Backing Up Oracle - Computing at Cornell

Appendix E. TDP for IBM ESS for Oracle databases
E.1 IBM ESS FlashCopy
In this appendix, we show an example of a backup and restore operation
using Tivoli Data Protection (TDP) for IBM Enterprise Storage Server (ESS)
for Oracle databases. We show how we set up each component and how the
actual backup and restore commands were working. For further information
and requirements, see Tivoli Data Protection for IBM ESS for Oracle
Databases, SH26-4125-00.
Our setup uses the following components:
Two RS/6000 with AIX 4.3.3.0
ESS with LIC SC01206
Oracle Version 8.1.5
TDP for Oracle 2.1.0.10
TDP for ESS for Oracle 1.1.0.0
TSM server 3.7.3
TSM client 4.1.1
In this section, we briefly describe the FlashCopy feature of the IBM ESS. For
further information, see Redbook Implementing ESS Copy Services on UNIX
and Windows NT/2000, SG24-5757-00.
FlashCopy is a feature of the ESS that allows you to establish an identical
and independent copy of a source ESS volume to a target ESS volume. The
target volumes should be assigned to another physical machine. If the target
volume is assigned to the same machine where the source volumes are, the
operating system may have problems identifying the new disk volume, as it is
an exact copy of the original disk. Things like unique disk identifiers, size of
the disk, the copied data itself will appear twice on the same machine, which
may cause problems.
See Figure 59 for an example setup.
