Did you upgrade your database from another version? If so, you need to re-run the appropriate upgrade script (for example, u0801060.sql if upgrading from 8.1.6) and make sure to set _system_trig_enabled=false before running the script.
Hope this help.
I ran the rapid install in oracle applications 11.5.5 . I have to manually create the 8.1.7 database, which I did. Now i had to run those 3 cat... scripts.
after that i had to import 7.3.4 database into this 8.1.7
