• Configuration of the laptop for R12 with node 2 11g RAC database

  Hi all
  
  I plan to buy a new computer dell laptop XPS to install Oracle Apps R12 with node 2 11g RAC DB by creating virtual machines.
  
  Configuration:
  

  generation of Intel processor i5-2410 2 (2.3 GHz, core 2, 3 MB cache)
  8 GB RAM DDR3
  750 GB HARD drive

  this configuration will be sufficient for the highest installation? RAM? Processor?
  
  I've read a few threads over on this forum where people have recommended for installation of single application (11i or R12), this kind of configuration can be enough.
  
  Please answer.
  
  Thanks in advance.

  You need at least 4 GB for installation on a single node R12. So, if you plan to have 3 VMs (1 application node) and 2 RAC nodes or 4 virtual machines (2 application and 2 RAC nodes), then I suggest that you add more memory. However, your RAM should work, but don't expect (if you go with 3 VMs) but do not expect the performance to be perfect.

  I have one remember off the top of my head...

  For practical reasons, the answer is Yes.

  -UO should have attended the training course...
  - or you should have been a DBA OCP 11 g (and training is required for that, unless you certified a long while ago as a 7(8?)) OCP DBA before the obligation and have updated become 11 g DBA OCP of updates)

  Mandatory training for the certification of EBS in class? (R12)

  I do not remember / do not know that out of my head.

  But websire Oracle tells you:

  Visit http://certification.oracle.com

  Looking for certification... and mandatory training will be detailed here.

  The required courses are detailed.

  If so, then what is the cost for this...

  http://education.Oracle.com will give details of the courses and training costs for your country.

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

  I need to understand the infrastructure Oracle RAC and grid, a manager / training perspective.

  I see links here and here , so a few questions:

  -What is the fundamental difference from the layman's point of view (for example, a Manager)?

  -What training options are available for a generic 11g DBA to learn this new technology? I've seen this course from a partner of Oracle ("" courses: Oracle 11 g: RAC and Grid Infrastructure Administration accelerated Release 2 ""), to a boat load of money, during 5 days I think. So we are looking for something a bit more reasonable (and accessible), for example, books, online, etc.

  For a very basic definition, ACR is technology that is used by the database and IM is the infrastructure that makes the CAR work. In a response to the forum, this is probably all that can be said about the two. For a very long answer, you should read the links you cited.

  # 2, the course you are looking at is called accelerated because it combines two courses in one week training-RAC (4) and GI (3). So it's a day 7 curriculum that we would do in a 5 day course and who must justify its cost. But let me say, it's a really very good. But on the other side, it can be pretty intimidating to someone who does not already know these technologies. So I suggest that you send your team to each course individually and no doubt after doing some research. They can start to read the following books

• Deployment of Oracle 11g RAC Release 2 with IBM midsize V7000

  At and deployment 11g rac with IBM midsize V7000 san with aix 6.1
  Is this possible using Oracle CRS without going to the OS like GPFS cluster

  Oracle Grid these days use ASM starts for vote and register files storage. So no need for a cooked cluster file system that must be mounted by all nodes. No need either directly with a gross storage logical unit number.

  ASM uses the LUN of the matrix of storage/SAN directly (as devices of rough blocks).

  Generally however, there are several I/O paths to that LUN on the SAN - in which case there is more than 1 device level o/s for this LUN. Multipath driver s/w addresses this and creates a logical (and redundant) device that sits at the top of several devices of i/o path to the level of the o/s.

  You configure ASM to use devices of paths multiples (as devices of rough blocks) - and applying exterrnal, normal or high redundancy necessary when creating starts on these logical multipath devices.

  The grid s/w and RAC database instances can then use ASM starts as cluster storage.

  This makes storage much easier layer management - and also provide a number of useful features too.

  This is also the approach recommended by Oracle Corp. for RAC - use ASM under the layer of management of storage between storage LUNS in the table and one side and CARS on the other.

• 11g RAC - RAW Devices Configuration

  Hello
  
  Please let me know if there is a difference in the configuration of RAW devices for 11g RAC compared to 10g.
  For example in 10g, we would separate RAW Devices for OCR, voting disk, ASM spfile, archives log files and database files.
  
  Please let me know if configuring RAW devices in 11g is different from that of 10g.
  
  Kind regards

  Published by: user7202581 on April 19, 2011 23:54

  Hello

  all first with 11.2. directly use the RAW devices is no longer supported. However, you can use RAW devices below ASM. So if you use ASM for data files, archivelogs etc, then the ASM disks can be RAW devices.
  Second: A general comment on Linux RAW devices. Have become obsolete from CRUDES Linux devices (I think with RHEL 5.3), so I recommend the direct use of block devices (which is possible since 10.2.0.2).

  No to your question:
  With 11 GR 1 material has not changed the configuration of the CRUDE devices.
  With 11 GR 2, the configuration has changed. See the Grid Infrastructure Installation Guide for additional and accurate information (on the installation, rights of user etc.).
