4、 a media manager with Oracle. A media manager is not an Oracle product and must be obtained from a third-party vendor. If you choose to use RMAN with a media manager, then you must obtain all product-specific information from the vendor.This section describes the generic steps for configuring RMAN f

5、or use with a media manager. The actual steps depend on the media management product that you install and the platform on which you are running Oracle.Read the following sections in order when configuring the media manager:1. Prerequisites for Using a Media Manager with RMAN 2. How Oracle Interacts

7、ons for RMANPrerequisites for Using a Media Manager with RMANBefore you can begin using RMAN with a media manager, you must install it and make sure that RMAN can communicate with it. Instructions for this procedure should be available in the media manager vendors software documentation.Depending on

8、 the product that you are installing, the following basic steps apply:1. Install and configure the media management software on the target host or production network. No RMAN integration is required at this stage. 2. Ensure that you can make non-RMAN backups of operating system files on the target d

9、atabase host. This step makes later troubleshooting much easier. Refer to your media management documentation to learn how to back up files to the media manager. 3. Obtain and install the third-party media management module for integration with the Oracle server. This module must contain the library

10、 that Oracle loads when accessing the media manager. If you have not performed the preceding steps, then do not proceed with the media management configuration.How Oracle Interacts with the Media ManagerTo make backups to a media manager, RMAN must communicate with a media management library. The pr

11、ocedure for using RMAN with a media manager in Oracle9i has not changed from previous releases.The loading of a media manager library is operating system specific. When you RMAN allocates channels, it uses the following algorithm when deciding which library to load:1. Attempts to load the library in

12、dicated by the SBT_LIBRARY parameter in the ALLOCATE CHANNEL or CONFIGURE CHANNEL command. If the SBT_LIBRARY parameter is not specified, then Oracle proceeds to the next step. 2. Attempts to load the default media management library. The filename of the default library is operating system specific.

13、 On UNIX, the library filename is $ORACLE_HOME/lib/libobk.so, with the extension name varying according to platform: .so, .sl, .a, and so forth. On Windows NT the library is named %ORACLE_HOME%binorasbt.dll. Note:The default media management library file is not part of the standard Oracle installati

14、on as in previous releases, so you can only create it by installing third-party media management software.3. If Oracle is unable to locate the default library in the previous step, then RMAN issues an ORA-27211 error and exits. Whenever channel allocation fails, Oracle writes a trace file to the USE

15、R_DUMP_DEST directory. The following shows sample output:SKGFQ OSD: Error in function sbtinit on line 2278 Look for SBT Trace messages in file /oracle/rdbms/log/sbtio.logSBT Initialize failed for /oracle/lib/libobk.soIntegrating RMAN with the Media Manager: Basic StepsAfter you install the media management software, the media management library should already be integrated with the Oracle server. You should not have to perform further integration. However, you may choose to follow the procedure in t
