Home -> Community -> Mailing Lists -> Oracle-L -> RE: Ora-1654 Unable to extend index on tablespace
Mitchell,
I may well be wrong but check your db_block_size in v$parameter
eg
select name, value
from v$parameter
where name = 'db_block_size'
/
NAME VALUE
I think you have to multiply the reported figure by the blocksize to get the extent size being looked for.

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;
TABLESPACE_NAME FREE_SPACE SEGCOUNT TOTALOFSEGMENTS
------------------------------ ---------------- -------- ----------------
IDX_FINC_C70614 4,096 1 4,096 IDX_FINC_C70614 24,576 6 147,456 IDX_FINC_C70614 28,672 1 28,672 IDX_FINC_C70614 364,544 1 364,544 IDX_FINC_C70614 368,640 2 737,280 IDX_FINC_C70614 1,396,736 1 1,396,736 IDX_FINC_C70614 2,801,664 1 2,801,664 ---------------- TOTAL of SEGMENTS 913,092,608
Mitchell have you tried coalescing your tablespace? How big are your extents?

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.
