Error Message
121 ISAM error: cannot write log record.
Error Details
The ISAM processor is trying to open the transaction log file but has received an error from the operating system. Look for operating-system error messages that might give more information. For C-ISAM programs, review the parameter passed to islogopen. Make sure that it specifies the correct filename of an existing, writable log file and that it includes a path if the file is not in the current directory. For SQL products, the START DATABASE statement establishes the transaction log file. Make sure that the log file still exists in the same directory location as when START DATABASE was issued and that your account has write access to it.
