Checking the integrity and identity of cache files against the IMPAX
AS300 database
You can use the cache check and repair tools to check the integrity and identity of cache files against
the IMPAX AS300 database.
To check the integrity and identity of cache files against the IMPAX database
1. In a command prompt, change to the location of the cache check and repair tools.
2. Run mvf-check-cache parameters path_to_cache
where parameters can be one or more of the following:
• -i seconds —Interval between display of progress messages. Default is every 10 seconds.
• -g—Gentle cache check. Causes the tool to sleep every other second (and take twice as
long).
• -m mv_command_file —Path to the script of the mv commands that move problem files out
of the cache directory and to a set of sibling directories on the same file system. Do not run
this script on a damaged file system.
• -q—A quick check of file existence only, and a simple file size sanity check. Cannot be used
with the -m parameter.
A report and additional diagnostic messages are written to the log file.
For example:
mvf-check-cache -q /cache3/mvfcache
Finding files in a cache directory that are unknown to the database
Files in the cache directory that contain invalid file name formats or are not registered in the database
must be identified and possibly moved to another location.
To find files in a cache directory that are unknown to the database
1. Run mvf-clean-cache parameters path_to_cache
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 the tool to sleep every other second (and take twice as
long).
• -m mv_command_file —Path to the script of the mv commands that move problem files out
of the cache directory and to a set of sibling directories on the same file system. Do not run
this script on a damaged file system.
• -v—Increased verbosity. Causes all progress and report messages to be prepended by the
current date and time.
