To create a multi-mirror snaphot
1
Add the second mirror and DCO log. When allocating storage for the second
mirror and DCO logs, make sure the snap volumes are splittable. If snap
volumes are not splittable, dbed_vmchecksnap fails with appropriate errors.
# vxsnap -g dg_a addmir dg_a_vol1 alloc=dg_a03
2
Tag the newly added mirror with the same tag as that of the first mirror.
Assume that the volume has fastresync = on, has dcolog = on, and already
has one SNAPDONE mirror and is tagged with .
# vxedit -g dg_a set putil2=dbed_flashsnap dg_a_vol1-03
3
Add the SNAPSHOT_MIRROR keyword to the snapplan. Here is a sample snapplan.
SNAPSHOT_VERSION=5.0
PRIMARY_HOST=host1
SECONDARY_HOST=host1
PRIMARY_DG=PRODdg
SNAPSHOT_DG=SNAP_PRODdg
ORACLE_SID=PROD
ARCHIVELOG_DEST=/prod_ar
SNAPSHOT_ARCHIVE_LOG=yes
SNAPSHOT_MODE=online
SNAPSHOT_PLAN_FOR=database
SNAPSHOT_PLEX_TAG=dbed_flashsnap
SNAPSHOT_VOL_PREFIX=SNAP_
ALLOW_REVERSE_RESYNC=no
SNAPSHOT_MIRROR=2
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_vmchecksnapresults 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.
