SUBJECT: Possible System Downtime
AMIGOS has learned from OCLe that the on-line system will
probably not be available on the following Saturdays: August
20, August:17 and September 3. When these dates are firm an
announcement will appear on the screen as well as in an OeLe
Newsletter. Even though the dates are not certain, we wanted
this information available to you for Saturday schedule
planning.
It is necessary to suspend on-line operations for the installation
of a multi-level indexing technique that will
reduce accessing time for derived search keys. This two-level
indexing will reduce the number of input/output (I/O) transactions
required to retrieve records. At the same time OeLe
will be separating holding bits from the bibliographic records
for storage purposes. The holding symbols will continue to
display at the end of the bibliographic record, but this
separation will remove the limitation of the number of holding
symbols that could be attached to a single record.
