A while back I had the problem that my CRS information was lost.
Now I had found that when I did a crs_start of the component I received the following error:
CRS-0254 authorization failure
Some investigation showed that the problem was related to the fact that the component was not owned by the oracle user.
Using crs_getperm ora.ORCL.db showed the problem.
This can be solved by doing the following:
crs_setperm ora.ORCL.db -o oracle
crs_setperm ora.ORCL.db -g dba
Now it works again.
