Suffering from corruption in your database, it is nearly just as challenging as in real life…

The other day we suffered from a curruption in a 500+ Gigabyte database, as a sequentual dberify would take about 16+ hours I wrote this one below which starts the dbv’s in nohup in parallel. My dbv finished within the hour, system performance will drop though;)

[SYSTEM@DB01.REMIDIAN.COM]
SQL> l
  1  select
  2  'nohup dbv' ||
  3   ' file=' || file_name ||
  4   ' blocksize=4096' ||
  5   ' logfile=' || file_id || '_' || substr( file_name, instr(file_name,'/',-1) +1) || '.log &'
  6  from
  7* dba_data_files
