Find the number of connections coming through a listener

Hi,
We have 10 listeners on our database. How to find out at runtime , how many users are accessing through a specific listener.
Is v$dispatcher the view needed to query.
Please guide.
Thanks.

Hi,
But through service name how do i find th specific listener port. I have multiple entries of different ports across my service name in the tns file.
Below is what my TNS entry looks like,
PRODDB =
(DESCRIPTION=
(ADDRESS_LIST=(PROTOCOL=TCP)(HOST = 192.19.100.10) (PORT=1520)))
(ADDRESS_LIST=(PROTOCOL=TCP)(HOST = 192.19.100.10) (PORT=1521)))
(ADDRESS_LIST=(PROTOCOL=TCP)(HOST = 192.19.100.11) (PORT=1522)))
(ADDRESS_LIST=(PROTOCOL=TCP)(HOST = 192.19.100.11) (PORT=1523)))
(ADDRESS_LIST=(PROTOCOL=TCP)(HOST = 192.19.100.11) (PORT=1524)))
(ADDRESS_LIST=(PROTOCOL=TCP)(HOST = 192.19.100.15) (PORT=1530)))
(CONNECT_DATA = SID = PRODDB))
Her for one ip there are more than one ports assigned.
RegardsDo not see tnsnames.ora file,please run lsnrctl status or lsnrctl service from the server then you will see all services which registered on listener.

  • Finding the number of connected components in a graph

    I don't know haow many people have seen this problem posted on c.d.o.m, but here is the essence
    given an equivalence relation, e.g.
    x y
    1 1
    2 2
    2 1
    1 2
    3 3
    find the number of equivalence classes. In this example equivalence classes are {1,2} and {3}.

    The idea: Label all the graph nodes with distinct primes. Find all simple paths in the graph weighted with product of nodes. Find the skyline of all maximal products. Count them.
    Implementation (swithced to boolean vectors instead of primes)
    create table input as (
    select 1 x, 2 y from dual
    union
    select 2, 3 from dual
    union
    select 2, 4 from dual
    union
    select 6, 7 from dual
    union
    select 8, 9 from dual);
    with TC as (
    select connect_by_root(x) x, y
    from (
    select x,y from input
    union
    select y,x from input
    ) connect by nocycle x = prior y
    ), weightedNodes as (
    select node, power(2,rownum-1) code
    from (select x node from input
    union select y node from input )
    select count(distinct code) from (
    select x,y,sum(code) code from (
    select distinct pre.x, pre.y mid, post.y from TC pre, TC post
    where pre.y=post.x
    ), weightedNodes
    where node = mid
    group by x,y
    drop table input;

    Excellent.
    Tested, works as long as you set the ORACLE_SID first ( to change databases )
    ps -ef | grep $ORACLE_SID | grep "LOCAL=NO" | awk '{print $2}' | wc -l
    Thanks!

  • 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 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 do I find the number of contacts in a smart group?

    How do I find the number of contacts in a smart group in Contacts?

    Hi,
    To get the depth using JMS you must create a QueueBrowse and browse the entire queue. Its generally horribly inefficient if you want to do it with any regularity.
    In Hermes I have had to write plugins that open separate connections to providers using their non-JMS APIs or JMX and get that kind of information that way.
    Look at the getDepth() method in this JBoss plugin for an example that uses JMX:
    http://cvs.sourceforge.net/viewcvs.py/hermesjms/Hermes4/src/java/hermes/ext/jbossmq/JBossMQAdmin.java?view=markup
    And here is one for WebSphereMQ that uses one of its many APIs..

  • How to find the number of pending messages in a Queue

    All,
    Is there a way to find the number of pending messages in a given QUEUE to be picked by the queue reader?
    My reader is not picking all the messages as many sent by my writer, i am not sure where they are getting lost? or if the JMS implementation is buffering them and does not flush until it does not have enough to throw out ( which any way does not make sense!!).
    Please help.
    Chandra

    You're right in thinking that the behaviour you describe looks wrong.
    Take a look at the QueueBrowser interface which can be used to inspect a queue. You get one using QueueSession.createBrowser(Queue). The QueueBrowser allows you to scan a queue without consuming the messages. However note that the state of the queue may change while you're observing it through the QueueBrowser so what you see might not always be a 100% accurate representation of the queue at any given time.
    Other things to check:
    - message selectors - are you setting a message selector on your queue receiver which is resulting in not all of the messages 'matching'.
    - expired messages - are you setting a time-to-live on the messages that you publish.
    Hope this helps,

  • Can I find the number of times the recorded meeting has been viewed?

    In Adobe Connect is it possible to find the number of views after a recorded meeting is made public? Under meeting dashboard it keeps track of these views for 30 days but I can not seem to find anywhere under the reports where this information is located.

    If you move the recordings to the Content Library, then you can pull the standard content reports for it, which will tell you number of views.

    Can't locate email content? All of a sudden my email content has disappeared from inside MacMail? The actual emails are coming through but I am unable to view them in the content area! Nothing has been done to have changed this?

    Please read this whole message before doing anything.
    This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
    Step 1
    The purpose of this step is to determine whether the problem is localized to your user account.
    Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
    While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
    Test while logged in as Guest. Same problem?
    After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
    *Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
    Step 2
    The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
    Please take this step regardless of the results of Step 1.
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
    Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
    Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    Test while in safe mode. Same problem?
    After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

  • Need help in finding the number of occurrences of a pattern.

    Hi All,
    I need help in finding the number of occurrences of a pattern in a table's column's data.
    Consider sample data - one row's column from a table:
    "S-S-S-A-S-S-P-S-S-B-S-A-P-S-S-C"
    My requirement is:
    I should get the count of S's which are immediately preceded by A or P.
    for the above data i should get count as 3+2+1=6 (S-S-S-A, S-S-P, S-A)
    The pattern data is stored as VARCHAR2 type.

    I am sure there exists a better way then this one:
    SQL> with dt as
      2  (select 'S-S-S-A-S-S-P-S-S-B-S-A-P-S-S-C' str from dual)
      3  SELECT SUM(Regexp_count(Regexp_substr(str, '(S\-?)+(A|P)+', 1,
      4                                     Regexp_count(str, '(S\-?)+(A|P)+') - (
      5                                                  LEVEL - 1 )), 'S')) len
      6  FROM   dt
      7  CONNECT BY LEVEL <= Regexp_count(str, '(S\-?)+(A|P)+')
      8  /
           LEN
             6

  • Other macs are connecting to the wireless no problem.  mine finds the wireless and connects, but I can't browse the internet at all.

    I am a teacher.  My Macbook has had no problem all year long connecting to the school's wireless until yesterday.  My computer tells me I am connected, but does not let me use the internet at all.
    Things I've tried:
    - Restarting
    - Running Network Diagnostics (I get to the point where it says my internet appears to be working correctly... but it's not)
    - Pinging websites like Google (no success)
    - Checking to see that other people's Macbooks are connecting, no problem (they are)
    - Checking to see if a browser other than Safari works (Firefox does not)
    At home, my computer works fine.  But at school (work), I've got nothing.  Weirder still, in my Mac Mail, I have my Gmail and my school email set up.  The school email (i.e. the local network) is coming through to Mac Mail and working normally, but my Gmail is not working, just like the internet.
    Any thoughts about what to try next?
