 12.0.0.683. In the Business View Manager tool, when I try to open a data foundation that uses the ACD Dynamic data connection, it hangs with the hourglass icon. I have left it trying to open for at least an hour before killing the Business View Manager with the Windows Task Manager. Data foundations using a static connection open fine as do the elements and views based on the data foundation with the dynamic connection. The static data connections included in the ACD Dynamic connector point back to an Oracle Server. Any ideas how to get the data foundations to open so I can edit our custom business views?
Thanks,
Kathy

I created some Views to pull the data in from the Oracle side.

Openning oracle connection hangs in aspx page

I have an application(on win2k) which connnects to oracle database(on Solaris machine).Application connects to DB & executes a simple query. As .NET application it works fine.

following is snipet of code:
string connString = "Provider=OraOLEDB.Oracle.1;DSN=ORAJOBINFO;system;manager";
OdbcCon = new OdbcConnection(connString);
OdbcCommand OdbcCom = new OdbcCommand(Query);
OdbcCom.Connection = OdbcCon;
OdbcCon.Open();
same code with DB2 DSN works fine.
can any one help me.

try using
OleDBConnection con=new OleDBConnection("provider=MSDAORA.1;user id=system;password=manager;data source=<<connectionstring>>");
con.Open();

Error 12545 on Connecting with sqlplus to Database. Remote connect hangs.

Hi there,
i'am new to Oracle.
After installing 11g on Windows 2008 x64 Server i had solved many Problems. But this Problem now i do not get fixed.
If i connect through SQLPlus local to DB it works. But if i connect on client (Win XP Service Pack 3) it hangs.

Ping and TNSping works fine.

Ok. Sorry, i solved this.
Set the local_listener helps:
alter system set local_listener='(ADDRESS=(PROTOCOL=TCP)(HOST=169.254.154.98)(PORT=1521))' sid='INDACO11';
Thanks!
