Tracing the Database Configuration Assistant (DBCA) [ID 188134.1]

Purpose

The purpose of this document is to assist in debugging Database Configuration Assistant problems and enable DBCA trace.

Scope

This document is for DBAs and support analysts to troubleshoot DBCA issues.

Details

To provide verbose output for DBCA, tracing can be enabled to provide additional 
output. To turn on tracing from 9i to 10g:

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

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

6. To trace run:

[opcbsol1]/u01/home/usupport> dbca > dbca.out &

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


In 10.2 you can add the -DDEBUG flag so that you get the debug information 
given to you interactively 

"C:\oracle\product\10.2.0\racdb\jdk\jre\BIN\JAVA" -DDEBUG -DORACLE_HOME="%OH%" -
DJDBC_PROTOCOL=thin -mx128m oracle.sysman.assistants.dbca.Dbca %* 


BUT in 10.2 you should already have the trace information written automatically 
to the following location 

$ORACLE_HOME/cfgtoollogs/dbca/trace.log

In 11g, the location of trace.log has changed to:

$ORACLE_BASE/cfgtoollogs/dbca//trace.log
