Error in wizard to create new RFC model: connect to message server failed

Hi,
I am trying to create a new RFC model in my Web Dynpro project in NWDS. In the wizard, I reach the step where I am required to enter the SAP login information. I then enter the details in the Load Balancing tab and click Next. The error message I get is:
Connect to message server failed
Connect_PM MSHOST=****, R3NAME=*, GROUP=**
LOCATION CPIC (TCP/IP) on local host ***
ERROR service '***" unknown
(Note: the *** are client-specific and therefore confidential info so I am removing them).
The thing is, a colleague of mine is also doing the same thing, but he is not encountering this error.
Can someone help me troubleshoot this?

Hi
The user you use to connect in the RFC should have the authorization to S_RFC. In the Duet installation guide look for the section about defining a system user ID in UME. This section has details about the authorization required for the user.
Thanks

Vipin,
I don't have access to our firewall myself to confirm what ports and services we opened (I worked with our Network Operations team to get this done), but if I recall correctly, it was pretty limited, just http and https over tcp ports 80, 443, 8100, and 8101. Probably could even restrict that to just https over 443 and 8101. However, from your configuration, you don't yet have your web dispatcher configured to talk to your message server over https, only http. I would recommend that you get the web dispatched completely configured and working in as close to your final desired configuration as possible while keeping it inside your firewall, not your dmz. Then move it to the dmz and see what breaks, and that way you know it's just the firewall that needs configuration at that point.
To configure the SSL termination, the following are the parameters required and the way that I configured them in our scenario (which terminates incoming SSL requests and re-encrypts them when sending them on to the backend, and also uses SSL for message server communication):
rdisp/mshost = mshost.domain.org
ms/https_port = 8101
wdisp/server_info_protocol = https
wdisp/group_info_protocol = https
wdisp/url_map_protocol = https
icm/server_port_1 = PROT=HTTPS,PORT=443,TIMEOUT=30,PROCTIMEOUT=600
icm/server_port_2 = PROT=HTTPS,PORT=8101,TIMEOUT=30,PROCTIMEOUT=600
icm/host_name_full = wdhost.domain.org (note, use the externally visible name as registered on your SSL certificate for web dispatcher here; does not need to match the actual machine hostname, but must be resolvable in external DNS)
icm/HTTP/admin_0 = PREFIX=/sap/admin,DOCROOT=\usr\sap\RW1\W00\data\icmanroot/admin,AUTHFILE=\usr\sap\RW1\SYS\global\security\data\icmauth.txt,PORT=8101
ssl/ssl_lib = $(DIR_EXECUTABLE)\sapcrypto.dll
ssl/server_pse = $(DIR_INSTANCE)\sec\SAPSSLS.pse
ssl/client_pse = $(DIR_INSTANCE)\sec\SAPSSLC.pse
wdisp/ssl_encrypt = 2
wdisp/ssl_auth = 1
is/HTTP/show_detailed_errors = FALSE
wdisp/permission_table = $(DIR_INSTANCE)\sec\ptab
On the backend host I have the following parameters:
sec/libsapsecu = \usr\sap\RP1\DVEBMGS00\exe\sapcrypto.dll
ssl/ssfapi_lib = \usr\sap\RP1\DVEBMGS00\exe\sapcrypto.dll
ssl/ssl_lib = \usr\sap\RP1\DVEBMGS00\exe\sapcrypto.dll
ssf/name = SAPSECULIB
icm/server_port_2 = PROT=HTTPS,PORT=443,PROCTIMEOUT=-1
ms/server_port_1 = PROT=HTTPS,PORT=8101
Naturally, a server certificate is configured on the backend that the web dispatcher trusts (it can be an internally generated certificate; the outside public just needs to trust the web dispatcher's certificate, so that one should come from a recognized CA). Port 8101 is NOT open from the outside, just from the dmz and only to/from the web dispatcher host (this does allow me to use the webadmin interface from the inside). The https service also has to be activated on the backend in SMICM.
There's good advice about security setup for the web dispatcher in Note 870127, and troubleshooting advice in the Note mentioned in your tracefile output, 552286. Fairly complete documentation is in the online help at http://help.sap.com/saphelp_nw70/helpdata/en/de/89023c59698908e10000000a11402f/frameset.htm. Note 538405 is also good, more for performance configuration than security.
I hope you find this helpful.

Unable to Create New Data Model

Hello all,
I have been using BI publisher 11g for sometime but at best can be treated as a newbie. I was able to create New data models, reports, layouts etc till sometime ago.
Now when I try to create a New Data Model I get an error message saying
Unable to load ~weblogic/usr/temp/xxxxxxxx.xdm
I click on Ok and create my data set using the SQL query.
Now when I try to generate a sample xml I get the following error message:
org.xml.sax.SAXParseException: : XML-20108: (Fatal Error) Start of root element expected.
I understand something has changed in the server but I cannot pin point what and where.
Any help will be highly appreciated.....
Thanks,
Geetesh

The JDK/Java that ODI using should be 64bit if ODI 11.1.1.6 is 64 bit. (I think JDK 1.6 is recommended for this ODI version)
Also, for which technology you are creating a data server ? and what error message you are getting while creating it ?
Thanks,
Santy.

Adil,
There could be many reason like IIS issue, Space issue, Permission issue, SQL issue which is not possible us to guess rather
you need to jump in the SharePoint log(Program Files\Common files\Microsoft Shared\Web Server Extensions\14\LOGS) and find out the specific error log its throwing after which trouble shoot can be start.

1) As no role wtih name LcrInstanceWriterLD was existing in the server ,hence created a new role with same name and assigned the LCR related action . Assigned the role to the user through which we are creating JCOs.
But we still getting the same error.

Poonam

Hi Poonam!
Got to dig in the past a bit, I remember Users being able to create SLD object have to have certain permissions set in the J2EE UME. Simple Admin rights do not suffer, if I recall right.
Unfortunately I cannot go further in detail because this issue has been solved by a long gone collegue of mine.
Good luck anyway!

Hi Uday,
you have to create a logon Group named PUBLIC with Transaction SMLG in your Backend system. Also don't forget to add the line:
sapmsXYZ <port_number on which XYZ listens>/tcp <For ex: 3600>
to your services file in C:\winNT\system32\drivers\etc (for the Windows 2000 system). XYZ means your Instance Name.

MSN Messenger 7.5,Connection Troubleshooter
Reason and Prerequisites
The reason for this malfunction is, that the datatype of the registry value HKLM\System\CurrentControlSet\Services\TCPIP\Parameters\DatabasePath
was changed from REG_EXPAND_SZ to REG_SZ.
The following programs are currently known to cause this registry change:
Starting MSN Messenger 7.5 "Connection Troubleshooter" (Build 7.5.0299).
Installation of MSN Messenger 7.0 or MSN Messenger 7.5 with the option automatic scanning and configuration of ports.
This modification prevents the expansion of environment variables in the value of the parameter. Therefore,
      %SystemRoot%\system32\drivers\etc
is not translated to
   c:\windows\system32\drivers\etc
and the services database is not found by the API function getservbyname().
If you have checked the datatype of registry value DatabasePath and it is REG_EXPAND_SZ, apply SAP Note 52959 to check the appropriate settings in the services file.
Solution
Start the registry editor and rename the registry value HKLM\System\CurrentControlSet\Services\TCPIP\Parameters\DatabasePath
Create an Expandable-String Value (REG_EXPAND_SZ) with the same name and value.
If more PCs are affected, you can export the correct value to a .reg file and import the .reg to other PCs.
If you have the same problem although you have not installed Microsoft MSN Messenger 7.5, create a customer message, collect the following information and attach it to the message according to note 541726 or upload it to sapservX (see note 40024):
Scan your workstations for spyware and viruses with up-to-date virus definitions. If you already did that what was the result ?
What software has been installed recently ? (client software, Firewall)
Create a registry export of the following key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstallon the affected and the unaffected PC respectively and attach the two .reg files to the customer message.
Are the users on the affected workstations logged on with administrative credentials (local administrator ) ?
Create an MPS Report Networking and Setup Perf of an affected workstation so that we can check if they use an software in common.
You can download the Networking MPS Reporting Tool at:
http://download.microsoft.com/download/b/b/1/bb139fcb-4aac-4fe5-a579-30b0bd915706/MPSRPT_Network.exe
You can find a short description about the features of the tool at:
http://download.microsoft.com/download/b/b/1/bb139fcb-4aac-4fe5-a579-30b0bd915706/MPSRPT_Network_Readme.txt

http://download.microsoft.com/download/b/b/1/bb139fcb-4aac-4fe5-a579-30b0bd915706/MPSRPT_SETUPPerf.EXE
Run this report too on identically configured workstations, which are not affected.
If you have already changed back the DatabasePath parameter and if after a while the value was switched back to REG_SZ perform the following steps to help us to identify the reason for this problem:
Switch the datatype back to REG_EXPAND_SZ
Download Regmon from http://www.sysinternals.com on the affected machines
Enable auditing on the affected clients
Modify the settings of the eventlog so that no important entry is deleted!
Open Regedit and highlight HKLM\System\CCS\Services\TCPIP\Parameters
Right-click on "Parameters" and choos "Permissions" and click "Advanced".
Choose "Auditing" and "Add".
Add "Everyone" and select "this key only" under "Apply onto".
Check the boxes "Set Value" and "Delete" and click "OK".
Apply these settings
Start Regmon and apply the correct filter settings:
Press the "magnifying glass" button to stop the monitoring.
Press the rubber button to delete all logged entries.
Go to "Options Filter/Highlight".
Copy the following value to the include field: tcpip\parameters\databasepath and click "Apply".
Start Regmon by pressing the magnifying glass button
Verify that logging starts when you double-click the TCPIP Key in regedit!
If the datatype will be changed again, provide us the output of the monitoring tools.
Solution provided by Microsoft
This issue is said to be fixed as of build 7.5.0311 of MSN messenger.

How do I get connected to a server on my network via an IP address? When I try to open in a URL and login as a registered user with proper login it errors out saying there was a problem with connecting to the server?

I am new to Mac...How do I get connected to a server on my network via a hyper link IP address path? When I try to open in a URL and login as a registered user with proper login it errors out saying there was a problem with connecting to the server?

Some of the following is going to use some technical terms — this area is inherently somewhat technical.
If you don't understand some part of the following reply, please ask.
Is this your own OS X Server system on your own network, or is this some other server within some larger organization?
You're posting this in the OS X Server forum, which is a software package that allows OS X systems to provide web-based and many other services; to become servers.
If it's your OS X Server on your network, then the network and DNS configurations are suspect, or the server is somehow malfunctioning or misconfigured. This is unfortunately fairly common, as some folks do try to avoid setting up DNS services.
If it's a larger organization and somebody else is managing the server and the network, then you'll probably need to contact the IT folks for assistance; to learn the network setup and DNS requirements, and if there's a problem with the server itself.
The basic web URL "hyper link IP address path" — without using DNS — usually looks something the following, where you'll need to replace 10.20.30.40 with the IP address of your server:
http://10.20.30.40
UptimeJeff has posted a URL that specifies the AFP file system; an OS X file share. That's used if you're connecting to an Apple storage service somewhere on your network. You might alternatively need to specify smb://10.20.30.40 or such, if it's a Windows file server. (There can be additional requirements for connecting to Windows Server systems, too.)
If there's local IT staff available here, please contact them for assistance. If these are your own local systems and your own local OS X Server system, then some information on the server will be needed.

Load balancing error 88: Cannot connect to message server (rc=9)

Hi,
We are facing a problem in the system object.
initially we created a system object with loadbalancing template ,and everything worked fine, but after couple of months we found a error "Load balancing error 88: Cannot connect to message server (rc=9)", so we have created a Dedicated application server object which resolved our issue.
My question is why has this problem occured, and since my client side has lot number of users and we wish to keep the system back to load balancing object.
How can i make my system object work back, what might be the causes?
Thanks
Srivastsa Kondapally

Load balancing only works if the message server is available and the logon group specified exists as well. If one of those changes, then it will break until you get the values set correctly.

HT2480 Ipad mini - exchange email stopped working randomly Error: "Cannot get mail. The connection to the server failed."

I got an iPad mini over Christmas and have had no issues setting up/managing my email until yesterday. I've had my Exchange email working for almost a month, and yesterday I stopped getting emails and getting the error: "Cannot Get Mail. The connection to the server failed."
I tried resetting the device (multiple times) and deleting and recreating the Exchange account (multiple times). This is getting annoying because it worked fine up until yesterday. I'm not aware of any updates to the device, or any changes that have occurred since yesterday.

Due to a screen issue, I had my iPhone 5 replaced two days ago. I repeated deleted the mail account and kept adding it but this did not make any difference. When I attempted to setup the new phone with my Google (Gmail via exchange active sync) accounts I was receiving this same "Cannot Get Mail" error. From what I was able to gather, this problem should be affecting Gmail accounts set up via Exchange. When originally purchasing the phone I was assisted and directed to set up my Gmail account through Exchange because it had the ability to use "ActiveSync" and push not only mail and calendars, but all of my contacts as well. I found this article regarding the subject.
http://www.pcmag.com/article2/0,2817,2413283,00.asp
What it came down to was having to delete my Gmail via Exchange account and separate it into two different accounts, a regular gmail account for my mail and a CardDAV account for my contacts.
Here is what I did. Google is changing their system and for new registrars Exchange ActiveSync will not work so you will be unable to register your account via Exchange and have your mail, calenders, and contacts all pushed together. I find this change really annoying. If you are having problems accessing your contacts after deleting the mail account, like I was, here is the work around.
To circumvent this issue go to Setting > Mail, Contacts, Calendars > Add Account > Other > Add CardDAV Account: Under server ender google.com, then your email user name and password, then click next to verify the information.
I hope this helps.

How to resolve "Connection to LDAP server failed." error?

Hello,
I have installed Coldfusion8 on one of my server that was having ColdFusionMX earlier.
The ColdFusionMX admin settings are automatically transferred to the new Coldfusion8 admin page after installation.
Also I have configured all my websites at the time of installation.
After all when I am trying to login into one of my website system is throwing the below error.
"Connection to LDAP server failed."
Prevously it was working well with coldfusionMX. After installed Coldfusion8 I am facing this problem.
Is there anything to do more with cf admin settings page or is this problem is with the code? (Infact I havent modified my cfm code)
Please find the piece of code that I am using.
<cfldap action="QUERY" server="#application.LDAPServer#" port="#application.LDAPPort#" start="#application.LDAPBase#" name="search" attributes="alias, dn, uid, technicalCareerLevel, locationorgunit, givenName, sn" filter="#filter#" scope="SUBTREE" maxRows="2">
Anybody can assist me on this?
Thanks in advance.
Manoz.

I have fixed this problem successfully.
The problem was with the referral attribute of the cfldap tag.
After adding this (referral="yes") attribute to my code I am able to login into my website.
<cfldap action="QUERY" server="#application.LDAPServer#" port="#application.LDAPPort#" start="#application.LDAPBase#" name="search" attributes="alias, dn, uid, technicalCareerLevel, locationorgunit, givenName, sn" filter="#filter#" scope="SUBTREE" maxRows="2" referral="yes">
Any way thanks for your assistance!!!!!
