Adding an HTTP Connection to TREX previously installed with RFC Connection

Hi All,
On an existing TREX installation (7.0) with a RFC connection configured, is it possible to add an HTTP connection, or is it necessary to re-install the TREX with both connections?
Thanks,
Liz

Hi Liz,
No, it should not be necessary. If you are using a Windows system you'll finde more info on [SAP Help|http://help.sap.com/saphelp_nw04s/helpdata/en/ef/50688acaa0ff4aa23a23e74e8c9e73/frameset.htm].
Kind regards,
Roland

Turn off your printer.
Go to System Preferences > Print & Scan > Printers window and delete the printer from the list, then add it back.
Turn on your printer.
Any difference?

Load balance for HTTP Connection to ABAP System (Type H) RFC connection

Experts,
For proxy we are using HTTP Connection to ABAP System (Connection type H) RFC connection in PI to get connected to ECC. I only see the option to use Target host in the Target system settings than Load balance option. In general ABAP Connection (Connection type 3) has Load balancing status option in Target system settings.
My requirement is I should use a logon group with the message server when PI connects to ECC. How can we achieve this? At the moment I can only use the Central Instance or any dialog server (App server) in RFC but not a logon group.
Thanks in advance.

Problem with RFC connection - tp program not registered

Hello everyone
recently there has appeared a problem with the RFC connection on our system - we received the following set of messages:

but with no success - the program didn't appear on the list of logged clients on the system in gateway monitor. Frankly speaking we do not know now what else we can do - please help!
We have ECC 6.0 (SAP_BASIS 700 SP18) on Windows Server 2003 R2 x64.
Thanks in advance for any help.

Hi Salim
thanks for your reply.
./rfcexec -a(PROG_ID) -gssapprod -xsapgw21 &
The syntax you're providing refers to UNIX systems, but I did similar thing on our Windows system - I tried all of the following methods (unfortunatelly without success):
rfcexec -a(PROG_ID) -gssapprod -xsapgw21
full_path_to_rfcexec.exe -a(PROG_ID) -gssapprod -xsapgw21
rfcexec -a(PROG_ID) -gssapprod.domain -xsapgw21
full_path_to_rfcexec.exe -a(PROG_ID) -gssapprod.domain -xsapgw21
Can you advise me what to do now?
Thanks

Facing problem with RFC connections

In the Maintenace View for RFC connections, when I press the 'Apply' button I am getting the message"You have no authorization to display the destinationu201D for all the 4 destination IDs"
Can somebody suggest on how to overcome this problem?
Thanks,
Mohammed Tauseef Ahmed

Hi
The message over here means the user with which you are logged into the control system and the CPIC user that you may be using to create RFC destinations to the other systems in the landscape do not have the right authorizations.
It is recommended that all the users have the role TDMS_USER (atleast) or TDMS_MASTER assigned to it.
Once the role is assigned it will work fine.

Adobe Flash Player 9 was previously installed with elevated permissions

I have had to disable flash on our websites in order to make
them useable. Looks like flash 9 was updated yesterday and now pops
up a dialog asking to be reinstalled with admin privs. Considering
no one on aprox 250 machines has admin privs, I am now faced with
the task of spending 15 minutes installing and or upgrading flash
on 250 pcs.
THIS IS NOT ACCEPTABLE. what kind of QA did you do on this
release, because im pretty pissed right now.
I have tried the fix located here: (
http://dontpokebadgers.com/axaa/
) which approves the classID, but this does not seem to work. I am
sure other people must be experiencing this issue. I require you to
perform one of the following actions:
1) Provide a method to disable auto updating the flash active
x control
2) Provide group policy settings that will enable seemless
installation in the background. This would ideally be registry
based and not have anything to do with an MSI file that I would
need to bundle into a startup script.
3) Roll back flash to a working version that does not have
this horrible bug
4) Silently fail to update flash, as the old flash still
renders the content after the error message has been cleared.
Please respond ASAP. I am sure you are about to get a flood
of complaints as you have now changed the default behavior of the
flash player, which unfortunately, much of the internet now
uses.

There already is a method for disabling auto-update, as well
as control over many other options for your users... So this isn't
a bug at all. This is auto-update doing what it's supposed to do.
As the network admin you have to disable it.. Read on...
First, as a network install you should be using the (free)
licensed distribution version of Flash Player. The licensing is
here:
http://www.adobe.com/licensing/
That will get you EXE installers for your network if you want them.
Most importantly it gives you the legal ability to distribute the
player and then control it using the following....
Flash Player Administrator's Guide:
http://www.adobe.com/devnet/flashplayer/articles/flash_player_admin_guide.html
Also please keep in mind that these forums are not official
support channels. They're peer-to-peer support. So in the future
please go through
http://www.adobe.com/support/flashplayer
for needs such as this. We do offer support to network admins
supporting the install...

Can Oracle HTTP Server 2.0 be installed with Oracle App Server 10.1.3.4.0?

Or I guess a related question is what version of apache comes with the latest App Server Patch Set (10.1.3.4.0)?
We are running OAS 10.1.3.3.x and we are having issues with URLs that end in a number but which have query parameters at the end.
E.g. http://<stuff_here>/1?type=table&format=html
The URLs come from REST-ful GET operations. It seems like the HTTP server just ignores the query parameters completely.
When we run against stand-alone OC4J which includes an embedded HTTP server, such URLs work as expected.
We are hoping that perhaps the latest patch set for the full Oracle Application Server 10g will overcome this issue.
But if we need to move to a later Oracle HTTP Server (like the one that comes as an option for the Oracle 11g database installation) we would be willing to do so.
Comments related to this are welcome.
Thanks
Jim

Hi,
Does anyone have experiece getting Apex working with secured BI publisher?
The error I am getting when PDF printing from Apex to BI pub is:
"ORA-20001: The printing engine could not be reached because either the URL specified is incorrect or a proxy URL needs to be specified.
Error failed
OK "
Please note, network services in 11G are already configured; thus I am able to print from Apex to non-secured BI pub.
Thanks,

Cannot connect to Internet wirelessly or with wired connection

Hi!
I have a wireless linksys router connected to a wired linksys router (for vonage). My PC is wired to the wireless router and works fine. My Powerbook G4 was working fine on the wireless network too.
Then, I decided to try to add an Airport Express just for streaming music (it is not wired to the wireless router). I have messed something up. Now, even with the AE unplugged, I can log onto the Linksys network, but the Internet connection does not work. Also, when I Turn Airport Off and wire directly into the router from my G4, I cannot use the Internet.
I've restarted everything I can think of. Any ideas?
Thanks!

Sounds like you need to restart the modem and hard reset the Linksys router which is connected to it. Then reconfigure that Linksys router and verify connection (Ethernet and/or wireless). After you get that setup you can add the other devices.

Where I have to install the Hybrid Connection Manager

I got to connect to a database on-premise with the Hybrid Connection.
I have installed the "Hybrid Connection Manager" locally into the SQL Server.
But I don't know if it is correct.
If I have several DataBase servers I have to install the "Hybrid Connection Manager" locally into each one of them, or I can use another server to install the controller?
Now I want to connect a webService on-premise with the Hybrid Connection. I don't know where I have to install the "Hybrid Connection Manager". In the web server? I have tried it, but the install not Works properly.
Thanks,

CS5 for Windows can only be installed on Windows operating system.
You would need to purchase CS5 for Mac OS.
Given that CS5 is now 4 versions back, it's unlikely you'll find a copy.
You could get DW CC from the Creative Cloud which supports both Win/Mac platforms.

Error when opening an RFC connection (LB : Hostname or service of the messa

Hi All,
Im trying to transport datasources in BW, they are 7.x RSDS datasources. but we did not change the source system, it was existing and we are using the same source for older BW version. we now installing new BW 7.x system.
These transports went fine in BQ system but failing in BP system with the below error :
Error when opening an RFC connection (LB : Hostname or service of the message ser
Error when activating DataSource 2LIS_17_I0NOTIF RP1CLT100
Error when opening an RFC connection (LB : Hostname or service of the message ser
Error when resetting DataSource 2LIS_17_I0NOTIF RP1CLT100 to the active version
the datasource 2LIS_17_I0NOTIF is active in RP1CLT100 system. when this transport goes to prod it tries to overwrite the existing one, as there are no changes to the datasource the structure will be the same.
but after that it cant able to activate that datasource.
so my question is can we able to activate this datasource in RP rather than doing transport again from R/3 Dev---R/3 PRD.
i tried RSDS_DATASOURCE_ACTIVATE_ALL but it doesn't help.
another question is when we migrate from 3.x datasource to 7.x, does this change any metadata in R/3 system as well.
Best Regards
Robyn.

Hi Rizwan,
Looking at the error message it seems like there is some issue with RFC connection and whatever objects you are trying to move are not reaching to target system. Just have a check with basis team.
Once you migrate DS from 3.x to 7.0 yes there will be some meta data changes e.g. the DS type will be changed from ISFS to RSDS. You will have to send the migration along with current data source.

Durgesh.

Error 'Program not registered' while testing RFC connection PI_RFC

Hi Basis Experts
I am having problems while testing an RFC connection PI_RFC in one of our PI quality system.
Here is the Error log
Logon Connection Error
Error when opening an RFC connection

We tried restarting the JCO-RFC provider service in VA,also tried restarting the Gateway service, tried registering the RFC using below command
rfcexec u2013g PI_RFC -a bp1xeuaa202 -x sapgw01
rfcexec u2013D PI_RFC
the command didnt gave any output also in SMGW tcode we didnt get the entry(PI_RFC) under system type as registered server.
Also we tried changing the Gateway hostname and service name in SM59.
Still we are facing the same issue, can anyone please help us in resolving this issue.
Regards
Syed

Hi,
It seems to like problem with your program is not registered. As suggested by spantaleoni, you can go through.
Here Program Id must be case sensitive. Once again check with your program Id.
And, you have to register your program id in Visual Administrator.
Goto Visual Administrator:
In that Select Cluster>Server>Services-->JCo RFC Provider
Then enter the Program Id and gw host & service.
Hope this helps to you.

P.Rajesh

Error in the RFC Connection

Hi Expert,
First, I'm sorry if I post in the wrong thread.
I have a problem when creating RFC Connection. I want to create RFC Connection between BW systems to R/3 System in SM59.
I already insert the right IP Address to the target system, but when I test the connection, I got this error :
host name 'SAP-BO-01' unknown / CPI-C error CM_PRODUCT_SPECIFIC_ERROR
I already test the connection from BW to R/3 and vice versa, using ping in command prompt, and I got no problem. Also, I already create a log on to the target system, and it was successful, but the RFC Connection still error.
Did you have any clue or solution about this?
I really appreciate every helpful comment from you. Thank You...

Hi
Do you have mapping in the host file in the server? ask you basis team to check that.
If you can ping the server, that means connection is fine, only thing is there might be some entry missing in hosts or services file in the server.
During creation of RFC connection you can directly use the IP address also. as you said you are able to ping the server that means you got to know the IP address. Now use the below command to know the exact hostname.
ping -a <IP_ADDRESS>

Anindya
