Pinned topic Problems with authentication in the Information Server

‏2008-07-21T23:54:50Z |
Hi,

Can you give me a solution for the following problem when I connect to the datastage 8.01.

  • Client on Windows XP Professional(SP2).
  • The information server is installed in linux Red Hat.

The error message is below:

A communication failure occurred while attempting to obtain an initial context with the provider URL: "iiop://mydatastageserver.com.br:2809". Make sure that any bootstrap address information in the URL is correct and that the target name server is running. A bootstrap address with no port specification defaults to port 2809. Possible causes other than an incorrect bootstrap address or unavailable name server include the network environment and workstation network configuration.

  • I added the entrances in host. (client). C:\WINDOWS\system32\drivers\etc\host
127.0.0.1 localhost
192.168.100.186 mydatastageserver.com.br

  • ping mydatastageserver - ok

  • telnet mydatastageserver 2809 - ok

  • Some workstations this software executes normally. The problem occurs when I make a new installation client.

Thanks for help.

MarcosBarcellos.

    This seesm to be a consistant issue. I've having the same problem... Windows DS client -> Redhat DS Server.
    I found this link which suggests its a problem to do with hostnames.

    http://www.ibm.com/developerworks/forums/thread.jspa?messageID=14226323&tstart=0

    But in my case the hosts file contains the IP addres and name correctly set up.
    And I found this support description which suggests it a firewall issue.

    http://www-01.ibm.com/support/docview.wss?rs=14&context=SSZJPZ&dc=DB560&dc=DB520&uid=swg21381848&loc=en_US&cs=UTF-8&lang=en&rss=ct14db2

    However, in my case, all ports are open.

    So I would suggest there is a bigger issue here that what i've described above.

    If anyone has sorted this problem in the past then your insight would be very appreciated.

    thxs, Bob

    I also came across this link to IBM support

    http://www-01.ibm.com/support/docview.wss?uid=swg21319111

    Which suggests that the client connectivity problem could be due to the client having multiple IP addresses or the client running on a NAT router.
    Mine has both, multiple ip addresses and a running on a nAT router. The latter is a showstopper apparently. Not sure if this is a DataStage issue or a general JNDI issue at the moment. But I'll try connecting to the server without the NAT router in the loop as see how that goes.
