When to recreate queues and tables of the queue in QA?

When recreate us queues and queue tables when you use Advanced Queuing? Is there an advantage in doing this?

dbms_aqadm.stop_queue)
dbms_aqadm.drop_queue)
dbms_aqadm.drop_queue_table)

dbms_aqadm.create_queue_table)
dbms_aqadm.create_queue)
dbms_aqadm.start_queue)

Also, can you please let me know what is the difference between the queue and queue table? I'm newbie and not able to get help on that. I had a little of that first we can create the queue table and then create the queue. Any help would be appreciated.

Why do you want to "recreate" the queues and queue tables?

Read the documentation of

DBMS_AQADM.ALTER_QUEUE
and
DBMS_AQADM.ALTER_QUEUE_TABLE

and see if you can get out without falling and re - create

In the contrary case; do some reading on how to manage queues, to drop, modification and creation!

http://download.Oracle.com/docs/CD/B19306_01/server.102/b14257/aq_admin.htm#i1005956
and
http://download.Oracle.com/docs/CD/B19306_01/server.102/b14257/aq_admin.htm#i1006297

If you want to change the payload type, you need to remove the queue and re-create it, in which case read on drop, keep in mind the STOP_QUEUE!
http://download.Oracle.com/docs/CD/B19306_01/server.102/b14257/aq_admin.htm#i1006355

Similarly for the DROP table queue!

  • When I click on a table in the left, the tab page replaces the previous

    Hi all

    When I click on a table in the left tree, the tab page replaces the previous, how to disable this feature? These are inconveniences because I view each design of the table of different tab pages.

    anyone here have any suggestions? really appreciate it.

    You have 2 ways to do this:

    (1) when you open a table, click on the pin located in the upper right of the open tab button, it locks this table and a new one will open in a new tab, it works only once, so you can locate only the tables that you really do need to stay open.

    (2) you can set the property ' automatically Viewer gel "(or something like that) in

    Tools-> preferences-> database-> Object Explorer

    This will automatically locate each table you open.

    When exporting my image in LR I select my brand of water in the drop-down list. Then I need to select 'Edit watermark' since the same drop-down menu in order to replace it. When I do that and click 'done' the watermark disappears in the box menu to export. When I click on "Export" the image exports WITHOUT my watermark. Help, please. As I did about everything that has been suggested in this forum and I still have this problem.

    I saw that too. For now, the workaround is that if you select 'Edit watermark,' when you are done editing be sure to reselect the same watermark. If you do not, the watermark menu will be empty.

    It seems to be a known bug that occurs only in the current version. If all goes well, it can be fixed in the next update. There is a page for her on the Photoshop/Lightroom Feedback site. I've added my vote to the page:

    We have identified two questions:

    (1) muse implements a markup bad comment, causing in the edition (IBE) browser to display the page properly. Only, this affects IBE and does not affect the published site. The combination of page that causes the bad markup is still TBD.

    (2) IBE does not account for the bad markup that leads to incorrect DOM, leaving IBE unusable.

    We have a fix for IBE (as BC) who is ready to be tested. We will update this thread when the fix is on.

    Sorry for the inconvenience.

  • Firefox is very slow when you use Facebook, and most of the time it can open positions 2-3 in the 'Newsfeed' instead of much more openness.

    Today when I log in to Facebook through Firefox, it opens only 2 or 3 posts by the news feed (it happens very often, but not always). As I can remember, I've ever known such a problem in the past, with the exception of the rare and occasional accidents which were solved instantly. I am facing this problem for 5-6 months.

    Whenever I face such a problem with Firefox, I log in to Facebook through Google Chrome to check if my internet connection works correctly and have found no such problem with Google Chrome. I also checked to see if this problem is caused by an update hidden applications or anti-virus automatic scan, but found nothing. I also tried "Refresh Firefox - discount to zero and settings modules" and uninstall and reinstall but the problem was not solved. All solutions, please?

    Please make sure that there is not a problem with any acceleration addons or material by trying Safe Mode:

  • MovieClips, buttons and tables - oh the joys

    I have a question also work with arrays, im not much less fpash but decided to try a different approach to writing over and over again the same functions to different buttons.

    The plan is intended to be:

    6 buttons in movieclip on the stage (markers) and 6 boxes of movieclip on the stage (panels). Click on a marker and the fade, it plays in the animation in the control panel.

    access/call the close button.onRelease function; situation within the animation movieclip movieclip original panel (p1.p1_an.close_btn) then call rewindframes(); to falter again the sign in box departure.

    Repeat for all 6 buttons and clips.

  • How to set a menu of VI function to generate a copy of it self when it is move and dropped on the block diagram

    Is any way to put a VI that I placed on a palette in the menu functions to create a copy of it self when I place it on the block diagram?

    My example is as follows. I create a palette for a messaging configuration. The 'send message', 'message' and so forth will work normally with just called when necessary. But 'Create queues messge' must be specific for each instance, because I'm going to create a different number of queues each time I use it. (See system messages in queue OR for the "Continous Measument and Logging" model).

    So every time I drag and drop that VI (Create message Queues) in the palette, I want that it ask me where I want to save the VI.

    Is this possible?
