Sun Cluster Data Service for Agfa IMPAX Guide for Solaris OS

Planning the Sun Cluster HA for Agfa IMPAX Installation and Configuration

This section contains the information that you need to plan your Sun Cluster HA for Agfa IMPAX installation and configuration.


Note –

Before you begin, refer to your Agfa IMPAX documentation and consult your Agfa consultant for configuration restrictions and requirements that are not imposed by Sun Cluster software.


Configuration Restrictions

The configuration restrictions in this section apply only to Sun Cluster HA for Agfa IMPAX.


Caution – Caution –

If your data service configuration does not conform to these restrictions, the data service configuration might not be supported.


For restrictions that apply to all data services, see the Sun Cluster Data Services Planning and Administration Guide for Solaris OS.

Connections between the database and Agfa IMPAX are not resilient. To ensure integrity, do not configure Oracle for a local failover. Instead, use Sun Cluster's capacity to fail over to another cluster node.

For performance reasons, install the database files on a highly available local file system. Do not install database files on the cluster file system. The resulting degraded performance could affect the functionality of not only the IMPAX application, but also of the connected modalities and viewing stations.

Configuration Requirements

The configuration requirements in this section apply only to Sun Cluster HA for Agfa IMPAX.


Caution – Caution –

If your data service configuration does not satisfy these requirements, the data service configuration might not be supported.


For requirements that apply to all data services, see “Configuration Guidelines for Sun Cluster Data Services” in Sun Cluster Data Services Planning and Administration Guide for Solaris OS.

Installation Requirements

Agfa IMPAX must be installed according to the installation notes that are supplied by Agfa for your specific version of Agfa IMPAX. A consultant from Agfa always installs the Agfa IMPAX software. This is a requirement for the cluster to be supported by Agfa and by Sun.

Dependency on Sun Cluster HA for Oracle

Sun Cluster HA for Agfa IMPAX depends on the Sun Cluster HA for Oracle data service and uses an HAStoragePlus resource to synchronize startup of this database resource. When your Agfa engineer installs the Agfa IMPAX software, the engineer also installs the Oracle software. Configuring Sun Cluster HA for Oracle to Support Sun Cluster HA for Agfa IMPAX contains details about the requirements for configuring Sun Cluster HA for Oracle.

Additional Libraries

Sun Cluster HA for Agfa IMPAX requires the libraries that are provided in the /opt/SUNWscpax/impaxapp/util/ directory. These libraries enable the IMPAX application to be used in a cluster. Additionally, some scripts must be replaced in the installation. The Agfa documentation contains the details about these scripts.

Configuration Planning Questions

Use the questions in this section to plan the installation and configuration of Sun Cluster HA for Agfa IMPAX. Write the answers to these questions in the space that is provided on the data service worksheets in “Configuration Worksheets” in Sun Cluster 3.1 Data Service Planning and Administration Guide.
