ASM configuration issues

I'm looking to see what situation is better regarding my ASM configuration and what would the dispatch behavior. I use OEL 5 Update 2 x 86-64 and 11 GR 2 Oracle database and 11 GR 2 ASM.

Configuration 1
4 physical HD RAID 5
4 100 GB LUN
1 disc ASM for each LUN
2 (DATA and FRA) ASM disk groups
2 ASM disks by ASM disk group

Installer 2
4 physical HD RAID 5
2 200 GB LUN
1 disc ASM for each LUN
2 (DATA and FRA) ASM disk groups
1 disc ASM ASM disk group

Question 1:
In configuration 1, given that the ASM disks for group to data disks are on the same physical disks, would be this important cause of hotspots. I understand it undoubttedly would claim.

Question 2:
2 installation, ASM would not fail because it cannot scratched in this configuration with only one disk of the DSO. In other words, the ASM would work but simply tape even if the physical HD underscore aren't be scratched by RAID 5.

Question 3:
What Setup is better in terms of availability and performance?


Thank you.

Please see my previous response on hardware RAID, you must use. It depends on your fault tolerance acceptable device, compared to considerations of capacity and performance, also depending on your storage controller.

The configuration you have provided, I suggest to create 4 readers (LUN LUN) of the same size on your RAID storage space. Then create a large partition on all 4 discs and use for example Linux ASMLib to assign these scores to the DSO. ASM to create a diskgroup (+ DATA) using the 4 ASM disks with external redundancy.

I would not throw the discussion about the location of the ASM parameter in this thread. It's a completely different subject.

  • ASM Configuration prior to installation of Network Infrastructure

    Hello

    I want to install a network infrastructure for a stand-alone server 12 c on a virtual machine, it is a first installation, no front installed Oracle software.

    My problem is on the third screen of the Installer (create the ASM disk group), I can't view the ASM disks and the preinstallation process is not clear to me.

    I defined the systems files/U02, /u03, /u04 and /u05 with the oradata and recovery_area directories (oracle: oinstall) for each /u0 * and I want to use them with the DSO.

    I installed the oracleasm-support and oracleasmlib packages, I executed oracleasm configure with parameters of dba (Group) and oracle (user).

    Question 1: I need to run init oracleasm (with default settings) to create the/dev/oracleasm before launching the installer of the grid?

    Question 2: I run oracleasm createdisk before launching the installer of the grid?

    Question 3: What is the proper syntax for the parameter createdisk command 2nd (/ u02, / dev/map/VG_ORA-lv_u02, / u02/oradata,...)?

    Thank you

    Hi Daniel,.

    There is a lot of confusion here.

    ASM is just another Manager file system offering you a more simple and flexible LUN management. Basically, you choose to transfer your database in the file system (/ u01, / U02, oradata, recovery_area) OR if you choose to use the DSO. If you choose to use the DSO, you must create the ASM diskgroup before installing your database. As you mentioned as part of the installation you need to 'discover' the ASM disks and create the first disk group where the DSO Server settings file is kept.

    To do this you have need of screening to the ASM one or more LUNS that are owner by user oracle. Lets assume you want to create two groups of DATA and FRA disks and make your databsae to use. If you use a virtual machine, you need to create more than two disks. Once you do that you have to idetify them, they will be discovered under/dev/sdX. On the same, you must create a partition to fill the entire disc (fdisk/dev/sdX, n for new, p for primary school, 1 to the first disk, and then you press ENTER twice, finally w for write). Finally, you need to make the new owner devides/dev/sdX1 by oracle (oracle: oinstall/dev/sdX1 chown).

    At this point, you should go back to the installer and change the string of disc asm/dev/SD * 1, this will make ASM read all the first partition of all the/dev/disks in sd. Then, you select the disks that you want to use for the default disk group. This can be repeated for the rest of the disk group you want to create using asmca (asm Setup Wizard) or simply using SQL command.

    oracleasm is the ASMLib that was used as a layer of abstraction to make sure that the device files will always have the correct permissions. Nowadays, making using udev as follows:

    Cat > /etc/udev/rules.d/99-oracle-asm.rules

    SUBSYSTEM is 'block', KERNEL is "sdf1", NAME = "asm_data01_disk1", OWNER: 'oracle', GROUP =: = 'dba', MODE: = "660".

    When you start this matches the device to/dev/sdf1 file and create an other device file under/dev/asm_data01_disk1 with permissions oracle: dba

    Hope this helps, but it's just too much information.

    Kind regards

  • Oracle ASM configuration

    I think I have I need help to get my right to ASM storage. Recently I changed businesses and the new place is a House of Windows, so Oracle databases are all on 2008 R2 machines. I run Oracle RAC on both physical and virtual before, but only in Linux/Unix environments (up to now, I still prefer) so I'm still learning some of the ins and outs. This company seeks also to travel to the RAC, ASM is in the mix. To start my tests, I have implemented an ASM instance for a single host that will eventually become a pole of development taking into multiple databases. However, before I set up data bases, the host is locked up. I think it has something to do with the configuration of the disk, because while the entrapment took place while the virtual machine is idling, several crashes occurred when I try to remove a drive within the ASM. I followed the Oracle documentation for Windows platforms, but this documentation does not offer overview of storage virtualization.

    Here is my configuration:

    VMware: vSphere 5.5

    OS: Windows 2008 R2 Standard

    Memory: 12G

    Storage (SCSI LSI): OS: 60G; ASM: 20G, 5G, 5G

    Oracle Grid: 11.2.0.4 (more January 2014 CPU)

    Oracle database: 11.2.0.4 (more January 2014 CPU)

    Other details (perhaps important, perhaps not):

    (1) I have a large pages activated

    (2) drives are supplied thin. Note, I always thick-stocked my ASM, but our admin SR records. HE made a policy that all disks must be supplied thin for efficiency. I don't know if this could cause a problem.

    (3) I work for have the 3 ASM (20 G, 5 G, 5 G) discs set up on different SCSI controllers paravirtualized (another admin IT - SCSI LSI default policy) because they will be used for the DB, the JOURNAL and FRA respectively.

    (4) the host also has an OEM 12 c Agent installed and running.

    I'm new on the Windows platform when it comes to Oracle (I managed a lot of SQL Server DBs), blocks do not appear to produce any type of data in the logs.

    Found the problem. It's the AV software Nothing to do with vmware, it turns out that).

    Hello

    the problem is the host name of the server is resolved is on the 10.X.X.X network.
    For example, the cluster requires the public network to be on this network. And the error you get, because this network is on DHCP.

    If you have the following options that you can try:
    a.) change the server to have the host name to resolve to the 192.X network
    (b) change the order of the network adapters
    (c.) remove the network 10.X.X.X at the moment of installation

    I am trying to set up a network at home via my WRT310N router N Wireless, but have a somewhat convoluted Setup, go home. More specifically, I have a Verizon Actiontec modem/router combo, G who is serving more than one PC Wired has provided, as well as some wireless clients. I would like to connect the WRT310N the ActionTec router and have a Wireless N dedicated va that can also access the internet, but also a handful of wireline customers. Two routers are connected wan wan port port.

    However, I don't know how to set up the "Internet IP" of the WRT310N so that both routers to communicate between them. If I put a static IP address which is identical to the IP of the router, I get a warning indicating that the internet IP and router IPS are on the same subnet and is not kosher (which I guess makes sense). Define the Internet IP to DHCP function results in no IP being pulled from the Actiontec router (presumably for the same reasons)

    Is anyway to configure the router behaves more like an access point?

    Im just trying to assign static addresses to the side in the 192.168.1.0 LAN range, but it does not seem to carry the traffic from one side to the other. Can it be related to not being able to assign an IP address to all four ports Fast Ethernet (switch)? I get IP addresses cannot be set up on L2 links so Ive vlan1 configuration instead, but that cannot link to any real interface

    Attached is the current running config

    Can as a question you please recommend a good book to learn how to do this sort of thing?

    Thank you

    Hi ports 800 series which are l2 may not take an ip address like you because they are pure switch ports, so if you your using several VLANS part SVI Layer 3 must be set to the router and the switchports to shared resources, if only using the vlan 1 should not no need to trunk or make changes to these default ports , they are in the vlan 1

    You have a switch involved or are your PC connection directly to these ports, you set the gateway default ip address vlan 1?

    The interface vlan 1 shows to the top and to the top when you run int ip see the brief

    VLAN 1 is related to these ports, so when you connect to a pc with a correct address in this range him vlan will come and you should be able to ping from the local pc to the internet

I recently bought this phone and I have never set up a company account. Now I can't access my email via my phone. Any ideas?

    Before you get too deep into what, please call your operator and confirm that you have the blackberry internet service added to your account.  Without this service, you will not be able to email personal to be installed on this phone.  Don't know what else to say on they mention, but you must have BIS added to your account in order to setup email.  Even when a wifi connection.

  • BlackBerry smartphone T-Mobile Pearl 8220 Email configuration issues

    Hello

    When I tried to configure my personal e-mail with my BB Pearl 8220 (T-Mobile), there is no option for a personal e-mail account, only a business account. Can someone help get the personal account option to introduce or know something about it?

    Thank you

    -Dan

    Do you have a data Plan BlackBerry enabled on your account with your carrier or mobile provider?

    You have to, to get the push RIM email functions you are looking for, as well as services of BlackBerry data such as the Web browser, Facebook for BlackBerry, BlackBerry Messenger and much more.

    Then call your carrier and you learn about to have added to your account BlackBerry data Plan.

    Good luck.

    S0/1/0 shows that up but line protocol down.

    Any ideas? Can I not use a WIC-1DSU-T1-V2 in a MLPPP configuration?

    Looks like a carrier problem, check with the carrier the correct/linecode framing are in use and the third circuit is smooth. Config seems good.

    Even if the Interface is up and down and will not join Multilink, another useful command is to see the ppp multilink gives you a quick look at what interfaces are attached to the multilink, just for future troubleshooting.
