System tablespace issue

Sir,
The system datafile is growing
my USERS DF size is of 30G then the SYSTEM DF size is of 25G
why is it so?
I have checked whether any other user user is using system tbs as default tbs
But that is not the case
then what could be the problem?
thanks and regards

Use the DBA_SEGMENTS view to identify the objects and owners that are occupying significant space. Only after you've identified these can you work out a resolution or action plan.
select owner, segment_type, segment_name, Size_MB
from
(select owner, segment_type, segment_name, bytes/1048576 Size_MB
from dba_segments
where bytes > 100*1048576
and tablespace_name = 'SYSTEM'
order by 4 desc)
where rownum < 11
order by 4 desc ;Hemant K Chitale

SYSTEM Tablespace issue (10.2.0.1 database)

Hi ,
Oracle database 10.2.0.1 (upgraded from 8.1.7.0 via 8.1.7.4)...successfully upgraded
Now when we open dbcontrol, we are getting alerts regarding the Tablespace.
It shows two critical alert messages as below :-
1) Tablesapace SYSTEM (dictionary managed) is 95.16 % full
2) 1 segment in SYSTEM tablespace is unable to extend.
Now how to deal with this type of issues ?
Can we extend the size of datafile of SYSTEM Tablespace which is dictionary managed ? or can we add another new datafile to system tablespace ? what is appropriate solution ?SYSTEM Tablespace
How to solve the point no. (2) as the TS is dictionary managed ?
With Regards

hi ,
Plz add the datafile to the system tablespace tp increase its size , and the conver the system tablespace from dictionary managed to local.
To Change SYSTEM tablespaces to locally managed follow the below procedures:
Before the SYSTEM tablespace can be migrated to locally managed format, you should ensure the following:
The database has a default temporary tablespace which is not SYSTEM
There are not any rollback segments in dictionary managed tablespaces
There is at least one online rollback segment in a locally managed tablespace, or an undo tablespace (if using automatic undo management mode) should be online.
All tablespaces other than the tablespace containing the undo space (undo tablespace or the tablespace containing the rollback segment) and the default temporary tablespace are in read-only mode.
There is a complete backup of the system.
The system is in restricted mode.
Notr, that we already have an UNDO Tablespace. The following query determines whether the SYSTEM tablespace is locally managed:
SQL> SELECT ts# FROM ts$ WHERE ts# = 0 AND bitmapped <> 0;
If 0 rows are returned, then the SYSTEM tablespace is dictionary managed. Otherwise, the SYSTEM tablespace is locally managed.

SYSTEM tablespace extend issue

Hello, I am migrating from 8.1.7 to 9i and I got following error:
ORA-1652: unable to extend temp segment by 3200 in tablespace SYSTEM
As part of migration I added a new data file to system with 100 MB. So in total I have 250 MB of SYSTEM tablespace. Can someone tell mw what I can do?
thanks
Suresh

I have 6 other dBs in 9i and I want to bring all dBs to same level before moving to 10g. Plan is to upgrate to 10g by end of this year.
Can I just add more space and restart the migration or do I need to restore a backup copy and then start the migration?
thanks
Suresh

RMAN duplicate target database for standby from active fails to create newname for system tablespace/datafile

When executing 'duplicate target database for standby from active' the system tablespace/datafile (datafile 1) is not cloned. All other datafiles clone successfully. The RMAN process aborts with the following errors while attempting to clone the system tablespace/datafile.
ORA-19558: error de-allocating device
ORA-19557: device error, device type: DISK, device name:
ORA-17627: ORA-01041: internal error. hostdef extension doesn't exist
ORA-17627: ORA-01041: internal error. hostdef extension doesn't exist
ORA-03135: connection lost contact
Here are the details:
Primary is 11.2.0.2 RAC database on an Exadata platform
Standby is 11.2.0.2 Single Instance database (same patch level as primary) on a Red Hat Linux box
This is an ASM to ASM duplication.
This is not unique to this database. We tried another database and go the same behavior - all datafiles clone successfully with the exception of the system tablespace/datafile.
We have traced the RMAN execution and it seems to fail when it is trying to assign a NEWNAME to the system tablespace/datafile.
We even issued an explicit SET NEWNAME command but RMAN ignored it.
We also shutdown the primary and started is up in mount mode thinking that something had ahold of the System Tablespace/datafile.
We also opened up the network firewall to allow permit any,any traffic.
We increased the max_server_processes
and added TCP.NODELAY=yes to the sqlnet.ora file.
There seems to be some artifact present in our Primary System tablespace/data file that is preventing it form being cloned.
checked all alert files grid, asm, and dbhome - no abnormal messages.
We are in the process of restoring the database from a backup but we would prefer to get this working using the 'Active Database' methodology

I successfully created the standby database using RMAN backup and recovery.
I started the managed recovery. Archive logs are being sent from the primary to the standby ( I can see them in ASM), but the standby is not applying them.
I get the following messages in the standby alert log...

SYSTEM tablespace is growing fast in 10g

Hi,
Using 10.2.0.1.0 on Linux
My SYSTEM tablespace is growing much faster on 10g than it was on 9i, in 2 month it went from 350mb to 500mb, I don't to add more disk, incase there are issues with my database, I want to know why it is growing.
I have read docs on why SYSAUX grows on 10g but not SYSTEM.
SYSTEM size - 500 mb
Schema/size on System are:
SYS______455.8125 mb
SYSTEM______15.25 mb
OUTLN______0.5 mb
In this database I only have 1 very large schema that is 200 GB
Any ideas, reasons, shall I increase it 700mb?
In 9i my SYSTEM tablespace was very static.
Thanks for any help.

Are you using Oracle's audit feature, either standard or FGA? If you were using standard auditing before moving to 10g check that the purge task is still running successfully.
Verify that no users have their temp tablespace set to system. If is still possible for this to happen on 10g.

System tablespace file suffered media failure

Hi All,
Our DB is shutdown due to this error:

Yes Aman.. This happened after cloning in apps.
However, issue got resolved.
Data files were zipped using tar- cvzf ...
I could successfully complete the cloning when backup is taken with "tar cvf" (with out including z)
So, learnt that datafiles should not be zipped when tar.
But datafiles can be zipped using gzip after " tar cvf " is completed.
Am i right ?

System Tablespace objects after upgrade (mdsys, outln, ctxsys, etc)

I have objects in my system tablespace under listed owners. I believe by default with a new 10g install their home is SYSAUX. Is that correct? Oracle changes the default, but doesn't bother to move the objects during upgrade??!!?!!?!!!

Issue was I didn't know what shoudl be in the SYSTEM tablespace and what shoudl be in the SYSAUX tablespace. And what the default tablespace shoudl be for all these id's. I know I didn't communicate that, but I don't think I realized the full extent of the issue until I did further research, which, undfortunately I did after posting the message.
What I found is;
SYS, some SYSTEM and OUTLN objecst can reside in the SYSTEM tablespace
all others shoudl now be in SYSAUX and SYSAUX shoud be the default tablepsace for them.
SYS and OUTLN use SYSTEM as thier default tablespace, however, I haven't definitively identified the default tablespace for SYSTEM db userid.
Facilities owned by the SYSTEM db userid seem to have been diminished in stature, or maybe just determined to be detrimental to SYSTEM tablespace. I have seen notes in during the upgrae process from 8i to 10g that SYSTEM userid should not use SYSTEM as its default tablespace, but exactly what should be used is not clearly defined.
I support Financials E-BS, and we have migrated from 10.7 on 7.x to 11.5.10.2 on 10g. I am afraid that between patching and addressing user expectations, I have not caught all the nuances and adjustments that have coincided with the database upgrades. We have reached a relative level of stability (OCT and JAN CPU's still need to be applied), so I am looking at performance, database standards (through OEM), and tuning.
Thanks for your response.

SYSTEM tablespace full

Hi,
I am new to Oracle database. Currently I am using Oracle 10g version 10.2.0.4. I noticed that the SYSTEM tablespace is 100%, may I know what's the impact to the database server? Will it slow down all the transactions to process?
Thanks.

Your car won't run fast or slow if your gas tank is completely full or half full! The tablespace being full or not completely full won't decide the performance of the database. Since the tablespace is System tablespace which is supposed to store the data dictionary, it being full may hinder the working of the database since there is no more space left the dictionary. But if you would purely do queries without doing any changes at all, those queries performance won't be determined from the tablespace, whichever it may be, being full or not being full.
That said, this is a rather wrong criteria to check the performance. If you want to check performance, first take a feedback from the users and than get a report using Statspack or AWR( if you have license for it) and see what does the report says. If you find anything wrong in it than only imagine it as an issue and try to fix it.

System tablespace is fragmented in 11gr2

ORA-03206 when attempting to AUTOEXTEND system tablespace

Hello.
We're running 11.2.0.2.0 on 64-bit Linux.
A week or so ago, I noticed my SYSTEM tablespace was getting close to it's limit of 32G, so I set it to autoextend by 1G, with a max size of UNLIMITED.
This seemed to work. However, EOM shows it as still having a limit of 32G. I'm guessing the limit of 32G is treated as UNLIMITED.
So, I tried extending to 50G. This failed with ORA-03206. Presumably as the SYSTEM tablespace isn't a BIGFILE tablespace.
The majority of suggestions mention reducing the datafile maxsize, which isn't an option for us.
As far as I can see I'll have to either:
1. Add a new datafile (can we do this on SYSTEM?)
2. Change SYSTEM to a BIGFILE tablespace
Can anyone advise on the best course of action here? I'm guessing 1) is safer than 2) and 2) would need downtime, but would also be future proof.
Any help.suggestions would be much apprciated, as always,
Thanks,
Ray

Many thanks for the quick reply. I also had an inkling that the tablespace was growing unusually fast...turns out it was the FGA_LOG$ table, which lives in the SYSTEM tablespace, which had grown to a massive 25GB!
Another thread deals with a similar issue:
Extents Issue
Truncated FGA_LOG$ and all's well again. We need to examine our FGA policy but for now the problem is solved.

Resizing System Tablespace

Dear All,
My system datafile size has reached around 3.29 GB. I have separated the datafiles and now My query indicates that i am only using 9 percent of the total system tablespace. I need to reduce the size of this file to 400M. i issued the command "ALTER DATABASE DATAFILE '............' RESIZE 400M". i recieve an error saying "file contains used data beyoung requested resize size".
Any comments are highly appreciateable.
Thanks and Best Regards.
Shahzada Khurram Khan

First, no matter which tablespace is the target you cannot shrink the allocated file space to less than the last allocated object.
So map the tablespace: list objects by file, block to see how much room exists, if any, at the end of each allocated file. Then attempt to shrink each file down.
This will take the space away before some other object gets allocated to it.
Next verify that all objects in the system tablespace are only those objects placed there by Oracle when the database is created. Move non-SYS/SYSTEM owned objects to a different tablespace. Repeat above.
The odds are you will still not get back that much of the allocated space. In which case your choices are to either live with it, or to bebuild the database from scratch so that you re-create the system tablespace.

The space used by the schema on system tablespace is not coming back.

Hi user509593!
Adding objects to a tablespace requires space in that tablespace. This space is managed in segments and extents. If an extent is fully used (that means 100 % usage) a new extent will be added to a segment. Oracle uses a mechanism called "High Water Mark" to mark the last used extent.
Your problem is that oracle don't set this High Water Mark back if you are dropping objects from a tablespace. Once an extent is marked as it it retains marked as used.
Before Adding Objects:
u = used Extent
x = free Extent
| = High Water Mark
uuuuuuxxxxx
...........|
After Adding Objects:
uuuuuuuxxxx
............|
After dropping objects:
uuuuuuuxxxx
............|
The only chance to get your "unused" space back is to reorganized your tablespace. But before you reorganize something please read the documentation to know all about the costs and traps that comes with reorganization.
Hope this help!
