OracleConnection.ClearAllPools() throws exception Operation not valid due t

My app allows new logons so during the app startup I call my general "new logon" procedure that among other things does a ClearAllPools.
OracleConnection.ClearAllPools() throws exception "Operation not valid due to current state of the object".
I have converted from
System.Data.OracleClient.OracleConnection
to
Oracle.DataAccess.Client.OracleConnection
Did not have any problem when using the former.

According to the documentation, ClearAllPools() throws an exception if there's no connection pool to clear. Most likely in that case the System.Data.OracleClient version is just not doing anything instead.
You should just be able to catch InvalidOperationException() at that point and ignore it.

when i was trying to deploy a SP solution from my vs 2012 solution. this error is displayed.
i tried many things like
1) get the wsp and apply power shell cmds to add and deploy, here also it failed:
Add-SPSolution -LiteralPath d:\mywsp.wsp
Install-SPSolution mywsp.wsp -GacDeployment -AllWebApplications -Local
2) restart the timer services and do iisreset and reboot the server. etc .as mentioned in one of the the below blogs:

but even after doing all these steps, the error still persists!. and am not deploying into a remote server, the dev env is in a VM, where sp 2013, vs 2012, sql 2012 are installed.
just wanna share one note: there is a isue in my search admin component. index was reset due to some reason. and from that time onwards my search full/incremental crawls were not working!
will this cause an issue in my wsp deployment ? i hope it wont, still asking...
can anyone help me how to resolve this error.because this is a show stopper for me for the last few days!
help is highly appreciated!

This issue cause because of feature activation failure while WSP deployment.
when you create a WSP using visual studio, it creates WSP package with default deployment configuration settings.
Please restrict feature activation configuration, this will help you to troubleshoot this issue.
- Click on Project in WSP and press F4, it will open "Project Properties"
- set "Active deployment Configuration" - as "No Activation"
- you can activate this features in required sequence after deployment using Activate-SPFeature

Error_27_Error occurred in deployment step 'Activate Features': Operation is not valid due to the current state of the object.

I created a SharePoint 2013 farm solution project in Visual Studio 2013 (running on the same machine where SharePoint 2013 server is running) with
event receiver. I added web.config at project root level to store connection string (I'm working off external SQL DB) and got the following error during deployement:
Error 27
Error occurred in deployment step 'Activate Features': Operation is not valid due to the current state of the object.
When I commented out the ConfigurationManager.ConnectionStrings["MyConnectionString"].ConnectionString; the error went away. Am I missing something or not supposed to add my own App.config to SharePoint project solution?

Hi,
From your description, you might want to store your connection string in web.config and there is an error during deployment.
It is recommended to store the configuration data of SharePoint solution in either property bags or hierarchical object store.
The links below will provide more information about this:

Destroying connection that is not valid, due to the following exception [com.microsoft.sqlserver.jdbc.SQLServerException: Connection reset]

Hi everyone,
I'm facing the following problem in a Server runing Linux with JBoss AS 4.2.2, JRE 1.6, and MSSQL Server 2005 with JDBC 2.0 (sqljdbc4.jar).
The thing is: on friday morning I started up the server and everything worked fine ... next, from Friday at 6pm to Saturday at 8am nobody has used the system.
Then on Saturday at 8:05 got the following warning lines every time I tried to do something in my application. While it seems that everything works, after a few days the system starts to decrease their performance and malfunction, so I want to know why it
might happen these warnings.
I have tried to find a solution to this problem in several places but I'm not succeeding. That's why I'm writing my problem here...
Hope somebody can help me!
Thanks in advance and best regards!
Cristian.

I´m facing similar problem with Linux and SQL Server 2008 R2. I made the downgrade of JDK 1.6 from 27 to 26 (some people reporting errors when upgraded to jdk1.6_29 and rolling back is ok) but for me the error persists. At this moment we are testing with

Microsoft RMS Add-in Operation is not valid due to the current state of the object

Microsoft Rights Management sharing application for Windows

Click 'Share Protected'
Receive the following error message 'Microsoft RMS Add-in Operation is not valid due to the current state of the object'
Microsoft Windows 7/Office 2013 Service Pack 1
Works fine
Any ideas why this is not working?

Hi lra,
As per my understanding, I think this issue can be caused by MaxHttpCollectionKeys settings in report manager web.config file.
For more details, please refer this similar thread to override the default value of MaxHttpCollectionKeys:

[SOLVED]wlan0 up - Operation not possible due to RF-kill

Hello everyone.
I've encountered trouble trying to activate my wlan0 interface and I was wishing that someone here might be able to help me.
$ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default
link/loopback
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
link/ether
3: wlan0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
link/ether
My attempt at trying to activate wlan0 renders the following;
$sudo ip link set wlan0 up
RTNETLINK answers: Operation not possible due to RF-kill
Unblocking everything with RF-Kill does not seem to change much in particular:
$rfkill list all

$sudo rfkill unblock all
$rfkill list all

Soft blocked: yes
Hard blocked: no

Enabling/Disabling the wifi-button on my keyboard only changes the Hard Blocked-parameter of hp-wifi. The Soft block remains unchanged regardless of me trying to unblock all with rfkill.

It is worth mentioning that this problem has remained persistent throughout multiple linux distributions that I've tried on my laptop. The Wifi works fine in Windows 7 but as soon as I switch to any linux distro it stops working.
I intend to put your advice to good use so any help would be very appreciated.

As I can see you have two wireless interaces, when i see only phy0 with rfkill, it's maybe your hp-wifi that force to disable phy0 interace. I think if you blacklist the driver it might allow phy0 to be enabled.
Please download and install lshw available in the community repo and enter in a terminal :
$ lshw -c network

B1 8.8 EventLogger: Cross-thread operation not valid

Greetings,
I'm trying to run EventLogger on Windows Server 2008 for use with B1 8.8. I converted EL to VS 2005, updated it to use the new UI for 8.8 and when EL runs it crashes as soon as it receives an event.
The message is "Cross-thread operation not valid: Control 'ToolBar1' accessed from a thread other than the thread it was created on.
Does anyone have any ideas? I wouldn't be surprised if it's a security issue, but I wouldn't know how to fix it even if it were.
Thanks!

Sheer Genius, Eddy - thanks!
I tried recompiling the program and used the advanced compile option to tell it X86 but that didn't solve it (by itself, anyway) but when I used the compability mode everything was smooth.

Exception "Operation not premitted"

I installed Firefox 32.0.3 and im working on a silverlight project. Firefox shows exception "Operation not premitted" but IE & Chrome working on this project prefectly. Help Please

i think limitation with Firefox. Because silverlight working fine on IE & Chrome. See Image of Exception that may help to understand what is problem!

Constructor can throw exception or Not ?

Anybody please tell me if the constructor throws an exception or not ?
Please reply soon
Thanks
Amitindia

A constructor can throw an Exception. However I
would suggest throwing the generic Throwable, Error,
Exception or RuntimeException rather than a specific
exception is bad practice and you should choose an
appropirate exception to throw.All depends on wich kind of exception you are throwing,checked or unchecked. It's an even worse form to throw a RE, Error, or Throwable when you are throwing in fact a checked exception.
Nevertheless, I do agree, you must always strive to not throw exceptions, of any kind, in your construtor code. Construtors should be simple and reliable. Unles you have a very compelling reason to not do it, try to isolate the risky parts of the code where they are called ofter object construction or class loading.
May the code be with you.

Error occurred in deployment step 'Activate Features': Operation is not valid due to the current state of the object.

I recently copied a solution from one dev box to another. After pushing through a handful of other errors I hit a wall with this one. Any hints as to the human translation would be appreciated. The solution works on the original box. Also if there's
a way to make the Forum Category list on this page smaller but with more items while making the icons and white space bigger, Microsoft would like to know. Thanks

Hi George Takei,
This is a common error message which is not easy to find the root cause directly.
Here are some general checking steps:
Check to make sure you haven’t change any objects like namespace, class name, that make feature cannot find specified class.
Deactivate the feature on the site, reset IIS, and redeploy the solution.
Kill the vssphost4.exe in Task Manager, to redeploy the feature.
If the issue persists, it would be better to share the solution here to help to do troubleshooting, what’s the solution used for, is it an event receiver, feature, workflow or other type?
Thanks,

What I meant is that it's done any kind of alteration of the tables involved, because the user does not change any of your information on the screen.
The problem happens on a client and does not happen in our test environment.
The version of Oracle.DataAccess both 32-bit and 64 bit is 2.112.1.0.
What is the code in the following summary:
1) Is created transactional context:
Dim TxOptions As New TransactionOptions
Dim OpcaoDeEscopo As TransactionScopeOption
Dim Transacao As System.Transactions.TransactionScope
TxOptions.IsolationLevel = Transactions.IsolationLevel.ReadCommitted
OpcaoDeEscopo = TransactionScopeOption.Required
Transacao = New TransactionScope(opcaoDeEscopo, TxOptions, EnterpriseServicesInteropOption.Full)
2) From this point are open connections are made and query commands to the database.
Are opened and closed connections to the database.
3) At the time of effecting the transaction Dispose of the error happens:
Transacao.Dispose
Note: Our way of working has its own peculiarities, the connection pool is always disabled: ";Pooling = false". It is inserted directly in the connection string. We need to do this because the pool had memory problems turned prey.
Therefore the process of opening and closing connections, you can leave the system slow. So to avoid open connections within the transactional context, in some cases we enforce the transaction enlist. As follows:
Dim TransacaoCorrente As ITransaction = CType(ContextUtil.Transaction, ITransaction)
Conexao.EnlistDistributedTransaction(TransacaoCorrente)
Can you help us?

Hi Sandeep
You are using Service Pack 5 (Crystal Report Version : CRforVS_13_0_5.exe). I'd like you to update your install to SP 13:
SAP Crystal Reports, developer version for Microsoft Visual Studio: Updates & Runtime Downloads
and test.

Operation is no valid due to current state of object.

I have created a web part. And in that web part I have a link which refer to a page in share point with query string.
Some thing like as :
<a href=http://sharepoint:79/codelibrary/PageName.aspx?Id=1/>
It gives the error that Operation is not valid due to current state of object.
But when I call this page with out Id=1 or without any query string, it works fine.
Please help me, where I am doing wrong.
Many Thanks
