Re: downtime optimization for system copy

$

Hi,

 

May I ask a basic remark: if you perform an homogeneous system copy (same oS & same DB), you don't need to perform en R3load export/import.

Better way, is :

  1. Copy source datafiles to target (traditional backup/restore)
  2. Rename/Restart target DB
  3. Compress target DB
  4. Reduce target FileSystem

 

Pro :

- no perf impact of source

- you can compress online (open for end users)

 

Cons :

- need more temporary space .. to be compared with used space for R3load epxort

 

Regards
