Cluster linking prerequisites

The following table summarizes the configurations to perform before linking one cluster to another in a multiple IMPAX cluster configuration.

Area to configure	Summary of tasks
Host tables	Host tables on all IMPAX Clients, IMPAX Servers, Connectivity Managers, and modalities must match.
Sources	All sources must be unique and configured correctly. Sources must HIS verify all incoming studies against the Patient ID and Accession Number. Department and Institution Names must be set correctly. The station_name must be unique across all clusters. Archiving must occur for the correct modalities. The data center (or hub) must be configured with all sources from all data center and entity (or spoke) sites.
Network devices	All IMPAX network devices must be configured correctly with unique AE titles. Each cluster must know about other IMPAX clusters' network devices. All data center and entity sites must know about all the other sites.
Body Part Manager	For a consistent presentation of data, Body Part Managers across the cluster must contain the same entries.
Specialty Mappings	For a consistent presentation of data, Specialty Mappings across the cluster must contain the same entries.
Report sources	To improve the workflow when using a central report repository, a default report source can be defined in the IMPAX Business Services (installed on the Application Server).
Institution and department names	The station_name must be unique across all clusters.
Demographic layouts	To ensure that the look of studies is the same throughout the linked cluster, set the demographic layouts for each source to be the same throughout all linked clusters for both printing and displaying.
Prefetching rules	If prefetching rules differ between clusters, users will get different relevant priors at different sites.

Also ensure that all Connectivity Manager servers used are correctly configured at each site.

When clusters are linked, enterprise search locations can be defined in the IMPAX Client Configure area. These locations can then be added to the Enterprise search option as appropriate. As well, users can select whether or not the enterprise is searched when the Text area is opened.
