• I'm having a problem on line when someone else uses the same router, error message: there is an IP address conflict

  Original title: I'm having a problem online when someone else uses the same router I have...

  I bought a new laptop with windows 7 premium. I connect to the internet through an external modem dsl and a wireless belkin n router. My daughter has an Android and uses the same connection... The problem is that we cannot not be online at the same time... If shes online using his android I can't connect using the laptop and if Im online using the laptop, she can't get online using his android... The error message indicates that there is a conflict of IP address... And sometimes says that there is a dns error... How can I fix this problem so that we can surf the net using the same connection?

  Hello

  Router is the gateway to the Internet, and it assigns the IP address for different devices. With the error message, you have so many IP address conflict, it seems that the IP address is not assigned correctly on the router.

  I suggest that you turn off all devices, reset the router and turn on the router. Once that is done turn the whole one and try to connect to the Internet.

  For assistance on this, you can contact your router manufacturer or Internet service provider.

  Hope the information is useful.

• Performance problem when a direct IO option is selected

  Hello Experts,
  
  One of my clients has a performance problem when a direct IO option is selected. Reports that there was increase in the memory usage of storage Direct to e/s is selected compared to the option of buffering of i/o.
  
  There are two applications on the server of type OSB. When using IO buffer warnings, has experienced a high level of read and write I / O direct i/o reduced the read and write I / O, but greatly increases the memory usage.
  
  Other information-
  
  (a) Details of the environment
  
  HSS - 9.3.1.0.45, AA - 9.3.1.0.0.135, Essbase - 9.3.1.2.00 (64-bit)
  OS: Microsoft Windows x 64 (64-bit) 2003 R2
  
  (b) what is the use of memory when it is buffered for i/o and direct i/o is used? What running of calculations, restructuring of the database and the database queries? These processes take a lot of time for execution?
  
  Application 1: 700 MB buffered, 5 GB live
  Application 2: Buffering 600 MB to 1.5 GB, 2 GB Direct
  Calculation time can increase from 15 minutes to 4 hours. Even with the restructuring.
  
  
  (c) what is the current database cache; Cache data files and cache Index values?
  
  Application 1: Buffering (index 80 MB, 400 MB of data), Direct (Index 120Mo;) 4 GB data file, given 480 MB).
  Application 2: Buffering (index 100MB, 300 MB of data), Direct (Index of 700 MB, 1.5 GB, 300 MB of data from data file)
  
  
  (d) what is the total size of the files ess0000x.pag and ess0000x.ind files?
  
  Application 1: Page 20 GB, 1.7 GB of the Index file.
  Application 2: Page 3 GB, index of 700 MB.
  
  Any suggestions on how to improve performance when direct i/o is enabled? All performance records in above scenario would be a great help.
  
  Thanks in advance.
  
  
  
  Kind regards
  Sudhir

  This post understanding buffered of e/s and e/s direct may be of some use to you.

• Performance problem on the SQL query that does not use the primary key index

  Hello!
  
  I have some performance issues on a single SQL query (Oracle 10 g).
  I could solve the problem by using the INDEX indicator, but I would like to know WHY this is happening.
  
  * Tables *.
  create table jobs)
  ID number (5) not null,
  name varchar2 (100),
  primary key constraint Job_PK (id)
  )
  /
  -Record count: 298

  integer ID not null,
  id_job integer not null,
  id_comp integer not null,
  primary key constraint JobComp_PK (id),
  unique key constraint JobComp_UK (id_job, id_comp),
  Constraint JobComp_FK_Job foreign key (id_job) refers to Job (id),
  Constraint JobComp_FK_Comp foreign key (id_comp) makes reference Comp (id)
  )

  /
  create index JobComp_IX_Job on JobComp (Cod_Job)
  /
  -Record count: 6431
  
  * Ask *.
  
  When I run this query, the execution plan shows the index using (JobComp_PK and JobComp_IX_Comp).
  No problem.
  
  Select JobComp.*
  of JobComp
  Join jobs
  on Job.id = JobComp.id_job
  where JobComp.id_comp = 134
  /
  -runs in 0.20 sec
  
  But when I add the field 'name' of the work table the plan uses full access table to the table of work
  
  Select JobComp.*, Job.name
  of JobComp
  Join jobs
  on Job.id = JobComp.id_job
  where JobComp.id_comp = 134
  /
  -runs in the 2.70 dry
  
  With the help of the index
  
  Select / * + INDEX (Job Job_PK) * /.
  JobComp.*, Job.name
  of JobComp
  Join jobs
  on Job.id = JobComp.id_job
  where JobComp.id_comp = 134
  /
  -runs in 0.20 sec
  
  * Doubt *.
  
  This behavior is correct?
  
  PS. : I tried to recalculate the statistics, but nothing changes:
  
  analyze the job calculation table statistics.
  /
  change the statistical calculation of index Job_PK reconstruction;
  /
  Start
  dbms_utility.analyze_schema (sys_context ('userenv', 'current_schema'), 'CALCULATE');
  end;
  /

  Hello.
  I'm sorry for the plan unformatted.
  The execution time of the querys "without field name' and 'with the field name with suspicion" are equal.
  He has no problem caching, because I get the plans of the sequence different from the querys and repeated the performance. The result is always the same.

  I don't think that there is no problem with oracle crossing LOOP IMBRIQUEE to the HASH JOIN when you include the field name and this should be the expected behavior. But it seems that your WORKING table has a degree of parallelism set against what is causing the query to run in parallel (as JOB table is now available with full table scan, instead of indexed access earlier). It could be that the parallel execution is contributor to extra Runtime.
  (a) do you know why the degree of parallelism on the WORK table has been defined? Do you need it?

  You can see if the following query provides a better response time?

  select /*+ NOPARALLEL(JOB) */ JobComp.*, Job.Name
    from JobComp
    join Job
      on Job.id = JobComp.id_job
   where JobComp.id_comp = 134

• Having a problem with artifacts when using Dip to black transition

  I use Adobe first Pro CC on a Dell XPS 8900 with a NVIDIA® GeForce® GTX 745 4 GB of DDR3 memory. Both in the Editor (with all the rendering) and the final video (which I tried to export in several ways), I get artifacts when using the two Dip to black and chained transitions. I did check the sequence settings to match the original film, as I originally had two cameras (ARRI and XDCAM) images. I get the problem on two types of sequences. I tried to convert the original film in .mp4 using a HD video converter and then re-import it. The problem remains. Then I tried to download sequences of archives on the Adobe site and imported. And I still have the problem. I think that it has something to do with my computer as before to get the XPS 8900 I had used an older Dell model (without graphics acceleration or upgrade) and had not not this problem. You can see artifacts in the video below. Strangely, I don't see any artifacts when I used transitions on the titles of lower third or in transitions from outset between title sequences. It is only when transitions are used on real images (and, again, I tried to use other types of sequences and had the same problem). Any thoughts on how to solve this problem would be greatly appreciated.

  I am simply not see something weird.  The transition is quite fast, however.

  Give that DNxHD export/upload to try.  See if you like better.

• Using Adobe Presenter will not solve the problem of police when I use Acrobat Connect Pro?

  So my fonts in my PowerPoint presentation are not preserved when I use Acrobat Connect Pro (as it is not one of the Adobe fonts). I saw that a member of staff said that thanks to Adobe Presenter it should solve this problem, so if I buy Adobe Presenter and use it on my presentation it will preserve my fonts and also my animations/transitions, etc? Thanks in advance

  It should be. The problem is that when you load a PPT (X) at Adobe Connect it converts to a Presenter presentation. However, it can use only the fonts on the server, which is the basic MS fonts. Publishing locally with the presenter should allow you to use the fonts you have on your computer, so this issue. Your animations and transitions must also be preserved, but you will have your animations sur-Cliquer for control when they are placed in Presenter.

• Problem with the selection list dynamic LOV using bind variables

  I have the following SQL to fill a selection list:
  
  Select d, ch from
  (
  Select ft. FAMT_NAME d, pi. R FAM_ID_T of FAMILY_TRA ft
  Join the ck list
  on ck.family = ft.famt_name and ck.newseq in (: NEWSEQ_QUERY_SQL)
  )
  
  Where NEWSEQ_QUERY_SQL is a part of the application that is defined by a calculation of page and essentially returns a list of values NEWSEQ based on some parameters of the user query. For example:
  
  Select distinct (ck.newseq) in the ck list where rownum < 20
  
  The query above works fine with SQL Developer and returns two columns needed (display_value, return_value)
  
  However, it returns no line, when it is used to fill the LOV to a selection list.
  
  If I replace the: NEWSEQ_QUERY_SQL with a list of NEWSEQ hard-coded, it works:
  
  Select d, ch from to)
  Select ft. FAMT_NAME d, pi. FAM_ID_T r
  of FAMILY_TRA ft join checklist ck on (ck.family = ft.famt_name and ck.newseq in ('K0242900', 'K0217200'))
  ) ;
  
  I can even replace: NEWSEQ_QUERY_SQL with hard-coded SQL and it works:
  
  Select d, ch from
  (
  Select ft. FAMT_NAME d, pi. R FAM_ID_T of FAMILY_TRA ft
  Join the ck list
  on (ck.family = ft.famt_name and ck.newseq in (select ck.newseq from the list ck where rownum < 20))
  )
  
  But if there is a connection variable (: NEWSEQ_QUERY_SQL), it doesn't.
  
  Selection lists are driving me crazy! They seem incredibly capricious.

  Hello:

  You cannot link a "sql statement" that bind the value you're trying to do.
  P2_FAMILY_LIST must be the SQL statement you executed for the LOV. Something like

  select d, r from
  (
  select ft.FAMT_NAME d, ft.FAM_ID_T r from FAMILY_TRA ft
  join checklist ck
  on (ck.family = ft.famt_name and ck.newseq in (select ck.newseq from checklist ck where rownum < 20))

• [ADF, JDev12.1.3] When you rename problems see criteria and link vars used in VO

  Hallo,

  1)

  I changed the name of a view VO criterion, but I'm not able to buld the project.

  Error: myapp.model.vo.MyVO: could not find the referenced object. Object =VC_OLD_NAME Owner = myapp.model.vo.MyVO

  But if I look everywhere in the application I'm not VC_OLD_NAME.

  How can I solve this problem?

  When you rename a VC, JDev auto updates all references to this VC in the application? Or I don't have to worry about it?

  2)

  I renamed a binding var defined for a VO where clause.

  JDev seems to auto update all references to this var binding, but the strange thing is that, in the original Version, the old name is still present (he doesn't).

  Why?

  3)

  Perhaps in the future I would better take not to rename this kind of objects?

  Thank you

  Federico

  1)

  JDev sometimes has problems with refactoring.

  Maybe you can try to close jdev and remove .data folder in your project.

  2)

  Because there is no exact reference to link var if you need to change this manually.

  3)

  Perhaps in the future the jdev will have less bugs
