Tips for using the offline archive utility

If the input archive is the primary archive, you cannot unregister it. To work around this, force an archive shift using the piartool -fs command or temporarily shut down PI Archive Subsystem.

If the output file does not exist, the utility creates it.

If a full path name is not specified for the output archive, the utility places the output archive in the current directory.

At the end of processing, neither the input nor the output archives are registered.

The input archive’s integrity is checked prior to being used. To disable this behavior, use the –noinputcheck option.

By default, the offline archive utility creates dynamic archives. To specify a fixed archive, use the -f option.

Note: Dynamic archives become non-shiftable once a single overflow record is generated, but remain shiftable if no overflow records are generated.

You can run the offline archive utility while Data Archive including PI Archive Subsystem is running. At a minimum, the PI Network Manager, PI Base Subsystem, and PI Snapshot Subsystem must be running, because the utility needs to access the PI point database during offline operations.
