PM82200: Crash after specifying conenction in .mst file and running DB Reverse Engineering/schema generation/synchronization

APAR status

• Closed as program error.

Error description

• Description: After specifying a database connection in the
  sa2001.mst file, attempts to perform DB Reverse Engineering, DB
  schema generation or DB synchronization in IBM Rational System
  Architect leads to error 'Run Time error 13 , Type Mismatch
  (Diff Engine)'
  
  Expected Results: No Error, and in the Database Synchronize,
  Generate and Reverse dialog the database connection specified in
  the .mst file is seen
  
  Actual results: Crash or Run-time error
  
  Impact: Client has a business case to auto populate server
  information in DB reverse engineering, so they set it in the
  .mst file. The run-time error appears and they have to kill
  sa2001.exe via task manager.
  
  Inputs: None
  
  Procedure:
  
  1. Launch Rational System Architect
  2, Open any encyclopedia of your choice
  3. Click on Tools ? DB Reverse Engineering
  4. Select SQL Server 2005, hit Next
  5. Set a live database connection.
  6. Finish the reversal. It should be fine.
  7. Exit SA.
  8. Go to your sa2001.ini file
  9. Under  the [DBMS-Synchronization] section, and copy and paste
  the following values to the sa2001.mst file:
  
  [DBMS-Synchronization]
  DBMSName=SQL Server 2005
  txtRDELeftConnectionString=
  txtRDELeftDBMS=
  
  10. Restart SA and open the encyclopedia
  11. Click on Tools ? DB Reverse Engineering or DB schema
  generation or DB synchronization.
  12. Select the target DBMS (SQL Server 2005) and click Next
  13. System Architect just disappears.
  
  In a Citrix environment, SA will show 'Run Time error 13 , Type
  Mismatch (Diff Engine)' error. After I click OK on the error
  message, and close the Database Synchronization dialog via
  hitting the X in the upper right-hand corner, SA is
  unresponsive. I have to kill SA via the task manager on the
  Citrix Server.
