Figure 1-7. Dynamic coupling is introduced through a reference to an interface of a class. Now class A holds a reference to type B, but the executable code for Method1 is in class C, derived from B. If you assume that A.myReference is initialized using a reference received from another object, A will have dynamic, but not static, coupling to C. A will think myReference points to a B object, while it actually points to a C object. Class A doesn t know about the existence of C, and calls C.Method1 through B s interface. Class A is statically coupled to B because the compiler needs to know the layout of type B in order for A to call B.Method1. At run time, C needs to be present, because A calls C s implementation of B.Method1.

You can issue the CATALOG command to catalog older backups in the recovery catalog. By issuing the CATALOG command, you can catalog older backups that have aged out of the control file, thus enabling RMAN to use those backups during a file restore operation. Here s an example that shows how to use the CATALOG command: RMAN> CATALOG DATAFILECOPY '/u01/old_backups/users01.dbf'; You can execute the CATALOG START WITH command to catalog multiple files in a directory, as shown here: RMAN> CATALOG START WITH '/u01/old_backups/'; RMAN waits for your confirmation after listing each file, before adding the file to the recovery catalog.

If your RMAN client is from the Oracle 11.1 release, but the recovery catalog schema is from an older version, you must upgrade the recovery catalog. You can determine the schema version of the recovery catalog by executing the following query: SQL> SELECT * FROM rcver; VERSION --------10.02.00 If the output of this query shows multiple rows, the highest version number is the catalog schema version. In our example, there s only one version number, 10.2.0, meaning that the catalog version is 10.2.0. In order to upgrade the recovery catalog, follow these steps: 1. If the recovery catalog owner that you created is from a release before 10.1, execute the following GRANT command (assuming that rman is the catalog owner): SQL> GRANT CREATE TYPE TO rman; 2. Start RMAN and connect to the recovery catalog database. RMAN> connect catalog rman/rman; 3. Execute the UPGRADE CATALOG command. RMAN> UPGRADE CATALOG; 4. Confirm the command by rerunning it. RMAN> UPGRADE CATALOG; You can now use the recovery catalog with the RMAN client from the Oracle Database 11g release.

You may have multiple recovery catalogs, each taking care of databases from different versions of the Oracle database. You can consolidate those recovery catalogs into one catalog, by using the IMPORT CATALOG command. By default, the command imports metadata for all databases registered in the source recovery catalog to the destination recovery catalog. You can, however, specify the databases you want to import into the destination catalog. Also by default, RMAN unregisters an imported database from the source recovery catalog, but you can retain the imported databases in the source catalog by adding the NO UNREGISTER clause to the IMPORT CATALOG command. Your target databases, recovery catalog databases, and the recovery catalog schema can be from different database versions. However, Oracle recommends that you consolidate all your recovery catalogs into a single catalog at the most recent version of the recovery catalog schema. The IMPORT CATALOG command helps you do this. In the following example, I use the IMPORT CATALOG command to merge two recovery catalogs, one from the 10.2 release and the other from 11g, into a single 11g release catalog schema. Here are the steps: 1. Connect to the destination recovery catalog. $ rman RMAN> connect catalog rman/rman@rman11

Dynamic coupling is not commutative. To understand why, let class A contain a reference to class B. Class A uses the reference to call methods of B. Class A requires class B to be present at run time; otherwise, the executable code for the methods that A calls won t be present and the calls will fail. Class B doesn t require class A at run time, because B doesn t even know that A exists. Therefore, class B is not dynamically coupled to class A.
