Opticonnect For Iseries (5722-Ss1 Options 22, 23) - IBM i series Handbook

Operating System/400 (5722-SS1)
An API is provided to handle the interruption that occurs when an application tries to open a
database file that has been migrated to off-line media. The API enables an on-demand recall
of a database file from offline media to DASD and resumption of the application. Application
changes are not required.
These APIs provide support to use or build applications to manage tape usage and the recall
of data from offline media to DASD. This feature is a prerequisite feature to Backup Recovery
and Media Services for iSeries (BRMS/400) (5722-BR1). It is also required when developing
Hierarchical Storage Management (HSM) dynamic retrieval functions.

OptiConnect for iSeries (Option 23)
OptiConnect for iSeries provides high-speed transparent access to data through fiber optic
bus connections and performance enhancements to iSeries Distributed Data Management
(DDM).
The mechanism used by OptiConnect for iSeries to access database files on connected
systems is modeled after DDM. Just as DDM uses a DDM file and APPC communications to
redirect file access operations, OptiConnect for iSeries uses DDM files and a specialized
transport service to redirect file access operations to a target system.
Because OptiConnect for iSeries operates only among systems sharing the same bus
(connected with fiber optic cables), it can achieve transport efficiencies not possible with
more general purpose, wide-area communications protocols.
With OptiConnect for iSeries customers, can offload the database application CPU cycles of
up to 13 iSeries servers.
The major advantages of OptiConnect for iSeries are realized by customers who are rapidly
approaching system capacity limits, and/or who intend to implement distributed database
application servers within a data center or short-distance campus environment. Customers
planning to implement distributed application servers can also benefit from using
OptiConnect for iSeries.
When used with the Object Connect for iSeries facility, OptiConnect for iSeries provides a
high-efficiency migration aid for the iSeries Advanced Series.
