PROBLEM:

While analyzing the table for chained rows, got below error. ORA-1495

ANALYZE TABLE SCOTT.EMPTAB LIST CHAINED ROWS;
*
ORA-1495  specified chained row table not found

SOLUTION:

To fix it run the utlchain.sql script.

sqlplus / as sysdba
$ORACLE_HOME/rdbms/admin/utlchain.sql script

After that

TRUNCATE TABLE CHAINED_ROWS;
ANALYZE TABLE SCOTT.EMPTAB LIST CHAINED ROWS;
