When you install Oracle 11g for use with Symantec Data Loss Prevention (DLP), you see the following error:

Copy files.... In progress
extracting '/opt/oracle/product/11.2.0/db_1/oc4j/j2ee/oc4j_applications/applications/em.ear'
file not found /opt/oracle/product/11.2.0/dbhome_1/oc4j/j2ee/oc4j_applications/applications/em.ear

The Oracle 11g installation is distributed in two separate files.

The error occurs because the file contents were not combined into a single folder before you started the installation. Therefore, the second archive cannot be found.

When you extract the contents of both zip files, merge all files into a single folder, and then start the Oracle installation again.
