System tablespace 92% full

Oracle 9.2.0.1
Linux 7.3
I am on a test machine.
The system tablespace is 92%full.Is it an appropriate value?
What should be the size of the system tablespace?
I checked in DBA_USERS,all users have users tablespace ,few system users have system tablespace as there default tablespace.There is a separate temp tablespace for temporary segments.

few system users have system tablespace as there default tablespacei think the OP mentioned users are the one that are created during the creation of database
Once the user has been assigned a tablesapce ..whatever he creates after that by default will be created under the default tablesapce unless it is redirected to use a different tbs provided he has the privilge on that

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 almost full

My database is 10gR2 in Solaris 10. My system tablespace is almost full 99%. What should i do?

This is a UNIX box, right?
/u02/oradata/PPRD/
run:
df -k /u02/oradata/PPRD/
Make sure you have enough space on your disk.
If you have, resize the file:
SQL> alter database datafile '/u02/oradata/PPRD/syst_PPRD_01.dbf' resize xxxxxMB;
It doesn't have to be in AUTOEXTEND.
You don't need to add another datafile, unless you ran out of space on the
disk, then add another database file on another filesystem if you have one.
Modern UNIX file systems still can be expanded, depends on your file system type.
$ chfs -a size=+100000 /u02/oradata/PPRD
Make sure you check all you were asked for.
If you don't have enough dree space, buy another disk.
Regards,
Richard.

System tablespace is 99% full

hello all,
I created a new Oracle 11gR2 11.2.0.3.
i am checking the Oracle Enterprise manager, i saw the my system tablespace size is 700 M and it is 99% full.
Do i have to re size system tablespace datafile?
does that affect my database, do i have to restart it ?
99% full of system table space will affect my database performance?
How can I specify the best size of my system tablespace?
Regards,

That does seem to be the size system tablespace you get with a new db. After a couple of years, mine is still that size, though it appears something has come and gone, but I don't really care.
Recent versions separate out various things into the sysaux tablespace. You do have to watch out that it doesn't start growing. dbconsole has an interesting tablespace map (and there are command lines ways also) to see what segments are in tablespaces. Don't worry too much about any apparent "fragmentation" (and I use that word loosely, and probably shouldn't) you see in the mapping of segments, but it is useful to be aware [url http://docs.oracle.com/cd/B28359_01/server.111/b28310/create004.htm#i1011308]what is in sysaux and why it might start growing. Autoextend is perfectly fine for these tablespaces.
Edit: Auditing is special, and may cause the system tablespace to grow under certain circumstances.

TEMP tablespace getting full while inserting a CLOB in Trigger

We have a Oracle 10g (10.2.0.4.0) DB on a Solaris 9 box which also runs our J2EE web-service application on Weblogic 8sp6 server.
We get around 220K web-service requests from upstream callers daily to insert data in the main table, say TABLE1, which has daily partitions on a date column. This table has around 21 columns out of which 1 is a CLOB column.
Now this table has an AFTER INSERT trigger which calls a package procedure to insert the same record into another table, say TABLE2.
From Java application insert statement in executed in below format using a weblogic jdbc connection pool :
INSERT INTO TABLE1(COLUMN1, COLUMN2, ........., CLOB_COLUMN,........, COLUMN21) VALUES (:1, :2, :3, :4, :5, :6, :7, :8, :9, :10, :11, :12, :13, :14, :15, :16, :17, :18, :19, :20);
Clob object is prepared in application using ojdbc14.jar.
We are observing a strange issue here. The TEMP tablespace utilization keeps on growing as more and more inserts are executed by application and after ~125K inserts the TEMP tablespace gets full and we start getting ORA-01652 error.
On further analysis we could see that there are only 7-10 session being maintained but as more and more inserts happen TEMP tablespace utilization goes on increasing for each of these sessions.
When we tried with inserting just few records and then watching the session details in v$session_wait then we could see that it is in INACTIVE state and waiting for the event ‘SQL*Net message from client’. This does not seem correct as the session has successfully inserted the data and committed the transaction and we can see the data in the tables as well.
The confusing thing here is when we modify the trigger to pass blank string('' ) instead of the CLOB column to TABLE2 then this issue does not occur. All 200K records are inserted properly and TEMP tablespace utilization also keep always below 1%.
Can you please help us in solving this issue. Is this related to any oracle issue?
Inside the package we have tried using DBMS_COPY statement to copy the CLOB column after insert but still same result.
Code for reference:

=====================================

My first thought on reading your post is that not only are you using a database version that is now so old it is in extended support and even then not even the most recent patchset for it.
The first thing I would do is move to 11gR2 and if you can't do that at least get to 10.2.0.5 and apply CLOB relevant patches as well.
Same goes for your operating system. Solaris 9 is ancient: So move to 10 which has vastly improved memory management.
To help you further it would be really valuable to know the table layout. For example is this a heap table or an IOT? Is it partitioned? Is this RAC? What size are the CLOBs? Are they stored in-line? Chunk size? etc.
This page should start you down the right road:
http://docs.oracle.com/cd/B19306_01/appdev.102/b14249/adlob_tables.htm#sthref204
But I am also wondering why you would use a trigger to, as you say, "insert the same record into another table." This description is a poster child for "bad design."

No privileges on system tablespace?

I am a new dba & have succesfully created tables and added constraints.
Today I tried to add a constraint to an existing table, and received the message
ORA-01950: no privileges on tablespace 'SYSTEM'
I tried to add the constraint as the owner of the table, as a user with granted privs on the table, and finally as SYS, and get the same error.
The system tablespace is only about 60% full, and I have not changed any user privs since I last sucessfully added constraints.
If someone would give me a clue as to what's going on, I would really appreciate it.
Thanks, Helen

I granted unlimited tablespace to the user that owns the table, and the constraint was added successfully.
I don't know if a user should have unlimited tablespace on SYSTEM...any advice on what a good limit would be? My system tablespace is 325 M and about 60% full. Would it make sense to grant sys unlimited tablespace on SYSTEM?
Thanks very much for your help. You gave me the incentive to keep trying things until something worked.

Migrating SYSTEM tablespace from DMTS to LMTS in Oracle 9.2.0.7

Migrating SYSTEM tablespace from DMTS to LMTS in Oracle 9.2.0.7 using
brspace -f dbcreate
SAP version: 4.6C
Oracle: 9.2.0.7
OS: AIX 5.3
BRTools: 6.40(42)    /** 6.40(10) or (12) will be sufficient according to SAP ***/
IMPORTANT ***************************************
MUST DO:
1. Create a Full Backup of your system
2. Test your Restore and recovery of your backup.
3. Have a copy of all your tablespaces names on hand
4. Know your SYS and SYSTEM passwords
5. Run CheckDB in DB13 to ensure it is completed successfully with no warnings. This reduce the chance of hitting errors in the process
6. Ensure your UNDO tablespace is big enough
7. OSS 400241 Problems with ops$ or sapr3 connect to Oracle
NOTE: OSS 706625(Read this note)
The migration from a dictionary-managed SYSTEM tablespace to a locally-managed tablespace using the PL/SQL procedure DBMS_SPACE_ADMIN.TABLESPACE_MIGRATE_TO_LOCAL is not supported in the SAP environment.
In UNIX, logon as ora<sid>
run command: brspace -f dbcreate
This command will triggers a Menu. The are seven(7) steps to complete the whole process. Do them in sequence, from step 1 to step 7 faithfully. In Step 1, ensure that your settings of PSAPTEMP, PSAPUNDO etc details such as filenames are correct. The rest I leave it as default and they are fine. Do not change redo log group from 8 to 4 even if you only have 4 redo groups. If not, you might need to restore the system! If the seven steps are complete without errors(warnings is acceptable), congrats. Perform a backup again.
Problems I encountered that caused me to restore system:
1./ Problem: I changed the redo group from 8 to 4 and in the later stage after the tablespaces and files are dropped, the system prompted me that 4 is not acceptable! I can't go back then so a restore is performed.
Solution: Leave the default value 8 as it is
2./ I was using wireless network and the network breaks thus process breaks.
Solution: This process in user-interactive and requires you to input confirmation along the way so do it using LAN.
3./ In the process of dropping tablespace PSAP<SID>, I encountered:
BR0301E SQL error -604 at location BrTspDrop-2
ORA-00601: error occurred at recursive SQL level 1
ORA-01555: snapshot too old: rollback segment number 22 with name '_SYSSMU22$" too small
Solution: I have not fixed this yet but I think it is because my PSAPUNDO is too small(800M) so I will increase it to a bigger value e.g. 5GB
4. Problem: Unable to start sap after successfully migrated. OPS$user problem
Solution: logon as <sid>adm, run R3trans -x in a directory that <sid>adm has read/write permission. R3trans -x will creates a file call trans.log. Read the details and refer to OSS 400241
Result: I have successfully performed this on one(1) system and doing this on the another one currently but encounter Problem 3. Will update this further if there are more findings.

The current one I am implementing is a development system. The database is less than 100GB. 800MB of PSAPUNDO is sufficient for our development usage.
Follow up on Problem 3:
I created another undo tablespace PSAPUNDO2(undodata.dbf) with size of 5GB. I switched undo tablespace to PSAPUNDO2 and placed PSAPUNDO(undo.data1) offline. With PSAPUNDO2 online and PSAPUNDO offline, I started brspace -f dbcreate and encountered the error below at Step 2 Export User tablespace:
BR0301E SQL error -376 at location BrStattabCreate-3
ORA-00376: file 17 cannot be read at this time
ORA-01110: data file 17: '/oracle/DVT/sapdata1/undo_1/undo.data1'
ORA-06512: at 'SYS.DBMS_STATS", line 5317
ORA-06512: at line 1
I aborted the process and verified that SAP is able to run with this settings. I started CheckDB in DB13 and it shows me these messages:
BR0301W SQL error -376 at location brc_dblog_open-5
ORA-00376: file 17 cannot be read at this time
ORA-01110: data file 17: '/oracle/DEV/sapdata1/undo_1/undo.data1'
BR0324W Insertion of database log header failed
I don't understand then. I have already switched the undo tablespace from PSAPUNDO to PSAPUNDO2. Why the message above still appears? Once I put PSAPUNDO online, CheckDB completes successfully without warning.
I did show parameter undo_tablespace and the result is PSAPUNDO2(5GB).
So exactly, what's going on? Can anyone advise?
===============================================
I have managed to clear the message in DB13 after dropping PSAPUNDO tablespace including contents and datafiles. This is mentioned is OSS note 600141 pg 8 as below:
Note: You cannot just set the old rollback-tablespace PSAPROLL to offline instead of deleting it properly. This results in ORA-00376 in connection with ORA-01110 error messages. PSAPROLL must remain ONLINE until it is deleted. (Oracle bug 3635653)

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.
Steps to change SYSTEM tablespaces to locally managed
SQL> shutdown immediate
SQL> startup restrict
SQL> execute DBMS_SPACE_ADMIN.TABLESPACE_MIGRATE_TO_LOCAL ('SYSTEM');
ERROR at line 1:
ORA-10644: SYSTEM tablespace cannot be default temporary tablespace

Problem with purge temp and system tablespace

hi,
i am purging tablespec with sys user and it seems doing it, but tablespaces are still full
also wanted to drop a datafile
alter tablespace system drop
datafile 'C:\oraclexe\files\sys.bf'
and it giving the following error
Error starting at line 28 in command:
alter database datafile 'C:\oraclexe\files\sys.bf' offline drop
Error report:
SQL Error: ORA-01541: system tablespace cannot be brought offline; shut down if necessary
01541. 00000 - "system tablespace cannot be brought offline; shut down if necessary"
*Cause: Tried to bring system tablespace offline
*Action: Shutdown if necessary to do recovery
but if i shutdown how i drop it? or delete manually the file?
sorry for the 2 question in one thread
thanks

but if i shutdown how i drop it? or delete manually the file?Operate in MOUNT state.
But If you need to resize your system tablespace, You have to check HWM.
On XE, I think it's easy to use full exp -> recreate -> full imp..

System tablespace Vs User Tablespace

I'm running oracle 8i at Win2000 Server.
I have a database which have two SYSTEM tablepspaces and One User tablespace. Both SYSTEM Tablepspaces are near to FULL. Right now , The database performance is very poor. I can't understand why my SYSTEM tablespaces are growing fastly instead of User Tablepspace.

You cannot have multiple SYSTEM tablespaces... Do you mean that you have multiple datafiles associated with your SYSTEM tablespace?
Unless you assign users a default tablespace, objects that they create without specifying a tablespace will be placed in the SYSTEM tablespace, which is a bad thing. You probably have user objects in your SYSTEM tablespace.

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.

Tablespace 85% full

Hi,
I see a 'Tablespace 85% full' warning in EM. I looked through the tablespace stats and found it has datafiles that are autoextensible and have a maxbyte number set to 1GB.
Does that mean that the datafiles are autoextensible only till the datafiles reach 1GB?
Thanks.

System tablespace matter

Hi everyone, I had the system tablespace assigned as a temporary tablespace for other users. I changed it, but I think the size of the tablespace grew too much because of this. I know that temporary tablespaces reutilizes space for each user´s session. But permanent tablespaces act in a different way. Right now I have the system tablespace size in 6GB. I want to shrink it. Please, if somebody know how to do it I would appreciate.
Thank you

Are you sure the entire 6 gb isn't being used? If not you should be able to resize it, if it isn't too fragmented. The easiest way is to use DBA Studio or OEM Console. Or in sqlplus
alter database datafile 'full path of your system datafile here' resize 300m;
Substitute the correct size instead of 300m. But, this will only work if the space is free. Also if the file is fragmented (some extents exist beyond the point you want to resize to even though it looks like ample free space) then the only option would be export/import.

System tablespace gets corrupted.

Hi,
My system tablespace gets corrupted. My Database is not running in archivelog mode and also i dont have any backup. Is there is any solution to recover corrupted blocks in system tablespace;

had the same few weeks ago at one of our customers
SYSTEM tablespace (SYSTEM01.DBF) got corrupted due to power outage/disk error
no archiving, no backup (database for testing purposes, which they update periodically with data from the production database)
tried recovery (as Rafi suggested above), but it didnt work, it said SYSTEM01.DBF needs further recovery, thus open resetlogs wont work
and it was right, resetlogs didnt work :)
so the options:
1. recovery/restore - not possible
2. Oracle has a private tool called Oracle Data Unloader that can get the data from the datafiles - just a test database, doesnt worth the work/time/money
3. open the database with the allowresetlogs_corruption=TRUE hidden parameter, and try a full export
database could be opened with resetlogs by using this parameter
the reward for this action: several ORA-600s per second, instance crashed in 30-60 seconds
at the end we dropped the database and duplicated the production one

Shrink system tablespace, or any laternate to reduce disk space usage!

Dear All,
My Database is 11gR1 and Linux is the operating system.
My System tablespace is consuming 24,000 MB disk space, The user i have created that contain all the objects is another tablespace.
I just want to know is there any way to shrink system tablespace or anything else that can be done to reduce its size?
Plus what are the directories from where we can delete logs and other files that do not affect the running of database. My disk space is 99% full and i have to delete files.
Regards, Imran

Regards, ImranFirst, do this:
sql> select distinct owner from dba_segments where tablespace_name = 'SYSTEM';Make sure the only objects in the SYSTEM ts are owned by legit users of that ts - SYS, SYSTEM, and OUTLN
As for log files .. look at your listener log. look at your alert log. look at any trace files in adump, bdump and udump that are old enough you don't want them any more.
