JDBC Sessions Are Left Open

I am having a problem where the JDBC sessions are not being closed. We are using the NCR Teradata JDBC driver talking to a Teradata Data warehouse. I am not aware of any way to explicitly close the JDBC sessions using JDeveloper, since I dont directly issue any JDBC statements for selecting data. Is there a way for me to close the sessions in code?

The following is the Data Source that I am using:
<?xml version = '1.0' encoding = 'windows-1252'?>
<!DOCTYPE data-sources PUBLIC "Orion data-sources" "http://xmlns.oracle.com/ias/dtds/data-sources.dtd">
<data-sources>
<data-source
name="jdev-connection-Teradata"
class="com.evermind.sql.DriverManagerDataSource"
location="jdbc/TeradataCoreDS"
xa-location="jdbc/xa/TeradataXADS"
ejb-location="jdbc/TeradataDS"
pooled-location="jdbc/TeradataPooledDS"
connection-driver="com.ncr.teradata.TeraDriver"
username="GavinLDCHBull"
password="xxxxxx"
url="jdbc:teradata://FONEBONE/DATABASE=HABWaiver"
inactivity-timeout="30">
</data-source>
</data-sources>
We are using the ADF framework (i.e. entities and simple views) for accessing all Teradata data. I do not explicitly issue any JDBC calls for accessing the data. When I update the data, I use JDBC calls to initiate stored procedures. However, the problem (not closing the statements) happens almost immediately after starting the application, and prior to issuing any stored procedures.
I have not tried to duplicate the problem using a simple java program because I am using ADF for data access (again, I don't explicitly issue any JDBC statements).

Slow after sleep if windows are left open?

So my mac is only a few months old but it's been having this odd problem for the last month or so. If it goes to sleep (either through shuttiing the lid or not touching it for however many minutes) it will be extremely slow for the first 10 minutes or so after I turn it back on, but then it will eventually come back to its full functionality. However, this only happens if I leave a window(s) open when it goes to sleep. It doesn't matter if it's itunes, safari, or anything else. Also, if it's playing music but I don't touch it for a while and the display goes black it'll be fine until I try to use the computer again, then all of a sudden the music starts lagging. So what can I do to fix this? I've already gone through all the steps of the "10 ways to speed up a slow mac" etc. The mac in general isn't slow, it's only when I leave windows open and put it to sleep.

Dear Ruud,
thank you so much for your post on our webforum. I noticed that this is a known issue for Labview 8.6, a while ago it was reported with a Corrective Action Request (CAR# 132471). The issue should be resolved with Labview 2009. I wasn't able to reproduce the issue wit Labview 2010, the number of handles stayed arround 28000,

Multiple session are open thought Users log out.

Hello Gurus,
I do see at CMC that many sessions are being open for many days even though users are logged out.
We are using SAP 4.0 (14.0.4) SP4. It's causing license issues and users are not able to log in.
We have restarted our VM's and clear the IE browsers as well but issue still remains.
Can you please help me on this.
Best Regards,
Sai

Hi Sai,
Could you give more information about BOE products you use and for which datasource type (UNV, UNX ?).
I know SP04 still had different issues where multiple sessions were created when working on UNX Universes (see https://support.wdf.sap.corp/sap/support/notes/1764372), and it could lead to "lost sessions". There are other similar problems fixed in more recent versions of BOE, so you may think about upgrading your platform at some point to benefit from all these corrections.

Loic

Message "session is already open.." even if all other Imac are off!

Hi,
Message at the login window of the user computer: "session is already open on another computer.."
user can not login even if all other computers are off.
I rebooted the server, no change!
What is wrong?
Thanks,

Fatal bug with shared JDBC Session Persistence

We are attempting to launch a three-tier site with two clusters, one at the
          web layer (JSP/servlet/images) and a separate cluster at the app server
          layer (EJBs). We are running WebLogic server 4.5.1 Service Pack 8 on Solaris
          2.7. In production we use Solaris JDK 1.2.1.04, and in development we use
          JavaSoft JDK 1.2.2. We are able to duplicate this problem with both JDKs. We
          are using the WebLogic kona/oracle driver for session persistence because
          the Oracle JDBC driver would not work for this purpose - we are using the
          Oracle OCI driver for our EJB persistence in a separate pool in the app
          server cluster.
          We attempted to configure our web cluster to work with in-memory session
          replication. We found the performance of the WebLogic proxy to be abysmal -
          causing a 5x to 10x performance degredation over shared JDBC persistence. We
          were running the proxy on WebLogic, which we were advised would be slow. Its
          performance is beyond slow, it is completely unusable and should NEVER be a
          recommended or even supported configuration. We do not wish to purchase
          separate licenses for iPlanet, refuse to run IIS in a production setting,
          and cannot use Apache until WebLogic 5.1, so we are stuck with shared JDBC
          persistence until we can upgrade to 5.1.
          Using JDBC session persistence with a shared persistent store amongst all
          the clustered web servers results in our users getting brand-new sessions
          populated with data from OTHER USERS' SESSIONS. This is very easy to
          replicate using the provided test JSP and java class. This behavior results
          in new users coming to the site and finding themselves logged in as other
          users.
          The test.jsp file simply accesses the session, prints out some information,
          and then adds a few values to the session. The JSP prints out the value of
          session.isNew(), the session's ID, and the number of values in the session
          space. If you hit this jsp with a new browser window, the session should be
          new, and the number of values should be zero.
          The test Java class hits a URL with this test.jsp file repeatedly, and
          checks to make sure that the session is empty. It keeps a counter of the
          number of hits which resulted in non-empty sessions and the total number of
          hits. Because this java class does not maintain cookie data of any kind and
          merely opens new HTTP connections, it should always receive a brand-new,
          non-empty session.
          When we set the JDBC session persistence property
          weblogic.httpd.session.persistentStoreShared=true and run the test, we see
          periodically see the test.jsp file receiving a brand-new (session.isNew() =
          true), yet non-empty (session.getValueNames().length != 0) session. This is
          extremely bad behavior and makes the shared JDBC session persistence setting
          worthless. We were able to duplicate this behavior with both a single server
          and multiple servers in a cluster.
          If we set weblogic.httpd.session.persistentStoreShared=false, then this test
          works fine. This also means that we cannot cluster web servers.
          To run the test, simply start a WebLogic instance using the provided
          properties file, put the jsp in the document-root somewhere, and then run
          SessionTest.java, providing the URL of the test JSP as the only command-line
          argument. You will need to modify the properties file to have the proper
          database settings and document-root. The java class will display a running
          tally of the number of hits, and the number of hits that result in
          non-empty, illegal sessions, with a total at the end.
          So, we are now in a position where we are completely unable to launch our
          site in a clustered, no-single-point-of-failure configuration. Obviously,
          clustering was one of the main reasons to choose WebLogic, and we are
          extremely distressed that we are unable to get this configuration to work.
          Any help would be appreciated.

I hope this is not too far fetched, but we are expieriencing a similar
          problem with jms (messages are mixed up between queues). This happens only
          if we are using message persistence in an oracle db (everything works ok
          when we are not using persistent messages). Could it be that there is a
          serious bug in the jdbc code/oracle driver code or connection handling
          (regarding multi threading)? This would explain that, whenever you use
          persistence with oracle databases, messages/sessions (or other) are mixed
          up.

One of the users on my Mac book pro, running Mountain lion finds that no changes made in last session are there next time they log on

One of the users on my Mac book pro running mountain lion finds that no changes made in last session are there next time they log on.
For instance, the Macintosh HD icon, is always moved so that it is almost off the screen to top left hand side of the desktop.
None of my changes to the sidebar in the finder are there.
My changes to the dock have reverted.
Despite unticking the box when logging out, even though i have quit all applications, iphoto and safari are always re-opened.
iphoto always says the library needs to be upgraded... even though i did that the last time.
I have tried deleting ALL the files in the "Saved application state" folder in the library folder, but that doesn't seem to make any difference.
This is on a second admin user account.
The main user account seems to be fine.
This account used to be in the filevault on Lion, but is not now in Mountain Lion.
Can anyone help?
Thanks

The same tragic thing happened to me, not even a full two days after I bought it. I immediately powered it off, wiped it as best I could, and put it in front of a fan. I tried valiantly to get the back off, but couldn't remove all the screws. I was basically inconsolable until I realized that no matter what, my credit card insurance would cover it, since it had been less than 90 days. Fast forward 48 hours, and it seemed to run just fine. Some of the keys and the track pad were sticky, and I figured since it was covered, I might as well get it fixed. My only concern at this point was had I voided the Apple Care. I brought it in, told them what happened, said what I needed to satisfy the credit card, and they said, "We'll just swap it out for you, no problem." I was thrilled, and the Genius said they appreciated my honesty, and it was easier for all parties to just do it this way. And my Apple Care was transferred to the new machine. This was my first Mac and, needless to say, I am now an Apple devotee.

Photoshop CS4 "Could not save as...because file is already in use or was left open"

I have been using Photoshop for years, and CS4 for about a year now. I have never had this error message pop up until this week. It started happening right after I did the Adobe update to 11.0.2. Everytime I try to save a PSD or JPG file now (which are the only two types of files I work with), I get this message preventing me from being able to save;
"Could not save as... because file is already in use or was left open."
I have to attempt to Save as about a dozen times before it will finally save the file. Any suggestions on what could be wrong and how to remedy it? Is it the update that caused this problem?

Turn off Caching of Thumbnails in Hidden thumbs.db Files
People sometimes report that they cannot manipulate their folders as they want to because Explorer has a thumbs.db file open. Windows 7 apparently generates these files for compatibility with older software that may expect such files to exist in folders with, for example, photos in them.
The good news is that (with Windows 7 Professional and above) you can disable this through the Group Policy editor:
Click the Start orb
Enter gpedit.msc in the search box and hit Enter.
Expand User Configuration - Administrative Templates - Windows Components.
Click on Windows Explorer.
Right-click the entry "Turn off the caching of thumbnails in hidden thumbs.db files" and choose Edit.
Enable the setting.

Could not save *.* because file is in use or was left open...

OK, I mentioned this when it happened with .eps files, and rather than get a single useful tip(Except for 'choose a new file name'), I got a series of responses from people telling me how I should be saving in .tiff and 'eps files aren't any good anyway, etc., etc... IN other words, no help, just a bunch of opinions on what I was doing wrong in the first place.
Well, now I have had it happen with a .tiff file. I opened the file, did some work, and went to re-save it, and I got the error that it could not save the file because it was in use, or had been left open.
Anybody got any suggestions on why this is happening?

Could not save because file was already in use or left open

I am have several problems with Adobe Photoshop CS4. I call up Adobe for help, I pay 50.00 or 60.00 for their help with these situations that I am having. Adobe concludes the phone call saying they are closing the case cause the problem has been resolved. I told them it has not been resolved I am still having problems then the person hangs up on me. I call back cause the problems still persists, the tech person told me that I had to pay another 50.00-60.00 for the
tech support. I told him that I already paid and that I still need help, the tech guy told me that the case was closed cause it was resolved. I told them it was not
resolved and I am needing help with this particular issue. The tech person kept saying that the issue was resolved and if I needed more help that I had to pay.
This time I hung up on him and while I did that I said that the Apple Support Community was way more helpful and it was free.
So here I am 6 months later and tried everything, Here are the problems that I am having.
1. CS4 keeps quitting unexpectedly with no cause no error nothing. The blue light under the CS4 Ps is still lit and wont let me reopen the file, I then have to force quit the program. I then get these windows asking if I want to send a report, I click ignore cause I am tired of filling out those things. So I try to open the
photoshop file and I get the blue window with the Ps logo on it, its scanning everything but then it stops responding when the scan reaches the part where it says scanning memory and freezes. I then have to force quit the program again, I have to do this 5 times before it will open the file. Then Ps will unexpectedly quit after 2 hrs of working and starts the B.S. all over again. I dont know what is wrong with CS4. Other times it runs really slow and glitchy. It also happens on my Mac Book Pro, iMac and of course my Mac Pro.
I know its not the computers or the settings or anything interacting with it. I checked everything extensively from the terminal to permissions and back to the program itself and everything in between. I am needing help, the Adobe forums are of no use, I cant find anything there.
2. I keep getting this error and I am not sure what it is, this only happens when I use Ps CS4 and yes it happens on all my other Apple computers.
Error: "could not save because file was already in use or left open" not sure how to fixt this, I have already tried the permissions and it did not seem to work.
All my computers run OS X Lion version 10.7.3. I had these problems even before I upgraded to Lion, 2 months later after Lion came out. These problems have been going on since Snow Leopard. All my Macs are up to date and I did use the Disk Utilities on everything... Please help me.

First off are you editing a photo that you have placed into indesign if so the in use or left open issue is a common one, the only help is to go to indesign move the picture by nugging it then go back to photoshop and try saving again, if this does not work close the indesign file then save.
On the other issue of photoshop crashing, One thing I would try would be to create another user account, Start up photoshop and only it and work with it. The reason why is to see if maybe there are some 3rd party software you have loaded on your systems that might be causing the issues. "Ya never know"
I would assume you have reinstalled photoshop on lion. Do you still have older version of OSX installed, if so try booting to them and working with photoshop to see if it works there.
Good Luck

Could not save my_file.psd because the file is already in use or was left open by another app"

Since some time ago I often get this message when trying to save my PSD file: "could not save my_file.psd because the file is already in use or was left open by another application", whereas there's no application that uses the file in reality. What could cause this problem?

What could cause this problem?
If I remember correctly posibilities include the OS, anti-virus software, … and if you work across a network you are basically on your own anyway as Adobe specifically discourages this.
What are your OS, program version, …?

Could not save....because the file is already in use or was left open

I have been using PS since V5 and have never experienced this problem which continues to crop up in PSCS3. I get this stupid error message "Could not save....because the file is already in use or was left open." Even if I save as a new file which does not exist anywhere in the galaxy, I will get the same &^%$!! message. I have gone to the folders and made sure read only was unchecked in properties. I have lots of disk space and four gigs of high-end RAM. This is particularly frustrating when you are using this software to make a living and a fifteen minute project becomes a 45 minute project. I like everything about CS3 but want to pull my hair out by the roots when I pay for the best photo editing software available and it continues to screw me out of money. Adobe, are you out there? Can anyone help???

Same error intermittently on different files. Windows7 64bit CS4. Saving a file in Photoshop - working from local hard drive - and got the file in use can not save error. We tried changing the name, saving as a different file type with no success. I closed absolutely every application that was running and then stopped all non windows processes from Task Manager and still file in use.
I was finally able to save by choosing "NONE" for the preview instead of Tiff 8-bit in the save options.
The bug is in Photoshop and it is putting a file lock on the preview file that it creates and then not alowing any save with the preview option checked.
After saving without a preview we could close PS and reopen then open the saved file and resave with the preview selected. Closing PS unlocked the preview file.

My biggest 'pain' at the moment is that every time I go to change then save a Photoshop CS3 file it says 'cannot save as the file as it has been left open or is in use by another application'

Rule Number One - NEVER go directly uinto the iPhoto library - there are no user servicable parts in it and making any change no matter how small can corrupt your library and cause data or photo loss
Exactly how were you trying to save a copy of your iPhoto library?
Albumdata.xml does not contain your photos - and again NEVER make any changes to the content of the iPhoto library - no dragging - no changes - never go into the library
We need to know exactly what you did
And probalby the easiest solution is to load your backup from before you messed things up
For reference after you get things working
Moving the iPhoto library is safe and simple - quit iPhoto and drag the iPhoto library intact as a single entity to the external drive - depress the option key and launch iPhoto using the "select library" option to point to the new location on the external drive - fully test it and then trash the old library on the internal drive (test one more time prior to emptying the trash)
And be sure that the External drive is formatted Mac OS extended (journaled) (iPhoto does not work with drives with other formats) and that it is always available prior to launching iPhoto
And backup soon and often - having your iPhoto library on an external drive is not a backup and if you are using Time Machine you need to check and be sure that TM is backing up your external drive

Every time I open a new Safari page, it loads the one(s) that are already open, instead of taking me to a new start page.

Every time I open a new Safari page on my MacBook Pro, it load the one(s) that are already open, instead of a new page. it's 8.0.2. I already went to Preferences and it says new page will open to Favorites....but it doesn't.

Hello beany1818,
Also check in Safari Preferences and look in the Safari Opens with and make sure that it is set to “with a new window” and not “all the windows from your last session”. Take a look at the article for more information.

We used select one choice and it is bind to the iterator. Data of different session are not getting reflected.
Problem Scenario : Two browsers are open with same screen . In browser-1, I am adding new item which display on drop down of same screen. But drop down of browser-2 is not displaying the new added value.
Please let me know how to refresh the data of browser-2 if I added data on different session.

Are you sure backingBeanScope is the correct scope for your scenario?
Session scope sound more appropriate to me.
binding="#{backingBeanScope.Product.si2}"
