Configuring trace files on Windows Systems
The DataDirect enhanced tracing library allows you to control the size and number of log files. The file size limit of the log file (in KB) is specified by the Windows Registry key ODBCTraceMaxFileSize. Once the size limit is reached, a new log file is created and logging continues in the new file until it reaches its file size limit, after which another log file is created, and so on.
The maximum number of files that can be created is specified by the Registry key ODBCTraceMaxNumFiles. Once the maximum number of log files is created, tracing reopens the first file in the sequence, deletes the content, and continues logging in that file until the file size limit is reached, after which it repeats the process with the next file in the sequence. Subsequent files are named by appending sequential numbers, starting at 1 and incrementing by 1, to the end of the original file name, for example, SQL1.LOG, SQL2.LOG, and so on.
The default values of ODBCTraceMaxFileSize and ODBCTraceMaxNumFiles are 102400 KB and 10, respectively. To change these values, add or modify the keys in the following Windows Registry section:
Warning: Do not edit the Registry unless you are an experienced user. Consult your system administrator if you have not edited the Registry before.
Edit each key using your values and close the Registry.
