When exporting data from a database, you receive following error:
EXP-00056: ORACLE error 6550 encountered ORA-06550: line 1, column 41: PLS-00302: component 'SET_NO_OUTLINES' must be declared ORA-06550: line 1, column 15: PL/SQL: Statement ignored EXP-00000: Export terminated unsuccessfully
You are probably using another version of the export tool than the version of the database.
For instance, you use the Oracle 10g export tool to export a schema from an Oracle 9i database.
The export tool of Oracle contain some version specific code.
In this case, the export tool is executing a procedure at connect time (set_no_outlines) which does not exist on an Oracle 9i database.
It is good practice to keep the version of the Oracle client tools and database in sync.
This problem will disappear if you use the Oracle 9i version of the export tool.
