Diagnosing the problem

You need to examine the Attributes of the Entity referred to by the Data Dictionary Identification (DDID) of the Entity shown in the SA2001.LOG file as follows:

    1. Exit SA.

    2. Start SA with the " -log" option.

    3. Attempt the upgrade of the Encyclopedia.

    4. Open the SA2001.LOG in a text editor of your choice.

    5. Find the time the error occurred.

    6. Notice the Entity name and the DDID.

    7. In SA check the Attributes of the Entity the DDID refers to.

Note: You will find instructions on running with the "-log" option and where the SA2001.LOG file is located in the document 1426029: Available logs with IBM Rational System Architect.

Resolving the problem

To prevent the error and enable the upgrade to proceed you need to remove all invalid and special characters from the Attribute names of the Entity as follows:

    1. Exit SA.

    2. Disable XT optimization in your SA2001.INI file as per the Help page Overriding the Mandatory Conversion for Optimized XT Reader.

    3. Start SA.

    4. Open the encyclopedia.

    5. Export the definition of the Entity to a Coma Separated Value (CSV) file using the menu: "Dictionary > Export Definitions". You then select the appropriate options and press OK.

      Note: This may take a while to complete.

    6. Open the CSV file in a text editor of your choice. You then:

      1. Search for any invalid characters and replace them.

      2. Search for any special characters and replace them.

      3. Save the CSV file.

    7. Import the CSV file of the Entity (and attributes) using the menu "Dictionary > Import Definitions", You then:
      1. Select the CSV file.

      2. Select Definition Type: Attributes.
