Accessing Multiple Own Archive Instances

Overview

In a scenario wherein multiple archive instances are connected to a shared LDAP and/or database, it may become necessary to monitor / use the archive instances of such a clustered setup from one archive instance node.

Configuration

Since it is a shared LDAP setup, the configurations done for each of the archives shall be available to all other archives (in the cluster) on startup. If not, clone archive 1 and change the device name, Network Connections, AEs and Web Applications of the cloned archive device(s).
By default the dcm4chee-arc archive device does not have any http or https Network Connections configured. To be able to access web services of other archives in the cluster from dcm4chee-arc archive device, one will have to add these http and/or https Network Connections.

Assuming the cloned archive device as dcm4chee-arc-2.

Using Archive UI

Go to Configuration -> Devices -> dcm4chee-arc-2 -> Child Objects -> Network Connections and Add new Network Connections.
Set Name as http, provide values for Hostname and Port where this dcm4chee-arc-2 archive device's http connection is listening and Save.
Go to its Network Connection Extension and set Protocol as HTTP.
Repeat the steps for https, if one wants to access dcm4chee-arc-2 archive device web services also with secured http.
If the dcm4chee-arc device was cloned, the web applications also are cloned to the new device. But one has to go to individual web applications and change the Web Service Path and AE Title to reflect the new AETs of the cloned device. For eg. go to Configuration -> Devices -> dcm4chee-arc-2 -> Device Extension -> Child Objects -> Web Applications -> DCM4CHEE_CLONE; change the Web Service Path from /dcm4chee-arc/aets/DCM4CHEE/rs to /dcm4chee-arc/aets/DCM4CHEE_CLONE/rs. Also associate AE Title as DCM4CHEE_CLONE and Save.
Repeat the above step of associating AET of cloned device for DCM4CHEE-WADO_CLONE Web Application in the dcm4chee-arc-2 device.

Using LDAP

One may either

create a LDIF file (e.g.):

  version: 1
  
  dn: cn=http,dicomDeviceName=dcm4chee-arc-2,cn=Devices,cn=DICOM Configuration,dc=dcm4che,dc=org
  objectClass: dicomNetworkConnection
  objectClass: dcmNetworkConnection
  dicomHostname: localhost
  cn: http
  dcmProtocol: HTTP
  dicomPort: 8780
  
  dn: cn=https,dicomDeviceName=dcm4chee-arc-2,cn=Devices,cn=DICOM Configuration,dc=dcm4che,dc=org
  objectClass: dcmNetworkConnection
  objectClass: dicomNetworkConnection
  dicomHostname: localhost
  cn: https
  dcmProtocol: HTTP
  dicomPort: 8743
  
  dn: dcmWebAppName=DCM4CHEE_CLONE,dicomDeviceName=dcm4chee-arc-2,cn=Devices,cn=DICOM Configuration,dc=dcm4che,dc=org
  objectClass: dcmWebApp
  dcmWebAppName: DCM4CHEE_CLONE
  dcmWebServiceClass: WADO_RS
  dcmWebServiceClass: STOW_RS
  dcmWebServiceClass: QIDO_RS
  dcmWebServiceClass: QIDO_COUNT
  dcmWebServiceClass: DCM4CHEE_ARC_AET
  dcmWebServicePath: /dcm4chee-arc/aets/DCM4CHEE_CLONE/rs
  dicomAETitle: DCM4CHEE_CLONE
  dicomDescription: Hide instances rejected for Quality Reasons
  dicomNetworkConnectionReference: cn=https,dicomDeviceName=dcm4chee-arc-2,cn=Devices,cn=DICOM Configuration,dc=dcm4che,dc=org

  dn: dcmWebAppName=DCM4CHEE-WADO_CLONE,dicomDeviceName=dcm4chee-arc,cn=Devices,cn=DICOM Configuration,dc=dcm4che,dc=org
  dicomDescription: Hide instances rejected for Quality Reasons
  dcmWebServiceClass: WADO_URI
  objectClass: dcmWebApp
  dicomAETitle: DCM4CHEE_CLONE
  dcmWebAppName: DCM4CHEE-WADO_CLONE
  dcmWebServicePath: /dcm4chee-arc/aets/DCM4CHEE_CLONE/wado

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) in the Archive Configuration.

Refer Network Connection and Web Application to understand the description of attributes.
