Server Administration :: System Tablespace Resize?
Dec 23, 2012
My system tablespace size is 800mb and it sends an alert saying that it has exceeded 80% of its usage.However its total max size is 30gb.
FYI
Its autoextensible is set to 'YES'.
2 Node RAC database.
File system is ASM
My question here is... is it advicable to resize a system tablespace to some size when autoextensible is set to 'YES'
or genrally can we resize a system tablespace when autoextensible is set to 'No' ?
SQL> col FILE_NAME format a40

In my database ,the size of the system tablespace is 1024M.now i found its free space is 477.875M.
SQL> SELECT TABLESPACE_NAME,SUM(BYTES)/1024/1024 M FROM DBA_FREE_SPACE where tablespace_name = 'SYSTEM' GROUP BY TABLESPACE_NAME ; TABLESPACE_NAME M --------------- ------- SYSTEM 477.875
In system tablespace ,the max size segment is IDL_UB1$,it is 167M
SQL> SELECT SEGMENT_NAME, SX || 'M' "Size" FROM (SELECT SEGMENT_NAME,SUM(BYTES)/1024/1024 SX FROM DBA_SEGMENTS WHERE TABLESPACE_NAME = 'SYSTEM' GROUP BY SEGMENT_NAME) WHERE SX > 100 ORDER BY SX DESC; SEGMENT_NAME Size ------------- ----- IDL_UB1$ 167M
The SYSTEM tablespace refuses to autoextend (3 segments in SYSTEM tablespace unable to extend). It sits on its current size of 559MB (auto set to 2GB, increment 10M).
I guess there are no free extends that are that big as 10M.
I want to OFF tablspace AUTOEXTEND on a prodution system, we have many RAC databses and that will be done on all stations. i have got a document from net which was written on 29-Jun-2007 and it says that if need to OFF the AUTOEXTEND of a TABLESPACE so you need to ist make it off on the underlying datafiles of that tablespace so this doc is for Oracle 8.1.7.2.0
I've ran: DROP TABLESPACE x_tbs INCLUDING CONTENTS;
I've read(should have read it prior to action) [URL]tm
and I understand now that I should have stated "AND DATAFILES", However, too late now. the tablespace is removed, but the datafile x_tbs is still present in a folder of my OS.
Is it safe to manually remove it by deleting it from the operating system?
The blocksize for my database is 4096, as i have heard that the minimum size of the datafile is decided by blocksize, but i want to know that how it is calculated as by giving the above syntax the other values will be default. I am trying the syntax in oracle 9.2.0.1.0 version.
I've been ASM quite a while. I've two diskgroups extdg and nordg which are of external and normal redundancy respectively. Total diskgroup size is 9G, usuable space came down to 3mb when i tried to resize it to itz maximum. the value under usable column shows the same.
FYI... i've totally three disks in nordg, two in one failgroup and one in another.The disk sized equally 3g each.
Today i am facing an error when going to rezise the datafile its fixed size is 19000M abut after truncating all tables it is 112M, but when i am going to resize its datafile to 500M its get me an error ora-03297 file contain used data beyond requested size values.
I have done the same before a week without any error.But this time i got the error
I have one generic question about space management. I have one table with size of 1TB. This table stored in ORC1 tablespace. This tablespace contains 70 datafiles.
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 .
I have a "prj_tbl" named tablespace in a user's schema in my database. i have given 100mb size to the "prj_tbl" at the time of its creation and auto extend is open for 10mb,and now this tablespace is using nearly 3.6mb space for its data and remaining space is free,now i want to reduce the size of "prj_tbl" tablespace to 20mb and when i tried to resize it then ,
It throws an error- "'ora-03297 file contains used data beyond requested resize value oracle"
I think this message showing that my new size is small than the size of data on my tablespace but it shows free space nearly 96mb then it means my new size is larger than the size of data on tablespace. How should I reduce the size..
i have a tablespace which contains 121 datafile(max limit reached) as a dba what we have to do?
creating a new tablespace with a datafile and assign the users to the current tablespace which i created now.iif the above process is correct,after some time the tablespace which was filled up got freed up.now can i give the access to the users previous (i.e. freed up tablespace) and current tablespaces

My database is OLP system.
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.

Profile altered. But I get still the warning message every login. ORA-28002: the password will expire within 7 days.

Can I use OFA and Raid system together for Oracle 11g in Windows 2008 Server? I am installing the OS in C drive. Where to install the oracle, location for Oracle_Base, number of logical and physical drive required, size of each etc.
I am planning to use Raid 1 - Controlfile, redolog file and archive log file Raid 1+0 - Datafiles
Also I want to multiplex virtual memory page also.
I mistakenly added a datafile to a tablespace which is asm, however the datafile was created in a default location and not the asm location:
alter tablespace pdaiidata1 add datafile '<filename>' size 2048M;
What I should have done:
alter tablepsace <tablespace_name> add datafile '+DATA1' size 2048M;
Is there any way to move this filesystem datafile into the asm tablespace? In previous Oracle versions, I've taken a tablespace offline, moved a datafile, renamed it, then brought the tablespace back online. Can I do something similar here in this situation?
We had a new outsourcer who completed migration of 1 of our system running under Oracle10g-Solaris 10. We created an inventory script that will list all objects counts of SYS, SYSTEM and ORACLE and all other schemas. This script will be ran before (old server) and after migration (to new server). After migration to the new & bigger server, we noticed from the output of the inventory script for SYS/SYSTEM object counts had been reduced compared from the original/actual value (from the old server). Our outsourcer said that this is not an issue since SYS/SYSTEM objects are not transactional and cannot be controlled.
As we will conform that the migration was completed successfully by our new outsourcer.
we are doing database upgradation 10g2 to 11gr2, while doing pre check before upgrdation ..we have found few duplicate objectes on sys and system schema..
SQL> column object_name format a30 select object_name, object_type from dba_objects where object_name||object_type in (select object_name||object_type from dba_objects where owner = 'SYS')
[code]...
As per metalink note "How to Clean Up Duplicate Objects Owned by SYS and SYSTEM Schema [ID 1030426.6]"..
im going to do drop only below objects ..
DROP TABLE SYS.HELP; DROP INDEX SYS.HELP_TOPIC_SEQ; DROP TABLE SYSTEM.PLAN_TABLE;
and ignore below objects ...
DROP TABLE SYSTEM.AQ$_SCHEDULES; DROP INDEX SYSTEM.AQ$_SCHEDULES_PRIMARY; DROP PACKAGE SYSTEM.DBMS_REPCAT_AUTH; DROP PACKAGE BODY SYSTEM.DBMS_REPCAT_AUTH;
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?
