The hardware configuration necessary for operating a system that uses HA Monitor Kit depends on HA Monitor. For details, see the description under Required hardware in the manual HA Monitor (for Linux(R)).
This subsection explains the hardware configuration elements that require close attention when using HA Monitor Kit.
A shared disk is used to store the data that the server shares between the active system and the standby system. In Oracle, the following files that make up a database are stored on the shared disk:
Also, the flash recovery area must specify a path on the shared disk.
When you install Oracle on a shared disk, you can choose to share the software between the active system and the standby system. You can also install Oracle on a local disk.
A local disk is used as a host-specific disk device not shared between hosts on which Oracle and HA Monitor Kit are installed. You can also install Oracle on a shared disk.
For details about Oracle installation, see 3.2.4 Oracle installation.
A LAN is used by a client to connect to the database.
