New security enhancements for OnDemand include tighter report data security, group profile
for administration security, and document selection lists that shows only authorized reports.
Spool File Archive supports AFP index fields, which can be defined in Data Description
Specifications (DDS).
Record Archive
Organizations can use IBM 3995 optical libraries to cost-effectively store aged data records,
such as historical sales or customer data. Users can continue to use existing applications,
which are functionally rich and familiar, with the added capability of retrieving historical data
from optical files and more current data from magnetic disk. Record Archive maximizes the
savings using optical (instead of magnetic) media for long data retention periods and offers
faster retrieval than tape archival.
Note: Although performance for optical retrieval is good, it should not be expected to be a
replacement for quick retrieval from disk.
OnDemand Record Archive is designed to minimize the magnetic storage space required to
keep track of these data records on optical:
• For quicker access, only pointers to the data are stored on magnetic disk.
• Actual data is stored on optical.
Using OnDemand Record Archive Application Programming Interfaces (APIs), existing
applications can be enhanced to store and retrieve records to and from optical files.
Programmers can avoid dealing with the internal details of creating, reading, writing, and
securing data on optical.
Object Archive
Organizations can compress and archive a variety of AS/400 objects, such as program
source files, database files, or entire application libraries, on tape or optical media. A
common use is to store monthly versions of purged detail records such as general ledger
transactions. Later, an individual version (called a “generation”) can easily be restored from
optical or tape media for research as needed. Note these points:
• Objects are compressed with more efficient disk space utilization than with standard
OS/400 save commands.
• Multiple generations of archived objects, such as monthly or annual detail files, can be
managed. Users simply specify which generation is to be retrieved and let OnDemand
manage the multiple copies.
