DDL for table & all its dependent objects

Question

Hi,
I'm trying to perform online_redefinition of a table in Oracle 11g. After this the depedent objects like indexes & Primary Keys & Foreign Keys are missing. Can anyone help with a detailed step by step procedure to perform this online_redefinition.
I've performed the below steps
1) check whether table can be redefined online or not.
2) create the duplicate empty table using CTAS where 1=2 condition.
3) start the online redefiniton.
4) do the interim sync.
5) end the redifinition.
6) drop the duplicate table.
Regards
Surya

Hi,
here are steps to consider:
1) check first if the table can be redefined online by using: DBMS_REDEFINITION.CAN_REDEF_TABLE
2) Create an intermediary table
3) Start the redefinition of the table using : DBMS_REDEFINITION.START_REDEF_TABLE
4) Copy  dependents from the original table to the intermediary table using: DBMS_REDEFINITION.COPY_TABLE_DEPENDENTS
5) synchronize between the original and intermediate table : DBMS_REDEFINITION.SYNC_INTERIM_TABLE
6) Finish the redefinition of the intermediary table using: DBMS_REDEFINITION.FINISH_REDEF_TABLE
7) compare the "new" original table (used to be intermediary  ) to the intermediary table (used to be old original)
8) Drop the intermediary table
I hope this helps you.
