Any scope for using transportable tablespaces ?
Even if you have to transport more than you want then drop the excess objects
after the tablespace(s) arrive.

Subject: Copy Big Table from one Db to another
Did anyone has done any benchmark and has created any details on the best
method to copy a big table from one DB to another. I am looking for a 2-5 Tb
tables to be moved within the same ASM storage or can say that these different
databases share the same ASM disk group. Some options like
1. expdp/impdp - with optimization like parallel or so
2. Using DB Link and Insert Append
3. Using Copy command
4. Using sqlcl or other Oracle tool
Tables have multiple LOBs object and it is not partitioned. Any initialization
parameter setting like increasing PGA for Direct operation or tweak that can
save the time
TIA
Sanjay
