Description of Doc ID: Note: 5486074.8 in meatlink of Oracle: this error message is displayed when Oracle cannot determine the host name or network address.
Oracle fixed this bug in 10.2.0.4 and 11.1.0.6. On metalink of Oracle, this error may occur before 10.2.0.4.
However, the test shows that Oracle9i does not cause errors due to the modification of the hostname.
Fault analysis:
When the database cannot group the host name or NIC address, it should be because I manually modified the HOSTNAME and the virtual machine's ethernet card did not obtain the IP address due to the local network change, triggering the database version BUG.
 
Solution:

(1) first restart the network service, so that the network card is bound to the IP address, startup can start the database, but the alert Log is still intermittent error ORA-00600 (every several seconds) as follows:
(2) manually modify the HOSTS file so that the host name that I manually modified using HOSTNAME corresponds to the IP Address: view the alert Log to solve the problem.

Summary:

Oracle fixed this bug in 10.2.0.4 and 11.1.0.6. On metalink of Oracle, this error may occur before 10.2.0.4.
