ORA-00600 [KGHALO4]

We got an ORA-00600 [KGHALO4] error today every time we tried to create the ASM instance with DBCA. We found that this is a bug in 10.2.0.1. See MetaLink Note: 340976.1.

Solutions:

Apply the one-off patch for bug 4414666 or set the _enable_NUMA_optimization=FALSE parameter in the init.ora as a workaround. For an ASM instance, two parameters are needed:
_enable_NUMA_optimization = FALSE _disable_instance_params_check = TRUE. Another solution is to apply the 10.2.0.2 patchset which fixes this problem.

Because this bug happens whenever you are trying to create the ASM Instance, it would be advisable to just apply the one-off patch for the bug and then install the 10.2.0.2 patchset as normal once everything is created and working.
