This morning I couldn't start the Metastorm engine on one of my v9.2 installations. I had the following error in the Application event log...

Service cannot be started. Metastorm.Common.Addin.ServiceException: The service threw an exception at start up and has failed to start
 Service: Wcf Hosting Service
 Service type: WcfHostingService ---> System.TypeLoadException: Could not load type 'System.Security.Authentication.ExtendedProtection.ExtendedProtectionPolicy' from assembly 'System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.
etc etc

Bad start to my day ! However this was fixed by installing the KB975954 .net 2.0 framework hotfix from Microsoft.

Hope this helps someone else.

I have installed Metastorm V9.3 on Windows Server 2003 Standard SP2 32bit where i have installed Oracle database 10.2.0.4.
When I try to start Metastorm Process Engine i found the following errors in the Application event log :
 
ODBC database connection string points at different database to Database connector.
 
A problem occurred during initialisation. The Metastorm Process Engine is shutting down.
 
Metastorm Process Engine stopped.

The .NET database connector failed to initialize: System.NullReferenceException: Object reference not set to an instance of an object. at eWork.Engine.ScriptHost.ScriptHostLoader.createObject(String assemblyName, String typeName) at ManagedConfiguration.StopCoreServices(HStatus* ).
 
Is anyone that can help me ?

I suspect that the ODBC connection set up is incorrect, or perhaps the wrong ODBC/OLEDB driver version.

Did you set it up with the install script? Does the install script set up the Oracle database (it used to be run manually). If not, what does the install script set up?

Hi, we have the same problem in a OpenText MBPM 9.3 installation. In the application log we find:

The .NET database connector failed to initialize: System.NullReferenceException: Object reference not set to an instance of an object.

   at eWork.Engine.ScriptHost.ScriptHostLoader.createObject(String assemblyName, String typeName)

   at ManagedConfiguration.StopCoreServices(HStatus* ).

The server is a Windows 2008 R2 64bit. We have create the ODBC entry both 32bit and 64bit. The Oracle Client is 11.2.0.3 version. 
What have we to check? The engine does not start.

Thank you in advance,
Paolo

I don't know if you have access to the OT Knowledgebase (now that things that used to be open is now secured), but they seem to have logged/raised this recently at https://knowledge.opentext.com/knowledge/cs.dll?func=ll&objId=48990409&objAction=ArticleView&viewType=1

Copying highlights from that post:
1. Check the database connection strings to make sure they are set correctly and are pointing to a valid database.
2. If this is an Oracle DB, check what version of Oracle client drivers you are using. If this is a 64bit server you will need to install the 64bit Oracle Client drivers then the 32bit Oracle client drivers.
3. You may need to manually run the database scripts again to create the appropriate tables and stored procedures.
4. If this is an 64bit system, make sure you use the Windows\SysWOW64\odbcad32.exe ODBC Editor, as the 64bit ODBC Editor does not update the ODBC connection correctly.

I our experience, the different drivers must be installed in the correct order. When done so, the Designer fails to connect to the repository, but reinstalling the drivers for the Designer (64-bit) fixes the issue.

It is not good, by any stretch, but it does work in the end.
