Oracle Database Licensing Insights and Tips

01

With this presentation we will take a look at general Oracle database licensing

and how the Oracle database tracks feature usage.

This can be helpful in preparing for a LMS audit or for taking inventory before renewing an Oracle contract.

As most people close to Oracle know, licensing and product discovery can be complex.

We would like share some practical experiences with a LMS audit.

Oracle’s technology products are primarily licensed using two metrics: Named User Plus or Processor.

Named User Plus

• Based on users and non-human operated devices accessing the Database

• Used in environments where users can be counted

Processor

• Based on the number of processors cores (EE) or sockets (SE, SE1 and SE2) in the server where the Database is installed and/or running. Standard Edition can only be licensed on servers, that have a maximum capacity of sockets, (e.g. SE with 4, SE1&2 with 2 sockets ).

• Used in environments where users are uncountable

Database Licensing in a Virtual Environment

Installing an Oracle instance on a single virtual machine in a VM environment requires licensing all physical processor-cores on the host supporting it.

Audit – experiences and procedure recommendation

02

June, 5-6 2019

Every seven days (default behavior) the view dba_feature_usage_statistics updates with what features have been used in the database. You can manually kickoff a refresh by running the procedure below

A description of dba_feature_usage_statistics can be shown by

Oracle support document 1317265.1 provides the scripts necessary to query this table.

This document is a must read for any DBA involved in Oracle licensing.

Oracle DB usage

EXEC DBMS_FEATURE_USAGE_INTERNAL.exec_db_usage_sampling(SYSDATE);

1. Inform all related parties including your purchase department

2. Stopp all new orders in preperation to have negotiation backlogs

3. Run an internal check and in case of any doubts plan to setup your DB from scratch before you give any access norsending script outputs to Oracle or their partners

4. Get in contact with a Licensing or Audit consultant

5. Inform your application partners

6. Be prepared! Setup a licence management and run a internal compliance check once a year to avoid running in longterm usage of advanced features you are not paying for.

Oracle DB Audit request – and now?

If you have received an audit report from Oracle and are shocked at the findings, feel like you are being bullied by Oracle over non-contractual licensing claims, or are ready to explore migrating to another platform altogether, we would be happy to discuss your options.

Postgres

https://www.postgresql.org/

PostgreSQL: The World's Most Advanced Open Source Relational DatabasePostgreSQL is a powerful, open source object-relational database system with over 30 years of active development that has earned it a strong reputation for reliability, feature robustness, and performance. There is a wealth of information to be found describing how to install and use PostgreSQL through the official documentation. The PostgreSQL community provides many helpful places to become familiar with the technology….

Ask the Techies

„Easy to learn – similar to Oracle“

„Dumps to textfiles are easy“

„Tons of resources in the net“ „I prefer psql over sqlplus“

„EDB support is responsive – we got a patch release fixing a bugdiscovered by T-Systems within 6 weeks“

„Postgres is stricter with data types – we had to clean up ourlazy Oracle type casts“

„open for other open source toolse. g. Grafana plugin“

„Oracle and EDB differ in SQL for DDL statements“
