On one of our systems, the system tablespace ist growing up fast. The largest objects are:
SYS.C_OBJ# 3 GB (CLuster)
SYS.I_COL1 2,8 GB (INDEX)
SYS.I_COL2 1 GB (INDEX)
SYS.I_COL3 980 MB (INDEX)
why theses objects are going so big? Is it possible to shrink these objects? Table of the three index ist sys.col$ and part of CLuster sys.c_obj#
In our production database server Index tablespace is not growing now... On average index tablespace increases 200 MB to 250 MB per day. Last two weeks index tablespace does not increase..
I am giving you all a statistics of our production db Tablespace usage..

Today I see my system tablespace is 98%, 480 MB used. Why the system tablespace is so big?

Datafile name is +DISK_GROUP_1/oratst1/datafile/system.1122.764387443
displayed for the SYSTEM tablespace in dba_data_files.Infact, datafile name starts with +DISK_GROUP_1 for tablesspaces. Where is the reference to +DISK_GROUP_1.
What file name should I use to resize or to add new datafile to a tablespace?
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' ?

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.
how to reduce the system tablespace size
my system01.dbf size is 6gb
i want reduce from 6gb to 2gb
I'm trying to increase the size of my system tablespace. The tablespace contains one datafile size 900MB and it can increase to 2GB.
I'd like to change this to autoextend as I'm going to run csscan on the database.
When I do change the autoextend and unlimited part of the file I get: ORA-03297: file contains used data beyond requested RESIZE value
I've also tried to increase the datafile to 4GB but still the same. I can see that there is more then enough space on the filesystem.
Oracle Enterprise edt 10.2.0.5
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
View 2 Replies View RelatedI want to remove a tablespace with it's datafile.
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?
what is the Minimum datafile size required for creating a non-system tablespace?
I am trying to create a tablespace by giving the syntax like,
SQL> create tablespace t1
2 datafile '/home/data/t1.dbf' size 72k;
create tablespace t1
*
ERROR at line 1:
ORA-03214: File Size specified is smaller than minimum required
SQL> create tablespace t1
2 datafile '/home/data/t1.dbf' size 73k;
Tablespace created.
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.
Provided a sample table to determine the sales agents performance below.
Id AgenName Zone1 Zone2 Zone3 Zone4
1 ABC 90 85 65 55
2 SDD 45 67 78 90
3 ERF 85 30 52 45
If in any zone, the sales is less than 40, it should be failed.This can be determined using the below query
select Id, AgenName, Case when Zone1 < 40 or Zone2 < 40 or Zone3 < 40 or Zone4 < 40 Then 'Failed'
Else 'Eligible'
End as Flg_Comm
from sales_table;
But the problem is when the zone grows (zone5, zone6) every time the query requires to be added with or condition.
Is there a way to dynamically determine the result even when no. of columns grow (or added)?
We have system.current_item and system.cursor_item.....
both represent the same....
like this we have few other system variables also .....
what is the main difference between current_item and cursor_item?
couple of questions about below parameters, do they measure single processor or avg usage across all processorss and cpus for example will i recieve alert if CPU system time goes above 95% for single processors? or not
CPU Idle Time (%)
CPU System Time (%)
CPU User Time (%)
A streams apply process which applies to a sql sever database is increasing its pga use continually until i stop the process and restart it. I need to stop it once every week or it will use too much of the pga and the database will hand causin paging etc.

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.
My manager has a couple of 2-proc dual-core Opteron servers with 8GB of RAM and RAID controllers. These servers currently run Solaris 8, but he wants to migrate them to a newer Linux systems.

I have a promotion table which is having 3 columns.
PROMOTION_ID

ASSET_VERSION
This ASSET_VERSION
field keep on getting updated by other system where they may update the display name of the promotion_id.The main concept of this table is there will be a unique combitination of asset_id and promotion id.

When I attempt to connect to the DB as SYS, SYSTEM using sqldeveloper I get:

Now I am certain the username and password are correct, I think it has something to do with remote login of SYS account. Are DBA accounts not allowed to connect via network? I get the same error when I try to sqlpython wrapper which I believe uses TCP

As per my req, i need to get the system grants of one user (GRANTEE) using DBMS_OUTPUT API. The requirement get completed using 'SYSTEM_GRANT' as parameter for OPEN function in the metadata api. Please look into part of code which works.
v_meta_handle := DBMS_METADATA.OPEN('SYSTEM_GRANT');
DBMS_METADATA.SET_FILTER(v_meta_handle, 'GRANTEE','SCOTT');
When using above piece, i get sys grants granted to SCOTT user. But i need to use 'DATABASE_EXPORT' as a parameter to my 'OPEN' function.
v_meta_handle := DBMS_METADATA.OPEN('DATABASE_EXPORT');
DBMS_METADATA.SET_FILTER(v_meta_handle, 'INCLUDE_PATH_EXPR','IN''SYSTEM_GRANT''');
DBMS_METADATA.SET_FILTER(v_meta_handle, 'NAME_EXPR','IN''SCOTT''','GRANTEE_EXPR');
The second set filter doesn't work to get SYS GRANTS of one user. It does not throw any error. Simply the filter doesn't work. 'GRANTEE_EXPR' is not a correct value in the 2nd set filter. What parameter need to pass in object_path_expr ('GRANTEE_EXPR')?
In the article regarding gathering CBO Statistics, it states: QUOTE When an Oracle database is created, a job will be scheduled that will generate the database statistics for you. You will still need to collect system statistics however, as these are not collected by the automatic statistics gathering mechanism.
what is the difference between "database statistics" and "system statistics"? In other words, do I need to run this script for each schema owner in my 10g/11g instance?
variable whoami varchar2(20);
begin
select user into :whoami from dual;
end;
exec dbms_stats.gather_schema_stats( -
ownname => :whoami, -
options => 'GATHER AUTO', -
estimate_percent => 15, -
cascade => true).
Lets say you're making upa school database and you awnted to give the students each a unique student number generated by thesystem.
