I got an error SQL1042C. An unexpected system error occurred. Explanation: A system error occurred. One possible reason for this error is that the database manager is not installed correctly or the environment is not set up correctly. On OS/2, while trying to start the database manager, a very common reason for this error is a corrupted NET.ACC file. The command cannot be processed. The tables and views would not be opened. What is the way to open the dataase? pls help me
