Changing execution times from recompile in 8.20

Well, we are starting to have some serious problems with LV8.20 and its now compile times. I have read there is compression now in saving VIs which reduced the size of saved files on disk. The problem is that LV8.20 takes MUCH LONGER to recompile a VI after any change than it ever did. We have some seriously large applications and VIs in the neighborhood of 5MB code size that always worked find pre-LabVIEW 8. You could never notice the compile time in LV7.1. Now, you move a wire or add a primitive and the compile time on a 3GHz machine takes 2-3 seconds. It is improssible to code with this delay, any way to turn that "feature" off.
What's worse, is that the execution times of VIs now changes after a recompile. We are seeing this in many of our applications when performance testing and targetting more deterministic code in RT. You recompile the VI and a component that you DID NOT EVEN CHANGE has a very drastic change in performance. I suspect its due to the VI compression/decompression, but that is a guess since it is new and this is the first time we have seen this happening to this extent in LV. Most of our developers have noticed this since switching to LV8.20 and causing us a lot of headaches.
Any workarounds or suggestions?

Hi Mike,
It looks like you are working on this issue with Avinash via phone/email, but for others who may be interested, there are two bugs filed that are somewhat related, one is regarding different execution times depending on the order of unbundling, the other is in regards to slowdowns in the development environment with large projects, where a project with a huge number of VIs takes longer to do things like open the VI Hierarchy, but it does not specifically mention things like moving wires taking a significantly longer period of time. It may be helpful to send a project that can reproduce this also, which you may want to do via email/ftp site.

Execution time from explain plan

Hi
How can i get the execution time of a query from explain plan (not tkprof). I don't see the execution time in the plan table output.
Thanks

Explain plan won't give execution time of a query because:
- it does not execute the query
- it only evaluates the execution plan and gives estimated costs
I dont't know if it is possible to deduce execution time from estimated cost.

How to get the total execution time from a tkprof file

How to change system time from Java

Could someone tell me if there is possibility to change the system time, from within a Java program. And how to do it.

In general, no.
You could do it using JNI if you're running your JVM
with sufficient system privileges.
It seems a highly questionable thing to want to do.
Why do you have a requirement for this?

select * from dev1_soainfra.cube_instance where
(select sum((extract(hour from MODIFY_DATE)-extract(hour from current_timestamp))*3600
+ (extract(minute from MODIFY_DATE)-extract(minute from current_timestamp))*60
+ extract(second from MODIFY_DATE)-extract(second from current_timestamp))*1000 from dev1_soainfra.cube_instance where
COMPONENTTYPE='bpel' and COMPOSITE_NAME='COMPOSITE_NAME' ) > 1000000
and COMPONENTTYPE='bpel' and COMPOSITE_NAME='COMPOSITE_NAME' ;
Replace COMPOSITE_NAME with your actual name of the composite.
Let me know if it works.

Cannot change the time from am to pm in Calendar T...

No matter how I try, the time the reminder/alarm just doesn't change from am to pm. Is there some special trick to that?

Once you've entered the time are you pressing the '7' key (with a 'p' on it) to state that the time is pm?
Alternatively, have you tried entering the time in 24-hour format?

Process Chain changing start time?

hi guysm i have 76 process chains that run every day in BWD system, so i removed all the timings from the start variant and in the infopackages, but it seems some process chains are still running, i did do the following steps on chnaging the time from a particular time to immediate, Save, Check and activate, i didnt schedule it as i dont want it to load right away .
do i have to hit check , save , schedule once i change the time from a particular time to immediate load or activate will work as well.?
what else could be the cause of process chains still loading even there are no events, or time given to any process chains at all.
i went to sm 37 and i can see the bi process are all running at the time they were orignially set up on.
so any suggestions would help,
is there any way from sm 37 i can tell which process chain is triggered off?
thanks
Dante(devils never cry)

Dante, the start conditions on the infopackages do not affect when they run in process chains. The process chains have their own start job. If you want to change the start time of a process chain, then you need to go to maintain the process chain, right-click on the Start process and select Displaying Scheduled Job(s)... . Here you will see a job called BI_PROCESS_TRIGGER. Change the start conditions of this job.
The start job for all process chains is BI_PROCESS_TRIGGER, so using SM37 may be difficult to identify which BI_PROCESS_TRIGGER job is associated to a particular chain.
Also, to let you know, each process in a process chain has an associated job. All jobs called BI_PROCESS_xxxxx are jobs associated with a process chain.
Eg.
BI_PROCESS_LOADING is an infopackage.
BI_PROCESS_TRIGGER is the start job
Does this help?

Query Execution times

Hi All,
I am trying to know the most used queries in our BI system by trying to find out how many times the query has been executed.
we recently upgraded our BI system and I could find the number of times query has been executed by opening this report SAP_BW_QUERY - No.of Executions per BI Application Object.
The problem is that it is showing me the most used reports after upgrade and I would like to know from the last 6 months or 1 year.
I have checked from the old BW statistics multiprovider and they are couple of reports there but none of the reports shows Execution times of queries.
I checked from ST03N and it I got information for only Query runtime.
could someone let me know which report is related to number or execution times from old BW statistics.
thanks

Hi,
Once see no.of Navigations, it is nothing but no of times executed. once check in that queries which allready developed.

Pcrao.

Capturing cfml execution time

Hi, good day to all! Is there any way on how to capture an
execution time of a cfm instruction? I have two situations, but I
think they're similar as shown below:
1st situation:

<cfquery name = "q1" datasource="#db#">
SQL statement
</cfquery>
<cfquery name = "q2" datasource="#db#">
SQL statement
</cfquery>
<cfquery name = "q3" datasource="#db#">
SQL statement
</cfquery>
<cfquery name = "q4" datasource="#db#">
SQL statement
</cfquery>

For the 1st situation above, I want to capture the total
execution time from q1 to q3 only. Also, I want to get the time
each query is executed. Is there any way how?
2nd situation (could be any cfml instructions):

instruction 1............................
instruction 2............................
instruction 3............................
instruction 4............................

In the 2nd situation, I want to get the total execution time
from instruction 1 to instruction 3 only.
Any help is really appreciated. Thanks.
Update ----------------------------------------
By the way, I am using cf 6.1. It seems the gettickcount
technique isn't returning the exact execution time. actually, i
have a code in cf that contains a vbscript. that writes to an excel
file. This is what i did:
start:
..... cf tags here ...
<cfset startTimer = GetTickCount()>
<script language="vbscript">
--- some vbscript and cf statements .........
<cfoutput query = "some_query">
objXL.ActiveSheet.Cells(X_Pos,1).Value = "#some_cf_value#"
objXL.ActiveSheet.Cells(X_Pos,1).Font.size = "#FSize#"
--- some vbscript and cf statements .........
</cfoutput>
--- some vbscript and cf statements .........
</script>
<cfset endTimer = GetTickCount()>
<cfset totalTime_ms = endTimer - startTimer >
end:
totalTime_ms doesn't seem to return the exact length of time
of the process. I mean, From one test, I tried to use a stopwatch
and found out it took about 30 seconds to complete filling the
excel file. But totalTime_ms returns only about 1500 ms, which is
only about 1.5 seconds. The result is far from reality. Why? Is
there any other way? Thanks.

if you wanna know the execution time of the whole page, here
is coding..
put this
<cfset tickBegin = GetTickCount()> on the top row of ur
page.
put this
<cfset tickEnd = GetTickCount()>
<cfset loopTime = tickEnd - tickBegin>
<cfset loopTime = loopTime / 1000>
<cfoutput>Messages Results #count_first# - #count_end#
of about #ListLen(session.topic_replies_list)# for seconds
milliseconds. (#loopTime# seconds)</cfoutput>
at the bottom row of ur page.

AJAX, how to check execution time of queries?

CF8, using CFDIV to bind to a CFC. The CFC has several SQL
queries, including select, insert, update, delete. I need to check
the execution time of these queries. I have the CF Ajax logger
turned on (cfdebug), but it doesn't seem to list query execution
times. I see the query execution times from normal form pages in
the log info on that page, at the bottom as normal, but not the
queries in Ajax binded CFC's.
Am I missing a server setting? I have everything checked in
the Ajax logger. Global, LogReader, http, bind, debug, info,error,
window.
Thanks in advance for any help!
Mike

I use Ajax (in CF7) a lot to access a SQL Server database. To
determine execution times for Ajax queries, I run the application
in Firefox with the "Firebug" add-on. Firebug reports the execution
of each (and every) Ajax transaction in milliseconds.

OSB: reporting via service callout & reporting execution times

Assume I made a common local service for a general report action and it's called from all inbound proxy services. At the moment all I see is in the report database is: inbound service uri: LocalProxy and inbound service name: <my local report service name>. How can I log the original service instead which was called?
An other question: is it possible to report the execution time of the service call into the database as well? I'd prefer having two measures: service execution time from the inbound proxy service until it leaves the ESB with the response; and the called business service execution time.

One space changes query execution time significantly. Why?

Hello,
my application works on Oracle DB 10.2. Today it started "hanging" on one a select query, which earlier took 1-2 seconds to execute (I waited for several minutes and then stopped it). The query is executed, using the following code:
PreparedStatement pst = conn.prepareStatement("select ... ? ... ? ... ? ");
pst.setInt(1, ...);
pst.setString(2, ...);
pst.setInt(3, ...);
ResustSet rs = pst.executeQuery();
So, it started hanging on the executeQuery() method call.
I started experimenting and discovered, that any minimal change to the query (for example, adding 1 adjacent space to the space that is already present) has the result, that query executes in 1-2 seconds again! But if I remove this additional unnecessary space - the query hangs again. This was reproduced with both web application and console application. Computing statistics didn't help.
Several hours later without any interference everything became OK - execution time of that query became 1-2 seconds. But for some time the system was, in fact, unavailable. Why could it happen, how 1 space could make such a great difference and how to prevent this situation in the future?

As others already mentioned you might have a problem where for some unknown reason the execution plan changes from fast to bad.
A completely different idea would be to rewrite the statement, maybe it is possible to find a way where you allways get good plans.
For example I'm not sure if the subquery is needed. If it is then better use alias names inside the subquery too.
Suggestion
select distinct vv.vv_id, vv.value, vv.vocabs_voc_id, vv.com, vv.status, vv.code,
            vv.main_vv_id, vt.vocabs_tree_node_id as node_id
            from vocs_values vv left join vt_vv vt
            on vv.vv_id = vt.vocs_values_vv_id
            connect by prior vv.main_vv_id = vv.vv_id
            start with (vv.vocabs_voc_id = ?
                            and upper(vv.value) like ?
                            and vv.status = ? ); When looking in more detail I see that you alread used an alias from the outer query inside the subquery. Is this correct?
I added some other aliases in blue for the subquery to show you the difference.
Problem?
select distinct vv.vv_id, vv.value, vv.vocabs_voc_id, vv.com, vv.status, vv.code,
            vv.main_vv_id, vt.vocabs_tree_node_id as node_id

            on vv.vv_id = vt.vocs_values_vv_id
            connect by prior vv.main_vv_id = vv.vv_id
            start with vv.vv_id in (select {color:blue}vv2.{color}vv_id

                               and {color:blue}vv2.{color}status = ? );Shouldn't you replace {color:red}vv.{color} with {color:blue}vv2.{color}?

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.

Schedule lines should not change 3 weeks time from MRP date

Hi
Is there any specific customisation required to get following results in case of schedule lines.
1) MRP should not change/adjust the already send delivery schedule lines which are lying within 3 weeks time from MRP date
2) System should not allow to book the GRN unless the messages / print out has been generated from the system in case of scheduling agreement.
Thanking you
Shantakumar
09944009752

Hi,
There are 2 possibilities:
1. use MRP fixing using planning time fences, this is done by putting the relevant settings in the MRP1 view of the material master
2. use the firming options of the scheduling agreement, these are set per material number that is entered in the scheduling agreement.
The GR can only be posted for schedule lines that have been processed aka output generated.
Regards,

How can I prevent the settings on iMessage from changing each time I sync the devices with iTunes on our iMac?

Each time I sync an apple device (iPad, iPad mini, iPhone) with iTunes on our iMac the settings on iMessage and phone settings change. We use the same Apple ID and have different e-mail addresses and phone numbers; however, each time a device is sync'd on iTunes on our iMac, the iMessage settings and phone settings are changed so that we all each get each other's text messages and phone calls. After the device is sync'd/charged, I have to go into each device (all of them somehow update when only one is sync'ing) and re-set the settings to what we want. How can I prevent settings from being changed each time?

Okay I've tried safe mode. Let it run down to 98%, plugged it in, locked the screen, and waited. A few minutes later, the screen came on showing the 100% icon at the top right, full battery icon just to the left of the time, 100% text to the left of that.
I'm not going to do a hard reset until I have confirmation that this is not normal behavior for the phone because that's going to take hours of my time and gigabytes of data transfer to get all of my media and apps back on the phone and configured.
After all my griping, I do have to give credit where it's due. This phone is much more efficient than my Galaxy Nexus. I left the S5 running in WiFi hotspot mode while on battery last night. It still had over 50% left on the battery. The Galaxy Nexus would be stone dead after about 4 hours. I can live with that if I have to but I'd really rather be able to leave it on the charger at night.
