ORA-00017: session requested to set trace event

ORA-00017: session requested to set trace event

Cause: The current session was requested to set a trace event by another session.

Action: This is used internally; no action is required.

Explanation:

The following users or roles are not in present in the database in which you are importing the data. There are several ways to handle the problem.

If the users or roles needed to exist in this database and the export was a user level export (import command had the parameter owner=) you need to create the users or roles before importing. First determine in they are are users or roles by query dba_users and dba_roles in the database that the export was created from.

If the users or roles are not needed you can set the parameter grants=n in the import statement to skip the grants.

Finally if the import was created with full=y and the database you are importing into is a fresh database (no users other then Oracle users) you can use full=y on the import command to do a full import that should include the meta data to create the users and roles.
