Uwe, Same problem here. We filed a tar with MOS and got back that it is a bug in the Oracle kernel & should be fixed in 11gR2.

The servers are configured to support host names up to 64 characters and some of them already exceed the former 8 character limit. After starting up an Oracle 10gR2 instance, I found in the logs and traces that the host name was truncated to 8 characters. The same can be observed in v$instance or sys_context('userenv','host'). So far I found only one document describing this on MOS but no further pointers to potential problems or bugs. https://supporthtml.oracle.com/ep/faces/secure/km/DocumentDisplay.jspx?id=957443.1 Do you have any experiences with this? Would you recommend to switch back the hostnames to 8 characters? Regards, Uwe -- http://oraculix.wordpress.com -- //www.freelists.org/webpage/oracle-l -- //www.freelists.org/webpage/oracle-l
