You should not worry about this, WebSphere plugin sitting at WebServer takes care of this by sending subsequent requests from same client to same JVM.

Seems you have not set user registry, .. you have to select user registry (OS, custom or LDAP) and accordingly input a valid userid and password. The easiest one would be OS, and provide a local OS userid/password to complete security setup.

did you check whether db2java.zip is in classpath. Refer admin.config, and make sure that all db2 related libraries are in classpath.
Also check (in case you ahve changed db2 password) :
1. After changing db2admin password, did you see whether admin.config file is modified properly to connect to db repository. Check which schema you are using inside admin.config for storing config data.
2. If you have just installed WAS V4, have u done what I specified above.
3. Check whether your DB2 services are properly started, go to services and try to start all the services, also go to db2 command line processor (I suppose you are on windows), if on unix, then go to db2 prompt and connect to WAS db repository, do "list tables for all" or "list tables", check whether WAS tables have been there and also their data is accessible.

What I feel, there is no need to recreate multiple WAS instances, also there is no need to install Network Deployment Manager. Your objective can be achieved by installing base application server. In case, you want clusters of application servers to support different environments, then you certainly need to install Network Deployment, as base version does not support clustering.
Create separate application servers, or clusters for separate environements (say, dev_server, test_server etc.), create separate virtual hosts to for your environments (say, dev_vhost, test_vhost etc.). This way you can have different URLs for different environments. In case, you have to deploy same application to diffrent app servers/clusters, all you need to do is to change the context root inside ear file.

You can set max in-memory session count property to 10 in web container using admin console. Also inside your entry servlet where you are obtaining session for a successfully authenticatde user, you need to put a check (import this package in your code com.ibm.websphere.servlet.session)
IBMSession sess = (IBMSession) request.getSession();
if(sess.isOverFlow()) throw new ServletException("Maximum number of sessions reached on the server");

Look at the reload interval setting in IBM extension file (ibm-web-ext.xmi) under WEB-INF folder, if 'reloading enabled' is true here, the application server JVM would reload any new class or other file based upon the reload interval specified.

How did you install ND and Base application server. You should have first installed Base, started and tested it. Then stop the base server and start installing ND, which will detect the existence of Base on this server and will prompt you to have unique port numbers for ND installation, choose that and finish the installation. Then you should not have port conflict. Now currently you have already installed both ND and Base, you will have to modify serverindex.xml file manually on both the installation to make both of them work together. This is messy, I would suggest you to go for fresh installation of both.

You assumption is right, every JVM will have its own instance of singleton.

New to weblogic8.1, installed trial version on windows xp. During installation, it did not ask any user id and password. Now when I start example server by invoking startExampleServer.bat, it starts fine but when I try to access to admin console at port 7001, it asks user/password, which I have no idea what to input. Any idea???

I implemented this under same scenario i.e. web server is up but application server is down. Put the following directive inside httpd.conf
ErrorDocument 500 /redirect.html
Create your custom error page, name it to redirect.html and put it under docroot, by default which is <IHS_HOME>/htdocs folder.

There seems to be problem with DB2 jdbc driver, have you upgraded the jdbc level :
Update the JDBC level IBM WebSphere Application Server V4.0 requires JDBC2.0, whereas the default installation of IBM DB2 uses JDBC1.2. To update the DB2 JDBC level, complete the following
steps: 1. Stop the DB2 JDBC Applet Server Windows service as follows: D:\> net stop "DB2 JDBC Applet Server"
2. In a command window, change to the <db2_install_path>\java12 directory where you installed DB2 and the type the following command: <db2_install_path>\java12\> usejdbc2.bat

I think, you should make these modification in setupCmdLine.sh/bat file and then check whether paths are reflecting properly.

javaranch does not show 'greater than' and 'less than' so value of DISPLAY did not go as I wanted, please set your DISPLAY variable properly DISPLAY=ip_addr_of_your_machine:0.0 then export it.

Please follow these steps and let us know whether it works or not :
1. Stop WebSphere Node properly, check no java process is running by ps -aef | grep java
2. Open a new shell, set DISPLAY=<ip_addr_of_local_machine>:0.0 then export DISPLAY, check by echo $DISPLAY whether it is set properly.
3. Start the admin server by startupServer.sh, check the tracefile when it is started properly.
4. Open adminconsole, on the same machine and leave it, this helps in initializing some x11 libraries on solaris8
Now check the problem functionality.

Does anyone know how long IBM is going to support WAS40, I read from IBM's site that its up to Sept'04, does this only mean that IBM will stop coming out with patches and fixpacks after that for WAS40, what about technical support i.e. passport advantage? Whether passport advantage is also going to be stopped in Sept'04 simultaneously?
