Info

The following is a description of our test database environment: The operating system DBA user is oracle8 in the production and backup machine. The operating system group name is dba in the production and backup machine. The database name is tokyo and only exists in the production machine. The datafiles, redo logs, and control files are in an ESS volume. Note that the redo logs and control files need not be on the same volume. The archive logs are in a local directory. The catalog database (RMAN) exists in the production machine. The name was specified in the listener.ora file. On the production machine, there is a tnsnames entry for the tokyo database, and the catalog database. In the backup machine, only the catalog database has an entry in the tnsnames.ora. There is no entry for the tokyo database. The ORACLE_HOME and ORACLE_BASE is /orc8/app/oracle/product/815 Our dsm.opt file in /usr/tivoli/tsm/client/api/bin in the production machine (auckland) and in the backup machine (swiss) looks like the one below. Note that the dsm.opt file need not be in this directory, but it must be in the same directory on both machines. servername swiss2 The stanza for swiss2 in the dsm.sys file in /usr/tivoli/tsm/client/api/bin in the production machine (auckland) looks like this: servername swiss2 tcps swiss.ibm.com tcpp 1500 passwordaccess prompt 232 Backing Up Oracle using Tivoli Storage Management
The stanza for swiss2 in the dsm.sys file in /usr/tivoli/tsm/client/api/bin in the backup machine (swiss) looks like this: servername swiss2 commmethod tcpip tcps 9.11.111.11 tcpp 1500 passwordaccess prompt shmport 1510 The tcpip address 9.11.111.11 points to swiss.ibm.com. The nodename used to back up the production database tokyo to TSM is auckland. With this configuration, we are able to backup our tokyo database to RMAN in the production environment to test that TDP for Oracle works. E.3.1.3 TDP for ESS setup For the installation, hardware, software, and environment requirements, please see the Tivoli Data Protection for IBM ESS for Oracle Databases Installation and User’s Guide, SH26-4125-00. By default, TDP for ESS uses directory /usr/tivoli/tsm/client/ba/bin. The root user will be the one performing the TDP for ESS backup and must have the following environment variables defined: DSM_CONFIG=/usr/tivoli/tsm/client/ba/bin/dsm.opt DSM_DIR=/usr/tivoli/tsm/client/ba/bin Our dsm.opt file in /usr/tivoli/tsm/client/ba/bin on the production machine (auckland) and on the backup machine (swiss) look like this: servername swiss tracefile /tmp/tokyo.trc traceflags api api_detail appl The tracefile and traceflags parameters are optional, but recommended initially during the testing of TDP for ESS. It was very valuable to us because it helped us identify any errors during a backup. Appendix E. TDP for IBM ESS for Oracle databases 233
