Can ASM be used in single node 11g?

I tried to create DB in 11g using ASM, but I was asked to create oracle CSS services (which is for RAC). of course it failed. My platform is oracle linux 5. As I remember 10g can use ASM (in Solaris), any one has idea about 11g? how to use ASM (not RAC)? (I already used ASM in RAC 11g)
Thank you in advance.

Although this is for Oracle 10gR2, here's a web page that might shed some light on your situation: Note that is says CSS is created automatically even if you don't use it.

6.2 Removing Oracle Cluster Synchronization Services (CSS)
The first time you install Oracle Database, Oracle Universal Installer configures and starts a single-node version of the Oracle Cluster Synchronization Services (CSS) service. The CSS service enables synchronization between an Automatic Storage Management (ASM) instance and the database instances that rely on it for database file storage. It is configured and started even if you do not choose Automatic Storage Management as a storage mechanism for database files.
If you do not choose Automatic Storage Management as a storage option, you can delete OracleCSService. To delete this service without deleting the Oracle home, perform the following:

  • Multiple ASM instances on a single node

    Can i have multiple ASM instances on a single node? This is to have each instance supporting different environment dev,stage etc
    Thanks
    Sannidhi

    I had been discussing the same issue with someone from Oracle. I asked for multiple ASMs on a server so that we could have seperate ASMs running for, say, 10g and 11g.
    He explained that we should think of ASM as being the same as Veritas FileSystem. We don't run multiple instances of Veritas on our servers. On single Veritas "instance" (set of drivers) provides all the Veritas Fx mountpoints on the server. Similarly, there should be only 1 ASM instance on a server.
    (substitute UFS or ZFS or CFS for Veritas in the above example and you still have only 1 filesystem manager on a server providing one type of filesystem, although you could have, say , UFS and Veritas co-exist ; just as you could have Veritas, ASM and Raw co-exist on a server).

  • Can I export using a single dump directory to multiple locations in oracle

    I'm trying to do a full database export using expdp utility in oracle 10g. I have a single dump directory that is mapped to a particular file location say /export/dump. I don't want the entire dump file to be stored in the above path. Instead I want the dump to be distributed among multiple files. I know that this can be done using FILESIZE parameter which will distribute the contents to multiple files according to the size we have specified.
    My problems comes here, I want to export my data to multiple locations, the path is different than what I mentioned above, say /first/dump. Now my question is should I create multiple dump directories for each location before exporting or can I omit directory attribute in expdp and specify the complete path in the FILE parameter itself.

    No. EXPDP needs the server component LOGICAL DIRECTORY. If you don't specify the directory, it will go to the default EXPDP path which will be mostly /rdbms/log. It's defined by the parameters DATA_PUMP_DIR.
    You will have to specify directory attribute if you want to point your dumpfile to go to any specific location and you cannot give the directory path in the file name in EXPDP (unlike conventional exp)

  • Can multi users use a single itunes library to update ipods?

    I have multiple users set up on my Powerbook G4 for myself and my 2 kids.
    They just got 4G Nanos for christmas, so I want to share my itunes music with them.
    Can someone please explain how I do this, so that they can log in to their own accounts on the G4, start itunes and update their own ipod nanos individually with music shared from my itunes folder?
    Thanks

    that's actually what i do, i keep my library on an external firewire drive, and then back it up to another external firewire occasionally, as at almost 90gb, i certainly dont want to lose the music i've ripped from my huge cd collection.
    i've also found that while i too was concerned about taking my entire library with me on vacation, i found that i never got too far into my 40gb ipod library, let alone wanting more... i actually use my ipod more, even at work, since i'd rather update ratings and things on there vs the main hd, and i sync manually. maybe just use the ipod for the bulk of what's in the lib, and if there's anything missing that you think you'll want, make sure that is available on the hd when you go.
    if you do go the route of keeping it on the external, i'd go ahead and move it over to there, and then tell itunes that it's in a new place (via prefs), and it might have to re-map a few songs (+/- 10%), but you won't have to do the alias trick, which might not work right if itunes is launched and the ext drive is not mounted. i do the alias trick at home on two computers, and the ext drive at work for the big libraries.
    and while i personally wouldn't recommend it, there are a few apps out there that can "virtually" re-partition the hd, some without having to set it up that way first. i think one is called "drive genius"... i was looking at them about a year ago for my emac, but since it only has a 40gb, i just copied everything over to my ext firewire drive, and then reformatted, tested, and partitioned, and then copied everythign back. it also gave me an opp to do a fresh install of the system, which i like to do every year or so when the time is there for me to do it. it keeps me from cluttering up my computer too much over time, and gets the extra caches and localizations out that onyx and the like don't find.

    ...that document doesnt say you cannot have multiple ASM instances on a node. It says "...ASM, +you only need one ASM+ instance for that computer, to manage the two database instances that use ASM."
    The fact that you only need one - and I cannot think of a good reason to have more than one - does not preclude the fact that you do seem to be able to have multiple ASM instances on a single node, each looking after its own set of disks and diskgroups.
    Again - I cannot think of a good reason to do so though!

  • Multiple ASM Instances on single node

    Hi All,
    After going through some threads it seems to me that multiple ASM instances on a node is not supported and recommended by ORACLE but i coudn't find any ORACLE document or support matrix mentioning this. Can any one give me a pointer to this. Please correct me if i am wrong and Multiple ASM instances are fully supported by ORACLE.
    Thanks,

    Multiple ASM instances on a single node are supported but not recommended due to several issues you could encounter during that kind of configuration.
    Possible interraction between those instances for identification of each disk area usage,each disk area permissions , database instance to asm instance mapping and so on, could result in unwanted behaviour, as ASM is in some way just oracle's representation of LVM.
    Intention is that any kind of distinction/separation of oracle related data under the ASM should be done through the disk groups.
    So it seems it would be better to apply this kind of logic rather than doing suspiciously magical and rare configurations that could bring you similiary strange and unexpected problems.

  • Oracle Single Node RAC - Oralce Clusterware Install

    Hi
    I want to install Oracle Clusterware to perform Active / Passive failiver for a 2 node cluster
    I plan to use Oracle Single Node RAC for this and have Oracle Clusterware control the active passive failover.
    However - I do not want to use ASM in any of my set-up.
    We have a NetApp filer and are using NFS / NetApp technologies to control backups (Oracle snap manager).
    Is this possible?
    All the documents I have include reference to ASM
    If I try and install Grid - I am also asked for ASM information.
    I find ASM an un-necessary overhead given the storage we have and do want to use it,
    Can anyone help?

    Hi,
    no you don't need ASM to have RAC One Node. OCR and Voting disk can be on NFS, simply use Shared Disk location during installation, and you won't get asked about ASM.

    Especially http://docs.oracle.com/cd/E11882_01/install.112/e22489/storage.htm#CDEDAHGB
    What you should use in conjunction with NFS however is dNFS.

  • 2 Node RAC with Single Node Standby Help

    Hello Everyone -
    I'm preparing to set up a 2 node RAC and use a single-node standby database.
    I'm a bit confused on how to set up the Standby Redo Logs on the standby to use the LGWR functionality from the RAC instances.
    Should I just create a set of standby redo logs (alter database add standby logfile...) like on a single-instance environment or do I need to create standby logfile threads (alter database add standby logfile thread. . . ) one for each cooresponding thread on the RAC?
    It just seems odd that 2 RAC redo threads are able to write to one standby redo logfile at the same time (or maybe each RAC redo thread picks the first available standby redo log and writes to it??)
    If anyone has some advice or insight, I'd appreciate it.
    Andy

    Hello Andy,
    Did you get answer to your question about RAC with single standby?
    Could you please share with me your experience if you have done so.

  • Can i use single node manager with two weblogic domain?

    I am very new to weblogic and node manager.
    i had created two domains in weblogic. (single node manger).
    Can i connect both domains with same nodemanger?
    How to do this?

    The node manager uses a nodemanager.domains file to determine which domains it manages, for example,
    domain_name=/path_to_domain/domain_name
    other_domain_name=/path_to_other_domain/other_domain_name
    This file can be found in the NODEMANAGER_HOME, that you specified when starting the node manager (startNodeManager - NODEMGR_HOME="${WL_HOME}/../oracle_common/common/nodemanager")
    When you are running the domain on multiple machines you have to enroll the node manager into the domain (http://docs.oracle.com/cd/E23943_01/web.1111/e13813/reference.htm#i1065827)

  • Cloning a RAC environment using ASM to a single node.

    Hi partners,
    I would like to know if, there is any procedure to clone a RAC environment with Ebusiness Suite using ASM, OMF and raw devices to a single node database?
    I know, it can reached using Rapid Clone, but I would like to know, what are the needed steps to clone the database which is using ASM and raw devices, I am thinking to recrate manually the controlfiles.
    Also, I think that I will need to clone firstable the ASM instance, and then try to clone the database.
    I have looking at Metalink, but I haven't found any Note about that.
    Any advice or help will be really appreciated.
    Thanks in advance.

  • Testing single node ASM on Amazon EC2

    Hi,
    I'm using the 32bit 11g EE AMI on EC2 and have attached 2 5 GB Elastic Block Storage units to /dev/sdf and /dev/sdg. What I would like to do is create an ASM instance using these 2 EBS volumes for testing purposes. Unfortunately on 11g you can't create an ASM instance without starting the cluster services even if it's a single node. When I try to start cluster services as root they always time out and never start. Is there some particular reason that this won't run on EC2? I'm just curious if you've seen anyone do ASM on 2 EBS volumes (even in test mode) and if so, how did they get it working.
    Thanks,

  • Single node file system to 3 node rac and asm migration

    hi,
    we have several utl_file and external table applications running on 10.2 single node veritas file system. and we want to migrate to 3 node RAC ASM environment. what is the best practices in order to succeed this migration during this migration. thanks.

    1. Patch to 10.2.0.3 or 10.2.0.4 if not already there.
    2. Dump Veritas from any future consideration.
    3. Build and validate the new RAC environment and then plug in your data using transportable tablespaces.
    Do not expect the first part of step 3 to work perfectly the first time if you do not have experience building RAC clusters.
    This means have appropriate hardware in place for perfecting your skills.
    Be sure, too, that you are not trying to do this with blade or 1U servers. You need a minimum of 2U servers to be able
    to plug in sufficient hardware to have redundant paths to storage and for cache fusion and public access (a minimum of 6 ports).
    And don't let any network admin try to convince you that they can virtualize the network paths: They can not do so successfully
    for RAC.

  • 12.1.3 EBS single node 11.2.0.3 database to 2 node RAC with ASM

    We are planning to convert single node local/ordinary file system 11.2.0.3 database to 2 node RAC with ASM.
    Please help me in creating the roadmap for the same.
    e.g
    1. Create the shared raw file system
    2. Create diskgroup for ASM
    3.. Convert the local file system to ASM first

  • Install 10gr2 ASM on single node, need clusterware installe first?

    Install 10gr2 ASM on single node, Do I need install clusterware first?
    When I install clusterware on single node, it shows " the specified nodes are not clusterable"
    Thanks.

    ASM and clusterware are two separate things. Clusterware is required only if you are setting up a RAC environment, is this your case? If you are just planning to use ASM then proceed with the RDBMS (database disk) install and use the DBCA to perform ASM configuration. It is assumed you have the raw devices ready to setup the ASM instance. Once the ASM instance is ready you can create the database to use the ASM disks.
