Why do you want to open row movement? Flashback table will definitely cause ROWID to follow.

Flashback table will definitely cause ROWID to follow the changes, why to open row move, that's why

Now I'll do an experiment to verify:
Sql> drop tablespace TP2 including contents and datafiles;
Tablespace dropped.
sql> Create tablespace tp2 datafile '/u01/app/oracle/oradata/tp2.dbf ' size 512K;
Tablespace created.
sql> CREATE TABLE t1 (ID int,name char ()) tablespace TP2;
Table created.
Sql> begin
2 for I in 1. 1000 loop
3 INSERT INTO T1 values (i, ' Gyj ' | | i);
4 End Loop;
5 commit;
6 end;
7/
Pl/sql procedure successfully completed.

Check rowid.
Sql> Select Rowid,id from t1 where Id>=1 and id<=5;
ROWID ID
------------------ ----------
AAASVNAAIAAAAAOAAA 1
Aaasvnaaiaaaaaoaab 2
AAASVNAAIAAAAAOAAC 3
Aaasvnaaiaaaaaoaad 4
AAASVNAAIAAAAAOAAE 5
Sql> ALTER TABLE T1 enable row movement;
Table altered.
Sql> select Current_scn from V$database;
Current_scn
-----------

sql> Delete from t1
1000 rows deleted.

Commit complete.

Insert a large number of records to allow space to run out
Sql> begin

3 INSERT INTO T1 values (i, ' Gyj ' | | i);

Sql> Flashback table T1 to SCN 6177172;
Flashback complete.

Check the original 1000 rows of the first 5 lines of ROWID, and the original ROWID is not the same
Sql> Select Rowid,id from t1 where Id>=1 and id<=5;
ROWID ID

Check the original 1000 line records the first 5 lines of the file number, block number, line number, and the original block number line number is not the same
Sql> select Id,dbms_rowid.rowid_relative_fno (ROWID) File#,dbms_ Rowid.rowid_block_number (ROWID) block#,dbms_rowid.rowid_row_number (ROWID) row# from T1 where Id>=1 and id<=5;

        5       &N Bsp  8     &NBSP;          367

I did this experiment to make the table space a little bit more convenient to observe, in the T1 table first add 1000 records, and then delete, and then insert some records into the inside until the time to take up the space, so that the last new inserted records will occupy the original 1000 records space ...

Complete!
