Creating a Snapplan (dbed_vmchecksnap)
The dbed_vmchecksnap command creates a snapplan that dbed_vmsnap uses to create a snapshot
of an Oracle database. The snapplan specifies snapshot scenarios (such as online, offline, or
instant).
You can name a snapplan file whatever you choose. Each entry in the snapplan file is a line in
parameter=argument format.
When using dbed_vmchecksnap to create or validate a snapplan, the following parameters are
set
Table 5-3 Parameter Values for dbed_vmchecksnap
ValueParameter
Specifies the snapshot version for this major release of SGeRAC.
SNAPSHOT_VERSION
The name of the host where the primary database resides.
PRIMARY_HOST
The name of the host where the database will be imported.
SECONDARY_HOST
The name of the VxVM disk group used by the primary database.
PRIMARY_DG
The name of the disk group containing the snapshot volumes.
The snapshot volumes will be put into this disk group on the primary host and
deported. The secondary host will import this disk group to start a clone database.
SNAPSHOT_DG
The name of the Oracle database. By default, the name of the Oracle database is
included in the snapplan.
ORACLE_SID
The full path of the archive logs.
There are several archive log destinations that can be used for database recovery if
you are multiplexing the archive logs. You must specify which archive log
destination to use.
It is recommended that you have the archive log destination on a separate volume
if SNAPSHOT_ARCHIVE_LOG is yes.
ARCHIVELOG_DEST
yes or no
Specifies whether to create a snapshot of the archive log volumes. Specify yes to
split the archive log volume mirrors and deport them to the secondary host. When
using the Oracle remote archive log destination feature to send the archive logs to
the secondary host, you can specify no to save some space.
Because the archive logs may not always be delivered to the secondary host reliably,
it is recommended that you specify yes.
SNAPSHOT_ARCHIVE_LOG
online or offline or instant
Specifies whether the database snapshot should be online, offline, or instant.
• If the snapshot is created while the database is online, the dbed_vmsnap
command will put the tablespaces into backup mode. After dbed_vmsnap finishes
creating the snapshot, it will take the tablespaces out of backup mode, switch
the log files to ensure that the extra redo logs are archived, and create a snapshot
of the archived logs.
• If the database if offline, it is not necessary to put the tablespaces into backup
mode. The database must be shut down before creating an offline snapshot.
• If the database snapshot is instant, dbed_vmsnap will skip putting the tablespace
into backup mode.
NOTE: If SNAPSHOT_MODE is set to offline or instant, a two-host configuration is
required and the -r relocate_path option is not allowed.
SNAPSHOT_MODE
The default value is database and cannot be changed.
Specifies the database object for which you want to create a snapshot.
