i am transfering data from sqlserver 2005 to oracle 11xe r2.
using ogg112101_ggs_Windows_x86_ora11g_32bit " ogg for oracel",
and V34016-01 "ogg for sqlserver".
i have tabel and cols at both the end with out data.
step 1 making odbc conn to mssql
step 2 loginin into sqlserver ogg (ggsci) then making add trans data enable for the table.
step 3 make defgen pramater file for defgen tool.
step 4 defgen paramfile c:\gg\dirprm\defgen.prm
step 5 coping to target machine's dirdef folder of ogg for oracle.
these process are transfering my data from source to target.
my question is , is trans data command for each table is really required ?
becasue i have used this command for few tables they are also transfering
and i have left few tables but these tables are also transfering data.
i do not have any problme in running this command , i will run it , but i would like to know if it is relally required (even in future)then only i would like ot use it
if it is good practice then also i will use it .
INSERT and DELETE operations will be replicated even if you do not add trandata.However, if you UPDATE a non-key column of a table it will only be replicated to the target table if the trandata is added for that table.
You can test it.
