DNS Alias not Updating on Communication Channel

Hi,
We use DNS Aliases when connecting to some of our servers. One interface connects to a server using FTP with alias FTPServer.
This FTPServer had a site switch over the weekend and the DNS Alias did not update in the communication channel. I had to ping the DNS Alias and put the server name into the CC to get the FTP to work.
Is there any way of getting PI 7.1 to refresh the DNS?
Thanks,
Gareth

  • JDBC adapter type  not visible in Communication Channel

    Hi All,
    I have deployed JDBC driver according to http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/00b4a020-4ae6-2c10-5a95-fed4ad9a4b60?QuickLink=index&… .
    Driver deployed successfully and I have checked it in folder \usr\sap\xxx\DVEBMGS30\j2ee\cluster\bin\ext\com.sap.aii.adapter.lib\lib and it's found ok. But this adapter type  not showing in Communication Channel only RFC and SOAP are showing there. I have restarted the server also. Can any one tell me where the problem is?

  • IDOC adapter is not shown in communication channel

    hi gurus,
    at present i am using PI and in the communication channel list (adapters types) no idoc adapter is displayed ,can anyone help me to solve this problem.
    and also when i create any scenario related to idoc those messages where not displayed in communication channel.

    Hi Allen,
          U r checking for an IDoc channels in Communication channel monitoring.IDoc adapter is reside in ABAP stack.So that u cant see the Idoc communication channels from monitoring of CC's. If Idoc messages is at sender side no need of CC.
    If you want to view the source and target messages of Idoc's u can see those from SXMB_MONI.Choose u r processed message,Dbl click,For Idoc as sender u can view the message from payloads of Inbound message,For Idos as Receiver u can view the message from Payloads of Request message Mapping.
    Hope it will helps..
    Cheers

  • Unsolicted update in communication channel

    I received a counter update in my communications channel for the following post: https://forums.oracle.com/thread/2569282
    I'm neither tracking or following the discussion or space and I have not been participating in that discussion. I also have not accepted (ignored) any friend requests. Thought I just let you know in case this might indicate a more general issue or bug.

    A very successful person once told me "Stop doing it if it is no fun any more."  This was after he sold his stable of Ferraris.
    There does not have to be a strong link between quality software and large organizations.  In fact, there might be some negative correlation.  There has to be a strong sales organization and strong marketing.   There is little feedback from the technically astute users to the decision makers.
    Linkedin, Facebook, and yes, Google all put out some garbage.  I think the "new development paradigms" turn programmers into amateurs.  (The google groups UI has some obvious goofs - favorited groups don't get bolded to indicate new messages until after you look at the group, the reply editor quoting adds a ridiculous amount of blank lines, search totally borked, and on and on.)  There's also a shininess factor - when something is new and shiny, people may give good feedback, developers crank out great stuff, but once the money's been shoveled in, bloat happens, as well as a push to mediocrity.

  • Issue with updation of communication  channel

    Hi Experts,
    I have configured a   JMS  to Proxy scenario in XI system. i  have changed  the  "Queue name" parameter   in  sender communication channel for the JMS adapter. the new Queue name is not  being used by the interface.
    when i monitor the messages  for the  this interface, i found that system is still using the Old  Queue name.
    can you please suggest  a way to resolve this issue.
    -Kaushik

    Hi,
    I am not sure if this resolves the issue.
    Stop the channel using RWB>Adapter Engine>Communication Channel Monitoring
    Identify your JMS sender Communication channel and stop it.
    Go to ID and reedit this channel and activate.
    Comeback to previous Communication Channel Monitoring check the status of activated Communication Channel (start it if it is still in stopped mode)

  • Communication Channel Monitoring not showing up Communication  Channels

    mmm it seems I spoke too quickly, things seems to work as expected now. I don't know what I did change since.
    I've retested between two cards: it seems also ok except 2 strange things:
    - when CAN2 is physically connected on PC2, it seems CAN1 that listens instead (as if CAN1 was connected)
    - trames sent from CAN0 and CAN1 on PC1 seems to be repeated from IXXAT card: they are returning respectively on CAN1 and CAN0.
    Sorry, no idea on these two.  As for the first one, what happens if you connect CAN1 to CAN2 on PC2 (no connetion to PC1)?  I don't know anything about the IXXAT card.  Is there some switch that internally bridges the two ports?

    I used the below code.
    I am not Getting any error, the mapping is successfully ACTIVATED. But in the Receiver field i am Getting Null as output , the DB lookup which i have mentioned is not connecting to the Database and executing and fetching the query. Just inthe receiver field its througing the Null valuse. The Required Value is not fetched by using the communication channel.
    I am getting the above error when i try to TEST THE MAPPING in IR.
    Below is the code i used.

    Regards,

    As i told before i have tested the interface, its not showing any error, its Activated and throwing Null as output.
    Its not fetching the value from database. In CC Monitoring also the adapter is in Green Status. No error over there. Its throwing the output as Null (Default value in the code.)
    Below is the connection parameter i have used:
    DRIVER:com.microsoft.jdbc.sqlserver.SQLServerDriver
    CONNECTION : jdbc:microsoft:sqlserver://<IP>:1433;DatabaseName=test_db
    But in the blog

    If u can see properly, he has mentioed some extra parameters in the JDBC Connection Parameters.
    But the screenshot is not proper so i am not able to see the querry he has used in Connection parameters.
    Please help

  • Configuration Wizard in ID is not using existing Communication Channel

    Hi,
    I am using PI 7.1.
    I created a Communication channel FileSenderCC for a Business System Sys_Sample_One_D with Party as blank.
    After creating i can see below object in the list of communication channels in the left pane.
    |Sys_Sample_One_D|FileSenderCC
    After this when i use Menu: Tools -> Configuration Wizard -> Internal Communication, to configure the scenrio, I selected the Business System Sys_Sample_One_D and Adapter Type "File", and proceed, while selecting the sender communicaiton channel, it cannot find the FileSenderCC that i created.
    If i manually enter FileSenderCC, and complete the scenario, it is creating a new communication channel with the samename, and not using the exisitng one.
    After that i see two communication channels in the left pane.
    |Sys_Sample_One_D|FileSenderCC
    *|Sys_Sample_One_D|FileSenderCC
    does this happen in PI 7.1 only, because when i worked in 7.0 long time back, i dont think i got this issue.

    Hi,
    I had the same issue on PI 7.1, it looks like a bug, but I found no note about it.
    I think you should open an OSS message for this.
    Kind Regards,

  • Runtime Update of Communication Channel Password

    I posted this question in the Security Forum as well as here since I was not sure which was appropriate.
    We have a new application, Password Vault, where the company would like to change all passwords on a daily basis. Password Vault has a Java API that will allow me to obtain the password for a specific account. What I would like to know is whether there is a way in PI to create a module that will be called by the Communication Channle when it requires the password which will aloow me to dynamically pass the password to the Communication Channel.
    In short, I would like to step in front of all runtime password requests and push the current password to the Communication Channel.
    Is this possible and/or where can I go to find more information?

    Ok, we have conceded that until SAP makes a change that allows some sort of hook into the Communication Channel so that we can handle the password we will not be able to implement a "pull" type of change.
    We have code to extract and log Configuration Scenarios, Communications Channels and Interface Determinations. We also have some code modeled after what Bill Li has done to create a Change List and modify the Communication Channel.
    Mostly we need to be able to set a Communication Channel Inactive/Active and change the password.
    The part we are struggling with is the role of the Restricted Communication Channel and how to get the information from and existing Communication Channel into the Restricted Communication Channel which is the only thing we can add to the Change List.
    It seems like there should be some relatively simple way to do the following:
    1. Retrieve a Communication Channel using the API
    2. Build a Restricted Communication Channel object with all of the information in the Communication Channel...we know the password is always returned as null and can handle that issue.
    3. Modify whatever value we want modified
    4. Create a Change List
    5. Add the Restricted Communication Channel to the Change List
    6. Activate the Change List.
    We have no real problems with any of the above except for 2.. How do we build a complete Restricted Communication Channel from the retrieved Communication Channel?

  • File sender Communication Channel is not working

    Hi friends
    we  Created File sender Communication Channel and Activated but It is not picking up file
    1.  0 messages in Message Monitoring
    2. My Communication Channel not appearing in Communication Channel Monitoring also
    3. We have refreshed the cache and activated the channel.
    we chack with File name, Directory name and  path ....
    Friends have any idea
    Regards
       Viswanadh Vadde

    Perosnally, I would recommend setting a trace and letting the system telling you exactly why.
    Traces are used to analyze runtime errors.  By setting a specific trace level for specific locations, you can analyze the behavior of individual code segments at class and method level.  This is done with the help of the log configurator service:
    Log onto the Java Admin Console
    &#61680;     Services
    &#61680;     Log Configurator
    &#61680;     Locations
    &#61680;     Choose the location (Java package) and the tracing level (severity)
    (for example, com.sap.aii.adapter.file)
    &#61680;     Root Location > com > sap > aii > File
    &#61680;     Set the severity and choose Copy Severity to Subtree
