How to tune/ decrease loading time of jsff.

Hi All,
I'm using adf 11g.
In my application , one of my transaction scree is taking too much time to load .
In VOimpl i worte / override some method like
executeQuery() to excute the VO query on authorization login base .
and
createRowFromResultSet(Object qc,ResultSet resultSet) to populate the transiet variables on load . 7 -10 parameters are there .
The VO query is running fine and fast when executing in toad.
I have task flow which have search page jsff , default it fetchs records. i have dragged the taskflow to jsf as region.
Please let me know how tune the performance . i have followed this link .
http://www.gebs.ro/blog/oracle/adf-view-object-performance-tuning-analysis/
But this will effect when page load and to retrieve data records.Me getting issue on loading the page itself
Thanks in advance .

Hi,
Before call the page write init method to executeEmptyRowSet() or write customized criteria(ViewCriteria)

How to tune data loading time in BSO using 14 rules files ?

Hello there,
I'm using Hyperion-Essbase-Admin-Services v11.1.1.2 and the BSO Option.
In a nightly process using MAXL i load new data into one Essbase-cube.
In this nightly update process 14 account-members are updated by running 14 rules files one after another.
These rules files connect 14 times by sql-connection to the same oracle database and the same table.
I use this procedure because i cannot load 2 or more data fields using one rules file.
It takes a long time to load up 14 accounts one after other.
Now my Question: How can I minimise this data loading time ?
This is what I found on Oracle Homepage:
What's New
Oracle Essbase V.11.1.1 Release Highlights
Parallel SQL Data Loads- Supports up to 8 rules files via temporary load buffers.
In an Older Thread John said:
As it is version 11 why not use parallel sql loading, you can specify up to 8 load rules to load data in parallel.
Example:
import database AsoSamp.Sample data
connect as TBC identified by 'password'
using multiple rules_file 'rule1','rule2'
to load_buffer_block starting with buffer_id 100
on error write to "error.txt";
But this is for ASO Option only.
Can I use it in my MAXL also for BSO ?? Is there a sample ?
What else is possible to tune up nightly update time ??
Thanks in advance for every tip,
Zeljko

Thanks a lot for your support. I’m just a little confused.
I will use an example to illustrate my problem a bit more clearly.
This is the basic table, in my case a view, which is queried by all 14 rules files:
column1 --- column2 --- column3 --- column4 --- ... ---column n
dim 1 --- dim 2 --- dim 3 --- data1 --- data2 --- data3 --- ... --- data 14
Region -- ID --- Product --- sales --- cogs ---- discounts --- ... --- amount
West --- D1 --- Coffee --- 11001 --- 1,322 --- 10789 --- ... --- 548
West --- D2 --- Tea10 --- 12011 --- 1,325 --- 10548 --- ... --- 589
West --- S1 --- Tea10 --- 14115 --- 1,699 --- 10145 --- ... --- 852
West --- C3 --- Tea10 --- 21053 --- 1,588 --- 10998 --- ... --- 981
East ---- S2 --- Coffee --- 15563 --- 1,458 --- 10991 --- ... --- 876
East ---- D1 --- Tea10 --- 15894 --- 1,664 --- 11615 --- ... --- 156
East ---- D3 --- Coffee --- 19689 --- 1,989 --- 15615 --- ... --- 986
East ---- C1 --- Coffee --- 18897 --- 1,988 --- 11898 --- ... --- 256
East ---- C3 --- Tea10 --- 11699 --- 1,328 --- 12156 --- ... --- 9896
Following 3 out of 14 (load-) rules files to load the data columns into the cube:
Rules File1:
dim 1 --- dim 2 --- dim 3 --- sales --- ignore --- ignore --- ... --- ignore
Rules File2:
dim 1 --- dim 2 --- dim 3 --- ignore --- cogs --- ignore --- ... --- ignore
Rules File14:
dim 1 --- dim 2 --- dim 3 --- ignore --- ignore --- ignore --- ... --- amount
Is the upper table design what GlennS mentioned as a "Data" column concept which only allows a single numeric data value ?
In this case I cant tag two or more columns as “Data fields”. I just can tag one column as “Data field”. Other data fields I have to tag as “ignore fields during data load”. Otherwise, when I validate the rules file, an Error occurs “only one field can contain the Data Field attribute”.
Or may I skip this error massage and just try to tag all 14 fields as “Data fields” and “load data” ?
Please advise.
Am I right that the other way is to reconstruct the table/view (and the rules files) like follows to load all of the data in one pass:
dim 0 --- dim 1 --- dim 2 --- dim 3 --- data
Account --- Region -- ID --- Product --- data
sales --- West --- D1 --- Coffee --- 11001
sales --- West --- D2 --- Tea10 --- 12011
sales --- West --- S1 --- Tea10 --- 14115
sales --- West --- C3 --- Tea10 --- 21053
sales --- East ---- S2 --- Coffee --- 15563
sales --- East ---- D1 --- Tea10 --- 15894
sales --- East ---- D3 --- Coffee --- 19689
sales --- East ---- C1 --- Coffee --- 18897
sales --- East ---- C3 --- Tea10 --- 11699
cogs --- West --- D1 --- Coffee --- 1,322
cogs --- West --- D2 --- Tea10 --- 1,325
cogs --- West --- S1 --- Tea10 --- 1,699
cogs --- West --- C3 --- Tea10 --- 1,588
cogs --- East ---- S2 --- Coffee --- 1,458
cogs --- East ---- D1 --- Tea10 --- 1,664
cogs --- East ---- D3 --- Coffee --- 1,989
cogs --- East ---- C1 --- Coffee --- 1,988
cogs --- East ---- C3 --- Tea10 --- 1,328
discounts --- West --- D1 --- Coffee --- 10789
discounts --- West --- D2 --- Tea10 --- 10548
discounts --- West --- S1 --- Tea10 --- 10145
discounts --- West --- C3 --- Tea10 --- 10998
discounts --- East ---- S2 --- Coffee --- 10991
discounts --- East ---- D1 --- Tea10 --- 11615
discounts --- East ---- D3 --- Coffee --- 15615
discounts --- East ---- C1 --- Coffee --- 11898
discounts --- East ---- C3 --- Tea10 --- 12156
amount --- West --- D1 --- Coffee --- 548
amount --- West --- D2 --- Tea10 --- 589
amount --- West --- S1 --- Tea10 --- 852
amount --- West --- C3 --- Tea10 --- 981
amount --- East ---- S2 --- Coffee --- 876
amount --- East ---- D1 --- Tea10 --- 156
amount --- East ---- D3 --- Coffee --- 986
amount --- East ---- C1 --- Coffee --- 256
amount --- East ---- C3 --- Tea10 --- 9896
And the third way is to adjust the essbase.cfg parameters DLTHREADSPREPARE and DLTHREADSWRITE (and DLSINGLETHREADPERSTAGE)
I just want to be sure that I understand your suggestions.
Many thanks for awesome help,

How to decrease loading time for 0Mat_Plant

Hi Experts,
I am currently looking to decrease loading time of 0Mat_Plant. I have gone thru performance material available and checked following things listed below :
Plz note following:
1) Standard delta is avail but it has been enhanced and there are Z fields. So if i use delta, them I might be missing delta for Field.
2)Can we switch OFF number range SID buffering to avoid memory allocation on daily basis ...somehow through ABAP program?
3) BUffering can be switched OFF, but there is delta load also alonwith full load. So performance would decrease for delta records. But no of records for Full load is 188000 and for delta is just 1700 around. SO will this helps in decreasing overall time? Any idea?
Load is taking around 90 minutes in my system (Full Load)..
I m not clear abt data package size and if it will help me or not..
What more can we do??
Any help would be appreciated and points would be assigned......
Thanks in advance

Hi Nagesh,
Here are my replies;
1) Loading time is only for 0mat_plant..
2) R/3 job finishes quickly....no prob seems to be with this..
3) I m not clear about "locked trfc..but there are no errors in trfc...and there doe snot seem to be IDOC clogging problem...
4) Not sure what yu mean by trfc "released"....
I checked R/3 JOb log and its pasted below ( though for other datasouce)....

I want to confrm my understanding abt extraction process when infopackage gets triggerred...
Infopackge gets triggered....->R/3 job gets created/triggered....-> Info iDoc regarding request sent to BW..-> Application document(??)) posted..(( posted to what???.... passed to Trfc??....and then to psa which is seen in monitor??))...
Like wise after successfull passing of datapackage to BW ( not posting to pSA) , next datapackage is sent..... and so on...
What is TRfc?? .as far I know its function modules created to pass data to bW thru RFC call...(??)...
IF you can give me clear picture of whts happening behind the scenes, it would be great.. or helpful links would do....it would be help me to enjoy wht you ae saying and how to tune more...
THanks for your patience and help...
Already assigned points to you..
PS: I hve turned OFF buffering for master data records greater than 100, 000 and saved approx 25% for each master data records....

I hope it is what you want.

How to improve the load time of my swf group

Hi,
I need help to have some tricks to improve my load time on my swf captivate online traning. My training has 6 sections and it takes 3 minutes to download each time I open the window of the training. It takes too much time and if there are 50 users at the same time, it will take lots of my website bandwidth. Do you have any tips on captivate settings or other tips to help reduce my training download time? I do not understand why the 6 modules loading simultaneously and not every time I click to start a new part of training.
Can you help me with my problem?
Thank you

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.

How to reduce project load time?

I am currently working on a large project (25+ Mb, thousands of vis) with something on the order of 100 classes. Opening the project is painfully slow. It usually takes 7-8 minutes. I'd like to figure out a way to reduce the load time.
What is LV's behavior regarding loading project file vis and libraries (lvlib, lvclass, etc.)?
Are all items in the project automatically loaded when the project is opened?
Are items not in the project but used as sub-vis automatically loaded?
Are dynamically linked items not included in the project automatically opened? (I imagine not.)
Are dynamically linked items that are included in the project automatically opened?
Thanks,
Dave

Hello,
I have talked to multiple people about your issue and we honestly believe that you you are experiencing is expected behavior based on the size of the project and number of VIs used. Creating a new project will sometimes help when a project file has a corruption within it. Since you are experiencing the same behavior on multiple computers, any difference in load time will be a function of the speed, RAM, etc. of that particular computer as compared to your machine. In saying that the files are technically loaded, I am saying that their locations are known so that when they are called, they can be loaded into memory as needed. It does not have to load any portion of the VI other than the location on disk. I would not expect either of those methods to reduce your project load time. Switching to dynamic linking only changes the order in which LabVIEW searches for the files. As I stated before, files added to the project are defined by the name and location on the disk. You can think of the project file as an XML file with different pieces of information about the files. If the file cannot be found, it will try to dynamically link the files by searching for them on the disk. When this happens, it goes through a seris of locations where the files might be located. When the project is loaded, it looks for the files that are listed in the project file first. I hope this helps.

How to find Data load time ?

Hi,
Where do i look for the Total data load time ? from data source to PSA ?

Hi Honar,
1) Goto monitor of IP, in header tab you can find the runtime of IP.
2) So you are loading data from source to BW.In IP header tab copy the req number, goto the source systems from which data is loading.
goto SM37 give the request number with BI as pre-fix, you will find the total run time of job with job log.
Hope this helps.

How to improve jsp load time?

Hi everyone --
Got a question for all of you.
I have a form in a JSP, which does a (Oracle 9i) db lookup on 13 fields and populates the drop-down boxes. The load time for the JSP is slooooww.
These are my options for speeding up the load time (I think):
1. When the web/app server starts the application, have it do all the db lookups and store the resultsets...somewhere. Maybe have some dblistener thread that periodically checks for updates to the db. Then, when someone actually requests the JSP, all the JSP has to do is read the pre-populated drop-down boxes and load.
2. Wait until someone requests the JSP and store all the resultsets as cookies for the session. The resultsets will be good for the home JSP and its sister. This doesn't really solve the problem, since the initial load will still be slow.
3. Combine all the lookup statements into one huge statement, and store the results somewhere. This method queries the db only once, and the drop-down boxes can be populated from one query (instead of 13 separate connections and queries).
All of these ideas seem mediocre to me, and they don't address the fact that the results of the queries change contantly. What I need is a
way to make the JSP load quickly and with the most current information.
Does anyone have any ideas? Which of my suggestions is rather boneheaded?
Thanks for any advice,
-Kwj

It's still not perfect, but it's better at least.
I'm querying 4 different tables overall, and I have a Db class that the jsp instantiates.
from home.jsp:
Db d = new Db();
ResultSet [] all = d.getAll();
<body>
%>
<tr><td align=right>Correspondence ID: </td><td><select>
<option label=""></option>
<%
    rs = all [1];
    while(rs.next()){
%>
        <option><%=rs.getString("sak_correspondence")%></option>
<%
%>
</select></td>
</body>
[\code]
from Db.java:public ResultSet [] getAll() throws SQLException
ResultSet [] all = new ResultSet [4];
all [0] = con.prepareStatement
("select nam_category from doco.corr_category " +
"order by nam_category asc").executeQuery();
all [1] = con.prepareStatement
("select sak_correspondence, dte_received, dte_response_due, " +
"dte_sent, file_path, id_outref, subject " +
"from doco.correspondence").executeQuery();
all [2] = con.prepareStatement
("select nam from doco.corr_type order by nam asc").executeQuery();
all [3] = con.prepareStatement
("select nam_subcategory from doco.corr_subcategory " +
"order by nam_subcategory asc").executeQuery();
return all;
}//getAll()

How to tune the interval time of keyRepeated

Hi, I use keyRepeated to deal some keyboard events. But I want to adjust the frequency of keyRepeated event to be higher/the interval time to be smaller(the default is 100ms), how can I ? Thx

Yes, it's a choice. If j2me can't provide it to u, so do it yourself! :-). Oh, If there is no way to do it surely, I 'll try this way. Thanks for your response.

Loading time of splash screen verus initial siena created splash screen

Hi everyone,
I have a load issue on windows surface RT device with a seina app. I need some insight on trying to decrease load time. This new app has about 2000 images and growing and each image is optimized to be about 20 kb. This app is for reference
when training in specific disciplines. The source is an excel file and the images are downloaded locally when published.
I have two splash screens, the initial splash screen that loads via the default html webpage of the app. The other is a siena screen visual that I call an extended splash screen with the usual timer and rating control. The extended splash screen set
for 2 seconds loads the default settings to be used every time the app loads. The settings are saved to file when the user changes the configuration. This all works are designed.
The app loads within 5-7 seconds on a laptop but takes between 25 - 30 seconds to load on the surface device. I know the initial surface is somewhat slow device but I have tweaked the surface to squeeze every cpu cycle I can during the testing and
analysis stage.
The initial default splash screen takes about 17 - 21 seconds to load. I have tried tweaking as much as possible by removing some visuals on the extended splash screen down to 3, picture, timer, rating. I don't think the extended splash
screen is the issue as this part loads within 7-9 seconds to load.
Can someone explain or provide some insight on the load process during the initial phase on the splash screen, like is the app loading the source data from excel, initializing all the scripts, loading itself into memory, etc... This will allow me to build
more efficient apps with siena.
Thanks,
William

Hi
I cant really give you an technical insight on the load process, but I have noticed that if I have multiple timers and or gallery's (15 +) (I suspect more timers that gallery's) in my app load time was very slow on ARM devices.
Again not sure if this applies to your app but might help point you towards the issue.

Improve Query Suggestions Load time

How can I improve load time for Pre Query Suggestions on search home page when user start typing ??
I notice it was slow in loading when I hit first time in the morning so I try to warm up by adding
""http://SiteName/_api/search/suggest?querytext='sharepoint' ""
in to warm up script but even during the day time after hitting few times it is slower some times . Any reason ?
Do you think moving Query Component to WFE will do any help here?
Pleas let me know - Thanks .

Hi,
Query Suggestions should work at a high level overview is:
• You issue a query within a Search Center site and get results..
• When you hover over or click a result.. this gets stored as a “RecordPageClick” method and will be stored in the Web Applications W3WP process…
• Every five minutes ( I believe ) this W3WP will flush these Recorded Page Clicks and pass them over to the Search Proxy…
• This will then store them in a table in the SSA ( Search Service Application ) Admin DB
• By default, once a day, there is a timer job, Prepare Query Suggestions, that will run
• It does a check to see if the same term has been queried for and clicked at least 6 times and then will move them to another table in the same DB..
• If there are successful queries\clicks > 6 times for a term, and they move to the appropriate table, then when you start to type a word, like “share”
• This will fire a “method” over to the Search proxy servers called “GetQuerySuggestions” and will check that Admin DB to see if they have any matches..
• If so, then it will show up in your Search Box as like “SharePoint” for a suggestion…
Other components involved with the Query Suggestions:
Timer Jobs
Prepare query suggestions                   Daily
Query Classification Dictionary Update for Search Application Search Service Application       Minutes
Query Logging                    Minutes
Database
MSSQLogQuerySuggestion (SearchDB) This gets cleaned up when we run the timer job
MSSQLogQueryString (SearchDB) Info on the Query String
MSSQLogSearchCounts (SearchDB) Info on the click counts
MSSQLogQuerySuggestion Looks like this may be where the hits for suggestions are stored
So the issue might related to timer job, database, connection between SharePoint server and SQL server. There is a similar case caused by DistributedCache.
If you move query component on to another sever, this may improve the process related to Search service, however, it may affect the performance due to networking.
Please collect verbose ULS log per steps below:
Enable Verbose logging via Central Admin> Monitoring> Reporting>Configure diagnostic logging(You can simply set all the categories with Verbose level and I can filter myself).
Reproduce the issue(Try to remove SSRS).
Record the time and get a capture of the error message(including the correlation ID if there is). Collect the log file which is by default located in the folder: <C:\Program files\common files\Microsoft Shared\web server extensions\15\LOGS>.
Stop verbose logging.

Reduce Flex application initial loading time

Comparing to HTML, Flex's initial load time is very long. How
to reduce the initial loading time to the level that is
comparable to HTML's loading time for the page content? Any
best practice or rules to follow?

Ok, OK! What's the specs?
How long is the load time? Please don't say "very long".
Let's see the spec. Oh, and can you give me a load time for the
mythologocal HTML page in question, just so I can compare?
I gotta tell ya, I sometimes take a nap when I'm loading half
the ASP pages I stumble across nowadays.
Here's a page from the Los Angeles times--html--- coming in @
6-7 seconds.
http://latimesblogs.latimes.com/lanow/2009/02/los-angeles-pay.html
Another example: from CNN.com, coming in at about 10-11
seconds. Unbelievable.
http://www.cnn.com/video/#/video/showbiz/2009/02/03/wynter.simpson.scientology.cnn
I've got a 350Kb Flex app using RSLs which loads in about 5
seconds. I'm kicking @ss compared to a lot of professional web
sites out there. Think that's too slow? Compared to what???

Load time problems

http://www.bootleg94.com
anyone have any ideas on how to cut the load time down on the
scrolling image gallery. it takes forever so if anyone has a better
way of doing this and would like to share, please feel free.
=)

Please back up your data ASAP! Your drive is dying and you should make a clone of your system (I use SuperDuper!) before it gives up the ghost entirely. Use a firewire external to clone to, then, when you get a new drive, you can simply reverse clone the data onto it and you'll be up and running.
