Create space in ASM Instance

Dear All,
Here is the configuration we have:
Primary Database: Oracle RAC (2 Nodes). 11g R1 RAC, 10g R2 Database using ASM (OS: Windows Server 2003)
Data Guard: 10g R2 Database using ASM (OS: Windows Server 2003)
We are getting the following errors in the alert log file of ASM Instance (Data Guard) - Data Gaurd mode is 'Max Performance':
ORA-00270: error creating archive log +DG_DATAFILES_AND_FB/accelastdby/primary_arch_logs/arc32471_0721252017.002
ORA-19504: failed to create file "+DG_DATAFILES_AND_FB/accelastdby/primary_arch_logs/arc32471_0721252017.002"
ORA-17502: ksfdcre:4 Failed to create file +DG_DATAFILES_AND_FB/accelastdby/primary_arch_logs/arc32471_0721252017.002
ORA-15041: diskgroup space exhausted
Uopn checking the disk group DG_DATAFILES_AND_FB, free space is 0.
What are the possible options to create more space on this disk group? Can we delete some files safely without any impact (for example: Archive logs which have been applied to database)?
Thanks for your advice.
Regards,
Muhammad Riaz

Hi,
First you can add more disks to the diskgroup so you can get more space, ASM will do rebalance once new disks added.
Second, It seems that your archivelog in dataguard were not deleted after being applied. You can delete the applied archivelog in dataguard, use RMAN is the best option
Hope this helps
Cheers

Possible to create new ASM instance and "import" existing diskgroup?

This is my worst nightmare. Two days before a server was about to be shut down, it crashed on me, corrupting the filesystem where Oracle was installed. Setup was an HP-UX 11.11 server running Oracle 10g with ASM storage on a disk array. Both instances were in the filesystem that got corrupted, and amazingly, we don't have a backup, so I'm not able to restore the instance configs and restart the database. Presumably, my data is still sitting there on the disks that belong to the ASM diskgroup, but I don't know how to get at it. I started by creating a new ASM instance, but I can't figure out if there's a way to create a diskgroup out of those 16 disks without wiping out what's on them.
V$ASM_DISK shows all the disks as MEMBERs, with the CREATE_DATE that they were originally created, so I know at least the headers are intact. So is there any way I can manually recreate that diskgroup in my new instance so it will mount the disks and let me at the data?
I realize that not having backups is the height of stupidity, but that boat has sailed. My company also chose not to pay for Oracle Support this year, so I'm kind of on my own. If anybody can at least point me in the right direction or tell me that it's a lost cause, I'd appreciate it.

Well, a little progress. I was able to finally mount the disks in my new ASM instance, and using asmcmd, I can actually see my datafiles sitting there. So now I'm thinking I should try manually creating a new database instance pointing to the spfile that's in there and try starting that. I'm also going to try using RMAN and the XMLDB FTP trick to copy those datafiles somewhere else so I know I can play with them.

ASM instance deletion and converting to RAC

My RAC setup is little complex, i created 2 RAC servers, after that i created 2 new RAC servers, but the shared disk is same, in old RAC i created RAC ASM, which is running fine, in new i make want to create new RAC ASM instance, but when i got to dbca ASM instance page, its seeing all the old ASM Diskgroups. I created ASM single instance , at new 403 box now i want to delete this to convert it to RAC ASM. How i should proceed, So that my old RAC ASM should not be effected,

Hi;
To create ASM instance you should have OS authentication enabled. To connect as user with SYSASM system privilege refer installation guide on how to enable OS athentication for SYSASMDid you check installation guide for this error, it refers to guide.
Also check [this site|http://neworacledba.blogspot.com/2008/05/sysasm-privilege-for-asm.html] and if its not help try [this search|http://www.google.com.tr/search?hl=tr&source=hp&q=how+to+enable+OS+athentication+for+SYSASM&meta=&aq=f&oq=]

Creating a new single instance on a RAC structure

I have a RAC with 2 nodes using ASM, it's perfect running.I don't have any problems with that.
Now I need to create a new instance in one of the RAC the nodes.
So my question is, I need to create a new ASM instance for this new single instance that I will create?
What will be the best practice in this case?

But i will have to create a new ASM instance to control the storage of this new instance?
I have the ASM1(node 1) and ASM2(node 2) I will have to create de +ASM3 on the node 1 to control this new instance?

ASM instance getting down

While production database is operational, ASM instance gets down out of sudden.
The error reflecting in alert log is :
ORA-15064: communication failure with ASM instance
ORA-03113: end-of-file on communication channel
Also in trace files the same error is reflecting. I am unable to find the root cause why the ASM instance getting down again n again .
Kindly help !
Thanks !!

I thought about more input. But well: Check for errors in the clusterware logs next. And check your system logs.
Any tracefiles created by the ASM instance?
A note: You´re on 10.2.0.2.0. Thats way too old. The current version is 10.2.0.4.0. I STRONGLY recommend to upgrade your clusterware and ASM to that version. If you need for some reason you can leave your database on 10.2.0.2.0.

ASM Instance Creation

Hi,
I need to just create a new ASM instance on solaris without RAC,can anyone share docs of what are the pre-reuquiite and the details of creation of ASM Instance.
Regards,
Hussain

The ASM OS prereqs are the same as the DB prereqs - e.g kernel parameters, OS packages.
Really difficult to give advice if you won't say what version of the OS, what version of the database, what storage etc.

Create a new user for oracle 10G ASM instance with sysdba system privilege

Hi,
In our Golden Gate Project, we require the SYS user credential to connect to the Oracle 10g ASM instance to read the database transaction logs.But our client is not providing the SYS user credential to connnect to ASM instance.
I'm getting the error message "ORA-01109: database not open",When I tried to create a new user using the below the steps in oracle 10g ASM instance
1. Login using "sqlplus / as sysdba"
2. Create user <username> identified by <password>;
But in oracle 11g ASM instance, I'm able to create new user by connecting the ASM instance with SYSASM role without issues.
Is there is any workaround to create a new user with sysdba system privilege in oracle 10g ASM instance?.
Thanks in advance .

Hi,
Recreate the password file for the ASM instance as follows:
Unix:
orapwd file=<ORACLE_HOME>/dbs/PWD<SID> password=<sys_password>
Windows:
orapwd file=<ORACLE_HOME>/database/PWD<SID>.ora password=<sys_password>
Now sys password is reset, we are ready to use sys for ASM management. I decided to create another user ASMDBA as I tried above.
SQL> create user ASMDBA identified by test01;
User created.
SQL> grant SYSASM, SYSOPER to ASMDBA;
Grant succeeded.
SQL> select * from v$pwfile_users;
USERNAME SYSDBA SYSOPE SYSASM
SYS TRUE TRUE TRUE
ASMDBA FALSE TRUE TRUE
Please see this link : http://orachat.com/how-to-change-asm-sys-password-creating-sysasm-user-11g/

Yes you are right , I have to make to sure stock budget doesn't get credited.
If you remember in one of my other threads, i wanted to derive commitment item from Matl grp, it was for this purpose. I will derive commitment through matl group at the time of procurement / GR etc and assign a dummy commitment item to stock a/cs. Where as i will derive a consumption commiment item from consumption GLs.

Using DBCA to create ASM instance; no member disks found

OK, we've been struggling with this for two days and we can't seem to find the magic mojo to get it working.
I've got two Redhat 64-bit machines running Oracle 10.2.0.3 on them. Clusterware is installed fine and communicating properly. We've installed ASMLib and created our ASM disks fine and they list correctly using the oracleasm utility.
Our problem is that when I go to create the ASM instance (using DBCA) the member disks do not show up. I have tried changing the "Disk Discovery Path", I've created listeners, started DBCA from different Oracle homes, re-installed, etc... nothing seems to work.
I've even seen a few threads where people have experienced the same problem but have not seen solutions. Anyone have ideas how I can resolve this issue?

Also, I see that you're using block devices while I am using raw devices. I know that
Oracle11 can utilize block devices, especially on RHEL 5, but I am not sure that
Oracle10g can do that.

How to create an asm instance manaually? oracle 11gr2.

env: oracle 11gr2 os: hpux or aix single machine , not rac.
question:how to create an asm instance manaually?? diskgroup,listener,db ,they can be resigistered to crs??
can anyone give me document about it?

Hi,
This is a simple answer:
Automatic Storage Management (ASM)
ASM was a new storage option introduced with Oracle Database 10gR1 that provides the services of a filesystem, logical volume manager, and software RAID in a platform-independent manner. ASM can stripe and mirror your disks, allow disks to be added or removed while the database is under load, and automatically balance I/O to remove "hot spots." It also supports direct and asynchronous I/O and implements the Oracle Data Manager API (simplified I/O system call interface) introduced in Oracle9i.
ASM is not a general-purpose filesystem and can be used only for Oracle data files, redo logs, and control files. Files in ASM can be created and named automatically by the database (by use of the Oracle Managed Files feature) or manually by the DBA. Because the files stored in ASM are not accessible to the operating system, the only way to perform backup and recovery operations on databases that use ASM files is through Recovery Manager (RMAN).
ASM is implemented as a separate Oracle instance that must be up if other databases are to be able to access it. Memory requirements for ASM are light: only 64 MB for most systems.
Installing ASM
On Linux platforms, ASM can use raw devices or devices managed via the ASMLib interface. Oracle recommends ASMLib over raw devices for ease-of-use and performance reasons. ASMLib 2.0 is available for free download from OTN. This section walks through the process of configuring a simple ASM instance by using ASMLib 2.0 and building a database that uses ASM for disk storage.
Determine Which Version of ASMLib You Need
ASMLib 2.0 is delivered as a set of three Linux packages:
* oracleasmlib-2.0 - the ASM libraries
* oracleasm-support-2.0 - utilities needed to administer ASMLib
* oracleasm - a kernel module for the ASM library
Each Linux distribution has its own set of ASMLib 2.0 packages, and within each distribution, each kernel version has a corresponding oracleasm package. The following paragraphs describe how to determine which set of packages you need.
First, determine which kernel you are using by logging in as root and running the following command:
uname -rm
Ex:
# uname -rm
2.6.9-22.ELsmp i686
The example shows that this is a 2.6.9-22 kernel for an SMP (multiprocessor) box using Intel i686 CPUs.
Use this information to find the correct ASMLib packages on OTN:
1. Point your Web browser to http://www.oracle.com/technology/tech/linux/asmlib/index.html
2. Select the link for your version of Linux.
3. Download the oracleasmlib and oracleasm-support packages for your version of Linux
4. Download the oracleasm package corresponding to your kernel. In the example above, the oracleasm-2.6.9-22.ELsmp-2.0.0-1.i686.rpm package was used.
Next, install the packages by executing the following command as root:
rpm -Uvh oracleasm-kernel_version-asmlib_version.cpu_type.rpm \
oracleasmlib-asmlib_version.cpu_type.rpm \
oracleasm-support-asmlib_version.cpu_type.rpm
Ex:
# rpm -Uvh \
> oracleasm-2.6.9-22.ELsmp-2.0.0-1.i686.rpm \
> oracleasmlib-2.0.1-1.i386.rpm \
> oracleasm-support-2.0.1-1.i386.rpm

Configuring ASMLib
Before using ASMLib, you must run a configuration script to prepare the driver. Run the following command as root, and answer the prompts as shown in the example below.
# /etc/init.d/oracleasm configure
Configuring the Oracle ASM library driver.
This will configure the on-boot properties of the Oracle ASM library
driver. The following questions will determine whether the driver is
loaded on boot and what permissions it will have. The current values
will be shown in brackets ('[]'). Hitting <ENTER> without typing an
answer will keep that current value. Ctrl-C will abort.
Default user to own the driver interface []: oracle
Default group to own the driver interface []: dba
Start Oracle ASM library driver on boot (y/n) [n]: y
Fix permissions of Oracle ASM disks on boot (y/n) [y]: y
Writing Oracle ASM library driver configuration: [ OK ]
Creating /dev/oracleasm mount point: [ OK ]
Loading module "oracleasm": [ OK ]
Mounting ASMlib driver filesystem: [ OK ]
Scanning system for ASM disks: [ OK ]
Next you tell the ASM driver which disks you want it to use. Oracle recommends that each disk contain a single partition for the entire disk. See Partitioning the Disks at the beginning of this section for an example of creating disk partitions.
You mark disks for use by ASMLib by running the following command as root:
/etc/init.d/oracleasm createdisk DISK_NAME device_name
Tip: Enter the DISK_NAME in UPPERCASE letters.
Ex:
# /etc/init.d/oracleasm createdisk VOL1 /dev/sdb1
Marking disk "/dev/sdb1" as an ASM disk: [ OK ]
# /etc/init.d/oracleasm createdisk VOL1 /dev/sdc1
Marking disk "/dev/sdc1" as an ASM disk: [ OK ]
# /etc/init.d/oracleasm createdisk VOL1 /dev/sdd1
Marking disk "/dev/sdd1" as an ASM disk: [ OK ]
Verify that ASMLib has marked the disks:
# /etc/init.d/oracleasm listdisks
VOL1
VOL2
VOL3
Create the ASM Instance
ASM runs as a separate Oracle instance which can be created and configured using the Oracle Universal Installer. Now that ASMLib is installed and the disks are marked for use, you can create an ASM instance.
Log in as oracle and start runInstaller:
$ ./runInstaller
1. Select Installation Method

Help while creating ASM instance on rac environment on Linux

Help while creating ASM instance on rac environment on Oracle enterprise Linux 4 x84_64 Update 5 (10g2).
a) Installed ASMLib 2.0 Packages
b) Configured and Loaded the ASMLib 2.0 Packages
c) Created ASM Disks for Oracle
d) I can see, three volumes already defined for ASM file system.
By running following command (on both node), I get following that means disk are detected.
/etc/init.d/oracleasm listdisks
VOL1
VOL2
VOL3
But Disk members not displayed for creating disk groups. I even tried to "Change Disk Discovery Path" button and put "ORCL:VOL*" but still no luck.
Someone told me use, use ADD DISKS button but this button is disabled for me.
Can anyone, please help me if I missing something.

*****SOLVED******
Thanks for reply..
I set the Change Disk Discovery Path" to /dev/oracleasm/disk/* instead of "ORCL:VOL* and this worked for me.

No member Disk displayed while creating Diskgroups for new ASM instance

Have installed CRS
Have installed DB software
Invoked dbca to create asm instance
Instance created
Disk members not displayed for creating disk groups
OS is Hp ux 11.23

The most likely reason on HP/UX is the permissions on the devices, all the devices to be used by ASM (including the devices for alternate paths) should be set to oracle:dba (or what ever user ASM is installed under) and chmod to 664.

Creating ASM instance with dbca

Hi All
I have 3 questions
1 - Is the file needed to install ASM software is the same as the file need to install regular oracle software or they are 2 different installation files ?
2 - Do I need to create 2 oracle homes , one for ASM and one for regular oracle software or only one ORACLE_HOME is needed ?
3 - Do I need to run dbca once or twice to create the asm instance and database instance ?
Thanks

Hello,
1 - Is the file needed to install ASM software is the same as the file need to install regular oracle software or they are 2 different installation files ?
Answer:The regular database uses normal file system but asm uses Raw devices which is not a file system at all it is just an empty disk.
2 - Do I need to create 2 oracle homes , one for ASM and one for regular oracle software or only one ORACLE_HOME is needed ?
actually you will need oracle home and asm home yes in 11g release 2 they added something being called grid infra structure and they made the cluster home and the asm home and the grid home combined in one home but it is not being called oracle home because oracle home is just for the oracle software.
3 - Do I need to run dbca once or twice to create the asm instance and database instance ?
In 10g yes 2 times you will do that and you can run it once and after you install ASM it asks you if you want to do anything else so you can do it once or twice.in 11g release 2 you dont use the dbca anymore to isntall asm you just use the grid software.
Kind regards

Creating ASM instance on windows (manually)

Hi all,
Can anyone guide me steps how to create ASM instance (manually) on windows in Oracle 11g.
Because i am missing local config fine in <ORACLE_HOME>/bin folder in 11g
Regards,
Vikas Kohli

Hi,
From ASM HOME (%ORACLE_HOME%)
# To create a new config
Windows
%ORACLE_HOME%/bin/localconfig.bat add
# To recreate config
Windows
%ORACLE_HOME%/bin/localconfig.bat reset <ORACLE_HOME>Then using DBCA create/reconfigure ASM instance from ASM HOME.
I assume you are using version Oracle 11.1, if it's 11.2 ignore all above.
Hope this helps,
Levi Pereira
