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 RAC and implications for custom developed applications

    Hi,
    I'm wondering if there are limitations to custom developed applications when implementing a RAC solution. I need some advice though I can find no documentation on this topic. Of course the standard database features will work correctly but what about, let's say, OS-specific PL/SQL code? Any advice is welcome.
    Thanks

    Jos,
    What do you mean by OS-specific PL/SQL code?
    The main thing here is you need to make sure it works correctly on all instances, or you must bind it to an instance by submitting it as a job.
    This implies the output needs to end up on a cluster file system, or you need to set up NFS links.
    Please feel free to contact me internally, if you are the Jos Baan I know.

  • Guidelines for SGA and PGA tuning for 10gR2 RAC and ASM ?

    I am looking for tuning information on SGA and PGA tuning for Oracle 10g (10.2) RAC and ASM for a 4TB OLTP and DSS mixed environment on Solaris 10 platform.

    We are running Solaris 10 SPARC 64 bit with Oracle 10gR2 RAC Enterprise Edition and ASM on Sun servers with 32GB of RAM for memory for a 4TB OLTP database.
    It is in design phase so I do not have an existing AWR or Statspack report yet. Is there a best practices guideline on how to size parameters for the SGA (ie: shared_pool_size, etc) and PGA for this environment from Oracle?

    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.

    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.

  • SQLLoader issues of Oracle RAC with ASM

    One of our client wants to use Oracle RAC with ASM for our application, i just want to know if there would be any two-phased commit transactions and SQL*Loader issues in ASM.
    Database is Oracle 10g

    ASM works only at storage layer and has nothing to do with:
    - distributed transactions
    - client executable that connects to database instance: SQL*Loader, SQL*Plus, etc.
    RAC has also nothing to do with distributed transactions: a RAC database is a single database with multiple instances but still a single database; there is no need to use distributed transactions because you have a RAC database.

  • 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?

  • Need to understand basics of Oracle RAC and Grid technology, for training

    I need to understand Oracle RAC and Grid infrastructure, from a manager's / training perspective.
    I see links here and here, so a couple questions:
    - what's the basic difference from a layman's (e.g., a manager's) perspective ?
    - What training options are available for a generic 11g DBA to learn this new technology ? I've seen this course from an Oracle partner ("Course:Oracle 11g: RAC and Grid Infrastructure Administration Accelerated Release 2"), for a boat load of money, for 5 days I think. So we're looking for something a little more reasonable (and accessible), e.g., books, online, etc.

    For a very basic definition, RAC is technology that is used by the database and GI is the infrastructure that makes RAC work. In a forum reply, that's probably all what can be said about both. For a very lengthy answer, you should read the links that you have quoted.
    For #2, the course that you are looking at is called Accelerated as it combines two courses in a single week training-RAC(4) and GI(3). So it's a 7 day curriculum that one would be doing in a 5 day course and that should justify its cost. But let me say, it's a really really good course. But on the other side, it can be quite overwhelming for someone who doesn't know about these technologies already. So I shall suggest that you send your team to each course individually and probably after doing some homework . They can start reading the following books,

  • Cloning 11i non split to split configuration with RAC and ASM

    Hello Hussein,
    I just want to ask some ideas on what is the best way to clone our UAT/DEV environment to our PROD environment.
    Right now no RAC and ASM setup for the source system still 9.2.0.5 but the plan is to convert to ASM + 10g RAC.
    Can you please let me know on what is the best way to setup PROD out of our UAT environment?
    Here's my options:
    1. Install a fresh prod system
    2. Convert source system to ASM + RAC before cloning to target - setup as below:
    (Source)
    APPS server - 32bit
    DB server (2 node RAC + ASM) - 32bit
    (Target)
    APPS server - 32bit
    DB server (2 node RAC + ASM) - 64bit
    3. Clone existing target system (non RAC and non ASM)
    copy source APPL directories to target
    Install 64 bit Oracle 10g to the target system
    clone/convert database source (9i 32bit) to database targer (10g 64 bit) using RMAN.
    Install clusterware 11gR2
    Convert database to RAC
    Can you please let me know on what is the best approach to do this? For fresh install it will take some time to apply the current patch level and applying other patches.
    For Option 2, seems a bit complicated to do 32bit - 64 bit cloning on RAC. Appreciated if you can provide doc id for this.
    For Option 3, not sure how smooth the conversion from 32bit to 64bit.
    Appreciate your insights on this.
    Regards,
    jeffrey

    Hi Jeffrey,
    Since you are on 9.2.0.5, I assume you are running Oracle Apps 11i and not R12.
    1. Install a fresh prod systemThis option requires applying all patches (as you mentioned above) plus you will have to convert to ASM/RAC on the source/target instance. I would not recommend this approach since would require extra work/time.
    2. Convert source system to ASM + RAC before cloning to target - setup as below:
    (Source)
    APPS server - 32bit
    DB server (2 node RAC + ASM) - 32bit
    (Target)
    APPS server - 32bit
    DB server (2 node RAC + ASM) - 64bitWhat are the source and target database version?
    As per (Certified RAC Scenarios for E-Business Suite Cloning [ID 783188.1]) this is supported by Rapid Clone. So, in this case you need to convert the source instance to RAC and migrate to ASM then use Rapid Clone to clone the application/database.
    Cloning Oracle Applications Release 11i with Rapid Clone [ID 230672.1] -- 6. Cloning a RAC System
    You will have to convert the target database then from 32-bit to 64-bit.
    3. Clone existing target system (non RAC and non ASM)
    copy source APPL directories to target
    Install 64 bit Oracle 10g to the target system
    clone/convert database source (9i 32bit) to database targer (10g 64 bit) using RMAN.
    Install clusterware 11gR2
    Convert database to RAC Here you will have to convert to RAC/ASM on both the source/target instances -- You are eliminating the patches part in Option 1, but again extra work need to be done to convert the database from 32-bit to 64-bit on the target instance + convert to RAC and migrate to ASM (on both instances).
    Based on the above, I would recommend and suggest you go with Option 2.
    Thanks,
    Hussein

  • Question about RAC and ASM

    Hi,
    We are thinking about build RAC using ASM for OEM database. It'll have two nodes, oracle 10g and Hitachi san with solaris ( or linux ). I've few questions about RAC and ASM.
    1) Do I need to have ASM instance running on each node ? ( most likely yes... but want to make sure )
    2) can I share oracle_home between ASM instance and database instance ? what is the best choice ?
    3) I'm planning to use shared disks for all files, all databases.... what are the pros/cons ?
    4) what should be the installation procedure ? Meaning, first create ASM instance on each node, then install cluster software, build RAC databases...... can someone explain..
    5) I believe RMAN is the only option for backup since I'm using ASM, correct ?
    I'm a newbie to RAC and ASM..
    Thanks,

    2) can I share oracle_home between ASM instance and database instance ? what is the best choice ?in 10g you can, in 11gr2 you cannot. and it might be better to seperate them because it will give you more flexibility with patching.
    3) I'm planning to use shared disks for all files, all databases.... what are the pros/cons ?if you share your oracle_home you won't be able to do rolling updates. so i recommend to keep oracle_homes local.
    4) what should be the installation procedure ? Meaning, first create ASM instance on each node, then install cluster software, build RAC databases...... can someone explain..follow the install guide for your respective version. for 10g you'd install clusterware first, then asm and database is last.
    5) I believe RMAN is the only option for backup since I'm using ASM, correct ?pretty much. you could stop your database and dump the raw devices or use asmcmd/asmftp but rman is definitely the best choice

    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.

  • RAC and ASM with geographically seperated disks

    We are planning to use RAC and ASM with four nodes. The two nodes will be at one location and another two nodes at different location. The ASM disks also will be available locally. Is it possible to configure ASM with geographycally serepared disks.
    We are thinking of two RAC and ASM setups with two nodes each and streams replication between the RACs.
    I want to know what is the best method to implement. Is it RAC with four nodes OR two RACs with two nodes each and streams replication between the RACs.

    Apart from the latency issue, which has been mentioned by others, you also need to mirror your disks between the two sites and be very careful about split brain scenarios under node or site crashes.
    You need to mirror the disks between the sites in case one site crashes completely and loses all network access. The only way the second site can carry on is if it has access to all the data disks, and the cluster control disks (terms vary for this, such as quorum or voting disk). If you do not mirror you simply do not have a resilient design. Resilience is about eliminating all single points of failures, which means duplicating everything i.e. mirroring.
    And mirroring between two remote sites adds more volume to the data traffic between the two sites. And it would need to be synchronous rather than asynchronous to guarantee no data loss. And your commits for each transaction would be limited by the round trip time to write to the remote site and get the acknowledgement back.
    Split brain is something you need to avoid with remote clusters, and local clusters too. If the network goes down between the two sites and both sites have local copies of all of the data and cluster control disks, which site becomes the primary and which one becomes the standby? You cannot have both sites coming back up as primary with active databases and accepting transactions! At this point you have split brain, and each side is processing transactions independently, and both databases are now deviating from each other with different data changes.
    I don't think a 4 node RAC environment split across geographical distances is really viable, except under small transaction volumes, and where response time (transaction time) is not critical. If you have high volumes and need fast transactions then you need to only use local RAC configurations, and replicate between the two sites asynchronously. DataGuard is easier, but you need to decide if you need Streams and how to make it work for you.
