Increase number of JMS consumers producers by using weblogic properties

Hi All,
I'm looking for an option of increasing the number of JMS consumers in a JMS OSB proxy service. I know that this is possible by modifying the ejb, but I'm looking for any other option by using weblogic/proxy configuration. When I monitor the queue I have a number of 16 message consumers, but I would need to increse it to a higher number in order to improve the performance.
Please send me any suggestion o advice to solve it.
Thanks in advance
Luis

You can associate a work manager with max thread constraints to the proxy service using proxy's dispatch policy configuration. Set a avlue higher than 16 for max threads in the work manager.

WLS 8.1SP4 and the ever-increasing number of JMS connections

We are running a CRM application on a BEA WebLogic 8.1SP4 cluster and we are experiencing some regular performance problems.
When looking at the active JMS connections we see that they can increase till 800 current connections until the application slows down. It takes a very long time to generate the active JMS connections overview
The current number of connections is always nearly identical to the connections high value.
Do you maybe recognize this kind of behavior? Your comments, advice or suggestions are very much appreciated.
With kind regards,
Fred

Configure # of JMS consumers for WebServices over JMS Transport

I'm using WebLogic Server 9.2. My Web Services are using JMS Transport.
10,000 Web Services requests are submitted to the Web Services JMS queue at the same time. Processing time seems a little slow. In the Admin console, monitoring info of the JMS queue shows the Consumers is 4 and Consumers High is 6.
I want to scale Web Services processing by increasing the number of JMS consumers that transform JMS request messages into Web Services requests. Does anyone have an idea to configure it?

Hi,
I don't think the number of consumers for a service is configurable. There is a single consumer for each service. Well, there is another consumer for interop purposes, which is irrelevant to our discussion here.
You may be aware that multiple consumers reading from the same queue would result in requests being processed in parallel, which means the order that the requests are processed might be different from the order that they are put into the queue.
For applications where the order of processing the requests to the same web service is not important, it probably makes sense to have an option of configuring multiple consumers. But this is no such option right now.

JMS consumers and MDBs in free pool

          Hello
          I am using WLS 7.0 SP1. I notice the following when using MDBs listening on
          a JMS queue.
          The WLS console shows the number of JMS consumers to be equal to the <max-free-beans-in-pool>
          parameter value in the MDBs deployment descriptor. I would expect the number of
          JMS consumers to be equal to the <initial-free-beans-in-pool> value before I start
          posting messages to the queue.
          Thanks
          Ramdas


Hi Ramdas,
          I'm fairly sure that this is long-standing behavior, that
          also occurs in 6.1 and 8.1. Since the number of beans
          is limited by the number of available threads, the fact
          that all of them are allocated right away is usually not
          an issue.
          Post to the ejb newsgroup to make sure.
          Tom
          P.S. If you haven't already, I suggest reading
          the most recent version of the JMS performance guide. It
          contains info on tuning MDB threading and pooling. You
          can find the guide on dev2dev.

How to increase number of folders Apple Mail allows.

New folders in Apple Mail are appearing at end of list, rather than alphabetically.
Thanks for any suggestions to increase number of folders allowed.

Deepak,
Check out the following link http://ysislmap.googlecode.com/svn-history/r3/note/siebel/MTServer.txt ..Will help you in configuring Max tasks.
I think you are using workflow policy programs to trigger emails using Email Manager component,if this is the case then it is not a recommended way to create another email manager component running in another siebel server,coz at same time both siebel servers will invoke the component to trigger mails ending you up in receiving two similar mails.

Easy question - how to increase number of recent files in menu?

This is for CS5 if it matters.
I'm an infrequent Illustrator user (at best) but I have what I hope is an easy question: I want to increase number of recent files showing in the menu.
I can't find a preferece to set such as in PS and almost every other application on the face of the earth. I've tried to reset the preferences file (start Illustrator with ctrl-alt-shift held down) but I'm stuck at 4 files, which I assume is the anemic default option.
Is there an easy way to do this that Adobe has hidded somewhere? As expected, it can't be found in the help, I can't find it on the forums, or even on the net, but I do know it can be done because I can see other installs showing lots of files in the list.
thanks for any help.

This might be because of a new feature that you can turn off for each object, and alltogether. When you create a new document at the bottom, make sure 'Align New Objects to Pixel Grid' is unchecked. After you have created a new file, you can still go into the 'TRANSFORM' palette (SHIFT+8), use the little right top menu, and make sure 'Align New Objects to Pixel Grid' is unchecked. And if you want to get fancy with each object; you can select an object, and look at the 'TRANSFORM' palette at the bottom is a place to uncheck the 'Align to Pixel Grid' at your disposall.
Before I found this, it ruined my week.

One of my SQL query having 'in' operator failed saying number of elements exceed.
Is there a limit on number of elements that can be used with - 'in' operator.
And if yes can it be increased?

How increase number of concurent schedule running task?

Hi
Does anyone know, how increase number of concurrent running schedule task?
I was created ten instances of report (as user administrator). They were run every hour on the same time, but only 5 instances have status running on the same time. When one is finish, the next one is going to run.
I don't know where can I increase value concurrent running task.
I use BO XI R2 SP4 on AIX 5.3 TL7
Best Regards,
Krzysztof

With Webi, Webi Job server does "administrative" tasks of scheduling webi reports, they are actualy run by Webi report server.
So be carefull in increasing this value without increasing number of webi report servers !!
There should be XIR2 sizing guide in articles section of this site - review it.

Increasing number of apps not in english

I am a long time user of apple products and iTunes / App Store etc.
Recently I have noticed an increasing number of apps appearing on UK App Store with titles and descriptions in foreign languages and character sets ( ie Chinese)
Naturally I cannot read these ... And what's worse they are cluttering up lists of apps I am looking at, and wasting my time when I open up others that seem ok on the app list, only to find chunks of textual description in say Chinese
Is anyone else getting frustrated by this increasing issue?
Please Apple, get a grip! On the UK sites please at least restrict to English character sets, and preferably perform checks to verify descriptions are in English. If this is not resolved then my visits to the AppStore will decline rapidly .
.. Does anyone else agree?

Oh don't be so daft!
The uk is a multicultural nation speaking in many tongues which is all part of what makes us a great nation
In order to get on we have to communicate via ... Err. Language!
The common language that glues this nation together is English!
The rest if the world and it's languages are on the rise which is just 'evolution', understandable and fine
All I want is to see (or at least be able to filter down to ) apps for the uk written is something that I can understand ...in these busy times I don't want to waste time trawling irrelevant information!!
So.. This request/question is about simple workflow functionality, language and absolutely nothing to do with race whatsoever ever !!!!
Out of interest I work with a very large workforce of Indian professionals from all across India .... Guess what the common language used is ?..... Yup ... English!

Not all JMS consumers are created equal

Hi,
I am experiencing a very strange problem with weblogic 9.2 JMS.
I am using JMS as flow control in an application that allows our users to import data into our application.
the data to be imported varies in size from 100's of records to many hundred thousands of records.
JMS feed a MDB that takes the request and imports the data. The DD allows to 10 concurrent MDB's to service the requests.
The problem arises when the 11'th and 12th request comes in. Instead of waiting for the first availibe MDB to service the requests they seems to be put into the queue of the MDB that was started first. If this MDB is in the process of importing a very large file request 11 and 12 will sit and wait until the large one is done even though there are other MDB's that are idle.
I am hoping that there is an easy fix for this, but for the life of me, I cant seem to find it.
The DD for the MDB looks as follows
<weblogic-enterprise-bean>
<ejb-name>RuleEngineMDB</ejb-name>
<message-driven-descriptor>
<pool>
<max-beans-in-free-pool>10</max-beans-in-free-pool>
<initial-beans-in-free-pool>10</initial-beans-in-free-pool>
</pool>
<destination-jndi-name>com.company.product.RuleEngineRequestQueue</destination-jndi-name>
</message-driven-descriptor>
</weblogic-enterprise-bean>
the queue is defined in Weblog as
<queue name="RuleEngineReque
stQueue">
<sub-deployment-name>MyJMSServer</sub-deployment-name>
<delivery-params-overrides>
<delivery-mode>Non-Persistent</delivery-mode>
</delivery-params-overrides>
<message-logging-params>
<message-logging-enabled>true</message-logging-enabled>
<message-logging-format>%header%,%properties%,%body%</message-logging-format>
</message-logging-params>
<jndi-name>com.company.product.RuleEngineRequestQueue</jndi-name>
</queue>

CTO Compost Marketing AB.

A little more detail: You will need to configure and target a custom conection factory with "message maximum" set to 1 (the default is 10), and then modify the MDB descriptor to reference the JNDI name of the custom connection factory. The connection factory should be targeted to the entire cluster, and must be targeted to the same cluster that hosts distributed queue. If the MDB is transactional, ensure that that the custom connection factory is also "xa enabled".
