Debugging / Tracing DBCA

1. Do a copy of the original dbca file in $ORACLE_HOME/bin. For example:

cp $ORACLE_HOME/bin/dbca $ORACLE_HOME/bin/dbca.ori

2. vi the dbca file in the $ORACLE_HOME/bin directory.

3. At the end of the file, look for the following line:

# Run DBCA

$JRE_DIR/bin/jre -DORACLE_HOME=$OH -DJDBC_PROTOCOL=thin -mx64m -classpath $CLASSPATH oracle.sysman.assistants.dbca.Dbca $ARGUMENTS

4. Add the following just before the -classpath in the '$JRE_DIR' line:

-DTRACING.ENABLED=true -DTRACING.LEVEL=2

5. At the end of the dbca file, the string should now look like this:

# Run DBCA

$JRE_DIR/bin/jre -DORACLE_HOME=$OH -DJDBC_PROTOCOL=thin -mx64m -DTRACING.ENABLED=true -DTRACING.LEVEL=2 -classpath $CLASSPATH oracle.sysman.assistants.dbca.Dbca $ARGUMENTS

6. To trace, run:

[tstdb01]/u01/tstdb1/db1> dbca > dbca.out &

The output will be written to the dbca.out file.
