RTSP:Listening Port- Server Class

I have been given a assignment which I have to write a detailed description of the main method from the Server class (available from http://www.csee.umbc.edu/~pmundur/courses/CMSC691C/lab5-kurose-ross.html)
An example of the level of description that is required is
The parse_server_response method of the Client class: The method starts by initialising a local variable
to zero. In lines 342 to 362, the Client tries to read the three lines of the server response. If this is
unsuccessful for any reason, the catch clause (lines 366 – 369) is executed.
I am new to JAVA, so wondered what is the best way to go about it e.g. suggested tutorial on RTSP:Listening port etc and any websites which will help me in getting an understanding of this kind of coding.
It is quite frustrating as we were only taught the basic of OO principles and the assignment is asking us to explain the code.
Thanks

Yes, but this does not go into the details of what is doing what. I need to know what each command line is doing??
Thnx

Oracle listener port - server health monitoring

I want to use Intermapper to monitor the health of my Oracle server. Which port should I have Intermapper watching? How do you monitor the health of your server?
Thanks.

Does Interapper have some guidance? If you're using the default listener port of 1521, you may be able to verify that the listener is up, but that doesn't mean that the database is up or accepting connections. Without actually logging in, I'm not sure what sort of monitoring you'd actually get...

WLST - Changing server's listen port

Hi,
i'm trying to change the listen port of a managed server using WLST with the following code :
readDomain('...')
cd('Servers')
cd('myServer')
set('ListenPort',8000)
updateDomain()
closeDomain()
Everything is ok so far.
Now, if i try to deploy an ear onto this server i get the folowing exception :

Re: Server machine and listening port

Is there a way to retrieve the machine a server is running on (and its listening
port) inside a Servlet or JSP?
Currently whenever I change the machine or listening port for a server (via the
console or the config.xml), I also need to find all Servlets and JSPs and alter
them accordingly to reflect the change. This becomes very tedious and cumbersome.
Thanks!

Hi Jamieson,
You can get to parameters like the server name and listen port using methods
of weblogic.management.configuration.ServerMBean
(http://edocs.bea.com/wls/docs60/javadocs/index.html). For example, to get
the listen port, use something like this:
// Create an instance of ServerMBean
weblogic.management.configuration.ServerMBean servermbean =
weblogic.management.Admin.getServer();
// Get the listen port
int port = servermbean.getListenPort();
System.out.println("port = " + port);
// Get the server listenaddress
String listenAddress = servermbean.getListenAddress();
System.out.println("listenAddress = " + listenAddress);
// To get the SSL listenport, create an instance of SSLMBean from the
ServerMBean instance
weblogic.management.configuration.SSLMBean sslmbean = servermbean.getSSL();
// Now, get the SSL listenport
int sslport = sslmbean.getListenPort();
System.out.println("sslport = " + sslport);
Robert's suggestion of using relative URLs is even better, however!

Should The Cluster server have a diff. listening port.

          Hello,
          I have 2 managed servers and the main admin server, which routes the requests
          to one of the 2 Managed Server instances on the round-robin algo... Should the
          Admin server's have a diff. listening port like(7001 as per default) to that of
          the 2 Managed servers which r listening on 7005, why is this needed, is there
          a major advantage on doing this... Plz clarify... and can we call the Managed
          servers as Cluster instances...
          Thanx in Advance


You can run admin & managed servers on the same port number.
          and yes you can call managed servers which are part of cluster called as
          clustered instances/nodes etc...

Listen port of cluster server instances

          Hi,
          Is it required for the server instances in a cluster to have the
          same listen port. In such a case it will not possible to have
          more than a single server in one machine becoz only one server can be listening
          to a single port.
          Plz guid me..
          thanx in adv

Listener port application server

Hi,
i changed the listener port in oracle.
where can i change the port in application 10.1.2?

If you are trying to edit the http server port, you need to edit OH/Apache/Apache/conf/httpd.conf configuration file and change the 'Listen' directive to a desired port value. Restart http server for the change to take effect

Identify Server listener port

Listening port in oracle app. server 10gR2 in window 2003

Hi Experts,
How to find a listening port number of app. server?
Thanks,
Jim

Check on the midtier home, the %ORACLE_HOME%\Apcahe\Apache\conf\httpd.conf file for port directive. Or if you have SSL-configured on the AS, the check ssl.conf file in the same location for the same directive.
or Alternatively, log on to the EM for midtier. Go to ports and see the Webcache port for listen.
Remember that these will be the listen ports for Webcache. For port where OHS will listen can be obtained by looking for Listen directive in the above files, and on EM, the port listed for OHS Listen (or SSL Listen, in case of SSL).

Difference between HTTP Server port and HTTP Server listen port

Hi,
What's the difference between the following?
Oracle HTTP Server port = 7780
Oracle HTTP Server listen port = 7781
They are the ports used in my 9ias 9.0.3 instance.
Please advise.
Thank you.

Hi,
The server port, 7780, is port where HTTP server response and listen ports are other ports tha HTTP Server can listen. In IAS, the default configuration, the server port is response for Web Cache and Web Cache connect with HTTP Server in listen port.

Problem when I tried to change weblogic listen port from 7001 to 80

HI! I have problem when I tried to change weblogic listen port from 7001 to 80. When I changed from 7001 to 7777 then all works ok! But why not on 80? With apache all works ok on 80 too.
I restart my weblogic server and then I have following errors.

Debuger,
It does not matter which WLS version I am using (although I'm using 10.3, the one that comes with JDev 11g).
The problem is that SOME OTHER PROCESS on your machine is listening on port 80. Guess you need to go to the Microsoft forums to find out how you can tell what that OTHER, NOT WLS process is.

Select Listener Port Number from which_table?

I'm writing a SQL script that, among other things, disconnects from Oracle and then reconnects to the same instance as a different user. I'm able to query v$database and v$instance to get most of the information I need (host, service name, etc) for the reconnect part. The only part I'm missing is the listener port number. I could hard code it to 1521, but that isn't very flexible. Currently, I'm prompting the user (which is normally me) for the listener port number in the SQL script, but that just seems a little bit lame. So my question is this: is there a view or table somewhere in the sys schema that I could use to view the listener configuration? I'm mostly working with 10gR2+ databases.

cleavitt wrote:
That is possible, but it needs to be a standard Oracle configuration if the script is to remain generic and portable. The script is actually working fine as-is. I was just trying to go the extra mile and determine the port number automatically. I could also prompt for a TNSNames entry as suggested by others, but I don't always have an entry defined for all of the Oracle instances in my company on every workstation that I work from.
Here is the script for anyone that is interested. It started out as a script that I found online, but the original did not work with 11g case-sensitive passwords and it only worked for local connections on the server.
Description:
Allows a DBA user to impersonate another user (without knowing the user's password).
Similar in function to using the SU command in Unix/Linux.
Note:
This script temporarily changes the impersonated user's password and may cause other
connection attempts by that user to fail during the moment that the temporary password is in effect.

SHOW USER
UNDEFINE username
UNDEFINE password_hash
UNDEFINE hostname
UNDEFINE servicename
UNDEFINE listenerport
WHENEVER SQLERROR CONTINUE
SET VERIFY ONAnd by so doing you just kicked the user's password expiration on down the road, negating the benefit of havng a password expiration.
Also, you locked out the legitimate user of this account, until such time as you reset it back to the original. And in the mean time, if this happens to be an account used by some automated process, that process doesn't know the new "temporary" password and runs a risk of locking the account from too many invalid connection attempts. Try to become SYSMAN or DBSNMP from this, and you will very quickly kill OEM.
This has "bad idea" written all over it. What problem is it supposed to be be solving?

RDP listening port needs to be changed on one client PC - can't connect via Anywhere Access

We have a setup with Server 2012 Essentials and 10 workstations. We have setup Anywhere Access and is working fine. We have one system (Windows 7 Pro) on the network running AADS Server (use to be called XP Unlimited). This allows several users to logon
to that PC remotely at once as well as someone local using it. This PC needs to be changed from the default 3389 port due to the new AADS Server version requiring it. When ever we change the listening port we cannot remote desktop into this PC. It is available
in Remote Web Access Portal but just sits trying to connect. We have allowed the new connection in the Windows Firewall and even turned the firewall off as a test with no luck.
My question is, can we change the default 3389 port connection that the Server redirects you to for one PC on the network? If not how do you change in the Server to look at another local port for RDP once in the portal?
Thanks, Jason

Hi Jboy,
Can you navigate to HKEY_LOCAL_MACHINE, SYSTEM, CurrentControlSet, Control, Terminal Server, WinStations and RDP-Tcp. Right click on the PortNumber dword and select Modify. Change the base to Decimal and enter a new port between 1025 and 65535
that is not already in use. Finally click OK.

MDB and Database - Listener port stops working

Hi,
I have created an MDB which does the following when a message is received from the queue.
1. Store message in database
2. do some processing
At step 1, if there is any issue with the database connection (e.g. database is not available etc), I rollback transaction. My idea is to leave the message on queue for now and retry it again after some time unless the database is back again. "Maximum retries" of the listener port is set to N but since there is no retry interval available, all N retries are done in a flash and my listener port stops working. I cannot use backout mechanism as I have to wait for the database to be back again. What are my options?

a simple JDBC rollback won't do it.
which app server are you using?
