Fine-tuning the appearance of JFileChooser

I have what I hope is a simple question:
I'm creating a customized JFileChooser. One of the cool things it does is it displays its own custom icons for the files. These icons are a bit bigger than the standard icons for my look-and-feel (Linux default LandF, whatever that is, in Java 1.5). These icons are about 45 pixels high. They look GREAT when viewing in the "icon" view, but when the user switches to the "list" view, they draw on top of eachother. Somehow JFileChooser doesn't know to leave more space.
Any suggestions on this?
And the other question, which I'm sure is a FAQ but I can't find it: I also have a file filter on this JFileChooser, and yet it gives the user the option of changing to "view any file type". Is there a way to turn that off? I really want to constrain what my users are doing.
Thanks

HI,
Remove the select endselect the select all the entries into internal table then from tat internal table select by using for all entries into another internal table. for eq -
IF NOT s_vbeln[] IS INITIAL.
SELECT vbeln cmgst
        INTO TABLE itvbuk
        FROM vbuk
        WHERE vbeln IN s_vbeln.
DELETE itvbuk WHERE cmgst NE 'B' AND cmgst NE 'C' .
ENDIF.
IF NOT itvbuk[] IS INITIAL.
SELECT *
         FROM vbap
         INTO TABLE itvbap
         FOR ALL ENTRIES IN itvbuk
         WHERE vbeln EQ itvbuk-vbeln.
DELETE itvbap WHERE vkgru NE '101' AND NOT vstel IN shp_pt.
ENDIF.
Like wise modify the logic and check the secondary index is available for the where clause which you will be specifing.

Fine tuning the logging to cisco device

Dear Netpro Community,
I am trying to fine tune the AAA portion on the cisco device
Here is my current configuration:
aaa new-model
aaa authentication login default group radius local
aaa authentication enable default group radius enable
If the radius server is offline, the first level is not a problem. However, the issue occurs if I want to go to enable mode. It will not use the enable password defined locally, but instead it will go to and search for radius server for authentication.
Debug:
test_switch>en
Password:
01:05:15: RADIUS: Authenticating using $enab15$
01:05:15: RADIUS: ustruct sharecount=1
01:05:15: RADIUS: Initial Transmit tty0 id 44 x.x.x.x:1812, Access-Request,
len 72
01:05:15: Attribute 4 6 AC10E10F
01:05:15: Attribute 5 6 00000000
01:05:15: Attribute 61 6 00000000
01:05:15: Attribute 1 10 24656E61
01:05:15: Attribute 2 18 69ABFDF8

01:05:35: RADIUS: No response for id 44
01:05:35: RADIUS: No response from server
% Password: timeout expired!
% Error in authentication.
How do I ensure that i can access the switch in privilege mode if there is no path to the radius server?

Jagdeep:
With the default "radius-server retransmit" value, there are (potentially) three retransmissions that may occur if the RADIUS server doesn't respond to the first request. With a 1 sec. "radius-server timeout", this provides a four second window of opportunity for a successful response.
If he doesn't want to use a "radius-server timeout" as low as 1 sec. (per your concern), he can use the "radius-server retransmit" command to constrain (to a reasonable period) the time required to mark an MIA RADIUS Server as dead.
e.g.:
radius-server host aaa.bbb.ccc.ddd auth-port 1812 acct-port 1813 timeout 2 retransmit 1 key xxxxxxxxxx
Contrary to your statement, your approach and mine are trying to facilitate the same thing, i.e.: accommodating fall back to the enable method prior to login timeout.
However, your recommendation only results in a successful login after 20+ sec., due to postponement of fall back, resulting from the 20 sec. spent determining that the MIA RADIUS Server is dead.
I don't ever want to wait 20+ sec. for a login, and don't find it necessary to wait that long to conclude that an AAA server is MIA.

FIne Tuning the Cisco Prime Alarms

HI Expert,
One of our client having Cisco Wireless LAN infrastructure with Cisco Prime. Currently they are getting more alarms (minor) on their environment.
They would like to modify the Alarm pattern / threshold to minimise the Alarms pop-up in prime. Could you please advise me how we can modify this ?
Also do Cisco having any documents for how to fine tune ?
Thank you.
-Ananthan

Hi
Here's the document for the customization of alarms.
Configuring Alarm Severity Levels
A newly generated alarm has a default severity level that you might want to change.
To configure an alarm’s severity level, follow these steps:
Step 1 Choose Administration > System Settings.
Step 2 From the left sidebar menu, choose Severity Configuration.
Step 3 Select the check box of the alarm condition whose severity level that you want to change.
Step 4 From the Configure Security Level drop-down list, choose a severity level, then click Go.
Step 5 Click OK to confirm the changes.

and a.office_code = e.office_code
and d.relationship_code in ('PRI','RET','TTE')is

Is there a more efficient way other than using 2 separate cursors?
I don't want to use the redundant portion as a single cursor since it affects the performance.
Edited by: user9285722 on Apr 1, 2011 4:43 PM

Hi,
Why dont you just use the 1st cursor and along with what you do with the first cursor, if balance!=0 then do what you do with second cursor.
I dont know how you do in pro*c, but here is the algorithm.
open cur_open_act;
loop
-- Do your operations that you do with cursor1.
---Now along with that
IF cur_open_act.balance != 0 then
----- Do your operations that you do with cursor2.
END IF;
end loop;G.

Fine tuning the database query

To analyse the load of a particular object. we do use 'performance analysis' in ABAP. But let us suppose we've come to know that more load is on the database. i.e. suppose 80% on database, 20% on Application server. what could be the possible steps that u wud perform on the query so that the load gets decreased. we don't have a chance to transform the load from database to application server (such as using internal tables and hence reducing the load). we should do something on the database side. so what can we do. any solution would be highly appreciated.
thanks in advance for the solution.

Hi,
You should use ST05 and then Switch TRACE ON for SQL.
Then do your query again.
After you have run your query, you switch the trace OFF and then you display the trace.
When displaying the trace you can see which SQL queries that have been made and how long time they have taken (left most column).
If the time is RED that indicates a bad query.
Anyway. Doubleclick on the query to find out how the query is made.
And analyse the table(s) that are used and whether or not an INDEX is used.
If no index is used you can ADD an index to the database table(s) in transaction SE10. Or directly in the database if you have that possibilty.
ST05,
Trace on,
Run query,
Trace off,
Display trace,
Analyze trace.
Good luck!

How to fine tune the performnce of Adobe - WebDynpro Java

Hi Experts,
Upon deploying an Adobe - WebDynpr Java application on my local NWDW machine having 2 GB RAM, it takes around 10 minutes by watch before the PDF form appears on the screen with the populated data.
This is really depressing as the client will surely not accept this.
Any tips on fine tuning the performance of Adobe online applications?
Regards,
Shobhit

hi,
when the J2EE engine is running...
goto task manager....
see performance.
if the memory usage is more than the memory you have installed,
that means you are using virtual memory...(ie. hard disk as RAM)
try shutting down any excess processes which you are not using.
(CAUTION: shut down only those processes which you know)
Summary is:-
check if you are on virtual memory.
because if you are using virtual memory....
you are falling short of RAM.
our server also has 2 GB RAM, but it works fine(including Interactive forms)

Noise reduction - RAW fine tuning and the Noise Reduction tool

Hi,
1- If I get it right, Aperture's RAW fine tuning "Automatic noise compensation" (translated from French) option uses the camera's information to adjust the noise. Is that correct?
2- The Noise Reduction tool is there to provide additional noise reduction, but this makes you lose some details. Is that correct?
3- How do you use them? I often find the Noise Reduction tool a bit overkill, but that's me.
4- This one is just out of curiosity. How does A3 compare to LR3 beta for you in that regard? In my testing, LR3 did a slightly better job (but A3 totally beats the crap out of LR2 for noise). BUT I have an old D50, and newer cameras handle noise better (especially Nikon), so does it really make a difference for a 2008 or newer camera?
Thanks!

I don't even have this option/checkbox in my Raw Fine Tuning brick.
I wonder if it's due to the type of files (Canon 7D). Do you still have those 7D files I sent you? Does the checkbox appear in Raw Fine Tuning for you with them?
I noticed this option in the manual the other day, but forgot about it until now.
True, it doesn't have the checkbox with the 7D files. However, it as a slider "noise suppression" (again translated) in the RAW fine tuning options (and still has the Noise suppression brick).
If you don't have this one too, have you reprocessed your images with Aperture 3? Since it has a new raw engine, it may be the cause of it.
I find it strange that Apple didn't tout the new RAW engine on Aperture 3 new feature, it clearly is an improvement over Digital Camera RAW 2, especially in noise suppression.
I agree the built-in noise suppression is much better than A2, but IMHO it pales in comparison with the Noise Ninja plugin from Picturecode. The key is that you calibrate a profile for Noise Ninja by shooting a color chart full screen on your computer at varying iso settings with each of your cameras. You then feed the images back in to Aperture, and tell Noise Ninja to create a noise profile for each setting. The results are amazingly good.
Now with a lot of new cameras, noise processing is getting less important because the high iso performance is so good....but this is what makes Noise Ninja special...even when the noise adjustment is subtle, because it is working from a profile created with your camera, at the iso the shot was made at, its effects are seamless. They just announced a 64 bit plugin for Aperture 3, so no bouncing into 32 like other plugins at the moment...

You can try using this tool to first remove all traces of Reader from your computer:
http://labs.adobe.com/downloads/acrobatcleaner.html
Then, you can download the full offline Reader installer from
http://get.adobe.com/reader/enterprise/
After downloading, restart your computer and run the installer before doing anything else.
