Linking Oracle BBED in 11g

Warning:

I use the Oracle Block Browser and Edit tool (bbed) for studying the internal structure of database blocks. Be very careful using the tool, you can destroy blocks using this tool so make sure you know what you are doing.

There is a nice document (PDF) about the BBED tool, titled Disassembling the Oracle Data Block which can be found here: http://orafaq.com/papers/dissassembling_the_data_block.pdf

Copy the following files from an 10g Oracle Home to 11g Oracle Home:

  • $ORACLE_HOME/rdbms/lib/ssbbded.o
  • $ORACLE_HOME/rdbms/lib/sbbdpt.o
  • $ORACLE_HOME/rdbms/mesg/bbedus.msb
  • $ORACLE_HOME/rdbms/mesg/bbedus.msg

Important: make sure you copy these files from an Oracle Home installed on the same server architecture!

Issue the following command (with the 11g Oracle home environment variables set):

make -f $ORACLE_HOME/rdbms/lib/ins_rdbms.mk BBED=$ORACLE_HOME/bin/bbed $ORACLE_HOME/bin/bbed

Output:
