Media and Resource Management

The media and resources available for use by the IOA Archive server are defined by installation parameters in member IOASPRM. The definition of media and resources differs for various media types, but includes the following:

• Media information (name, type, and so on.)
• Information about each resource (device, session, and so on) known to the server and the desired status of the resource when the server is started.
• An owned or shared flag (dedicated versus dynamic) which indicates if the resource is dedicated to the server, or is dynamically assigned when needed and released when no server requests are pending.

Note: Non-dedicated resources may degrade response time if insufficient resources are available for the IOA Archive server when required.

The initial status of resources defined in the installation parameters can be changed during processing by operator commands.

Resources required for the IOA Archive server should be online and ready when requested. Services provided by the IOA Archive server degrade or stop if a required resource is not available. In this case, users requesting online viewing or immediate printing may be left waiting for data from migrated CDAM datasets.
