Increase of Threads in Managed Nodes
Hi,
I have the following question.
I am analyzing the performance of an Weblogic OSB Cluster in a Production Environment witch is compose by 4 managed servers, with 4 GB of memory each.}
This is the Server Start of each one:
-server -Xms4096m -Xmx4096m -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode -XX:NewSize=512m -XX:MaxNewSize=1536m -XX:PermSize=512m -XX:MaxPermSize=512m -verbose:gc -XX:+PrintGCDetails -Xloggc:/export/home/applsoap/gc_ap1.log -Dweblogic.threadpool.MinPoolSize=150 -Dweblogic.threadpool.MaxPoolSize=340
Nowadays the requests peek during the day is of 15000 Request per minute.
During the day, the Memory of each managed server is around 3GB, and the Threads are around 230 and 280.
I have seen that when threads are increased over 4000 the performance of the system decrease significantly.
We are facing in the following weeks an increase in the request per minute in at least 2 times.
My question is, the parameters of the node that I can see in the Jconsole or in the Oracle Enterprise Manager will be duplicated linearly with this increase?
I mean, I have now 280 Threads with 1500 request per minute?
If I have 3000 request per minute, will I have 560 threads ?
Since I have seen that Up to 400 threads the system is Instable.
I can imagine that the increase will not be linear, but some advice regarding how to measure the performance in the installation will have with
and increase of 2 times the load will be thanked!!!
Thanks you in Advance!
As the name of the method implies the Pool returned by that method supports only a fixed number of threads.
If you want to be able to modify the number of threads after instantiation, then you could use a ThreadPoolExecutor. This class supports changing the number of threads it uses.

Can some one please assist me to get rid of the below error when trying to bring up the SOA services in Weblogic?
"Locker failed to offer due to timeout.Please increase worker thread count by increasing DeferredWorkerThreadCount in mediator-config.xml"
We tested the agent, node manager and everything seems to be working fine. Its persistent in UAT environment which is a clustered environment. 1st managed server for SOA is having the issue while the second one is working fine. Below are the list of manages servers in the env:
2 managed servers for ADF,
2 managed servers for BAM,
2 managed servers for SOA,
2 managed servers for WSM.
The affected SOA1 managed server was working fine till last week and there were no changes made to the environment. Please let me know if I can furnish any further info.

Document Management Node Setup
Should Document Management Node setup be available in 11.5.7 as shown in the Workflow User Guide (pg. 2-31 to 2-33, 4-5 to 4-6, 10-32 to 10-35)? The example in the manual is too generic for my DBA's or Internet people to understand it fully.
If we are using embedded 11i workflows can we attach WORD documents or Excel spreadsheets to workflow notifications in an HP UNIX environment or do we have to be using a formal document image management system?
How do we specifically complete the Document Management Nodes screen for a Document Management system's images?
How do we specifically complete the Document Management Nodes screen for a document created by a PL/SQL procedure?
If we can attach Microsoft office documents to notifications, how do we complete the Document Management Node screen?
We are not using e-mail notifications or e-mail summaries. Users are accessing notification screens only.

The Document Management node setup is reserved for future use.
It is possible to integrate Workflow with Oracle Internet File System and more information can be found at:

Hi,
I have an Item Attribute of Type 'Document' in my WF. When I go to WF monitor to launch this workflow, I see an attachment icon next to this attribute, meaning I can attach a document before launching the wf. But when I click on this icon, it gives a message 'No Document Management Nodes have been defined. Please contact your system administrator.
What does this mean, what settings am I missing, I was going thru the documentation but didn't find anything.
Any help!!

Activating Leave Management Node in 4.7
Hi,
I want to activate the Leave Management subnodes in my 4.7 system.I've alreday activated the BC Set EA-HR.The main Node for LM is visible in SPRO,however the sub nodes are not available,this is because of support pack 1 for EA-HR that I have applied on my system.I can clearly see that this support pack has deleted the tables being accessed under the Leave Management Node.Hence I am unable to view the sub nodes.
Is there any way (maybe another support pack or some configuration) that can bring back my LM functionality??
Please help.
Saba.Dear All,
Come to know how to do that.
Thank you.

Another thing: do NOT compare Strings with == unless you want to check for identity equals (as in the same object). Use String.equals() instead for equality.
Example:
String a = "test";
String b = "test";
String c = new String("test".getBytes());
System.out.println(a.equals(b)); // true
System.out.println(a == b); // true
System.out.println(b.equals(c)); // true
System.out.println(b == c); // falseThis is just a trick from Sun to confuse you ;) String's are internally pooled by the String class. Look at the javadoc of String.intern() for instance for more information. But use String.equals() in your code... -

Calculation manager node not showing up in LCM
Hi Folks,
I am trying to export the Calc manager rules through LCM, I was able to do that in one of our environments, however when I try to perform
this activity in the higher environments, I am unable to find the "Calculation Manager Rules" node node in LCM.
(Shared services->Application groups->Planning-><App Name>-> Plantype-><App name>-> "Calculation Manager Rules" node is missing from here.
Could you guys let me know what do I check between both the environments (the one in which calc manager node is present and one with out) to get this working?If you are trying to export calc manager rules, use Shared services->Calculation Manager node. If you are going against planning, it may be called just rules.

Language Property of KM Repository Manager Node
Hi Community,
i developed a Custom Repository Manager based on the Tutorial form the Code Samples Section.
I have a question regarding to the language of the TREX Search Results. Everything works fine, but the results have some strange languages. I have a german Site wich has the Langugage catalan. I think the Trex decides automatically which langugage the content has.
How can i set the language-attribute in my Repository Manager manually? I tried to set the langugage to German by using the following in the function getProperties in the Node-Class:
SystemPropertyFactory.createContentLanguageProperty("de").
is that the right way?
Greetz MarcusHi,
in order to re-read the config when it is changed you have to implement <b>IConfigListener</b> interface. See my reply in this thread:
<a href="https://www.sdn.sap.com/irj/sdn/thread?threadID=99794">Re: How to read a file(Propeties files) from a respository service - IConfigListener</a>
But I'm not sure that also works effectively with repository managers.
For more info just let me know,

How do I increase the thread limit on Linux?
OS: Linux (or Sun Linux)
Kernel: 2.4.9-31enterprise
Memory: 2GB
CPUs: 2
Java: 1.4.1_01
I have a dual processor Cobalt LX50 and I am running
into a thread limit with Java. No matter what I do
with the Java JVM parameters (heap and stack), I
cannot get any more than 949 threads. My "top" and "vmstat" output
shows that I am no where near my memory capacity.
Below is a simple Java program (28 lines long) I have
used to test this limit. My question is simply how do
I go about increasing this limit. Is there some kernel
parameter I can set or maybe have to recompile into
the kernel? My /proc/sys/kernel/threads-max is 16383.
I do not believe my ulimit settings are the problem,
but I will post them anyway. The problem also occurs
on non-Cobalt (plain old PCs) uniprocessor machines
maxxing at about 1018 threads. The other interesting thing is that when I run the same program through the Kaffe VM with -Xms64M and -Xmx512M I do not run into the thread limit problem. Does anyone know what I need to change to get my thread limit up? Also, rewriting the way the program uses threads is not an option.
[root]# ulimit -a core file size (blocks) 0
data seg size (kbytes) unlimited
file size (blocks) unlimited
max locked memory (kbytes) unlimited

How to increase max thread for SOAP adapter ?
Hi PI Expert,
I have problem with Synchronous SOAP transaction in PI 7.0 EHP1 SPS2. The interface actually using ccBPM.
IDOC ---> ccBPM -
> synchronous call to SOAP adapter.
The problem is there are always timeout call from Integration server to SOAP adapter after several transaction success.
it seems like the soap adapter is doesn't has enough thread to receive call from IS.
the pattern is like success, success, failed, success, success, failed. it always 1 errror within 1 minutes for 4-5 transaction in the same minutes.
is that any log in adapter that i can check or how to increase soap adapter thread ?
Please advise ?

Concurrent Manager Node Name Issue
Hi All,
Recently one of EBS 11i (11.5.10.2 + RHEL 4.7) Node (VM Node) has been cloned to another node. So i had to change the Host name for the cloned application. I followed the meta link note 338003.1 and 341322.1. I am successfully changed the host name and able to access the application as well. When i check the Concurrent manager process's status, its showing Actual-1 and Target -1. B*ut the problem is some of process's node name is showing the previous node name (the name of the node from where cloned).* For example Output Post Processor's node name is showing the previous one and its status showing Actual - 0 and Target - 1. Please let me know why this has happened and also how can i solve this issue?
Thanks,
ManiPlease run cmclean.sql script as per (Concurrent Processing - CMCLEAN.SQL - Non Destructive Script to Clean Concurrent Manager Tables [ID 134007.1]) and check then.
If you still have the same issue, update FND_CONCURRENT_QUEUES table (TARGET_NODE column) -- Troubleshooting the "Error Occurred While Attempting to Establish an Applications File Server Connection" [ID 117012.1]

yeah, good evening.
i finally i found some tim to jeffaeks ;) and i got started with some custome nodes from jim's blog. i appreciate his work, maybe i can contribute some code to the custom node section, too. i am from the deepaMehta project and we are using mainly swing and applets, that's why i got interested in jeffaeks. i hope to find some answers here, cause all the links, mixed up resources and old demos... puuh, these forums here seem to take care about the most active topics...
some small questions are:
a) if i have multiple nodes on my stage, am i able to stop mouse-event-propagation to the nodes/stage/canvas below my clicked node?
b) do you know a panel or a canvas in the packages which already provides mouse-listeners?
c) i want to mask a ImageView, perhaps with a circle but haven't tried yet.i read nile, can export this .. but i don't use nile. could it would work with svgpath or hand-coded, too?
my big question is:
d) how can i handle my "content: Nodes[]" at runtime? (adding/removing). should i slice my nodes into the content sequence of my stage? is this managed with the scenario-scenegraph internally? i am not into that yet, so any hints? i can't just hide them or make them invisible, cause i don't know which type of nodes my user want's to fade (instantiates) into his view.
hopefully my questions are understandable, since i often mixup german grammar and english vocabulary, especcially when it's late :) and here in berlin we have already the 4th...
maybe someone of you can tell me a bit more about those two topics, i would appreciate any hints and tips.
thanks in advance,
malteI think you want to use the Node attribute 'clip'. This clips the boundary of the node (both visual and mouse event wise). The example below shows that mouse events are only sent if the mouse is inside the clip region of a sub node. If you uncomment the clip area on the Group, then it is the union of the Group's clip and the Circles's clip that are used.
package jfx_test;
import javafx.scene.*;
import javafx.input.*;
import javafx.scene.paint.*;
import javafx.application.*;
import javafx.scene.geometry.*;
var fillColor:Color = Color.BLACK;
var clipShape:Shape;
Frame {
width: 200
height: 200
visible: true
stage: Stage {
content: [ Group {
// clip: Rectangle {x: 80, y: 0, width: 40; height: 200 };
content: [ Circle{
centerX: 100
centerY: 100
clip: bind clipShape;
radius: 50
fill: bind fillColor;
Circle{
centerX: 10
centerY: 10
radius: 10
fill: bind fillColor;
onMouseEntered: function(me:MouseEvent):Void {
fillColor = Color.BLUE;
onMouseExited: function(me:MouseEvent):Void {
fillColor = Color.BLACK;
onMouseClicked: function(me:MouseEvent):Void {
if (clipShape == null) {
clipShape = Rectangle {x: 50
y: 80
width: 100
height: 40
} else {
clipShape = null;
}It is interesting to note that changing the clip shape doesn't send a mouse exited event even if the new shape moves the current mouse location outside of the chip area. You do get a mouse exited event as soon as you move the mouse though. -
