performance - pl/sql Stored procedure... where does the execution time go? -

-

I'm currently detecting a performance leak in a stored procedure last "end" (I before ) before putting an accurate timestamp after an initial "start" and that process seems abt. 10 seconds to finish, however, I have to wait 2 minutes + to finish it.

Can anyone tell me where the rest of the time goes? I am using Oracle SQL Dev but it does not look useless for the rest of the time, the process is locked on the related table: (

Thank you very much for the educator.

Edit: Thanks again for your input :) Here is the stripped code for the process, depending on the number of items to be processed, in the first part ABT 10 to 40 seconds, the second volume is a few milliseconds, although this process takes 2 to 8 minutes to run. Also, the table that destroys the data is locked for some time, due to which the inserts are postponed. BTW, there is no difference in starting this as a scheduled job. 

  Process to create or change process is MY_PROCEDURE start_procedure number; Start_delete number; End_processor number; Start_procomure: = dbms_utility.get_time; Start - stripped: some selection / update ends here; Committed; Start_delete: = dbms_utility.get_time; Start - Snatched: Clear some other data here; Committed; End_procedure: = dbms_utility.get_time; Dbms_output.put_line ('Process Taken:' to_char ((end_procedure-start_procedure) / 1000)); Dbms_output.put_line ('updated:' to_char ((start_delete-start_procedure) / 1000)); Dbms_output.put_line ('deleted:' || to_char ((end_procedure-start_delete) / 1000)); End;

I think you need to divide by 100, not 1000 (dbms_utility .get_time gives time in Sentixand) It should give you 100 seconds, which is about 2 minutes.

However, if you are interested in finding out where the 2-minute execution time was and the complexity of the process, you either want to do the following:

    < Li> Use a PL / SQL hierarchical profiler () to collect a statistic report report before taking the snapshot before and after the process runs

Profiler can be better if you have too many PL PL / SQL process calls Statspack report may be better if you have mostly SQL statements inside the stored procedure.

Here's what the profiler output looks like:

After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

What is expire header and how to achive them in ASP.NET and PHP? -

I have examined the performance statistics of my website today. I have received a warning (or error may occur) that is given below Add Terminal Headers Here are 15 static components without a 15-futures end date * (no end) Http://www.example.com/video/css/global.css * (no time limit) http://www.example.com/video/js/global.js * (no expiration ) Http: //www.example.com/video/images/main-bg.png what it means and how to achieve it both in PHP and ASP.Net. I am on a shared hosting server, so please tell me some ways to use the code, because I can not make any modifications at the end of the server. If I expire the header, then there is no chance that if I make changes to the CSS, then the user will not be able to remove them immediately because CSS and other files have a fixed time limit (1 month, week ) Are cached for. Is Is there any harm to using PHP? $ time = time () + 3 * 24 * 60 * 60; // 3 day headings ('End:'. GMDAT ('D, D MYH: i: s \ g \ m \ t',

sql server - How can I determine which of my SQL 2005 statistics are unused? -

-
After a few years, one of my biggest databases has deposited 73 figures out of its largest tables. With Indexes, I can run many types of reports and queries, how often / heavily specific indexes are used. What is an equivalent for data? We are running SQL 2005. To make statistics automatically managed and honest, I would like to "update statistics", "create statistics" and There is no information about any management except "drop statistics" orders. In theory, UPDATE should handle the addition and removal of statistical data. In addition, I've never heard about the amount of storage or storage taking in large amounts, so I'm not sure whether there is any reason for the alarm or not. If you are seeing a potential problem, then I would suggest running an update before, if it does not clean it, it is leaving and then it appears to be safe operation (because it is the only query optimizer Is for). I will not leave "left" in the
