You run one Oracle-supplied script, and the database works through every invalid object, so users do not meet them one by one. The script is <code>utlrp.sql</code>. It lives in the <code>$ORACLE_HOME/rdbms/admin</code> directory, and the <code>?</code> in the path below is the SQL*Plus shortcut for that home.</p> <p>An object becomes invalid when something it depends on changes. A view can query a table. A PL/SQL subprogram can call other subprograms or read tables. If the referenced object changes in a way that matters, the dependent object is marked invalid. The database can repair many of these by itself when the object is used. A planned recompile moves that work to a time you choose.</p>
