Rapid Home Provisioning Server - Minimun Requirement

Ruggero Citton
Product Development- Architect

Introduction

Rapid Home Provisioning (RHP) represents a standard way for
provisioning, patching and update at organizational level, in a unified
manner, across all architectural layers of software infrastructure –
Oracle databases and custom software.

  • Rapid Home Provisioning is a method of deploying software homes from
    single cluster where you create, store and manage templates of Oracle
    homes as images - called gold images - of Oracle software. The DBA can
    make a working copy of any gold image and then provision that working
    copy to any RHP Client in a data center.
  • RHP is installed as part of Grid Infrastructure. Oracle Clusterware
    manages the components that form the Rapid Home Provisioning Server.
    These components include the RHP server itself, Grid Naming Service
    (GNS) which is used to advertise the location of the RHP server, a VIP
    to support HA-NFS (required if there are any clients that you want to
    provision to - whether you use NFS storage for the workingcopies or not)
    and Oracle ASM Cluster File System (ACFS) which is used to store
    snapshots of the working copies.
  • The gold images represent an installed home, whether that is an
    Oracle Database software home or some custom software home. The gold
    image is stored in an Oracle Automatic Software Management Cluster File
    System (Oracle ACFS).
  • Metadata describing an installed home is stored as an image series
    in the Management Repository. The Management Repository (or Management
    Database MGMTDB) is created when installing Oracle Grid Infrastructure.

Rapid Home Provisioning is a very powerful feature without demanding so much power.

RHP Server Software Requirements

You need to install Oracle Grid Infrastructure 12.1.0.2 (and above) for a New Cluster (single node if High Availability is not required).

Note: Oracle Grid Infrastructure standalone (Oracle Restart) is not supported with RHP Server

RHP Server Memory Minimum Requirements

Ensure that your system meets the following memory requirements for
installing Oracle Grid Infrastructure for a New Cluster (single node if
High Availability is not required):

- At least 4 GB of RAM for Oracle Grid Infrastructure for a standalone server
- Swap Space Requirement
    --> Equal to the size of the RAM if RAM between 4 GB and 16 GB
    --> More than 16 GB if RAM is more then 16 GB

RHP Server Storage Minimum Requirements

Ensure that your system meets the following minimum disk space
requirements for installing Oracle Grid Infrastructure (single node if
High Availability is not required):
- At least 6.9 GB of disk space
- At least 1 GB of space in the /tmp directory.
- At least 100Gb of space in the ASM diskgroup used by RHP Server

RHP Server Network Minimum Requirements

- 1 Ethernet interface card for the Oracle Grid Infrastructure public network
- 1 Ethernet interface card for the Oracle Grid Infrastructure private network

RHP Server Network IP Minimum Requirements

- 1 Host IP
- 1 GNS VIP (without Zone Delegation) (*)
- 1 HA-VIP for RHP HANFS usage (*)
- 1 host VIP for Oracle Grid Infrastructure
- SCAN IPs:
    1 single name that resolves to 3 IP addresses on the same subnet as your default public network (if DNS is in use)
    1 single name that resolves to 1 IP addresses in "/etc/hosts" (if the DNS is not in use)

(*) The requirement for NFS applies if there are any clients that you
want to provision to - whether you use NFS storage for the
workingcopies or not. (Even if you use a local file system on the
client, RHP Server uses a temporary NFS mount point to do the transfer,
so the HA-VIP is required).
The same is true for GNS: if you have
zero clients, you don't need GNS or HAVIP. If you have one or more
clients, you need GNS and VIP.

Software License needs

Rapid Home Provisioning (RHP) is a feature of Grid Infrastructure
12.1 and later. The architecture consists of a Server and one or more
Clients. The Server may provision and patch Homes locally without any
extra license needed. If Clients are configured, they require Database
Lifecycle Management Pack licensing.
