org.omg.CORBA.TRANSIENT: initial and forwarded IOR inaccessible vmcid: IBM minor code: E07 from stan


I'm connecting to the WebSphere instance from the stand-alone Java app which is quite trivial:

InitialContext initCtx = new InitialContext();

That code was working perfectly in WebSphere 7, but after updating to WebSphere 8.5 I got the following exception:

Caused by: org.omg.CORBA.TRANSIENT: initial and forwarded IOR inaccessible vmcid: IBM minor code: E07 completed: No at com.ibm.rmi.corba.ClientDelegate.createRequest(ClientDelegate.java:1276) at com.ibm.CORBA.iiop.ClientDelegate.createRequest(ClientDelegate.java:1457) at com.ibm.rmi.corba.ClientDelegate.createRequest(ClientDelegate.java:1164) at com.ibm.CORBA.iiop.ClientDelegate.createRequest(ClientDelegate.java:1423) at com.ibm.rmi.corba.ClientDelegate.request(ClientDelegate.java:1886) at com.ibm.CORBA.iiop.ClientDelegate.request(ClientDelegate.java:1379) at org.omg.CORBA.portable.ObjectImpl._request(ObjectImpl.java:458) at com.ibm.WsnBootstrap._WsnNameServiceStub.getProperties(_WsnNameServiceStub.java:38) at com.ibm.ws.naming.util.WsnInitCtxFactory.mergeWsnNSProperties(WsnInitCtxFactory.java:1441) ... 43 more

After research, I've fout out that <a href="http://www-01.ibm.com/support/docview.wss?uid=swg21614221" rel="nofollow">IBM support page</a>, which said to go to CSIv2 inbound and outbound settings (by me, Admin Console->Security->GlobalSecurity->RMI/IIOP security) and set the transport to SSL-Supported.

However, it didn't change anything. I've tried to change the 'Cleint certificate authentication' to Never, and Transport to TCP/IP for both CSIv2 inbound and outbound, but still without success. The error persisted until I've turned off 'Enable administrative security', which is not an option, because I need to enable 'Application Security' (the application logic depends of that).

How can I make my code working again? Everything was OK on WebSphere 7.


The error description

<blockquote> <blockquote>

org.omg.CORBA.TRANSIENT: initial and forwarded IOR inaccessible vmcid: IBM minor code: E07

</blockquote> </blockquote>

is very vague and happens under many, not directly connected circumstances.

In my case it had nothing to do with RMI/IIOP security settings, but it was a <strong>classpath problem</strong>. I was still using old version of com.ibm.ws.webservices.thinclient.

Switching to thinclient 8.5.0, as well as setting the launch JRE to standard (Oracle) JVM has fixed the problem.


My research on this issue may prove useful to others;

WebSphere 8 changed the default setting of RMI/IIOP SSL security from 'supported' to 'required'. If you want a secure connection you'll need to get the certs from the server and set Java system properties to files that specify the location of the certs;

<blockquote> com.ibm.CORBA.ConfigURL=file:/opt/IBM/JazzSM/profile/properties/sas.client.props com.ibm.SSL.ConfigURL=file:/opt/IBM/JazzSM/profile/properties/ssl.client.props </blockquote>

If this doesn't work, you'll need to start debugging by setting the following System properties;

<blockquote> com.ibm.CORBA.Debug=true com.ibm.CORBA.CommTrace=true com.ibm.CORBA.Debug.Output=/tmp/corba.log </blockquote>

By studying this log and orb trace logs in the working directory, I found that the client failed to establish an ephemeral TCP connection to the server at "port=0". No mention of SSL in the logs! I wrote a small app to test my code running as a java console app and found that the SSL connection was successful and it worked fine. By diff'ing the logs, I found that only in the good case, the JVM was finding a local file 'orb.properties'. I then found that in my problem case, my test app was using a different JVM and my real app was using a JVM that had no 'orb.properties'. I could resolve the problem in a number of ways .. e.g. by including an orb.properties in my application and injecting the contents as System properties.


In my case switching CSIV inbound to SSL-Supported from SSL-required <strong>and</strong> restarting the server helped.
