Connection must be open for this operation

This error message appear while im running the system. But the connection from the Oracle Client to Oracle 10g database is successfully connected. Do help me to overcome this problem....

Actually we have two (!!!) women DBA... one blonde and one brunette (both very cute, the blonde one is currently single, I could hook you up :))
Thank you for your suggestions Christian...
Going down the list:
Same OS version? Memory configuration? - Same
OS user rights and policies? - Same, since I am loging into all machines as myself. And machine B works regardless of the user that is logged on.
How many oracle homes do you have? - One on each machine -OraClient10g_home1
Does the odbc connection uses an oracle odbc driver or the microsoft "oracle" odbc driver? - "Oracle in OraClient10g_home1"
ODP and ODBC driver from same oracle home? - I am guessing yes since they both point to OraClient10g_home1. Is there any way to check for sure?
Same SQLNET.ORA, same TNSNAMES.ORA? - Yep.
Exact version of ODP library and .Net Framework? - They do have same version of OraOps10.dll (10.1.0.200) and are identical in .Net versioning
Pathes and environment variables - Identical
Is the SQL running in SQL*Plus from machine A? - Happily so
Try SQL Developer. Its using jdbc to run the query. - Runs like a champ
Isolate the SQL in a small program and try again - That was the first thing that I did. Crashes. Seems like .Net just can not run through ODP on this machine (machine A nor machines D, E, and F) at all.
Since I realy have nothing to loose at this point I am going to try to reinstall the ODP on machine A. Any hints of what to watch out for during installation? I am following a standard procedure with all the defaults.
Sincerely.
Thank you
Igor

Excel Export Error: Store must be open for this operation

Hi,
I’m currently running into an issue exporting Reporting Services reports to Excel that I haven’t encountered before. Unfortunately, I’m not able to find much information
about this error directly related to SQL Server Reporting Services. The error occurs on multiple reports with a varying number of rows (static columns). The reports are simple list reports with no custom code, etc.
Currently running SQL Server 2012 and SharePoint 2013. Here’s the related error in the SharePoint ULS log:

Hi K. Beckett,
Based on the error message, the issue may be a timeout issue related to the structured storage which is used as a container for storing binary Office documents. As I know, the structured storage is only used to store OLE objects or macros in Office Open
XML documents. By default, SSRS 2012 use Office Open XML format when exporting a report to Excel. To check whether your report server uses Excel renderer (xls) or ExcelOPENXML renderer (xlsx), please export another report and check the file extension. If it’s
an .xls file, it means that you have enabled Excel 2003 renderer for SSRS 2012. Besides, the name should be Excel 2003 in the drop down list of the Export option if you have enabled the Excel renderer in the rsereportserver.config file, and the EXCELOPENXML
renderer displays as Excel in the drop-down list of the Export option.
So, if you are using the Excel renderer instead of EXCELOPENXML renderer, use the EXCELOPENXML to see if the issue persists.
If it is not the case, I suggest that modify the timeout value for the SharePoint Web Application and the report execution timeout.

Query Window "Connection must be open" error?

Hi:
If I right-click on an Oracle connection and select "Query Window" from the menu I get a query window, but no matter what I try to do, hitting the Execute button results in :
ERROR
Connection must be open for this operation.
Why does it think this connection is not open?
Thanks.

If you have MetaLink, you might take a look at Note:404340.1 (ODP.NET: Connection must be open for this operation)
Perhaps that will be of some help.

That isn't what I said at all. Reread my first reply. The first part is a copy of what you had stated.

That is because when global_names is TRUE, the database link name MUST be same as the global db name of the database to which the link connects to.
You need to drop the database link and recreate it using the global name of the database it connects to.
'link name MUST be same as the global db name of the database to which the link connects to.' - I didn't say 11g.
And I didn't say 'put 11g database global_name=true' because you had already done that! 'after that I set the global_names in 11g as TRUE.
1. 11g - global_names MUST be TRUE
2. 11g - database link name MUST be the same as the global db name of the database to which the link connects to - 10g global db name
3. 10g - gloibal_names setting is irrelevant

Why i see this massegae? (iTunes could not connect to the iTunes store. You do not have enough access privileges for this operation. Make sure your connection is active and try again.)

Hey there Hannuj,
It sounds like you are unable to access the iTunes Store in the iTunes application. Based on the error message I would try the steps in the article here named:
iTunes for Windows: iTunes Store connection troubleshooting
http://support.apple.com/kb/HT1527
Remove pop-up blockers
Some pop-up or ad-blocking programs may interfere with the ability of iTunes to connect to the iTunes Store. Removing them in many cases will resolve the issue.
Flush DNS Setting in Windows
In some cases, the DNS information you computer uses to connect to the Internet needs to be reset. Follow these instructions to flush your Windows DNS information:
Windows XP
On the Start menu, click Run.
In the Open field type cmd and click OK.
In the resulting window, type ipconfig /flushdns and press Return on the keyboard.
You should see a message that the DNS Resolver Cache has been successfully flushed.
Windows Vista and Windows 7
On the Start menu, point to All Programs > Accessories and then right-click Command Prompt and chooseRun as Administrator from the shortcut menu. If Windows needs your permission to continue, clickContinue.
In the resulting window, type ipconfig /flushdns and press Return on the keyboard.
You should see a message that the DNS Resolver Cache has been successfully flushed.
Note: If, in the command prompt, you see this message: "The requested operation requires elevation", close the command prompt and repeat steps 1 and 2 above to be sure that Administrator privileges are used to access to Command Prompt.

How do i resolve my itunes from saying " The itunes application could not be opened. You do not have enough access privileges for this operation."

Everytime i click to go to my itunes, the message "The Itunes application could not be opened. You do not have enough access privileges for this operation." pops up. I have tried my best to fix it by adding another account to my computer and setting that one as the administator and mine as the regular user. When i did that the itunes worked on both, but when i changed my account back to administator and the other account to the regular user my account didnt work but the other one did. I also tried to uninstall and reinstall itunes. This message popped up when i tried to update the itunes to the newest one. And still it wont go away. Can someone help me please. Thanks!

I can't synchronize my iPod's with my iTunes software (Windows Vista Home Premium) due to problems with the access authorization / rights for this operation

Hi there,
I'd like to ask you something:
I'm trying to synchronize all my iPod's (I have as many as 4 iPods: 2 iPod touch a 8 GB each and 2 iPod classic a 160 GB each) with my iTunes software (Version 11.3.1 which is installed on a Windows PC (Windows Vista Home Premium)). Unfortunately, the iTunes software refuses to run the command "synchronize with the iPod connected" regarding each and every iPod I have. iTunes just declares:
Synchronizing is impossible because I wouldn't hold the access authorization / rights for this operation.
I uploaded the songs at issue to my iTunes folder from CD's (all songs are in AAC format now).
What is this access authorization, why was something like that invented and what can I do to get it?
How do I have to proceed in detail?
What would it cost?
I am brand new here and have never ever made a post in any support community anywhere in the world in my life. Well, and I am not excessively knowledgeable about the particular computer or mac language but I know the very basics or can find out about them.
Anyways - can you help me please?
If you can't help me, who can do so?
It would be nice if you could answer me as soon as possible!
Thank you guys

I have a new PC and I am getting the message "The iTunes Library File cannot be saved. You do not have enough access privileges for this operation." I am the only one using this PC and I have Windows 7 Pro and have an administrator account. Help

Can anyone help me with this problem. ITunes message," The iTunes library file cannot be saved. You do not have enough access privileges for this operation." I have administrator account and transferred files from old PC. I downloaded new iTunes program on new PC. I synced my iPhone to new PC, no problem. I deleted old account after indicating shared files to new admin account. Can anyone help?

A belated reply, as the problems itunes has have discouraged me from using it much. If you uncheck the "read only" box, it doesn't stay that way! Next time you use it, the box comes up checked.
I'm still having that problem, even when I open iTunes as administrator.
I've yet to see the answer to this problem. I use itunes mostly to download audiobooks, and I'm ready to download more, and want to save them!

I keep getting dialog box saying " The itunes Library file cannot be saved. You do not have enough access privileges for this operation" I am the only user on this computer and only one library! how do i change access privileges please?

Cannot sync, error message reads" not enough access privileges for this operation

When trying to sync my ipad and iphone with my PC i get this error message "Cannot be sybced. You do not have enough access privileges for this operation". I have a new PC but i have successfully synced these devices before. can anybody please help ?

Just thought I'd put out an update on my problem. It has been solved. I spoke to a tech at Apple at 1-800-275-2279. She had me try a few things that didn't help. Her last suggestion was to uninstall QuickTime and iTunes then reload. She sent me the uninstall instructions at http://www.info.apple.com/kbnum/n93698 which I followed. When speaking to her I told her I was afraid to do this because I saw other people on the discussion board who tried this and lost all of their music. She assured me that that wouldn't happen. I did the uninstall then the install. (Just a note here, I also read on the message board that someone said that to cure this problem you should do the install then open up QuickTime before opening iTunes. I did this also but don't really know if it made a difference.
Bottom line is I uninstalled QuickTime and itunes per the instructions at the site shown above. I then installed both again from www.apple.com/itunes/download. After the download I ran the install and unchecked the box to let itunes start after the install. I then opened Quicktime then closed it. I then opened iTunes and all of my music was there and I didn't get the anoying "iTunes is not set as the default player" and the error after trying to set it. The problem described in my first posting of copying CD's is also gone. So beleive it or not, EVERYTHING is working just like it should. Some of the above steps might not be required but I would follow them step by step because I know they worked for me.

Paging file is too small for this operation to complete.

iTunes wont open. When I click on it, all it says is 'Paging file is too small for this operation to complete. Please help =)
