How to connect asm instance

hi
I cannot be able to connect to the asm instance.I want to check the space and datafiles inside the asm.

How does 1 ASM instance in a 10 node RAC cause all 10 ASM instance to hang

Linux RHEL4
11.2.0.1.0 GI
11.2.0.1.0 RDBMS
11.1.0.7.0 RDBMS
10.2.0.4.4 RDBMS
Yesterday we had one of the ASM instance on our 10-node cluster hang with a latch "ASM file allocation latch". Oracle support has stated we are hitting a bug with is fixed in the latest PSU.
What I am trying to understand is how a latch on one ASM instance caused all 10 ASM instances to hang?
Oracle Supports explanation still does not answer how all 10 ASM instance were affected other then the faulty code that the patch fixes. Bellow is info out of the SAR.
Data Guard Site:
================
ARC1 PID 21508 reports ORA-240 'control file enqueue held for more than 120 seconds' at Thu Oct 28 11:35:54 2010. This message means ARC1 PID 21508 was holding the enqueue past the maximum tine limit of 120 seconds.
Next ARC0 PID 17398 reports ORA-16146: 'control file enqueue unavailable' at Thu Oct 28 11:36:52 2010. This means ARC0 PID 17398 tried to access the controlfile and it could get the lock.
ARC1 PID 21508 is then killed at Thu Oct 28 11:49:57 2010.
Killing enqueue blocker (pid=21508) on resource CF-00000000-00000000 by (pid=23078) by killing session 5.3
We see that RSM has been restarted by Broker. This matches to the alert.log and messages showing RSM being restarted several time. i.e. RSM0 started with pid=84, OS id=27915
Since this started happening around 11:14, the problem may have really started then instead of w/ the CF enqueue block.
The primary appears to be shipping redo to the standby using asynchronous mode. Unless there was a gap, I do no know if ARC1 should have been doing any remote network I/O. Because a log switch to thread 1 sequence 5235 had just happened at 11:33am, I suspect it was a local disk I/O that was started at least. The ORA-240 is reported at 11:35, exactly 120 sec (or 2min) from this log switch. Notice also the entry to show the log thread 1 sequence 5234 was registered to the controlfile didn't happen yet.
ASM Side:
============
From the systemstate dump on ASM, multiple processes are waiting on 'ASM file allocation latch' and we are kind of stuck on stack:
ksedsts()+461<-ksdxfstk()+32<-ksdxcb()+1782<-sspuser()+112<-0000003218E0C5B0<-kfuhInsert()+175<-kffilCreate()+601<-kfnsUFG()+3691<-kfnsBackground()+4382<-kfnDispatch()+527<-opiodr()+1149<-ttcpip()+1251<-opitsk()+1633<-opiino()+958<-opiodr()+1149<-opidrv()+570<-sou2o()+103<-opimai_real()+133<-ssthrdmain()+214<-main()+201<-__libc_start_main()+219
This caused the hang on the ASM side and hence ASM was not responding to the database. The CF Enqueue issue on the database was a side effect of this.
This is a direct <BUG:9232266> which is a duplicate of <BUG:8974548>

Thanks Murali,
I was little reluctent to open a tar since my experince says that its better to troubleshoot the issue yourself instead of spending time with the Oracle support :)
Well, I got some more information on this : the sql for the process id of ASM instance is :
Alter Diskgroup mount all;
It looks like it is unable to mount the diskgroup and get hunged at that point , is it due to the new disk added to the system or do we missed something after adding the new disk.
Also, the ASM process can not be killed from unix box while the ASM is down.
Will appreciate your time if we can move in any directions from here ..
Thanks ,

How to start ASM instance at boot time - RHEL 2.1

Oracle 10.1.0.3
RHEL 2.1
I'm not able to get the ASM instance (not RAC) to start at boot time. It seems that the ocssd daemon does not finish starting until after all rc* scripts, including rc.local, have finished executing.
Patch 3458327 includes a new dbstart with header notes that are in conflict. The notes says that dbstart can't be used to start ASM until AFTER all rc* is finished. Then it continues and states that ASM instance startup should be put in rc.local.
As soon as I get logged on, a ps -ef|grep ocssd shows the daemon running. I can then manually start the ASM instance. There must be a way to get the ASM instance "auto" started at boot time.
Ideas?

The cheapest and administratively easiest way for me was to start Oracle instances (ASM and data) by "at" command :-) from rc scripts. Something like:
....echo "oracle start" | at now+2min....
Additionally the deferred startup has some additional advantages in my environment, so I am not motivated to look for better solution.
Best regards,
Pavel

How to connect application instance to new DB2 database instance

Hi,
Recently we want to transfer the DB2 database instance from old host( db 9.1.7 under windows 2003 r2) to new host( db2 9.7.9 under windows 2008 r2).
Currently system is:
* ECC 6.0 under NW 7.0 SR3
* DB2 9.1.7 running on windows 2003 r2 64bit.
* Kernel : 7.20
*application instance connecting db instance via DB2 CLI
Refer to below steps when doing the migration:
1) backup the db2 9.1 database using offline methods in source system
2) Using the system copy db depending method to restore the db in target system.
3)Running the db6_update_db script on target system for post-upgrade activity.
4) Running the db6_update_client script on source system to update the cli version.
5) Update the parameter SAPDBHOST to new host in default profile in source host(application).
When i try to restarting the sap system services , it still connected to old host.
May i know any other setting i need to do and then this application server can connect to new db instance.
thanks.

How to install ASM on 11gR2 on Windows?

hi *
can you suggest me how to install ASM instance with 11g R2 software ?
I don't need grid software as a whole.
My goal is to set standalone DB based on ASM storage.
In database server software (DBCA) I cannot choose "create ASM instance" . It's not there.
So I suppose I need to install some of grid software. But which part of it is sufficient that allows to configure ASM afterwards??
there are options:
- Installing and Configuring the Grid Infrastructure for a Standalone Server
- Installing and Configuring the Grid Infrastructure for a Cluster
- Upgrade Grid Infrastructure
- Install Grid Infrastructure Only

- Install Grid Infrastructure OnlyFrom 11.2 onwards, ASM installation needs as a mandatory thing Grid Infrastructure. So if you want ASM,there can't be any thing else which you cna do except installing the Grid Infrastructure. The ASM maintenance has been removed from DBCA and is given now inthe ASMCA(ASM Configuration Assistant) which can only be run from Gird Infra home. So in short, the answer for your question is that you must install Grid Infrastructure if you want ASM , be it Windows or whatever o/s.

FerOracle can not find pfile/spfile for ASM instance to starting.How you created ASM instance? manually or using DBCA?
You actually configured or nor configured ASM instance?.Can you post there parameter file of this ASM instance?
if you have extact name/path of pfile of ASM instance then
export ORACLE_SID=+ASM

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,

How to modify Oracle ASM instance parameters ?
Thank's

I think your response is not correct. The ASM instance will require a parameter file, just like any other Oracle instance. As of 11gR2, the ASM spfile is stored automatically in the first disk group created during the Grid Infrastructure installation.
The trick is that ASM can read the spfile stored on ASM disks through the css cluster daemon and reading the ASM device header. People here in the forum and on the Internet have written good and detailed information about this, for instance:
Where is my Oracle ASM Instance spfile

How to clean the asm instance from RAC manually

for some reason i run crs_unregister asm and crs_unregister lsnr to remove the asm and listener resource from crs yesterday
and today i want rebuild the asm instance ,so i run dbca again ,but error

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
* Select Advanced Installation
