WebLogic 10.1 performance

We have been having performance issues on our AIX WebLogic boxes, even when the applications are idle. Does anyone know what WebLogic background processes run behind the scenes or have links to documentation. We want to see if there is something there that's consuming resources (ie, memory).

Hello,
1. Do you have Wily or any monitoring probes / agents associated to the WebLogic JVM?
2. Can you perform a Thread Dump through Admin Console or kill -3 [pid] and see what is running on the background?
Thanks,
Paz

weblogic.developer.interest is a very old newsgroup. About 2 years ago,
we split it into separate newsgroups for each part of the server (ejb,

continued to split even those newsgroups into subgroups: ejb.cmp

WebLogic 8.1: Performance Monitor in AIX 5.2

Can you add the Performance Monitor features to bea (WebLogic 8.1) running in AIX
5.2.
Can you explain in details
If YES, how?
If NO, Why NOT?

Make sure to add dirig.jar in WEBLOGIC_CLASSPATH.

WebLogic RMI UNIX Performance problem

Hi.
I'm experiencing problems with the performance of RMI calls from within session
beans to external RMI services. I have a system running 4 RMI services in separate
JVMs to weblogic 6.1 instance on Solaris 2.6 on SPARC boxes with 1+ Gb of RAM.
The system was developed on NT and deployed to UNIX. A typical request is serviced
in 70-90 ms on the NT development box (Desktop 512Mb RAM) but when deployed to
the UNIX box takes anywhere between 500-4000 ms. Performance metrics in the code
indicate that 'crunch' times are similar but remote RMI calls are orders of magnitude
greater.
Has anybody had similar problems? I have checked the tuning guides wrt TCP/IP
configurations but would not expect such a large difference using the default
Solaris configuration. Memory and CPU utilisation on the SPARC are low as are
I/O and other metrics available from vmstat.
Cheers
Pete

Hi.
The JVMs are running on the same machine thus should be looking in /etc/hosts
and not going via DNS.
I have read there is a performance gain by tying WL to a single CPU, any insight?

worse a reverse lookup. You might want to try using IP addresses in
your config to see if that helps.

Weblogic 5.1 Performance Issue

1. I am having a performence Issue with an application
on Weblogic App server.
2. The application is database intensive, with database operations
for some reports that take few minutes (2 to 5 mins).
The Weblogic thread count properties was set at 15 during this
test.
The JVM max heap size is set to 512 MB.
I am using Oracle thin Driver to connect from my jsp's/ EJB's(Stateless)
to the database.
3. When I simulated 30 users concurrent testing, the application
server is responding very slow. Even pages that do not
require any interaction with the database server (jsp's with
only html tags and no java) take time.
4. During the above test, CPU utilization was low (8%) and java
heap memory utilization was also low (10%).
The Execute Queue length was high (40 to 60) and Execute queue
throughput was low (1 to 5).
6. Subsequent to the above test, I increased the Weblogic thread
count properties to 30 and repeated the test.
The performance has improved little bit but heap memory became
close to 100%.
Can anyone tell what is going wrong?
Would using OCI driver instead of Oracle Thin Driver for this application
result in substantial benefit?

why dont you issue kill -3 on the process and determine what your threads
are doing. You bottleneck will become obvious.
BTW kill -3 gives you a thread dump

Monitor weblogic cluster server performance

I am using "System Monitor" got from http://dev2dev.bea.com/utilitiestools/monitoring.html to monitor my weblogic server performance. For single server, it is working well.
However I can't use it to monitor the cluster server performance. For example:
server 1 and server 2 have clustered weblogic server - APPS listerning on port 8888. On server 1, I have admin server running on server 1 - ADMIN_SVR1 listerning on port 232.
I can dump the admin server Mbean information as:
$java com.iternum.jmx.monitor.SystemMonitor -url t3://localhost:232 -user admin -password xxxxx -mBeanType ExecuteQueueRuntime -of performance.txt
However I can't dump the cluster server performance data as following:
$java com.iternum.jmx.monitor.SystemMonitor -url t3://localhost:8888 -user admin -password xxxxxx -mBeanType ExecuteQueueRuntime -of performance.txt
Did I make any mistake? Do you have better tool to monitor weblogic performance?
Thanks in advance,

WebLogic's High-Performance XML parser

I understand that 6.1's high performance XML parser is the replacement of 6.0's
custom generated parser. Per the documentation, I need to set SAXParserFactory
to weblogic.xml.babel.jaxp.SAXParserFactoryImpl, but I couldn't find weblogic/xml/babel/jaxp/SAXParserFactoryImpl
in either weblogic.jar or xmlx.jar. There are bunch of weblogicx/xml/babel/* in
xmlx.jar.
When I call JAXP code, I got this error:
javax.xml.parsers.FactoryConfigurationError: Failed to find SAXParserFactory.
weblogic.xml.babel.jaxp.SAXParserFactoryImpl
javax.xml.parsers.FactoryConfigurationError: Failed to find SAXParserFactory.
weblogic.xml.babel.jaxp.SAXParserFactoryImpl
Am I missing something, or the 6.1 beta download forget to include the *.babel.jaxp.*
stuff?

Jim,
Please don't use System.setProperty() in any server code. This was intended
as an example only. I think the XMLReaderFactory is not specified in
JAXP1.1.
Thanks,

Jim,
Here is a code fragment to acess the parser:
System.setProperty("javax.xml.parsers.SAXParserFactory","weblogic.xml.babel.
jaxp.SAXParserFactoryImpl");
SAXParserFactory factory = SAXParserFactory.newInstance();
SAXParser parser = factory.newSAXParser();
parser.parse("yourfile.xml",defaultHandler);

I just found out that XML Registry setting on SAXParserFactory does notapply to
XMLReaderFactory() and XMLReader:
XMLReader parser = XMLReaderFactory.createXMLReader();
I have to use SAXParserFactory to get High Performance Parser kicked in:
SAXParserFactory factory = SAXParserFactory.newInstance();
SAXParser parser = factory.newSAXParser();
Is this the right behavior? Thanks for the help.

Thanks for the reply. It still doesn't work. I think the problem is
that weblogic.jar

"weblogicx.xml.babel.jaxp.SAXParserFactoryImpl"
or "weblogic.xml.babel.jaxp.SAXParserFactoryImpl". So the current Beta

forgot to include the above classes. I might try download Beta again
to see if
any difference.

This is a mismatch between our beta and the final place that the

will
live in the release, you should be able to get the parser by setting
the
SAXParserFactory to weblogicx.xml.babel.jaxp.SAXParserFactoryImpl (it
will
be weblogic.xml.babel.jaxp.SAXParserFactoryImpl in the final release).
A couple notes:
The parser only handles standalone documents, with no entityreferences
and
is optimized for small to midsize documents (IE soap and wsdl type
documents).
Pleas let me know if you can get it to work.

WebLogic 6.0 performance on Solaris (Excessive polling)

We have a problem with SunOs 5.8, multi (2) CPU, 1GB memory Weblogic 6.0 sp1 and
java 1.3.0.
While running some benchmarks we realized that the tests run much faster (25%-40%
faster) on a NT Pentium III 800 MHz desktop with 256MB RAM than on our Sun Ultra-250
with the above configuration.
So, we decided to do some profiling by turning on hprof (-X:runhprof:cpu=samples,depth=12)
and realized that over 50% of the time is spent in polling the sockets (weblogic.socket.PosixSocketMuxer.poll).
On NT, only 0.23% time is spent on the same activity. I do not know if on NT WebLogic
uses a different IPC model (select vs. interrupt) but the time taken on Solaris
doing polls is outrageous. I am wondering if anybody else out there has experienced
the same problem? Any insights you have to share on this will be appreciated.
TIA,
-Anil Singhal

The Xprof output is misleading - this does not mean that 50% of
the CPU is spent on polling sockets. It simply means that 50% of the thread samples
were in a polling method (probably waiting, not running).
Yes, I believe that an 800MHz PIII would blow away an ES-250 which runs at less
that 300MHz. So you have 2CPU -> 600MHz. Then
(800-600)/800 = 25% which is what you get.

Weblogic 6.1 performance

Hi,
We are running a weblogic 6.1SP3. We notice every time after running weblogic
server a period of time, we experienced more slow down response from the server.
Those requests will require to retrieve/insert/update data from our oracle database.
Our observation is when more delay caused on user requests, the stateful session
seems to have abnormal handling on the request like swap to do other request during
process one request. We just wonder in what circumstance the stateful bean will
swap like this so frequently? Is there any setting needs to be configured? Like
how to set the priority to do which process first or to avoid the stateful bean
swap to do other request?
By the way, will the problem is caused by the setting of execute Queue? We have
currently set to default value 15, do we need to tune the execute queue to improve
the weblogic performance? Also, will this be the cause on the setting of garbage
collection? Any configuration requires to set? As currently what we will do is
to restart our server after running a few days in order to keep the performance
stable.

Hi,
If you doubt your execute queue is the bottleneck,
you can always monitor it during the performance
test. If the idle threads of the default queue are often
down to 0, your system may need redesign.
Create another queue for your EJB and HTTP requests.
Leave the default queue for the basic I/O and the like.

WebLogic 7 IPlanetAuthenticationProvider Performance

Hello!
I'm trying to use the IPlanteAuthenticationProvider of WLS7 to achieve
authentication and authorization. WLS7 is running on RedHat 7.x on a
P3/400/256MB and IPlanet 5.1 is running on SUN Ultra 10 with Solaris
9.
I get terrible performance of less than 1 successfull authentication
per second. No matter if SSL is used or not. An unrestricted Servlet
can be requested up to about 70 times per second on this hardware...
Does anyone have experience in Performance-Tuning the
IPlanetAuthenticationProvider? Or has anyone written one by himself?
What performance can be achieved?
Thnak you very much!

Weblogic portal propagation performance issue.

Hi,
I created a weblogic portal for client and deployed it on server. After some time we made changes in our portal assests.
I want to reflect these changes on production environment using portal propagation.
I am able to propagate portal assests successfully on production environment using ant script but it takes so much time to propagate.
I have used onlinedownload, offlinecombine, onlineUpload, onlineCommit operation.
src.zip size is 40MB takes 3 hours to dowload, dest.zip size is also of 40MB takes 8hours to dowload.
I have used scoping as well.
I want to reduce propagation time.
For this i read concept of proliferation, but i am not clear that what is the role of proliferation in propagation.
Whether or not proliferation will reduce the Propagation time.
Or is there any way to do this.
Your help will be appreciable.

Hi,
Proliferation refers to the process by which changes made to the Library instance of a portal asset are pushed into user-customized instances of that asset which means that when any changes are made to the portlet in source and if you want to propagate that change to the destination, that time if that portlet is used in a desktop where many users are provided an option to customize that desktop only that particular time at destination if you change the Portal Resources Proliferation of Updates Configuration setting to either Asynchronous or off propagation will be faster because that time propagation utility will not change for each user. If the value is synchronous it changes for each user and hence some delay that too it will happen during commit operation only but not during download operation.
So I feel, Proliferation may not be useful for your case.
We need to find why downloading source is taking 3 hrs and destination is taking 8 hrs.
Please let me know whether you are running downloadsource and downloaddestination.
I suggest run downloadSource in source machine itself and downloadDestination on the destination Machine itself so that you can reduce the network latency.
Thanks & Regards,
Murali.

Java Stored Procedure calling HTTP Servlet in Weblogic

I am currently working on an e-commerce application for a brick-n-mortar electronics store. The store currently has an Oracle database that contains all of the products the store sells. The e-commerce site will have a separate Oracle database. Both database are Oracle 9i release 2 databases. The e-commerce site will be using BEA's Weblogic as its application server. I need to move data from the store db into the e-commerce db. The actual moving of the data is not the issue. The issue comes from needing to call several methods on a Stateless Session EJB, loaded on the Weblogic server, to perform backend processing. I wanted to make a JNDI call from a Java Stored Procedure but with Release 2, this option is no longer supported. The release notes (http://otn.oracle.com/tech/java/htdocs/9idb2_java.html) indicated that the JVM now supports calling out to Servlets using HTTP Client from a Java Stored Procedure.
Has anyone done this? Is there any sample code available?
Thanks for any help.

We have also noticed that other jobs had failed before due to some memory problems,
but using the Weblogic Console; Monitoring; Performance, then when some jobs had
some memory problems forcing the garbage collection the batches worked properly.
Maybe these 2 problems have no relation between one an other, but they appeared
at the same time.
Any help will be appreciated.
Thanks and best regards.

Hi,
We are working with Weblogic 6.1.
The system was quite stable, but a couple of days ago some batch process suddenly
started to fail, with no apparent reason, there was no change in the system neither
in the code.
The following exception is received:
