I have an RDBM which needs to be converted to MySQL. I would like to open the database with Workbench and get a file to someone. However every time I run the migration wizard for a Microsoft Access RDBM, ODBC data source parameter, and then find the data source to migrate, it simply just blocks the process on the test, saying:
"Test Source DBMS Connection:
Operation Cancelled"
The RDBM is either type .mdf, .accd or 5.3 ANSI. None allow a connection. I have searched Oracle and other sources online with very few hints or clues as to why this happens to my database. The only other alternative is buy some expensive conversion software. Please help! I have not a clue what information might be of use to me to solve this problem. I have used the standard Oracle/MySQL tutorial: https://dev.mysql.com/doc/workbench/en/wb-migration-database-access.html
Also to note I have tried disabling all firewalls. And the general ODBC connections I make just quit working, saying in various ways they cannot connect. Any resources to point me to that might be helpful with some more basics on this?
I also found this resource which explains why certain pipe connections are not working for ODBC: http://dev.mysql.com/doc/refman/5.6/en/can-not-connect-to-server.html It lists some command prompts which I am uncertain how to use or where to enter. I tried running these as admin on a standard cmd but they just say command not recognized.
I've just encountered the same issue while testing out the MySQL workbench software.
I had installed the 64-bit version of MySQL Workbench. However, I only had 32-bit Access, and so the ODBC drivers were all 32-bit. Uninstalling and installing 32-bit version of MySQL solved this issue and let me connect to my local Access database for migration. (download 32-bit installer from here: https://dev.mysql.com/downloads/workbench/)
I know you found a work-around, but if you wanted to go back to Workbench, checking that you are using all 32-bit (or all 64-bit) software & drivers might help.
Cheers,
Dave.
On "System DSN" (32 bit) press Add select Microsoft Access Driver (.mdb,.accdb), press Finish, On setup page press 'select' and map to the database you want to connect to and click on the database on left pan click ok. add database name and press OK. close the window. now you can use ODBC for access in MYSQL(32 bit).

I've written a program in VBA (not excel) to upload data to a PostgreSQL database using ADODB via a DSN. Often it works without a problem, but sometimes I get a "Specified driver could not be loaded due to system error 127" error. When I get this error, I've found that the only solution is to restart my machine (which acts as both the client and the server in this case).
I've tried modifying the DSN to use either 32-bit or 64-bit, but that hasn't helped. When the error occurs, I've tried restarting the PostgreSQL service, but that hasn't helped either.
I've googled for solutions, but nothing seems to help.
I'm hoping for some solutions to either resolve the problem or offer an alternative to this method that bypasses the problem - any suggestions would be great.
Happy to share code if it helps, but it's all simple tutorial level stuff.
I have a simple PHP application running on this server which allows other people to verify some information on-line. The apache was running OK until a few days back.
The application uses Postgrees and the apache service was configured by an add-on "Enterprise Db Apache", it was not configured by me and is connected to a portal to be shown on-line. This was kinda dropped on me and I had no prior knowledge or experience with databases nor servers and need to put it back on-line. How can I start to find out what made it stop?
Here's a link to the error I'm receiving when trying to start it back again:

Tried updating .NET to no success,
I've searched around SO and all the threads I found were based on custom services people wrote, and found out that this error code is very generic, I'm very lost and have my neck on the chopping block.
EDIT: Tried some fixes suggested here but had no success. I'm thinking about reinstalling the service, is it a really bad idea? Is there a safe way of doing this without loss of data in the Database? Is there a tutorial on this here already?
The problem was with compatibility of the versions of C/C++ libraries in the server which lead to the programs related to the service not being able to start properly. A simple reinstalation of the compatible version of the libraries made the service able to be started again.
Maybe your service is taking longer time than 30 seconds (Windows default timeout) to start and report ready to the Service Control Manager. Usually this happens because of performance issues.
A possible solution for this is to extend it through the Registry.
Go to Start > Run > and type regedit
Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control
With the control folder selected, right click in the pane on the right and select new DWORD Value
Name the new DWORD: ServicesPipeTimeout
Right-click ServicesPipeTimeout, and then click Modify
Click Decimal, type '180000', and then click OK
Restart the computer
I have a Windows Server 2008 Datacenter Edition VM on linux-xen. It has been working fine until a few days ago apparently it attempted to install an update. I have tried everything I can think of to get passed the 'Preparing to configure Windows' splash screen.
I have tried:
Booting into all three options of safe mode, all three performing the same splash screen step and endless reboot cycles.
Booting into last known good configuration, again boots to splash screen
F8, boot into repair, open cmd and use dism.exe /image:d:\ /remove-package PackageName:, which results in an error that I have found no information google about.
I have tried deleting windows\winsxs\pending.xml, it is currently deleted but still tries to configure updates.
Use dism.exe with the /revertpendingactions switch, which still brings me back to splash.
dism /image:D:\ /cleanup-image /revertpendingactions
Tried to repair via the installation disc, which does not have an OS repair option, just the same 3 options for Memory Diagnostics, Command Prompt and System Recovery
I did not realize that Windows Server 2008 DC Edition did not default to system restore points being enabled. Apparently I have no restore points available to revert to.
I am going out of my mind trying to find some successful way to get passed this splash screen for configuring windows updates. If the pending.xml file is missing then I do not understand how it could still be trying to configure updates.
I am at a loss, any additional troubleshooting steps or advice would be appreciated. In terms of advice, I now realize I need to double check that restore points are enabled and take regular windows system recovery disk image backups so that I have better restoration capabilities in the future.
Being that this is on a linux-xen guest, I could duplicate it and try other means, but I am not sure what else there is to do.
Can I reinstall windows 2008 server back on top of it again and achieve some sort of success without breaking all of the licensing, rdp users, profiles, data ETC? This server is not a member of a AD environment. It is simply a standalone server that allows 10-12 users to RDP to access a few applications.
However, regardless how I move forward the data on the server is needed even if I were to opt for creating a new VM with a fresh install for them to use.
Is it possible to inform Windows to skip the update installation / configuration procedure during boot by adding a particular switch to the Boot options? Currently it has:
/NOEXECUTE=OPTOUT
I am curious if it has some alternate runlevel like linux does that would potentially allow me to bypass this wretched situation.
Mine was stuck until I hit CTRL + ALT + DEL. It seems like it was a service pack that did it. I waited a few hours for it to finish when in fact all I had to do was hit CTRL + ALT + DEL.
I want to keep a log with the attempted log-in to a machine. The OS is Windows Embbeded Standard. Is it possible to make Windows execute an application or a script after every login attempt to enable me to save that information in my database?
EDIT:
Extract from Superuser:
"Here, you can set auditing to all types of events. I believe the one you want is "Audit logon events", Set it to Failure (or Success as well if you want).
All events will now get sent to Event Viewer. ..."
Is it possible to access the Event Viewer info via WMI?
From a security viewpoint, I would assume this would not be possible. But it is possible to write your specialized GINA library which would replace the standard login system of Windows. This was done to support fingerprint readers and smart card readers, and many other alternative login methods.
But out of curiosity, what kind of problem are you trying to solve here? Windows already has plenty of build-in functionality which can be analysed by anyone who can log in.
Follow this link to see how it's done in Windows 2003. I've checked with Windows XP on a virtual machine and it works exactly the same there. So I assume it also works in embedded XP versions.For reading the event log, this link from MSDN will be practical too. This will require .NET though, which is optional on Windows XP.
WMI might be a good place to start. You could use WMI (or another method) to query the security event log for sucessful/failed logon events, too.

I have a web site that I developed on Vista using Vb.net9. It makes a connection to Oracle. for the connection I use System.Data.OracleClient. It works fine on my machine, and our test server, but it does not work on the production server. We installed the Oracle Client 11 on the server. The error is System.Data.OracleClient requires Oracle client software version 8.1.7
We've tried, making a console app that opens the connection, connection runs fine, opens, displays a message and all is well there.
Then we make a simple web form, put it in the directory of the program, just a button, opens the connection, try..catch, grabs error, same error.
The console app was running under an Administrator, web site running under iwam. Is it possible that iwam has a different path?
I've run into this error dozens of times:
Cause
Security permissions were not properly set when the Oracle client was installed on Windows with NTFS. The result of this is that content of the ORACLE_HOME directory is not visible to Authenticated Users on the machine; this causes an error while the System.Data.OracleClient is communicating with the Oracle Connectivity software from ASP.NET using Authenticated User privileges.
Solution
To fix the problem you have to give the Authenticated Users group privilege to the Oracle Home directory.
Log on to Windows as a user with Administrator privileges.
Start Windows Explorer and navigate to the ORACLE_HOME folder.
Choose properties on the ORACLE_HOME folder.
Click the Security tab of the Properties window.
Click on Authenticated Users item in the Name list.
Un-check the Read and Execute box in the Permissions list under the Allow column.
Re-check the Read and Execute box under the Allow column.
Click the Advanced button and in the Permission Entries verify that Authenticated Users are listed with permission: Read & Execute, and Apply To: This folder, subfolders and files. If not, edit that line and make sure that Apply To drop-down box is set to This folder, subfolders and files. This should already be set properly but it is important that you verify it.
Click the OK button until you close out all of the security properties windows. The cursor may present the hour glass for a few seconds as it applies the permissions you just changed to all subfolders and files.
Reboot, to assure that the changes have taken effect.
Try your application again.
The author of this post (now deleted post) suggests checking your C:\Windows\System32 folder to make sure that the oci.dll exists there. Copying in the file from the Oracle home directory solved this problem for me.
Update 1: It is possible for different users to have different path. But its not the likely problem here. There is more chance that the user that the iwam user doesn't have permission to the oracle client directory.
Update 0: Its suppose to work. Check for environment variable ( That are needed to find the oracle client and tnsnames.ora ). Also, Maybe you have a 32/64 bit issues. Also, consider using the Oracle Data Provider for .NET ( search for odp.net)
Oracle Client version 11 cannot connect to 8i databases. You will need a client in version 10 at most.
When we first moved over to Vista with Oracle 10g, we experienced this issue when we installed the Oracle client on our Vista boxes, even when we were running with admin privileges during install.
Oracle brought out a new version of the 10g client (10.2.0.3) that was Vista compatible.
I do believe that this was after 11g was released, so it is possible that there is a 'Vista compatible' version for 11g also.
Why not use this: dotConnect for Oracle (formerly known as OraDirect .NET)?
It can be configured to not require an Oracle Client at all.
We have been using this in both Windows Services and ASP.NET Web Services and it works like a charm.
For me, the issue was some plugin in my Visual Studio started forcing my application into x64 64bit mode, so the Oracle driver wasn't being found as I had Oracle 32bit installed.
So if you are having this issue, try running Visual Studio in safemode (devenv /safemode).
I could find that it was looking in SYSWOW64 for the ic.dll file by using the ProcMon app by SysInternals/Microsoft.
Update: For me it was the Telerik JustTrace product that was causing the issue, it was probably hooking in and affecting the runtime version somehow to do tracing.
Update2: It's not just JustTrace causing an issue, JustMock is causing the same processor mode issue. JustMock is easier to fix though: Click JustMock-> Disable Profiler and then my web app's oracle driver runs in the correct CPU mode. This might be fixed by Telerik in the future.
