ADD DATAFILE in ASM

Hello
How can I add a datafile in a RAC database with ASM?
The filename are create by ASM are like this
'+DATA/csoprd1a/datafile/aalarge.615.594210853'
where aalarge.615.594210853' is generated by ASM
thanks

Hello Daljit,
I already have this file, and I want to add another one and yes, I'm confused with the numbers, because , they are generated by ASM, so how can I do?
There is an Instance ASM, is there that I must add the datafile?
Regards
Carlos

You can use
ALTER TABLESPACE "SYSTEM" ADD DATAFILE '+DATA1' SIZE 1024M
Cheers

Why asm startwith with + sign? what happen add file in asm tablespace without using + sign,please explain with error no.

Hi folks,
I have one query why asm startwith with + sign? what happen add datafile file in table space,or add disk in disk group without using + sign ,please explain with error no.

hello,
+ sign is to indicate the diskgroup you intended to place datafile. this apply to all database files.
without + sign,will be place in ORACLE_HOME/dbs directory. there will be NO error.
see example here: without using +
SQL> create tablespace test45 datafile 'temdg' size 10m;
Tablespace created.
SQL> select name from v$datafile;
NAME
/u01/app/oracle/product/11.2.0/dbhome_1/dbs/temdg
7 rows selected.
second example: with using + sign to specify diskgroup
SQL> create tablespace test55 datafile '+temdg' size 10m;
Tablespace created.
SQL> select name from v$datafile;
NAME
/u01/app/oracle/product/11.2.0/dbhome_1/dbs/temdg

Alter tablespace add datafile taking too much time

Hi All,
DB Version :10.2.0.1
OS Version: Windows Server 2003 32 Bit
When i am trying to add datafile into tablespace it takes lot of time approx 8 hours.but earlier it take approx 40 to 60 mins
When i check Alert log file i got the message:
ORA-604 signalled during: alter tablespace crbt add datafile
I check there is sufficent space in Disk as i need to add Datafile of 30G.
Syntax i am using is
ALTER TABLESPACE TEST
ADD DATAFILE 'C:\TEST02.DBF' SIZE 30G
Can anyone tell me exactly the reason for the same
Thanks in advance

Hi Aman,
The space is added sometime but most of the time i am getting this error
SQL> ALTER TABLESPACE IN_OCT2011

Add datafile in a network drive

Hi,
I mapped in my NT machine a network disk, but when I try to create a datafile there, the next error message appear.
ALTER TABLESPACE CRM_DATA ADD DATAFILE 'h:\database\crm\dbs\CRM_TAB_5.DBF' SIZE 6000M
ORA-01119: error in creating database file 'h:\database\crm\dbs\CRM_TAB_5.DBF'

O/S-Error: (OS 5) Access is denied.
Somebody know if I need to do something before for Oracle identified this network drive like a other local disk? Can I create datafiles in a network disk?
Thanks.

The architecture of Windows is due to this problem. Keep in mind that YOU do have this share available but the Oracle process has not. You yourself are the connecting user of the share and this share is availbale to you and not to the Oracle process. Oracle itselfs runs in the background (and not on your console) with another user (default Windows internal user: SYSTEM) and you cannot get this share available for this user. The previous reply (run the Oracle service using another DOMAIN user) will help.

Best Practices To Size the Datafile on ASM in Oracle 11gR2

Hi DBAs,
I need to know that what should be the datafile next extent on ASM. I have created a database 11gR2 with ASM. Now some certified DBA told me to create the datafile as small as possible and make it auto extend with the next extent size 1M. The expected data growth every month is about 20-25 Gig.
Please let me know what are the best practices while for sizing the datafiles and extents in 11g using ASM. Any good document/note refer would be great help.
Thanks

Please let me know what are the best practices while for sizing the datafiles and extents in 11g using ASM. Any >good document/note refer would be great help.I don't think there is any kind of recomendations for that, at least, I've never seen. As You probably know, ASM already divides the ASM files (any sort of files written in a ASM diskgroup) in extents and those extents are composed of AU. So, doesn't matter the datafile size, ASM will balace the I/O on all ASM disks in a diskgroup.
I guess this thread ( AU_SIZE and Variable Extent Size ), even not being the subject of Your question, Will help You.
I do believe there are more important factors for ASM performance, like stripe size, LUN size, storage configuration, etc.
Hope it helps,

Error: add datafile to an tablespace

I have a 10g database in Sun machine.
I issued the following command and got this error. What the problem:

Any help will be appraciated!

I believe that is the syntax for add datafile nothing else can be done other than this.
ADD TEMPFILE 'filespec' SIZE int K

Can I add datafile bigger then 2GB

Hi all,
Can I add datafile bigger then 2GB (on the raw device) to the tablespace ?
I get err:
ORA-01119 : error in creating database file '/opt/DISK/data02'
ORA-27042 : not enought space on raw partition to fullfill request
Aditional information : 1
And
partition has size 4096543 kB
when I use partition with size 2GB it is Ok.
Is it limitation by Linux ?
I have linux 7.1
and oracle 8.1.7
What can I do ?
thanks

If you want to use raw devices with linux you have to use the utility 'raw' to map the device. You could also use the Logical Volume Manager (or both)

How to add datafile to standby database

Hi,
We have standby database on another site and we are using manual recovery. How to add datafile to standby database after datafile is added to primary database.
We are on Oracle 9i R2.
Please help.
Thanks in advance

Hi,
When you recover the standby database after you added a datafile to the production, you will get an error that the file that needs recovery does not exist.
At this point you can connect to the standby and issue:
alter database create datafile '<original_name>' as '<new_name>';the new name is optional if the location of the files are the same.
After that, you can continue recovering the standby database.

Add datafile or increase the size?

Hi, I have this question. When is recomendable to add a datafile on the tablespace and when is recomendable to increase the size of the datafile on the tablespace?
Thanks!

What i feel is
if you dont have free space in the file system then adding datafile to another filesystem is the only option.In this case we cannot increase the datafilesize.
NO free space in filesystem---add datafile in another filsystem
else increase data file size.
increasing the datafile increases the time in recovery incase if datafile is crashed.
Datawarehouse Db suits big tablespaxces.
Correct me if i am wrong

Move datafile from asm datafile database to non asm database

Hi Nice morning all DBA Guys, I want move datafile from asm database datafile to non asm configurated database. Hoe to move this?
Datafiles like this
+DATA/saico/datafile/users.259.631612183
+DATA/saico/datafile/DBA.XXX.XXXXXXXXX
Regards
S.Azar

The all files movement of asm to non-asm and vice-versa is given in document id 252219.1 on metalink. Please look at the same. In nut shell you have to do the following:
1. Start your database with ASM.
2. Create pfile from spfile.
3. Edit pfile to reflect controlfile name in file system location.
4. SQL> Startup nomount.
5. Use RMAN to copy the control file from ASM to NON-ASM.
RMAN> RESTORE CONTROLFILE FROM '<filename_of_old_control_file>';
6. SQL> alter database mount;
7. Use RMAN to copy the database from ASM to NON-ASM.
RMAN> BACKUP AS COPY DATABASE format '/u01/oradata/nonasmdb/datafile/%U';
8. From RMAN
RMAN> SWITCH DATABASE TO COPY;

Autoextend user tablespace or add datafile

Hello,
My USERS tablespace had problem today when loading a file using sqlldr. It stopped loading halfway through the file.
The allocated is set to 1900 mb and the used was at 1850. I only have 1 datafile for users tablespace. I have autoextensible to YES.
Why did it not extend the tablespace when I should still have 2gb free??
I dropped a couple unused user tables and it reduced the used amount, then I was able reran the sqlldr load and it completed.
Should I create a new datafile
ALTER TABLESPACE USERS ADD DATAFILE ‘/usr/lib/oracle/xe/oradata/XE/users01.dbf’ SIZE 2000M AUTOEXTEND OFF;
or increase the allocation
ALTER DATABASE DATAFILE ‘/usr/lib/oracle/xe/oradata/XE/users.dbf’ RESIZE 3000M;
Thanks for the help...

Why did it not extend the tablespace when I should still have 2gb free??
Might be maxsize was defined at the time of tablespace creation
For example
SQL> select DBMS_METADATA.GET_DDL('TABLESPACE', 'USERS') from dual;
DBMS_METADATA.GET_DDL('TABLESPACE','USERS')
CREATE TABLESPACE "USERS" DATAFILE
'C:\ORACLE\ORACLEXE\ORADATA\XE\USERS.DBF' SIZE 104857600
AUTOEXTEND ON NEXT 10485760[b] MAXSIZE 5120M
LOGGING ONLINE PERMANENT BLOCKSIZE 8192
EXTENT MANAGEMENT LOCAL AUTOALLOCATE SEGMENT SPACE MANAGEMENT AUTO
Should I create a new datafile
ALTER TABLESPACE USERS ADD DATAFILE
‘/usr/lib/oracle/xe/oradata/XE/users01.dbf’ SIZE
2000M AUTOEXTEND OFF;
or increase the allocation
ALTER DATABASE DATAFILE
‘/usr/lib/oracle/xe/oradata/XE/users.dbf’ RESIZE
3000M; It is good idea to add new file and having multiple file with same size.
Also in future if needed you can relocate datafile to reduce I/O contention.

Can one tablepace have their datafile on ASM also filesystem. ???

Hello Oracle Gurus''
1.can one tablespace have their datafile on ASM as well as filesystem ?? like 1 tablespace =1ASMfile + 1 localfilesystem file
2.also tell me will there be any database error code triggered on the DB alert log file. if we use the datafiles on ASM as well as local filesystem for one tablespace??and any performance issues on that tablespaces which resides on filesystem and ASM disk both? ..if all are fine how the filesystem datafile will be support for ASM rebalancing also mirroring level on ASM ??
3.what is type of SCN? is there any types we have ?
4.what are the wait events views on RAC clusters used? to monitor the cluster events and rectify the issues?

AFAIK no. The files which are present on the disk/file system only and not on asm, are not managed by it so no support for asm based striping and mirroring would be there for them.Second, rebalancing is NOT done for the files but for the disks when they are not present or have become offline due to some reason.
3.what is type of SCN? is there any types we have ?
Just remember one type, System Commit Number and forget about rest.
4.what are the wait events views on RAC clusters used? to monitor the cluster events and rectify the issues?Please see the Performance Tuning section of Oracle RAC Admninistration guide with a special attention to Cluster wait class and wait events related to it. Best is, use EM and it would show all the things in a nice manner.
