Answer 1

The error message says that SCHEMA_RESTORE.RESTORE cannot be found. There are several possible causes:

• The package (and procedure) are in a different schema, eg you compiled it as user A but are trying to call them as user B.
• You don't have the access right to execute procedures from the package. Thus it becomes invisible.
• You have defined the procedure in the package body, but haven't declared it in the package header.

A further problem I can see are the parentheses. If you call a procedure without arguments, the prentheses shoul be omitted:

{ call SCHEMA_RESTORE.restore }

Answer 2

It comes when you make a procedure in one user and connect the db in another. To solve this issue try this

GRANT EXECUTE ON procedureName TO username

Otherwise connect with correct username which you using

Answer 3

Did the procedure compile successfully ? Also check if you can see it via some editor (PL/SQL dev ?) under the schema

or you may use this to see if it is there -

SELECT * FROM DBA_OBJECTS WHERE object_name = '%your proc name%';
