How many users are connected

Hello

How we can find that how many users are connected to a database in a rac system and how many users are connected to the particular node.

Thank you!

session request gv$

Select count (*) in the session $ v where username! = "SYS."
SELECT count (*), select INST_ID GV $ session where username! = "SYS" group by INST_ID select;

SQL> select count(*),inst_id from gv$session group by inst_id;

  COUNT(*)    INST_ID
---------- ----------
        48          1
        39          2

    Could you help me, I want to know how many users can connect to these routers:

    Concerning

    Thanks for the info.

    I recommend that you include in your comment and possible purchase router, a router of class business. EA and WRT series routers are routers of class home and can't function in a class environment business or offer what you need in a configuration of class business. I recommend that you call, contact Linksys or sales support and ask them what model router would be better suited to your needs before you buy. Would avoid probably no dispute afterwards. Good luck.

    Isn't beautiful! I just wanted to share this.

    Now, what would be really great, is if we could run off statistics on how many people is connected at some point in the day. We are able to report on the user login time and their time of disconnection in any logon and the band upwards in this way. However, if John D connects to 09:00 and 10:00 out newspapers, we would expect to be counted at 09:00, 09:15, 09:30, 09:45 & 10:00 when he was for that entire period.

    We do not know if this is possible, but any help is really appreciated.

    Thank you
    Lloyd

    Hello

    I guess you have the logon_time and the logoff_time in your folder and you want to add up the number of users when connected on every quarter of an hour during the day.

    To do this, you must use a generator of line because there is a line for once connected to an hour, but it takes five times for each quarter of an hour. You can use a custom line generator folder. It's just a folder that will always return a fixed number of lines. You will need to create a Dumpy field in the custom folder of row_gen to join your existing folder. In this example, I created a dummy scope recurring X. You can then create a calculated item in your folder which also always returns X and join the two files together using this fake field.

    The line generator must create a line for each quarter during the day. For example,.

    SELECT 'X' model, TO_CHAR (hrs, 'fm00') |': ' | To_char (MN * 15, 'fm00') hhmm
    FROM (SELECT rownum-1 hrs OF DOUBLE CONNECTION BY ROWNUM<=24)>
    (SELECT rownum-1 mn DOUBLE CONNECTION BY ROWNUM<=4)>

    You can reach this custom in your timings folder folder using the dummy field, but also include extra in your workbook join conditions so that there is a line that is generated for each quarter that the user is connected. There is some complexity if the user logs on another day. The join conditions must pick up all the lines power supply line for the duration of the user session. So you need to get conditions like this:

    (logon_time<= logoff_time="" --="" logged="" on="" and="" off="" on="" the="" same="">
    AND (row_gen.hhmm BETWEEN logon_time AND logoff_time))
    OR
    (logon_time > logoff_time - logged on and off the different days)
    AND (row_gen.hhmm logon_time TO 23:45 ')
    GOLD row_gen.hhmm BETWEEN ' 00:00 ' AND logoff_time))

    You can then include the row_gen.hhmm report and count the number of users. This will give you the number of users connected to each quarter throughout the day.

    By the way you do not have a big decode statement. There are a number of other techniques that you could use as the beginning of the quarter and end of time stored in a separate folder.

  • How many user accounts is permitted in windows 7 Home Premium

    Hi, I finally bought Windows 7 Home Premium and had a number of questions below:

    (1) how many users can use Windows 7 Home Premium?
    (2) can I use my (created during the installation of windows) default Administrator account and the guest account?
    (3) can I use my default Administrator account and leave someone else to use the guest account?
    (4) can I create another administrator account and delete my old account administrator?
    (5) can I as administrator (single user) to use more than one user account on my computer?

    Yours,
    MMK.

    (1) don't know (or believe) that there is a numerical limit on the number of accounts no matter who would be worried about using "Home Premium".
    FOR THIS I NEED SOME EXPLANATIONS!

    (2) Yes.  Or advised by some, while first by most.
    For comments, I understand that this account represents a risk factor. But why the account (by default) is not advisable?

    Yours,
    MMK

    (1) do you intend to have thousands of users on the computer Windows 7 Home Premium?  Then you have no worries.  Well, more accurately - it depends on the resources you have.  If you have the hard drive space, you can continue to create users in general.

    It is Home Premium and not professional, enterprise or ultimate edition - it is unlikely, it is used in a domain environment where user accounts are supposed to be more than an environment domestic.  Although you can use it in a business environment - is obviously not a big company.

    (2) - for the most part - you need multiple administrative level accounts; reasons for backup.  The built-in function is one that stays around.  Use it every day and for everything which is not only as imprudent as the use of any other administrative level account-, but it adds to the danger, because it is one you are not easy to get rid of.

    My advice is for you to create at least one additional administrative level account and make sure that the passwords for all the administrative accounts (different passwords for each account) is 15 + characters with at least one of the three following types of characters: uppercase letters, lowercase letters, number, and symbol.  Then create standard accounts for each normal computer user and don't give the administrative password to those entrust you the powers he gives them.  No need to start as an administrative level account for most (if not all) - just creative use of RUN AS ADMINISTRATOR.

  • R28 will not support iPad 1 - how many users use?

    I'm very upset about Adobe now. New version R28 is matter for support in iOS 5 and therefore iPad 1. It's ok, it's just evolution. But we don't know how many users now use iPad 1. Adobe these data, but do not share them with us, users of the professional version.

    So we have no idea, how the visitors lose us, when we kill support in iOS 5.

    Martin

    5-10% figure seems accurate to a large extent. I heard that about 8% of folio downloads are on iOS 5 iPads, and about two thirds of these devices are devices of the iPad 1. In other words, some users of the iPad 2 is expected to update their OS device to update the application.

    Felipe, I must correct you one thing. New features like geolocation require not necessarily the newest version of the application to work. In particular, the geolocation feature requires v27 apps but only v25 or folios later. When v28 releases, you can build an application v28 and publish v27 folios, for example, to take advantage of the latest v28. All existing customer iPad 1 can always download the folio v27 (assuming they have a v27 app) without update to the app v28. When iOS 7 releases, users will be able to take advantage of the new iOS 7 functions, such as the slight user interface, AirDrop. We will provide more information about the v28/iOS version 7 later.

    If you're concerned by allowing to the existing iPad 1 clients to continue to be able to download new content, update of an application of v27... and continue to publish v27 folios is an option. As I said, you can then update your versions of Viewer (v28, v29, v30, etc.) to take advantage of the new features of the app and continue to publish your iPad users v27 folios 1 is available for download. At some point, you'll probably want to update the version of folio as well as the version of the Viewer, but he can't do that right now.
