Oracle restart and ASM

Hi,

Hi,
asm resource is depending on diskgroup resource ... if diskgroup res. is not available, crsctl status shows offline, I would expect asm should be also shown as 'offline' (and brought offline) as they are dependent.
What is the point of managing resources via srvctl when it doesn't take care of dependencies? For me it's wrong.ora.asm : is ASM Instance
ora.*.dg : is Diskgroup
ora.*.dg is dependent of ora.asm, not to the contrary.
I can have more than one diskgroup and want only one diskgroup disabled, so I need the ASM Instance (ora.asm) online.
Important:
If you shut down the database with SQL*Plus, Oracle Restart does not interpret this as a database failure and does not attempt to restart the database.
Similarly, if you shut down the Oracle ASM instance with SQL*Plus or ASMCMD, Oracle Restart does not attempt to restart it.
An important difference between starting a component with SRVCTL and starting it with SQL*Plus (or another utility) is the following:
When you start a component with SRVCTL, any components on which this component depends are automatically started first, and in the proper order.
When you start a component with SQL*Plus (or another utility), other components in the dependency chain are not automatically started; you must ensure that any components on which this component depends are started.
Oracle Restart also manages the weak dependency between database instances and the Oracle Net listener (the listener): When a database instance is started, Oracle Restart attempts to start the listener. If the listener startup fails, then the database is still started. If the listener later fails, Oracle Restart does not shut down and restart any database instances.
It makes no sense Oracle Restart to shut down all environment (databases) because the listener down.

  • Oracle RAC and ASM for SAP in SLES

    Hello,
    We are installing our SAP ERP with Oracle RAC 11.2.0.2 on SLES 11 x86_64. According note 527843 (Oracle RAC support in the SAP environment), this is supported for SAP. But as a requirement ASM Cluster File System must be setup.
    But when Oracle Grid is installed, ACFS installation returns the following error:
    ACFS-9459: ADVM/ACFS is not supported on this OS version: 'sles-release-11.1-1.152'
    So Oracle GRID has been installed without ACFS, so we will not be able to use Oracle Clusterware for providing high availability of SAP.
    As this is supposed to be a feasible combination (Oracle RAC 11.2.0.2 with ASM on SLES 11 SP1, Netweaver 7.0), I'm wondering if it is a bug, a lack of documentation or something I'm missing.
    Kind regards,
    Fermí

    Read this below Oracle Note:
    ACFS not supported on certain platforms [ID 1075058.1]
    oracle@node1:~/app/oracle/product/grid/log/node1> tail -1 alertesiha.log
    [client(14083)]CRS-10001:ADVM/ACFS is not supported on SUSE
    Then these can be ignored, since ACFS/ADVM may not be supported for your platform. As of this writing, Sun, AIX, SuSE 10 are all supported in 11.2.0.2 only.  HP-UX, SuSe 11 and RH6.0, as well as Oracle UEK ((2.6.32-100*) are not yet supported in 11.2.0.2. Keep in mind that this does not prevent your Grid Infrastructure stack (Clusterware and ASM) from starting.  This is just an informational message for these platforms
    Extract from SAP Note:
    RAC 11.2.0.2 (x86 & x86_64 only):
    Oracle Clusterware 11.2.0.2 + ASM/ACFS 11.2.0.2 (currently only for SLES10, RHEL5, OL 5.x (without UEK))

  • Oracle database 10g RAC and ASM configuration

    Hi all,
    I want to ask to everybody something about Oracle 10g RAC and ASm configuration. We plan to migrate to Oracle 10g from 9i, and we will begin configuring oracle but we have to decide which configuration are the best.
    Our materials are bellow:
    Hardware: RP 3440 (HP)
    OS : HPUX 11i Ver 1
    Storage: EVA 4000 (eva disk group)
    The problem is:
    Our supplier recommand us to use HP serviguard + HP serviceguard extension for RAC+ RAc and Raw device as configuration.
    But we want to use Oracekl Clusterware + RAC + ASM
    My question is if anybody know what is the best configuration, we want to use ASm.
    Can we use HP serviguard and ASM.
    Some documentations or link explain oracle RAC and ASM configuration will be appreciate.
    Thanks for your help.

    Hello,
    there's no extra RAC software package, but the option is only offered, if one of the supported cluster layers for the respective OS has been installed before.
    10.1.0.3 looks like a complete redesign, but anyway it is a patch, you have to install 10.1.0.2 first.

  • PSU for Oracle Restart 11.2.0.1 AIX 6.1

    Hi Gurus,
    I have applied the patch 9655006 to GI for standalone i,e Oracle Restart.The patch went through fine but changed the owner on the grid directory and permissions.The grid directory under /u01/app/11.2.0/grid should be owned by root, instead after patch its owned by grid now .
    Let me breakdown the steps that i performed for patch aplication.
    1)Unlocked the grid home as root using command "roothas.pl -unlock"
    2)Applied PSU patch as grid user(grid) using command opatch apply .The patch was applied successfully.
    3)tried locking the grid home again using comand "roothas.pl -patch"
    the command failed with the error "u01/app/11.2.0/grid/bin/crsctl[158]: /u01/app/11.2.0/grid/bin/crsctl.bin: cannot execute".
    4)Tried rolling back the patch with command "opatch rollback -id 9655006" failed with error Copy failed from '/u01/app/11.2.0/grid/.patch_storage/9655006_Jul_6_2010_12_27_31/files/bin/oradnssd' to '/u01/app/11.2.0/grid/bin/oradnssd'...
    5)Gave execute privilege recursively in GI-home/ bin directory and the Oracle Restart Stack came up.
    My concerned is how the privileges got changed and how safe/consistent is the environment now after patch?what would be the impact of this on my existing environment?
    ls -ld /u01/app/11.2.0/grid
    drwxr-xr-x 66 grid oinstall 4096 Aug 12 11:24 /u01/app/11.2.0/grid
    Please any inputs would be really appreciated.
    Thanks

    Did you read README of Patch?
    OPatch Automation for GI
    The utility (opatch) must be executed by an operating system (OS) user with root privileges (usually user root), and it must be executed on each node in the cluster.
    Patching the Oracle Restart Home
    Before patching the Oracle Restart home, keep the Oracle Restart stack up and running.
    To patch the Oracle Restart home, as an administrative user (usually root user) execute a command in the following format:
    #opatch auto <UNZIPPED_PATCH_LOCATION> -oh <path to Oracle Restart home>
    So, opatch with root privileges unlock and relock the GRID_HOME automatically.
    This patch must be applied using an administrative user (usually root user).
    My concerned is how the privileges got changed and how safe/consistent is the environment now after patch?what would be the impact of this on my existing environment?Did you take backup of Grid Home before patch?
    Backup of the Oracle home can be taken using any preferred method. You can use any tool such as zip, tar, and cpio to compress the Oracle home. It is highly recommended to take a backup of Oracle home binaries while applying patch set(s) or patches. You should also backup the Central Inventory where the Oracle home is installed, while taking backup of the Oracle Home.
    If you have backup of Oracle Home then you can restore all files of GRID HOME (Oracle Restart) and apply patch using root user.

  • Do we require two listeners. that is ASM listnener and DB listnener in oracle restart

    Hi,
    I have few question's on oracle restart.
    1) Do we require two listeners. that is ASM listnener and DB listnener if yes why and if not what is the reason ?
    2)If we add the components to OHASD,do we have to restart the services ?

    Hi,
    I don't get the point.
    Listener don't hold connection but only redirect it to Instance, is the instance which create a session/process.
    The use of listener is so small it's only for incoming connection, so after  connection is established it is handled by Oracle Database process.
    If you stop listener only incoming connection are affected, all current connection still alive on database.
    1) ASM Connection is done only when someone try to connect at ASM remotely. It's pretty rare the use of it.
    2) Does not matter if you are using ASM or DB Listener,  ff you have a storm of connection incoming on its listener it should be avoided, in setting up the clients in a manner they don't open 100rds of connections at the same time - and with some listener.ora parameters.
    Still see no reason to have two listener.

  • Directory Setup for RAC and Oracle Restart

    I have three database installations that I'd like some insight on the initial directory structure and permissions. The three installations are:
    1) Prod RAC - OEL 5U2, 11.2.0.2 Grid Infrastructure, 11.2.0.2 DB EE with RAC option
    2) Test RAC - OEL 5U2, 11.2.0.2 Grid Infrastructure, 11.2.0.2 DB EE with RAC option
    3) Single Instance - OEL 5U2, 11.2.0.2 Grid Infrastructure Standalone (Oracle Restart), 11.2.0.2 DB EE
    The they all have two users GRID (for Grid Infrastructure Software Owner) and ORACLE (for Oracle Database Software Owner).
    We had a consultant install the databases. It's very weird since we have an inconsistency in directories and permission. I want to understand the inconsistency between RAC installations as well as Oracle Restart Install.
    SEE BELOW: The two RAC servers have different owners for /u01/app/11.2.0.2 directory. The Oracle Restart Installation - Single Instance has the same owner as Prod RAC but different than Test RAC. What the consultant said was that ORACLE_BASE would be /u01/app/oracle for both Grid Infrastructure and Database installations. This was to apply to TEST/PROD RAC (3 node, 3 instances, 1 instance/node) and Oracle Restart installation. The GRID_HOME would be /u01/app/11.2.0.2/grid and ORACLE_HOME would be /u01/app/11.2.0.2/db_1. It seems like the owners aren't setup correctly. Why? I don't want problems with patching or upgrading. If this setup is technically incorrect what is the best way to setup so there's no owner/permission issues. Is it necessary to have two separate ORACLE_BASE's like /u01/app/grid?

    Hello
    I did only check prod, as that is the important one.
    i am afraid that setup is not clean. I won't use the work is wrong, but need to be normalized.
    grid oracle base need to be separate from oracle oracle base, and the grid oracle home, MUST be outside of oracle base/oracle home of the oracle user.
    In a multi user setup, the structure should be as follow.
    grid user, group oinstall, asm* groups
    oracle user, group oinstall, dba and db* groups
    The GRID install, have, grid home and oracle base
    the oracle base for grid should be, /u01/app/grid
    the grid home should be, /u01/app/11.2.0.3/grid
    the Oracle user have several homes, and oracle base
    the oracle base for oracle should be, /u01/oracle
    so, for permissions, when I create this, i do as root
    mkdir -p /u01/app/11.2.0.3/grid
    mkdir -p /u01/app/grid
    mkdir -p /u01/app/oracle
    mkdir -p /u01/app/oraInventory
    chown -R grid:oinstall /u01
    chown -R oracle:oinstall /u01/app/oracle
    then, you install grid .. you have so say oracle home is /u01/app/grid and oracle home is /u01/app/11.2.0.3/grid
    at the end, the root.sh as part of the install will take care of the permissions for oraInventory, and the rest for grid.
    when grid is installed, you can move to the oracle db install you use oracle base as /u01/app/oracle and oracle home as /u01/app/oracle/product/11.2.0.3/dbhome_1
    that will give you

  • Grid Infrastructure installable for Oracle Restart only (No ASM)?

    Hello,
    Can Oracle Grid Infrastructure be installed for its Oracle Restart functionality only? i.e., No ASM,; this box uses local RAID 5 filesystems only.
    This is a standalone 32-bit RHEL 5 system with Oracle Database 10gR2 already installed that I intend to upgrade to 11gR2. Just experimenting with installing Grid Infrastructure for only its restart capability. There isn't anything out there I've found that addresses this other than the Oracle doc stating that the Infrastructure must be installed if I want to use ASM or Oracle Restart.
    I'm currently in the installer in a Software Only installation waiting for my SysAdmin to run the root.sh script, but in looking at this script, it looks like it might try to do things with CRS, voting files and the like, which do not exist.
    Thank you!
    -Jon

    Hi Erik,
    Can Oracle Grid Infrastructure be installed for its Oracle Restart functionality only? Yes ... you can do that installing Software Only
    I'm currently in the installer in a Software Only installation waiting for my SysAdmin to run the root.sh script, but in looking at this script, it looks like it might try to do things with CRS, voting files and the like, which do not exist.Don't worry about that ... at the end of the execution of the root.sh script will report a proceedings to configure only Oracle Restart.
    Only this resource "ora.evmd" will appear online.

  • Solaris 10 and Hitachi LUN mapping with Oracle 10g RAC and ASM?

    Hi all,
    I am working on an Oracle 10g RAC and ASM installation with Sun E6900 servers attached to a Hitachi SAN for shared storage with Sun Solaris 10 as the server OS. We are using Oracle 10g Release 2 (10.2.0.3) RAC clusterware
    for the clustering software and raw devices for shared storage and Veritas VxFs 4.1 filesystem.
    My question is this:
    How do I map the raw devices and LUNs on the Hitachi SAN to Solaris 10 OS and Oracle 10g RAC ASM?
    I am aware that with an Oracle 10g RAC and ASM instance, one needs to configure the ASM instance initialization parameter file to set the asm_diskstring setting to recognize the LUNs that are presented to the host.
    I know that Sun Solaris 10 uses /dev/rdsk/CwTxDySz naming convention at the OS level for disks. However, how would I map this to Oracle 10g ASM settings?
    I cannot find this critical piece of information ANYWHERE!!!!
    Thanks for your help!

    You don't seem to state categorically that you are using Solaris Cluster, so I'll assume it since this is mainly a forum about Solaris Cluster (and IMHO, Solaris Cluster with Clusterware is better than Clusterware on its own).
    Clusterware has to see the same device names from all cluster nodes. This is why Solaris Cluster (SC) is a positive benefit over Clusterware because SC provides an automatically managed, consistent name space. Clusterware on its own forces you to manage either the symbolic links (or worse mknods) to create a consistent namespace!
    So, given the SC consistent namespace you simple add the raw devices into the ASM configuration, i.e. /dev/did/rdsk/dXsY. If you are using Solaris Volume Manager, you would use /dev/md/<setname>/rdsk/dXXX and if you were using CVM/VxVM you would use /dev/vx/rdsk/<dg_name>/<dev_name>.
    Of course, if you genuinely are using Clusterware on its own, then you have somewhat of a management issue! ... time to think about installing SC?

  • Oracle Grid Infrastructure and ASM Tech Supprot

    Is the tech support for ASM covered under the Oracle Database tech support package or I need a separate support package for it?

  • How to Install Oracle Restart

    Hello All,
    I have a standby database with ASM. I would like it to be start on the server reboot.
    I have read chapter 4 of Oracle Database Administration Guide 11g R2 where it mentions
    If you install Oracle Restart by installing the Oracle Grid Infrastructure for a
    standalone server and then create your database, the database is automatically added
    to the Oracle Restart configuration, and is then automatically restarted when required.
    However, if you install Oracle Restart on a host computer on which a database already
    exists, you must manually add the database, the listener, the Oracle Automatic Storage
    Management (Oracle ASM) instance, and possibly other components to the Oracle
    Restart configuration.
    Please can someone help me with the steps to setup Orace restart in 11gr2.
    Thanks

  • Oracle Restart

    I am going to upgrade from 10.2 to 11.2 in linux. I like to add the new feature Oracle restart but i am not going to configure ASM and files hold in file system. If i want to do so how i install Grid Infrastructure seperatly to support only for Oracle restart.

    hi
    The Oracle grid infrastructure for a standalone server is the Oracle software that provides system support for an Oracle database including volume management, file system, and automatic restart capabilities. If you plan to use Oracle Restart or Automatic Storage Management, you must install the grid infrastructure before installing your database.

    Oracle...: 11gR2 (11.2.0.1.0)
    On my test environment, i have a VM running Oracle Clusterware and 2 11g instances. The problem is: The ASM service appears online (through ./crsctl status resource -t, see below), but when a try to connect to the ASM instance as sysasm, it shows me that the instance is idle, and if i try to startup it, the message "ORA-15149: another ASM instance found running on the host" is shown to me.
