Integrating SAP R/3 and Data Protector
Restoring an SAP R/3 Database
Chapter 2210
Check the instructions from the database/application vendor on how to
prepare for a disaster recovery. See also the HP OpenView Storage Data
Protector Disaster Recovery Guide for instructions on how to approach
system disaster recovery using Data Protector.
This is a general procedure for recovering an application:
1. Complete the recovery of the operating system.
2. Install, configure, and initialize the database/application so that data
on the Data Protector media can be loaded back to the system.
Consult the documentation from the database/application vendor for
a detailed procedure and the steps needed to prepare the database.
3. Ensure that the database/application server has the required Data
Protector client software installed and is configured for the
database/application. Follow the procedures in this chapter and in the
troubleshooting section.
4. Start the restore. When the restore is complete, follow the
instructions from the database/application vendor for any additional
steps required to bring the database back online.
Restoring the Control File
The control file contains all the information about the database
structure. If the control file has been lost, you must restore it before
restoring any other part of the database.
Perform the following steps:
1. Restore the control file using the standard Data Protector restore
procedure.
The control files (ctrl<ORACLE_SID>.dbf) are by default restored to
the directory defined by the SAPBACKUP variable. If the variable is
not set, the control files are restored to the following directories:
• /var/opt/omni/tmp (HP-UX and Solaris systems),
• /usr/opt/omni/tmp (other UNIX systems), or
• <Oracle_home>\tmp (Windows systems).
