Troubleshooting NEOSYS Generally

Document Remains Locked longer than 10 minutes after an Internet Explorer Window crashes

Lost/hidden internet explorer window on windows that cannot be accessed keeps document locked until process killed/windows restarted

Symptoms

1. Internet Explorer Windows "disappears" while working on a document.
2. Attempts to reopen the same document (even after the normal NEOSYS ten minute lock timeout) results in a message something like "Cannot be edited because the document is in use by (username)"
3. NEOSYS Support Menu, List of Open Documents shows that the record lock is being actively refreshed every five minutes as per normal NEOSYS process
4. The iexplorer task can be seen in task managers, list of processes even after closing all Internet Explorer window.

Cause

Almost certainly due to windows unreliability when PC is customised with additional software from internet etc.

Work around

Kill the iexplorer task in Task Manager's list of processes or reboot the workstation and wait for up to 10 minutes for the lock to be cleared.

Permanent Solution

1. Remove Internet Explorer Add-ons
2. Reinstall Internet Explorer
3. Reinstall Windows

Add the internet guest account to the security list of the data folder with the default permission of list/read/write

Make sure the read&execute permission is removed

Resolving the 'HTTP Error 500.0 - Internal Server Error' while logging in on IE on a Windows Vista system

Problem

After configuring IIS on Windows Vista you will get this error message while trying to login into NEOSYS from Internet Explorer:

HTTP Error 500.0 - Internal Server Error
Description: This application is running in an application pool that uses the Integrated .NET  
mode. This is the preferred mode for running ASP.NET applications on the current and future 
version of IIS.

In this mode, the application using client impersonation configured with <identity 
impersonate="true" /> may not behave correctly. Client impersonation is not available in early 
ASP.NET request processing stages and may lead modules in those stages to execute with process 
identity instead.

Solution

You can move the application to an application pool that uses the Classic .NET mode by using the following from a command line window (the window must be running as Administrator)

%systemroot%\system32\inetsrv\APPCMD.EXE set app "Default Web Site/neosys" /applicationPool:"Classic .NET AppPool"

Alternatively, you can use any other application pool on your system that is running in the Classic .NET mode. You can also use the IIS Administration tool to move this application to another application pool.

Resolving the 'Class Not Registered' error message while logging in

Problem

While logging into NEOSYS, you will get a popup window giving an error message saying 'Class Not Registered - Server Error'. Typically, you will encounter this error with XP Pro IIS 5.1. As usual, there's way to solve it, however the root cause of this is still unknown.

Anyway, you will get the proper message in the event log:

Event Type: Warning
Event Source: W3SVC
Event Category: None
Event ID: 36
Description: The server failed to load application '/LM/W3SVC/1/ROOT/NEOSYS.
The error was 'Class not registered'. 

Solution

So, what do you do ? This problem is related to Component Services, and when you open Component Services MMC, you will most probably get Error Code 8004E00F COM + was unable to talk to Microsoft Distributed Transaction Coordinator. So, fix the COM+ services first by using the following KB from Microsoft (PRB: Cannot Expand "My Computer" in Component Services MMC Snap-In http://support.microsoft.com/?id=301919):

To resolve this problem, reinstall Component Services as follows: WARNING:

1. Open registry editor, locate HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\COM3, and then delete this key.
2. From the Start menu, point to Settings, click Control Panel, and then click Add/Remove Programs.
3. Click Add/Remove Windows Components.
4. Proceed through the wizard, and accept all of the defaults (including IIS)
5. Restart the computer.

If the above didn't solve it, and you still receive the 'Class not registered' error message, then you need to recreate the IIS packages in COM+, try

1. Delete IIS related package in Component Services MMC
2. IIS In-Process Applications
3. IIS Out-of-Process Pooled Applications
4. IIS Utilities

Next, if you still get the message, try following before re-install IIS if you can't find Distributed Transaction Coordinator in your Services console.

Launch command prompt and run the following command.

1. msdtc -install
2. net start msdtc

Then try re-install IIS.

This should solve the problem

Enabling File Security option on Win XP Professional

Problem

In the Properties of any folders, the Security option does not show, hence you cannot modify the Read, Write options.

Solution

The solution would be to untick the 'Simple File Sharing' option from Tools > Folder Options > View:

B10 & B12 Errors

These errors are in the software and should be immediately escalated to the programmer.

Internet Explorer Menu, View, Text Size doesnt change font size as expected

Cause: This is because the font size is now user definable in NEOSYS and View, Text Size does not override predefined font sizes.

Solution: If you are using Internet Explorer 7 you can scale the screen (including the font size using ctrl + and ctrl - keyboard shortcuts or the font size button on the bottom right hand side of the window.

You can adjust the font size on the User Details form when you login although this permanently applies to all forms not just the one that you are on.

Error on process window "Not enough string space - Out of Memory"

Message

‘RTP27’ Line 1. [B29] Not enough string space – Out of Memory.

Not enough memory to execute Debugger; current program aborted. Press any key to continue

Cause

Unknown perhaps related to some large document or report

Solution

Ask users for any hanging transactions. None other than closing and starting another process

Uploaded jpg files fail to display in internet explorer

Some large jpg files > 2Mb cannot be viewed in internet explorer despite being viewable in image preview, ms paint and other viewers/editors. It is not an issue caused by uploading or downloading the files.

These file appear to have been created on Photoshop CS Macintosh and may be a special type of uncompressed jpg used for production quality files.

Partial solution

Before uploading the files, open them in some editor like MS Paint (right click, edit) and save them. However this results in a loss of quality. Perhaps there is some program that can convert these files to a format understandable by Internet explorer without any loss of quality.

"You have attempted to write to a read-only file"

Message

Error while writing data. You have attempted to write to a read-only file. - or - access to the file has been denied by the operating system. (operating system file name: "..\DATA\ADLINEC\ADAGENCY\REV76467.OV00012618")

Cause

It is almost certainly due to some third party backup or other maintenance software opening the NEOSYS database files when it shouldn't e.g. badly configured third party backup scheduled to backup NEOSYS while NEOSYS is still running. Note that the exact filename varies each time.

Short Term Solution

This can be a serious error that causes damaged files in NEOSYS especially if the filename ends in .OV. Use the usual methods of checking for damaged files e.g. do a backup which also looks for damaged files BUT DO NOT OVERWRITE THE LATEST BACKUP SINCE IT MAY BE REQUIRED for restoration. Then fix the damaged files using the usual methods e.g. by rebuilding/using FIXFILE or restoring databases.

Long Term Solution

Remove the third party backup or other maintenance software or reschedule it to run at a time that NEOSYS is shutdown. Removal of software may require hunting through the windows process list for unexpected programs running.

Resolving "Cannot backup/restore because PROCESS1 PROCESS2 (etc) is/are online" message

This can happen for a variety of reasons if all the NEOSYS processes fail to close down at backup time

1. NEOSYS maintenance windows are left open.
2. NEOSYS processes hang due to software error.

How to kill hung NEOSYS processes

NOTE WELL: If you kill actively working NEOSYS processes (those which are "listening" and not hung/crashed) there is a reasonable chance that the database will be damaged and might need a restore losing possibly large amounts of work.

If NEOSYS processes are visible on the server desktop

Look for processes which don't have "Listening ..." on the last but one line. The times on the left hand side are frozen as at the time of the hang.

You can then click the X to kill the process and confirm that this is OK.

Example of a NEOSYS process that has hung due to a software error resulting in a failure to handle a complex query with a lot of brand codes.

If NEOSYS processes are not visible on the server desktop

You can check if there are any hung processes from the NEOSYS Support Menu, List of Database Processes.

1. Shutdown NEOSYS by TEMPORARILY putting a file called GLOBAL.END in the parent directory of neosys. Leaving the file there would prevent NEOSYS from starting up again. Shutting down NEOSYS from the Support menu will not work because of the hung processes.
2. Use Windows Task Manager to kill all the NTVDM tasks. Don't kill active NEOSYS processes.

Temporary workarounds for hung NEOSYS processes

Until the error in the software is fixed users can often get their results by simplifying their requirements. For example select individual clients instead of selecting all the brands for a particular client. If the user has repeated his request (in forlorn hope that it would work finally) then the number of NEOSYS working NEOSYS processes will drop causing severe slowdown for other users and complete stop if all the NEOSYS processes hang.

How to fix a NEOSYS process which opens up in a notepad instead of Microsoft Windows Based Script Host (i.e. DOS window)

The NEOSYS process (cmd file) might open up in a notepad, instead of the usual black colour DOS window. This can be fixed by the following:

1. Download and install the Windows Script 5.6/5.7 from the Microsoft Website
2. Go to any folder, click on Tools > Folder Options > File Types and find the .JS and .JSE and change the default program to wscript.exe (from windows>system32)
