Folks
1 more issue
There exist 2 Target partitions each of Size 400 GB in which the
respective 700 GB Table needs to be exported using Datapump.
Additionally a High Value of PARALLEL parameter is preferred to Speed up
the 700 GB Export.
What Value of PARALLEL is Advisable for an 8 CPU machine connected to an
EMC Storage Box?
Are the following parameters & Syntax Advisable? If so, will it restrict
the PARALLEL parameter specification to a MAX value of 2 only?
DUMPFILE=/Partition1:Tbl_Part%U.dmp, /Partition2:Tbl_Part%U.dmp
FILESIZE=350G
PARALLEL=8
Can /Partition1 & /Partition2 be explicitly Specified? I am unable to
follow the meaning of the word "directory_object"
Is the Directory Object an Environment Variable which needs to be set on
the O.S.?
Cheers

Using Datapump need to export & import a 700 GB Table having a LONG
Column (containing JPEGs).
Any Rough Estimate on Time needed for the same?
What best practices / parameters are Advisable to speed up the same?
Any Links will help.
Config:-
Oracle 10gR2
Solaris 10
SunFire - 8 CPUs
RAM 32 GB
