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.
