User guide

A report and additional diagnostic messages are written to the log file.
For example, run:
mvf-clean-cache -m move_cmds.sh /cache4/mvfcache
Moving images from a cache directory
You can move the images identified by the mv_command_file, used to identify problem files.
To move images from a cache directory
1. Run the mv_command_file .
For example, run move_cmnds.bat.
Generating a report of lost images
This procedure is designed to be run on a server that has suffered damage to one or more cache file
systems. This procedure generates a report of studies that contain DICOM object files that have been
lost from a server’s cache and deregisters the missing files from the database.
To generate a report of lost images
1. Run mvf-report-loss parameters report_file_name
where parameters can be one or more of the following:
• -i seconds —Interval between display of progress messages on stderr. Default is every 10
seconds.
• -g—Gentle cache check. Causes tool to sleep every other second (and take twice as long).
• -r—Run in deregister mode, changing the visible field values from 'C' to 'F' and permanently
deleting all database locations for missing files. This action cannot be undone. It has no
effect if the tool has never been run in marking mode.
Note:
If you omit the -r parameter, the tool runs in marking mode and checks all of the caches
on the local server. If a file is missing, the visible field on the osr_location table is set to
'C', effectively making the file location “invisible”. If a tool is rerun and files have since
been restored to cache, the visible field values are set back to "T".This is a default
mode.
For example:
mvf-report-loss loss-report.txt
IMPAX system consistency is restored by deregistering missing cache files from the database.
