In 8.1.7 is pupbld.sql loacted at ORACLE_HOME/dbs/? I just created a DB manually and I'm trying to run that script as system but anytime I try it does not work.
e.g.
SQL> @$ORACLE_HOME/dbs/pupbld.sql
SP2-0310: unable to open file "/u01/app/oracle/product/8.1.7/dbs/pupbld.sql"
SQL>

When I try to connect as an ordinary user, I get the message so I need to run that script:

SQL> connect michael_pak
Enter password:
Error accessing PRODUCT_USER_PROFILE
Warning: Product user profile information not loaded!
You may need to run PUPBLD.SQL as SYSTEM
