Answer / andy vaidya
SQL Loader (sqlldr) is a bulk loader utility from Oracle
for loading data into Oracle tables where as DataStage OCI
(Oracle Call Inteface) is a passive stage that connects to
any Oracle Database and collects necessary data and passes
it on to Datastage ETL for processing and applying
transformation where necessary and loads into target table.
DataStage OCI offers input and output stages for
conveniently connecting to Oracle Source databases and
Target Oracle databases.

Answer / roshan nayak
An addition of above info through sqlldr we load bulk data
for this we use ora bulk stage. In this we load data
through script so data loaded in form of package. But there
is some restriction also, when we load data (bulk) target
table should not have index. We generally load data in
table-partation like weekly,monthly. It is faster than OCI.
Where as through OCI we load data as sequence manar. we can
set buffer size as require to read or write data. Here no
need to remove index from table.
