Before attempting to install or remove the LifeKeeper Oracle Recovery Kit, you must understand the hardware and software requirements and the installation and removal procedures.
Be sure that your configuration meets the following requirements:
Servers. The Recovery Kit requires two or more supported computers configured in accordance with LifeKeeper requirements described in the LifeKeeper Technical Documentation and the LifeKeeper for Linux Release Notes.
Shared Storage. Oracle databases must reside on a shared disk in a LifeKeeper environment. Depending on your shared storage architecture, the appropriate LifeKeeper shared storage or multipath storage kit will need to be installed on each node in your cluster. In the example of NFS backed database storage, installation of the LifeKeeper NAS Kit is necessary. If you are planning to use LifeKeeper in a data replication (mirroring) environment, see the SIOS DataKeeper Administration Guide. If you are using LifeKeeper in a network attached storage (NAS) environment, see the LifeKeeper Network Attached Storage Recovery Kit Administration Guide.
LifeKeeper Software. You must install the same version of LifeKeeper software and any patches on each server. Please refer to the LifeKeeper for Linux Release Notes and LifeKeeper for Linux Technical Documentation for specific LifeKeeper requirements.
LifeKeeper IP Recovery Kit. This Recovery Kit is required if remote clients will be accessing the Oracle Database. You must have the same version of this Recovery Kit on each server.
IP Network Interface. Each server requires at least one Ethernet TCP/IP-supported network interface. In order for IP switchover to work properly, user systems connected to the local network should conform to standard TCP/IP specifications.
Note: Even though each server requires only a single network interface, you should use multiple interfaces for a number of reasons: heterogeneous media requirements, throughput requirements, elimination of single points of failure, network segmentation, and so forth.
TCP/IP Software. Each server also requires the TCP/IP software.
Oracle Software. Each server must have the Oracle software installed and configured before you can configure LifeKeeper and the LifeKeeper Oracle Recovery Kit. The same version should be installed on each server. Consult the LifeKeeper for Linux Release Notes or your sales representative for the latest release compatibility and ordering information.
You should refer to the LifeKeeper for Linux Installation Guide for specific instructions on how to install or remove the LifeKeeper Oracle Recovery Kit.
