Oracle Database Express Edition (XE)

I wish to install Oracle XE silently. Initially I'm making sure this will work from the command line before including in an automated install.

I'm following the steps here http://download.oracle.com/docs/cd/B25329_01/doc/install.102/b25144/toc.htm#CIHHJEHF

The first step of Installing with the rpm works fine rpm -ivh /opt/mydirectory/oracle-xe-univ-10.2.0.1-1.0.i386.rpm > /opt/Mincom/XEsilentinstall.log

The problem is configuring the database using a response file fails. I can configure the database manually without any problems.

/etc/init.d/oracle-xe configure < /opt/mydirectory/tools/OracleXE-SilentInstallLinux.iss >> /opt/mydirectory/XEsilentinstall.log

The response file OracleXE-SilentInstallLinux.iss contains the following 4 rows - exactly as per the instructions in the url above

9080
1521
systempwd
systempwd
y

The output that is written to the log file is

You must run '/etc/init.d/oracle-xe configure' as the root user to
configure the database.

Ctrl-C will abort.

different passwords for each database account. This can be done after
initial configuration:

The Oracle doco I have read states:
"Oracle Universal Installer treats wrong context, format, or type values within a response file as if no value were specified. In addition, variables which are outside of any section are ignored."

Can anyone provide a better response file please?
