Server deadlocked when trying to reserve a connection

I have domain which has a connection pool with four connections. Under certain circumstances all four connections are in use. A fifth thread comes along, tries to get a connection and causes a deadlock. Question is why doesn't the connection reserve timeout (10 seconds) kick in and break the deadlock ? Is this a bug in WLS ?
I am just curious here. I was able to solve this by increasing the number of connections and also changing a singleton number generator that was involved in the picture. But the root cause appears to be the behaviour of the DataSource.getConnection call. Any info will be appreciated.

Hi, I am using HP11 and iPlanet web server. When trying to upload files over HTTP using FORM ENCTYPE="multipart/form-data" that are bigger than a few Kilobytes i get a 408 error. (client timeout).

Hi, I am using HP11 and iPlanet web server. When trying to upload files over HTTP using FORM ENCTYPE="multipart/form-data" that are bigger than a few Kilobytes i get a 408 error. (client timeout). It is as if the server has decided that the client has timed out during the file upload. The default setting is 30 seconds for AcceptTimeout in the magnus.conf file. This should be ample to get the file across, even increasing this to 2 minutes just produces the same error after 2 minutes. Any help appreciated. Apologies if this is not the correct forum for this, I couldn't see one for iPlanet and Web, many thanks, Kieran.

Hi,
You didnt mention which version of IWS. follow these steps.
(1)Goto Web Server Administration Server, select the server you want to manage.
(2)Select Preference >> Perfomance Tuning.
(3)set HTTP Persistent Connection Timeout to your choice (eg 180 sec for three minutes)
(4) Apply changes and restart the server.
*Setting the timeout to a lower value, however, may prevent the transfer of large files as timeout does not refer to the time that the connection has been idle. For example, if you are using a 2400 baud modem, and the request timeout is set to 180 seconds, then the maximum file size that can be transferred before the connection is closed is 432000 bits (2400 multiplied by 180)

500 internal server error when trying to create users

I am getting a 500 internal server error when trying to create users. What is the cause? We tried reinstalling the latest java jdk release and that didn't help.

Check whether your DBControl or ASControl service is still running or crashed. EM is not able to connect to the Management Server.
For instance in Windows, you may see that the Servise is not started. Then check for error logs in $ORACLE_HOME/sysman/logs for any related error messages in the log files

"500 internal server error" when trying to use F4 help in the variable sele

Hi Experts,
I am getting "500 internal server error" when trying to use F4 help in the variable selection screen (in WAD).
How could this be resolved?
Quick reply would be very helpfull.
Thanks in advance !!

It seems you are using wrong client ID. Make sure your logon pad has right details. You should verify this with your basis team.
If the problem persists then try re-installing. But before you do that you can execute sapbexc.xla which is in the c:\program files\sap\bw. Type c:\ in cell c3 and click "start button". Any red flag means you have wrong version dll/ocx on your local drive, in that case you should reinstall with right patches.
if this solution helps u then pls assign points

Internal Server Error When Trying to Open Flex Builder Tutorials

Anyone know what I need to set up to run the tutorials in
Flex Builder - get an internal error server (500) when trying to
open up the tutorials listed on the start page.
I can open, compile and run projects .
Thanks

well thats a real vague error that IIS can spit out and it
could mean anything. If you are using a server side script in
conjunction with the tutorials for some reason that i would start
by commenting it all out. If you are just getting that error when
just trying to access a static html file that resides whithin your
web root then i would open up IIS and check you permisions under
your default web site for that folder.

Are you using a download manager? Thats will do that to you because most of those don't pick it up that you are logged in to a secure site. They just get the link to download from.
I hope that helps you out although I'm responding very late.

'500 Internal Server Error' when trying to connect to Music Store

Does ANYBODY at Apple CARE that I've been writing posts for 2 WEEKS trying to get an answer to the reason why I can't connect to the Music Store? This is absurd!
Since upgrading to iTunes 6.0.3 (and now 6.0.5), I get a 'Music Store termporarily unavailable' message. I have the same PC, OS, and ISP that I've used to buy hundreds of dollars worth of your music - but since upgrading - I'm dead in the water. Norton is set to PERMIT i-tunes - but I get the same problem with Norton turned OFF.
When trying to connect to the Music Store via the following URL: phobos.apple.com/WebObjects/MZStore.woa/wa/storeFront
as suggested in other posts, I get a "Error 500 Internal Server Error" - which according to my ISP and Microsoft is on APPLE'S Server - not my end.

ResourceException: Access not allowed (when trying to grab a connection from weblogic pool)

I am using WLS7 with SP1.
I just recently migrated from WLS6.0. When my code tries to grab a
connection from the pool, it throws an exception
java.sql.SQLException: Pool connect failed:
weblogic.common.ResourceException: Access not allowed
at weblogic.jdbc.pool.Driver.connect(Driver.java:202)
Does anyone know if anything changed from 6.0 to 7?
Here is a piece of the code that throws exception.
Driver driver =
(Driver)Class.forName("weblogic.jdbc.pool.Driver")
.newInstance();
conn = driver.connect("jdbc:weblogic:pool:" +
dbName, null);
Thanks in advance.

Hi Jung,

Do you know how to change security setting on the connection pool?
Thanks.WebConsole:
1.Compatibility Security => ACLs
Create a new ACL,
name : weblogic.jdbc.connectionPool.yourPoolname
permission : reserve, reset
group : everynone
2.Services => JDBC => Connection Pool
Create a new Connection Pool
ACL Name : weblogic.jdbc.connectionPool.yourPoolname
In 'Target' tab, choose server and click the Apply button

Hi Jung,
Could you try providing weblogic user name and password
in the properties?
Could you also check security setting of the connection pool?

Well that is exactly what I am doing. The variable dbName is database
connection pool name that I created in weblogic console. Again, it
worked
in WLS6 but after migration, it stopped working.

In my code I am supplying name of the connection pool already
created
in
weblogic server. I am asking you to get connection from the pool
using
pool
driver.
In your case you are trying to create connection straight to
database
using pool
driver.
What I am asking is pass name of the connection pool instead of
database
name.
Thanks,

Try As described below:
The following example demonstrates how to use a database
connection
pool
from a servlet.
Load the pool driver and cast it to java.sql.Driver. The
full
pathname
of
the driver is weblogic.jdbc.pool.Driver. For example:
Driver myDriver = (Driver)
Class.forName("weblogic.jdbc.pool.Driver").newInstance();
Create a connection using the URL for the driver, plus
(optionally)
the
name of the registered connection pool. The URL of the pool
driver
is
jdbc:weblogic:pool.
You can identify the pool in either of two ways:
Specify the name of the connection pool in a
java.util.Properties
object
using the key connectionPoolID. For example:
Properties props = new
Properties();props.put("connectionPoolID",
"myConnectionPool");Connection conn =
myDriver.connect("jdbc:weblogic:pool", props);
Add the name of the pool to the end of the URL. In this case
you
do
not
need a Properties object unless you are setting a username
and
password
for using a connection from the pool. For example:
Connection conn =
myDriver.connect("jdbc:weblogic:pool:myConnectionPool",
null);
Note that the Driver.connect() method is used in theseexamples
instead of
the DriverManger.getConnection() method. Although you may
use
DriverManger.getConnection() to obtain a databaseconnection,
we
recommend
that you use Driver.connect() because this method is not
synchronized
and
provides better performance.
Note that the Connection returned by connect() is an
instance
of
weblogic.jdbc.pool.Connection.
Call the close() method on the Connection object when youfinish
with
your
JDBC calls, so that the connection is properly returned to
the
pool. A
good coding practice is to create the connection in a try
block
and
then
close the connection in a finally block, to make sure the
connection
is
closed in all cases.
conn.close();

I am using WLS7 with SP1.
I just recently migrated from WLS6.0. When my code tries

connection from the pool, it throws an exception
java.sql.SQLException: Pool connect failed:
weblogic.common.ResourceException: Access not allowed

Does anyone know if anything changed from 6.0 to 7?
Here is a piece of the code that throws exception.
Driver driver =
(Driver)Class.forName("weblogic.jdbc.pool.Driver")
.newInstance();
conn =
driver.connect("jdbc:weblogic:pool:"

Thanks in advance.
