- A Troubleshooting SGeRAC
NOTE: In a HA environment, you must modify the default snapplan, use the virtual host name
defined for the resource group for the PRIMARY_HOST and/or SECONDARY_HOST, and run
validation.
• In the following example, a snapplan, snap1, is validated for a snapshot image in a
single-host configuration. The primary host is host1 and the working directory is /export/
snap_dir.
# cd /export/snap_dir
# /opt/VRTS/bin/dbed_vmchecksnap -S PROD -H /oracle/product/10g -f
snap1 -o validate
PRIMARY_HOST is host1
SECONDARY_HOST is host1
The version of PRIMARY_DG-PRODdg is 110.
The primary diskgroup PRODdg is a shared disk group
SNAPSHOT_DG is SNAP_PRODdg
SNAPSHOT_MODE is online
The database is running in archivelog mode.
ARCHIVELOG_DEST is /prod_ar
SNAPSHOT_PLAN_FOR is database
SNAPSHOT_ARCHIVE_LOG is yes
ARCHIVELOG_DEST=/prod_ar is mount on /dev/vx/dsk/PRODdg/prod_ar.
Examining Oracle volume and disk layout for snapshot
Volume prod_db on PRODdg is ready for snapshot.
Original plex and DCO log for prod_db is on PRODdg01.
Snapshot plex and DCO log for prod_db is on PRODdg02.
SNAP_PRODdg for snapshot will include: PRODdg02
ALLOW_REVERSE_RESYNC is no
The snapplan snap1 has been created.
• In the following example, a snapplan, snap2, is validated for a snapshot image in a two-host
configuration. The primary host is host1, the secondary host is host2, and the working
directory is /export/snap_dir.
# cd /export/snap_dir
# /opt/VRTS/bin/dbed_vmchecksnap -S PROD -H /oracle/product/10g -f
snap2 -o validate
PRIMARY_HOST is host1
SECONDARY_HOST is host2
The version of PRIMARY_DG-PRODdg is 110.
The primary diskgroup PRODdg is a shared disk group
SNAPSHOT_DG is SNAP_PRODdg
SNAPSHOT_MODE is online
The database is running in archivelog mode.
ARCHIVELOG_DEST is /mytest/arch
SNAPSHOT_PLAN_FOR is database
SNAPSHOT_ARCHIVE_LOG is yes
ARCHIVELOG_DEST=/mytest/arch is mount on /dev/vx/dsk/PRODdg/arch.
Examining Oracle volume and disk layout for snapshot.
Volume arch on PRODdg is ready for snapshot.
Original plex and DCO log for arch is on PRODdg01.
Snapshot plex and DCO log for arch is on PRODdg02.
Volume prod_db on PRODdg is ready for snapshot.
Original plex and DCO log for prod_db is on PRODdg01.
Snapshot plex and DCO log for prod_db is on PRODdg04.
SNAP_PRODdg for snapshot will include: PRODdg02
ALLOW_REVERSE_RESYNC is no
The snapplan snap2 has been created.
