The Oracle RMAN can perform: Full or tablespace backup of a database while it is online or offline Full database restore while it is online or offline Tablespace restore while database is offline Backups of archive log files Block level incremental backup RMAN API V2 Support Oracle 8.1 has introduced a new RMAN Media Management API V2, which is supported by Tivoli Data Protection for Oracle, V2.2. RMAN Duplex Copy Feature Support Oracle8i RMAN V2.0 has new functionality. One such feature is Duplex Backup Copy, which permits the customer to make multiple copies of a backup on different media. This feature can be enabled by defining multiple management classes in the Tivoli Data Protection for Oracle, V2.2 option file. Multi-Buffering of RMAN Data Transfers During a backup, the network is often the bottleneck. Tivoli Data Protection for Oracle, V2.2 introduces a new option to turn on multi-buffering. If this option is used, the data buffers sent from RMAN are saved in Tivoli Data Protection for Oracle internal buffers, instead of being sent directly to the Tivoli Storage Manager server across the network. Tivoli Data Protection for Oracle then starts a new thread which will pick up these internal buffers and send them to the Tivoli Storage Manager server. In this way, RMAN does not need to wait for each actual data transfer to be completed via the network before reading more data. In many cases, this buffering can increase backup performance. New Synchronization Utility The synchronization utility in Tivoli Data Protection for Oracle, V2.2 will make more space available on the Tivoli Storage Manager server by identifying and removing backups that have been deleted from the Oracle catalog. When deleting backup sets using Oracle8 RMAN, in earlier RMAN versions, RMAN deletes the recovery catalog entries before receiving confirmation from the Tivoli Storage Manager server. In the case where deletion from the server was not successful, these backup sets are no longer identifiable through the recovery catalog. Tivoli Data Protection for Oracle includes a new utility that reconciles these discrepancies by displaying and, optionally, deleting files that exist on the Tivoli Storage Manager server but are no longer in the recovery catalog, allowing the user to reclaim lost space on the Tivoli Storage Manager server. Additional Usability Enhancements The new configuration utility makes setup of Tivoli Data Protection for Oracle easier than ever before. A new options file centralizes information for setup. Environment variables are no longer needed. This simplifies the establishment of multiple sessions, and significantly reduces the opportunity for human error associated with entering environmental variables for individual sessions. In addition, the new tdpoconf utility will be a great help in solving problems that can be associated with setup. For example, if the password file is not initialized properly, tdpoconf will report this error immediately, and so remove the complications that can result if this error goes undetected. New 64-bit Support for Sun Solaris 8 and HP-UX 11 Tivoli Data Protection for Oracle continues our customer commitment by adding 64-bit support for Solaris 8 and HP-UX 11 in this release. Effective Use of the Power of Tivoli Storage Manager The Tivoli Storage Manager server's capabilities include: Access to a storage hierarchy Migration (server Hierarchical Storage Management or HSM) through the storage hierarchy Management of tape media space Disaster recovery support including off-site management of tapes During operation of Tivoli Data Protection for Oracle, the Tivoli Storage Manager server manages the location of every object and manages the devices. If additional space savings are desired in cases of very high redo log file activity, customers can take advantage of the Hierarchical Storage Management functions on the Tivoli Storage Manager AIX or Solaris clients by ordering the Space Management product, 5698-SPM. Refer to the Reference Information section to obtain ordering information for Space Management. LAN-free Support The Tivoli Storage Manager Managed System for SAN feature provides the capability for LAN-free data transfer for Oracle8 and Oracle8i database data on Windows NT and Windows™ 2000. LAN-free data transfer exploits the SAN path by enabling Tivoli Data Protection for Oracle to backup and restore data from a SAN-attached tape library that can be shared by Windows NT and Windows 2000 Tivoli Storage Manager servers. Refer to the Reference Information section to obtain ordering information for the Tivoli Storage Manager Managed System for SAN feature for the Windows NT and Windows 2000 platforms. _______________________________________________________ Send a cool gift with your E-Card http://www.bluemountain.com/giftcenter/
