Licensing Data Recovery Environments ( Oracle Licensing DataGaurd )
Oracle Licensing DataGaurd From Web Licensing Data Recovery Environments In today's data and information intensive economy, businesses need continuous access to mission-critical information. IT departments must not only manage the rapid growth of business information but they must also keep this information available and protected. That's why every business has data recovery and business continuance plans. This document will help you in understanding how to license Oracle programs in such environments. Data Recovery environments are usually deployed using the following two methods: a) Deploying a clustered environment such as Failover or b) Copying, Synchronizing or Mirroring of the data and/or program files (such as Physical DB files, Binaries, Executables). Data Recovery using Clustered Environments (Failover) The failover data recovery method is an example of a clustered deployment, where multiple nodes/servers have access to one Single Storage/SAN. In such cases your license for the programs listed on the US Oracle Technology Price List (http://www.oracle.com/corporate/pricing/pricelists.html) is eligible for the 10-day rule, which includes the right to run the licensed program(s) on an unlicensed spare computer in a failover environment for up to a total of ten separate 24-hour periods in any given calendar year (for example, if a failover node is down for two hours on Tuesday and three hours on Friday, it counts as two 24-hour periods). The above right only applies when a number of physical or logical machines as defined in Oracle's Partitioning Policy (detailed in https://www.oracle.com/assets/partitioning-070609.pdf) are arranged in a cluster and share one logical disk array located in a single data center. When the primary node fails, the failover node acts as the primary node. Once the primary node is repaired, you must either switch back or designate that repaired server as the failover node. Once the failover period has exceeded ten 24-hour periods, the failover node must be licensed. In addition, only one failover node per clustered environment is at no charge even if multiple nodes are configured as failover. Downtime for maintenance purposes counts towards the ten separate 24-hour periods limitation. When licensing options on a failover environment, the options must match the number of licenses of the associated database. Additionally,when licensing by Named User Plus, the user minimums are waived on one failover node only. Any use beyond the right granted in this section must be licensed separately. In a failover environment, the same license metric must be used for the production and failover nodes when licensing a given clustered configuration. Data Recovery Environments using Copying, Synchronizing or Mirroring Standby and Remote Mirroring are commonly used terms to describe these methods of deploying Data Recovery environments. In these Data Recovery deployments, the data, and optionally the Oracle binaries, are copied to another storage device. In these Data Recovery deployments all Oracle programs that are installed and/or running must be licensed per standard policies documented in the Oracle Agreement. This includes installing Oracle programs on the DR server(s) to test the DR scenario. Licensing metrics and program options on Production and Data Recovery servers must match with two exceptions: 1) Real Application Clusters (RAC) - Oracle RAC does not need to be licensed on the Data Recovery server unless used on the Data Recovery server; 2) For Production servers licensed using one of the Oracle Data Management Cloud Services listed in this document (http://www.oracle.com/us/corporate/contracts/paas-iaas-universal-credits-3940775.pdf), only program options in use on the Production server must be licensed on the Data Recovery server. This document is for educational purposes only and provides guidelines regarding Oracle's Data Recovery policies in effect as of July 28th, 2020. It may not be incorporated into any contract and does not constitute a contract or a commitment to any specific terms. Policies and this document are subject to change without notice. This document may not be reproduced in any manner without the express written permission of Oracle Corporation. Testing For the purpose of testing physical copies of backups, your license for the Oracle Database includes the right to run the database on an unlicensed computer for up to four times, not exceeding 2 days per testing, in any given calendar year. The aforementioned right does not cover any other data recovery method - such as remote mirroring - where the Oracle program binary files are copied or synchronized.

cat << END
$(basename $0) Based on oratab, show nice tables of the installed and/or missing patches for some GI/DB Oracle Homes
You can then quickly find a missing patch across a RAC system
$(basename $0) will by default check all the nodes of a cluster (based on olsnodes) which requires ASM to be running
and oraenv to be working with the ASM aslias defined in oratab; If you have no ASM alias in oratab,
you may suffer from https://unknowndba.blogspot.com/2019/01/lost-entries-in-oratab-after-gi-122.html
You can specify a comma separated list of host or a file containing one host per line
$(basename $0) by default checks all the homes defined in oratab, you can use --grep/--home and --ungrep/--ignore to limit your home selection (see examples below)
$(basename $0) relies on opatch lspatches which must run as oracle user (and not root); if the script is started as root,
the opatch lspatches commands will be run after su - ${ORACLE} (see -u | --oracleuser for more on this)

-u | --oracleuser ) User to use to run opatch lspatches if the script is started as root, default is ${ORACLE}
