Dispatcher Running; Server could not be connected

Hi
I am trying to install XI3.0 ramp-up version part of which J2EE engine needs to be installed, Everything went on well while Installing until we started doing pre-install configuration to install XI. While updating parameters for JDBC service within the dispatcher, the whole thing disappeared and since then we are not able to connect to the J2EE Administration Engine - neither through IE or through Admin tool (go.bat). Could some plesae help us go past this state.
Thanks
Shiva.

Hello Siva,
Can you try to restart J2EE server from SMCIM (Tool Bar Administration ==> J2EE Server ==> Restart) from SAPGUI front end.

Rajan Kidambi

  • SSRS Report Server Could not establish connection. The underlying connection was closed. Could not establish trust relationship for the SSL/TLS Secure channel

    Hi
    Had to un-install and then re-install MS SQL Server 2012 with SSRS.
    After we re-installed we are able to get to the Web Services page but not the Report Server page and get the above error message. We need to use SSL and when we bind the cert in RS Configuration Manager it says it does this successfully on the WebServices
    tab. We also do a similar exercise on the ReportServer page. 
    Any help warmly welcomed :D
    Thanks

    Hi Rich Whight,
    According to your description, after you re-installed SQL Server 2012 with SSRS, you are able to access Web Service URL, but when you tried to access Report Manager URL, the error occurred: The underlying connection was closed. Could not establish trust
    relationship for the SSL/TLS Secure channel.
    The issue may be caused when the certificate isn't installed correctly in the trusted root for the local computer. To verify and install the certificate, Please refer to the steps blow:
    In RsReportServer.config file(default location: C:\Program Files\Microsoft SQL Server\MSRS11.MSSQLSERVER\Reporting Services\ReportServer), change the “SecureConnectionLevel” element value from 0 to 3.
    Add correct value to <UrlRoot> element.
    Add the same value to the <ReportServerUrl> element as step2.
    Go to Microsoft management Console, add the certificate which you use to access the report server under “Trusted Root Certification Authorities”.
    For more information about SSL configuration and Managing Trusted Root Certificates, please refer to the following documents:

  • IPod software server could not be connected

    I receive this error when I try to update my iPod. I confirm that my internet connection is live before I do so. My link to my wireless router is broken after I get the error message. There is probably a way to reconnect it but the only way I know is to reboot. When I shutdown I get a blue screen with DRIVERIRQL_NOT_LESS_OREQUAL. It references a USB port, the one my iPod is connected to, I suppose.
    I used to be able to update my ipod on this PC and can still do so on my laptop. I set all my IE settings on this PC to be the same as my laptop.
    My windows firewall is turned off and I tried the update with my symantec internet security software turned off. Same error.
    I updated all the hardware drivers on my PC. Same error.
    I followed the instructions in Article 304468 which says to validate that the LAN auto detect is on. Same error.
    As per article 93698 I deinstalled:
    iTunes
    Quicktime
    Apple Software update
    Apple Mobile Device support
    Bonjour (although not referenced in the article I noticed that it got installed the first time I deinstalled and reinstalled iTunes)
    I killed all processes related to these before deinstalling them. Afterwards I deleted all related folders in the program directory, all temporary files and all files in trash.
    After reinstalling iTunes I got the same error.
    I use Internet Explorer as my default browser as recommended in another posting.
    I turned off the "Check for publisher's certification revocation" in the IE Advanced Security settings as recommended in another posting.
    I use IE version 7.0.5730.13 and Windows XP pro version 2002 service pack 2.
    Any suggestions would be very much appreciated.
    Thanks.

    Update Server
    Try:
    - Powering off and then back on your router.
    - iTunes for Windows: iTunes cannot contact the iPhone, iPad, or iPod software update server
    - Change the DNS to either Google's or Open DNS servers
    Public DNS — Google Developers
    OpenDNS IP Addresses
    - Try on another computer/network
    - Wait if it is an Apple problem

  • Dispatcher Running Server Not Connected

    Hi,
    I have the same problem on Windows 2003 Server EP6 WAS640 SR1 SP9
    I have the WAS640 for ABAP with the Java Add In and the Enterprise Portal installed on top.
    When I try to connect to the Portal through a browser I get the message:
    Dispatcher Running Server Not Connected
    In the JCMON I cannot start Server0 and I get the errors 1,2,3,4 and it tries to start and then goes to status STOPPED
    Does anyone know the solution ?
    My system was working, the last change I made was to authenticate users against an SAP system and then I did a reboot and now the J2EE won't start.
    Any help is much appreciated.
    Thanks,
    Tomas.

  • TS1717 Error comes up in iTunes on check for updates "The iTunes update server could not be contacted.  Please check your internet connection, or try again later."  Currently connected to the internet, on HP Laptop running latest version of Windows 7.

    Error comes up in iTunes on check for updates "The iTunes update server could not be contacted.  Please check your internet connection, or try again later."  Currently connected to the internet, on HP Laptop running latest version of Windows 7.
    I get the same problem running the diagnostics.  Says network connections are present and in the green, but unable to connect to iTunes Store.

    I downloaded the Microsoft Autoruns package and ran it.  There are no programs in the LSA Providers tab, and Apple's Bonjour is the only program in the Winsock Providers tab.  I also did the "netsh winsock reset" and rebooted.  It didn't fix the problem.  Any more ideas?

  • Clean Access Server could not establish a secure connection

    I have a OOB Real IP GW setup on v4.1.2
    I seem to have a problem with the CAS connecting to the CAM although I have added the CAS to the CAM and can manage the CAS from the CAM.
    I noticed while troubleshooting client authentication that the client was not being redirected to the logon web page and it had full access to the trusted network from the untrusted authentication vlan. I eventually figured out that if I change the CAS Filter Fallback method from Allow to ignore then it tries to authenticate the client. However the fact that the fallback is activated tells you that something is not right.
    I have 2 problems:
    A) The clients web page is redirected for authentication but it only lists the domain name in the URL and not the hostname or host IP. In the lab I do not have a DNS server and it would not help as it does not include the hostname in the URL anyway. How do I fix this or perhaps it's related to the 2nd problem.
    B) When I manually change the URL by replacing the domain name with the IP of the CAS (untrusted OOB Real IP GW) then I get the following error message when logging on:
    Network Error:
    Clean Access Server could not establish a secure connection to Clean Access Manager at mydomain.com.
    This could be due to one or more of the following reasons: 1) Clean Access Manager certificate has expired 2) Clean Access Manager certificate cannot be trusted or 3) Clean Access Manager cannot be reached.
    Please report this to your network administrator.
    I would guess the culprit is No 2 but surely the system can run on self signed certificates? I have an NTP server so time is in sync. I have even tried regenerating the cetificates on the CAM
    & CAS.
    Any ideas?

    To overcome problem B, I regenerated the SSL Certificates using the host IP address instead of the name for all the CAM & CAS appliances. This seems to have resolved this problem.
    I also SSH'd from each of the CAS's to each of the CAM's from the CLI and it then prompts to permanently store the certificates. I'm not sure it this was necessary though.

  • I am trying to update my itunes to the latest version, but it says the itunes server could not be updated and i need to connect to the internet when I amlready am connected

    I am trying to update my itunes to the latest version, but it says the itunes server could not be updated and i need to connect to the internet when I amlready am connected. How do I get the latest version of itunes so i can sync my iphone with itunes without losing all my songs?

    We were able to fix our machine!  I just could not make sense of the error message, so we were trying non-Microsoft, non-Apple solutions. 
    Our Solution:  Install MalWareBytes, and run a Quick Scan.
    Even thought both Microsoft anti-virus and Defender were running on our Windows 8 machine, MalWareBytes found about 100 problems.  As I looked over the types of problem and locations, I found several that referenced the exact directory referenced in this message.  The machine had to be restarted for MalWareBytes to complete the cleaning, but iTunes installed afterwards with no problems.
    Thank you MalWareBytes!

  • A connection to the QuickTime server could not be established. This computer may be having trouble accessing the Internet or the server may be offline

    When I select “Update existing software in QuickTime Pro I get an error message saying “A connection to the QuickTime server could not be established. This computer may be having trouble accessing the Internet or the server may be offline”
    This has persisted for several weeks. Any help will be welcomed as I do not know how to contact QuickTime support via Apple.
    I am using Windows 7 64 bit.  
    Many thanks

    I was able to download and install the latest version of iTunes  (10.6.3.25) without a hitch. After the reboot I tried again to update my exisitng Quicktime Pro software as described in my original posting and got exactly the same error message.
    If it happens that there is no software to download because I am already running the latest version, surely a message to that effect would appear and not the one saying “A connection to the QuickTime server could not be established. This computer may be having trouble accessing the Internet or the server may be offline”
    Still seeking advice if possible
    Cheers
