ORA-00600: internal error code, arguments: [SKGMFAIL]
Date: Fri, 20 Apr 2012 10:12:46 -0700 (PDT)
I have found a lot of information on the web about ORA-00600 internal errors but very little specific to SKGMFAIL.
Oracle support responded as follows:
- symptom: Starting database fails
- symptom: ORA-00600: internal error code, arguments: [Skgmfail],, 
- cause: Unix kernel parameter SHM_MAX set too low
Check and set Unix kernel parmeters as below:
SHM_MAX = 4278190080 (4GB less 16MB) <------- this may be modify according to Doc 169706.1 as , this doc is too old.
SHM_MNI = 256 SHM_SEG = 128 SHM_MIN = 1024
In my case, these memory parameters were set correctly.
My LINUX administrator used a tool called md5sum and found that my
spfile was corrupt.
When the spfile was replaced from a backup, my database started properly.
Since SKGMFAIL. seems to be a rather obscure error I though this post might be useful to others.
