One of the option is to create SSIS package:

For simplicity and to setup script to rerun this automatically on demand. I would go with following steps.

Method 1.
------------
1. Oracle side = Using SQLPLUS query the tables and spool the data as comma delimited file.
2. SQL server side = Using bcp utility load the data into SQL server tables.

or

Method 2.
------------
1. Oracle Side = Using SQLPLUS spool the data with "insert into table ..." string along with data.
2. SQL server side = Run the above generated file from ISQL and insert data directly into the SQL server.

yes... i have the similar screen... but with oracle 10g [not 11g]

when you say "Use Oracle Net Manager to configure the connection to the oracle server" what does it mean?
i already have the default TNS listener configured

also... what is this SSMA thing? is it any good/better than what you are teaching me?

AmmarR

10g should work fine.

oracle net manager actually configures you tnsnames.ora file.

so if you can manually configure the file, then why bother with net manager,

just make sure the entries in the tnsnames.ora file are formatted properly like below
and it should work fine

------------------------------------
# TNSNAMES.ORA Network Configuration File: C:\oracle\ora92\NETWORK\ADMIN\tnsnames.ora
# Generated by Oracle configuration tools.

ServerName =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.2.0.7)(PORT = 1521))
)
(CONNECT_DATA =
(SID = ServiceName)
)
)

As mentioned by sridharv9, i would prefer the simple and normal method of SSIS,

i tried SSMA before with sybase, and its wasn't as easy and as smooth as they claimed it would be, there are few challenges and pre-configurations that you need to setup before using it.

but if you want to read more about SSMA and try it your self here are useful links
