Slow response time Java 2 (Standard Edition) v1.4.2_13

Hello all, I'm a new user to Java and not a developer or a programmer, but I thought this forum might be the best place to start seeking answers to my questions.
The organization I work for uses a centralized web-based Oracle (v10g) accounting program to monitor it�s worldwide inventory. Our network has very strong firewalls and uses a lot of security software to insure network integrity. Users navigate to a portal website and login to their account where they post transactions and such. When users login and initiate a session we use Microsoft VM to create the virtual environment where we communicate with the accounting program. Microsoft VM works well in our environment and provides quick GUI response times (seconds) as transactions are posted.
Understanding the real possibility that Microsoft VM might go away in the not so distant future we tried using Java 2 (Standard Edition) v1.4.2_13 (build-B06) to create the virtual environment and connect to our accounts. The response time was incredibly slow, it took minutes for the GUI transition from screen to screen or provide any response to input.
As a test I bypassed our network and used a standard commercial ISP (cable) connection and Java 2 (Standard Edition) v1.4.2_13 (build-B06) to create the virtual environment then logged into my account. The GUI response time I experienced using this connection was very fast.
Our internet browser is IE 6 or better, changing to a different browser is not an otion.
My question is: Are the security settings of our network affecting the system response time when using Java to create the virtual environment? Or could it be something else?
Thanks for your help

RC4 algorithm is patented by RSA Security and it does NOT included into J2SDK 1.4 (there are Blowfish, DES, DESede, PBEWithMD5AndDES and PBEWithMD5AndTripleDE ciphers in SunJCE provider). You can download a free and JDK 1.4 compliant JCE provider with RC4 (and many other ciphers) from http://www.bouncycastle.org/ But keep in mind you may have to pay some royalty if you are going to use it in the production.

Slow response time, applications won't load, etc.

I'm writing this on behalf of my sister, who is on a MacBook Pro, operating Mac OS 10.4.8.
Just yesterday, she began to notice extremely slow response time on her laptop, with applications taking up to 5 minutes to load sometimes, and the Internet subsequently taking ages to switch from page to page. The laptop is also constantly freezing up, with the spinning circle showing up frequently, as well as complete system freezes on and off.
I went on the computer and repaired disk permissions, as well as verified the disk. All went fine. Tried to do a software update in order to update to 10.4.9, but the computer freezes before it can even really begin to download the information.
Numerous reboots were also tried, with nothing working. I don't want to have to do something extreme like reinstalling the operating system without knowing that there might be a simpler solution, so that's why I'm here! I'd also like to know whether we can save her files (documents, etc.), if a reinstallation is needed.
Edit: She reports that she did install or download any software or file attachments, and keeps insisting that the problem virtually came out of nowhere, in case this helps!
Thanks!
MacBook Pro Mac OS X (10.4.9)

Alright-her computer has gotten progressively worse, and has not even managed to reach the log in screen for the past 10 minutes. Just a grey screen, an apple, and the little twirling loading thing.
Am at a loss as to what to do...last night, I could log in, but it was still hanging and taking just about forever for it to do anything.
Is a reformat the only thing left to do? She does subscribe to AppleCare-is it worth calling them, or will they just tell her to reformat as well?
Edit: I'm beginning to think this might date back to a lightning storm we had a couple days ago-does this sort of behaviour seem to follow the behaviour or something that experienced an electrical surge? Her phone in the room was acting funny as well for a few days.

EJB slow response time in cluster

We have 2 clusters : cluster 1(3 managed servers) and cluster2( 2 managed servers). We have an EJB deployed on cluster2 which is being called by an application on cluster1. Issue is that this EJB gives a very slow response time (in the order of minutes). There are no errors or exceptions in the logs.
When we shut down one of the nodes on cluster2, the respose from the same EJB is very fast. Please help as to where we should look out for the issue?

Could be that you have a network configuration problem. The source of the problem is how host names and IP addresses are resolved,
and there is a workaround. RMI and other naming services use the InetAddress class to obtain resolved host names and IP addresses.
InetAddress caches lookup results to improve subsequent calls, but when it is passed a new IP address or host name, it performs a
cross-reference between the IP address and the host name to prevent address spoofing. If you supply the host name as an IP address,
InetAddress still tries to verify the name of the host. To workaround this problem, include the host name and IP address in the
hosts file on the client, for example,
127.0.0.1           localhost
172.30.0.129      SomeWebLogicServerHostName
172.30.0.130      SomeOtherWebLogicServerHostName

Unable to install Java 2 Standard Edition (J2SE) 5.0 Release 4

After Downloading Java 2 Standard Edition (J2SE) 5.0 Release 4
my desktop computer won't recognize the .dmg formatt and this is the messege i get: The following image/disk failed to mount j2Se50Relese4.dmg i have MAC OSX 10.4.6 on a Dual 2 Ghz PowerPC G5. I also have StuffIT expander and it won't recognize it either.

Actually. No, all the problems i've been having has happened with any java downloads with the .dmg formatt all other applications where succefully unstuff.
Your answer is unclear. Can you mount other disk images by double-clicking on their .dmg files? Have you repaired permissions with Disk Utility?
I wonder if it has something to be with the versions of the upgrade. do i need to download them in an expecific order or something?
It depends. Some updates won't be applicable until you install a previous one. For example, some Security Updates won't work unless you an OS update in place.
i currently have install java 1.3.1 plug in and 1.4.2 plug in. i've never open the application thought.
If you mean the Java Plugin Settings.apps for those versions, then that's normal. I have those in addition to the Java Preferences.app from J2SE 5, which I believe is the new name for the settings.app.

Slow response times

This last weekend, we migrated off of our old server 2003 cf7mx server, to a new Server 2008r2 x64 CF 9,0,1,274733 server. We are now experiencing slow response times for our server,according to the Windows Performance monitor our Avg Request times are way up. I have been going through some logs but nothing seems to leap out at me, but i am not the best CF admin. As i dont know what information would be usefull, i have tried to give all the info.

Please let me know if any other data would be usefull.

Hi,
I expect the error details in CF9\runtime\logs\coldfusion-out.log will like provide a clue as to problem.
For a more long term plan I think you should do what you can to migrate the ACCESS data to SQL or some other database.

T400s and T500 experiencing slow response time accessing certain websites from within our network

Hello there.... we have some Lenovo T400s running Windows 7 and T500 running WinXP Pro that are experiencing slow response time when trying to access certain website from within our company network (particularly this global crossing Web meeting, google maps): https://core1.callinfo.com/interface/guest.jsp?host=globalcrossing ... it takes 10-15 minutes before it loads the meeting login screen and same response time for google maps to respond as well... the thing is, other Lenovo T400s, T61, and other HP desktop machines that are connected to the same network in our company does not experience this slow response time... HOWEVER, when these problematic T400s / T500 laptops are connected to external network (e.g. home DSL, hotel DSL/Cable modem) the problem goes away. Our NETWORK ran tests to monitor traffic to the websites from our company's network but seem to connect just fine... just wondering if anybody out there experienced the same problem and know of a solution. By the way, the two newer T400s that are experiencing the slow response time have the following BIOS version 1.11 (6HET26WW) and BIOS version 1.09 (6HET24WW). Then a T400s that is also connected to the same network but not experiencing the problem has a BIOS version of 1.02 (6HET17WW - running WinXP Pro). NOTE: We also connected a Linksys USB wireless adapter to connect to our wireless network in the company but same problem - and problem occurs even when connected via network cable. Your feedback will be greatly appreciated.

Network World posted an article about a free response time monitoring tool that would be worth checking out

Java 2 Standard Edition SDK (Software Development Kit)

Hallo
I bought the Brain Friendly Head First Java Guide. They recommend to install the Java 2 Standard Edition SDK (Software Development Kit) or greater.
I click on Java ME SDK3.2 in the New Downloads menu. I read & accept the license agreement. I then go back to the overview menu option, click on download the system just take me back to accept license agreement page.
What did I do wrong? Please assist me.

Slow Response Time Joining Multiple Domain Indexes

Hi All,
I am working with a schema that has several full text searchable columns along with several other convential columns. I noticed that when I join on 2 Domain Indexes, the response time for query completion nearly doubles. However, If I were to combine my 2 clob columns into 1 clob, the extra cost of finding the intersection of 2 rows sets can be saved..
In my query, I am taking 2 sets of random high probability words (the top 1000 sorted by token_count DESC).
NOTE: All of my query execution times are taken with words not previously used to avoid caching by the engine..
HERE IS THE SLOW VERSION OF THE QUERY WHICH REFERENCES THE BODY CLOB TWICE:
SELECT count(NSS_ID) FROM jk_test_2 WHERE
CONTAINS (body, '( STANDARDS and HELP ) ' ) > 0
AND
CONTAINS (body, '( WORKING and LIMITED ) ' ) > 0 ;

Although the cost is only %15 lower, it executes twice as fast. Also, the same improvement is gained if OR's are used instead of ands:
With --> CONTAINS (BODY,'( ( ( FORM OR GIVE ) and (WEB OR AGREED) ) ') >0
My 2 timings are .25 and .50 with the OR'ed clause above getting the better response time..
BASED ON THIS, On my project I am tempted to merged 2 totally seperate clob columns into 1, to get the better response time. The 2 columns are 1) Body Text and 2) Codes. They LOGICALLY DO NOT BELONG WITH ONE ANOTHER. This would be very ackward for the project as it would cause a lot of fudging of the data in many places throughout the system. I have done this testing taking averages of 500 unique queries, my indexes are up to date with full statistics computed on my tables and indexes. Response time is HIGHLY CRITICAL for this project.
Does anyone have any advice that would allow me to obtain the good response time avoiding the ackwardness of globbing all the data into one clob ?

You might try adding sections and querying using within.

Coherence and EclipseLink - JTA Transaction Manager - slow response times

A colleague and I are updating a transactional web service to use Coherence as an underlying L2 cache. The application has the following characteristics:
Java 1.7
Using Spring Framework 4.0.5
EclipseLink 12.1.2
TopLink grid 12.1.2
Coherence 12.1.2
javax.persistence 12.1.2
The application is split, with a GAR in a WebLogic environment and the actual web service application deployed into IBM WebSphere 8.5.
When we execute a GET from the server for a decently sized piece of data, the response time is roughly 20-25 seconds. From looking into DynaTrace, it appears that we're hitting a brick wall at the "calculateChanges" method within EclipseLink. Looking further, we appear to be having issues with the transaction manager but we're not sure what. If we have a local resource transaction manager, the response time is roughly 500 milliseconds for the exact same request. When the JTA transaction manager is involved, it's 20-25 seconds.
Is there a recommendation on how to configure the transaction manager when incorporating Coherence into a web service application of this type?

Hi Volker/Markus,
Thanks a lot for the response.
Yeah Volker, you are absolutely right. the 10-12 seconds happens when we have not used the transaction for several minutes...Looks like the transactions are moved away from the SAP buffer or something, in a very short time.
and yes, the ABAP WP's are running in Pool 2 (*BASE) and the the JAVA server, I have set up in another memory pool of 7 GB's.
I would say the performance of the JAVA part is much better than the ABAP part.
Should I just remove the ABAP part of the SOLMAN from memory pool 2 and assign the JAVA/ABAP a separate huge memory pool of say like 12-13 GB's.
Will that likely to improve my performance??
No, I have not deactivated RSDB_TDB in TCOLL from daily twice to weekly once on all systems on this box. It is running daily twice right now.
Should I change it to weekly once on all the systems on this box? How is that going to help me?? The only thinng I can think of is that it will save me some CPU utilization, as considerable CPU resources are needed for this program to run.
But my CPU utilization is anyway only like 30 % average. Its a i570 hardware and right now running 5 CPU's.
So you still think I should deactivate this job from daily twice to weekly once on all systems on this box??
Markus, Did you open up any messages with SAP on this issue.?
I remember working on the 3.2 version of soultion manager on change management and the response times very much better than this as compared to 4.0.
Let me know guys and once again..thanks a lot for your help and valuable input.

Slow response time for HTTP requests

I have an 8310 Pearl. For the past week, I've noticed that the response time using the Internet browser was very slow. One work-around was to cancel the request and then submit it again. The second request returned the page MUCH faster.
I cleared my history, and this seemed to have helped. Has anyone else noticed this? Thanks

Welcome to the forums
Try a Battery Pull:
1. Remove the battery while phone is turned on
2. Wait a few seconds before inserting it again
3. Allow the long boot up process to finish (takes a few minutes usually)
This clears most software issues that occur on blackberries from time to time. You could also use Quickpull, a free app that simulates a battery pull without physically removing the battery: http://software.crackberry.com/product.asp?id=27660
A battery pull reclaims memory lost during application usage and clears minor software errors that creep in over time. The blackberry runs an OS just like your PC runs windows and the battery pull is the equivalent of a reboot/restart on your computer.

Experiencing very slow response time using AirPort while wired response is fine. Suggestions?

After a surfing session a few weeks ago the response time for my AirPort internet connection became painfully slow. When I plug in to the wired connection it works fine. Resetting the router and modem doesn't seem to fix it. What might have happened and what can I do to fix it?

It is very possible that you may have some form of Wi-Fi interference that appears during these hours that is preventing your AirPort Base Station from providing a clean RF signal.
I suggest you perform a simple site survey, using utilities like iStumbler, Wi-Fi Explorer or AirRadar to determine potential areas of interference, and then, try to either eliminate or significantly reduce them where possible.

Slow response time on query from one schema to another

I've got two separate databases (one test, the other production). The schemas are pretty much identical and contain the same data. This particular query is executed from .NET (SQL text command, not SP) and takes about 3 seconds when performed against my test db, but takes anywhere from 45 seconds to 5 minutes on the production system. I've exceuted the same statement using Aquadata studio and get the same response times. I didn't build the queries or the schemas, nor do I manage the database servers. But I am responsible for making this work now. These queries have been working in the past, but recently have been changed. I am able to speed this one up with some sql changes, but the others I'm not sure about. I've checked and production db has indexes on the fields I'm querying while the test db does not. I would expect test to be slower, but it's not. Any ideas that I could try. On Monday I'll ask our server admins to check out the server end of it, and see if they need to reboot or something. In the meantime, I'm going to work to revamp the SQL.
Any ideas you can provide would be much appreciated.
Sincerely,
Zam

What causes slow response times

In any session, my computer response times slow down and I have to close all apps and restart to get the system to speed up again. Is this a CPU, hard drive or similar problem? Any solutions?

Hi,
I expect the error details in CF9\runtime\logs\coldfusion-out.log will like provide a clue as to problem.
For a more long term plan I think you should do what you can to migrate the ACCESS data to SQL or some other database.
HTH, Carl.

Slow Response Time on iPhone 3G

On or about r4.0 coming out I started experiencing significant Response Time delays moving between key's on my iPhone and not sure why. I believe this to be a Processor issue... anybody else out there experiencing this issue.
Example:
Select Setting icon on Home Screen... reasonable response time of 1-sec
Select General icon tab... 3-4 sec delay in response
Select another tab on General screen... another 3-4 sec delay before new screen appears.
Hit Home button to close General window... 3-4 sec delay...
Select Messaging icon... goes to white screen and 3-4 sec delay before messaging dialogue screen comes up
Keep in mind that there aren't any other app's running in the background that causes response time delays
The response time delays occur, regardless whether I am on Edge, Wi-fi or 3G.. I do not believe this to be a Networking issue...
Also, I only have 3- menu screens with maybe 23 app icons showing... most of which are iPhone apps like iTunes, Messaging, Settings, Mail, Safari, Stocks, weather, camera, contacts, calendar, pix, Maps, no games!!
I have done master reboot on phone... Network Reset... & Restore...
on rare occasions I will resume a 1-1.5 sec response time between my selections, otherwise, returning to 3-4 sec delays.
Coincidently, around the time this issue occurred, I had upgraded iTunes to 9.2 but doubt this created issues...I eventually downloaded r4.0 thinking a bug fix may have been included... but issue continued...
Any feedback? Thx

Well, to all those queing in on my question-observation... let me provide you an update.
True to form, APPLE provided me great support and Customer Satisfaction.
I did my due diligence and called into Apple Care and an app't was made for me at the Genius Bar the next day.
They assessed my situation and despite informing me it was the nature of the beast (3G), they happily exchanged my 3G out for a new 3G and guess what... with no app's sync'd to it as yet, right out of the box, not r4.0 the response time was the same.
Bottom line is 3G processor's are slow... especially compared against the 3GS and iP4... and loading r4.0 didn't impact it. With my contract expiring in a few days I bit the bullet and have a new iP4 and now enjoy almost instantaneous response to my key selections, etc.... oh, and no dropped calls due to antenna.
