I left items downloads in the trash, and when I tried to empty the trash I got a notice that it was unable to empty because of some elements. Now, I can not find that notice and I can not open Trash because I get a notice that it's been emptied.
Hi all. I am new to Oracle and I need to also write new data table in a logfile on Linux in order to live in the display screen. My first thought was to write a trigger, and after some research on googled around, I finally came to this:
create or replace trigger foo_insert After Insert on foo for each line declare f utl_file.file_type; s VARCHAR2 (255); Start s: =: new.udate | '-' || : new.time | ' ' || : new.foo | ' ' || : new.bar | ' ' || : new.xyzzy | ' ' || : new.frobozz | ' ' || : new.quux | ' ' || : new.wombat; f: = utl_file.fopen ('BLAH_BLAH', 'current.log', ' a'); UTL_FILE.put_line (f, s); UTL_FILE.fclose (f); end foo_insert;
It seems properly to add new data in the log file as new inserts occur, but open and close the file each time are of course not optimal. In the app real new lines could have inserted every second or two. How can I optimize it? In addition, the log file will be archived and turned every day, so there must be a way to effectively report the relaxation of the oracle to reopen the case.
Thank you!
> I would like to pursue the optimization of the trigger > As Ed suggested you need to think this through a few others and refine the requirements.
You said "I am new to Oracle. So you may not realize that anything a trigger didn't REALLY EVEN HAPPEN! The transaction can still be restored by Oracle or by the appellant. Want that all the 'hiccups' look too? If this isn't the case, then you can not use a trigger to do this. You need the process that translates the trigger being called to do logging after the data is stored.
It should be noted that this requirement is before we can offer solutions to a problem.
Assuming you want the trigger record all attempts change the data, then the best way I know to do that is to minimize the work does the trigger. Another fundamental principle is to follow the advice of the Ed and have a clear separation and distinction between "what" should be done and 'how' to do it.
To minimize the trigger work change proposed Nicosa approach. Create an AUTONOMOUS_TRANSACTION stored procedure that handles the 'how' and just have the trigger to transfer data to the stored procedure values. The trigger provides data; He doesn't know, or care, what is done with the data.
The stored procedure is then free to use the files, a table, write to a file or any other method is proving to be the best. You can change the methods without affecting the trigger.
A queue or table may contain data, but again once you need to think about the obligation. Do you need fair access to data only once? Now, you want a "tail". But what happens if this requirement change tomorrow? You won't have to redesign the architecture.
With a queue once you delete the queue data it won't here later if you want to get it again. With a table you can take as long as you want.
I would like to start by using a table to store the data. If you use a sequence number or "insert_date" value, you can always query the data of interest. The table just collects data. He does not care how to use data.
So, by using proven design principles and knowing that the requirements are for the most part unknown and may change unexpectedly, I would be:
1. create an AUTONOMOUS_TRANSACTION stored procedure that accepts the parameter data and the thicket in a simple logging table. 2. change your trigger to call the procedure to step #1 3. create another procedure that performs a query of 'tail' for you will depend on 'insert_date' number or sequence. This query can write data to a file or return a cursor ref that your script can use to provide data for display.
The approach described above takes each step in the process relatively independent of the other stages.
Until put you the finishing touches to the requirements that you do not want to lock up your initial design.

How to recover my product key of windows 8, I installed the windows 10 techniques view without taking backup I need to go back to my windows 8 pls someone help
Hi Carmen,.
Thanks for posting your query in Microsoft Community Forum.
I understand that you had not taken any prior backup upgrade to Windows 10 Technical Preview and need product key to retrieve Windows 8.
So, first of all, I suggest you to check the product key in email messages when you purchased the license to the product for Windows 8. Once you get the product key, you can create a Windows 8 ISO and reinstall using this product key. See the following article:
However, if you had bought the system pre-installed with Windows 8. Then, you may need to contact the Original Equipment Manufacturer (OEM) system for Windows 8 discs to restore the older operating system.
Hope this information is useful. Let us know the results for further assistance, we will be happy to help you.
I create a Web application for the user to record certain information with multiple images. I only see a single uploader.
How can I add multiple image uploader and how do I create an upload field instead of a custom file upload image?
Hello
There is no other type of upload for web applications field. You will need to use the 'image file type"to apply to multiple file upload fields in the form of web application in this case.
