9.7.3.1 Coexistence of backup-archive client and TDP for Oracle When using the incremental command of the backup-archive client, you should exclude the database objects that are backed up using TDP for Oracle. While the database is running, you will not get a consistent backup using the backup-archive client. In our environment, all the files that were backed up using TDP for Oracle where in the c:\oracle\oradata directory. To prevent them from being backed during a full incremental backup, we added an exclude.dir statement to the dsm.opt file: exclude.dir c:\oracle\oradata To prevent those files from being backed up with a selective command, we also added this statement: exclude c:\oracle\oradata\...\* You may wish to use additional exclude statements to prevent other files from being backed up during your incremental backups. However, you should consider using an include statement to back up Oracle.ORA files (tnsnames.ora, init.ora, etc..) These files would make a disaster recovery restore much easier: include c:\oracle\admin\...\*.ora include c:\oracle\ora81\...\*.ora After making these changes, our resulting dsm.opt file looked like this: COMMMETHOD TCPIP TCPSERVERADDRESS 193.1.1.11 TCPPORT 1500 NODENAME JAMAICA PASSWORDACCESS GENERATE exclude.dir c:\oracle\oradata include c:\oracle\admin\...\*.ora include c:\oracle\ora81\...\*.ora exclude c:\oracle\oradata\...\* With these include/exclude statements, the Oracle database files will not be backed up in the TSM backup-archive client incremental. 152 Backing Up Oracle using Tivoli Storage Management
Chapter 10. Oracle backup considerations on Windows 2000 RMAN is the backup and recovery tool provided by Oracle for Oracle8 Server databases and is packaged with the Oracle8 Server product. RMAN manages the process of backing up, restoring, and recovering Oracle8 target database instances. RMAN can automatically back up, restore, and recover the following database objects: Database Tablespaces Data files Control files Archived redo logs In addition to backup and restore operations, RMAN can: Generate log records of all backup and recovery operations Run backup and restore operations in parallel to improve performance Find database objects that require a backup, on the basis of user-defined values RMAN provides the interface to the Oracle8 database and the functions for backup, restore, and recovery. It does not provide any storage management capabilities and must be integrated with other storage management products such as TSM to provide a complete enterprise wide storage management solution. 10.1 RMAN: Oracle Recovery Manager This section presents an overview of the architecture and the components involved in backing up Oracle8 databases with RMAN and TDP for Oracle. It is an introduction to RMAN and in particular how it integrates with TSM. It is not an authoritative guide to RMAN or Oracle8 backup and recovery. This chapter should be read in conjunction with the Oracle8 Server Backup and Recovery Guide. 10.1.1 RMAN system components RMAN consists of several components that interact during the backup and recovery process.
