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

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.

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

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.

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?

EJB Method Response Time

Hello All,
Is there any way to get the response time (min, max and avg) for each EJB method
call? There was a way to do this BEA Tuxedo, does WLS 7.x provide any way for
such profiling?
Thanks in advance.

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.

Bex input help (F4) very slow response times

When running queries on some of our InfoCubes or ODSs (in 3.5 of 2004s) we are getting a very slow response when using the Input Help (F4) option. We have looked at the article the Nov/Dec 2004 BW Expert and the following SAP Notes 626887, 661251, 626887, 817335, 567746, 581802 and 748623. None of these are of much help. We did not seem to have this problem before the upgrade to 2004s.
Anyone have any other ideas? The users are wanting it fixed.

F4 help behaviour has changed in 04s 3.5 web run time.
See attached thread for a solution (not very helpful in some cases.).

While accessing CDN (tied to blob images) we get this occasional slowness in images loading between 8:00AM to 9:00AM EST. Also we have SiteGuardian tool setup to monitor our page which has CDN Images which reports slowness in getting images.
Sometimes we get slow response:

Response receive time

When things are fine we get a quick response:

application/octet-stream

And sometime it just times out.
What is the best way to trouble shoot such scenario? Is there any logging available if a request fails or if there is slowness in response time? Also, anyway to find out which CDN nodes things are cached at etc?
Thanks in advance.

Hi - Our issue is not yet resolved.
We have CDN connected to Azure Blob Storage Account. We let CDN Heuristics control the caching as our images (blobs) do not have any cache control policy set at this time.
We enabled log and we are seeing such entries, one is below:
1.0;2014-03-07T14:35:43.8958635Z;GetBlob;AnonymousClientOtherError;304;4;4;anonymous;;containername;blob;"http://XXXX.blob.core.windows.net/image1087175937.jpg";"/containername/image1087175937.jpg";abcc2dd9-cf8d-42c5-9e54-7dd9d96a3177;0;65.54.81.147:23347;2009-09-19;696;0;116;0;0;;;;;"If-None-Match=Tuesday,

Are such entries getting logged because of CDN or why do we get these? The IP address is a Microsoft IP.
Based on documentation it seems:
AnonymousClientOtherError
Indicates that the anonymous requests failed precondition checks (like If- Modified etc.) for GET requests.
Examples: Conditional GET requests that fail the check.
Thanks in advance.

Slow response time with terminal emulator

We are using Oracle Financials pkg. 10.7 Character mode using Oracle DB 7.3.3 on a IBM (sequent) S5000 running at DYNIX/ptx 4.2.3 (soon to be 4.2.4). On the end user side, the accounting dept. is connecting to the server using EXTRA Personal Client. During the course of the day, the response time of the emulator slows down. I can count to 25 sometimes b/4 the emulator responds (catches up with the key strokes). Some days it does not happen until the end of the work day and other times it can happen after just a few hours. After checking the network, application and server, we can find nothing wrong. If we have the user reboot their p.c., this seems to clear up the problem. Has anyone else seen or heard of this problem??? If so, does anyone know how to correct it??? We have installed and tried a different emulator that seems to be doing the samething, but only not as bad (slow).
Thanks,

Never heard of this problem or this emulator product.
Oracle did/does have their own emulator that sort of similuates a GUI environment.
It is called OADM (Oracle Display Manager).
If you call support, they may be able to send it to you. However, it's no longer supported, and is a little buggy. But it has no performance problems.
If it straight character feel the users need, Kea TERM works 4 me.
Or, possibly call the your emulators support line.. it could be a known issue with their product..
Most likely it has nothing to do with Oracle products.

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 ;
THE EXPLAIN PLAN shows the intersection being calculated:
| Id | Operation               | Name | Rows | Bytes | Cost (%CPU)| Time |
| 0 | SELECT STATEMENT          |     | 1 | 99 | 3836     (0)| 00:00:47 |
| 1 | SORT AGGREGATE           |     | 1 | 99 |     |     |
| 2 | BITMAP CONVERSION TO ROWIDS     |     | | |     |     |
| 3 | BITMAP AND               |     | | |     |     |
| 4 | BITMAP CONVERSION FROM ROWIDS|     | | |     |     |
| 5 | SORT ORDER BY          |     | | |     |     |
|* 6 | DOMAIN INDEX          | JK_BODY_NDX | | | 1284     (0)| 00:00:16 |
| 7 | BITMAP CONVERSION FROM ROWIDS|     | | |     |     |
| 8 | SORT ORDER BY          |     | | |     |     |
|* 9 | DOMAIN INDEX          | JK_BODY_NDX | | | 2547     (0)| 00:00:31 |
Predicate Information (identified by operation id):
6 - access("CTXSYS"."CONTAINS"("BODY",'( PURCHASE and POSSIBLE)')>0 AND
     "CTXSYS"."CONTAINS"("BODY",'(NATIONAL and OFFICIAL)')>0)
9 - access("CTXSYS"."CONTAINS"("BODY",'(NATIONAL and OFFICIAL)')>0)
I RAN 3 QUERIES and got these times:
Elapsed: 00:00:00.25
Elapsed: 00:00:00.21
Elapsed: 00:00:00.27
HERE IS THE QUERY RE-WRITTEN INTO A DIFFERENT FORMAT WHICH COMBINES THE 2 PARTS INTO 1:
SELECT count(NSS_ID) FROM jk_test_2 WHERE
CONTAINS (body, '( ( STANDARDS and HELP ) AND ( WORKING and LIMITED ) ) ' ) > 0;
The Plan is now:
| Id | Operation     | Name | Rows | Bytes | Cost (%CPU)| Time |
| 0 | SELECT STATEMENT |     | 1 | 99 | 3207     (0)| 00:00:39 |
| 1 | SORT AGGREGATE |     | 1 | 99 |     |     |
|* 2 | DOMAIN INDEX     | JK_BODY_NDX | 5 | 495 | 3207     (0)| 00:00:39 |
Predicate Information (identified by operation id):
2 - access("CTXSYS"."CONTAINS"("BODY",'( ( FORM and GIVE ) AND (WEB and AGREED) ) ')>0)
I RAN 3 QUERIES using new words and got these times:
Elapsed: 00:00:00.12
Elapsed: 00:00:00.11
Elapsed: 00:00:00.13
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.

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.
