How application server will take more database connection than specified

Hi,
       While configure the datasource we have specification's/properties for
        1)Initial Connection  (for ex. 1)
        2)Maximum Connection(for ex. 120)
        But we donot know how the SAP Server will take the connection after it reached to maximum connection, There is not propery which tell us to to create new connection.
        Can anyone tell me the process to increment the connection's or how the server behave after it will reach to maximum connection. 
Thanks,
Nitin Uikey

SQL server cannot accommodate 50k update statements simultaneously from 50k sessions. As others have stated, the physical active session limit of the platform is ~32k, and if you genuinely want that out of the box with load balancing on a single db at that
kind of scale then sql server 2008 r2 is the wrong platform.
For what it's worth, Minimum memory overhead per connection will help you work out what your minimum memory requirements are. Note that it's variable dependent
upon the network packet size, which is partially a configuration question, partly one of instruction (byte size of actual db interactions) and finally the size of the actual workload being generated by the session.
Number of processors, and indeed what their capabilities are, that's entirely up to you. To facilitate such a high number of connections concurrently in all honesty I think your network stack is a bigger concern. There is no single golden configuration
for SQL Server, certainly not something that could win a pub quiz with the details provided. While it would be possible to design a theoretical configuration on paper without resorting to building the tin, I can imagine the numbers you come up with might be
a little difficult to build. Just ask Amazon!

  • How can I reuse the BC4J database connection?

    How can I reuse the BC4J database connection?
    I want to use the application module connection without opening another in a custom code. At this level I can’t access de ADF code, that’s why I can’t get the DBConnection from the application module.
    Now, I have a “data-sources.xml” in my project and the application module is configured to access the database from this xml file.

    I found the solution in other Forum. I worked ok.
    Here the code:
    If the Connections-Navigator connection is DBConnection1, the corresponding datasource is jdbc/DBConnection1DS.
    1. Create a JSP page.
    2. In the web.xml of the JSP add
    <resource-ref>
    <res-ref-name>jdbc/DBConnection1DS</res-ref-name>
    <res-type>javax.sql.DataSource</res-type>
    <res-auth>Container</res-auth>
    </resource-ref>
    3. In the JSP page obtain a connection with the datasource.
    InitialContext initialContext = new InitialContext();
    javax.sql.DataSource ds = (javax.sql.DataSource)initialContext.lookup("java:comp/env/jdbc/DBConnection1DS");
    java.sql.Connection conn = ds.getConnection();

    That's not how it works. Once a device (including a computer) is associated with an Apple ID it cannot be switched for 90 days. See this Apple KB article for more information: http://support.apple.com/kb/HT1420.

  • Transaction takes more database time

    Hi friend,
    Today morning one user excute transaction CK40N shows more time at the database level.It impacts on performance of our production system.Now i want to investigate why this transaction takes more database time .
    I want to compare with last 2 months database time taken  by excuting this transaction (CK40N) in the same date and time.
    i tried but i am unable   to get i checked in st03n,stad.
    can  any body can help me how to find out.
    Best Regards,
    kiranchaitanya.
    mine environment:-
    ECC6.0,

    ORACLE-10.0.2.0.2

    Dear Kiranchaitanya
    Regardless of the issue I recommend implementing BR*Tools 7.10 and SAP note [Note 1020260 - Delivery of Oracle statistics|https://service.sap.com/sap/support/notes/1020260] if not yet performed.
    Check the following:
    - Oracle statistics are created daily
    - Oracle system statistics are created quarterly (or after specific interventions)
    - Oracle dictionary statistics are created quarterly (or after specific interventions)
    Check your performance details of Oracle (hit cache ratio and so on) to ensure those are correct in DB02 under Performance Overview.
    To check the transaction in ST03N go into expert mode and on the left pane under "workload" you can compare by week for example
    double-click the week of which you want data. Next go the lower left pane, there you need to db-click on "Standard" under Analysis Views --> Transaction Profile.
    Next find or the list so you have your transaction displayed in the list on the right pane.
    Repeat these steps for other weeks and compare the data.
    Can you tell me how many % of the response time is database time (once you have the transaction on the right pane in ST03N with statistical data, go
    to the third tab there called "parts of response time" and check the %DB Time column) ?
    Kind regards

  • How much time will take applyning SP11 level in ECC6.0

    Hi,
    How much time will take for appying SP11 level in ECC6.0.
    Regards,
    venkat reddy.

    hi,
    Make sure , that you increase the shared memory being utilized by database .
    In oracle we increase the SHARED POOLSIZE , that will reduce the time in ACT_700 .
    There is note which talks about the SHARED_POOL_SIZE , it should be minimum 500 mb , depending upon your total physical RAM and CPU.
    Thanks

  • I have to get my 13 in macbook pro with retina display fixed because of an internal crack and I was wondering how long it will take to repair the screen.

    Since I have to get it fixed and I'm a college student and need my laptop asap, I just want to know how long it will take for my screen to get fixed so I can go back to doing my work.

    No one here could possibly know... you'll have to take your machine to your local Apple Store or an AASP to even begin to get an idea as to how much time it could take to fix your machine.
    I had to wait 10 days just to get fans replaced on my old MacBook Pro...

  • Which of the following will take more memory?

    Hi All,
    which of the following will take more memory:
    ---this-----
    long longval[] = new long[100];
    String strval[100] = new String[100];
    boolean boolval[100] = new boolean[100];
    ---or this-----
    class Data {
    long longval;
    String strval;
    boolean boolval;
    Data data = new Data[100];
    I heard objects will take up more memory than default datatypes. I'm looking for speed and memory optimization, so even the slightest of memory saving will matter.

    Hi,
    the first one needs less memory, I guess - beside the point, that the second one has 100 additional references, is the fact, that allocation of memory on modern machines is not a continous one - new data blocks are arranged so, that they start on even addresses (it's a performance issue) often clustered in multiples of 16, 32 or 64. So if you allocate a lot of single objects, the average loss of memory with each object is 8,16 or 32 Bytes (half the cluster size).
    The first one allocates 3 compact data blocks (arrays) - so 3 times the additional loss of memory takes place. The second one allocates 101 blocks (100 objects + 1 array), and so 101 times the additional loss of memory takes place.

  • The application requires more database privileges than you have currently

    Hi,
    on 10g R2, no one can login to DB Control grid (not sys, not sysman nor system ). We get the following :
    The application requires more database privileges than you have currently been granted. Click on Help to get more version specific information.
    We are sure of password.
    I saw and applied the metalink notes 330682.1 and 363065.1 that says :
    grant SELECT_CATALOG_ROLE to user;
    grant select any dictionary to <user>;
    but no result.
    Any help ?
    Thank you.

    1. What operating system.
    2. What version of Oracle (10gR2 is a marketing label not a version number ... provide all decimal places)
    3. What are the values of the environment variables ORACLE_HOME and ORACLE_SID?

  • HT3302 How much will be charged for replacing a cracked screen for iPhone 5? How long it will take for repair?

    Hi Folks,
    I am a visitor and had my iPhone 5 cracked the front screen today, I just want to know how long it will take for repair if I send to Apple USA, and the charge for the replacement of the cracked screen.
    Thanks for your advice in advance, I am currently in LA and will put into LA Apple Store asap.

    Warranty and support are only valid in the country of origin.
    If the device was not purchased in the US, an Apple store in the US will not touch it.

    how long it will take for apple to verify my info to get the new software for free?
    i have submit my request since 6 hours, is that normal??

    from what i hear, it takes a minimum of 72 hours before you hear back from Apple.
    but because there are a lot of people are wanting to get their free upgrades, it might take even longer now.
    good luck - just be a little patient and your turn will come soon....

  • How long it will take us to do BW-ODB certification normally?

    How long it will take us to do BW-ODB certification normally?
    SAP Integration & Certification : Integration Scenarios - Business Intelligence (BW-ODB)
    thanks

    The certification test itself normally takes about half a day. However before that certainly some paperwork has to be done.
    So please first go to <a href="http://www.sap.com/partners/apply">www.sap.com/partners/apply</a> and apply for the certification. We will then issue a contract and once this is mutually signed, we can do the test. This whole process can be done in about 3-4 weeks.
