Presentation

Script $gvsqw_SybBin/sqwsyb_UpdtStatsParallelDatabase.ksh :


update index Statistics in parallel
use the command 'update index Statistics $lvsqw_Owner.$lvsqw_Table'
compute Statistics on all indexed columns
you can also force delete with 'delete Statistics $lvsqw_Owner.$lvsqw_Table'
dynamically calculates a sample to put option 'with sampling=$lvsqw_SamplePct percent'
