    take scn from standby and start take incremental bkp from primary and ship incremental backup from primary to standby and then do start mrp on standby.

    Prerequisites:
    We need to check the MRP process status.
    If the mrp process starts status &may network issue also main region not applied to standby DB. We need to check SD archives if they are not available then we need to take incremental backup using SCN based on standby database

    without pfile or spfile we can not mount our database..why is he thinking so much..interviewer is asking basics only..its bit easy as i am having 2.3 years of experience

    • @RACSINFOTECH
      @RACSINFOTECH  ปีที่แล้ว +1

      In the interview sometime we may not recall simple things also it’s human nature.. no worries .. the guy who’s given this mock interview he got the job in mnc with very good package 😀 .. generally interviews are simple only, once got the work that’s tough 😁

      We required control file to move database into mount state.. it's not spfile or pfile.
      Spfile and pfile are required when database starting from shutdown to no mount state

    in general what is the salary range ??
    for 3 -4 years
    and for 5 - 6 years
    can any one reply

    • @RACSINFOTECH
      @RACSINFOTECH  หลายเดือนก่อน +1

      It’s depends on current salary,.. we can expect 30% *hike on current CTC..
      Generally I will calculate the salary in this format.. with 4 years experience salary should be 4*2+2= 10 lakhs * minimum.. it’s my point of view.. it’s individual choice/ options how much they want few of them will get less pay few of them will get more than which i mentioned.. so take your call***
