  • How to find the number of ODBC connections to Oracle Database

    Hi All,
    How to find the number of ODBC connections and all connections to the Database in last week. Are there any views to get this information?
    Thanks in advance,
    Mahi

    What Ed said is true that Oracle doesn't note which type of protocol is connecting to the database, however, you can see which program is accessing the database.
    For example: if you already know of a user using ODBC, you can verify as:
    select username, osuser, terminal, program from v$session where username = 'SCOTT'
    USERNAME                 OSUSER          TERMINAL   PROGRAM
    SCOTT                    IUSR_SRV231     SRV231     w3wp.exe
    SCOTT                    IUSR_SRV231     SRV231     w3wp.exe
    2 rows selected.Assuming that you can confirm the progam noted in the above (example) is the one using ODBC, then you can change the query such as:
    SQL> select username, osuser, terminal, program from v$session where program = 'w3wp.exe';
    USERNAME                 OSUSER          TERMINAL   PROGRAM
    SCOTT                    IUSR_SRV231     SRV231     w3wp.exe
    SCOTT                    IUSR_SRV231     SRV231     w3wp.exe
    2 rows selected.Just for kicks, I checked our listener.log file, but there was no reference of odbc in it either.
    Hope this helps...

  • How to find the number of data items in a file written with ArryToFile function?

    I have written an array of number in 2 column groups to a file using the LabWindows/CVI function ArrayToFile...Now if I want to read the file with FileToArray Function then how do I know the number of items in the file. during the write time I know how many array items to write. but suppose I want the file to read at some later time then How to find the number of items in the file,So that I can read the exact number and present it. Thanks to all
    If you are young work to Learn, not to earn.
    Solved!
    Go to Solution.

    What about:
    OpenFile ( your file );
    cnt = 0;
    while ((br = ReadLine ( ... )) != -2) {
    if (br == -1) {
    // I/O error: handle it!
    break;
    cnt++;
    CloseFile ( ... );
    There are some ways to improve performance of this code, but if you are not reading thousands of lines it's quite fast.
    After this part you can dimension the array to pass to FileToArray... unless you want to read it yourself since you already have it open!
    Proud to use LW/CVI from 3.1 on.

  • How to find the number of links in a website

    hi every body
    can any one clear my doubt
    my doubt is that
    in a website how to find the number of links the hole website contains
    is there any navigation tool to find that
    plz help me yar
    i am waiting for the reply

    If you're talking about commercial sites (sites you don't have the source code for) I'm not sure.
    If you want to count the links in site that you have the source code for, it should be relatively easy to write a Java application to do it. All you really need to do is have a list of the files you want to count links in, read each file line by line and check for the existance of the <a> tag in each line. Anywhere their is an <a> tag there is a link.
    Hope this helps.

  • How to find the number of records per months  in cube

    Hi,
      how to find the number of records per months for my all cubes?
      Can i use the ListCube transaction to find totl number f records per cube monthwise ?
    Jimmy

    Hi,
    Here is a program to generate no of records and list of ODS and Cubes in Active version.Schedule this program in background and create a cube to load this information and schedule to the data from the file generated by the program. Schedule this all per you requirement.
    1.Copy the code into your Z<programname> from Se38.
    2.change the FILENAME in CALL FUNCTION 'GUI_DOWNLOAD' in the program to the location from where you can pick the information to load data to cube(eg Application server).
    3.Save program.
    4.Schedule the program in background as required
    5.Create cube with infoobjects to hold no of records and Infoprovider name
    6.Load this cube based on event after the program job is done.
    Hence you can report on this cube to see no of records in  CUBE or ODS in your box.
    Please find the code below.

  • [Win VC++ 6.0 ]How to get the number of files count in a folder using VC++ 6.0?

    Hi all,
    Can any one tell how to get the number of files(.EPS) count inside a folder when the folder path is specified in VC++ 6.0?
    Thanks in Advance.
    Regards
    myriaz

    I'm a little confused by the question, but it sounds like you're asking how to count the number of files with a particular extension in a given directory? That's not really an AI SDK question, but it's a fairly easy one to find if you google it. If you're trying to use Illustrator to do it, AI doesn't have a general purpose file API. It has a few functions to do some things that Illustrator needs, but I don't think enumerating directories is one of them.

  • How to find the number of entries in a master data table

    Hi Experts,
    I am trying to find the entries in 0CUSTOMER master data.
    BW>LISTCUBE>Data target: 0CUSTOMER and selected the fields that I need.
    I would like to know how to find the "number of entrees". I tried to run the SUM for a count field, but it is taking forever as there are huge number of records .

    Hi Dev,
    Go to the change/display mode of the info object (0CUSTOMER) in your case. Go to the Master data/Text tab. Here you will find the master data tables according to your settings (P orQ or X or Y). Double click on the table name and it will take you to the SE11 display. From there, you can check the number of records as you do in any transparent table.
    Hope this helps.

    How To Ask Questions The Smart Way
    Eric Steven Raymond
    Rick Moen
    Write in clear, grammatical, correctly-spelled language
    We've found by experience that people who are careless and sloppy writers are usually also careless and sloppy at thinking and coding (often enough to bet on, anyway). Answering questions for careless and sloppy thinkers is not rewarding; we'd rather spend our time elsewhere.
    So expressing your question clearly and well is important. If you can't be bothered to do that, we can't be bothered to pay attention. Spend the extra effort to polish your language. It doesn't have to be stiff or formal ? in fact, hacker culture values informal, slangy and humorous language used with precision. But it has to be precise; there has to be some indication that you're thinking and paying attention.
    Spell, punctuate, and capitalize correctly. Don't confuse "its" with "it's", "loose" with "lose", or "discrete" with "discreet". Don't TYPE IN ALL CAPS; this is read as shouting and considered rude. (All-smalls is only slightly less annoying, as it's difficult to read. Alan Cox can get away with it, but you can't.)
    More generally, if you write like a semi-literate b o o b you will very likely be ignored. So don't use instant-messaging shortcuts. Spelling "you" as "u" makes you look like a semi-literate b o o b to save two entire keystrokes.

  • How to find the number of fetched lines from select statement

    Hi Experts,
    Can you tell me how to find the number of fetched lines from select statements..
    and one more thing is can you tell me how to check the written select statement or written statement is correct or not????
    Thanks in advance
    santosh

    Hi,
    Look for the system field SY_TABIX. That will contain the number of records which have been put into an internal table through a select statement.
    For ex:
    data: itab type mara occurs 0 with header line.
    Select * from mara into table itab.
    Write: Sy-tabix.
    This will give you the number of entries that has been selected.
    I am not sure what you mean by the second question. If you can let me know what you need then we might have a solution.
    Hope this helps,

  • How to find the number of occurance of a string in text field of Infopath form?

    Hi All,
    In Infopath text field, How to find the number of occurrence of a particular string in that field?
    Thanks in advance!

    You can check to see if it contains a string once by using the contains function, but there isn't a very clean way to do what you want. If you wanted to guess at the maximum number of occurrences, then you could:
    Box A has your initial. Set Box B to do a concat of string-before and string-after of Box A where it copies Box A minus the string we're looking for. Then we have Box C that does the same thing to Box B. Repeat as many times as you see necessary.
    Example:
    String: "1"
    Box A - "123451234512345"
    Box B - "23451234512345"
    Box C - "2345234512345"
    Box D - "234523452345"
    etc.
    We then have a field that has nested ifs looking backwards from Z -> A looking for a non-blank. Based on that, we return the number of occurrences. Again, this isn't clean, but it will work if you think there's a predefinable maximum.
