Communication port for JCo

Hi All,
I am about to install JCo in Solaris server. I want to confirm one thing.
Which is the port I need to open up for JCo to communicate to SAP server?
The version of JCo is "SAP JCo 2.1.8 ".
Is there any documents regarding the communication port?
All inputs are welcome
Regards
George

I think you need to open 3200 and 3300.
The following is the list of all related ports:
sapdp## 32##/tcp # SAP Dispatcher.       3200 + System-Number
sapgw## 33##/tcp # SAP Gateway.          3300 + System-Number
sapsp## 34##/tcp #                       3400 + System-Number
sapms## 36##/tcp # SAP Message Server.   3600 + System-Number
sapdp##s 47##/tcp # SAP Secure Dispatcher 4700 + System-number
sapgw##s 48##/tcp # SAP Secure Gateway    4800 + System-Number
sapgw97 3397/tcp # SAP Oss
sapgw98 3398/tcp # SAPcomm
sapgw99 3399/tcp # SAP EPS
sapdp99 3299/tcp # SAProuter

Client communication port for workgroup servers

We have SCCM 2012 R2 Single Primary Site in intranet. We have PKI with ADCS 2012. We are in process of mirating to HTTPS communication using certificates. We have few servers in workgroup and we plan to manage those servers with configuration manager by
manually installing client and specifying smsmp=sccm fqdn. for lookup management point.
Can we change client communication port for these servers?
For successful client communication do we need to open any ports except 443 in firewall?
What all ports needed to be open in this scenario?

Hi,
You configure the Communications port for the MP in the site so they must use the same ports, you can configure alternate ports so if it cannot communicate on port 443 it tries the next port.
http://technet.microsoft.com/en-us/library/gg712276.aspx
443 is sufficient, the client will also try to communicate on port 10123 for Client Notification,
http://www.google.se/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0CCsQFjAA&url=http%3A%2F%2Fblogs.technet.com%2Fb%2Fconfigmgrteam%2Farchive%2F2012%2F09%2F27%2Ffast-channel-for-system-management.aspx&ei=1dAhU7qqOIL8ygPb1IHQAQ&usg=AFQjCNF4_G2sZBMbDDtJa95LBx7EYYBrRw
But it should fallback to 443 if not available as well.

Change default communication port for BITS

We are currently using ConfigMgr2007 (native mode). We currently have a global GPO wihich is throttling BITS to 56kpbs during current business hours (8am-5pm). It has been suggest to use QoS to controll the amount of traffic used by SCCM distributions
to clients. Seeing the BITS uses HTTP (80) and HTTPS (443) by default, is there a way to change the default ports used by BITS.
I did find the following article (About Configuration Manager Client Installation Properties)
that there are two setting which can change the default ports.
CCMHTTPPORT=
CCMHTTPSPORT=
Is there any other methods to change the Default port for BITS communication as a whole.

Thanks Kent and Jason. I know I posted in the ConfigMgr forum and you pointed my to the proper documentation. We have non-Microsoft email archiving product which utilizes BITS which is the reason for the general question regarding BITS.
I did not see a dedicated forum for BITS so I posted here.
The documentation as suggested by Kent will assist with making changes for ConfigMgr if necessary.

Port for JCO connection

Hi,
I am accessing an R3 table using JCO connection. Can someone please let me know the port no. of the server which will be neccessary for doing this?
Thanks

Hi Jacob,
try {
con = cgservice.getConnection("ISOILESconnect", cp);
ix = con.createInteractionEx();
ixspec = ix.getInteractionSpec();
ixspec.setPropertyValue("Name", "Z_MESSAGES");
rf = ix.getRecordFactory();
// CCI api only has one datatype: Record
RecordFactory recordFactory = ix.getRecordFactory();
MappedRecord importParams=recordFactory.createMappedRecord("CONTAINER_OF_IMPORT_PARAMS");
MappedRecord exportParams = (MappedRecord) ix.execute(ixspec, importParams);
output = (IRecordSet) exportParams.get("LI_MESSAGES");
This is the piece of code im using, I have already created a system on both the servers and tested them successfuly. But for some reason it works on one but does not give an output when i run it on the other server.
I get an error which tells me that no output is returned.
Thanks.

Random jmx communication port

i have a setup with 2 node agents and 1 DAS behind a firewall.
from what i understand, in order for the node agents to communicate with the DAS, a communication channel is created on a random port via JMX.
the problem here is with the random port having to operate over a firewall. Is there any way to assign a fixed port for JMX communication?

8686 is the initial communication port for JMX,
do an "grep jmx-connector" on server.xml, you can see 3 ports as a result. Open those ports in your firewall and try.
One will be 8686 which will be for DAS-SERVER
<admin-service system-jmx-connector-name="system" type="das-and-server">another with variable JMX_SYSTEM_CONNECTOR_PORT, which you can see from admin console. This is for Server
<admin-service system-jmx-connector-name="system" type="server">another some random port number after nodeagent definition for JMX
<node-agent name="node agent name" start-servers-in-startup="true" system-jmx-connector-name="system">Regards

Can there be more than one port for the same logical system

Can we have more than one TRFC port for tranferring data from one logical system to another?
The requirement is to transfer same basic idoc type from one logical system to another through two different ports. Is it possible?
For eg. some specific data (country specific) for the same basic idoc type can be sent through a separate port and the other data through a different port inorder to distinguish between the two.

Hi Shital,
I don't think so. Because of that what i told you. There would be a dirty trick (back routing) to solve your issue. But its quite difficult and not standard. You create two http receiver services and two http sender services. You route your message depending on payload to the one or the other http receiver channel. The receiver is in both cases: THE XI! Now you have a second message, which you can route to IDoc adapter. But in this case you have different sender and in the receiver determination you can put the sender, so you will be able to use different communication channnels and so different ports / destinations.
Advantage: Your task would run, no performance problem (http: very good, asynchron)
Handicap: You see every message double in the monitoring, the scenario is not easy to understand and it is a big task 4 other people to change it.

How do I create Labview VISA ports for *individual* GPIB instruments using Prologix USB GPIB controller?

Hello,
I'm trying to use a Prologix USB GPIB controller to control GPIB
instruments, and I would like to have a virtual serial (VISA) port for
*each instrument*, as is the case with a normal GPIB controller with a
standard NI driver. However this is not what the Prologix driver
provides -- it provides a single VISA virtual serial port for the
entire controller. To address the instrument with GPIB address 11,
you first send "++addr 11" to the serial port, and then you're talking
to instrument 11. However, this means I have to change all old
Labview programs.
Is it possible to create a "wrapper" function of some kind that will
define a virtual serial (VISA) port for each *instrument* on the
controller? For example, to talk to GPIB instrument 11, call it
ASRL3::11::INSTR, each time it is written to it would have to write to
the virtual serial port of the controller, say ASRL3::INSTR, first "+
+addr 11" and then the command that is sent to it.
A clearer explanation of the difference (i.e. incompatibility), and of
my objective:
1) A normal GPIB controller with NI driver: I go to the NI
Measurement & Instrumentation Panel, under GPIB, and Scan for
Instruments; all the live instruments show up; subsequently when I
want to use Labview programs that use VISA ports, the VISA drop boxes
allow me to choose a different port for each instrument, e.g.
"GPIB0::11::INSTR", "GPIB0::12::INSTR" would be instruments at
addresses GPIB 11 and GPIB 12.
2) The Prologix GPIB controller that plugs into a USB port: In
Labview you get a *single* VISA virtual serial port, ASRL3::INSTR, for
the entire GPIB0 controller. Therefore to address GPIB instrument 11,
you write "++addr 11" to the virtual serial port ASRL3::INSTR, and
then you are communicating with device 11, so you can write and read
ASRL3::INSTR to talk to that device. Then to talk to device GPIB 12,
you write "++addr 12" to the same VISA port, and then you are talking
to that device. The problem is that this requires recoding all
Labview code, whereas I would like to be able to use the same program
either with a normal or with a Prologix GPIB controller. Therefore, I
would like to create code that scans the controller for all GPIB
attached devices and creates VISA ports for all. Such ports, when
written to, would have to first write "++addr DEVICENUM" to
ASRL3::INSTR (i.e. the port of the GPIB-USB controller) where
DEVICENUM is the GPIB address of the instrument corresponding to that
port, and then would have to do a write or read or whatever function
is being done on that instrument VISA port.
I haven't figured out if it is possible to do this easily. Help and
pointers on where to look for hints would be much appreciated. Many
thanks!
Milos

My first impression is that if you don't want to make any changes at all to existing programs is that the wrapper you need is one around VISA. You would need to intercept all of the calls into the NI VISA driver. If you create your own visa32.dll and in there, change the addressing and then call the real VISA driver, you might (repeat, might) get something to work. If this would even work, you still might find that you have to make significant changes anyway. The serial connection is going to be considerably slower, and interface specific functions such as service request handling, bus triggering of multiple instruments, etc., would be difficult to impossible. This would be a lot of work, imho, to just save a couple of hundred dollars over a real GPIB controller. I've seen this Prologix device before and have even used NI's RS-232->GPIB controller. The Prologix intended use to me seems to me more for a hobbyist or very casual user. Of course, I'm used to having multiple GPIB instruments worth 10s/100s of thousands of dollars and the cost of an fully compliant GPIB controller is just lost in the noise.

Error while creating logical port for Reporting

Hi,
In one of the training materials for Duet Enterprise, i saw the steps for creating logical port for the consumer proxy /IWTNG/CO_PXY_RECORDS_REPOSITO.
When i am trying to create the logical port, i am getting an error saying,
" SRT Framework exception: Error in WSDL access: Exception occurred in communication framework:Error in HTTP Framework:500 Native SSL error
https://<server:port>/_vti_bin/OBAFileReceiver.asmx?wsdl "
I would like to know is it really necessary to create this logical port for "Reporting Scenario" and is it not created automaticallly using the Installation Wizard??
And in case it has to be created, how to resolve this SRT framework exception?
~ Ramanath.

Hi,
the consumer proxy /IWTNG/CO_PXY_RECORDS_REPOSITO was used in Duet Enterprise SP01. Now with SP02 the consume proxy /IWTNG/CO_OBAFILE_RECEIVER_SOA is created.
However, the SSL error that you are getting looks a little strange (it does not mean that there is an error, but it is worth checking):
So can you go to SOAMANAGER -> Service Administration -> Single Service Configuration. In here select "Consumer Proxy" from the "Search by", Search Pattern "/IWTNG/CO_OBAFILE_RECEIVER_SOA" and Field: Both.
You should find one entry. Select it and click "Apply Selection".
Now go to the Configurations tab. Here you should see one Logical Port with name "LOGICALPORTFORREPORTING" with Creation Type "Manually Created". In fact this logical port was created by the Wizard.
Click on Display and scroll down again. Now in the "Additional Information" tab there is a string after HTTP Destination, e.g. 0050568E3F5A1ED096F22339C44BAF83.
Copy this value and go to your SAP GUI -> Transaction SM59.
Here click on Find/Search and search for this HTTP Destination. You should find one Type G RFC Destination that has the target host of your SharePoint server and the path prefix /_vti_bin/OBAFileReceiver.asmx.
Now you can test the service. Just click on Connection Test. The result should be a HTTP Response: 200.
If not, then something went wrong with the automatic configuration and we should take another look at it (for example maybe the SSL certificate from SharePoint that was imported by the Wizard is not valid)

Holger.

Creating new logical ports for WSDL with several port types not working

Hi all,
I am trying to integrate some BODS webservice into the BPM. I am using CE 7.2 Kernel Version: 7.20.3710. When I am trying to assign a provider system in the application configuration I get following error:
The provider system successfully found the needed service, but its wsdl is without webservice policy. Thus the generated client configuration might not work because of different configurations between service and client (most probable a difference in the security settings). Either assign a provider system with access to wsdl with policy or manually create the client configuration.
The regarding provider system is using a communication profil where the authentication method is set to "none". Normally this configuration should work, but it isn't.
So I started to create new logical ports for each port type. But then I get the error:
Port type name of loaded WSDL does not match the port type name of the Service Reference.
I checked already the port type names in the WSDL but they are 100% the same. What I found was that the configuration is always trying to use the first port type in the WSDL. So I am not able to configure the other port types in the service group.
I also tried to do the same thing using a WSDL with just one port type and surprise it is working...
I hope somebody can help me out
Thanks in advance

Error in BPM: "COMMUNICATION FAILURE" during JCo call. Error opening an RFC

hello experts
i am receiving the above error incase of BPM scenario where i am having a Transform step and synchronous RFC step.
i referred to the few threads discussing such problems and was trying to find whether my mapping is correct and i tested my mappings using my payload which looks good.
When looked into the Mapping trace of the BPM "Show container" i found error ""COMMUNICATION FAILURE" during JCo call. Error opening an RFC connection" and it seems that when BPM is attempting to call interface mapping it is throwing this error.
Thanks in advance.

rajeev

hi,
I think no problen with the mapping part,

HOW TO CREATE SERVICE FOR SENDER SOAP COMMUNICATION CHANNEL FOR ECC PROXY

Hi Experts,
I need generate the service for sender soap communication channel for target url to receive the inbound proxy.
my scenario is like SOAP to proxy. while using receiver proxy also we are planing using AAE method .
i am using SOAP sender and SOAp receiver communication channel .i need to provide the target url for this communication channel.
how to generate the url for this and what is the transaction code .
Please help us.
Regards
Ravinder.S

Hi Ravinder,
Q.my scenario is like SOAP to proxy. while using receiver proxy also we are planing using AAE method.
SOAP to Poxy in this case.
For sender SOAP system, we can generate the WSDL link in ID part.
for Reveiver proxy give the integration engine URL.
http://IP:PORT/sap/xi/engine?type=entry
how to generate the url for this and what is the transaction code
There is no transaction code for generating the URL.
i hope this will help.
