PInvoke Invalid Metadata error on Oracle DB

PInvoke Invalid Metadata error on Oracle DB

I am trying to connect to an Oracle DB using Mimer. I'm getting the following error when I execute the MpmConnection.Open.


'PatientTracking.exe': Loaded 'c:\windows\assembly\gac\\\', No symbols loaded.

When I use a SQL server connection string, it connects properly. Any ideas?


RE: PInvoke Invalid Metadata error on Oracle DB


What version of Oracle are you using? Have you installed the correct ADO.NET provider for Oracle? How is your DataSource configured?

With a little more information I will try to figure out what is going wrong.

By the way, it is better to use the forum, mailing list or support request at the Mpm SourceForge site,

RE: PInvoke Invalid Metadata error on Oracle DB

Thanks for replying. I'm connecting to an Oracle 10 database (the Mimer Provider Administrator can successfully connect -- so I <i>assumed</i> my drivers and connection string were good).

I don't know about the ADO.NET provider for Oracle -- I did install the Oracle OraClient10g package. What should I look for on my XP system?


      <dataSource dataSourceName="Oracle_Test" pluginName="MsOracle" connectionString="Data Source=SUN9;User Id=validuser;Password=validpassword;" dbmsTypeName="Oracle" />

Thanks for the pointer to the SF forum. To be honest, I thought I followed a link to the forum from the site.

Any additional help is greatly appreciated!
