These messages are warnings. SQLPlus should be accessible, although this may be seen as a symptom of not following our instructions and/or database template during installation.
These associated error messages are warning you that the PRODUCT_USER_PROFILE table has not been built in the SYSTEM account.
Running the PUPBLD.SQL script is optional, but is needed to get rid of the SQL*Plus warning messages that are associated to it.
To create this table, a Database Administrator ( DBA ) must run the PUPBLD.SQL script located in the Oracle home directory. This script must be run as user SYSTEM.
If the PRODUCT_USER_PROFILE table is created incorrectly, all users other than SYSTEM will see a warning when connecting to Oracle from SQL*Plus that the PRODUCT_USER_PROFILE information is not loaded.
