- A Troubleshooting SGeRAC
1. Change directories to the working directory you want to store your snapplan in.
# cd /working_directory
2. Create a snapplan with default values using the dbed_vmchecksnap command:
# /opt/VRTS/bin/dbed_vmchecksnap -S ORACLE_SID -H ORACLE_HOME -f
SNAPPLAN -o setdefaults -t host_name [-p PLEX_TAG]
3. Open the snapplan file in a text editor and modify it as needed.
• In this example, a snapplan, snap1, is created for a snapshot image in a single-host
configuration and default values are set. The host is named 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 setdefaults -t host1
Snapplan snap1 for PROD.

• In this other example, a snapplan, snap2, is created for a snapshot image in a two-host
configuration, and default values are set. 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 setdefaults -t host2
Snapplan snap2 for PROD.
