Integrating SAP R/3 and Data Protector

Configuring an SAP R/3 Backup

	influences (such as mount prompts),
	and is therefore best for
	environments with large libraries of
	the same quality. Each subset is
	backed up by one Data Protector
	sapback program, thus allowing
	concurrent backup of all subsets of
	the same type. Data Protector
	automatically stores backup speed
	information in the speed section of
	the Data Protector integration
	configuration file on the Cell
	Manager. It uses this information to
	optimize backup time.
	This type of balancing may lead to
	non-optimal grouping of files in the
	case of online backup, or if the speed
	of backup devices varies significantly
	among devices.
Balancing: Manual	Manual balancing optimizes backups
	by allowing you to group files into
	subsets and back up these subsets
	using specific devices. See “Manual
	Balancing of Files into Subsets” on
	page 193 for more information.
Balancing: None	No balancing is used. The files are
	backed up in the same order as they
	are listed in the internal Oracle
	database structure. To check the
	order use the Oracle Server Manager
	SQL command: select * from
	dba_data_files
Pre-exec	Specifies an object pre-exec command
	with options that will be started on
	the SAP R/3 Database Server before
	backup. The command/script is
	started by Data Protector
	omnisap.exe and has to reside in the
	<Data_Protector_home>\bin
	(Windows systems), /opt/omni/bin
