How to create VTL and tape drives

hi!
i want to create one library like"vlib" containing two tape drives vt1 and vt2 having equal space of 512 MB.
Can u plz check that i am on right track
ob>mkdev -t library -o -S 2 -a test:/d01/secure/vlib -v vlib
ob>mkdev -t library -o -a test:/d01/secure/vt1 -v -l vlib -d 1 vt1
ob>mkdev -t library -o -S 2 -a test:/d01/secure/vt2 -v -l vlib -d 2 vt2
Insert Volume
now here is where i am confuse .....
ob>insertvol -L vlib -c 512 unlabeled 1-2
now how to insertvol in tapes .....by above command is this volume available to all tapes in that library.
actually i want that i have two tapes vt1 and vt2 ,both should have space 512 mb now when i take full database backup through rman ....after when vt1 becomes full it start utilizing other tape vt2 automatically.
plz helppppppppp

thank you ....but please can u check that what i have done...i am giving detail......plzzz
STEP 1)
ob> mkdev -t library -o -S 2 -a test:/d01/secure/vlib -v vlib
ob> insertvol -L vlib -c 512 unlabeled 1-2
ob> lsvol -L vlib
Inventory of library vlib:

in 2: unlabeled, barcode feef494efdea10285e7000c2944f637
ob> mkdev -t tape -o -a test:/d01/secure/vt1 -v -l vlib -d 1 vt1
ob> lsvol -L vlib -D vt1

* in 2: unlabeled, barcode feef494efdea10285e7000c2944f637
*: in use list
ob> mkdev -t tape -o -a test:/d01/secure/vt2 -v -l vlib -d 2 vt2
ob> mkdev -t tape -o -a test:/d01/secure/vt3 -v -l vlib -d 3 vt3
STEP 2)
Then i created backup storage as RMAN default and selected vt1 as tape.
after that with rman i took full database backup.
ob> lsjob -l

  • How to Create a Bootable Flash Drive to do a clean install of Lion.  I have tried to use the InstallESD.dmg but it still will not do a clean install so that I do not have to do a reinstall from the Recovery (That just re downloads and takes over 6 hours)?

    How to Create a Bootable Flash Drive to do a clean install of Lion.  I have tried to use the InstallESD.dmg but it still will not do a clean install so that I do not have to do a reinstall from the Recovery (That just re downloads and takes over 6 hours)?
    The system I'm have is a Mac-mini that had SL on it and no SuperDrive.  I have also call Apple Support and they have really have not been to much help over 1st did my up grade to Lion and Installed the Lion Server.... it lost my SSL that I paid for and kill almost on of my server setting, plus kill all my web servers (using apache vhosts), and not to say the LDAP will even let remote users login to your laptops.
    PS: There is no way that I'm going to buy a Install USB from Apple... They have over billed me over $300.00 because the Apps Store still has bugs (Glad I did not write that App/Service)
    If there is anyone that can give in the information to create a USB install stick, I would be very thinkful.

    Here you are bro, courtesy of "softpedia.com"....brilliant site!!!
    If you ever had problems with your Mac OS X installation you know that the first thing you should do is to check the startup volume using Disk Utility.
    After the check has ended and, if the errors exceed a certain level of seriousness, the Disk Utility application will require you to restart your Mac and use its Mac OS X Install disc counterpart.
    Other users may have to reinstall OS X altogether, but will find, or already know, that their SuperDrive (a CD/DVD reader and write combo drive) is not functioning properly and it will not be able to read the Install disc.
    Although this might happen to Mac OS X Leopard users due to faultyhardware, the vast majority of problematic SuperDrives will be encountered inside Snow Leopard running Macs.
    This is due to the updated SuperDrive firmware included in either the Install disc or the software updates one has to install to reach the latest version of OS X, namely 10.6.6.
    This can be fixed by flashing the SuperDrive’s stock firmware using free command line tools that one can find for free online (I will write about this process also, but at a later time because this article only focuses on allowing you to create your own alternative USB boot disc).
    If you are reading this last bit of information with skepticism, than you should know that it happened to me too. Despite all my tries to make it work properly, the SuperDrive kept on munching any inserted DVDs and just popped them out in about twenty seconds.
    The workaround to this issue was to create my own Leopard bootable USB memory stick. I am not suggesting a Snow Leopard bootable stick mainly because there are lots of users that have decided to buy the cheaper, Upgrade version, which I have not tested and, therefore, I’m not sure if it will work properly once written to a USB disk.
    And now, here are the exact steps you should follow in order to obtain a fully bootable Leopard (or Lion) Install disc.
    Step 1 (If you already have the Leopard install disc DMG file you can skip to Step 2)
    Launch Disk Utility (you can find it inside /Applications/Utilities). Here select the Leopard Install disc in the list of drives on the left and click on the New Image menu entry at the top of the window. A save message will appear where you will have to select the Desktop as a destination.
    Step 2
    After Disk Utility has finished creating the Leopard DMG, insert your USB stick and erase all data and reformat the disk. To do this select the USB in the list of drives on the left and, after clicking on the Erase tab on the right side of the window, choose the Mac OS Extended (Journaled) format and click the Erase button beneath.
    Step 3
    After the USB has been reformatted, download the SuperDuper app from HERE and launch it. Once SuperDuper starts, you will only have to select the DMG in the Copy drop-down menu, your USB memory stick on the right and hit the “Copy Now” button.
    One can also use Disk Utility for this task but creating a bootable USB stick failed 2 out 4 times when copying the DMG to the stick (with the exact same settings each time). Creating the bootable stick using SuperDuper proved to be the perfect way to do it because it worked each of the 4 times I tested it.
    The steps above can also be used to create a bootable Mac OS X Lion USB by using the InstallESD.dmg image you can find inside the Lion installer (named “Install Mac OS X Lion.app”) downloaded from the Mac App Store in the /Applications folder.
    To locate the InstallESD.dmg right click the Lion installer, select the “Show Package Contents” entry, go inside the “Contents” folder, and from there into the “SharedSupport” folder. Inside this folder you can find the InstallESD.dmg you can use to create your own bootable Mac OS X Lion USB stick. To do so, go to the third step described above and use the InstallESD.dmg as the DMG to be copied to your USB disc.
    That’s it! Once the process ends you will have a fully bootable Leopard (or Lion) USB disk that you can use as an alternative to the Apple’s DVD Install disc that comes bundled with all Macs.
    To use your newly created bootable disk you will have to restart the Mac, press and hold the OPTION key until the StartupManager appears. Here, select the Mac OS X Install disk using your keyboard arrows and press return to start from the selected drive.

  • How to create DataSource  and ConnectionPooling in WAS

    hi,
    can u please tell me how to create connectionpool and data source in WAS.pls send me step by step procedure
    regards
    Guru

    Hi,
    Here is the steps to creat a JNDI lookup using Datasource for MSSQL Server. Follow this and use necessary oracle parameters (in bold) as gives by me in the help link above.
    Click DataSources in the same path i.e. server > services > JDBC connector
    Click “new driver or datasource”.
    Enter/ Set the following properties:
    Main Tab
    DataSource Name : KAAR_DS
    Add Alias : KAAR
    SRI
    Driver Name : KaarSQLDriver
    JDBC version :2.0 (with XA support)
    <b>Object factory : com.microsoft.jdbcx.sqlserver.SQLServerDataSourceFactory
    DataSource Type : ConnectionPoolDataSource
    CPDS classname : com.microsoft.jdbcx.sqlserver.SQLServerDataSource</b>
    Additional tab
    Add the following properties (key-value):
    serverName = localhost
    databaseName = KA4
    portNumber = 1433
    user = CV
    password =<password>
    Save and restart J2EE. The datasource is now ready to use.
    Connection Pooling
    Initial connection : 0
    Maximum connection : 100
    Maximum time to wait for connection : 60
    Default connection isolation : DEFAULT
    SQL Engine
    Select, Vendor SQL
    DB Initialization Tab
    Add a valid sql statement, and execute. If it is successfully executed, a popup window comes up saying Executing “<sql query>” . OK.
    It is done. Now you can use the JNDI look up name in your coding to access the database. Get connection and use the queries to fetch data from db.

    Hi Gurprit,
    A null value is being passed at runtime. Make sure that you enter values when filling in the form.
    Also check for the cardinality of the nodes being used. You can also initiliaze your value attributes as follows:
    In wdDoInit() method:
    wdContext.currentNodeAElement.setValueA("");
    Context is as follows:
    RootNode
      |____NodeA
            |_____ValueA
    Hope it helps.

  • How to create parent and chile process in java

    i'm beginning in java, and i want to ask something, please help me...
    1. i want to ask how to create parent and child process in java???
    example :
    if have one window and explore menu, when i click the explore menu.
    new window come out.
    how if i close the parent window the child window will close too...
    2. what is the method from runtime class to get available memory and Active Threads count

    ONE way to do what you wanted is this.
    class Parent{
    Child c = new Child
    allChildren.add(c);
    //if close
    iterate through list
    (Child)allChildren.get(index).close();
    ArrayList allChildren;
    class Child{
    public void close(){ }
    i dont know if you can get the thread count. but you can
    get the current thread by using System.
    Memory: Runtime.freeMemory() .maxMemory() .totalMemory()
    http://java.sun.com/j2se/1.4.2/docs/api/java/lang/Runtime.html
    Careful though you have to do a calculation to get the
    actual memory because those 3 methods refer to freeMemory
    of the CURRENT heap not the total memory.
    i think its: total - (max - free)

    My problem is when I create a parent and then right away a children. The parent still not have a primary key until the transaction get to the database. I get a error when trying the create the children, cannot insert null in the foreign key field of the children.
    Please help.
    Stephane

    You should have the parent key be marked as a DBSequence type.
    Then you should have the association between the master and detail defined as composite association to make sure that the posting order to the database is correct.

    Thanks in advance.
    Regards,

    Hi,
    Could you please re-phrase your question? As the report painter is a reporting tool I assume you want to report on P&L accounts and not u201Ccreateu201D them. A few more details on what you intend to report would be useful.
