Performance Tuning, Threads are waiting to get connection as load increases
Please help.....
We are tuning our application performance. When we do a load test for 300 users we are getting very good response time with few(4 or 5 ) failed transaction and from the weblogic logs I can see The Network Adapter could not get any connection to the database error. When we increase the load to 450 users we see this error a lot and our response time is also very bad. We don't see any issue from the database server. Database server is not overloaded at all. Thread dumps shows up all the threads are in Runnable and waiting to open a socket to establish connection to the database. Please find the dump for one of the thread and most of the threads are doing the same.

Thanks Joe, Thanks for your help. We have passed that problem, but this is what
we are seeing our most of threads are doing. Can you please give any input on this.Good, glad to help. As to your current bottleneck, this is
very likely to be a synchronization (probably needed) in
the hibernate code. Are all these threads trying to do the
same thing, the same ReadAll()? I would investigate whether
1 - You really have to repeat this same operation independently
all the time from lots of threads (eg: can you cache and reuse
data?), and
2 - whether there is a hibernate configuration option that
relaxes the restriction in SoftLimitMRUCache.

I have upgraded to IOS 7 and now I wish I did not as I have lost face time and iMessage and they would not get activated no mater what I have tried .it seems they are trying to get connected but are unable to do so.
It is becoming frustrating to try to get it activated .
I do not know how to get it activated when it keeps informing me that there is no net work connected
Could not sign in please check your network connection and try again.
For both iMessage and FaceTime .
Any radical solution that you have will be appreciated as it is becoming frustrating .First, try a system reset. It cures many ills and it's quick, easy and harmless...
Hold down the on/off switch and the Home button simultaneously until you see the Apple logo. Ignore the "Slide to power off" text if it appears. You will not lose any apps, data, music, movies, settings, etc.
If the Reset doesn't work, try a Restore. Note that it's nowhere near as quick as a Reset. It could take well over an hour! Connect via cable to the computer that you use for sync. From iTunes, select the iPad/iPod and then select the Summary tab. Follow the on-screen directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod. Again, say "yes."
At the end of the basic Restore, you will be asked if you wish to sync the iPad/iPod. As before, say "yes." Note that that sync selection will disappear and the Restore will end if you do not respond within a reasonable time. If that happens, only the apps that are part of the IOS will appear on your device. Corrective action is simple - choose manual "Sync" from the bottom right of iTunes.
If you're unable to do the Restore and you have IOS-6 or lower, go into Recovery Mode per the instructions here. Also, if you have IOS-7, read this. -
Proble with multi-threaded app using the same connection
have a multi-threaded app. The threads all share the
same connection. They all do some selects / updates.
The OS is NT 4.0 and the application server is weblogic
Some times I am getting the error "java.sql.SQLException: Io exception: not in streaming mode"
and some times I am getting "java.sql.SQLException: Io exception: Protocal violation
Any Ideas?
Regards
SureshDon't create threads.... Your threads should if they are necessary be reusable, your threads should call the connections it needs from the cache service with let's say a max number of N pools (each pool a max number of M connections), if the connection domain asked exists on cache a connection is asked for corresponding pool, if the connection domain is not on cache the less used domain is thrown away (all inner connections closed first) and substituted by the new one requested. While the pool is not full keep creating connections as the request came (and all existing connections are being held and not released), when M connections exists, a request should wait till a connection is released.
If you can have 20 threads asking for the same connection and the max number of connections on pool is M=10, then yopur threads will wait for a connection being released. All this must be synchronized. You should set M the closest as possible to the normal number of requests you can imagine to happen the same time. You should get connection use it and release it right away if you can have a lot of requests.
I hope this helps you. -
Looking for book about performance tuning 11g database
Hi,
I am looking for books about performance tuning oracle 11g. The documents from OTN 2 days 11g performance tuning and performance tuning guide are not really study material.
Has someone idea?

Hi
How is it possible to get connection with SAP system when i am working in SAP NetWeaver developer studio?
do i required any connector for this?
RegardsHi Quali,
Inorder to get connected to the SAP system via your SAP NWDS(SAP NetWeaver developer studio).
1) Please check if you are able to get connected to the remote server, incase the server is on a different machine. You can do it by following the steps below:
Click on Windows Start menu -> click on Run -> Typein "cmd" and click on Ok button -> Typein "Ping 'IP address of the remote server'", I mean your remote server machine's IP address(Ex:10.6.52.189 or whatever it is). If it responds then please carry out the following steps in NWDS.
2) Please GoTo :
NWDS menu - > Window -> Preferences -> SAP J2EE Engine(Choose this on the left menu).
Now, if your server is not installed on the same machine on which you are working then go for the first radio button which says "SAP J2EE engine is installed on remote host" and enter the server's IP(Internet Protocol) address(Ex: 10.6.52.14, etc)in "Message Server Host" and enter 3601 in "Message Server Port".
Click on apply and Ok.
3) Now again Click on Windows Start menu -> click on Run -> Typein "drivers" and click on Ok button -> Open the folder "etc" -> look for file "Hosts", openwith notepad
-> Now typein the IP address and the corresponding host name(of the remote server)please note that the IP address and the host name should be separated by at least one space, preferably a tab space. -> save the hosts file.
Now you should be able to connect to your remote server.

My e-mails are not sending. "connection to SMTP server timed out." How do I get this working?
As of yesterday, I am receiving e-mails fine; however, unable to send. Everytime I try to send an e-mail, I get "Sending of message failed. The message could not be sent because the connection to SMTP server (my mail address) timed out. Try again or contact your network administrator.
I received help from lunarpages (they host my domain); however, they were unable to resolve the issue. They suggested something is blocking IP, or need to update Thunderbird, or there's a firewall there...
Help!!!
My clients are waiting for responses to e-mails!
Thank you.To diagnose problems with Thunderbird, try one of the following:
*Restart Thunderbird with add-ons disabled (Thunderbird Safe Mode). On the Help menu, click on "Restart with Add-ons Disabled". If Thunderbird works like normal, there is an Add-on or Theme interfering with normal operations. You will need to re-enable add-ons one at a time until you locate the offender.
*Restart the operating system in '''[http://en.wikipedia.org/wiki/Safe_mode safe mode with Networking]'''. This loads only the very basics needed to start your computer while enabling an Internet connection. Click on your operating system for instructions on how to start in safe mode: [http://windows.microsoft.com/en-us/windows-8/windows-startup-settings-including-safe-mode Windows 8], [http://windows.microsoft.com/en-us/windows/start-computer-safe-mode#start-computer-safe-mode=windows-7 Windows 7], [http://windows.microsoft.com/en-us/windows/start-computer-safe-mode#start-computer-safe-mode=windows-vista Windows Vista], [http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/boot_failsafe.mspx?mfr=true" Windows XP], [http://support.apple.com/kb/ht1564 OSX]
; If safe mode for the operating system fixes the issue, there's other software in your computer that's causing problems. Possibilities include but not limited to: AV scanning, virus/malware, background downloads such as program updates. -
i have taken "Oracle Database 12c: Performance Management and Tuning new" training from oracle university. Now i would like to get certified on "Oracle Database 11g: Performance Tuning 1Z0-054" exam. Is it possible ?
I essentially endorse and refer you to Matthews' and John's post above.
I would differ with slightly with Matthew because my guess is you would often be able to use like for like 12c training for an 11g certification ( I believe there are precedents). BEFORE ANYONE ASKS THE OTHER WAY DOESN'T HAPPEN.
.... but totally concur with Matthew you would ill advised to procede on that basis without one of:
- This being advertised as possible on the website : e.g. https://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=654&get_params=p_id:169 ... option 2 show courses.
- Confirmation from Brandye
- Confirmation from an Oracle Certification Support Web Ticket ( http://education.oracle.com/pls/eval-eddap-dcd/OU_SUPPORT_OCP.home?p_source=OCP )
... The more common (and in my opinion usually better) way would be get your 11g DBA OCP ( or higher first) and then take the 1z0-054. I am almost certain they will accept your 12c course for the 11g DBA OCP.
If you are choosing the route of not being a 11g (or 12c ) DBA OCP first but are on option 2 and relying on the course for certification then the issue is more in the balance and you are even more strongly advised to get confirmation before proceding (remember if the rules need to be changed for you only then any profit out of the exam is lost).
In general my understanding is Oracle would prefer to encourage people to train on the latest version of product that is available for training and will prefer to avoid restrictions which would cause you to train at a lower version. ( This is simply my guess at Oracle University Policy ... personal opinion only).
Having said all I have said I'd encourage you to go with the advice of the earlier two posts. -
Limited threads are created for my databse connection
Hi,
I have my web applicaton running with the mysql as my database. some part of my application has jsps retrieving and displaying some data(I am right now moving the data retrieval part in jsp to bean classes). Till I complete the work on beans I will have my jsps calling the connection and executing the task.
The following is the bean that gets connection to DB
package con;
import java.beans.*;
import java.io.Serializable;
import java.sql.*;
import java.util.*;
public class Myconn extends Object implements Serializable {
public Connection con;
public Connection getConnected() {
connection();
return con;
public void connection()
try
Class.forName("com.mysql.jdbc.Driver");
con = DriverManager.getConnection("jdbc:mysql://localhost:3306/mydb?jdbcCompliantTruncation=false&zeroDateTimeBehavior=convertToNull", "mydb", "data");
catch(SQLException e)
System.out.println(e);
catch(ClassNotFoundException e){
System.out.println("unable to load"+ e);
}The problem is when I check the mysql administrator always it shows only 5 active threads executing 5 queries at an instance(application will be simultaneously used by more than 50 users) also if one thread(which means query) takes more time then it pulls other threads also and this slows down my application.
in my jsps I call the bean as below:
<jsp:useBean id="mycon" class="con.Myconn"/>
Connection connection = mycon.getConnected() ();
statement = connection.createStatement();
.any help on this pleaseYour example was a bit confusing, but here are some tips:
- If you have one database server, yes, running multiple queries on it will probably make each one slower than if only one were running.
- Are you creating a new thread for every query? Try making a thread pool so that you only have X number of queries at once, but none of them need to reconnect, which takes time.
- In the end, you may need to optimize your database.
Can you give a better example of what exactly is going wrong? -
Getting connection toa database in a thread
Hi
I need guidance on how to get connection to a database inside a thread.Let me explain in detail.
I am developing a chat application. As normal my chat server assigns each user an instance of a chathandler class which runs as a thread.The problem is that i need to connect to database inside this thread to implement some group wise logic in the broadcast method of chathandler thread.
Now for this can i create a connection object each time in the thread or can i use a common connection object ? If i go for the second method will it cause any concurrency issue ?
Thanks in advanceHi

the broadcast method of chathandler thread. No, database connections are for persistence. Group wise logic belongs somewhere else.
Now for this can i create a connection object each
time in the thread Yes, for each database access. Create it, use it, close it. Use a connection pool to amortize the cost of opening a connection.
or can i use a common connection object ? If you're foolish you can. How scalable is an app with one connection?
If i go for the second method will it cause
any concurrency issue ?You'll have isolation and concurrency issues to worry about in any case.

Are you waiting to get error message, or are you toggling back and forth?
Just curious of the 'technique' you are using. Are you waiting to get the "network connection was reset" error message or are you just quickly hitting the "i" and "m" keys back and forth?
I've been doing a little bit of both with NO success.I clicked back and forth a couple of times and after the 7th or 8th time I would wait. It finally worked after 30 minutes of doing this. Hope you are up and runnung soon.:)

Got new linksys router WRT160NL , but situation same. Tried reboot, renew lease, forget network, reset network setting. Pls advice
Have you tried a simple reset of your iPod to see if that helps? To do this, press and hold both the Sleep/Wake and Home buttons together long enough for the Apple logo to appear.
Otherwise, have you tried any of the troubleshooting mentioned in this Apple support document?

For over a week,I get the following message everytime I have tried to connect to ITunes Radio..."An error occurred while contacting the radio tuning service. Check your Internet connection, or try again later." My internet connection is excellent & strong & "LATER " has been over a week. Any help or suggestions?? It would be much appreciated, thanks
Somebody suggested clearing the Store cache. I don't know why that would affect the radio. Seems to have not worked for some, worked for a few or maybe they imagined it. Many other posts about this if you browse the forum.
This is happening to some people some of the time in some places, but then not affecting people in other places, or in the same place at different times. You try to guess what is going on. Hasn't happened to me. Maybe it's my iTunes 7.5, or maybe it's luck of the draw since I never use iTunes radio.

Oh, don't expect Apple to say anything about this -- that's not their style.
