Execution Time Format

I want to get rid of the decimal portion of the Execution Time that prints on my test report. At a minimum, I want it to display only one significant digit. Below is the expression that is found in the reportgen_txt.seq for the
f(x)Add Execution Time. What I'm wondering is, 1) how do I modify the format, 2)In general, how do I find out what is allowable in this expression.
Locals.Header += Str(ResStr("MODEL", "RPT_HEADER_EXEC_TIME"), "%-30s") + (PropertyExists("Parameters.MainSequenceResults.TS.TotalTime") ? Str(Parameters.MainSequenceResults.TS.TotalTime, Parameters.ReportOptions.NumericFormat , 1, True) + ResStr("MODEL", "RPT_HEADER_SECONDS") : ResStr("MODEL", "RPT_NOT_APPLICABLE")) + "\n"

Hi,
The format for the Str() is Str(value, , , , )
as you can see the format string is the second parameter. This is normally Parameters.ReportOptions.NumericFormat which is set as default in the Configuration Report Options as %$.13f, this is a C (printf) style format string. Which is a float with 13 places of precision.
Therefore you can changes this to say %$.1f which would be 1 place of precision.
Dont change it in the Configuration Report Options because this will affect everything, such the results, limits and so.

Can the format of a SQL Statement modify the execution time of an SQL ....

Can the format of a SQL Statement modify the execution time of an SQL statement?
Thanks in advance

It depends on:
1) What oracle version are you using
2) What do you mean for "format"
For example: if you're on Oracle9i and changing format means changing the order of the tables in the FROM clause and you're using Rule Based Optimizer then the execution plan and the execution time can be very different...

Hello All,
I'm making a Java SQL Client. I have practicaly all basic work done, now I'm trying to improve it.
One thing I want it to do is to allow the user to specify new drivers and to use them to make new connections. To do this I have this class:
public class DriverFinder extends URLClassLoader{
private JarFile jarFile = null;
private Vector drivers = new Vector();
public DriverFinder(String jarName) throws Exception{
super(new URL[]{ new URL("jar", "", "file:" + new File(jarName).getAbsolutePath() +"!/") }, ClassLoader.getSystemClassLoader());
jarFile = new JarFile(new File(jarName));
System.out.println("-->" + System.getProperty("java.class.path"));
System.setProperty("java.class.path", System.getProperty("java.class.path")+File.pathSeparator+jarName);
System.out.println("-->" + System.getProperty("java.class.path"));
Enumeration enumeration = jarFile.entries();
while(enumeration.hasMoreElements()){
String className = ((ZipEntry)enumeration.nextElement()).getName();
if(className.endsWith(".class")){
className = className.substring(0, className.length()-6);
if(className.indexOf("Driver")!=-1)System.out.println(className);
try{
Class classe = loadClass(className, true);
Class[] interfaces = classe.getInterfaces();
for(int i=0; i<interfaces.length; i++){
if(interfaces.getName().equals("java.sql.Driver")){
drivers.add(classe);
Class superclasse = classe.getSuperclass();
interfaces = superclasse.getInterfaces();
for(int i=0; i<interfaces.length; i++){
if(interfaces[i].getName().equals("java.sql.Driver")){
drivers.add(classe);
}catch(NoClassDefFoundError e){
}catch(Exception e){}
public Enumeration getDrivers(){
return drivers.elements();
public String getJarFileName(){
return jarFile.getName();
public static void main(String[] args) throws Exception{
DriverFinder df = new DriverFinder("D:/Classes/db2java.zip");
System.out.println("jar: " + df.getJarFileName());
Enumeration enumeration = df.getDrivers();
while(enumeration.hasMoreElements()){
Class classe = (Class)enumeration.nextElement();
System.out.println(classe.getName());
It loads a jar and searches it looking for drivers (classes implementing directly or indirectly interface java.sql.Driver) At the end of the execution I have found all drivers in the jar file.
The main application loads jar files from an XML file and instantiates one DriverFinder for each jar file. The problem is at execution time, it finds the drivers and i think loads it by issuing this statement (Class classe = loadClass(className, true);), but what i think is not what is happening... the execution of my code throws this exception

How to improve the execution time of my VI?

My vi does data processing for hundreds of files and takes more than 20 minutes to commplete. The setup is firstly i use the directory LIST function to list all the files in a dir. to a string array. Then I index this string array into a for loop, in which each file is opened one at a time inside the loop, and some other sub VIs are called to do data analysis. Is there a way to improve my execution time? Maybe loading all files into memory at once? It will be nice to be able to know which section of my vi takes the longest time too. Thanks for any help.

Bryan,
If "read from spreadsheet file" is the main time hog, consider dropping it! It is a high-level, very multipurpose VI and thus carries a lot of baggage around with it. (you can double-click it and look at the "guts" )
If the files come from a just executed "list files", you can assume the files all exist and you want to read them in one single swoop. All that extra detailed error checking for valid filenames is not needed and you never e.g. want it to popup a file dialog if a file goes missing, but simply skip it silently. If open generates an error, just skip to the next in line. Case closed.
I would do a streamlined low level "open->read->close" for each and do the "spreadsheet string to array" in your own code, optimized to the exact format of your files. For example, notice that "read from spreadheet file" converts everything to SGL, a waste of CPU if you later need to convert it to DBL for some signal processing anyway.
Anything involving formatted text is not very efficient. Consider a direct binary file format for your data files, it will read MUCH faster and take up less disk space.

Execution time difference between Statspack and DBM_Monitor trace

Hi Everyone,
We noticed that output of query execution time is quite differ between statspack and session tracing (DBMS_MONITOR) report. The query execution time in Statspack was 1402 sec and in session trace file was 312.25 Sec. FYI database version is 11.2.0.3 which is installed on platform OL 5.8
Both of the following reports (Staspack/tracing) was executed on same system and at the same time. Could you suggest why execution time is differ in staspack and session tracing?
Staspack execution time :-

Hi,
First of all, please read the [url https://wikis.oracle.com/display/Forums/Forums+FAQ]FAQ page and find out how to use the code tags to format your output properly so that it's readable.
I don't want to work out the stats formatting but I'd guess that if you ran the query first time and the data was not cached, it would be slower than the 2nd query when it was cached. The stats should confirm this so please format them so we can see it properly.

Workbook Execution time...

Hi friends
i have one report which takes more than 20 mins. query can give o/p of 50000 rows. now tell how i can reduce the execution time. my query is well tuned. and giving minimum cost. but still in discoverer it takes 20 min. can u tell me how i can reduce the execution time(it should be executed 2-3 mins . should i go for high configuration PC?
thanx.....

Hi,
You need to establish where the report is waiting to complete. If the report is waiting for the database query to finish then tuning the database query will improve performance. If the you are using Discoverer Desktop or Plus then you may be waiting for the PC to sort and format the results and so upgrading the PC will help, or if you are using Discovere Plus or Viewer you may be waiting for the Application Server to process the report so tuning the Application server may improve the timings.
You say "my query is well tuned. and giving minimum cost". The cost of the query tells you nothing. You need to examine the query execution plan and benchmark the query before to determine the optimum query plan.

Execution times and other issues in changing TextEdit documents

(HNY -- back to terrorize everyone with off-the-wall questions)
--This relates to other questions I've asked recently, but that may be neither here nor there.
--Basically, I want to change a specific character in an open TextEdit document, in text that can be pretty lengthy. But I don't want pre-existing formatting of the text to change.
--For test purposes the front TextEdit document is simply an unbroken string of letters (say, all "q's") ranging in number from 5 and upwards. Following are some of the results I've gotten:
--1) Using a do shell script routine (below), the execution is very fast, well under 0.1 second for changing 250 q's to e's and changing the front document. The problem is that the formatting of the first character becomes the formatting for the entire string (in fact, for the entire document if there is subsequent text). So that doesn't meet my needs, although I certainly like the speed.
--SCRIPT 1
tell application "TextEdit"
set T to text of front document
set Tnew to do shell script "echo " & quoted form of T & " | sed 's/q/e/g'"
set text of front document to Tnew
end tell
--END SCRIPT 1
--The only practical way I've found to change a character AND maintain formatting is the "set every character where it is "q" to "e"" routine (below). But, for long text, I've run into a serious execution speed problem. For example, if the string consists of 10 q's, the script executes in about 0.03 second. If the string is 40 characters, the execution is 0.14 second, a roughly linear increase. If the string is 100 characters, the execution is 2.00 seconds, which doesn't correlate to a linear increase at all. And if the string is 250 characters, I'm looking at 70 seconds. At some point, increasing the number of string characters leads to a timeout or stall. One interesting aspect of this is that, if only the last 4 characters (example) of the 250-character string are "q", then the execution time is again very quick.
--SCRIPT 2
tell application "TextEdit"
set T to text of front document
tell text of front document
set every character where it is "q" to "e"
end tell
end tell
--END SCRIPT 2
--Any insight into this issue (or workaround) will be appreciated.
--In the real world, I most often encounter the issue when trying to deal with spaces in long text, which can be numerous.

OK, Camelot, helpful but maddening. Based on your response. I elected to look at this some more, even though I'm stuck with TextEdit on this project. Here's what I found, not necessarily in the order I did things:
1) I ran your "repeat" script on my usual machine (2.7 PPC with 10.4.6)) and was surprised to consisently get about 4.25 seconds -- I didn't think it should matter, but I happened to run it with Script Debugger.
2) Then, curious as to what a slower processor speed would do, I ran it at ancient history speed -- a 7500 souped up to 700 MHz. On a 10.4.6 partition, the execution time was about 17 seconds, but on a 10.3.6 partition it was only about 9.5 seconds. (The other complication with this older machine is that it uses XPostFacto to accommodate OS X.) And I don't have Script Debugger for 10.3.x, so I ran the script in Script Editor on that partition.
3) That got me wondering about Script Editor vs. Script Debugger, so (using 10.4.6) I ran the script on both the old machine and my (fast) usual machine using Script Editor. On the old machine, it was somewhat faster at about 14 seconds. But, surprise!, on the current machine it took twice as long at 8.6 seconds. The story doesn't end here.
(BTW, I added a "ticks" routine to the script, so the method of measuring time should be consistent. And I've been copying and pasting the script to the various editors, so there shouldn't be any inconsistencies with it. I've consistently used a 250-character unbroken string of the target in a TextEdit document.)
4) Mixed in with all these trials, I wrote a script to get a list of offsets of all the target characters; it can be configured to change the characters or not. But I found some intriguing SE vs. SD differences there also. In tests on the fast machine, running the script simply to get the offset list (without making any changes), the list is generated in under a second -- but sometimes barely so. The surprise was that SE ran it in about half the time as SD. although SD was about twice as fast with a script that called for changes. Go figure.
5) Since getting the offset list is pretty fast in either case, I was hoping to think up some innovative way of using the offset list to make changes in the document more quickly. But running a repeat routine with the list simply isn't innovative, and the result is roughly what I get with your repeat script coupled with an added fraction of a second for generating the list. Changing each character as each offset is generated also yields about the same result.
My conclusion from all this is that the very fast approaches (which lose formatting) are changing the characters globally, not one at a time as occurs visibly with techniques where the formatting isn't lost. I don't know what to make of SE vs. SD, but I repeated the runs several times in each editor, with consistent results.
Finally, while writing the offset list script, I encountered a couple AS issues that I've seen several times in the past (having nothing specifically to do with this topic), but I'll present that as a new post.
Thanks for your comments and any others will be welcome.

Queries taking high execution time for zero count

Hi,
i have procedures executing as jobs.
the procedures take a lot of time to execute when the cursor count is zero.
what might be the reason for this?

cursor 1 - select a.col1, b.col1,decode(c.col1,1,c.col1,2,c.col2,null) col3 from a,b,c
where joing conditions
and nvl(c.col3,c.col4) = b.col3
and c.col5 is null
cursor 2 - cursor 1 - select a.col1, b.col1,decode(c.col1,1,c.col1,2,c.col2,null) col3 from a,b,c
where joing conditions
and a.timestamp > sysdate-1
and nvl(c.col3,c.col4) = b.col3
and c.col5 is not nulll
cursor 2 first updates the values of col5 to null
cursor 1 recalculates the value of col5 and updates it.
c is a partitioned table and partition code is also present in the where condition.One question: Since you say that the cursor is "updating", but the cursor is a query, does this mean that you're performing row-by-row processing in a loop?
If yes, you might be better off with doing this in one or two plain SQL statements, which is probably much faster.
Another question: You say that after taking the described measures the performance was significantly better but became again worse after a couple of days again, is this right?
Can you provide more details, what "good" and "bad" performance means, e.g. in terms of execution time?
You might want to check if the execution plans change between the "good" performance and the "bad" performance.
If your table continuously gets data deleted and for some reason the deleted rows are not re-used, e.g. by using direct-path inserts to add new data, then your segment might become larger and larger and you would need to re-organize the table if you use regularly full table scans against it.
The execution plan posted is not really helpful. Try to use DBMS_XPLAN.DISPLAY to get a proper output including the "Predicate Information" section below the plan and specify to which of the two statements the plan corresponds.
Use the {noformat}{noformat} tags to format the plan output properly here in mono-space fonts.

Calculate execution time of procedure

hiii
I create procedure that insert data in multiple tables i want to calculate execution time of procedure the start time
and the end time to insert them in a table .
and i want to calculate the start&end time that the procedure take to insert in each table
i use DBMS_UTILITY.GET_TIME but it gives me in millisecond i want the format DD/MM/YYYY HH:MI:SS
i also use sysdate but it gives un un reasonable time
like the start time more than the end time
how to calculate execution time of procedure???????
thanks

Look at the docs for DBMS_PROFILER.

Process chain total execution time

Hi Experts,
Can you tell me how we can the total execution time taken by the process chain.
Thanks
Suneel

Hi Suneel,
I have understood your requirement : You need start and end timings for each and every run of the chain.
Goto the 1st process type in your process chain - >Right click and click on Display messages - > Go to the chain and copy the variant name from there.(repeat the same for last p.type for end timings of chain)
Now Go to table RSPCPROCESSLOG and insert the Variant name and the date of the chain run.
You will get details of all the runs of that particular chain.
Timings are there in the STARTTIMESTAMP and ENDTIMESTAMP fields.
Timings will not be in the requires format.
It will be like YYYYMMDDTIME.OTHERS
You will have to download it to excel and do some manipulations to take out the digit from 9-14 places.
But I think it will be better b'coz you will have to do that only once.
I have done the same thing in my project as well.
Revert back if you have any problems.

Cut down execution time

So I need to take the execution time of the attached VI down Greatly. it sits at about 10-15 seconds and i need it to be more like 500ms. the issue seems to be with extracting the registers from the modbus return and then formatting them to look correct on the VI. I Have some ideas on cutting this down but they have proved nominal at best. I could really use some suggestions on this. it me last major piece on this project.
thanks,
Mark R.

You haven't supplied all the SubVIs... But I have some suggestions:
I notice that the "MB Ethernet Master Query.vi" SubVI is re-used several times for each of your Drives. If the VI isn't re-entrant then each call will block between drives.
It can take time to open a connection. It looks like this VI is part of a larger application - you are better off keeping the connection open up-front and only performing the reads when needed.
The register conversion logic won't be slowing you down; this will execute very quickly. It is more lilkely that the modbus reads are where time is being spent. But again, without the rest of the SubVIs it is hard to give any further guidance.
It is hard to tell without the SubVI but it looks like you are using a time-out of 10000 seconds for each modbus read. Are you sure one of your requests isn't timing out and adding 10s to your execution time?

Day timer format calendar

Does anyone know of software that can create what you can do with Calendar but in a week at a glance day timer format? IE - a 5 x 7 size with photos on the left and a week calendar on the right?
Thanks!

No I do not - but it sounds like a good suggestion for Apple - iPhoto menu ==> provide iPhoto feedback

During export from Discover to Excel, Time Format changes to Number Format

Hi
I have a seconds column which is of number datatype. But in my report, I am converting the number in *0HH:MI:SS* format. For example, I have *4952534 seconds*. So my report is showing *1375:42:14* which is a Time Format. It looks good when I view the data in Discoverer Viewer or Plus. But when I try to export the data to Excel, the time format gets converted to *4952534 seconds*, which is creating problems. So can you suggest on how can I preserve the formatting during export to excel from discoverer.
Thanks
Sachin

Hi,
Excel will not implement the 0HH:MI:SS data format, it just gets the field as a number. You will have to format the field into text using the calculation from my previous post.
