Hi DBAs
Whenever I have the ora-1654, I
will
1. alter index/table name deallocate unused
2. alter tablespace name coalescs;
3. run querys to check dba_free_space
and dba_data_files
There are total 140 indexes on this tablespace
with setting init 1024k and next 1024k.
I got confused now that for message 'unable to extend by 256'. What is mean for 256
here?
The free space(byte) must be over 1024k
here to avoid ora-1654 for each of 140 index segments?
Thanks in advance.
Mitchell
This the query I run today. I only take
first few lines and last few lines.
compute sum LABEL 'TOTAL of SEGMENTS' of
totalofsegments on report
select tablespace_name, bytes free_space,
count(bytes) segcount,
(bytes *
count(bytes)) totalofsegments
from dba_free_space
where
tablespace_name=UPPER('&1')
group by tablespace_name,
bytes
order by tablespace_name, bytes;

Mitchell have you tried coalescing
your tablespace? How big are your extents?

Subject: Re: Ora-1654 Unable to extend index on
tablespace
Dear DBAs
I have a tablespace for
index with 5 file with different size from
500mb - 2000 mb.
Total tablespace size is 6g and used
5317mb abote 86.13% usage.
I got the error
today.
ora-1654
unable to extend indx sechma.indexname by 256 in tablespace
tablespacename.
The following is the query I got for the
tablespace .
We can see the index takes 92 extents and
maxextends setting is 8192.
I then set
autoextend on a datafile then error is gone.
What is the reason to cause ora-1654 even there
are 700mb space avai. I also
checked
the tablespace and index setting with both have next extend 1024k,
maxextend 8092.
