    <p>I think you need to be dividing by 100, not 1000(dbms_utility.get_time gives time in centiseconds). That should give you 100 seconds, which is about 2 minutes.</p> <p>However, if you're interested in finding out where the 2 minutes of execution time went, and depending on the complexity of the procedure, you may want to either:</p> <ul> <li>collect a statspack report by taking snapshots before and after the procedure runs </li> <li>use the PL/SQL Hierarchical Profiler(<a href="http://download.oracle.com/docs/cd/B28359_01/appdev.111/b28424/adfns_profiler.htm#CHDCIGIB" rel="nofollow noreferrer">http://download.oracle.com/docs/cd/B28359_01/appdev.111/b28424/adfns_profiler.htm#CHDCIGIB</a>). </li> </ul> <p>The profiler may be better if you have a lot of chained PL/SQL procedure calls. The statspack report will be better if you have mostly sql statements inside the stored procedure.</p> <p>Here's what the Profiler output looks like:</p> <pre><code>Sample Report Function Elapsed Time (microsecs) Data sorted by Total Subtree Elapsed Time (microsecs) 2831 microsecs (elapsed time) &amp; 12 function calls Subtree Ind% Function Descendant Ind% Calls Ind% Function Name 2831 100% 93 2738 96.7% 2 16.7% __plsq_vm 2738 96.7% 310 2428 85.8% 2 16.7% __anonymous_block 2428 85.8% 15 2413 85.2% 1 8.3% HR.TEST.TEST (Line 1) 2413 85.2% 435 1978 69.9% 3 25.0% HR.TEST.TEST.FOO (Line 3) 1978 69.9% 1978 0 0.0% 3 25.0% HR.TEST.__static_sql_exec_line5 (Line 5) 0 0.0% 0 0 0.0% 1 8.3% SYS.DBMS_HPROF.STOP_PROFILING (Line 53) </code></pre>

    1. COphew, looks complicated (i am a pl/sql/oracle newbie), but I'll have a look at it... thank you but I am still wondering whether dbms_utility.get_time is completely useless, then... well not completely maybe, but at least very much :-?

    2. COAre you familiar with how to collect a statspack report? That is probably the easiest way to get started as a new user. It will tell you which statements are responsible for the most time and what is making them slow.

    3. COBasically, I am very new to all of this - that's why I thought outputting timestamps would be the easiest way to find the problem... I'll have a look at that statspack thing... thank you very much

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
