 This has probably been discussed before but I would like to know if a full
 database
 export could affect either Oracle or server performance.

Of course it can affect performance, but I think it depends on your hardware
and the system activity in the moment of the export as well


 Also, does a consistent=y export only mean that each table is consistent
or
 is the
 entire database consistent?

It means that the tables exported are consistent to each other.

(The data within a table exported is always consistent independientely of
the consistent option used.)

RE: Oracle Exports and performance

2002-03-20 Thread Ball, Terry

Just one comment.  Back on O7, some testing was done by one of the DBAs
where I used to work.  He determined that the consistency was within a
schema, not the whole export.  SO if you had cross references between
schemas, you could experience problems on imports. 

I don't know if this functionality continued to 8, 8i or 9i.
