Planning for the Net.Data Error Log

When logging errors, you need to plan for the following issues:

• Determining disk space:

  If you plan to use error logging, you must allow additional disk space for the error logs.

• Configuring Net.Data:

  If you plan to control the error logging for the whole Net.Data system, set one configuration variable in your Net.Data initialization file: DTW_LOG_DIR

  This variable is required for error logging, even if you have set the DTW_LOG_LEVEL variable in your macro to error or warning. See DTW_LOG_DIR: Error Log Location Variable to learn how to update the initialization file.

• Writing Net.Data macros:

  Set the level of logging with the DTW_LOG_LEVEL keyword in your macro.

• Running Net.Data:

  If you are using error logging, then you can check the error logs and archive files for errors in your Net.Data system.

• Tuning:

  Be aware that logging can affect performance. See Setting the Error Log Level for information about performance issues.
