Preparing Oracle in an SAP environment

Before you install IBM® Storage Protect Snapshot, verify the configuration for Oracle in an SAP environment.

IBM Storage Protect Snapshot requires that all Oracle table space data files, online redo logs, and control files are on file systems that are supported by IBM Storage Protect Snapshot.

The data that is under the sapdata, origlog and mirrlog directories must be on separate volume groups. If other data is stored within those volume groups, it is processed by IBM Storage Protect Snapshot and included in the IBM Storage Protect Snapshot backup image. This data is overwritten during a restore operation. As a result, do not store other objects such as database instance binary files and offline redo logs on the volume groups that you want to back up. SAP BR*Tools requires a list of files and directories that can be backed up. If IBM Storage Protect Snapshot detects such data in one of the volumes to be backed up, the backup operation can fail.

IBM Storage Protect Snapshot processes table spaces at the volume level. The required volume group lay out for Oracle in an SAP environment is detailed in the Volume group layout requirements section of the Pre-installation Checklist.

The hardware and software requirements for IBM Storage Protect Snapshot for UNIX™ and Linux™ are published in the following technote: http://www.ibm.com/support/docview.wss?uid=swg21427692. Follow the link to the requirements technote for your specific release or update level. From there you will find the Pre-installation Checklist and the Installation Planning Worksheet for the most recent version of the product.

IBM Storage Protect Snapshot does not support a volume and storage layout where the database is spread across multiple storage devices. In an AIX® logical volume manager mirroring environment, each mirror must be located within a separate storage cluster.
