BBED

BBED is an Oracle internal utility to do BLOCKEDIT. It is extensively discussed at http://www.orafaq.com/papers/dissassembling_the_data_block.pdf BBED doesn't work on ASM by default. A work-around has been studied by http://oracleprof.blogspot.com/2009/06/asm-and-bbed.html

An example to get started can be found here below.
Note that bbed does not build out of the box on 11g and 12c, as there are a few files missing in the Oracle binaries distribution to properly build bbed. There is a simple workaround, that consists on copying the relevant files from 10g binaries before running make. More details at this blog entry by Laurent Leturgez http://laurent-leturgez.com/2011/06/29/bbed-in-oracle-11g/
