Databases vs. Storage Areas Why six databases? – Previous processor issues – Administrative ease (dump & load, idxrebuilds, etc.) Why storage one database? – Ease in tuning – Data affinity in cache – Not for every version 8 database What are storage areas? – Logical database “areas” – Separate database schema from data – Restores ease of administration (dump&load, etc.)

Version 9 Data Files Data files (dbname_sa#.ext#) – Data Storage Areas (trhead, trlines, trother, trsm, trstat, trtrans, trcust) – Index Storage Area (trhead_idx, trlines_idx, trother_idx, trsm_idx, trstat_idx, trtrans_idx, trcust_idx) Before Image file – nxt.bi, nxt.b1,... Log file - nxt.lg License file - nxt.lic Lock file – nxt.lk

Version 9 Data Files nxt.db nxt_7.d1 nxt_7.d2 nxt_8.d2 Nxt_8.d2 nxt_19.d1 nxt_19.d2 trhead trhead_idx nxt_19.d1 nxt_19.d2 trcust trcust_idx nxt.bi nxt.b1 nxt.b2
