Reports, Statistics and Logs

Progress Reporting

IMSDBU reports the progress it makes while processing a database function. When performing a database load or a logical pointer update, it shows a 'percent complete' and an estimate of the time remaining. For database unloads, a percentage cannot be calculated so IMSDBU displays the segment number in process. The frequency of progress reporting is controlled by the PROGRESS directive.

Detailed Reporting and Statistics

A detailed report showing the results of a database function is available. This report is produced as an ASCII text file. It can reflect the most recent function or can maintain a historical record. This reporting is controlled by the LIST and LISTOPEN directives. Items included in this report are:

• A starting message indicating the date/time, database name and the function performed.
• 'Options in effect' which lists the directives used.
• Information, warning and error messages issued during execution.
• Database statistics with the Load and Unload functions. These include segment counts, maximum per root, and average per root listed by segment type.
• The ending message produced by the function. This states the success or failure of the function and the ending return code value. This message also appears in the historical activity log.

Historical Activity Log

A historical activity log can be kept for all IMSDBU activity. An entry is written to the log when a function completes. This entry consists of the date and time, database name and the ending message for a function. The most recent entries are written to the end of the file. This log is produced as an ASCII text file and is controlled by the LOG directive.
