Mistakenly I added lot of datafiles with autextend on option.. I realized later and then tried to resize the datafiles to a minumum space but got the below error
ORA-03214: File Size specified is smaller than minimum required.
How to resolve this problem to reclain the space back?

View 1 Replies View RelatedHow to check for the increment of a space of the tablespace based on the particular table. (i.e.) Say a scenario, if am trying to load the data for a particular table, for first I loaded some 10000 records and then again loading 50000 records ,so based on the icrement of the reocrds the tablespace size also increases gradually . so for this scenario how to monitor the increment of the space.

We are using Oracle 10g and have 10 tablespaces defined for our Database which have 108 tables. Size of 108 tables is around 251 MB as seen during importing the dump. While creating these 10 tablespaces I used below parameters for allocation of space
SIZE 1M REUSE AUTOEXTEND ON NEXT 1M MAXSIZE 1M;
which set the initial space for 10 tablespaces to around 1032Kb each. Now my Question is after importing the dump , how the disk space for 10 tablespaces increases to 398 MB in total ?
Is there any relation of Tablespace disk space and Actual Data present in the tables ?

My question is what are the advantages and disadvantages having one single tablespace versus multiple tablespace?
Easy to maintain when you have single tablespace. but hard to track the IO issues if you have one single tablespace.
I have one database which is recently upgraded from oracle 8.1.5 to oracle 10.2.0.4.The database is having around 300 tablespace and total size of the database is 1.5 TB.
The database was created in oracle 8i and all the teblespace were DMT(Dictionary Managed Tablespace) .Usually after up gradation all the tablespace are in DMT mode. Now my requirement is to convert all the tablespace into LMT (Locally Managed Tablespace) so that I can AVAIL ALL THE FEATURES OF LMT.
This database is a mission critical database and very less downtime can be allowed.
Is there any way I can calculate percentage of space used in a block.Eg if a table size is 100 blocks,How Can I check the percentage of used space in block.

I have several questions on reclaim space:
1. It seems that segment adviser give a really cool view to know which segment should be shrink and how much size will free up after shrink. But actually, this need a very a job or manually do this. I have once heard about some query from can estimate this :
A script from MOS, but actually I found this it's not very accurate with segment adviser. This script should report the real space the table occupy, but after shrink space, the space doesn't free up.
SELECT TABLE_NAME , (BLOCKS *8192 / 1024/1024 ) - (NUM_ROWS*AVG_ROW_LEN/1024/1024)
"Data lower than HWM in MB" FROM DBA_TABLES WHERE UPPER(owner) =UPPER('&OWNER') order by 2 desc;
Also there is a script evaluate the tablespace fragments from some people:
SELECT tablespace_name,
SQRT (MAX (blocks) / SUM (blocks))
* (100 / SQRT (SQRT (COUNT (blocks))))
FSFI
FROM dba_free_space
GROUP BY tablespace_name
ORDER BY 1;
if the value is very low, we can coalesce the tablespace. But after I coalesce the tablespace, I can't see any space free up.
From <Concepts>:
Quote:Coalescing extents is not necessary in
locally managed tablespaces, because all contiguous free space is available for
allocation to a new extent regardless of whether it was reclaimed from one or more
extents.

We have separate tablespaces for Tables and Indexes. Also Temp is in different temporary tablespace and UNDO also in UNDO tablespace and Index tablespace contains only Indexes. The tablespace usage for tables is 80% and Index is 91%.There is not enough disk space to allocate for the datafile on our system. I ran a rebuild on one of the Index but now notice the Index tablespace is 98% used soon after the rebuild finished.
How can i free up space for Index tablespace and why does the size of Index tablespace increased after the rebuild.
the syntax to make a tablespace's segment space mnagement auto which is segement management is *manual* and exent management is *local autoallocate*.

Since it's 10.2.0.4 database. I have dropped this table by using purge
drop table <<table_name>> purge;
Once table drop was completed. When I check the tablespace space it was 100% free but due to HWM was unable to resize the datafile from current size to small size. What was the reason behind this. Is there any process needs to follow when dropping big tables ? like instead of dropping the tables do I need to truncate first & then drop .

We are in the process of gaining some space in our database. We identified a tablespace that occupied around 400GB of space. The datas are required for us. Hence, we truncated (with drop storage) the tables, gathered statistics and shrinked the tables. After doing that we found the datafile occupied around 32GB of space. We tried to resize it to 5 GB and we got "ORA-03297: file contains used data beyond requested RESIZE value". We could see that size in dba_free_space against that tablespace. We would like to give back everything to OS.
We also tried exporting the tablespace without rows, dropped the tablespace and re-created and imported again. But the datafile grows to around 32G and we are unable to resize it.
We are sure that the tablespace has only the table definitions without data. But we do not know why is it occupying around 32G of space and we could see that size in dba_free_space. We would like to give back everything to OS. How can we do that?

In normal days size of archives generated in a day is 14-15GB. But since yesterday morning, almost 150GB of archives have been generated and are still getting generated(200MB every 1-2 minutes).
There was a sudden reboot of server yesterday morning. At that time there was heavy load of transactions on database. Can it be a reason that smon is still doing recovery? (I am not sure on this). Also, Undo tablespace is increased from 18 GB to 50 GB since yesterday (autoextend on).
Now we are running out of space for archive file system (can't delete them also until they are transferred to DR) Size of redo log is 200MB. This database supports around 2500 users.
performance wise I don't see any hit. Also wait events are normal. (only few db file sequential read) finding the query/session which are causing this much huge amount of archives?
i have a tablespace with a datafile of 20g. now by mistake i delete the datafile and then try to delete the tablespace from EM but i got an error which says that data file is not present to delete
Now initially after deleting the file physically so then i check space by applying df -ah at os lvl so it didn't reclaim the space now i try to delete the tablespace from em so it gives me the above error. This might be due to tablespace existence. so how can i reclaim the space.

It is supposed to take 75 GB. But this table is consuming 135 GB now. It is occupying 8 GB per day.
essentially create data fragmentation within the datafile resulting in the db having lots more space to write into but not actually freeing space, even if you shrink the file it doesnt free space or do a reorg?
We have as an example a DB with 2 billion rows of data in 1 table, no partioning just one large table.
We have worked out that we can probably delete 1 billion rows or even better only keep a rolling 3 month window of data.
What would be the suggestion on deleting this data and reclaiming the disk space to actually see additional disk space made available at the os level.
deleting the data and reclaiming the space.
Through reading it looks like it might be something like, delete, creating new table space partitions from this data. This in theory would create new a tablespace in newly created data files which would result in the data being reorganised and taking up less physical space and when completed you point to the newly created partitions and drop the old tables.
