Study Size Query Attributes Calculation

Overview

Eager calculation of study size and study series query attributes can now be triggered using a scheduler.

Archive Version	Notes	Configurations
upto 5.22.5	Calculation of Study Size & Study Series Query Attributes independent form each other	(UPS On Store Rule) + UPS Processing Rule
		(Export Rule) + Exporter Descriptor
5.22.6 onwards	Post calculation of Study Size, Study Series Query Attributes calculation is triggered	Configurable using archive device properties

Configuration

• Using Archive UI :

  • Go to Configuration (page) -> Devices (tab) -> dcm4chee-arc -> Extensions -> Device Extension (Edit) -> Extensions -> Archive Device Extension (Edit) -> Attributes
  • Set Calculate Study Size Delay, Calculate Study Size Polling Interval, Calculate Study Size Fetch Size and Calculate Query Attributes and Save.

• Using LDAP : Either create a LDIF file to add following attributes

  version: 1
  
  dn: dicomDeviceName=dcm4chee-arc,cn=Devices,cn=DICOM Configuration,dc=dcm4che,dc=org
  changetype: modify
  add: dcmCalculateQueryAttributes
  dcmCalculateQueryAttributes: TRUE
  
  dn: dicomDeviceName=dcm4chee-arc,cn=Devices,cn=DICOM Configuration,dc=dcm4che,dc=org
  changetype: modify
  add: dcmCalculateStudySizePollingInterval
  dcmCalculateStudySizePollingInterval: PT5M
  
  dn: dicomDeviceName=dcm4chee-arc,cn=Devices,cn=DICOM Configuration,dc=dcm4che,dc=org
  changetype: modify
  add: dcmCalculateStudySizeDelay
  dcmCalculateStudySizeDelay: PT5M
  

  and import it to the LDAP Server by using the ldapmodify command line utility.

  OR use the Add Attribute... and Add Value... function of Apache Directory Studio to add attributes on Device Level (e.g.: dicomDeviceName=dcm4chee-arc) of the Archive Configuration.

  Go to Configuration (page) -> Control (tab) in archive UI and reload the configuration.

Refer ISO-8601 Duration format for more know-how on Durations.

Verification

• Store studies to archive using storescu tool.
• Once the configured Calculate Study Size Delay and Calculate Study Size Polling Interval are reached, verify using Archive UI Navigation (page) -> Studies (tab) -> SIZE to view the calculated study size(s). Additionally, the same can be verified in the database tables study, series, study_query_attrs and series_query_attrs
