• RT 8 Windows Server 2008 newbie question

  Hi guys,.

  Just saw a difference between server 08 & 08 RT server is that RT is only 64-bit. Is this to say that the server is accessible only by the 64-bit systems?

  Also, I'll be able to connect to the server with older versions of windows / other operating systems?

  Thank you!

• Installing Oracle RAC: Unix, Windows ASM nodes

  I have a question about the Oracle RAC configuration. I never did no prior installation RAC or ASM. Maybe a stupid question to some of you.
  
  Is it possible to install Oracle RAC with following options?
  
  2 node RAC with Sun Solaris
  Shared storage using ASM in Windows server
  
  Any additional information you can provide will be greatly appreciated.
  
  Thanks in advance

  In very simple terms, when using ASM, database server process read the CRUDE device and process DBWR write devices ROUGH containing tablespace information. With ASM, these processes simply ask ASM 'where the disk read/write. Therefore, ASM provides simply a "table of contents". (It is much more than that, but this seems to be a good way to start the discussion.)

  ASM MUST run on the same computer as the database instance that is to use it.

  In your scenario, the Windows computer may be Server iSCSI providing raw devices to Solaris machines. These devices would then be managed by ASM and reading/praav1s directly by database processes.

• Oracle RAC and replacement of equipment

  Hello world

  next year our Oracle RAC (hardware) servers will be is more supported. We have a 2 node RAC (SE) running on Linux 5. For you, what is the strategy easier (and safer) to replace the equipment:

  • Reinstall complete with database exports / imports.
  • Adding new nodes to the cluster with new servers and delete 'old' (but it seems that the same version of operating system is required in accordance with the documentation).
  • Clone of the cluster according to the Oracle documentation on news servers.

  Thank you for all your ideas. I googled a bit, but I've not found much info.

  Carlos.

  • Adding new nodes to the cluster with new servers and delete 'old' (but it seems that the same version of operating system is required in accordance with the documentation).

  It's what I strive for. If your time with new nodes in the cluster is short (less than 24 hours), and you stay on the same distribution (i.e. OL5 to OL7), then several times, this isn't a problem. If you still have concerns and do not feel comfortable with this recommendation, then I'll recommend another avenue. I often used it when I was doing something similar for the production system was too critical to take no risk.

  1. Up new servers in a cluster. You can even start with the version of grid Infrastructure more later/more big who can save a future update maybe you.
     1. It will take a new OCR and voting disk new configuration.
  2. Attach the storage shared on the new cluster. For a short period of time, you will have storage mounted to both old and new.
  3. Install the RDBMS software on the new cluster. Wear on all the config files you might need more... tnsnames.ora, sqlnet.ora, etc..
  4. When you are ready to drop the database on the old cluster, cutting on the new cluster.
  5. Use "srvctl database add" to add the database to the new cluster.
  6. Use 'srvctl add instance' to add the instances to the new cluster.
  7. (Optional but normally a good idea), use 'srvctl add service' to add services to the new cluster.
     1. Steps 5 and 6 above usually use the same name of db, same instance names, same service name.
  8. You now have the database running on the new hardware. Stop the old servers

  The only other sticking point would be handling the SCAN and traditional VIP. When I made this drive, I usually my network guy change the SCAN VIP and traditional dignitaries to be alias in DNS that point to the new VIP.

  If you do your homework and have everything ready to go, the downtime can be less than 15 minutes for this approach.

  See you soon,.

• Issue of INS-35354 when installing Oracle RAC 12 on infrastructure Oracle Grid 12

  Hello

  I am trying to install Oracle RAC 12.1.0.2 one node installation on Windows Server R2 2012, but the installer told me:

  'Valid [INS-35354] the system on which you try to install Oracle RAC One doesn't not part of a cluster.'

  On the same server I have is installed and running Oracle Grid Infrastructure + ASM.

  I don't know what is missing the installation program, which is possible to register? The installation program does not provide which had not passed the specific audit.

  Thanks for the tips

  Georg

  

  

  

  Hello

  A CCR node does not mean that you install the grid infrastructure in a single node and install a base of a RAC data on this node.

  Basically, a concept CAR is similar to active passive clustering to provide high availability. To have a node database RAC upward and launched, you will have to install clusterware on at least two server by selecting the option during the installation of the IM.

  Pls follow the below post for detailed answer

  Someone at - he encounter the same problem with 12.1.0.2 by deploying the CDB for Grid Infrastructure Management repository? Is there something special with UEK3 (3.8.13 - 35.3.4.el7uek) on 7 OEL? Any necessary special kernel parameter (although the runInstaller controls do not mention)? I'm totally tapped by GI 12.1.0.2.

  I was finally able to solve this problem.

  She was related to a memory on the provisioning of problem in the virtual environment as both nodes are VMs. Unfortunately none of these errors of memory were populated / pushed somehow in the virtual machine.

• Is it possible create Oracle RAC on NFS datastore?

  Hello

  Is it possible create Oracle RAC on NFS datastore?   With the VMFS data store, we use VMDK files as the Oracle RAC shared virtual disks with the Comptrollership and multi-writer SCSI Paravirtual, what about the NFS datastore? is the controller SCSI Paravirtual and writer multi function supported on the NFS datastore?

  Unless I'm missing something, this is not supported on NFS.

• Change password for an Oracle RAC installation account

  All,

  I'm not an Oracle DBA, but currently I am asked to fill in until a certified Oracle DBA lights.  I work with MS SQL Server and have servers managed for some time.

  That being said, my question is probably a simple.  In the Oracle 11 g RAC 2 installation guide, it tells you * must * use an account that exists on both servers to install.  So far, so good, we have a domain dedicated to this purpose and no other account.  However, due to a recent change in policy, we must also change the password on this account on a regular basis (annual).  My question is, which, if it is, a will this affect on our Oracle RAC database facilities?

  If we simply change the password at the domain level, rather than to check the "must change password at next login", is this cause problems with our data?

  My inclination is no, we have no problems, because current services 'running' Oracle use the local NETWORK SERVICE account that will not be changed, but confirmation of this would be appreciated.

  Environment:

  Operating system: Windows Server 2008 R2 SP2

  Oracle: 11.2.0.2 and 10.2.0.4

  GRID: 11.2.0.2

  Thank you

  Jason has.

  Change password of OS isn't a problem for Oracle DB.

• Oracle RAC with MRS 5.1

  Hi, good day to you all...

  Did anyone here ever has implemented or tested Oracle RAC protected with Vmware SRM?

  VMware SRM 5.1 does support Oracle RAC?

  AFAIK, the VMs CARS they shared virtual disk to another RAC VMs. in my VMs RAC Setup - B had 7 virtual disk mapped to RAC - A VMs and everything works very well in a production environment, and they intend to protect this RAC VMs with VMware SRM 5.1. We use replication Array with EMC RecoverPoint as SRA.

  When I try to test failover my protection group which is containing these two VMs, VMS in RAC - B not able to start with the following error

  

  The virtual disk mapping prevented virtual machines to start upward, and there is no snapshot of the CAR - A or B - CARS.

  Can I modify the virtual machine starts action of the stimulus package, im setting of the RAC - B to not power on the recovering site. map manually the virtual disk after the failover of the trial and the RAC - B still cannot start the system.

  Please give me some lights, how to map the virtual disk after failover to the recovering site.

  Thanks before

  Good find!

  CTK files are created by ESX when CBT (changed block Tracking) is enabled. CBT is used by the backup software and is not supported with disks using shared bus.

  So it can certainly cause problems. Do you have a backup solution for virtual machines?

  CBT can be turned off (requires a virtual machine downtime):

• Need to size the Oracle RAC database settings and configurations as storage size % etc.

  Hi Experts,

  We have a requirment that we need size parameters of database to an Oracle database RAC 11g as the sizing of disk space, memory, and CPU (SAN), Cluster size etc what would the size of the recommendation for major banks or large project? Can you describe in sizes (TB). I'm not sure of the growth of the DB files on a daily basis and no customers.

  Thanks in advance.

  It is a bit of an oxymoron.

  You ask for one RAC server sizing. When RAC architecture allows you to evolve by adding more servers.

  So if you have treatment volumeX to do, you have only 2 servers fabricant1 RAC to deal effectively with him. Or you can need 4 servers Fabricant2 CAR care effectively. There are many factors (unique to this client) which determines the choices made.

  So 'sizing' the server is not a matter to be treated, until you've decided just what type of server, you will use for your RAC (dual core, quad core, 8 cores, base 16, etc.), how much he must take care of the memory, the amount of energy, it would consume, it takes up the amount of space (rack units) in a Cabinet how much local diskspace, it must support, how many PCI slots must be to HBA and HCA and other cards, etc.

  Once this is decided (1 rack unit, dual core processors 4, 2 PCI slots, etc), can you evaluate vendors and server models available and decide how much of these servers must be purchased to meet the needs of data processing envisaged.

  If for example, the decision is 3 servers and after deployment, it is determined that server capacity has been underestimated, then a 4th server can be purchased and added to the cluster of 3 Server - and the cluster set scale to actually do deal with the volumes of data processing.

  One of the fundamental reasons for RAC is scalability. This means that only one server sizing is much less important than choosing the correct h/w architecture which allows to evolve this cluster by adding more h/w.

  It would be very stupid to buy and build a server 2 CARS which was 'size' for volumeX, then find that the volume is X + Y, and 2 servers can only be resized at great expense to 3 servers (for example 4 unit rack servers, rack unit space only 2 left in the cabinet, required for quad powersupply by server power cannot be satisfied for 3rd server) (, no fiber port more SAN, etc.).

• How to install Oracle RAC using GR 11, 2 on Win 7 32 bit from scratch?

  HIII,

  I am a cool and I have a win 7 32 bit with oracle 11 g 2 system.

  I want to install RAC with two servers or more, but I don't know too much about.

  I tried searching on google but all they give information into pieces (for win 7) or Linux on (please tell me why its all Linux everywhere not Windows).

  Please let me know if there is a site where I can find installation step by step from scratch.

  What are the basic requirements (/ software if necessary).

  Thank you.

  Hello

  Firstly forget Windows! Oracle is mainly designed for Linux systems. Oracle as a true process runs multiple on the Linux machines while under Windows, it runs as a single process with multi-thread.

  Using memory - huge pages, single CPU run queue, drop-outs, storage... etc are a lot of concepts.

  Also Windows is one of the most poorly designed operating systems, you must use only for watching movies of cute kitten on youtube... Believe me, you don't want to learn Oracle on Windows...

  Install virtualbox and then configure Oracle Enterprise Linux on it at first... By the way you have to deal with the DNS server of version 11.X, RAC, you can start with 10g for now.

  ORACLE-BASE has all the installation steps explained detailly, search for "oracle rac install base" on google.

  I also explained on my blog, but it is a little more advanced installation by using the ZFS storage Simulator. The DNS server installation is also explained: http://ilkertaysi.com/2013/11/11/oracle-rac-installation-with-zfs-storage/

• Oracle RAC - TAF

  Dear all,
  
  I have a knot two Oracle - RAC configuration in place.
  
  OS: Windows Server 2003 EE 64-bit
  Database: Oracle Database 10 g Release 2 Patch - 3 (64-bit)
  
  Instance type: two-node RAC
  
  Node 1: testdb1
  Node 2: testdb2
  
  I use the following tns alias to connect to the database:
  
  TESTDB_RAC =
  (DESCRIPTION = (LOAD_BALANCE = WE)(FAILOVER = ON) (ADDRESS = (PROTOCOL = TCP) (HOST = testdb1-VIP)(PORT = 1521)) (ADDRESS = (PROTOCOL = TCP) (HOST = testdb2-VIP)(PORT = 1521)) (CONNECT_DATA = (SERVICE_NAME = testdb)(SERVER = dedicated) (FAILOVER_MODE = (TYPE = SELECT)(METHOD = PRECONNECT) (ATTEMPTS = 20)(DELAY = 3) (BACKUP = TESTDB2))))
  
  What I want to achieve:
  
  (1) when I start SQL * Plus (or any application using the alias above) and connect to the base, I expect to connect to the two instances (using the PRECEONNECT clause).
  
  (2) shoot node-1
  (3) my database connection must exist yet with the second instance (node-2)
  (4) set up the node-1
  (5) to lower node-2. Now, the connection should failover to node 1.
  
  Rather than fail to node-1, my database connection fell, and I have to reconnect to the database.
  
  We would like to have this transparency when applications to talk to the database. Applications should NOT feel failure of one of the nodes. Interruption of node should be transparent to the application.
  
  Appreciate your comments on this.

  What's doing BACKUP keyword in the FAILOVER clause?

  It specifies a different net service name to use for the connection of relief. A backup must be specified when you use PRECONNECT to establish connections. Specification of a BACKUP is highly recommended for the BASE methods; otherwise, it may first attempt which has just failed, adding an extension until the client reconnects.

  >

  TNS alias on the node-1 should have BACKUP = TESTDB2 while Tns alias on the node-2 should have BACKUP = TESTDB1. Please validate my statement.

  Yes... You are right...

• Then Toshiba send me a new windows disk?

  I brought my laptop for Christmas, he came with a windows disk (they can be on at the bottom of the box, I'll check when I get home) but came pre-loaded with Windows Vista.
  I have a few XP discs but I don't want to go back to XP now.
  So, if I don't have a disc, is it possible to send off for one?

  I want to format due to orders does not and mutiple errors on start up.
  This and it has been incredibly slow. I tried to search for viruses with McAffe and AVG, as well as appropriate Norton and it will not find anything at all, despite the obvious sighs.

  Sorry if this is in the wrong section, I couldn't tell...

  Who and what Set Up Utility?
  Can I use it? When I start my laptop, it's by "menu boot entry.

  Hello

  > So, if I don't have a disc, is it possible to send off for one?
  I put t know what laptop you have, but I guess that your laptop was equipped with HARD drive recovery.
  This allows you to recover the laptop without using any disk recovery.

  Of course, there is an option to create an own recovery DVDs. You read operating instructions!

  From my experience, you could use the preinstalled Toshiba Recovery Disk Creator.

  Good bye
