[CARS] Add the new disk in the database running environment

Hi all

I want to ask a question about oracle RAC especially to add a new disk.

Here's the situation for existing oracle RAC

1. There is 1 oracle clusterware (CRS), ASM and 2 node RAC

2. There is a demand to add a new disk to existing diskgroup

3. all CRS, ASM and RAC is in the online state

I read document oracle (How to add a new disc to year Diskgroup existing RAC Cluster or stand-alone Configuration of ASM (Best Practices).) (Doc ID 557348.1()

My question is,

1. that I should stop the database, ASM and CRS when add a new disk to existing diskgroup?

2. are there steps that has already been proven to add a new disk in an operational environment?

Thank you

Adrian

My question is,

1. that I should stop the database, ASM and CRS when add a new disk to existing diskgroup?

No, you need not bring down the ASM or DB

2. are there steps that has already been proven to add a new disk in an operational environment?

Yes, you can add the disk, ASM automatically rebalance and share the workload on the new disk.

http://docs.Oracle.com/CD/B28359_01/server.111/b31107/asmdiskgrps.htm#OSTMG10070

There are number of blog posts about adding disks in a diskgroup

  • Add a new disk to RAID5 on HP DL580 G3 w / ESXi 3.5

    My DL580 G3 currently has 130GB of usable with a RAID 5 configuration space. 3 x 72 GB disks.  I intend to add a fourth Ultra 320 SCSI 10 K 72 GB for additional local storage.

    The DL580 has a Smart Array 6i controller. When I boot the DL580 I see no option of RAID as an Array Configuration Utility configuration. This box came to me with the already configured RAID5 array.

    Would I be able to add a new disk using a Smart boot CD that ACU to extend the RAID 5 set? If Yes, what version of SmartStart?  I did not see one for ESXi or ESX on the site Web of HPs. is there another method that I need to use to expand the RAID5?

    THANKS :)

    If you do not see the utility of configuration of the adapter for the POST/BIOS screens? Pressing F8 does not work either?

    You should have received a Smart boot boot CD with and in most cases, the Raid configuration is possible with this Smart Start.

    If nothing happens, you could build a UBCD4Win and integrate HP Array. I did it for a Smart Array e200i, but only the cmdline versions works well. The GUI version has some limitations on the display of pop-up windows.

    You must save / move your guests as there is no migration of the vmfs online!

  • Size limits to add a new disk to a virtual machine?

    Hello again,

    I have a variety of iSCSI LUNS, and range in size from 500 GB to 1 TB. I've added databases on appropriate LUNS and they were put into shape with a block size of 8 MB he. The problem I encounter is that I can't create a new disk for any computer virtual size of disc more than 256 GB. No clue as to why this is happening? I've recently updated my ESX host with the update package now, cordially.

    Thanks as always...

    I would check that the size of the block is really 8 MB...

  • recover the database running on pfile

    Hi all

    I have an of Oracle (9i) database that was running on pfile (startup pfile = ' path/init.ora'), windows.

    the database has been works well, for several days and today was arrested by a developer (ora-30036 was obtained and it instead of asking any stop just s/n of the database).

    I want to know if I have the database using pfile, will, I get the data to date or I'll have to recover data using the starting log Archives or other methods of recovery?

    1 thing to mention, RMAN is not configured...

    Please let me know if you need more information.

    Thank you

    Florent

    Hi Florent.

    ORA-30036: unable to extend segment by string in undo tablespace 'string. '

    Cause: the specified undo tablespace has no more space available.

    Action: Add more space for the undo tablespace before retrying the operation. An alternative is to wait for all of the active transactions to commit.

    It is not necessary to perform a recovery, you can just start your DB and your DB should start very well.

    If you want to diagnose why you received the ORA-30036, you can start by checking the size of the undo tablespace and check operations that are exhausting your Undo tablespace.

  • Impossible to add the database in enterprise manager 12.1.3

    Hi all


    I recently installed 12 c (12.1.3) on rhel 6.2 oem 64 bit.

    DB version is 11.2.0.3.0

    I've added a target.

    I went to (top - right)

    Configuration-> add target-> manually add target.

    And the agent has been installed successfully.

    However after that once I come to

    (Left side)

    Target-> data-> add-> Oracle database

    I'm not able to see the host name that was added.

    Help, please.

    Thank you.

    If the agent has installed successfully, to connect on the Server DB and goto AGENT_HOME/bin and see the output of the emctl status agent and see if the agent is able to connect to the OEM and also able to download data to the SGD server. Try to stop and start the agent and see if there are errors seen on DB host.

    To add a database to the OEM make you also entered it in the file/etc/oratab on the DB server.

  • Add the RAID 5 disk in an array without openmanage

    Hi can anyone tell me if its possible to add a new disk to a RAID 5 existing table on a server without using poweredge dell openmanage software. The reason is that I am that it is almost impossible to get openmanage installed down to questions of sql and missing installation files. I'm not a DBA and that society relies completely on a sql server for all its activities on the day the day I don't want to change the Setup on sql server options.

    OMSA didn't need SQL. I think that you install rather OME (OpenManage Essentials). OpenManage Server Administrator (Managed Node) is what you need.

    You can do this on some newer controllers, but without knowing what system and controller you have, hard to say. Nothing more than 3-4 years need OMSA. You can also use a live disc OMSA to start education reconfigures.

  • EM12C - add repoitory database as the target of the database

    Hi all

    My apologies if this sounds like a stupid question.

    I just installed EM12C SGD and database repository on the same server (Linux x86_64). The installation is successful and I can access the control of cloud and see targets preconfigured (from the same host).

    However, I am not able to add the database reporitory as the target of the database. Should it? I remember in the 10g grid control, I was able to configure the database reporitory as a target database.

    12 c, I tried "Add manually targets" or "auto-discovery", but none of them show either the database repository or ist listener as target.

    Thanks in advance.

    p.s. I added also successfully 12 c as part of the installation of EM12c agent and the agent is running correctly on the host computer.

    You can use emcli add_target

    Thanks in advance for any help.
    Kim

    Hi Kim,
    I had the same problem with APEX and an upgrade from 9i to 10 g 2. The solution was to re - run that 3.2 installation process after that the upgrade was complete with the same settings as you did the first time. I'm not sure of your upgrade steps, but the best thing to do would be to make the database upgrade (9i-> 10 g 2), then apply the upgrade of the APEX 3.2. It should solve your problem, even if it seems crazy enough.

    Thank you

  • Is it possible to install several facilities of the database on Windows?

    Hello world

    I have a Windows Server 2008 with Oracle 11 g R2 (11.2.0.3, Standard, 64 - bit) database. I need to install an additional database (11.2.0.3, Standard, 64 - bit) for tests on the same server. These tests are patches of database, which will first be applied to the new database before applying these fixes on the existing database, in order to assess potential problems after having patched.

    I'm used to install, configure and manage databases Oracle as a stand alone, RAC or physical standby via the DataGuard since 9i - as long as I'm in a UN * x / linux environment (Red Hat Enterprise Linux, CEntOs, Oracle Enterprise Linux, etc.). Implementation of multiple instances in a single or multiple homes has never been a problem for me so far.

    I already searched google, oracle.com and other related proceedings. But I have found no results on the installation of two or more homes to Oracle under Windows. I found the guidelines on copying / cloning an instance in a new home, but if I remember correctly, it is intended for copying / cloning on other servers and not on the same server. Given that the existing database is installed on Windows, I'm afraid I can damage the existing installation to rerun the configuration wizard, change the registry values for Windows, and the database running as a service.

    Is it possible to have several houses of the same Oracle database, with even the version, edition, and the archiecture (11.2.0.3, Standard, 64 - bit)?

    If so, how can I get it?

    Best regards

    Crazy bytes

    You can run the Setup utility again and specify a different Oracle home. In fact, the installer can provide a different name automatically for you. It's been a while since I've done it, so I'm a little fuzzy on the details. How the two facilities are managed by different registry settings, such as ORACLE_HOME0 and ORACLE_HOME1.

    Another caveat is that when the management of these cases, make sure you start the utilities for each database to its respective home. So, in the menu start, you choose tell SQL * menu Dbhome1 more to manage a single instance and SQL * in the menu of dbhome2 to manage the other instance. It's so environment variables get ready properly before the application starts.

    Hello

    you kill the instance or has he stopped?

    If you stop it then it is planned. You must move the service first.

    If the instance is aborted abnormally (or the server is killed) it should failover.

  • "Cannot find server" when connecting to the database homepage

    Until someone tells me to look at the other post on the first page of the forum with a similar title... I've already read through it. I also did a search of the forum, but I'm still stuck.

    Let me start by saying that I have almost no experience on one database other than writing queries. I installed Oracle Express 10 g today for I can have access to a development environment to test my queries on the sample data. After installation, it automatically opens a web browser, pointing to the URL: http://127.0.0.1:8080 / apex, the page could not be loaded (error Internet Explorer: "cannot display the page." and at the bottom of the page: "Cannot find server or DNS error"). I decided to restart my computer to see if that would make a difference. Then, I opened the link 'Start' in my Start menu in the new folder of Oracle. It instructed me to first of all, go to the home page of the database (with the same URL: http://127.0.0.1:8080 / apex), and the page still doesn't load. Based on the posts that I could find on the subject, I chose "Start Database" of the Oracle folder in my Start menu. In the command window that pops up, he says:
    C:\oraclexe\app\oracle\product\10.2.0\server\BIN>net start OracleXETNSListener
    The requested service has already been started.  
    
    More help is available by typing NET HELPMSG 2182.
    
    C:\oraclexe\app\oracle\product\10.2.0\server\BIN>net start OracleServiceXE
    The requested service has already been started.
    
    More help is available by typing NET HELPMSG 2182.
    Then... It looks like the database and listener are already started, so I don't think that's the problem. So, I'm stuck. I am trying to access to this on the same computer, I installed it, and I don't plan any time in the future where I will need to access the database remotely because it is just a test environment for my personal use.

    The most recent post on this subject, I saw something to try to go to http://hostname:8080 / apex. And, forgive me if this sounds like a stupid question, but I guess I have to replace "hostname" in this URL with whatever hostname actually is... right? So, uh, how can I know what is the host name?

    Published by: user11033437 on April 15, 2010 13:18 (corrected to default URL)

    Well, looks like the answer to one of the previous questions, "isn't the database running" was ", not really" :(

    If there is no newspaper alerts, there no database, most probably the \oraclexe\oradata\XE\ does not contain. DBF files - try manual cleaning (remove registry entries, the Windows install cleanup, etxc.) following ALL the steps in the http://download.oracle.com/docs/cd/B25329_01/doc/install.102/b25143/toc.htm#BABFFJIB

    And check to make sure that your connection to the PC is in the local administrators group (domain administrator is not enough here) and run the installer... what version of Windows? XP? 2003?
