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, e.g. 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
