Planning the Oracle Solaris Cluster HA for Agfa IMPAX Installation and Configuration

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

Configuration Restrictions

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

---

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 Oracle Solaris Cluster Data Services Planning and Administration Guide.

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

For performance — related 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 Agfa IMPAX application, but also the functionality of the connected modalities and viewing stations.

Configuration Requirements

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

---

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 Oracle Solaris Cluster Data Services in Oracle Solaris Cluster Data Services Planning and Administration Guide.

Installation Requirements

Agfa IMPAX must be installed according to the installation notes that are supplied by Agfa for your specific version of Agfa IMPAX. You must contact an Agfa consultant to install the Agfa IMPAX software. This is a requirement for the cluster to be supported by Agfa and Sun.

Dependency on Oracle Solaris Cluster HA for Oracle

Oracle Solaris Cluster HA for Agfa IMPAX depends on the Oracle Solaris 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 Oracle Solaris Cluster HA for Oracle to Support Oracle Solaris Cluster HA for Agfa IMPAX contains details about the requirements for configuring Oracle Solaris Cluster HA for Oracle.

Additional Libraries

Oracle Solaris Cluster HA for Agfa IMPAX requires the libraries that are provided in the /opt/SUNWscpax/impaxapp/util/ directory. These libraries enable the Agfa 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.

---

Caution - In Oracle Solaris Cluster 3.2, the libraries are changed. A similar library is included in the Oracle Solaris Cluster 3.2 distribution that has a better coverage of the functionalities needed to obtain the hostname and translate it into the logical hostname needed to operate in Oracle Solaris Cluster.

Configuration Planning Questions

Use the questions in this section to plan the installation and configuration of Oracle Solaris 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 Oracle Solaris Cluster Data Services Planning and Administration Guide.

• Which resource groups will you use for the Oracle Solaris Cluster HA for Agfa IMPAX application resource and the logical hostname resource?

• What is the logical hostname for the Oracle Solaris Cluster HA for Agfa IMPAX resource? Clients access the data service through this logical hostname.

• Where will the system configuration files reside?

  See Configuration Guidelines for Oracle Solaris Cluster Data Services in Oracle Solaris Cluster Data Services Planning and Administration Guide for the advantages and disadvantages of using the local file system instead of the cluster file system.
