Amazon EC2 Oracle Snapshot Backup

The idea is first put oracle database in backup mode, start the ec2 snapshot process. At this point, we can put the database back to normal already.
I add 60 seconds wait to be on the safe side.

$ cat ebs_volume_snapshot.sh

#!/bin/bash
SCRIPT_HOME=/u01/app/oracle/scripts
ORACLE_HOME=/u01/app/oracle/product/11.2.0/xe

sqlplus -S / as sysdba << ABC1
alter database begin backup;
exit;
ABC1

$SCRIPT_HOME/ec2-automate-backup.sh -v "vol-11ba0c5d vol-3cba0c70" -k 3  -c $SCRIPT_HOME/cron-primer.sh

sleep 60

sqlplus -S / as sysdba << ABC2
alter database end backup;
exit;
ABC2

$ cat cron-primer.sh

#!/bin/bash -
# EC2_HOME required for EC2 API Tools
export EC2_HOME=/opt/aws/apitools/ec2
# JAVA_HOME required for EC2 API Tools
export JAVA_HOME=/usr/lib/jvm/jre
export PATH=/bin:/opt/aws/bin/
