PreLoad and Execute(Performance)

Hi,
I have been seeing documents which says that we can use the preload and execute in production.
So they really do that.
If so
How does it increase the performance.
Thanks

Just for future reference, the command in the previous post is the absolute correct command. Every other command I have found either opens the "Open With" dialog for every instance, or only works for registered types. Using "rundll32.exe shell32.dll, ShellExec_RunDLL "+file_name pops up the open with dialog when necessary but will open the right application if possible.

Oracle ADF Find and Execute in form

Hi,
I have followed the blog for creating a form which allows for searching. I am executing the Find operation on the viewiterator to enter into query mode at the time of launching the form (in pagephaselistener calling managed bean method and the method executes the OperationBinding.execute to execute the find operation). The view does not have any bind variables, It is a simple view on the table with out any mandatory fields. Then I executed "execute" operation using OperationBinding based on an event in the page by entering the query criteria on the page for a textfield. This is working fine and it is returning the matching records for the query criteria. So far it is good.
http://andrejusb.blogspot.com/2008/09/jdeveloper-11g-crud-in-adf-form.html
But the problem is when there are mandatory fields. My expectation is to execute the query based on the event in the UI even the mandatory fields are not filled. Let us say If the view object is having 4 mandatory columns and the user enters only 1 column it should perform the query and populate the fields. Could you please sugggest.
The behavior should be some thing similar to Oracle forms enter query and execute query modes for the same form fields.
Thanks and Regards,
S R Prasad

You're hitting a bug. See ADF Faces Classical Search Form works only with Entity base VO in JDev 11? for a workaround suggestion.

Long-running transactions and the performance penalty

If I change the orch or scope Transaction Type to "Long Running" and do not create any other transaction scopes inside, I'm getting this warning:
warning X4018: Performance Warning: marking service '***' as a longrunning transaction is not necessary and incurs the performance penalty of an extra commit
I didn't find any description of such penalties.
So my questions to gurus:
Does it create some additional persistence point(s) / commit(s) in LR orchestration/scope?
Where are these persistence points happen, especially in LR orchestration?
Leonid Ganeline [BizTalk MVP] BizTalk Development Architecture

The wording may make it sound so but IMHO, if during the build of an orchestration we get carried away with scope shapes we end up with more persistence points which do affect the performance so one additional should not make soo much of a difference. It
may have been put because of end-user feed back where people may have opted for long running transactions without realizing about performance overheads and in subsequent performance optimization sessions with Microsoft put it on the product enhancement list
as "provide us with an indication if we're to incurr performance penalties". A lot of people design orchestration like they write code (not saying that is a bad thing) where they use the scope shape along the lines of a try catch block and what with
Microsoft marketing Long Running Transactions/Compensation blocks as USP's for BizTalk, people did get carried away into using them without understanding the implications.
Not saying that there is no additional persistence points added but just wondering if adding one is sufficient to warrant the warning. But if I nest enough scope shapes and mark them all as long-running, they may add up.
So when I looked at things other than persistence points, I tried to think on how one might implement the long running transaction (nested, incorporating atomic, etc), would you be able to leverage the .Net transaction object (something the pipeline
use and execute under) or would that model not handle the complexities of the Long Running Transaction which by very definiton span across days/months and keeping .Net Transaction objects active or serialization/de-serialization into operating context will
cause more issues.
Regards.

How to measure query run time and mnitor performance

Hai All,
A simple question. How to measure query run time and mnitor performance? I want to see the parameters like how long it took to execute, how much space it took etc.
Thank you.

hi,
some ways
1. use transaction st03, expert mode.
2. tables rsddstat*
3. install bw statistics (technical content)
there are docs on this, also bi knowledge performance center.

Is there such thing as a "compile and execute statement" in Java?

I wanted to know if there's any way to compile and execute a program "within" another program.

Yes, but the classes to do so aren't officially supported by Sun as far as I know.
And you must be able to assume a thing or two about the stuff you compile, such as existing constructors or factory methods etc, otherwise it gets hairy.
Here's some example code (haven't tried it, so excuse any spelling errors etc) to compile the source code in a file called MyClass.java:
ByteArrayOutputStream baos = new ByteArrayOutputStream();
new sun.tools.javac.Main(baos,null).compile("MyClass.java");
String theMsg = baos.toString();
if (theMsg.length() > 0)
// NiftyErrorHandlingHere
}After that, you can load it with a simple ClassLoader.loadClass() call and create instances of it.
It must be compiled with the tools.jar file in the classpath, to find the sun.tools.javac.Main class.
However, for any such dynamically compiled class to be of any use to you, you must be able to assume something about it, such as implementing interfaces or whatever, otherwise it's a kind of pointless exercise.

Problem with MS Access Files and executable files migrateds

Hi all.
We are migrating an old Netware 6.0 server to new SLES 10 SP3 with OES 2 SP2a. I already migrated one volume and in this weekend well migrate the last, and most important, volume to new OES 2 server.
The problem is about some MS Access databases that are very very used for all users and some executable applications that was writed using fisical path like \\OLDSERVER\VOL\PATH\APP.EXE or some links to libraries, databases, images, etc.
The old NW 6.0 server will be removed from the tree in 2 or 3 weeks and in this time the two servers will co-exists. I want to know if it is possible redirect NCP requests to OLDSERVER to NEWSERVER without users rewrite all of MS Access and executable applications. Is it possible?
Tks

Have you considered trying to use a dns alias to it. I have not tested with
MS access specifically but many other apps it works perfectly for. This is
how I get around those issues. Of course your issue is that you still
havethe existing server in the tree. How much will there still be on the
old server. You could rename the old nw server and than update its info in
dns to resolve this.

PC and Network Performance

Hello:
The City of Detroit is planning to upgrade to 11.03 or 11i. We are looking for network and PC performance minimums/maximums to support as a minimum 11i and any known future upgrades coming but not released. Is there a publication/white paper that would provide information, not only on the above, but would be the expected performance benchmarks for AP, AR, PO, GL, Projects & Grant HRMS, OTA, and FA? At the moment we are on 10.7 and interface with EMPAC. Users are spread over the City in numerous locations. We must assume that the user will have other non-Oracle apps open such as Office and GroupWise.
Thanks,

How to create and execute PL/SQL program or Procedure from Java (JDBC)

hi all,
user will enter the Pl/Sql program from User-Interface. that program has to be create in DB and execute that.
due to some confusions, how to execute this from Java, i (user) entered the same logic through a Procedure.
my Java code is
Statement st = con.createStatement();
Statement.execute(procedure_query); // procedure name is myPro
CallableStatement cs = con.prepareCall("{call myPro}");
(as given in SUN docs - http://java.sun.com/docs/books/tutorial/jdbc/basics/sql.html)
but its not creating the procedure.
and i tried to run a procedure (which is already created) with CallableStatement, and this is also not working.
how to get this.
thanks and regards
pavan

Hi,
SInce the PL/SQL block is keyed in dynamically, you probably want to use the anonymous PL/SQL syntax for invoking it:
// begin ? := func (?, ?); end; -- a result is returned to a variable
CallableStatement cstmt3 =
conn.prepareCall(“begin ? := func3(?, ?); end;”);
// begin proc(?, ?); end; -- Does not return a result
CallableStatement cstmt4 =
Conn.prepareCall(“begin proc4(?, ?); end;”);
SQLJ covered in chapter 10, 11, and 12 of my book furnish a more versatile dynamic SQl or PL/SQL mechanisms.

My solution for: Slow Installs and poor performance

So up until today, most of anyting on XP or even vista 64 ultimate was taking a very long time to install or copy from one part of the drive to another. Startup would grow longer and game performance was dying and only once ever did reinstalling the OS do anything. No matter what I did, nothing would fix the problem.
I ran multiple utilities (disk utility, disk warrior, tech tool deluxe, etc) but none said that there was a hardware problem. But this issue I was having (and I know some of you do) was definitely related to the computer. From my experience, I determined that there was no way this mac was perfect.
So I scheduled a service and repair at my apple store (under warranty). When it was done a few days later, sure enough, I was told that even though the utilities we users can use on our end to diagnose problems didn't find any problems, the hard drive did not pass apple's detailed inspection and was replaced.
In conclusion, I say that if you are having this problem, run disk utility and if you have the extra protection plan, download the Tech Tool Deluxe that apple provides on the support site. Disk utility may find some permission and disk issues but if Tech Tool doesnt find anything even on the surface scan, take it in to the apple store to have a Genius look at it. If it's not under warranty, it's up to you whether or not you want to spend that money. Overall, my computer both on Leopard and XP now runs just as it should.
Hope that helps.

Safari hangs and poor performance in MBPR (Mid 2012)

Safari hangs and poor performance in MBPR (Mid 2012)? OS X 10.10.2 is up to date

Please answer as many of the following questions as you can. You may already have answered some of them. In that case, there's no need to repeat the answers.
Back up all data before making any changes.
Have you restarted your router and your broadband device (if they're separate) since you first noticed the problem? If not, do that now and see whether there's any change.
If your browser is Safari, then from the Safari menu bar, select
Safari ▹ Preferences... ▹ Privacy ▹ Remove All Website Data
and confirm. If the Downloads button (with the icon of a downward-pointing arrow) is showing in the toolbar, click it and then click Clear in the box that appears. The download history will be removed. Any change?
If you're running OS X 10.9 or later, select the Advanced tab in the Preferences window and uncheck the box marked
Stop plug-ins to save power
Any change?
Quit and relaunch the browser. Any change?
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Are any other web browsers installed, and are they the same? What about other Internet applications, such as iTunes and the App Store?
If other browsers and Internet applications are also affected, follow these instructions and test. Any change?
If Parental Controls is active for any user, please turn it off and test. Any change?
If only Safari is affected, launch the Activity Monitor application and enter "web" (without the quotes) in the search box. If a process named "Safari Web Content" is shown in red or is using more than about 5% of a CPU, select it and force it to quit by clicking the X or Quit Process button in the toolbar of the window. There may be more than one such process. Any improvement?
Follow the instructions in this support article. Any change?
Open the iCloud preference pane and uncheck the box marked Photos, if it's checked. Any change?
Are there any other devices on the same network that can browse the Web, and are they affected?
If you can test Safari on another network, is it the same there?
If you connect to your router with Wi-Fi and you can also connect with Ethernet, do that and turn off Wi-Fi. Any difference?

How can i disable a submit button and execute submit_action method on click

Good Day,
On my page I have a submit button that execute the submit_action method of the page backing bean that submit data captured on the page into a database and activate another class that send mail at the same time on a click of the submit button,the mail process takes a while before returning back to the page.I was able to disable the submit button to prevent the user from keep click while the process is running but the issue is on clicking the submit button it only disable the submit button without executing the submit_action method of the page backing bean.How can i disable the submit button and execute submit_method of the backing bean at the same time.
Thanks in advance.

I tried this out on one of my pages to see if it works.
First, I added the following JavaScript to my submit button's onClick event:
this.disabled=true; return true;When I clicked the submit button, it was disabled but the form was not submitted.
I deleted the JavaScript from the onClick event and added the following JavaScript to the form's onSubmit event:
var button = document.getElementById("form1:submitButton"); button.disabled=true; return true;When I click the submit button, it was disabled and the form was submitted but the button's action method was not called.
The next thing I tried was to change the onSubmit event code:
var button = document.getElementById("form1:submitButton"); setTimeout("button.disabled=true", 500); return true;This seemed to work. The difference was that I added a 1/2 second delay before disabling the button.
See if that works for you. If not then I'm fresh out of ideas.

Importing and executing a .sql file into Oracle 10g

Hi
I am looking to import and execute a .sql file(create scripts created of a databse designed in MS SQL Server 2005). The file was imported into Oracle APEX 3.10 but we are unable to execute the script. Please suggest alternatives as to how we can import these files.
Thanks in advance.

You likely need to migrate the database (objects and data). This is not so easy and you should have a look to migration tools: http://www.oracle.com/technology/oramag/oracle/07-sep/o57sql.html.
