grid below 11 GR 2 helps the installation required

Mr President

I have some problem.do don't know don't not how to solve?

I need to install the Advanced installation grid infrastructure.
Scenario and question:

I have a raw(74GB) under the DSO on 192.168.1.13.but how to implement cluster is not under OCFS2, what to do (under OEL5.4)?

and in another machine (with ip 192.168.1.30) I want to load 11 GR 2 grid as well as 11 GR 2 db but how would you describe the disk to ASM-ocfs2 cluster? I had an a partition/dev/sda3 as LVM with two partion mounted /ASM1 and /ASM2 empty ext3 in this machine.what do?

concerning

To identify storage needs for the use of Automatic Storage Management, you must determine the number of devices and the amount of free space on the drive you need. To perform this task:
1. determine if you want to use Automatic Storage Management for Oracle database files, recovery of files or both.
Note:
You don't have to use the same storage mechanism for Oracle database and file recovery files. You can use a file system for one type of Automatic Storage Management and file for each other.
If you choose to enable automatic backups and you don't have a system of shared files available, you must choose Automatic Storage Management for the storage of files recovery.
If you plan to activate backups automated installation, then you can Automatic Storage Management as storage of file recovery mechanism by specifying a group of Automatic Storage Management disk for fast recovery area. Depending on how you choose to create a database during installation, you have the following options:
o If you select an installation method that runs Oracle Automatic Storage Management Configuration Wizard in interactive mode, you can decide if you want to use the same disk group Automatic Storage Management for data files and recovery files, or you can choose to use groups of different record for each file type. Ideally, you should create separate Automatic Storage Management disk groups for the data files and recovery files.
The choice is available if you are using Oracle Database Configuration Wizard after the installation to create a database.
o If you select a type of installation that works Automatic Storage Management Assistant de Configuration Oracle silent mode or in answer file mode, then you must use the same disk group Automatic Storage Management for data files and recovery files.
2. choose the level of redundancy of automatic storage management you want to use for each Automatic Storage Management disk group that you create.
The level of redundancy you choose for the Automatic Storage Management disk group determines how Automatic Storage Management reflects the disk group files and determines the number of disks and the amount of disk space you need, as follows:
o external redundancy
This option does not Automatic Storage Management reflect the content of the disk group. Oracle recommends that you select this redundancy when the disk group contains devices, such as the RAID devices, which protect their own data or when the database does not require uninterrupted access to data.
o Normal dismissal
To optimize performance and reliability in a group of disks in normal redundancy, Automatic Storage Management uses two-way mirroring for three-way mirroring for the default control files and data files. In addition, you can choose the features of mirroring for individual files in a disk group. You can also use the bidirectional or not mirror mirrored.
A normal redundancy disk group requires a minimum of two groups of failure (or two drive devices) If you use two-way mirroring. Effective space in a disk of normal redundancy group is half of the sum of the space in all of its features.
For most installations, Oracle recommends to use normal redundancy disk groups.
o high redundancy
The contents of the disk group is three lanes in reverse by default. To create a disk with high redundancy group, you must specify at least three groups of failure (a minimum of 3 devices).
Although disk groups high redundancy offer a high level of data protection, you must take into account the higher cost of additional storage devices before you decide to use this level of redundancy.
3. determine the total amount of disk space you need for database files and recovery files.
If an Automatic Storage Management instance is already running on the system, you can use an existing disk group to meet these needs of storage. If necessary, you can add disks to a group of existing installation drive.
Use the following table to determine the minimum number of disks and space of minimum disc required for installation:
The two Types of files the files number Minimum level of redundancy of records data files recovery
External 1 GB GB 5.4 GB 3.6 1.8
Normal 2 3.6 GB GB 7.2 10.8 GB
High 3 5.4 GB GB 10.8 16.2 GB

4. If necessary, identify the groups of failure for devices of Automatic Storage Management disk group.
If you plan to use a normal or high redundancy disk group, you can further protect the database against hardware failures by combining a set of disk devices in a custom group failure. By default, each unit includes its failure. However, if two drive devices in a group of normal redundancy disks are attached to the same SCSI controller, then the disk group would become unavailable if the controller fails. The controller in this example is a single point of failure.
To avoid failures of this type, you can use two controllers SCSI, each with two discs and define a group of failure for the drives attached to each controller. This configuration would allow the disk group to tolerate the failure of a SCSI controller.
Note:
If you set custom failure groups, you must specify a normal minimum of two groups of failure for redundancy disk groups and three groups failed for disk groups high redundancy.
5. If you are sure that a suitable disk group does not exist on the system, then install or identify the drive devices appropriate to add a new disk group. Apply the following guidelines when identifying the appropriate drive devices:
o disc devices must belong to the user who performs the installation of the grid.
o all devices in an Automatic Storage Management disk group must be the same size and have the same performance characteristics.
o do not specify several partitions on a single physical disk as a disk device group. Automatic Storage Management expects that each device group on a separate physical disk drive.
o Oracle does not recommend the use of a logical volume as a device of automatic storage management, because the logical volume is able to hide the physical disk architecture that prevents Automatic Storage Management of I/O optimization across physical devices.

  • Cannot install Trend Micro 2012, receive error message: "your computer meets all the installation requirements, so Setup must stop."

    Original title: Problems installing Trend Micro 2012

    Tried to install Trend micro on my laptop, and towards the end of this way the message; "Your computer meets all the installation requirements, so the installer must stop." appeared. He then read "Windows update," I clicked on the link and also called microsoft who gave me the link updates from SP1 to SP2. I did (ran for almost 2 hours!) and recorded. I then checked the edition of windows under system and it has not saved the update even if it is registered and installed to my files. Tried to do the foregoing twice, still the same problem. Rang Dell and they sought to find an answer to the problem, but did everything they could. Still no answer to the problem after all. I have Windows Vista Home Basic as my operating system and installed Trend micro in the past with no problems. (Not sure if the following has nothing to do with it, but thought it might be useful a mention). I changed to Microsoft Office 2007, which has already been installed on my laptop for Office 2003, because I found it difficult from the laptop to the desktop and I didn't really want to pay for the upgrade of my office, if I didn't need it.

    Hello

    Even if you have the new hard drive attached, and where he does not receive on-screen detected (you don't say "no driver cannot load"), want to confirm if you have the drivers for the hard disk and use the driver to load on the screen.

    Hope you follow the step as below:

    Note: To configure the installer of Windows Vista to use the specific driver, click on load driver to load the specific driver of the media that should be inserted in the CD/DVD drive.

    As you say you updated to Vista, would like to know the brand and model of the computer and the operating system that was more early to see if we could add more suggestions to help you here.

  • How do I install the drivers during the installation of windows 7

    I did an install home premium windows 7 dvd by burning a file .iso I downloaded on a dvd and I am facing problems installing drivers. I extracted the drivers on an external hard drive and installing windows 7 they ask me about the drivers before installing windows.
    I have all the drivers in the external hard drive but I tried several times to install them using the button browse and locate the folder that contains every driver and install it alone, but his does not work. So is there a better way to install the drivers?
    Thanks in advance

    Hello

    During the clean install of Windows 7, users are generally required to install a few drivers for the internal hard drive. These drivers must be written to a DVD disc / USB key and installed when prompted.

    In this case, I believe, is that you are trying to install the wrong drivers. The installation requires the internal hard disk drivers. This driver will depend on the configuration of the internal hard drive (RAID, SCSI, etc.).

    Another possibility could be that other equipment are not properly recognized by Windows 7 installation. You try to install Windows 7 and burn the ISO on a USB bootable and start the computer to the top of this USB key. Here's how you can do:

    Question2.

    Currently shared LUNS appear in the form

    / dev/sdb.

    / dev/sdc.

    / dev/sdd

    is a single partition must be created before LUNS to ASM?

    For example, I should choose p (primary partition) below. Right?

    # fdisk/dev/sdb

    Device contains a table of the MS-DOS partitions, valid Sun, SGI, or OSF disklabel

    The construction of a new partitioning BACK with disc 0x8b157fd2 identifier.

    Changes will remain in memory only, until you decide to write them.

    After that, of course, the previous content is not recoverable.

    WARNING: The DOS compatible mode is discouraged. It is strongly recommended to

    off mode (command 'c') and change the display units to

    sectors (command 'u').

    Command (m for help): c

    Indicator of compatibility BACK is not defined

    Command (m for help): u

    Change of units of display/entry to the sectors

    Command (m for help): n

    extended e

    p primary partition (1 - 4).

    Check step 5 here. You use oracleasm utility that changes the permission.
