Asm in oracle 11.1

hi,
I tried to use ASM in oracle 11,red hat 5.
when i create the asm,i got the following errors,but showing the disk while execute listdisks.
It is confusing.Is it correct?
[root@rac1 sysconfig]# oracleasm listdisks
[root@rac1 sysconfig]# oracleasm createdisk -v data1 /dev/sdb1
Disk "DATA1" does not exist or is not instantiated
Writing disk header: done

Pls help

do we still need to take cold backupYou need to take backup. Hot or cold depends on how your DB is running (archivelog or not).

Configure ASM for oracle Grid installation

Hi,
I do not know how to configure ASM for oracle grid infrastructure. As i tried to install oracle grid infrastructure says [INS - 30507] Empty ASM disk group.
I have to configure Asm before installing 11g R2. Please let me know what i have to do and provide the steps to configure and administer asm.
Thanks in advance.

ASM or Oracle instance failure recovery

Hi,
If ASM or Oracle instance crashes because of a disk failure, and the data is safe on other ASM disks, can you re-install Oracle and ASM, and mount the database using the data files on existing ASM disks.
reg,

See https://community.oracle.com/message/12273470#12273470

2- Reasons to separe log & data files are for caching purpuse (i.e. EMC Fast Cache) & recovery.

Regarding ASM in Oracle 11g

Hi
I would like to use ASM storage for my single instance oracle 11gR2 database. I am a little bit confused so that asking some question about Oracle 11g ASM.
1. Does Grid Infrastructure mandatory for installation Oracle 11g ASM instance?
2. Without installation Grid Infrastructure can I full fill my requirements ?

Using ASM in Oracle 10g

Hi all,
I'd like to learn using ASM (Automatic Storage Management) feature in Oracle 10g using a single PC. As far as I know, I need hardware of disk array.
Is it possible to use ASM feature in Oracle 10g in a normal PC? or by using the normal IDE harddisk? or by using external USB hardisk? or by using any software emulator?
I would highly appreciate any guideline.
Thanks in advance.

ASM in oracle 11.2.0.4

Hi,
My PROD system is in oracle 11.1.0.7 and storage is EMC. Now I have planned to upgrade this to 11.2.0.4. My db sze is almost 800GB and keeps growing up to 30-35 GB in a months. Now, my confusion with should i use ASM in upgradation or not??? Some says u should use it ,again some says EMC is good enough to do the tunning part of ASM , so you don't need it.
1. Can you suggest whether ASM is a good choice or not??
2. How to create ASM in standalone server?? Any goof links or steps would be very much appreciable.
Regards,

Hi ,
1. Can you suggest whether ASM is a good choice or not??
===>> Yes ,it is better to use ASM.
+ you can keep all database files in one diskgroup and backup in other diskgroup .
Giving you lesser maintenance.
+ As DBA you have more controls .
+ on ASM ,it will do stripping irrespective of redundancy .
+ if you use normal/high redundancy ,ASM will do ASM level mirroring alongwith stripping.
-- With stripping we get better space utilization.
if disks are coming from different controller ,then load on those disks get shared rather on same disk controller ,making performance better.
2. How to create ASM in standalone server??

ASM and Oracle VM

I am looking for a best practice here for Oracle VM 3.0.3 and to receive the best (Fastest) I/O performance.
We have a FC Storage Appliance with 12 2TB disks in it.
I normally would give this whole thing to ASM as 6 RAID01 2TB Raidsets.
Then Make each RAIDSET an ASMDISK and oracle does the rest as each disk is a member of an external redundancy DISKGROUP.
Now if we through Oracle VM into the mix what is the best practice here to get equivalent performance?
I think I want to do the same with the RAIDSETS, make each one a Repository I guess, and someone make the VM guests aware.
I do WANT to use physical disks and not disk images. I just started playing with the Fiber Channel Appliance today, so I am green when it comes to FC and more familiar with SAS.
Right now the appliance has 6 vdisks and 6 volumes of 2TB each.
I want one VM Guest that can run from 2 different VM servers to have access is the goal. How can I get there?

Present the physical LUNs to your Oracle VM Servers and map them directly into the guests. What are the exact steps to accomplish this? I have the LUNs visible via "fdisk -l" on the OVM server, but that is as far as I have gone. Not sure what to do in the Manager yet, as this is completely different than what I did with NFS disks so far. Where I make the export available to the OVM server, add a new Repository in Hardware/Storage/File Servers/Register File Server. Then once that is created I can present that repository to the VM servers, and then create vdisks. And finally present those vdisks to the guest.
So in this case what are the steps to get to the guest?

Installing Oracle Database with ASM on Oracle VM for SPARC

We're installing Solaris 11 and Oracle VM for SPARC so we can install Oracle Database with ASM. There is a requirement when creating the database that the raw disk have an owner that is the same as the database. Everytime we try to change the owner it will always show that the owner is root.
Any ideas?

Hi
Please let me know from where you are allocating ASM raw disks for the guest domain.
i hope you are changing the disk permissions using chown -R
Also confirm the permission using command # ls -IL /dev/rdsk

ASM in Oracle 10G

Hi
What is ASM how its help for DBA ?

ASM is a kind of file system, created by Oracle, that handles raw disks.
Oracle needs to keep it's data on disk, and that disk is managed by an operating system's file system, by the DBA and SA (raw disk), or by some other tool (ASM).
Since it is difficult (and potentially expensive) getting file systems that support sharing the same disk, as required by RAC, the default is to use raw disk.. raw disk, however, does not have good tools to do things like "list, copy, move and remove files and set permissions, and so on". That is what ASM provides.
Beyond that, ASM also has a bunch of capabilities that provide benefits similar to RAID, but at the file level: disk groups are like logical volumes; file striping is a bit like RAID 0; and redundancy is like mirroring. The differences are - these are optimized for an Oracle environment instead of the 'billions of small files' environments seen by most operating file systems.
This all helps the DBA by
- avoiding the political 'who manages the disks - SAN, SA or DBA' agrument;
- avoiding the political 'which file system' argument;
- giving the DBA information and tools to manage IO.

About ASM and Oracle user

Hi,
is there any way to installing ASM executable and database executable by diffrent operating system user.
It means that
there are two user one of them
[tuba@pttstgen24 ~]$ id
uid=500(tuba) gid=500(dba) groups=500(dba),501(oinstall)
and the other one
[tuba02@pttstgen24 database]$ id
uid=501(tuba02) gid=501(oinstall) groups=500(dba),501(oinstall)
I want to install ASM by using tuba and I want to create db by using tuba02
but it gives the error and db installation did not discover the ASM.
However,
when installing db with tuba on ASM it is successfull?
İs there any way to install ASM and Db by different users??

Hi Terbas,
Its is possible on Oracle 11g, see this link http://www.filibeto.org/sun/lib/nonsun/oracle/11.1.0.6.0/B28359_01/install.111/b28263/rcprelin.htm#BABGCHAD

Standalone server with ASM & database, oracle HAS service not auto start

WE have a standalone oracle and grid on linux redhat 5. Oracle version is 11gr2, and I noticed everytime server reboot, the d.bin processes are all gone and has services are not automatically rebooted during server reboot.
How to handle this issue?
Thanks in advance.

You said:
>
That's not what HAS is for. HAS will restore the services to the state they were if an incident happens that aborts a service. It will not startup your database/ASM when the server reboots. Thats what the famous dbora script is for.
>
Yes it is. Not only will ohasd try to restart failed resources, but it will also (unless disabled) start them in the proper order when the node boots.
I am sorry, but your statement is wrong.
From http://docs.oracle.com/cd/E11882_01/server.112/e25494/restart001.htm#ADMIN12709
>
Oracle Restart improves the availability of your Oracle database. When you install Oracle Restart, various Oracle components can be automatically restarted after a hardware or software failure or whenever your database host computer restarts.

How many control file should be created in ASM for ORACLE 4 nodes RAC

We have a oracle 10G(10.2.0.4) database with 4 nodes locates ASM in redhat linux5.
The vendor created this RAC system with database.
I saw below infornation as
SQL> select name from GV_$CONTROLFILE;
NAME
+FLSDISK1/sale/controlfile/current.256.690290159
+FLSDISK1/sale/controlfile/current.256.690290159
+FLSDISK1/sale/controlfile/current.256.690290159
+FLSDISK1/sale/controlfile/current.256.690290159
It seems that each node with one control file.
I got a feedback that vender claimed SAN is very reliable.
I am new person for database at ASM for RAC.
Could you make a explain for this condition? Do I need to add ( mirror) another 2 control file into ASM?
The Oracle recommands that at least 2 contril files( best 3 files) in different place. This is true for signle instance.
How about RAC that database locates in ASM?
Please help me!!
Jim

You are fine using the standard three controlfiles in ASM, four is fine too, but it does not need to be tied to the number of instances as all the instances in a RAC database use the same controlfile (and its copies). ASM knows the controlfile type and will stripe each one in 128k pieces across as many volumes as it can. I much prefer to have my controlfiles in ASM, it prevents accidental deletion and generally makes DBA life easier.
Cheers!

Stuck in ASM configurartion Oracle 10.2.0 windows

Hi experts,
I recently installed oracle 10.2.0 on win 7... Just software no databaes. Then I tried to configure ASM using DBCA. It showed me error "in order to use ASM the CSS must be configured and started" then I configured CSS by giving localconfig add on cmd..it shows successfully.
But whenever I try to configure ASM using DBCA it again shows the same error.. please tell me the solution.

Pl identify exact version of "10.2.0" and edition of Win 7 - the only supported combination is 10.2.0.5 on Win 7 Professional or higher - Oracle&reg; Database
