ORA-21561: OID generation failed solution

[Oracle @ adg ~] $ Sqlplus scott/tiger @ rac11gSQL * Plus: Release 11.2.0.3.0 Production on Fri Jul 19 04:16:59 2013 Copyright (c) 1982,201 1, Oracle. All rights reserved. ERROR: ORA-21561: OID generation failed

 

I have been studying this issue for a long time when I log on with sqlplus. The reason is that the machine name does not match in/etc/hosts. Here, hosts comes in through scp of another machine, after adding a line of adg resolution, you can modify the machine name in/etc/sysconfig/network. In addition, related entries are also added to the hosts and cannot be entered. Then the host name should be used to declare the host name after modification.
