Rich,
1)Run following script to check fat size which will indicate how big your
initial extent may be as you are not finding contigous space in your
tablespace. when it ask for value give your tablespace name..
undefine table_space
set verify off
prompt This script provides a report useful for resizing datafiles
prompt You should perform a 'ALTER TABLESPACE tsname COALESCE' before
running
prompt this script to ensure you are getting all free space at end of the
file
accept table_space prompt "Enter a tablespace_name or all: "
select ddf.file_name,
dfs.file_id,
ddf.blocks,
(ddf.blocks*value)/1024/1024 file_size_mb,
dfs.block_id block_hwm,
ddf.blocks-dfs.block_id fat_blocks,
floor(((ddf.blocks-dfs.block_id)*value)/1024/1024)
fat_mb,
ceil(((ddf.blocks*value)/1024/1024 -
((ddf.blocks-dfs.block_id)*value)/1024/1024)) resize_to
from dba_free_space dfs,
dba_data_files ddf,
v$parameter
where v$parameter.name = 'db_block_size'
and (ddf.tablespace_name = UPPER('&&table_space')
or 'ALL' = UPPER('&&table_space'))
and dfs.tablespace_name = ddf.tablespace_name
and dfs.file_id = ddf.file_id
and dfs.block_id = (select max(block_id)
from dba_free_space
where file_id = dfs.file_id)
order by fat_blocks desc;
/
2) Coalesce your tablespace and run this script again..
3) or reduce yr initial extent size and don't use parallel clause
HTH,
Regards
Rafiq

Hi all,
On 8.1.7.2.0 on HP/UX 11.0, I need to create an index online. So, I see how
much space I have:
select max(bytes/1024/1024)
from dba_free_space
where tablespace_name = 'MY_IDX_TS';
...and it returns "147.3475". So I create my index:
CREATE INDEX myschema.mycoolidx
ON myschema.mycooltbl(mycoolcol) PCTFREE 15
STORAGE(
INITIAL 140 M
NEXT 30 M
)
NOLOGGING ONLINE TABLESPACE my_idx_ts PARALLEL 2;
But I keep getting "ORA-01658 unable to create initial extent in MY_IDX_TS",
even though there is ample room. I thought it was because I had originally
tried it with "PARALLEL 2" and there was some overhead needed, so I
coalesced the TS (DICTIONARY, obviously) and tried it without the PARALLEL
to no avail. I've even dropped the INITIAL down to 130M without luck (again
after coalescing). Oh, to be LOCAL...
So, how big can I make the initial extent? I don't remember running into
this before and I can't find anything on MetaLink. And of course, I killed
the session when it was creating it so now I can't drop the index without a
ORA-8104 error.
Anyone?
TIA!
