Server Administration :: Any Relation Of Tablespace Disk Space And Actual Data Present In Tables

Aug 16, 2012

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


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 ?

Server Administration :: Single Big Tablespace Versus Multiple Tablespace?

Jan 26, 2011

My database version is

Oracle Database 11g Enterprise Edition Release - 64bit Production
PL/SQL Release - Production
CORE Production
TNS for Linux: Version - Production
NLSRTL Version - Production

My os version is

Linux damdat01 2.6.18-128.7.1.el5 #1 SMP Wed
Aug 19 04:00:49 EDT 2009 x86_64 x86_64 x86_64

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.

Server Administration :: Unable To Use Existing OraInventory Location During Installation?

Jan 5, 2010

i am installing oracle 11g rel2 ( o/s : hp ux 11.31 ). already we have 11g rel1 installed in the machine where oracle inventory location is /oracle/oraInventory where /oracle is ORACLE_BASE directory..

cd /oracle
ls -ltr
drwxrwxr-x 4 ora11gr1 dba 8192 Aug 30 00:19 oraInventory

now when i install oracle 11g rel2 on the same machine, it should use the existing oraInventory..but it is prompting us to enter the new location for oraInventory during installation....but as per the naming convention, we need to keep inventory directory under /oracle/oraInventory only..

when i select oraInventory location as /oracle/oraInventory from wizard, iam getting below error:

[INS-32055] The Central Inventory is located in the Oracle base.

[INS-32035] Unable to create a new central inventory at the specified location.

should i uninstall the exisitng oracle 11g rel1 and then should i install rel2 (i.e what iam trying to install now ) ?if so, after instlaling rel2, then should i install rel1 ?

Backup & Recovery :: Changing Location Of Data And Temp Files From Auto-backup Of Control-file?

Jan 26, 2012

I have an oracle autoback of controlfile and spfile. I am trying to restore the production database using this backup, into a new server with a different directory structure.

I have completed the following steps in the restore process.

1. Creating a pfile from spfile

2. Changing the the location of cdump, udump, bdump and the control files ( there are three )

3. Then creating a spfile from this pfile

I am stuck on the next step where to rename all the datafiles and tempfile and restore the database. Following is what I did.

After mounting the database in RMAN, tried to run the following.

RMAN> run
2> {
3> allocate channel c1 device type disk
4> ;
5> @/home/oracle/rman_scripts/newloc.rman
6> SET NEWNAME FOR DATAFILE 1 TO '/u02/oradata/dorian/system01.dbf';
7> SET NEWNAME FOR DATAFILE 2 TO '/u02/oradata/dorian/undotbs01.dbf';
8> SET NEWNAME FOR DATAFILE 3 TO '/u02/oradata/dorian/sysaux01.dbf';
9> SET NEWNAME FOR DATAFILE 4 TO '/u02/oradata/dorian/users01.dbf';


I am getting the following error message.

System Tablespace - File Contains Used Data Beyond Requested RESIZE Value

Oct 23, 2012

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.

PL/SQL :: Transferring Data From Oracle Table To A File On A Windows Server

Nov 12, 2013

I have an oracle DB version 11.2 running on oracle enterprise linux 5.9. How to transfer data from the oracle DB to a flat file on a windows server. What i have done so far is to use utl_file to create a csv file on the oracle server and am now attempting to transfer this file.

I was going to use scp or rcp but am unable to get this to work(was looking at filezilla). Another option i can use is ftp as i have a UNIX script which i can run to do this. All this is done through an oracle package which is run hourly through dbms_scheduler. I have been using sp_host_command to run unix commands directly from pl/sql so can use this to run a unix script for last resort if i cant find an easier way to automate this.

Server Administration :: How To See Whether Table Data Using Compression

Mar 13, 2013

1)i have 2 SWP TABLES. while dropping a column, i am getting error -
ORA-39726: unsupported add/drop column operation on compressed tables.

2) when i checked compression status, those were not compressed. But as per our code standard, SWP tables should not be in compress mode.

------------------------------ ------------------------------ -------- ------------

------------------------------ ------------------------------ -------- ------------

3) as a workaround, i compressed these 2 SWP tables with OLTP option, and then i was able to drop the column from these 2 SWP tables.

4) Below statement is correct or not ?
IF A TABLE USING BLOCK LEVEL COMPRESSION, THEN this error will come - ORA-39726: unsupported add/drop column operation on compressed tables.

if above statement is correct, then how to find out whether table data is using block level compression ?

5) we have DBMS_COMPRESSION.GET_COMPRESSION_TYPE. using this i just tried to find out, but i am getting "1" as output. I am not getting the exact meaning of it.

confirm what is the conclusion on this ?

SQL> declare
rid rowid;
n number;
select max(rowid) into rid from NOVAR.PAYMENT_SWP;
n := dbms_compression.get_compression_type('NOVAR','PAYMENT_SWP',rid);
2 3 4 5 6 7 8 9 1

PL/SQL procedure successfully completed.

SQL> /

PL/SQL procedure successfully completed.



(ii) 2nd table

SQL> set serveroutput on
SQL> declare

n number;
select max(rowid) into rid from NOVAR.PREPAYMENT_SWP;
n := dbms_compression.get_compression_type('NOVAR','PREPAYMENT_SWP',rid);

Server Administration :: Size Of Data Of Table

Oct 20, 2011

ops$tkyte@DEV8I.WORLD> select blocks, empty_blocks,
2 avg_space, num_freelist_blocks
3 from user_tables
4 where table_name = 'T'
5 /

---------- ------------ ---------- -------------------
19 35 2810 3

Ok, the above shows us:

- we have 55 blocks allocated to the table (still)
- 35 blocks are totally empty (above the HWM)
- 19 blocks contains data (the other block is used by the system)
- we have an average of about 2.8k free on each block used.

Therefore, our table

- consumes 19 blocks of storage in total.
- of which 19 blocks * 8k blocksize - 19 block * 2.8k free = 98k is used for our data.

not too sure this calculation is accurate for getting the size (data)of the table.
