Trace dbca - 9i tested
Please see note 188134.1

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

2. 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

3. Add the following just before the -classpath in the '$JRE_DIR' line:
-DTRACING.ENABLED=true -DTRACING.LEVEL=2

4. 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
The -DTRACING.LEVEL was missing a space after the 2 so that it looks
like 2-classpath.

5. To trace run:
[opcbsol1]/u01/home/usupport> dbca > dbca.out &
The output will be written to the dbca.out file.
