instance startup failed in linux...
My database was starting automatically with linux startup... but I did some changes in NETWORK CONFIGURATION changed HOSTNAME: TEST from HOSTNAME: local.localdomain 
now again I reset its previous value to HOSTNAME: local.localdomain
when I log off and at login I get below message:
Could not look up internet address for localhost.localdomain. This will prevent GNOME from operating correctly.
It may be possible to correct the problem by adding localhost.localdoman to the file /etc/host
when I am login I the Oracle instance its not started automatically...
when I issue startup..i get below error:
ora-00600: internal error code, arguments: [keltnfy-ldmInit], [46], [1], [], [], [], [], []
