Troubleshooting

This section explains the errors that you can encounter while installing and configuring Mart, and how you can troubleshoot them.

Note: The Mart Server log files are available in the following location:

Windows 7: {user.home}/AppData/Local/erwin/Mart Server/logs/application.log

The latest version of Apache Tomcat does not support custom authorization-related error messages. Hence, a generic error message, "Unauthorized operation attempted. For more information, please review the log file.", is displayed. To understand the cause of the error, review the application.log file, which contains the description of the cause. Following is one such sample from the application.log file:

ERROR exception.MMException.setException: java.lang.Exception: User "johndoe" does not have required "View Users" permission on "User Management". Please contact the Mart Administrator for required permission.

Unable to use a Reserved Word

Symptom:

When I try to reverse engineer from a script, I get the error message, "RES-1:Syntax Error - Line <number>, Offset11 <word>".

Solution:

This error message appears when you use a database-specific reserved word or a keyword. Add the quotation marks (" and ") around the word in the script and then reverse engineer.

Unable to Locate Client Connectivity Software Ora7nt

Symptom:

I am trying to connect to an Oracle 11g database and I am getting the message, "Unable to locate client connectivity software Ora7nt.dll."

Solution:

erwin® Data Modeler is a 32-bit application and requires 32-bit client libraries to connect to the database. The reason for this error is that the application could not find the required Oracle client to connect to the Oracle instance.

Try one of the following solutions:

Install the Instant client software that is available from Oracle into a directory that does not contain any spaces in the PATH. For example, C:\app\Administrator\Oracle.
If both 32-bit and 64-bit Oracle clients exist on the same computer, then ensure that the PATH environment variable refers to the 32-bit Oracle client. Include the path "C:\Oracle\product\11.2.0\client_32\" at the beginning of the variable value.
