Tivoli® Storage FlashCopy® Manager can
clone an Oracle Data Guard standby database.
To clone an Oracle Data Guard standby database,
on the Oracle Data Guard standby server complete the following steps:
This clone is a stand-alone Oracle database that can be opened
in read and write mode. You can use the cloning command optional function
-X preprocessing-configuration-filename and
-Y postprocessing-configuration-filename to
run preprocessing and postprocessing scripts on the cloned target
system. You can use shell or sql scripts.
Tip: If the
Tivoli Storage FlashCopy Manager profile
parameter
OVERWRITE_DATABASE_PARAMETER_FILE is
set to
YES, the
initDBSID.ora file
is copied from the Oracle Data Guard standby server to the clone target
system. This file contains Data Guard configuration information that
is not required by the clone instance and can cause problems. Therefore,
create a customized
initDBSID.ora file for the
Oracle clone instance and set the
Tivoli Storage FlashCopy Manager OVERWRITE_DATABASE_PARAMETER_FILE profile
parameter to
NO. You can copy the
initDBSID.ora file
and remove any specific Data Guard configuration information.
Typically
Oracle temporary tablespace files are not present
in the Data Guard standby server. If the temporary tablespace files
are on the same file systems as the Oracle data files, no additional
configuration is required by Tivoli Storage FlashCopy Manager.
If the temporary tablespace files are on a dedicated
file system or volume group, use the FLASH_DIR_LIST parameter
in the cloning section of Tivoli Storage FlashCopy Manager profile
to include these files. Use the FLASH_DIR_LIST parameter
to specify a fully qualified directory name and file name. This file
contains the mount points where the Oracle temporary files are located.
Use a separate line for each mount point. Then, Tivoli Storage FlashCopy Manager includes
the mount points and the corresponding volume groups in the FlashCopy cloning operation.
