In my previous post, I had demonstrated how you can view the "count of records" in different sections of the controlfile. However, you cannot actually view the data in those records.
You can, however, do a Physical Dump of the controlfile :
QL> select name, block_size*file_size_blks/1024
2 from v$controlfile;

The "alter session set events 'immediate trace name controlf level 10'" command does a Physical Dump of the trace file.
I can't reproduce the whole file here, but am presenting the interesting bits.
