How to get statistics (or precise data) about cpu speed and RAM

My problem is I want to determine the CPU speed of the computer is running the applet.
I know there's no way to obtain in a simply (and standar) way this property, so I've thinked about generating statistic methods for do it (something like executing a loop a defined iterations)
My doubt is what to put inside this loop, beacuse I would like to know just not CPU speed (or satistics about it), I need also free RAM statistics, so I've thinked there would be some specific java instructions to give a relationship of these data I need.
My question is if someone has done (or has thinked about) this kind of classes before me, and can tell me what is the best way to make the same.

    Below is an example of the scenario..
    CREATE OR REPLACE PACKAGE chck IS
    PROCEDURE getdata(dept_no IN VARCHAR2,oc_result_cursor OUT sys_REFCURSOR);
    TYPE get_rec is record (ename varchar2(20),
    eno number(12));
    TYPE t_recs IS TABLE OF get_rec INDEX BY BINARY_INTEGER;
    emp_tab t_recs;
    END chck;
    CREATE OR REPLACE PACKAGE BODY chck AS
    PROCEDURE getdata(dept_no IN VARCHAR2,oc_result_cursor OUT sys_REFCURSOR)
    is
    BEGIN
    select ename, eno
    bulk collect into emp_tab
    from emp;
    open oc_result_cursor for select * from table(emp_tab); -- I believe something is wrong here ....
    END;
    END chck;
    the above package is giving me an error:

    once i get the data into a plsql table, how to get this plsql table data into the cursor?There is no such thing as a PL/SQL table - it is an array.
    It is nothing at all like a table. It cannot be indexed, partitioned, cluster, etc. It does not exist in the SQL engine as an object that can be referenced. It resides in expensive PGA memory and needs to be copied (lock, stock and barrel) to the SQL engine as a bind variable.
    It is an extremely primitive structure - and should never be confused as being just like a table.
    Its use in SQL statements is also an exception to the rule. Sound and valid technical reasons need to justify why one want to push a PL/SQL array to the SQL engine to run SELECT 's against it.

  • How to get the user entered data?

    Hi all,
    I have created an HTMLB DynPage component.
    In That i have created my input screen with textboxes using response.write method.
    i have added one onConfirm event on which the data whould validate.
    so onConfirm method im trying to get the data with request.getParameter method which returns null...
    how to do...how to get the user entered data to do my validations...can anyone plz advice.
    Thanks,
    Viswes

    Hi
    inputfield or textbox component entered directly using response.write(...) are not htmlb , but html.
    to create portal input field (ie HTMLB), you should do something like
    this in the doProcessBeforeOutput member function
    InputField field1 = new InputField("Id1");
    field1.setSize(8); // 8 characters
    this.getForm().addComponent(field1);
    and in doProcessAfterInput member function
    InputField field1 =
    (InputField) this.getComponentByName("Id1");
    you can then manipulate the content of the field.
    Hope this help,
    Guillaume

    I tried to use
    IUMPrincipal RefGroup = WPUMFactory.getGroupFactory().getGroup(groupName);

    Ok,
    try this:
    com.sapportals.portal.security.usermanagement.IGroupFactory ep5GroupFactory = userManagementService.getGroupFactory();
    IGroupFactory groupFactory = UMFactory.getGroupFactory();
    com.sap.security.api.IGroup group = groupFactory.getGroupByUniqueName(groupName);
    IUMPrincipal ep5Principal = ep5GroupFactory.getEP5Group(group);
    This should do the trick,
    Romano
    PS: and thanks for the stars!

    Could you please let me know how to get an email when data got inserted into table by using sql/plsql
    Well that seems pretty straightforward - write some pl/sql to send you an email when that pl/sql inserts data into a table.
    See this Oracle-base article for an example of sending mail.

    Post what you have tried so far. What part of what you have tried doesn't seem to be working?

    Hi bluegrandpanash,
    Thanks for visiting Apple Support Communities.
    If you backed up your iPhone to iCloud before updating the software, first try the steps under "Restore from an iCloud backup" in this article to recover your data:

  • I am not able to access the "Settings" on my iPad 3. I just get a gray screen for about 30 seconds and then the app shuts down. I am also unable to access the App store, iTunes, or any app requiring an internet connection. Any thoughts?

    I am not able to access the "Settings" on my iPad 3. I just get a gray screen for about 30 seconds and then the app shuts down. I am also unable to access the App store, iTunes, or any app requiring an internet connection. Any thoughts?

    First, try a system reset.  It cures many ills and it's quick, easy and harmless...
    Hold down the on/off switch and the Home button simultaneously until the screen blacks out or you see the Apple logo.  Ignore the "Slide to power off" text if it appears.  You will not lose any apps, data, music, movies, settings, etc.
    If the Reset doesn't work, try a Restore.  Note that it's nowhere near as quick as a Reset.  Connect via cable to the computer that you use for sync.  From iTunes, select the iPad/iPod and then select the Summary tab.  Follow directions for Restore and be sure to say "yes" to the backup.  You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod.  Again, say "yes."

    have an ipod and then got the wife an iphone4. all passwords are screwed up. she can not access playstore cuz she doesn't have password. i can not get find any help on how to get or update a password for the ipod. and then get her a separate password for her iphone. we need to save her photos, music, etc to ? icloud and the phone stuff to verizon cloud? so when she gets her new Iphone6 she can have all her "stuff" back on the new phone. hope this makes sense. please offer suggestions here or at [email protected] thanks for your help!

    Oh no! I'm sorry to see there's a lot of confusion here and data shared, x-rayDon. We can definitely work to fix. This happens when two devices share the same Apple ID, so she will need to reset hers. She can do so by assessing this link Apple - My Apple ID. You will need to decide who will keep the account if want separate Apple IDs since purchases cannot be shared unless you do Family Sharing.
