Hi All

We have our db patched to 11.2.0.2.3

Reuse redo entry

I ran the qry below for related file id and block

Select owner, segment_name, segment_type, partition_name,tablespace_name
From dba_extents
Where relative_fno = &1
And &2 between block_id and (block_id+blocks-1);

did analyze table schema.table_name validate structure cascade ; for that object

I need to know wht is cause of this message 'index undo for leaf key operations'

is it tablespace issue for the index
