Understand the same Query between Between 2 databases on servers differents

edited Nov 30, 2017 4:01PM in SQL Performance (MOSC) 13 commentsAnswered

hello Gurus,

    I have a simple query : "select count(*)  from gl_balances;" that i execute between 2 environments. ServerTest (OACNPRE) (8 cpu ) and Serverprod(OACNPRD).(16 cpu).

the only difference is :  db file sequential read 0.78 serverTEST and  94.40 serverProd then i suppose it is a problem ressource system for access file system.

Then  To improve it in my serverPROD, i have executed my query  by creating SQL_PROFILE "query parallel DOP 32".

Therefor i would like know what are the parameters that i have to increase for improve the "wait time for db file sequential read" without create sql_profile ?

or what are the parameter i have to update that my query will be executed in mode parallel ?
