Ports on SAP R/3

Hi All,
In my SAP R/3 system the dispatcher port is 3200 and the message server port is 3600. All my portal applications when connecting to the backend hit the port 3200 directly and load balancing is not happenning. Can we make the message server port also as 3200 to enable load balancing?
Regards,
Sridevi

Does it mean that all connections to SAP R/3 by default hits the port 3200? Can this be changed to 3600?
Then you create the JCO destination where specify the R3 server information you can select direct using appl server -->
this will conect to 3200 in your case , if you select using Logon Balancing and specify all correctly (information about logon group, and your portal must know your sapmsSID (SID your productive system sid) service in services file for this) When your application will connect to 3600 and after redirected to needed instance ...
Regards.

How to change Port for SAP Client on SAP R/3 Server?

The defualt port for SAP GUI Client is 3200.
How could I change the SAP GUI Client port to say 5222 instead of 3200?
How can I view the full list of all ports required by SAP R/3?

Freddy,
I don't have the document handy but there was a document on service.sap.com/security which would give you a list of all the ports. SAP's wording is some thing like "specific ports are fixed and SAP does not support changing that port number".
In case of GUI client and your example of 3200, as you know 00 is based on the fact that that is your instance number. You could change last two numbers by assigning a different instance number (and not 00).
Thanks

Changing Default SMTP port in SAP Portal/Web AS java 6.40

Hi all,
We are configuring notification service in SAP Portal 6.0 with SPS 15. The SMTP server not using 25 port which is default for SMTP. when the server is trying to send notification it is pointing to IP address and 25 port. HOw can I change the default port to custom defined port in Portal/Web AS Java.
Thanks in advance.
regards,
Kishore.

Hi,
may be that Im a little bit to late, but for the next one who has the same problem the solution could be interesting.
You can change the default smpt port on Web AS Java in the server parameters of the java virtual maschine.
Open the SAP J2EE Config-Tool. Goto cluster-data | instance_<instance-id> | server_<server-id>. In the tab General insert unter Java parameters the line
-Dmail.smtp.port=<port> where <port> ist the port number of your smtp server.
Testet with SAP NetWeaver Portals / SAP NW 04s and SUN Java-VM but should also work with SAP NW 04.

Ports in SAP BPC for MS Office (Excel, Word or PowerPoint).

Hello to all,
I'm trying to find what ports do I have to open to my firewall to let the customer in to the SAP BPC from the MS Office (Excel, Word or PowerPoint).
I've tried to find it, but I didn't fiond anything in the manuals.
Please I need help.
Thank you in advance.
Pablo Mortera.

You really need to go through the Master & Installation guide as Alwin pointed out. This guide will easily answer questions like this as well as the other question you have posted lately.
From the guide;
If your Application, Web, or Reporting Services server components will be
accessed through a firewall, you should verify with your network
administrator which TCP ports to choose during the installation of
OutlookSoft. By default, port 80 is the setting for standard http access,
and port 443 is the setting for https access. If you require a service to
listen on a different port, you can specify it during the installation program
in u2018Advanced Settings.u2019 See Standard and Advanced settings on page 18.
u2022 Make sure all required server ports are open, and there is communication
between the physical servers on which you are going to install the server
components.
All required ports must be opened for inbound/outbound traffic. By default,
OutlookSoft requires that Ports 80 (used by http) and 1443 (used by SQL
2000/2005), 2725 (used by OLAP 2000) and 2383 (used by OLAP 2005)
are open. For information on the required ports, see Server Manager Help.

Porting open source application to SAP WAS

Hi,
I'm porting jZForum ( http://www.jzforum.org ) to integrate it with SAP WAS and SAP Dictionary instead of internally used
HypersonicSQL database. I mainly changed obtaining connection to the database directly through JDBC:
jdbc:hsqldb:hsql://localhost:1476
into connection obtained through JNDI with Spring Framework (more precisely through org.springframework.jndi.JndiObjectFactoryBean class) :
jdbc/MY_DATABASE
with connection pooling parameters:
initial connections: 1
maximum connections: 50
maximum time to wait for connection: 120
expiration: yes
connection lifetime: 600
cleanup thread: 300
Unfortunately ported jzForum seems to "hang on". I see in Log Viewer (Visual Administrator) log that it is quering database with a lot of SELECTs,
I assume that it is indexer which on startup is indexing all objects from the forum to speed up searching this objects in the future.
After about 2-3 minutes hanging on, application shows generated page, but every subsequent request to
the server cause hanging on in the same way.
I assume that it might be the case that application is obtaining through JNDI connection to the database, but is
not releasing it. I have examined entire jzForum code, and closed all unnecesary Connection in final Java statements,
but it unfortunately didn't help.
Original jzForum (not ported to SAP Dictionary) works on SAP WAS just perfectly.
Have someone else experience with porting open source application from some database (eg. HSQL) to SAP Dictionary ?
Maybe it is a problem with Spring Framework implementation ? Maybe it is a problem with wrongly configured connection pool ?
I have no idea at the moment. Every help will be appreciated.
Kind regards,
Marcin Zduniak

Hi Marcin,
from what you are describing, the port to JNDI obtained connections and your "research" in visual admin uncovered some issues with the original code ( not closing open connection ).
My attempt to explain your difficulties:
1. Working with hsqldb in direct mode, where hsqldb connection are obtained by driver.getConnection(), works well, becuse GC "reclaims" unused but not closed
connections. Things seems to work out this way.
2. Getting connections through JNDI involves a datasource with its associated db pool. Not closed connections are then "trapped" in the pool as long as is specified by the "connection lifetime" DS parameter. Things get worse by the time, becuse the application leaks constantly connections.
Remedy for the problems described in 2:
- middle term: fix the application: here spring might be useful, consider using its JDBC support classes!
- short term: set the connection lifetime to a small value to let pool reclaim the unclosed connections
Hope it helps a bit,
Gregor

SAP router ports on firewall

Is it required to open all the ports in firewall which are mentioned in SAProuter saproutab file. and RDP port

Hello Hardeep,
These 16 Servers needs to be accessed through the SAP Router machine or from SAP Router Machine and the ports for these servers should be opened in such a way. Its not necessary to access this servers directly from other network whereas the port for SAP Router machine should be accessed directly form outside network.

How to change the default port of webdispatcher

Hello Everyone,
We wish to know to how to change the default port of SAP webpatcher port from 81$$ to 80.
Appreciate your response.
Thanks,
Vadi

Hello Vadi
you have to change the PORT value in your profile parameter from 81$$ to 80
icm/server_port_0 = PROT=HTTP,PORT=81$$ to
icm/server_port_0 = PROT=HTTP,PORT=80
Also, in SMICM, then change http service port and activate it and above parameter will require SAP restart
$$ is used generally to accomodate multiple port services running in SMICM and so as to avoid the parameter setting according to instance number of any system.
thanks

Problem in Outbound IDOC from SAP R/3

Hi,
I am working on to send an IDOC from SAP R/3 to XI.
I configured all necessary things as follows:
1. Created for XI in sender system -- RFC dest, PORT and a partner profile with an outbound parameters and reciever port as XI port.
2. created for sender system in XI -- RFC dest, PORT(as SAP<SID>) in IDX1 and assigned an idoc type(coming from sender system) to the port.
Now I am trying to push the IDOC from sender system using Test IDOC transaction and gets success message as data is passed to port.
My problem is I am not able to see any message in SM58 of XI server.
Could anyone help me out?
Thanks In Advance.
Yaseen.

Yasseen,
you hardly see the idocs in Xi in sm58. Try sxmb_moni.
If you see anything there try sm58 on the sending R/3. There you see if you have connection problems (eg authorization in XI or missing receiver determinitions).
Hope it hellps,
helge

IDOC - XI - IDOC same port name in IDX1

Hello,
i have a problem in defining multiple receiver systems in IDX1.
We have to send idocs to different system and some of them have the same SID.
Receivers would have the same port name SAP(SID) ex : SAPPRD
How could xi know which is the correct receiver port?
Thanks,
Laurent.

Port name might be the same, but the RFC destination for each port is different. We use the the combination of port and RFC destination in communication also. Hence I guess there should not be any conflict.
I may be wrong here. Correct me if am wrong.

Jai Shankar

IDOC outbound port - No service for system X, client Y in Integration Direc

Hi all,
We have a problem when sending an IDOC from ECC to XI to Legacy. At ECC, tx SMQS, we got the error "No service for system SAPEQ0, client 400, in Integration Directory".
I don't know what we need to do in ID to provide this service and solve this error...
Our ECC is configured on SLD as EQ0_400 (Logical name EQ0CLNT400), and the scenario was developed at Integration Directory using EQ0_400.
Debugging standard function that send the IDOC, I found that it ever uses the sender port as "SAP" + SY-SYSID... So I'm confusing, is necessary to configure the system in SLD whith this name "SAPEQ0"?
thanks.
roberti

Glad to hear that you got it working.
>>"Error occurred during back-routing Error in communication channel".
Can you give some more description about the error?
Hope you have configured a IDOC receiver communication channel poiting to the ECCwith no reciever agreement attached to it.

Jai Shankar

Can't open HTTP server socket on port 50000 in dispatcher

We get the following message in the console_log for the dispatcher.
ID000544: Error starting service http. Can't start the service due to java.io.IO
Exception: Can't open HTTP server socket on port 50000
[ServiceManager]: ID000544: Error starting service http. Can't start the service
due to java.io.IOException: Can't open HTTP server socket on port 50000
[Framework -> criticalShutdown] Service http startup error!
Anyone have any ideas what might be the problem?
Thanks,
Keith

Hello Keith,
this errors occurs when the port http 50000 is already taken. Please could you check if this port on your machine is free or an other dispacther instance is already started on same machine. You can change the port in sap j2ee config tool (dispatcher-> services->http)

Sender port in an Outbound IDoc

Hi
Can someone please mention where is configuration for IDoc sendor port.
We generally give Receiver port information in outbound parameters in partner profile(WE20). But there is no place where we give the Sender port information.
When an outbound idoc gets created, in the control records you can find the Sender port. Can someone tell from where this port is picked up.
In most of the cases I can find port name SAP<SYSID>. Is this something SAP standard. ?
Thanks,
J.

Hi Brad,
Can you tell me where its hard coded. which program/func module. ?
Thanks,
J.

IDoc Scenario SAP ERP - PI(Receiver IDoc Adapter) - IDoc to Third-Party system

Dear All,
I have created a scenario to send IDocs via PI system (PI 7.1) to a third party system.
There is no message mapping involved(Only ID part)
I have imported Idoc Metadata from the source ERP system.
Created an RFC destination(BC_ERP_SEA) in the PI system of type TCP/IP with registered Server Program to third party system.(Tested success)
Created a port in IDX1 BC_ERP_SEA with above TCP/IP destination.
Receiver communication channel of type IDoc is created with the following parameters:
         RFC Destination: BC_ERP_SEA
         Segment Version: 640
         Interface Version: SAP release 4.0 or Higher
         Port: BC_ERP_SEA
         SAP Release: 640
Now when I execute the scenario, I get the following error in SM58 of PI system.
Bena IDOC_INBOUND_ASYNCHRONOUS not found on host.
Request your help for this issue.
Thanks,
Jishi

Hi,
Check below steps..it may resolve your issue
1. It is mandatory to specify Ack Destination value in IDoc_AAE sender channel. The value should be an RFC destination name which is connecting to your SAP ECC system.
2. In inboundRA resource adapter, the value for the property "local" should be set to "true".

Tulasiram.
