Error accessing PRODUCT_USER_PROFILE...

I first log in as internal.

After the db is created and up, I run the catalog.sql and catproc.sql comes w/ Oracle to create the dynamics views etc.

After that, I create a user a/c, e.g., myaccount, identified by password. Granting myaccount w/ create session, create table privileges, & dba role.

Successful to log in as myaccount. However, as shown in the sample below, it mentions:
"Error accessing PRODUCT_USER_PROFILE..."

What does it mean? What implications and what are the steps I should do?

thanks,
jackling.

Below is a sample:

$sqlplus myaccount/password
