Solution :


To Check which objects or tables are locked

sql > SELECT OWNER,TABLE_NAME,STATTYPE_LOCKED
FROM DBA_TAB_STATISTICS
WHERE STATTYPE_LOCKED IS NOT NULL;


TO Unlock all the tables in a schema at once :

sql> exec dbms_stats.unlock_schema_stats('schema_owner');
e.g : sql> exec dbms_stats.unlock_schema_stats('apps');

TO Unlock all Individual tables in a schema at once

sql> exec dbms_stats.unlock_schema_stats('table_owner','table_name');
e.g : sql > exec dbms_stats.unlock_schema_stats('AR','AR_REV_REC_QT'); 

There are two reasons for that error message:

1 ) There are duplicate rows on FND_HISTOGRAM_COLS table for JE_BE_LINE_TYPE_MAP table.
Because of this problem, FND_STATS tries to gather histogram information using wrong command and it fails with ora-20001 errors.

Following SQL should have returned one row , not two.

SQL> select a.column_name, nvl(a.hsize,254) hsize
from FND_HISTOGRAM_COLS a
where table_name = 'JE_BE_LINE_TYPE_MAP'
order by column_name;

COLUMN_NAME HSIZE
------------------------------ ----------
SOURCE 254
SOURCE 254

2) Column does not exist on the table but still listed in FND_HISTOGRAMS_COL table.

Solution:
Find out all duplicates and/or obsolete rows in FND_HISTOGRAM_COLS and delete one of them.
Remember to take backup of the FND_HISTOGRAM_COLS table before deleting any data.

-- identify duplicate rows

select table_name, column_name, count(*)
from FND_HISTOGRAM_COLS
group by table_name, column_name
having count(*) > 1;


-- Use above results on the following SQL to delete duplicates

delete from FND_HISTOGRAM_COLS
where table_name = '&TABLE_NAME'
and column_name = '&COLUMN_NAME'
and rownum=1;


-- Use following SQL to delete obsoleted rows

delete from FND_HISTOGRAM_COLS
where (table_name, column_name) in
(
select hc.table_name, hc.column_name
from FND_HISTOGRAM_COLS hc , dba_tab_columns tc
where hc.table_name ='&TABLE_NAME'
and hc.table_name= tc.table_name (+)
and hc.column_name = tc.column_name (+)
and tc.column_name is null
);
