Application Agent supports mutual standby cluster configurations (Active-Active) as well as operational
standby cluster configurations (Active-Passive).
For details on cluster configurations see “ Operation-standby cluster configuration ” on page 43 or
“ Mutual-standby cluster configuration ” on page 44.
In a cluster environment using Microsoft Cluster Service or Windows Server Failover Clustering, you
can select whether to perform data restoration while cluster resources that monitor the DBMS are in
the online state or in the offline state. For a restore operation in which the cluster resources are in the
offline state, you need to take all the databases that are using the DBMS services offline. However,
for a restore operation in which the cluster resources are in the online state, you only need to take
offline the databases that are involved in the restore operation.
Depending on the storage system type and the functionality of the OS, you might not be able to
perform a restore operation while the cluster is online.
For details on how to perform a restore operation while the cluster resources are online, see “ Setting
up restoration while cluster resources are online ” on page 111.
Reducing workload by using commands
Application Agent provides two types of commands: basic and extended commands.
Basic commands are used to perform backups, restore operations, and other operations on backup
data, as well as for setting up Application Agent environments.
Execute basic commands in combination to perform Application Agent operations. For example, if
you want to perform a tape backup you must execute two commands in combination: a basic command
for mounting the primary volume to the secondary volume, and then another command for backing
up the data on the secondary volume to a tape device.
Application Agent provides scripts that can automatically execute a series of commands. These scripts
are called extended commands. Extended commands make it easier for you to perform backup tasks
that use multiple Application Agent commands.
Data management on another storage systems
Application Agent allows you to manage data that is on another storage system (hereafter referred
to as a remote site).
Application Agent allows you to back up and restore secondary volumes to and from a local site (the
storage system where the primary volume resides) and a remote site (a storage system different from
the one where the primary volume resides).
The figure below illustrates the relations between physical volumes and a local site or a remote site.
