Tuxedo Application port range

Hi All,
Is there any way to restrict tuxedo application to use a specified range of ports while it is up & running (except JSL, WSL, GWTDOMAIN) ?
Issue - The tux application comes up with random ports getting assigned to the application servers connecting to the DB, which at times occupy either of WSL, JSL, NWADDR of other tuxedo application that's scheduled to come up later on the same box.
I am looking for a way to restrict the first tux application coming up within specified port range for the servers.So they don't overlap with other tuxes (WSL,JSL,NWADDR).
Thanks in advance.

Hi,
OK, now I'm really really confused. DB ports as specified in tnsnames.ora or somehow through the OPENINFO string are destination ports, i.e., ports that some Tuxedo process will be connecting to. Server ports, i.e., ports that a local process opens for listening are only done by Tuxedo system servers such as the JSL, WSL, GWTDOMAIN, GWWS, etc. Although you can have multiple Tuxedo SHM (or MP) domains on the same physical host, they cannot share TCP/IP ports. That's a fundamental limitation of the socket implementation on most (all?) operating systems.
Normal application servers, i.e., server built with the buildserver command don't ever open up listening ports. All communication to application servers is done via System V IPC queues. The only servers that listen on network ports are Tuxedo system servers, and all of them have configurable network addresses, including host and port. So the JSL, WSL, GWTDOMAIN, etc., all can be configured to listen on specific host/port addresses.
Regarding net.ipv4.ip_local_port_range, this is an OS parameter and not a Tuxedo parameter. Tuxedo servers just listen on the ports configured in whatever configuration file is appropriate, i.e., WSL and JSL in UBBCONFIG, GWTDOAMIN in the DMCONFIG file, GWWS in the imported WSDF files. For outgoing connections such as to the database, the source port for those connections is under the control of the operating system. They should never conflict as the OS allocates free ports for each connection.
Perhaps you can tell me what it is you are seeing that you would like to see behave differently so I can get a better feeling for what the problem is. There should never be a port conflict assuming your Tuxedo network address are configured uniquely across whatever domains are on a specific host.

NAM 5.1 How to create Application with port range from cli?

Hello,
I can create new Applicaion with port range from GUI, but I can not do it from CLI
If I do it by CLI as a:
nam# application
nam# name mkst-cur-A
nam# match udp 16001-16009
nam# exit
then
nam# show application app-tag 268435576
custom:120 (268435576) mkst-cur-A
udp 16001
nam#
But if I do it by GUI and than
nam# show application app-tag 268435576
custom:120 (268435576) mkst-cur-A
udp 16001 - 16009

How to do it by CLI?

Hi Alexey,
Sure, the function you're looking for is in the ANALYSIS panel under the "CUrve Fitting" palette-- it's called "Linear Mapping". You will need to create the desired X channel prior to calling this function, though, so you will probably need to use the ANALYIS function "Generate Numeric Channel" in the "Channel Functions" palette.

What port-range in the firewall of a Socks (e.g. JSocks) server?

Hi there,
I am using the JSocks implementation of a socks v5 server.
Some of my questsions are quite general (not only specific to JSocks) and I hope that someone knows the answer. Unfortunately the forum of JSocks (sourceforge) is only rudymentary so I think this place is better to answer my questions.
However...
As I understand the socks proxy, the server waits on a specific port - normally 1080 and processes the client requests (bind, connect, accept...).
For example one client requests a bind. Then the socks server opens a port locally on the socks host and (if successful) replies the new listening port and ip to the requesting client. ...
(Forget authentication, cascaded proxies and ip-ranges at this point!)
Now, if other clients should be able to access this port, the firewall (if any) needs to allow connection to this port.
My questions:
What should be an adequate port range for the socks proxy? With other words: what is the port range of the new ports that are created for the requesting clients?
How schould a seperate firewall be configured not to conflict with a socks proxy?
Specific to JSocks (if somebody knows this he wins a virtual cookie): What is the port range that JSocks uses if it opens (generates) new ports for its clients?
Where is the port range defined in the jsocks - I havent found any?
Imagine that on the same machine there are other running applications that are listening on predefined ports. (e.g. 8080, 21, ...) - what is the best way to exclude the ports in jsocks?
Any hints and explanations are welcome!
Edited by: krafzig on Oct 28, 2008 8:27 AM

You only need one port.OK, initially I need only - lets say port 1080.
But then for example a client c1 requests a bind. The socks server opens a new socket for the client (e.g. on 50000) and tells the client on which port on the socks he is now listening, right?
In order to allow client c2 to connect to this new port the firewall needs to allow access to the new port (50000) first.
So there are more ports - there might be hundrets or thousands, right?
If its on a seperate box it doesn't matter. If its on the same box it should manage different ports.yes, different ports!
However, it should allow access to the ports that the socks opens for the clients, right?
Optimal would be a dynamic adaptation of the firewall, whenever the socks opens a new port the firewall grants access.
I assume its configurable, so its up to you.No, unfortunately it is not configurable. At least I havent found anything.
Probably won't either.???
Don't use ports already used. `netstat -a` will list all the used port on that box. obviously, and Jsocks allows to configure reusage of ports by flag true/false;
Has anybody setup a socks proxy with a firewall and knows how this is/should be done normally?
Has anybody experiences with JSocks?

Net 8 Port Range

I have Oracle 9i installed on a Solaris machine. There is an
Application server in the DMZ which is required to connect to
the Oracle 9i machine via the CheckPoint firewall machine.
Therefore, I need to add a rule in the firewall to let it go.
The default listening port for Net 8 is 1521. I found that the
port number used by Net 8 after authenticated is varied. Please
advise the port range used by Net 8, thanks.
SK

I do have the same problem and I guess the solution (using the firewall, not a VPN) is to set a range o high ports into the firewall and try to limit the response from Oracle to this range.
How can we set a range o high ports response into Oracle? I am using 8i.

Tuxedo NADDR Port assignment

Hi,
Can any body please let me know how to assign a port.I've freshly installed Tuxedo11g in a linux server.Now how can I assign port to that server.
Some body said IPC Key can be used as a port.Please provide the comments if anybody knows.

Hi,
The IPC key has nothing to do with network resources. It is purely something to identify a set of related System V IPC resources, and in the case of Tuxedo applications must be unique for each application running on a machine.
Tuxedo uses many network addresses so it's a little hard to say what exactly you are looking for. Upon completion of installation, the only network address that might be of interest is for the Tuxedo tlisten process. This is the process that helps start an application from a remote node. If your application is a single machine configuration, then the tlisten process is optional as everything can be done on the local machine. There are also network addresses associated with client listeners and gateways, although those are configured as part of the application configuration, not part of the Tuxedo installation. In other words, upon installing Tuxedo, other than the tlisten process, there are no network ports in use until an application has been configured and booted.
If you need more help, please provide a bit more explanation about what you are trying to do and where you are blocked.

"assert" a port range

i am trying to use "assert" more often.
a simple application would be with port ranges:
(1) in unix the max. priviledged port sets the lower
bound of user specifiable ports. but i don't think
this is platform independent?
(2) what is the maximum allowable port number?
i found this: 32767
thanks.

some advice: don't use assert. and, when i say this, i don't mean "don't verify your code", i mean, don't use the assert keyword. the problem comes from the fact that many checks that are asserts should really just be if blocks which throw runtimeexceptions (code that should always be enabled). and, if you have that kind of code using asserts, then you're never going to want to turn them off in production, and then, what's the point in the first place? if you are going to use asserts, i'd recommend only using them in code which is performance intensive (which you know you want turned off in production), and just use normal checks for everything else.
as for your actual question, i think 1024 tends to be a "standard" for the max privileged port number.

Port range triggering limitation - WRT600N - Most current firmware applied

Are there plans to enhance or correct the current limitation of the port range triggering?
Example
Triggering port range                            Forwarding port range
28955 - 28955                                         1024-65534
6131-6131                                                1494-1494
Although my triggering ports do not overlap; I am unable to save the above settings since the forwarded port range of 1494-1494 falls within the 1024-65534 range.
Basically, I can only use this feature with applications that do not overlap their forwarded ports. But, since there are many apps that use random ports within the 1024-65534 range this is extremely limiting.
Any help would be appreciated.
W

You can forward each port exactly once. The first entry in the list will always be the one executed. There is no other way to do this because otherwise the router would have to duplicate packets which it does not. Port forwarding is just a part of the NAT process. The error message prevents you from setting up those two forwardings which would be meaningless because the second 1494 forwarding would never occur.
The best approach is either splitting the range into multiple ranges and exclude 1494 completely or using the DMZ host feature. The DMZ host receives all ports which are not forwarded otherwise. This of course includes the privileged ports which you don't forward at this time but it may be a simple option replacing the first forwarding rule.

Port/Port Range Forward limit on Airport Extreme (N)

Hi there,
Can anyone please tell me if there is a limit to how many ports I can forward to separate machines in my LAN in the new Airport Exreme N?
Currently routers like the Linksys WRT300N only provide 10 items for port forwarding and port range forwarding, respectively. Flashing a Linksys router with DD-WRT gives you an unlimited amount.
Thanks very much!
Mac OS X (10.4.8)

There is no noticeable limit. Everything I see in the manual hints that you should be able to shove as many as will fit into memory... which is a lot.
The main reason for the limitation is that companies like Linksys, for whatever reason, do not like to mess with the complicated HTML required to support 'unlimited' port forwarding in their tool. They get around the complexity by putting enough fields on the page so that they hope their customers don't run out.
In Apple's case, the configuration tool is a native application, rather than a web page, so it is simple to support 'unlimited' port forwarding.

ORMI port ranges problem

From the following Guide:
http://download-west.oracle.com/docs/cd/B14099_19/core.1012/b13995/ports.htm#ASADM301
"When changing an OC4J port number, you typically specify a new port range. The range may be a simple port range (12501-12600), a comma separated list of ports (12501, 12504, 12507), or a combination of both (12501-12580, 12583, 12590-12600). By default, the ranges contain 100 ports. If you specify a range that is too narrow, you may encounter problems when starting OC4J instances. The AJP and RMI port ranges are required; the others are optional."
The problem I'm having is that an external client application needs to know the ORMI port of an OC4J instance running on OAS; but the port can by dynamic. I was thinking of just removing the port range (ex: set it to 3203-3203), but the above warning concerns me...
Any thoughts?

Good question.
What we do in this case is to use a JNDI URL that uses the fixed OPMN service to locate the port for the target OC4J instance. This insulates you from any movement in the ORMI port on the OC4J instance when its started.
See the EJB doc here --
http://download-west.oracle.com/docs/cd/B14099_19/web.1012/b15505/access.htm#i1019709
Location
All ports, including the RMI port, are dynamically set by OPMN when each OC4J instance starts. When you specify the following URL in the client JNDI properties, the client-side OC4J retrieves the dynamic ports for the instance, and chooses one from the list for communication.
java.naming.provider.url= opmn:ormi://<opmn_host>:<opmn_port>:<oc4j_instance>/<application-name>
The OPMN host name and port number is retrieved from the opmn.xml file. In most cases, OPMN is located on the same machine as the OC4J instance. However, you must specify the host name in case it is located on another machine. The OPMN port number is optional; if excluded, the default is port 6003. The OPMN port is specified in opmn.xml.
The reason we have a port range is
1. To support multiple installations on the same server, so that ports don't conflict.
2. To support the situation where you run multiple processes for the OC4J instance definition (so they all need different ports running on the same machine)
If you don't run into any of these, then setting a single port in opmn.xml for ORMI is fine and you can then configure the client to use the fixed, known port.

Establishment of XA "Thread of Control" in a Tuxedo application

Hello there,
I am assigned the task of developing an XA compliant resource manager so that a client can use the C interface to our JMS messaging system from a Tuxedo application and have the application's transactions managed by it. The query I have here is abbout establishing the "thread of control" in a Tuxedo context. I'll set out my understanding and the particular queries that I have in the hope that you can confirm whether my understanding is correct and maybe point me in the right direction.
The XA Specification clearly sets out the requirements for
successful distributed transaction processing, and the important roles within this for the three participants: the application programme (AP), the resource manager (RM) and the transaction manager (TM). The key concept in XA is the Thread of Control as described in section 2.2.8 of
the specification. Here is the paragraph describing the pivotal role that identification of thread of control has in transaction coordination:
<quot>The thread concept is central to the TM's coordination on RMs. APs call RMs to request work
while TMs call RMs to delineate transaction branches. The way the RM knows that a given work request pertains to a given branch is that the AP and the TM both call it from the same thread of control. For example, an AP thread calls the TM to declare the start of a global
transaction. The TM records this fact and informs RMs. After the AP regains control it uses the native interface of one or more RMs to do work. The RM receives the calls from the AP and TM in the same thread of control.
Certain XA routines, therefore, must be called from a particular thread.</quot>
In developing a RM the key question is what should be used to identify thread of control so that work can be properly assigned to the correct transaction or more specifically XID. The obvious choice here is the thread identifier itself (such as would be returned by
PRThread* PR_GetCurrentThread(void) when using the Netscape Portable Runtime library).
As long as AP, RM and TM are all in one process this is not a difficult problem, however many threads may
be created. It will also work for in our messaging system in the case where branches of the same transaction are executed in separate processes of this type. This is because "transaction assembly" occurs on the "server" when JMS messages are received there. A Message is assigned to a transaction on an individual basis. This also gives us the flexibility to implement various connection pooling mechanisms or use a single connection to transfer messages
for many different transactions along with messages not participating in an XA transaction at all.
However, Tuxedo presents a challenge as there cannot be a single thread in this sense as the participants are distributed across several processes. These processes are respectively, client; server and RM; TMS. There are at least two TMS to avoid blocking problems and potentially very many server-RMs. Given this situation how then is it possible for the RM to match up units of work requested by various services with the XIDs that it has been informed of by the TMS? One assumes that a different thread will run in the server/RM process for:
a) TMS to indicate to RM that a transaction has started, ended, etc., one distinct thread for each of these calls.
b) service execution, one distinct thread for each call, where there may be many of these making up
the work of one transaction
It is obviously preferable from our point of view that our RM should not have to use Tuxedo specific code, but if this is unavoidable then we shall have to live with it.
BTW in case it is relevant I'm assuming that the RM will not use dynamic registration.
Thanks for any help,
Gillian Horne

Gillian,
When Tuxedo issues an xa_start() call, the matching xa_end() call will
always be executed in the same thread of the same process.
If another xa_start() is executed at a later point for the same transaction,
that call could be made in a different process, in a different thread of the
same process, or in the same thread of the same process.
Tuxedo will call xa_end() with the TMSUSPEND|TMMIGRATE flag pair only for
certain CORBA transactions. If your application does not use CORBA, then it
would be acceptable to develop an RM with the TMNOMIGRATE flag set in the RM
switch. Tuxedo does not use asynchronous XA operations, so you do not ened
to develop an RM with the TMUSEASYNC flag set.
The xa_prepare() call for a particular transaction branch can be made in
different process or thread from the xa_commit() or xa_rollback() call that
follows it.
Except in the case of transactions started with the Tuxedo AUTOTRAN feature,
the xa_prepare() and xa_commit() calls for a particular transaction branch
will almost always be made in different processes from the processes that
performed xa_start()/xa_end() calls for that transaction branch.
There shouldn't be any need to write special RM code for Tuxedo. Popular
RMs such as Oracle, Informix, DB2, MQ Series, and others have all been able
to work with Tuxedo, with the former Top End product, with Encina, and with
other transaction monitors.
I hope this information is of help in implementing your RM.

Unable to Save in Port Range Forwarding

I'm using the BEFW11S4 wireless router and am unable to save the new port range forwarding settings I have entered. Everytime I click Save Settings, I receive a box which reads:
"The server 192.168.1.1 at Linksys BEFW11S4 V4 requires a username and password.
Warning: This server is requesting that your username and password be sent in an insecure manner (basic authentication without a secure connection)."
When I enter the same u/p that I used to access the router in the first place, it rejects and keeps bringing up the log in screen.
I cannot get the port range forwarding to save at all due to this.
Does anyone have any suggestions?
Thank you!

try remembering the password you used for first time while installing the router .... if not then use default password admin with out any username ....
If still not working then you need to reset the router ....

Data Transfer Port ranges in FTPS with SSL in File Adapter

Hi,
I would appreciate if you could give me pointers reagrding the below issue.
We are on XI 3.0.
For one interface, I have to configure the FTP File adapter to pick up the files from external server.
The connection is secure and should be FTPS with SSL.
I have the certificate from the 3rd party and have it installed on our XI development server.
The change has been made in our firewall to allow the connection to the host IP and port 21 which is configured at the target party as Explicit FTPS port and they have allowed access to our Server IP in their firewall.
I have configured other FTPS connections and they worked fine but this is the only one that has been giving me so much trouble.
The error i get today is:
Error occurred while connecting to the FTP server "60.234.48.106:21": java.net.SocketException: Connection reset
Yesterday, i got the below error:
Error occurred while connecting to the FTP server "60.234.48.106:21": iaik.security.ssl.SSLException: Server certificate rejected by ChainVerifier
The Vendor has suggested to get the firewall ports 21 and 28000:30000 (data transfer) to be opened.
He has also provided with the certificate passphrase additionally to the user name and password needed to make the connection.
When i tried the connection from the XI development to the vendor server, via the Telnet, it looked like it worked.
Please advice.
Regards,
Archana

1. Open the port ranges. FTPS usually requires you to open ports in the range of 65024 through 65535 for Passive FTP data
connections
2. Use the CA name in the certificate. it should be same as of the host name of the FTPS server

OC4J_BPEL no port available from the port range

To All,
We could not start our BPEL Process Manager and OC4J_BPEL. We have shut down and restarted the Linux server repeatedly and re-running the IRCA. All stacks are running except the OC4J_BPEL and BPM.
We keep receiving the following message when we start the BPM:
BPEL Process Manager
OraBPEL : OC4J_BPEL no port available from the port range
OraBPEL : OC4J_BPEL - failed to start a managed process after the maximum retry limit
OC4J_BPEL
OraBPEL : OC4J_BPEL no port available from the port range
OraBPEL : OC4J_BPEL - failed to start a managed process after the maximum retry limit
Our OraBPEL is on a single HP NetServer LH6000 with Red Head AS 3.0, Oracle 10g DB and AS middle tier all in the same machine. The server was running a batch BPEL process. After running 2 hrs and process 12,000 records it was brought down by a single runtime exception. We were able to bring back the Oracle 10g AS middle tier but not the OC4J_BPEL instance. Any help would be appreciated.

I changed the OC4J_BPEL port from 3201 to 3211 fix the problem. It was conflicted with the home instance that is using port 3201. However that still can not get rid of the OC4J-BPEL failed to start a managed process after the maximum retry limit.

OBI11g intallation issue - Error in validating the port range for auto port
