  • HT201343 My MBP is Early 2011 but dunno why cant use mirroring with apple TV, the icon cannot be found

    My MBP is Early 2011 but dunno why cant use mirroring with apple TV, the icon cannot be found. So cannot use mirroring.
    I have follow trouble shooting , they recommend to go system preference -> display , thus can find out the mirroring icon if no mean it doesnt support. But according to the web, Early 2011 MBP should be able to use, dunno why.

    Just realise I havent updated my OS to mountain lion and this is the reason why I cannot use mirroring before ^^
    Thanks all

  • Different results using View with union all in 11R1 compared to 10R2

    Hello,
    I have the following situation:
    In Oracle 10R2 I defined a view which looks like this
    create view test_view
    as
    select 'field1;field2;field3' field from dual
    union all
    select field
    from (
    select tfield1||';'||tfield2||';'||tfield3 field
    from table1
    order by tfield1,tfield2,tfield3
    The idea is, my first line contains a header information an then the data in the required sorting order.
    So, in 10R2, when I export the view with select field from test_view, I get the result as expected, which means, the header from the part with the dual was in the first line and after that, the data in the required sort order.
    Now, in 11.1.0.7, it is completely different, because the row of the dual is somewhere in my result set. But if I send the sql instead of the view, I get the expected result as in 10R2.
    I have no idea why this is the case now, because in 10R2 this was working permanently as expected. When I look at the execution plan, I see, that he starts parallelisation, which is ok, but the difference is, that in this parallelisation the select from dual is included and in 10R2 he first make the line from the dual and then the parallelisation with the data. It's not clear to me, that if I send the sql to the database I see the required result, but if i define the view as mentioned, and start a select field from view, I get now get the different sorting, because of the parallelisation, where the optimizer he changes his behavior comparing the both database versions. So my question ist, how can I change this behavior to get the same behavior as in release 10R2.
    Best regards
    Rainer

    Hello,
    thank you for your sample, I see your idea for my sorting purpose.
    I want to look at the following point:
    I create the table, as you described. The table has the degree and instances 1. Now I deefine the following view:
    create view view_test
    as
    select 'field1;field2;field3' field
    from dual
    union all
    select tfield1 || ';' || tfield2 || ';' || tfield3 field
    from (select * from table1 order by tfield1,tfield2).
    This is the way I used it in 10 R2.
    Now, the SQL select field from view_test delivers the expected result:
    field1;field2;field3
    a;b;c
    d;e;f
    So far so good. But now, I changed the degree of the table1 (alter table table1 parallel (degree 4 instances 1);).
    The result looks like that:
    a;b;c
    field1;field2;field3
    d;e;f
    So, the parallelisation of my object seems to be the reason for the, in my eyes, "wrong" sort order. In 10R2 I used this degree and instance values for my table and defined a view and it was working fine. Now, after our migration, I had this "trouble". For me it seems, that the optimizer made some changes, or mabe this is a bug, who knows ?
    I also tried, to change the nls_comp, and set the undocumented parameters as described in the Metalink note 7497640.8, but with no effect of my result set.
    Best regards

  • XMLType view WITH OBJECT ID

    Hallo,
    Can anyone explain me the purpose of the "with object id"-clause in an xmltype view in detail? According to the documentation the oid should uniquely identify each row in the view. But there is no error message if I choose an elements that occurs in multiple rows of the view. It is possible to choose an unavailable path to an ele-ment without any error messages, too ....
    Is it possible to choose a String as the OID too? I always get an "ORA-22973: size of object identifier exceeds maximum size allowed".
    thanxs,
    Vanessa

    object-id should provide a unqiue identifier. It's needed if you want to generate a ref() to the rows in the view (for instance if you want to folder the rows as documents in the xml db repository). It can also be used during query optimization

  • Using REF with object table in SQL Developer

    When i create object tables and fill them with data, then in SQL Developer de REF value isn't displayed.
    I did the following:
    CREATE TYPE adres_type AS OBJECT
    (straat VARCHAR2(20)
    ,nummer VARCHAR2(10)
    ,postcode VARCHAR2(6)
    ,plaats VARCHAR2(50));
    CREATE TABLE adressen of adres_type;
    CREATE TYPE locatie_type AS OBJECT
    (nr NUMBER
    ,naam VARCHAR2(20)
    ,adres REF adres_type);
    CREATE TABLE locaties OF locatie_type;
    CREATE TABLE locaties OF locatie_type
    (SCOPE FOR (adres) IS adressen);
    insert into adressen values (adres_type('Arnhemsestraatweg', '33','6881ND','Velp'));
    insert into locaties values (1,'Directie', (select ref (a) from adressen a where a.plaats = 'Velp'))
    Then in SQL Developer de REF(A) column is empty, while in SQL*Plus it displays the REF value:
    In SQL Developer: SELECT a.*, REF(a) FROM adressen a;
    STRAAT NUMMER POSTCODE PLAATS REF(A)
    Arnhemsestraatweg 33 6881ND Velp
    In SQLPLUS: SELECT a.*, REF(a) FROM adressen a;
    STRAAT NUMMER POSTCODE PLAATS REF(A)
    Arnhemsestraatweg 33 6881ND Velp 0000280209C70341FBB96B4F77813B27B50E53BB4332382E22ADD64AD9B755F651D416B6DA010134
    Is this a bug or is there another reason why the ID doesnt display in SQL Developer.
    (this didnt work in all the previous SQL Developer releases and still not in de 2.1 E.A. version)

  • Discoverer 4i Plus returns no data when using views with db link references

    I am using Discoverer 41 Plus to view reports online.
    When I create a worksheet based on a view, that only references local tables, everything is OK and Disco plus shows the output OK.
    When I create a worksheet based on a view, that references a Database link, Disco plus gives me an "Query caused no data to be returned" error.
    Is this to be expected from Discoverer Plus?
    Thanks - Sue.

    I'm wondering if this has anything to do with the default position (and default aggregate) for the EUL folder item? I can see that some of the folders have number type items with default position 'Data Point' and others have these with default position of 'Top or Side'. I'm totally stabbing around in the dark here; looking at EUL folders which exhibit the problem and those which don't.
    I've tried changing one field to 'Data Point' and it hasn't helped. Will try changing the join items now I think.
    If anyone has any comments, would be v. grateful as I'm looking at dropping folders which have quite a bit of code around them and trying to re-create them exactly, which is a risky and horrible solution.

  • Inconsistent SQL results when using View with UNION-ALL and table function

    Can any of you please execute the below scripts and check the output. In the table type variable, I am adding 4 distinct object ids, where as in the result, I get only the row pertaining to last id in the table type variable. Same row is returned 4 times (4= number of values in the table type).
    This scenario is occurring in our product with a SQL with exactly same pattern. I could simulate the same issue with the sample script I have provided.

  • ORA13226 when using view with geometry created using sdo_util.simplify

    I have a polygon table (and spatial index) using Ora11.1 that i can query such as:
    Select ID From MyTable A where (MDSYS.SDO_RELATE(A.GEOMETRY, SDO_GEOMETRY(2003, 8307, NULL, SDO_ELEM_INFO_ARRAY(1, 1003, 3), SDO_ORDINATE_ARRAY(73.091805, 18.312310, 72.250051, 19.076872)), 'mask=INSIDE+COVEREDBY+EQUAL querytype=window') = 'TRUE');
    This query returns 2 rows. I have created a view:
    create or replace view v_MyTable as
    select id, sdo_util.simplify(geometry,20,2) as s_geometry
    from MyTable;
    The subsequent query returns ORA13226
    Select ID From v_MyTable A where (MDSYS.SDO_RELATE(A.S_GEOMETRY, SDO_GEOMETRY(2003, 8307, NULL, SDO_ELEM_INFO_ARRAY(1, 1003, 3), SDO_ORDINATE_ARRAY(73.091805, 18.312310, 72.250051, 19.076872)), 'mask=INSIDE+COVEREDBY+EQUAL querytype=window') = 'TRUE');
    If I create a view which does not use the simplify function the query works.

    tcbalent,
    This is correct behaviour if you are trying the query the view:
    Select ID
      From V_MyTable A
    where (MDSYS.SDO_RELATE(A.GEOMETRY, SDO_GEOMETRY(2003, 8307, NULL, SDO_ELEM_INFO_ARRAY(1, 1003, 3), SDO_ORDINATE_ARRAY(73.091805, 18.312310, 72.250051, 19.076872)), 'mask=INSIDE+COVEREDBY+EQUAL querytype=window') = 'TRUE');This is because the A.GEOMETRY is not the geometry in the original table (MyTable) but a programmatically
    constructed geometry on the fly which is not indexed.
    You can fix this with a function based index as follows (NOTE: This uses my own test data that is projected and not geodetic):
    DROP  table myTable;
    create table myTable
    as
    select rownum as Id, geom as geometry
    from  projpoly2d
    where polytype NOT IN ('COMPOUNDOUTERSHELL','VERTEXWITHARCNOHOLE');
    delete from user_sdo_geom_metadata where table_name = 'MYTABLE' and column_name = 'GEOMETRY'; commit;
    insert into user_sdo_geom_metadata(table_name, column_name,diminfo,srid)
    select 'MYTABLE','GEOMETRY',diminfo,srid
      from user_sdo_geom_metadata
    where table_name = 'PROJPOLY2D'
       and column_name = 'GEOM';
    commit;
    create or replace view v_MyTable
    as
    select id, sdo_util.simplify(geometry,20,2) as S_geometry
    from MyTable;

    select 'MYTABLE','MDSYS.SDO_UTIL.SIMPLIFY(GEOMETRY,20,2)',diminfo,srid
      from user_sdo_geom_metadata
    where table_name = 'MYTABLE' and column_name = 'GEOMETRY';
    commit;
    select * from user_sdo_geom_metadata;
    -- Now create index
    drop   index MyTable_sgeometry_spdx;

  • Using Views with Dimensions

    OWB Client: 10.2.0.1.31 -- OWB Repository 10.2.0.1.0
    I have an unbalanced Product Dimension that is populated by 3 tables as it has 3 levels (All Products, Products, Sub-Products). Departments within our company have different hierarchies and groupings of our products and require different Views from one another in our reporting. I can build 25 different Product Dimensions and the 51 different product tables to support these dimensions but I'd like to stick to just 3. When I try to create Views over the 3 product tables I get: "ORA-01702 a view is not appropriate here".
    Oddly enough, you can build a Dimension from Views in AWM.
    Anyone have any ideas?

  • Materialized view with build deferred

    Hello,
    Do you have some idea why CREATE MATERIALIZED VIEW with BUILD DEFERRED option takes a lot of time? It's running 1 hour and not finish (Oracle 9.2).
    CREATE MATERIALIZED VIEW mv_users
    BUILD DEFERRED

    Users table has 10 millions records.
    Edited by: user12111171 on 2011-09-16 13:28

    If the Job Queue is not enabled,  the CREATE cannot auto-schedule the refresh.  You need to have JOB_QUEUE_PROCESSES set to 1 or greater.
    It would seem that when you say "I have created job to refresh the materialized view everyday using dbms_refresh.refresh"  you haven't created a job using DBMS_JOB.SUBMIT   (which is what the CREATE MATERIALIZED VIEW would do "behind the scenes" --- you can then query DBA_JOBS or USER_JOBS to see the auto-submitted job).

    I�m implementing a databaseapplication with J2EE and Sun AppServer 8.1. Now I actually don�t want to use the database-tables directly. Instead I want to use views, because then the structure of the underlying table doesn�t matter. Only the view needs to be modified.
    Is it possible to use Entitybeans with views? Or is it only possible to use EJBs with tables?
    If it is possible please be so kind to give an example or explain how. I tried the capture-schema - Approach but there are no views in the capturefile. Please help!
    Thank you!
    Gregor

    You should be able to use views with EJBs, but as you correctly realized, you need to get them into your dbschema file first. Try specifying the view names as parameters to the table arguments in the capture schema tool, or try the UI for schema capture in NetBeans or Studio.

  • TreeSet with Objects

    Hello,
    I am doing something silly, and I can't figure it out.
    I want to use TreeSet with Objects, not strings, the code below throws a class cast exception:
    Exception in thread "main" java.lang.ClassCastException: com.generatescape.newtreemodel.CanalNode
         at java.util.TreeMap.compare(Unknown Source)
         at java.util.TreeMap.put(Unknown Source)
         at java.util.TreeSet.add(Unknown Source)
         at com.generatescape.testscape.JustMain.main(JustMain.java:35)
        TreeSet ts = new TreeSet();
        CanalNode cn1 = new CanalNode("X",0);
        CanalNode cn2 = new CanalNode("a",0);
        ts.add(cn1);
        ts.add(cn2);The equals method of canalnode is defined. Do I need to define another method, for example compare?
    thanx
    susie

    thanksyou're welcome - though part of that might need some clarification - I meant that if you don't supply a comparator of your own in the constructor of your TreeSet then you need to make sure that everything you put in there implements the Comparable interface (if you do supply your own Comparator then you'll know what it requires).
    Hope that helped (and didn't just muddy the waters more)

  • [svn:bz-trunk] 5137: Fix failing security tests on BlazeDS/ trunk by using a remote object to invalidate the FlexSession at the end of each test method which should cause each test method to run with a new /clean session.

    Fix failing security tests on BlazeDS/trunk by using a remote object to invalidate the FlexSession at the end of each test method which should cause each test method to run with a new/clean session. It looks like some test methods were leaving some things in a bad state which was causing the next test that ran to fail. These may be legitimate bugs/issues so we should investigate further to see what sequence of events gets things into a bad state but for these tests we want all of the test methods to run in isolation.

    In general theory, one now has the Edit button for their posts, until someone/anyone Replies to it. I've had Edit available for weeks, as opposed to the old forum's ~ 30 mins.
    That, however, is in theory. I've posted, and immediately seen something that needed editing, only to find NO Replies, yet the Edit button is no longer available, only seconds later. Still, in that same thread, I'd have the Edit button from older posts, to which there had also been no Replies even after several days/weeks. Found one that had to be over a month old, and Edit was still there.
    Do not know the why/how of this behavior. At first, I thought that maybe there WAS a Reply, that "ate" my Edit button, but had not Refreshed on my screen. Refresh still showed no Replies, just no Edit either. In those cases, I just Reply and mention the [Edit].
    Also, it seems that the buttons get very scrambled at times, and Refresh does not always clear that up. I end up clicking where I "think" the right button should be and hope for the best. Seems that when the buttons do bunch up they can appear at random around the page, often three atop one another, and maybe one way the heck out in left-field.
    While I'm on a role, it would be nice to be able to switch between Flattened and Threaded Views on the fly. Each has a use, and having to go to Options and then come back down to the thread is a very slow process. Jive is probably incapable of this, but I can dream.
