  • How to know which user object has a LOBSEGMENT given as SYS_LOB0000121913C00011$ $

    Hello

    I'm going to pretend to HW... So far, have been the following:

    1. Select DBMS_UTILITY. DATA_BLOCK_ADDRESS_FILE FOLDER (ID2) #.

    DBMS_UTILITY. DATA_BLOCK_ADDRESS_BLOCK (ID2) BLOCK #.

    the lock of v$ where type = "HW";

    11 1930

    11 1930

    11 1930... 29 documents returned.

    2. Select the owner, segment_type, nom_segment from dba_extents

    where file_id = 11 and 1930 between block_id and block_id + blocks - 1;

    MuUser LOBSEGMENT SYS_LOB0000121913C00011$ $

    But, now how can I find the object (say, table column and lob)?

    Also I used SAMS and LMT.

    Use the built-in DICT display for information on items in the dictionary

    Select * dict where table_name like '% LOB % '.

    results in DBA_LOBS and USER_LOBS

    and BINGO

    Often, there is no need to ask here, you have to just learn to use what is already there (and has been documented)

  • How to know which version of DirectX is installed in Windows 7

    HOW CAN I FINDOUT WHICH IS the TYPE OF VERSION of DirectX

    INSTALLED ON MY PC

    Took me some time to find the answer on the microsoft site, but here it is.

    To use the DirectX Diagnostic tool to determine the version of DirectX installed on your computer, follow these steps:

    1. Click Startand then click run.
    2. Type dxdiag, and then click OK.
    3. On the System tab, note the version of DirectX displayed on the DirectX Version line.
    4. On the DirectX files tab, check the version information for each DirectX file.
    5. When you are finished checking file versions, click exit.

    If Windows cannot find the dxdiag, version 5.0 program or an earlier version of DirectX is installed on your computer. If this is the case, download and install the latest version of DirectX.

  • How to know which card, layout or a collection is changing

    After using the DPS 2015 intensely, I found one of the most difficult things is to lose track of what map, collection, or layout, I'm editing right now. When I click on a map to change, I know at this time what card it is of course, but as I plow through all the options of the map, it's easy to forget which card I'm working on, especially if I am stopped. It would be awesome if at the top of the screen (maybe just side of the "map properties", "Collection" or "Available properties" indicator that appears in the upper left corner of the screen) the title of the map, collection or a layout being edited was posted. That would be really helpful.

    Good suggestion! I spent this on Andrei, who is owner of this area of the product.
