Establishing a mandatory archive destination
When cloning a database using Database FlashSnap, the Oracle database must have at least one
mandatory archive destination.
If no mandatory archive destination is set, dbed_vmchecksnap results in this error message:
SFORA dbed_vmchecksnap ERROR V-81-5677 Could not find a mandatory,
primary and valid archive destination for database PROD.Please review
the LOG_ARCHIVE_DEST_n parameters and check V$archive_dest.
This example shows how to establish a mandatory archive destination using SQL*Plus:
alter system set log_archive_dest_1 =
'LOCATION=/ora_mnt/oracle/oradata/PROD/archivelogs MANDATORY [REOPEN]’
[scope=both];
For more information about Oracle parameters for archiving redo logs, see your Oracle
documentation.
Validating a Snapplan (dbed_vmchecksnap)
After creating a snapplan, the next steps are to validate the snapplan parameters and check
whether the snapshot volumes have been configured correctly for creating snapshots. If validation
is successful, the snapplan is copied to the repository. The snapplan is validated using the
dbed_vmchecksnap command with the -o validate option.
Consider the following prerequisites and notes before validating a snapplan:
Table 5-5 Validating Snapplan Requirements
The database must be up and running while executing the dbed_vmchecksnap command.Prerequisites
• The dbed_vmchecksnap command must be run as the Oracle database administrator.
• After validating the snapplan, you have the option of modifying the snapplan file to meet
your storage configuration requirements.
• When using dbed_vmchecksnap to validate the snapplan and storage, you can save the
validation output. The system administrator can use this information to adjust the storage
setup if the validation fails.
• If a snapplan is updated or modified, you must revalidate it. It is recommended that
snapplans are revalidated when changes are made in the database disk group.
• The dbed_vmchecksnap command can be used on the primary or secondary host.
• See the dbed_vmchecksnap(1M) manual page for more information.
Usage Notes
To validate a snapplan
1. Change directories to the working directory your snapplan is stored in:
# cd /working_directory
2. Validate the snapplan using the dbed_vmchecksnap command:
# /opt/VRTS/bin/dbed_vmchecksnap -S-D ORACLE_SID -H ORACLE_HOME -f
SNAPPLAN -o validate
