• Dynamic creation of the JMS queues

  Hello
  
  I understand that it is possible to define queues (and subjects) in configuration appropriate application jms.xml file. However, I suppose it is also possible to dynamically create JMS queues (i.e. at run time).
  
  Could someone point me in the right direction for more information on how I can achieve this? I used have a Oracle 10 g and intend to use Oracle AS JMS.
  
  Thank you very much

• Insert the dynamic creation of statements

  Hello

  My version of db is: 11g Enterprise edition 11.2.0.3.0

  I am trying to create queries dynamically insert using the code below:

  declare

  v_cl varchar2 (4000);

  v_tn1 varchar2 (30): = 'T1 ';

  v_tn2 varchar2 (30): = 'T2 ';

  v_vl varchar2 (4000);

  v_id number 4: = 900;

  v_il varchar2 (4000);

  v_count number (3): = 1;

  cursor c1 is select column_name from all_tab_columns where table_name = v_tn1 order of column_id.

  cursor c2 is select column_name user_tab_columns where table_name = v_tn2;

  Start

  I'm looping c1

  v_cl: = v_cl | «, » || i.column_name;

  end loop;

  v_cl: = ltrim (v_cl, ',');

  v_il: = ' insert into ' |. ' v_tn1 | ' ('| v_cl |') values (';)

  for j in loop c2

  v_vl: = v_vl | Chr (10) | v_id | «, » || v_count | «, » || j.column_name |') ' ;

  v_count: = v_count + 1;

  v_il: = v_il | v_vl;

  end loop;

  dbms_output.put_line (v_il);

  end;

  The problem is with this v_il statement: = v_il | v_vl

  The desired output is to get

  insert into tn1 values (...)

  insert into tn1 values (...)

  .

  .

  But I'm getting

  insert into values tn1 (insert values (...) tn1)

  How to change the code above to get the desired result.

  Also, I'm getting ORA-06502: PL/SQL: digital or value error: character string buffer too small when I run dbms_out.put_line

  Please advice.

  I did a minor change, and it seems to work now.

  What I did:

  Declared all the variable as a CLOB

  And modified

  v_vl: = v_vl | Chr (10) | v_il | v_id | «, » || v_count | «, »...

  v_count: = v_count + 1;

  end loop;

  dbms_output.put_line (v_vl);

  The above change worked. Thank you.

• Dynamic creation of components on the page giving problems

  Hello
  
  We create a number of custom components to interface dynamic user on the page, according to the information, we know that when running (for some reason, we could simply not create them statically and hide and show them dynamically: Please don't suggest that you do this at the moment).
  
  Custom components are derived from elements of the ADF, so, for example:
  

  public class MyRichInputText extends RichInputText implements Serializable {
  }

  They are created dynamically in a bean that is associated with a button and used for the first time. In other words, once wle browse page, for example via tabs, or fragments, still get us an exception "Session timeout". Here is the log of the server:

• dynamic action on the selected value shuttle

  Hello

  Can anyone help me in this.

  I guess a requirement

  There is a shuttle Apex and multiple selection is allowed

  and there are values such as:-others, first, second

  but when we choose other no other value should be able to select

  in what other is selected in the shuttle a textbox is displayed by dynamic action

  can you give me a link for the dynamic creation of checkbox

  FOR EXAMPLE BASED ON CREATED LOV SHARE COMPONENT

  Select the column name as the name of column d, r

  the name of the table

  Boxes are just another way to make a LOV. For a dynamic set of checkboxes, the standard pair of value/label LOV SQL projection is required in the definition:

  select initcap(dname) l, to_char(deptno, 'tm9') v from dept
  order by v asc
  

  If additional values are required, they can be included in the query using unions:

  select initcap(dname) l, to_char(deptno, 'tm9') v from dept
  union all
  select 'Other', 'OTHER' from dual
  order by 2 asc
  

  Checkbox events can be handled by dynamic actions as indicated on page 586 of your test App. Note that I prefer to enable and disable the controls on form rather than hiding and showing them that there is less confusion for the user. It is simple to change the disable/Enable dynamic actions to hide and show if necessary.

• Dynamic link between the first problem and speedgrade CC 2014

  Hello Eveyrne!

  I have trouble to back and forth from first to speedgrade. For example, I can send the images to speedgrade, my image quality and come back to the to first with my settings in place. However, how to get back in the category of speed (of creation) if I need to add a finishing touch? It seems that the only options are just all send in grade speed once again, but there my previous settings in place I start from scratch... I hope I made that clear.

  Thank you

  Moment of clarity: is the link Direct from PrPro/Sg and dynamic links to the PrPro/Ae. They are not even close to the same process of sub hood, and due to the proximity of the nomenclature selected to more trouble they should have created. Adobe LIKES having both be a 'DL'... and 'their' it is very clear. Given that we users like usually jump using long verbiage... including the two acronyms it is STUUPID on someone the part but oh, that's just my personal opinion spouting off here... and Yes, I spoke with members of the staff of Adobe in the conversations of real (like many others) life and 'they' know my thoughts. So I'm not dissing anyone here that I haven't talked... and laughed... on this subject in person.

  Then... you can take your project in Sg, grade it, click on the back of PrPro icon & return to work in PrPro, but when "send you to Sg' to return to the Sg of the prior work does not appear?

  If this is the case, it's weird and NOT expected behavior. I go come & constantly back... sometimes within PrPro, sometimes actually just starting Sg and choose a project of PrPro I know I need to change some more. It is recorded above PrPro, should it show me latest project settings from there.

  To be clear, the process requires that whenever you go forward and backward, to each stage... the project is saved & so updated. If say you let open Sg, even more on a project work on PrPro but does not save, then just raise Sg again... There will be a project file updated yet so that it works on. So... work in PrPro, "send to...". ", the project is saved, & you leave. Work in the Official Journal, either use the 'save' icon or click the 'Return to the PrPro' which requires a backup operation... then PrPro, use it "send to" new requiring a save operation.

• Tables created in a stored procedure cannot be used with dynamic SQL? The impact?

  There is a thread on the forum which explains how to create tables within a stored procedure (How to create a table in a stored procedure , however, it does create a table as such, but not how to use it (insert, select, update, etc.) the table in the stored procedure.) Looking around and in the light of the tests, it seems that you need to use dynamic SQL statements to execute ddl in a stored procedure in Oracle DB. In addition, it also seems that you cannot use dynamic SQL statements for reuse (insert, select, update, etc.) the table that was created in the stored procedure? Is this really the case?
  
  If this is the case, I am afraid that if tables cannot be 'created and used"in a stored procedure using the dynamic SQL, as is the case with most of the servers of DB dynamic SQL is not a part of the implementation plan and, therefore, is quite expensive (slow). This is the case with Oracle, and if yes what is the performance impact? (Apparently, with Informix, yield loss is about 3 - 4 times, MS SQL - 4 - 5 times and so on).
  
  In summary, tables created within a stored procedure cannot be 'used' with dynamic SQL, and if so, what is the impact of performance as such?
  
  Thank you and best regards,
  Amedeo.

  Hi, Frank.

  Thank you for your response. I understand that the dynamic SQL is required in this context.

  Unfortunately, I am yet to discover "that seeks to" using temporary tables inside stored procedures. I'm helping a migration from MySQL to Oracle DB, and this was one of the dilemmas encountered. I'll post what is the attempt, when more.

  In Oracle, we use [global temporary Tables | http://www.psoug.org/reference/OLD/gtt.html?PHPSESSID=67b3adaeaf970906c5e037b23ed380c2] aka TWG these tables need only be created once everything like a normal table, but they act differently when they are used. The data inserted in TWG will be visible at the session that inserted data, allowing you to use the table for their own temporary needs while not collide with them of all sessions. The data of the TWG will be automatically deleted (if not deleted programmatically) when a) a commit is issued or b) the session ends according to the parameter that is used during the creation of the TWG. There is no real need in Oracle to create tables dynamically in code.

  I noticed that many people say that the "Creation of the tables within a stored procedure" is not a good idea, but nobody seems necessarily explain why? Think you could elaborate a little bit? Would be appreciated.

  The main reason is that when you come to compile PL/SQL code on the database, all explicit references to tables in the code must correspond to an existing table, otherwise a djab error will occur. This is necessary so that Oracle can validate the columns that are referenced, the data types of those columns etc.. These compilation controls are an important element to ensure that the compiled code is as error free as possible (there is no accounting for the logic of programmers though ;)).

  If you start to create tables dynamically in your PL/SQL code, so any time you want to reference this table you must ensure that you write your SQL queries dynamically too. Once you start doing this, then Oracle will not be able to validate your SQL syntax, check the types of data or SQL logic. This makes your code more difficult to write and harder to debug, because inevitably it contains errors. It also means that for example if you want to write a simple query to get that one out in a variable value (which would take a single line of SQL with static tables), you end up writing a dynamic slider all for her. Very heavy and very messy. You also get the situation in which, if you create tables dynamically in the code, you are also likely to drop tables dynamically in code. If it is a fixed table name, then in an environment multi-user, you get in a mess well when different user sessions are trying to determine if the table exists already or is the last one to use so they can drop etc. What headache! If you create tables with table names, then variable Dynamics not only make you a lot end up creating (and falling) of objects on the database, which can cause an overload on the update of the data dictionary, but how can ensure you that you clean the tables, if your code has an exception any. Indeed, you'll find yourself with redundant tables lying around on your database, may contain sensitive data that should be removed.

  With the TWG, you have none of these issues.

  Also, what is the impact on the performance of the dynamic SQL statements in Oracle? I read some contrasting opinions, some indicating that it is not a lot of difference between static SQL and SQL dynamic in more recent versions of Oracle DB (Re: why dynamic sql is slower than static sql is this true?)

  When the query runs on the database, there will be no difference in performance because it is just a request for enforcement in the SQL engine. Performance problems may occur if your dynamic query is not binding variable in the query correctly (because this would cause difficult analysis of the query rather than sweet), and also the extra time, to dynamically write the query running.

  Another risk of dynamic query is SQL injection which may result in a security risk on the database.

  Good programming will have little need for the tables of dynamically created dynamically or SQL.

• "the creation of the video preview failed" to DV (firewire) and USB webcam camera

  Device Manager reports the two devices "working properly", but all attempts to use their failure any software I use.  The error varies with the software package.  Trying to get a preview of the video via "My Computer" results in the error "the creation of the video preview failed".

  Devices used for work several months ago but I don't remember exactly when they stopped working.  A Service Pack or some other Windows Update update may have caused the problem (not sure).

  Any help would be greatly appreciated.

  [My system: Windows XP (Media Center Edition), Service Pack 3, Dell Dimension, Intel Core 2, 1 GB of RAM]

  Nevermind, it works now.  For those who have the same problem, here's what I did to remedy.

  1. take DirectShowSpy.dll of Roman Ryltsov http://alax.info/blog/777 and at the command prompt, type "regsvr32 DirectShowSpy.dll" to save it.  (In fact, I used a previous incarnation, also by Roman Ryltsov, called FilterGraphSpy.dll that I had downloaded previously).

  2 - try to use your webcam or your DV camera again.  If it works, you can uninstall DirectShowSpy.dll by typing "regsvr32 /u DirectShowSpy.dll".  My camera and webcam continued to work properly after I uninstalled it FilterGraphSpy.dll.

  That's all.  Although I did some DirectShow programming, I don't know the reasons detailed why this would clearly be this specific problem.  Roman could.  Good luck.

  Some experiments to try.

  (1) create a small project with just a few pictures and see if it will play.

  (2) use .bmp photos to create the project instead of .jpg photos.

  (3) remove all transitions and resave the project as .wmv and see it it helps.

• Reference Dell backup and restore - "an error occurred during the creation of the backup of the system"

  I have a Dell XPS-8700 running Windows 7.  I bought the Dell Backup and Recovery Premium Edition.

  I was able to create a backup bootable (hot spare), and I can create a backup of data on my external hard drive.  However, whenever I try to create a backup on my external hard drive system, after about three seconds in the process, he returned: "an error occurred during the creation of the backup of the system.

  How can I create a backup of the system?  Why I get this error?

  Thanks for all the info. My situation sounds very similar to yours.

  I removed using Add/REMOVE programs in the control panel DBR and he removed cleanly.

  V1.7.1.2 downloaded and executed new facility.

  When I ran, it was my premium license key so he had yet to register and was not removed by uninstall.

  As before, Rescue Disk ran and installed the new partition (DBR_BOOT) on WD Passport.

  However, backup system immediately stopped with disconnected, missing target location or full. Tried several times...

  In any case, sounds like you have solved your problem, so you like OP should this brand this post/thread as answered. I will continue to post on my other thread.

• Independent migration of LWAPP and dynamic interfaces on the controller 4404

  We are currently migrating from a stand-alone environment. Access points currently take wireless clients and put

  their right in separate VLANs that SSID that they associate with. Each SSID is another customer

  So we are essentially acting as a service provider. We try not to get involved with the functions of layer 3.

  Each range of IP of SSID is ordered by a customer or a third party. So far, we didn't specify an address from DHCP server, the client is getting on one VLAN and it is up to the customer to assign their own intellectual property details.

  Now that we're migrating to LWAPP I found the following-

  -J' need to specify an IP address for each dynamic IP address for each WLAN

  -J' need to specify a DHCP server for each dynamic IP address for each WLAN

  Because I have no control of the PPE, I put in the details of false dynamic Interface but the correct address of the DHCP server.

  It seems to work.

  My questions are as follows:-

  1 / is there a way I can simply place clients in a VIRTUAL LAN using LWAPP equipment so we didn't

  get involved with Layer 3 configuration?

  2 / I noticed when I got a DHCP address on a test laptop client, the DHCP server is 1.1.1.1. The only thing in the network that I know is the virtual IP address of the controller that is used for groups of mobility. Is this normal?

  3/on the controller is the query DHCP has passed from the management or the dynamic interface?

  3 / What is the IP address of the dynamic interface actually used for? At the beginning I forge the DHCP server use it as a source, but my setup works with a bogus address.

  Welcome to the world of LWAPP! It's a pretty confusing to get, so I hope I can answer some of your questions.

  Before directly answering your questions, I want to give you a little if a glimpse as to how traffic flows in LWAPP environment. All traffic LWAPP is placed in a tunnel to the controller (this is why LWAPP APs is no longer need to switch trunk links). Traffic is désencapsulé and sent to the appropriate interface switching environment (management or dynamic). The source address for traffic is changed to match the control interface for traffic must return to the controller in order to get the customer. For example, IP addresses are required on the controller.

  1. think of the controller as a layer 3 switch that masks the identity of its customers. By sourcing all traffic from itself, it ensures that all traffic comes back to him, how it forwards traffic to the client via the LWAPP tunnel. False addresses you entered are actually being used on the network, then you will want to register those with the people in charge. If someone uses this address, it will eventually drop your wireless network.

  2. it is normal. The virtual IP address is also used for DHCP service. Because the controller blocks all emissions, it must the DHCP proxy for each client, where the virtual IP address as well as the need to specify the address of the DHCP server.

  3. I don't know what interface it gets passed on. Maybe someone else can answer.

  4. see above for a description of what it is.

  One last thing. What, exactly, are these fake addresses to which you refer? They are real addresses which comes with? They correspond to the VLAN that you places on? You give them suitable default gateways?

  Don't forget that by configuring these, they are real addresses on your network that you should be able to ping. And yet once, if the address is duplicated on the network, it has the potential to get to the bottom of your wireless network.

  Let me know if this can help, and if you have any other questions!
