Hi,
I want to eliminate a row migration and row chaining in my table but an error occur when a list a chained rows. My script is like this

SQL> connect sys/change_on_install@kintana as sysdba
Connected.
SQL> analyze table rran.lots_de_travail1 compute statistics;

Table analyzed.

SQL> select num_rows, chain_cnt from dba_tables where table_name = 'LOTS_DE_TRAVAIL1';

NUM_ROWS CHAIN_CNT
---------- ----------
868050 238

SQL> analyze table rran.LOTS_DE_TRAVAIL1 list chained rows;
analyze table rran.LOTS_DE_TRAVAIL1 list chained rows
*
ERROR at line 1:
ORA-01495: specified chain row table not found

How to fix this error.

Regards.
