How to increase the execution of an application ??

Hi,
i want to increase the time of execution of my Java Application, because it's VERY VERY long ! Just for display a window it tooks 2 minutes !! I have create an executable of my java application with InstallAnyWhere.
Please Help, or my boss will kill me !!
Thanks in advance
Steve

What happens when you write a simple little test frame application like the one below. Does that take 2 minutes to display iteself. If not, then you must be doing some other initialization that is taking so much time.
import javax.swing.*;
public class test extends JFrame
public test()
super( "Test" );
setSize( 200, 200 );
setVisible( true );
public static void main( String args[] )
new test();

How to increase the space of a page in Application Designer ?

Folks,
Hello. I am developing a page in Application Designer.
I need to place multiple records with many fields in the page. But the entire space of the page is not enough to place the fields. We need to use a vertical scroll to increase the space of the page to hold all of the fields. But I don't understand how to do this feature.
Can any folks tell me how to increase the space of a page in Application Designer in order to hold many fields ?

Folks,
Hello. Thanks a lot for replying. It's correct !

Hi,
Many Thanks Charles
Oracle does not recommend using the SORT_AREA_SIZE parameter unless the instance is configured with the shared server option. Oracle recommends that you enable automatic sizing of SQL working areas by setting PGA_AGGREGATE_TARGET instead. SORT_AREA_SIZE is retained for backward compatibility."
--How can i know the instance is configured with the shared server option or not?This might be a tough question to answer. A shared server configuration may be enabled, but the clients may still connect using dedicated sessions, in which case PGA_AGGREGATE_TARGET would still apply.
From
http://download.oracle.com/docs/cd/B19306_01/server.102/b14237/dynviews_2088.htm
V$SESSION includes a column named SERVER which will contain one of the following for each of the sessions: DEDICATED, SHARED, PSEUDO, or NONE. As a quick check, you could query V$SESSION to see if any sessions are connected using a shared server connection.
From:
http://download.oracle.com/docs/cd/B19306_01/server.102/b14231/manproc.htm
There are several parameters which are used to configure shared server support, as well as several views to monitor shared server.
As Robert mentioned, when the WORKAREA_SIZE_POLICY is set to AUTO, the SORT_AREA_SIZE setting is not used, unless a shared server configuration is in use.
--What default value is WORKAREA_SIZE_POLICY and SORT_AREA_SIZE ?From:
http://download.oracle.com/docs/cd/B19306_01/server.102/b14237/initparams157.htm
"Setting PGA_AGGREGATE_TARGET to a nonzero value has the effect of automatically setting the WORKAREA_SIZE_POLICY parameter to AUTO. This means that SQL working areas used by memory-intensive SQL operators (such as sort, group-by, hash-join, bitmap merge, and bitmap create) will be automatically sized. A nonzero value for this parameter is the default since, unless you specify otherwise, Oracle sets it to 20% of the SGA or 10 MB, whichever is greater."
Actually I am facing performence issue since long time till now i did not get the solution even i have raised SRs but i could not.When the issue occur system seems hang.what i monitored whenever hdisk0 and hdisk1 use 100% the issue occur.
Regards,
SajidWhen you say that you have had a performance issue for a long time, is it a performance problem faced by a single SQL statement, a single user, a single application, or everything on the server? If you are able to identify a single user, or SQL statement that is experiencing poor performance, I suggest starting with a 10046 trace at level 8 (wait events) or level 12 (wait events and bind variables) to determine why the execution appears to be slow. If you have not yet determined a specific user or SQL statement that is experiencing performance problems, you might start with either a Statspack Report or an AWR Report (AWR requires a separate license).
If you believe that temp tablespace usage may be a contributing factor to the performance problem, you may want to periodically run this query, which will indicate currently in use temp tablespace usage:
{code}
SELECT /*+ ORDERED */
TU.USERNAME,
S.SID,
S.SERIAL#,
S.SQL_ID,
S.SQL_ADDRESS,
TU.SEGTYPE,
TU.EXTENTS,
TU.BLOCKS,
SQL.SQL_TEXT
FROM
V$TEMPSEG_USAGE TU,
V$SESSION S,
V$SQL SQL
WHERE
TU.SESSION_ADDR=S.SADDR
AND TU.SESSION_NUM=S.SERIAL#
AND S.SQL_ID=SQL.SQL_ID
AND S.SQL_ADDRESS=SQL.ADDRESS;
{code}
The SID and SERIAL# returned by the above could then be used to enable a 10046 trace for a session. The SQL_ID (and CHILD_NUMBER from V$SESSION in recent releases) could be used with DBMS_XPLAN.DISPLAY_CURSOR to return the execution plan for the SQL statement.
You could also take a look in V$SQL_WORKAREA_ACTIVE to determine which, if any, SQL statement are resulting in single-pass, or multi-pass executions, which both access the temp tablespace.

How to increase the number of rows in Status Oveview iView in MSS?

Hi
We have implemented MSS and have a question regarding Status overview iview.
The standard status overview iview of the team workset has 5 rows and we have to scroll using the arrow buttons to select/view a request.
Now can anyone explain me how to increase the number of rows in this iview? Is this somthing that has to be accoplished through web dynpro customization?
I checked the options in iView property and do not see any option to increase the number of rows.
please help
Thanks
-Michael

Hi Micheal,
Well, I am not really sure, if you could accomplish this using customizing, but I am sure that you can accomplish this using the JDI. Well, you can extract the application's source code using JDI and then change the required display rows property and republish it.
Am not really sure if this is suggestable method for this requirement,but it can be achieved using this JDI stuff.

How to increase the number of rows to be displayed in BEx Web Analyzer

hi,
I am viewing reports using BEx Web analyzer option. It is displaying only 24 rows of data at a time. How to increase the number of rows? do i need to any kind of settings?
pls reply.

Hi,
I think the standard template in 2004s is named 0ANALYSIS_PATTERN. You can find it in Web Application Designer, open, and search for the technical name. If you want to change the number of rows or columns, you can find this setting near the bottom of the XHTML view of the template:
<bi:BLOCK_COLUMNS_SIZE value="4" />
<bi:BLOCK_ROWS_SIZE value="17" />
Then just save, and ignore the error messages.

How to increase the battery life of your N series ...

What I am about to post here is valid for any 3G phone or device regardless of model but it is particularly focused towards the N series devices and their power hogging features.
Your battery life is dependant on many many things. How often you take calls on the device, the condition of your battery, the features you use on the device and so on and on. Therefore it is impossible to say that by following the information in this post you will get x amount of days battery life, but it will get you more time out of the battery than you otherwise would have got.
So with that out the way, if your looking to increase your battery life then follow these tips and your battery should start looking a lot healthier.
First of all lets start with THE big one. The one that is going to save you the most juice. Switching 3G off.
Yep, you heard me right. Just by switching the 3G capability of your phone off you will add hours and hours to your battery life. How is this so? Allow me to explain...
Due to the rather poor delivery of 3G in the UK by the network operators, it is rare for any 3G phone to maintain a constant 3G signal. Instead you will find that the phone constantly flips between 3G and GSM mode (Keep an eye on your signal one day). Even those of you on Vodafone who probably have the best 3G network coverage will find this is the case.
Unfortunately, this constant flipping between the two modes sucks power from the battery like a vampire as it alters its reception state for the different modes and the constant flipping is..well...causing it do this constantly! It can sometimes even make your phone unavailable for calls for very brief periods as it trips from GSM to 3G and vice versa.
If you need to use 3G for video calls or whatever then I'm afraid your just going to have to live with this but if you don't (And lets face it few of us do) then you can switch 3G off and increase your battery life considerably.
To do this, go into the "Settings" application (Found in the menu somewhere, by default Nokia normally stick it in "Tools"), and then to the "Phone" tab. In there you will see an option that says "Network mode" and you have a choice of "GSM" or "Dual Mode" (I.e. UMTS and GSM). Set it to GSM and your phone will restart. Once it restarts it will be working in GSM with GPRS speeds only but really for most purposes this is fine.
You have now just extended your battery capability considerably. You can further extend it by going to the "Connection" tab, going into "Packet data" and changing it to "When needed" so it is not constantly checking for a data connection.
The second big change you can make is to turn your phones wifi scanning capability off. The last time I looked not all Nokia's phones that have wifi capability can have their wifi cards switched off entirely but if you can, turn it off except for when you need to use it. Wifi is a power hog.
The next big change you can make is to lower the screen brightness settings on your phone. The less bright your screen is the less power is being used to light it up. Nokia by default leave the screen brightness at something like 50%. Lowering this a bit more will conserve more juice. Before you do this though please consider the fact that lowering the brightness setting will have a big impact on your ability to see the screen clearly in sunny conditions although you will be fine in the dark as you can't lower the brightness that far.
To lower the brightness, go to the settings tool in your phone and into the display option (Hidden in a subcategory called "Personalisation" on the N95). It won't hurt to set the power saving time out to 1 minute and the backlight time out to 10 seconds while your here (Although these are the Nokia default so they should already be set to this).
Finally in regards to the screen, although they may look pretty, animated screensavers use more battery power than the standard blank screen with time and date so avoid them if you can.
It also helps to keep Bluetooth switched off until you need it although the power savings are minimal in comparison to the other changes but every little milliamp counts!
Using the above methods I generally get about 3 to 4 days with about 3 hours talktime on my N95 without using Bluetooth, GPS or anything like that (I might be able to get more but so far I have not paid attention to the battery state before I put it on charge). If I am on a long train journey I can get about 4 hours worth of full screen video and about 2 hours talktime over the period of about 24 hours before it needs a recharge. As I said at the start of the post your mileage will vary greatly depending on how you use your device.
Hope this helps.

no keffa it is a cop out from nokia
its not unfai as its a premium device with a premium price
the n95 battery is atrocious
dont change the post content as the title is 'How to increase the battery life of your N series device'
your talking about nokia phones specifically
the networks are not to blame
they do not make the handsets : Nokia do !!!!!!!!!!
I'm going to choose my words carefully here...
I would never deny the battery on the N95 is not really up to the job of powering the N95 with its power hungry features. To put the same battery into a phone that has WiFi, GPS and a large 320x240 screen, the same one that goes into the E65 which has comparatively nothing compared to it is a bit pants.
However at no point was I criticising them for the band hopping problem. I labelled the post as how to increase the battery life of your N series device because this is a board for the N series devices. It was a simple choice of wording and not intended to be cutting in any way and I did make a remark that the details would be true of any 3G device at the top of the post.
What I was trying to point out in my second post is that the constant band hopping the phone is being forced to do that is draining its battery so much more quicker than it would if it had a constant signal of one kind or another isn't quite Nokia's fault.
They build it to conform to a laid out specification for 3G. However if the network operators cannot be bothered to roll out their 3G infrastructure adequately enough that the phone can find and remain locked onto a 3G signal that is usable then what are Nokia to do other than offer you the capability to turn 3G off until you need it (Although note to Nokia: That **bleep** reboot the phone does when you do this is entirely unneeded and you know it).
Blaming Nokia for this would be like blaming the manufacturer of your radio for failing to pick up radio because the radio station does not have any transmitters within range of your radio's receiver.
Finally...this band hopping is exhibited by all 3G phones built by Samsung, Nokia, Sony Ericsson, etc, from their most budget 3G model to their priciest piece and is the reason that all phones with 3G capabilities have batteries that do not last for any respectable length of time because these phones are also having to band hop between 3G and GSM.
Finally the proof is in the pudding. Turn 3G off for a few days. See your battery improve. Then (Although admittedly this will be harder to do...mcuh harder) find an area where you get a fairly decent 3G signal constantly. Again, see your battery improve. Try it with a different 3G phone...different manufacturer even. The same will be true.
So I stand by my comment, the network operators and their woeful 3G rollout are the villains costing you a fair chunk of your battery and Nokia cannot be expected to mitigate this....but a better battery would be nice all the same...

How to increase the waiting time for response in Adapter Engine not in IE

Hi Experts,
It is a SOAP to Proxy Synchronous interface. SOAP system is sending the request to PI, PI sending the same request to ECC system, After execution of some logic response back to PI in 7 minutes. In ABAP Stack(sxmb_moni) processing the response message also successfully with success flag after completion of these 7 minutes. But exactly 5 minutes later getting the error at Java Stack RWB- in communication channel monitoring i.e
com.sap.engine.interfaces.messaging.api.exception.MessagingException: com.sap.engine.interfaces.messaging.api.exception.MessageExpiredException: Message bd2bf8d0-b2c2-11e0-c383-001cc4fb5cb7(OUTBOUND) expired. We have set the "runtime-HTTP_TIMEOUT" parameter as 3600. thats why in Integration engine it is processing successfully.
kindly suggest me how to increase the waiting time for response in Adapter Engine. Exactly after 5 mins getting the above error in rwb, but in Integration Engine getting successful flag after 7 mins until then it is waiting for response with status flag Log version.

Can any body suggest me how to solve this.....
Thanks in Advance..
Kasi Chukka

Hi Kasi,
Your question is not very clear, from the looks of it, the load on your client's system will be doubling soon.
You need to look at the system stats on how the system is handling the current load, use transactions ST06, ST04 and ST02 to check if the DB hit ratios are as expected, the cpu idle time, the busy periods. Identify if there is large amounts of paging on the server(candidate for increase in real memory).
On AIX level, you will need to look at CPU / Memory usage.
On SAP Application server, you need to look at SAP Buffers.
On Oracle end, look at SGA stats, if it need to increase, the data growth that is current and estimated growth (DB02).
You will not get an exact answer to it, you will need to analyze the existing load and then estimate (guess). The hardware upgrade will also depend on what the client is willing to spend, its always a good practise to add 20% to what you have estimated as these figures are never accurate.
All the best.
Cheers,
Nisch

How to increase the font size in the safari tool bar

Hello,
I am trying to set-up Yosemite for my mom who is a senior. The toolbar and address bar for safari seem to be quite small. Does anyone know how to increase the font size in the tool bar and address bar? I already figured out to make the font size bigger on a webpage which is nice but the rest of the interface, though pleasing to look at, is quite miniscule.
Hope someone can help.

I too would like an easier way to do it. The only way that I have found (& it works for all applications, desktops Document & Download files) is to decrease the size of your Screen display from 2560 by 1440 ( this is your "Default for display") to 1920 by 1080. This is accomplished by going to "Accessibility Preferences" in your menu bar or through Systems Preferences and choosing the DISPLAY icon, then unchecking the "Default for Display" Setting and then check "Scaled".
Your screen resolutions will then appear in the drop down box & you can choose a smaller display (e.g. 1920 x 1440), then all print will appear larger on the screen.
If anyone knows a slicker way, I 'm all ears (actually "eyes" would be more appropriate.
I hope this helps you.

How to increase the performance of an insert query?

Hi,
I am using oracle database for our application where we executes one insert query and need the performance of 300 insert queries to be executed per second.
As of now we are getting only 30/sec.We are not knowing how to tune the database for getting this performance.
we are doing all this though C programming under both linux and solaris environment.
Can u guide me in this issue.
Regards,
vamsi krishna

Performance tuning issue is not something you can get a straight forward answer for.
You need to look at various aspects of the system to get close to or increase the performance of your application. Tuning just the database might not give you want you want.
So, you need to look at the Application codes, Mermory, Disk IO, etc. Have a look at the Performance Tuning Guide from the Oracle Documentation Library for your Oracle Release and Operating System
