Urgent, please help-- connection does not close
Hi,
We are using Txdatasource, Oracle thin driver in WLS6.1 sp2. The problem we have
is that we open connection and pass the connection as parameter to third part
tool to generate report, but the tool doesn't close connection after finish, then
the connection is left never being closed, and our connections in connection pool
soon used up, have to restart weblogic to reset. the connection pool is set to
allow shrink, but those connections are not recycled. Please help, how do we somehow
set up WLS or database so that if a connection is not used for some time system
automatically close connection? Thank you very much. your help is greatly appreciated
Hi Chun,
I don't think it's possible whithout changing code. Primaryly it's because
it hard to tell whether connection is abandoned or still in use. So you have
to make changes in your code.

Hi,
Thanks for reply. The reporting tool is supposed to close connection butit didn't.
And now we need some quick fix on it without touching code.
Seems like the used connection can not be garbage collected because theconnection
I used yesterday is still not recycled today. ( I monitor JDBC in WebLogicConsole,
the "connections" column on "Monitoring" didn't change). No matter how bigI set
the maximum number of connections, the connections will use up finally andwe
have to restart WebLogic server.
Is there any way to make connection drop after some time?

What prevents you from closing connection after control is returned
back from the reporting tool?

they are GC-ed. Yet you should not relay on this feature as by the
moment a connection is closed the pool maybe already used up.
The other option I was thinking about is that it's possible to size
of the pool you use is too small for the application. Did you try to
increase (let say double) size of the pool?
FYI having shrinking and refresh enabled doesn't make much
sense in most of the cases. You can improve performance and
stability of your application by setting initial number of connections
to max and setting refresh period to let say 99999.
Hope this helps,

Wi-fi connection does not auto connect on 21.5-inch mid 2010 imac help?
Wi-fi connection does not auto connect on 21.5-inch mid 2010 imac running OS X 10.8.3 (12D78) help? My wife's imac with OS X 10.6.8 has no problem getting on wi-fi automatically as well as my Ipad 2 running iOS 6.1.2
If you get a green light then you did not do a factory reset - you must disconnect all wires and follow the instructions above - you will end up with the Extreme blinking yellow - then use the Airport utility to set up the Extreme - you can put in your own names for the network, device etc. - when it comes to the passwords you can use ones of your own choice - it is not asking for the old one - if it is then it was not reset completely - try to reset again if necessary - it may take more than one try - if it still asks for a password then use "public" - it is the default - once you have set it up with your new information, and you have a green light, test the connection with your computer - if you can access the internet then you are all set - then try to a use the Apple TV with the new password - if the computer still asks for a password, then it is asking for the computer password and not the extreme or network password - I can't help you with that - you would have to ask that question on the iMac discussion group.

Workflow 2.6.4.0.0 configuration problem - Command window does not close
I am trying to install Oracle Workflow 2.6.4.0.0. as part of Warehouse builder using the details mentioned in this link
http://www.oracle.com/technology/obe/10gr2_owb/owb10gr2_gs/owb/lesson4/etl-mappings.htm
From the Start menu click Programs > Oracle <Database HOME> > Configuration and Migration Tools >

However following this document, the command window did not close, and I did not get any message stating that Workflow Configuration has successfully completed.
The command window displays this message as the final step and does not close-

Is this installation complete? How to resolve this?
Please can any one help?
Thanks very much
AllanI ran into this problem. And it took me while to get it fixed, but It does work.
First the TNS Desc is misleading. One would think that it would be host:port:sid. What it is really looking for is host:port:servicename. But if you want to use the "Change Tablespace" drop down list you need to, enter the sys password, change it to host:port:sid - Then use the drop list. And change it back before you press submit.
The second thing that I found is that it wants to use the SYSTEM tablespace as temporary tablespace. THis is becuase it is looking for a temp tablespace called TEMP. If you look a the line default_temp = SYSTEM. And if you dont supply a tablespace it wanted to change it in the wfsysgnt.sql script in the $OH\wf\sql directory. You would think that what ever the default database tbs and temp tbs is - that owf would use that. No, it wanted to change it. Oracle needs to fix this.
So here is how i fixed it. I had to create a temporary tablespace called TEMP, does not need to be big as I dropped it after it was done. Then i had to modify the wfinstall.csh script and use the install options. Not the /tablespace this option is obayed but it will try to use the SYSTEM as the temp tbs. Here is my example that I appended:
/wfacct "owf_mgr" /wfpasswd "my_owf_mgr_pwd" /debug "true" /tnsConnDesc "my_host_ip:my_port:my_servicename" /syspasswd "change_on_install" /tablespace "OWF_TBS" -
FMS proxying HTTP does not close sockets correctly?
Hi,
So, after waiting for a while, we decided to upgrade our streamers to FMS 3.5.3 and set them up to proxy HTTP requests to a lighttpd server instead of the "built in" Apache. With the previous version 3.5 of FMS, we had problems of FMS hanging up after a while and stopping relaying requests, generally a few hours, even when it did not serve a lot of requests. With version 3.5.3, we had great hopes that this problem had disappeared as we had FMS running for more than a month on a test server. So we did the upgrade and we encounter another problem:
After less that one day of activity, our servers crashed for an unknown reason, almost at the same time. Analysing the logs, I saw out of memory messages, but how could two linux servers stop working in the same 5 minutes interval. I supposed there was a power failure of some sort. And I kept analysing because the sysadmins in the server room swore that they saw out of memory kernel panic on the consoles. After a bit of investigation, I found the reasons: the TCP connexions between FMS and the lighttpd server are stacking up and fill the OS network memory! Now, I don't know who is the culprit:
FMS code does not manage correctly HTTP proxy sessions?
lighttpd does not handle correctly HTTP proxying from FMS and does not close correctly the sessions?
Our Ubuntu linux network stack is not correctly configured to manage so many connexions?
Here are the details, any assistance is welcome!
The servers: linux Ubuntu 8.04 with 8 GB RAM.
FMS 3.5.3 proxying to lighttpd 1.4.19 listening on port 81. FMS and lighttpd are set up on the same server.
The streamer receives many (> 10/s) HTTP requests from iPhones which are proxied to lighttpd. iPhones request partial content and lighttpd is well suited for these type of requests.

The last red line can be visualised below; sometimes the server crashes in out of memory kernel panic...
And if you compare with previous behavior, you can tell when we did the upgrade to FMS 3.5.3...
A few words on our previous configuration with FMS 3.5. To be able to accept HTTP requests, we have a front load balancer which is able to route HTTP requests to lighttpd and RTMP requests to FMS. But with this configuration, we don't benefit from the ability of FMS to fallback to RTMPT for clients behind a proxy or proxy ol' HTTP requests... With the previous configuration, we never had so many connections active simultaneously: we change from 200 max to more than 7000 with FMS 3.5.3 in proxy!

I've tried changing lighttpd configuration to handle KeepAlive session or not, it has no influence on the behaviour.
If you spot a configuration mistake or have any idea, I'm ready to test it as soon as possible... Asa?
ThanksHas this been fixed? What was done?
We have been having the same issue. We worked on it with Adobe support and thought it might have been fixed with a "patched" version of FMS that was created to solve the problem. However, we still see the issue (recently we had a huge increase in load due to an annual event).
Over time, when we run netstat, we see Apache connections (127.0.0.1:88134) stuck in a FIN_WAIT_1 state while the corresponding FMS processes (127.0.0.1:1025 to 5000) are in an ESTABLISHED state. It appears as though the connection is closed from the http proxy side while FMS doesn't acknowledge the close.
We notice this behavior seems related to load. High load = connections getting hung more frequently. The only fix seems to be restarting the FMS service which restarts the embedded apache as well.
I'm curious if you found a fix or even a workaround to help you cope with these connections. Even something to close them periodically would be a huge help. So far, we're resorting to an automatic restart of the server ever 2 days which is hardly a proper production solution.
I would really appreciate any information you could provide with regards to your particular problem and whether or not it's been solved.
An example (just a snippet) of the netstat monitor we have running each hour on the half-hour:

This particular log shows all ports between 1024 and 5000 in the same state as above. A restart resets all the connections and the process starts over. From my investigation, Apache seems to be acting properly. It tries to be a 'good citizen' and issue a graceful close that goes unacknowledged by FMS. Unfortunately, Apache doesn't go back to check a connection it considers closed, so they connection remains half-closed.

Thank you for posting in Windows Server Forum.
Does that user able to login previously?
From your comment, it seems that there is some permission issue with that user. As you have checked that user with different system also. Please check that user is added under “Remote Desktop User” local group and also allowed “Allow log on through
Remote Desktop service” permission under group policy. Also please check that when user tries to login it uses “Domainname\Username” format.
In addition for a try, also check by disabling firewall on one particular system.
To add users and groups to the Remote Desktop Users group by using Local Users and Groups snap-in:
1. Click Start > Administrative Tools, Open Computer Management.
2. In the console tree, click the Local Users and Groups node.
3. In the details pane, double-click the Groups folder.
4. Double-click Remote Desktop Users, and then click
Add.
5. In the Select Users dialog box, click Locations to specify the search location.
6. Click Object Types to specify the types of objects you want to search for.
7. Type the name you want to add in the Enter the object names to select (examples) box.
8. Click Check Names.

Access DB (& .ldb file) does not close after crystal reports

Access DB (& .ldb file) does not close after crystal reports
Hi! We have a VB application using Crystal Reports 6 that has worked successfully on hundreds of systems for over 10 years. Now, on one network, the application and access database does not close. It seems to hang on the [.Close] command.
When we open the application an peruse the screens without opening up a report (using crystal reports), the application and access db closes fine. But as soon as we run a report and then close the report and try to close the application, the access db does not close. Many of the screens open the db and grab data from the access db, but it's only after running crystal reports that we have this problem. (Please see more information below.)
Setup: Application and data (access 97 db) reside on a server in the same folder, but application shortcut is kicked off on client PC. Kicking off the shortcut on the client PC means that the image/process runs on the client PC (not on the server). In this problem case, the application shortcut is on a Windows XP Pro Version 2002 SP2 PC with the app & data on a Windows 2003 server. Users are local Admins on their PCs with "Full Control"over the directory and files on the server where the data (access 97 db) resides. This type of setup is typical and has worked without any problems for clients.
The application is written in Visual Basic, using Crystal Reports 6 (using DAO). We close the recordset, set it to zero and then it hangs on closing the db (.Close command).
A few key pieces of information:
- The application closes fine if the app & data (access 97 db) are on a local PC. This includes closing fine if the application is run directly on the Windows 2003 server where the data is stored.
- It worked on this client's network until sometime in the last few weeks.
- One thing that changed is that the company is using VMWare on its servers. Not sure if they started using VMWare at the same time as it started failing. This may be unrelated. Possibly other things changed, but can't get any more information ... yet.
- It works fine running the application from a Windows Vista PC with a user who is a domain admin.
- The access db and application hang for about 10-20 minutes and then eventually closes. It appears that somehow
Crystal Reports is keeping the db open, but I'm not sure why.The application doesn't quit and the database doesn't close even if I try to end the task with the Task Manager.
- The Crystl32.ocx version being used is 8.0.0.4 (if that matters).
- I copied 6 month old program files and database files to a test folder on the Windows 2003 server. It fails using these files that worked fine 6 months ago.
Any ideas or help would be greatly appreciated! If you know of another good place to post this, please let me know.
Thanks!

You can probably work your way around this by doing Replace() calls on the relevant tags.

Date format Problem in OAF R12 Urgent Please help!!!
We have acustom application in OAF which was developed in 11i. Now we migrated the same to R12.
In this there are two date fileds getting dispayed on the page and the query for the same is
SELECT TO_CHAR (SYSDATE, 'dd-mm-yyyy') AS CURRENT_DATE, UPPER (TO_CHAR (SYSDATE - 10, 'mon-yy')) AS g_period, UPPER (TO_CHAR (SYSDATE + 5, 'mon-yy')) AS gnext_period, TO_CHAR (sysdate,'dd-mon-yyyy') as today_date, TO_CHAR (sysdate - 1,'dd-mon-yyyy') as yesterday_date FROM DUAL
In 11i version the output is dispaying correctly but in R12 the current date is dispayed as
Start Date 04-Nov-5242
End Date 04-Nov-5241
As per logic it should be
Start Date 09-Feb-2012
End Date 10-Feb-2012
Please help..Urgent issue.Here are the answers to your problems :
1. Once u restart , the oracle services and the database is not mounting automatically.That is because, when you install the Oracle Oracle8i Standard Edition Release (8.1.7), the two key services namely
OracleOraHome81TNSListner and
OracleService<your SID name>
are configured as manual start ( check the NT --> start>setting>control panel>services. )
For the database to start automatically the next time you start your machine, these two services will have to be put into "Automatic Start" mode.
< for this double click on the respective service, select the "Automatic" radio button and click on ok>.
Now when you restart the machine, your database will be automatically mounted.
2. this as explained above is a corollory to the above problem. you can start or stop your database on NT using the "Services" window....
hope this helps.
bye.

Asha 311 radio application does not close.
The radio application in my asha 311 does not close. I tried using the back button first, but when I swiped the screen the radio showed up so I used the end call button and then it showed "Radio Off". But then again when I swiped to check whether the radio has closed, the radio came up once again. I tried switching off the mobile and turning it on. That didn't help either. Tried connecting, disconnecting the headsets and i still have the radio open. I am unable to close it. Any suggestions?
Its only a week since I bought the Nokia Asha 311 and this is the first ever problem that I am facing.
Solved!
Go to Solution.Hey, its nothing wrong. You've added shortcut to radio on the swipe screen. That's why it shows you the radio screen
change the shortcut to something else (dialler) and that's it -
When I exit Reader for PC it does not close completely, causing an error when I try to "safely remove hardware".
I have to use Task Manager to close the process; the application is not shown as running.
I believe this has happened only since the recent software update. Is there a way to get the previous version?
ETA:
This only happens if the the reader (T1) is connected. Software closes properly otherwise.Hello,

Internet via WiFi works, however, hard wired connection does not work.
My software indicates my hardware is working properly.
However, if I connect another computer to the cable I am using, it connects to the internet without a problem.
And, if I connect my comupter to another cable that works with another computer, my computer still does not connect to the internet.

I think in any case the case will have to come off and someone look for physical/connection problems. It doesn't sound like a software problem but there is always a chance.
