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.
Regards
rajeev
hi,
I think no problen with the mapping part,
jco connection requird when xi try to stablish the connection with the adapter .
please look the link provided.
Setup and test SAP Java Connector outbound connection
please also check the following parameter at the exchange profile
com.sap.aii.rwb.server.centralmonitoring.r3.ashost
com.sap.aii.rwb.server.centralmonitoring.r3.client
com.sap.aii.rwb.server.centralmonitoring.r3.sysnr
com.sap.aii.rwb.server.centralmonitoring.httpport
these parameter must be given properly.
if every thing is ok than and problem still exist than try to restart the system.
for us after restarting its worked fine.
regards,
navneet

"COMMUNICATION FAILURE" during JCo call. Error opening RFC connection
Hi
I am trying the following scenario

In SM 59 test connection of AI_RUNTIME_JCOSERVER throws error " Error opening RFC connection"
Do I need to activate any service in SICF and do I need to do any IE configuration (sxmb_adm)
pls let me know the steps to solve this
thanks
manianHi Manian,
pls chk with ABAP system tha tu have given the correct PWD and CLNT No
Use
You need to create the following RFC destinations with both transaction SM59 (ABAP) and the Visual Administrator (Java):
● AI_RUNTIME_JCOSERVER
Points from the Integration Server to the mapping runtime. The program ID corresponds to the entry under JCo RFC provider for the J2EE Engine (used for the mapping runtime, value mapping, and the exchange profile).
● AI_DIRECTORY_JCOSERVER
Points from the Integration Server to the Integration Builder. The program ID corresponds to the entry under JCo RFC provider for the J2EE Engine (used to refresh the runtime cache).
● LCRSAPRFC
The RFC destination LCRSAPRFC is required for the connection to the System Landscape Directory (SLD). It is used to read the exchange profile.
● SAPSLDAPI
The RFC destination SAPSLDAPI is required for the connection to the SLD. It is used by the ABAP API.
Depending on your client settings, it may be necessary to log on to your Integration Server host as SAP system user with the authorization to maintain customizing tables and to release transport orders.
User SAP* or DDIC does not have these authorizations
Thanx

"SYSTEM FAILURE" during JCo call. max no of 100 conversations exceeded
Hi Experts,
My scernario is : RFC->File Asynch
When i do testing this scenario in Configuration (ID) -> tools-> test configuration I got below error.
Interface Mapping
Runtime error

2) In sender RFC communication channel i have all correct parameters like: gateway service,Program ID, client number, password, userid etc
Pleas help me out.
thanks
siva grandhihi,

Hi All
I have developed Java mapping program where I am calling three BAPI in sequence and trying to map all three bapi data to single Target XML file or Multiple target xml files depends on the in coming data.
Now I want these files name should be genereted dynamically .So I have used below Dynamic Configuration code in my java mapping program.********************************************************************************************************************************************************************
try
String currDate = new String();
String currTime= new String();
DateFormat dFormat=new SimpleDateFormat("yyyyMMdd");
DateFormat tFormat = new SimpleDateFormat("HHmmss");
java.util.Date date = new Date();
TimeZone cetTimeZone = TimeZone.getTimeZone("CET");
tFormat.setTimeZone(cetTimeZone);
currDate = dFormat.format(date);
currTime= tFormat.format(date);
String pubDate=currDate + currTime;
String ext=".xml";
String event="-1_1-";
trace.addInfo("******** Before Dynamic Configuration ***************" );
DynamicConfiguration conf =(DynamicConfiguration)container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create( "http://sap.com/xi/XI/System/File","FileName" );
trace.addInfo("******** After Dynamic Configuration ***************" );
String tempFileName="NL09-"eventponum+ "-" pubDateext;
trace.addInfo("The name of the file is : " + tempFileName);
conf.put(key, "tempFileName");
catch (Exception e)
trace.addWarning("Error While creating File Name"+e.getMessage());
throw new Exception("Error While creating File Name",e);
Now the problem is when I am using above code I am getting following error
"SYSTEM FAILURE" during JCo call.
java.lang.reflect.UndeclaredThrowableException

Could please tell me why I am facing this problem only when I am using Dynamic configuration code.
If I dont use Dynamic configuration code then I am not getting any error .But my requirement is to generate dynamic file name (Note I have tried with Variable Substution also, It is also not solving my problem as I need time stamp of ("CET") time zone).Hi Abhishek,
Yes I have appended throws StreamTransformationException and imported the relevant StreamTransformationException class also.
Here I am getting strange thing when I am adding dynamic configuration code " SYSTEM FAILURE" during JCo call. But Jco cal is something to internal systems which does not relate to Dynamic Configuration.
If I run my code with out any Dynamic Configuration code then it is running with out any errors.
But I need this Dynamic Configuration inorder to generate dyanamic file name. -

Java.sql.SQLException: Communication failure during handshake.
I'm troubled by this problem followed:
the exception is decripted as:
java.sql.SQLException: Communication failure during handshake. Message from server: "Unknown database 'cust'"
I'm using JSP to access the MYSQL database. the database server has three databases:mysql,test,customer. my OS is win98. I can access the customer using "mysql -u root -p customer" in the command prompt.
but when I runs the JSP, the error appears.
the connection string is :
private String protocol = "jdbc:mysql://localhost/customer?user=customer_f&password=151276&useUnicode=true&characterEncoding=8859_1";
if the connection string is :
private String protocol = "jdbc:mysql://localhost/test?user=customer_f&password=151276&useUnicode=true&characterEncoding=8859_1";
or
private String protocol = "jdbc:mysql://localhost/mysql?user=customer_f&password=151276&useUnicode=true&characterEncoding=8859_1";
there's no problem.
what is wrong ?
I guess it's wrong with mysql's setting.
please help me,lots of thks.It seems user root is the owner of 'customer' database. Can you use root to access 'customer' from JSP code?
Another hint:
Do you grant user customer_f privileges to 'customer' database when create 'customer'?
with root access from mysql> prompt:
mysql>grant all privileges on customer.* to customer_f@"localhost" identified by '151276';
Then, user customer_f will have all privileges to access 'customer' either from prompt or JSP page.

Hi All,
I am getting error while executing oDATA service from SAP Netweaver Gateway
Error details:
RFC call ended with "Communication Failure" exception (Function call failed; could not find the function
I am using SAP NG 740
Project is created in Gateway system using SEGW having Map to Datasource option used.

I had tried all troubleshooting like delete and add service and alias in "/IWFND_MAINT_SERVICE".
but still getting same error for all service.
Kindly advise.

VivekHello Vivek,
Service builder would have also generated code for RFC Exception handling to catch exceptions raised when communication fails between your GW and BE for some reasons.
Handling is done for 1. System Failure 2. Communication Failure & 3. Business Failure;
Put a BP in your DPC or DP_EXT class where exception code is written to check what exactly is has caused communication failure.
Check if that RFC is existing in that destination or not.
For your reference : Code would be something like this. Put BP here and check the problem.
* Error and exception handling
IF lv_subrc <> 0.
* Execute the RFC exception handling process
me->/iwbep/if_sb_dpc_comm_services~rfc_exception_handling(
EXPORTING
iv_subrc = lv_subrc
iv_exp_message_text = lv_exc_msg ).
ENDIF.
Go inside this method and check to get info on what has to be done to resolve issue.
Check carefully what has gone wrong and fix it accordingly.
No need of adding service & deleting as problem is not because of that.

Error while loading services: Failure in Loader: VerifyError: Error #1014
I have a library that, after it loads, I see this error in the console:
Failure in Loader: VerifyError: Error #1014: Class mx.collections::ArrayCollection could not be found.
I had the same problem with another library, except it had a problem with IToken. I got around this problem by changing the default linkage of libraries in build path from external to merge into code. That did not work this time.
Merging Flex libraries into service libraries does not seem to be anything close to the correct way to deal with this. Besides, it didn't some the problem every time.
What is the best way to keep these sorts of dependency errors from arising? The RSLs are included with Web apps, but not with libraries.I have found what happened.
I created a library and created a data model within it. I created some entities within the data model. Some of those entities had collections as properties. I created the ActionScript code for the model and the collections were ArrayCollections. I moved the interfaces of the created code to a separate library.
The interfaces need to be changed from using ArrayCollection to IList. I knew enough about that to change it for the service I was trying to bring into my application. I missed another interface that had ArrayCollections as properties and that caused the error.
After cleaning up all of the ArrayCollection references from the interface library my service loaded.
The Hello Gravity video tutorial has a very good explanation on why specific implementations of Flex classes are not used in service interfaces: http://blogs.adobe.com/gravity/2011/09/09/hellogravity-sample-application/ -
Sync Web Service - BPM with 2 sync proxy calls error.
Hi.
Have a sync web service going into a BPM.
In the BPM there ar 2 sync calls towards a system making a credit check.
The answer is responded to the web service.
In our QA system the solution works perfect.
I transported the solution to production and when I test the web service call towards I get the following error.
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>

When I check my config everything looks the same.
Looks like we never send the first sync call to the proxy when I check in SXMB_MONI and the BPM gets terminated.
We have just migrated the solution from XI 3.0 to PI 7.11.

KalleHi.
How will that help if we do not send the message.
When I check the graphics in SXMB_MONI the error occours befor we send the first message with proxy.
Also extend ASYNC timeout?
We are using sync communication.

Hi, experts:
I got a problem when calling a RFC from EJB by using JCO object.
Sometimes JCO return last calling result, and when i manual calling again. JCO return correct value.
How to reset connection?
Thanks for any hints.
Best regards,
Nick.<div style="text-align:left">But another situation happen that is sometimes JCO return empty result.
Could it be previous release action to made next time calling fail?</div>
Hard to comment without knowing details. Assuming that all your calls are made in a new context, the connection should be kind of stateless. However, in theory you could of course have an RFC function that behaves different over time or where it runs (application server), etc.; in practice though this is unlikely.
To better understand what's going on I'd recommend to activate tracing. You can set the trace level by passing the command line argument -Djco.trace_level=N (where N is between 0 and 10, 10 being most detailed trace) and -Djco.trace_path=<path> to your java executable (or however you want to accomplish that on your J2EE server).
In addition it might help to also activate tracing for the executed RFC calls by setting the environment variable RFC_TRACE=1 and if more details are required RFC_TRACE_DUMP=1.
Maybe there's some silly problem and the request parameters are different or not as expected... -
Random JCO Communication Failure Error after Hardware Migration
Greetings experts,
we had a migrated our XI server to new hardware and had couple of SLD related issues which were solved by the migration team. However, we are getting JCO communication failure very frequent whenever we use JCO from JAVA to call an RFC. The weird thing, if you restarted the message it will be successful.
The error message in the message monitor :
"COMMUNICATION FAILURE" during JCo call. Error opening an RFC connection"
Any idea to solve this random issue?Hi again,
the number of connection was increased to 200 but with no effects. Also, the user used to connect is a system user which does not need a ticket.
This is my connection code
mConnection = JCO.createClient("600", // Client
"USER", // Username
"PASSWORD", // Password
"EN", // Language
"hostname", // Host
"01"); // System Number
do I need to add anything else if I am using a clustered system? -

device will not scan to computer. returns "error occurred while communicating with scanner". this error returns from the print/scan settings, from image capture and from the HP scan utility. the printer will copy so the scanner will function to some extent. it is brand new. on a wireless network. prints fine
OS is fully up-to-date, drivers are current, downloaded from HP and installed rather than using CD. device has been unplugged from wall, computer restarted, printers cleared and reinstalled.
any other ideas?
some more info...
if a sheet is placed in the scan feeder, the scanner illuminates and makes a ping sound.
firewalls are off

HP Utility does not have a Scan section. HP Utility Applications has Scan 3. this does not workHi BetterL8,
I understand your frustration. The software you are using was designed for the older operating system not for Mavericks. There has not been software released for the c310 that is compatible with Mavericks therefore, you will be using the Apples Print and Scan not the HP Scan. Because you have this old software still on the computer, I recommend you uninstall it and download the Apple Software Update. Follow the instructions below:
Scrub
Open the Applications folder > HP or Hewlett Packard folder > HP Uninstaller
Click continue, click on one of the printers in the list.
Hold down Control, Option and Command
While holding the three buttons down, Click uninstall.
Reset Printing System
Click the Apple icon ( ), and then click System Preferences.
In the Hardware section, click Print & Fax/Scan. The Print & Fax/Scan dialog box opens.
Right-click (or Ctrl +click) in the left panel, and then click Reset printing system…
Click OK to confirm the reset.
Type the correct Name and Password.
Click OK to reset the printing system. The Print & Fax dialog box shows no printer selected
Note: This will remove all printers in the print and Fax/Scan, any printer removed can be re-added later by clicking the plus (+) symbol
Repair Disk Permissions (this is good measure to ensure non of your permissions differ)
On the Dock, click Applications, and then click Utilities.
Double-click Disk Utility.
Highlight your hard drive/partition on the left (by default this is "Macintosh HD").
Click the Repair Disk Permissions button at the bottom of the window.
Once the repair is complete, restart the computer.
Restart the computer.
Check for apple updates
Connect the USB cable if it is not already connected
Click on the Apple icon
Select Software Updates.
Restart the computer.
Leave the printer on and unplug the power cable, reconnect after 1 minute.
