l_agent
A record is stored in the database for each unique key as determined from Table D-1. For example,
if an agent is moved to another supervisor within an interval, then two records exist for that agent
ID within the interval since the two supervisor IDs cause two distinct keys (with all other portions
of the key being identical).
A record only exists if there is data associated with the key. For example, if no calls are processed
in a particular group within an interval, then no i_accddn record will be stored in the database for
that group in that interval. This means that during periods where there is no switch activity or link is
down, no records are stored in the database. Reports generated will not contain data for this time
period.
The database is pre-allocated using the database storage calculator. It is allocated with enough
space to handle the storage parameters specified. Additionally, the database is compressed to max-
imize storage potential. The average compression ratio of 54% is reflected in storage calculator
values.
The overhead for a boot disk is 350 Mbytes. The overhead per partition is 50 Mbytes.
The database storage calculator pre-allocates disk storage for historical data based on parameters
supplied in the storage calculator screen. The values in Table D-2 are determined and are refer-
enced for computing disk storage requirements.
