## Move the table
alter table clientscannedimage move; //move on segemnt
select owner,index_name,status from dba_indexes where table_name='CLIENTSCANNEDIMAGE'
alter index <index_name> rebuild>;

## If the move setting is low space then use it
select table_name,pct_free from user_tables order by 1
alter table clientscannedimage move pctfree 40;

## Detect & Analyze row chaining
-utlchain.sql //create table this script
--analyze table clientscannedimage list chained rows;
---select count(*) from chained_rows where table_name='CLIENTSCANNEDIMAGE'

----analyze table ldbo.clientscannedimage compute statistics;
-----select CHAIN_CNT from user_tables where table_name='CLIENTSCANNEDIMAGE'

Solution--------
create table temp_scannedimage
as select * from clientscannedimage
where rowid(select head_rowid from chained_rows where table_name='CLIENTSCANNEDIMAGE');

delete from emp
where rowid in (select head_rowid from chained_rows where table_name='CLIENTSCANNEDIMAGE');

insert into clientscannedimage select * from temp_scannedimage
