10g to 11g upgrade using 11g rat

CASE STUDYUsing 11g Real Application Testing to analyse the impact of making the following changes:1) Upgrade the database from 10g to 11g2) Conert from single instance database to a two node RAC database!) Conert from file system based storage to 11g A"#Overview of Real Application Testing$ne of the best new feat%res in $racle 11g is the Real Application Testing option which enables %s to test the res%lt of a change witho%t act%ally implementing the samein a prod%ction enironment& Changes s%ch as database ersion %pgrades' optimi(er changes' hardware and storage changes all carry with them an element of risk and %ncertainty& Using this feat%re m%ch of that %ncertainty and g%esswork can be aoided&Real Application Testing comprises of two components:a) )atabase Replayb) "*+ ,erformance Analy(er -",A) ",A enables %s to test the impact of a change at the leel of a partic%lar "*+ statement to see if any improements or regressions occ%rred in the e.ec%tion of the "*+ statement beca%se of the change& )atabase Replay enables %s to capt%re workload real time in a prod%ction enironment and then replay the same in a clone or copy of the changed prod%ction enironment with the e.act timings' conc%rrency and transaction characteristics fo%ndin the original workload& The A/R comparison and )atabase Replay reports can easily help %s pinpoint any potential problems and errors as well any diergence in performance&This feat%re will afford b%sinesses increased confidence and s%rety when faced with a system change as well as significantly red%cing the costs as well as reso%rces associated with the testing phase&)atabase Capt%re is now s%pported in ersions 0&2&0&1 as well as 10&2&0&! and 10&2&0&2enabling %s to test the impact of %pgrades from both 0i as well as 10g to 11g& 3ote' howeer' that replay can only be performed in a $racle 11g database&At a ery high leel' the database capt%re and replay will inole the following steps:1) ,repare the so%rce database for capt%re2) Capt%re the workload!)
