NOTE:
This variable is not supported on EMC.
The default value is 0. Possible values are 0 and 1.
If an offline backup is performed using the Data Protector SAP R/3 integration, the
variable is ignored and the integration behaves as if the variable was set to 1.
Instant Recovery
The instant recovery process depends on whether the control file and redo logs reside
on the same disk array source volume as datafiles or not:
• If this variable is set to 0 (default), during a ZDB session, Data Protector creates
target volumes only for the source volumes containing Oracle datafiles. Target
volumes for source volumes containing Oracle control file and Oracle online redo
logs are not created.
For Oracle proxy-copy or backup set ZDB and restore concepts when this variable
is set to 0, see “Oracle backup set ZDB concepts” on page 39 and “Oracle
proxy-copy ZDB concepts” on page 44. For SAP R/3 backup and restore concept
when this variable is set to 0, see “Integration concepts” on page 164.
• If this variable is set to 1, Data Protector creates target volumes for all source
volumes containing Oracle datafiles, Oracle control file, and if Oracle integration
is used, Oracle online redo logs.
IMPORTANT:
If the ZDB_ORA_INCLUDE_CF_OLF variable is set to 1 the control files and redo logs
are overwritten during instant recovery.
Opening the Database on the Backup System
To successfully open the database on the backup system for other purposes than Data
Protector, note:
• With Oracle proxy-copy ZDB method, set this variable to 1.
• With Oracle backup set ZDB method, used with the Oracle integration, you can
always open the database on the backup system.
