Using PACLOG to simulate log processing
You can simulate the processing of archive log data sets by PACLOG without performing any action against the original archive log data set. This capability lets you become familiar with the processing without altering your data.
When you use the SIMULATE keyword in addition to the syntax options used for normal PACLOG processing, PACLOG performs log data set processing without replacing the original log data set or cataloging the processed log data set. When you use SIMULATE, you can
Update the archive history file by using the keyword UPDATEHIST
If you use UPDATEHIST, PACLOG updates the archive history file when processing is successfully completed. If you subsequently reprocess the same original log data set in normal mode, you must then use the REDO option to inform PACLOG to update the entry in the archive history file.
Keep or delete the processed log data set that was created in SIMULATE mode by using the keywords KEEP or NOKEEP
If you use KEEP, the processed log data set is retained. If you use NOKEEP, the processed log data set is deleted. In both cases, no action is performed against the original log data set.
