Chances for running Java cluster
Hello
I'm working on a multi-user application with expection of 500 users in parallel. Since each user can put a hugh computation load on the machine, I'm thinking about distribution.
I consider the following mechanisms:
* RMI: Natively supported by Java. However, since the application works with generics (classes can be bound / unbound at runtime) and the application can be updated to a new version, even at runtime, dealing with RMI is quite complex and difficult since not only the implementation but also the stub has to be handled. Additionally, since the application is working on one SMP machine after launch (it will take some weeks / month to get maximum number of registered users), RMI will put a burden to the program and takes (expensive) resources.
* XML-RPC: Another approach than RMI, more simple than RMI (since it doesn't require stubs and skeletons). However, even 500 parallel users are active, the system may handle up to 10000 "idle" users. Since my experience with Java and Windows is that there are serious problems with more than 100 open sockets (I don't know the exact number for Linux system), this would mean to have 100 PCs. Well, I want to provide the application from my apartment and it is not really big :)
* Clustering / load balancing: It sounds very interesting to turn multiple machines into one. However, this is more or less "marketing". There are projects available (like MOSIX), that can distribute applications on process level. However, I don't know any system (for Linux) that can distribute on thread level. The only system capable I know (and that is payable) is Amoeba (from Mr. Tanenbaum), however there is no Java support available. In documentation of MOSIX, I read that there are problems with Java if the JRE is using threads by the OS. I don't know in detail, but I'm quite sure that required JRE (I use 1.4 because of java.nio package) is heavily depending on these threads.
Now, the question is: Is there any mechanism to easily load balance a Java program with as least cost as possible. I don't want to charge the users of the application no more than $5 per month :) .
Thank you very much in advance

Smallest OS for running Java runtime?
I have some mother board and memory, but no harddrive. I am just wonder if there is any linux based OS that I can install Java runtime into, and as small as possible? I want it small beacause I want to use compact flash. I think it is a good idea if I can run my java programs on it.
If you know one that is already available, please let me know. If not, I may try to make one myself, and will share others.Well, we (at school) created a linux for cf-flash-cards and it has about 30-40mb, but no graphical interface. With 50-60mb I am sure it would work withought any problems with graphical interface and Java.
But have a look at Knoppix - a linux which runs from CD and should be able to run java withought problems...

instead of the actual name of the program ie. ESR.
Does anybody know why this happens? Is there a way out to ensure that "ps -ef | grep java" gives the actual name of the java program being RUN?
Thanks in advance,
HarishYou have less chance to identify which programm that VM instance is running right now.
But you could (as we do) keep track of your programs if you save the process-id when you start the program.
We need this to shut down running java batch programs but you could find out the used system resources with this way as well... -

hello...
does anyone know the JSP codes for running a Java program from my web page?? i mean i already have my java program compiled... and i just want this java program to run in the background when I click on a button or a link...
Any idea about this?
plz advice..
aviyes... u r somewhat right... but this runs on Jakarta Tomcat...
i'm using the Apache Http Server together with the ServletExec AS which enable the Apache server to run JSP..
I've created a package where i've put my classes...

and i've added.. package name.. in my java program..
and then in jsp... i've written..
<%@ page import="tdb.*"%>

Problem with Configuring Tomcat for running jsp web applications..Plz HELP
I am using Tomcat 5.5 and Jdk 1.5.0_12 and Oracle 10g. I am using jdbc-odbc bridge connection
to connect to the database. I have placed my project folder called
tdm under the webapps folder in Tomcat. This 'tdm' folder consists of
a collection of html pages,jsp pages and images of my project. Also I created a
WEB-INF folderand in that I have lib folder which contains catalina-root.jar
, classes12.jar and nls_charset.jar files. And also in the WEB-INF folder I have the web.xml
file which looks like this

You can also enable an SSL HTTP/1.1 Connector on port 8443 by
following the instructions below and uncommenting the second Connector
entry. SSL support requires the following steps (see the SSL Config
HOWTO in the Tomcat 5 documentation bundle for more detailed
instructions):
* If your JDK version 1.3 or prior, download and install JSSE 1.0.2 or
later, and put the JAR files into "$JAVA_HOME/jre/lib/ext".
* Execute:
%JAVA_HOME%\bin\keytool -genkey -alias tomcat -keyalg RSA (Windows)
$JAVA_HOME/bin/keytool -genkey -alias tomcat -keyalg RSA (Unix)
with a password value of "changeit" for both the certificate and
the keystore itself.
By default, DNS lookups are enabled when a web application calls
request.getRemoteHost(). This can have an adverse impact on
performance, so you can disable it by setting the
"enableLookups" attribute to "false". When DNS lookups are disabled,
request.getRemoteHost() will return the String version of the
IP address of the remote client.

<!-- Defines a cluster for this node,
By defining this element, means that every manager will be changed.
So when running a cluster, only make sure that you have webapps in there
that need to be clustered and remove the other ones.
A cluster has the following parameters:
className = the fully qualified name of the cluster class
name = a descriptive name for your cluster, can be anything
mcastAddr = the multicast address, has to be the same for all the nodes
mcastPort = the multicast port, has to be the same for all the nodes
mcastBindAddr = bind the multicast socket to a specific address
mcastTTL = the multicast TTL if you want to limit your broadcast
mcastSoTimeout = the multicast readtimeout
mcastFrequency = the number of milliseconds in between sending a "I'm alive" heartbeat
mcastDropTime = the number a milliseconds before a node is considered "dead" if no heartbeat is received
tcpThreadCount = the number of threads to handle incoming replication requests, optimal would be the same amount of threads as nodes
tcpListenAddress = the listen address (bind address) for TCP cluster request on this host,
in case of multiple ethernet cards.
auto means that address becomes
InetAddress.getLocalHost().getHostAddress()
tcpListenPort = the tcp listen port
tcpSelectorTimeout = the timeout (ms) for the Selector.select() method in case the OS
has a wakup bug in java.nio. Set to 0 for no timeout
printToScreen = true means that managers will also print to std.out
expireSessionsOnShutdown = true means that
useDirtyFlag = true means that we only replicate a session after setAttribute,removeAttribute has been called.
false means to replicate the session after each request.
false means that replication would work for the following piece of code: (only for SimpleTcpReplicationManager)
<%
HashMap map = (HashMap)session.getAttribute("map");
map.put("key","value");
%>
replicationMode = can be either 'pooled', 'synchronous' or 'asynchronous'.
* Pooled means that the replication happens using several sockets in a synchronous way. Ie, the data gets replicated, then the request return. This is the same as the 'synchronous' setting except it uses a pool of sockets, hence it is multithreaded. This is the fastest and safest configuration. To use this, also increase the nr of tcp threads that you have dealing with replication.
* Synchronous means that the thread that executes the request, is also the
thread the replicates the data to the other nodes, and will not return until all
nodes have received the information.
* Asynchronous means that there is a specific 'sender' thread for each cluster node,
so the request thread will queue the replication request into a "smart" queue,
and then return to the client.
The "smart" queue is a queue where when a session is added to the queue, and the same session
already exists in the queue from a previous request, that session will be replaced
in the queue instead of replicating two requests. This almost never happens, unless there is a
large network delay.
-->
<!--
When configuring for clustering, you also add in a valve to catch all the requests
coming in, at the end of the request, the session may or may not be replicated.
A session is replicated if and only if all the conditions are met:
1. useDirtyFlag is true or setAttribute or removeAttribute has been called AND
2. a session exists (has been created)
3. the request is not trapped by the "filter" attribute
The filter attribute is to filter out requests that could not modify the session,
hence we don't replicate the session after the end of this request.
The filter is negative, ie, anything you put in the filter, you mean to filter out,
ie, no replication will be done on requests that match one of the filters.
The filter attribute is delimited by ;, so you can't escape out ; even if you wanted to.
filter=".*\.gif;.*\.js;" means that we will not replicate the session after requests with the URI
ending with .gif and .js are intercepted.
The deployer element can be used to deploy apps cluster wide.
Currently the deployment only deploys/undeploys to working members in the cluster
so no WARs are copied upons startup of a broken node.
The deployer watches a directory (watchDir) for WAR files when watchEnabled="true"
When a new war file is added the war gets deployed to the local instance,
and then deployed to the other instances in the cluster.
When a war file is deleted from the watchDir the war is undeployed locally
and cluster wide

I have set the context path to /tdm in the server.xml file. Should this be placed in context.xml?
My first page in the project is called Homepage.html. To start my project I give http://localhost:5050/tdm/homepage.html
in a browser. Here I accept a username and password from the user and then do the validation in
a valid.jsp file, where I connect to the database and check and use jsp:forward to go to next pages
accordingly. However when I enter the username and password and click Go in the homepage, nothing is
displayed on the next page. The URL in the browser says valid.jsp but a blank screen appears.
WHY DOES IT HAPPEN SO? DOES IT MEAN THAT TOMCAT IS NOT RECOGNIZING JAVA IN MY SYSTEM OR IS IT A PROBLEM
WITH THE DATABASE CONNECTION OR SOMETHING ELSE? I FEEL THAT TOMCAT IS NOT EXECUTING JSP COMMANDS?
IS IT POSSIBLE?WHY WILL THIS HAPPEN?
I set the JAVA_HOME and CATALINA_HOME environment to the jdk and tomcat folders resp.
Is there any other thing that I need to set in classpath? Should I have my project as a
WAR file in the webapps of TOMCAT or just a folder i.e. directory structure will fine?I am using Tomcat 5.5 and Jdk 1.5.0_12 and Oracle 10g. I am using jdbc-odbc bridge connection

define subcomponents such as "Valves" or "Loggers" at this level.

<!-- A "Connector" represents an endpoint by which requests are received
and responses are returned. Each Connector passes requests on to the
associated "Container" (normally an Engine) for processing.
By default, a non-SSL HTTP/1.1 Connector is established on port 8080.
You can also enable an SSL HTTP/1.1 Connector on port 8443 by
following the instructions below and uncommenting the second Connector
entry. SSL support requires the following steps (see the SSL Config
HOWTO in the Tomcat 5 documentation bundle for more detailed
instructions):
* If your JDK version 1.3 or prior, download and install JSSE 1.0.2 or
later, and put the JAR files into "$JAVA_HOME/jre/lib/ext".
* Execute:
%JAVA_HOME%\bin\keytool -genkey -alias tomcat -keyalg RSA (Windows)
$JAVA_HOME/bin/keytool -genkey -alias tomcat -keyalg RSA (Unix)
with a password value of "changeit" for both the certificate and
the keystore itself.
By default, DNS lookups are enabled when a web application calls
request.getRemoteHost(). This can have an adverse impact on
performance, so you can disable it by setting the
"enableLookups" attribute to "false". When DNS lookups are disabled,
request.getRemoteHost() will return the String version of the
IP address of the remote client.

<!-- Defines a cluster for this node,
By defining this element, means that every manager will be changed.
So when running a cluster, only make sure that you have webapps in there
that need to be clustered and remove the other ones.
A cluster has the following parameters:
className = the fully qualified name of the cluster class
name = a descriptive name for your cluster, can be anything
mcastAddr = the multicast address, has to be the same for all the nodes
mcastPort = the multicast port, has to be the same for all the nodes
mcastBindAddr = bind the multicast socket to a specific address
mcastTTL = the multicast TTL if you want to limit your broadcast
mcastSoTimeout = the multicast readtimeout
mcastFrequency = the number of milliseconds in between sending a "I'm alive" heartbeat
mcastDropTime = the number a milliseconds before a node is considered "dead" if no heartbeat is received
tcpThreadCount = the number of threads to handle incoming replication requests, optimal would be the same amount of threads as nodes
tcpListenAddress = the listen address (bind address) for TCP cluster request on this host,
in case of multiple ethernet cards.
auto means that address becomes
InetAddress.getLocalHost().getHostAddress()
tcpListenPort = the tcp listen port
tcpSelectorTimeout = the timeout (ms) for the Selector.select() method in case the OS
has a wakup bug in java.nio. Set to 0 for no timeout
printToScreen = true means that managers will also print to std.out
expireSessionsOnShutdown = true means that
useDirtyFlag = true means that we only replicate a session after setAttribute,removeAttribute has been called.
false means to replicate the session after each request.
false means that replication would work for the following piece of code: (only for SimpleTcpReplicationManager)
<%
HashMap map = (HashMap)session.getAttribute("map");
map.put("key","value");
%>
replicationMode = can be either 'pooled', 'synchronous' or 'asynchronous'.
* Pooled means that the replication happens using several sockets in a synchronous way. Ie, the data gets replicated, then the request return. This is the same as the 'synchronous' setting except it uses a pool of sockets, hence it is multithreaded. This is the fastest and safest configuration. To use this, also increase the nr of tcp threads that you have dealing with replication.
* Synchronous means that the thread that executes the request, is also the
thread the replicates the data to the other nodes, and will not return until all
nodes have received the information.
* Asynchronous means that there is a specific 'sender' thread for each cluster node,
so the request thread will queue the replication request into a "smart" queue,
and then return to the client.
The "smart" queue is a queue where when a session is added to the queue, and the same session
already exists in the queue from a previous request, that session will be replaced
in the queue instead of replicating two requests. This almost never happens, unless there is a
large network delay.
-->
<!--
When configuring for clustering, you also add in a valve to catch all the requests
coming in, at the end of the request, the session may or may not be replicated.
A session is replicated if and only if all the conditions are met:
1. useDirtyFlag is true or setAttribute or removeAttribute has been called AND
2. a session exists (has been created)
3. the request is not trapped by the "filter" attribute
The filter attribute is to filter out requests that could not modify the session,
hence we don't replicate the session after the end of this request.
The filter is negative, ie, anything you put in the filter, you mean to filter out,
ie, no replication will be done on requests that match one of the filters.
The filter attribute is delimited by ;, so you can't escape out ; even if you wanted to.
filter=".*\.gif;.*\.js;" means that we will not replicate the session after requests with the URI
ending with .gif and .js are intercepted.
The deployer element can be used to deploy apps cluster wide.
Currently the deployment only deploys/undeploys to working members in the cluster
so no WARs are copied upons startup of a broken node.
The deployer watches a directory (watchDir) for WAR files when watchEnabled="true"
When a new war file is added the war gets deployed to the local instance,
and then deployed to the other instances in the cluster.
When a war file is deleted from the watchDir the war is undeployed locally
and cluster wide

I have set the context path to /tdm in the server.xml file. Should this be placed in context.xml?
My first page in the project is called Homepage.html. To start my project I give http://localhost:5050/tdm/homepage.html
in a browser. Here I accept a username and password from the user and then do the validation in
a valid.jsp file, where I connect to the database and check and use jsp:forward to go to next pages
accordingly. However when I enter the username and password and click Go in the homepage, nothing is
displayed on the next page. The URL in the browser says valid.jsp but a blank screen appears.
WHY DOES IT HAPPEN SO? DOES IT MEAN THAT TOMCAT IS NOT RECOGNIZING JAVA IN MY SYSTEM OR IS IT A PROBLEM
WITH THE DATABASE CONNECTION OR SOMETHING ELSE? I FEEL THAT TOMCAT IS NOT EXECUTING JSP COMMANDS?
IS IT POSSIBLE?WHY WILL THIS HAPPEN?
I set the JAVA_HOME and CATALINA_HOME environment to the jdk and tomcat folders resp.
Is there any other thing that I need to set in classpath? Should I have my project as a
WAR file in the webapps of TOMCAT or just a folder i.e. directory structure will fine? -
Hi All,
We are on Netweaver 7.01 SP14. (well I understand we are way behind patch levels, but a simple file upload should be working ?/)
We are trying to upload (HTML &/ Image) a file in one of the KM's public folder.
As and when we select folder and click on upload we get the below message:
Below is the error trace details:

Thanks for the quick reply.
I have gone through the notes 1535201 & now on 1606563 after your advise.
Both the notes says the fix is available on 7.01 after SP 07 and we are on SP 14 already.
Also just in case I did checked with our basis and they confirmed we are a head and we have the above notes in our release already.
Unfortunately the notes are not the solution to the investigation till date.
Thanks,
Sai -

J2EE 6.20 Java Cluster - Synchronisation of EP AND J2EE Components
Hello,
<b>
J2EE 6.20 Java Cluster -> Synchronisation of EP AND J2EE Components </b>
We have a productive SAP Enterprise Portal J2EE Cluster Farm with 3 Server. The version of EP is: 6.0 SP2 Patch 28. One State Controller, one Backup Controller and one new Dialog Instance.
We would like to know, which folders, shares and other j2ee/ep-components are synchronized from the state Controller-Server to the new Dialog Instance?
Best Regards,
Ralf SteffensThank you for your response.
In the cluster administration, the Server IP column reflects the IP of the OS instance on which the server runs. The question is relative to which LDAP server each server process grabs from a round-robin type resolution.
Any other thoughts?

I had checked the INSTANCE_NAME parameter, in every profile, and is ok.
I tried a new instalation, after importing the profiles, and checking the INSTANCE_NAME, but got the same error.
Please, advice.
Thanks in advance.
Best Regards.
JorgeThanks Manoj for your advice.
We had already checked the procedures, we are working based on the System Copy Guide: "System Copy for SAP Systems Based on SAP NetWeaver 7.0 SR3 ABAP+Java".
I had to mention that source and target systems are HP-UX, 11.23, Itanium and the DataBase is Oracle 10.2.02.
The copy was made from a Central System (ABAP + Java) to a High-Availability System (ABAP + Java), and the problem appeared when copying the Central Instance.
Thanks in adavance.
Regards.

I would appreciate if someone can explanation my long list of questions regarding
the deployment of EJB in cluster environment.
I can't run the cluster EJB example( Teller/Account) in a cluster(contains two
server2). I always get
java.rmi.RemoteException: Unable to
resolve examples.cluster.ejb.Account
Home. Resolved: 'examples.cluster.ejb'
Unresolved:'AccountHome'
Following is my setup:
Machine A: exampleServer:7001 (admin server)
Machine A: testServer1:8001 (Managed server)
Machine B: testServer1_B:8001(Managed server)
MyCluster : testServer1, testServer1_B
Test Client:
java examples.cluster.ejb.Client "t3://Machine A:8001"
======================
Q1: Should I use 8001 or 7001 as cluster port number?
Q2: What will happen when we click "apply" after select/unselect the server in
the "target", "server" tab?
Q3: And what will happen if we click deploy/undeploy check box in "configuration"
tab of EJB item?
Q4: I check the JNDI tree from all above three servers can't find out JNDI tree
doesn't reflect the change I did in Q2 or Q3.
Q5: What is the right way to deploy EJB components, should we select both cluster
and server in the "target" tab?
Q6: I got this message from one of the server when I try to undeploy/deploy ejb
object.
"examples.cluster.ejb.TellerHome_EO in the jndi tree is non clusterable
and you have tried to bind more
once? How could I make it clusterable?
Q7: Undeploy and EJB doesn't work and sometime I still get " JNDI name in use"
from the server.
How could I fix it.
Thanks
First I can tell you that the ports have to be the same, be on the the
same network , i.e. Telnet into the other m/c. Next which you probably
have done is the properties files. Per-cluster ...

How do i run java application on IIS
Hi,
Can I run java application on IIS(Internet information Server)?
If yes, How do i do that?
My java application contains JSP,Servlets and EJB.
To run java application on IIS which plug in should i use.
Can anybody help me This is urgent...........
ThanxYou can try using Macromedia JRUN version 4. Any of the version will have an ISAPI filter which you can add to the IIS site of your JSP/Servlet.
The JRUN ISAPI filter will establish connection to the JRUN proxy listener on a port. This port is called proxy listener port. Basically once you install the ISAPI, it will have config file called jrun.ini
Check for the ProxyPort entry in jrun.ini (or something like this - sorry, I can't remember the exact entry). It should match to the proxy listener port where of the server where your JSP/Servlet is intalled.
Good luck !
