Deleting cache locations for studies
(Topic number: 7707)
12.
If you are replacing the 5.2 or 5.3 servers and are not restoring the files in the cache directory after
the upgrade, to prevent database inconsistencies, remove all database references to images in cache.
You must also do this for studies in Client caches, because IMPAX 6.5.3 no longer supports cached
Clients—only cacheless and standalone Clients.
To remove references to images in cache, find all study_refs that are in the cache and delete them.
Note:
Images in the cache are archived and, if necessary, can be retrieved after the upgrade is
complete.
To delete cache locations for studies
1.
On a station with a cache containing database references to remove, log in as the mvf user.

save_refs a select distinct ds.study_ref from dosr_study ds, dosr_object do where ds.study_ref
= do.study_ref and do.object_ref in (select object_ref from osr_location where volume_ref
= volume_ref)
where volume_ref is the volume reference of the cache.

Go menu
5.
