Oracle Database 12c comes with another significant change regarding using of Infrastructure Repository Databases and which could eventually make things more complicated. Before upgrade of Oracle Database, Database Administrator or a person responsible for Software Asset Management (and Licensing) should be familiar with changes in Licensing policy which come with new release and their implications. At first let me start with little comparison of probably the most frequently used versions in production 10gR2, 11gR2 and new 12cR1 to see an "evolution".

 

Here is an excerpt from the Licensing Guide and Enterprise Manager Licensing Information Guide for 10gR2:

"Infrastructure Repository Databases

A separate Oracle Database can be installed and used as a Recovery Manager (RMAN) repository without additional license requirements, provided that all the Oracle databases managed in this repository are correctly licensed. This repository database may also be used for the Oracle Enterprise Grid Control repository. It may not be used or deployed for other uses.

A separate Oracle Database can be installed and used as an Oracle Enterprise Manager Grid Control (OEM Grid Control) repository without additional license requirements, provided that all the targets (databases, applications, and so forth) managed in this repository are correctly licensed. This database may also be used for the RMAN repository. It may not be used or deployed for other uses.

Enterprise Manager Restricted-use License

Enterprise Manager includes a restricted-use license of the Oracle Database for use as the Oracle Management Repository only."

 

Here is the excerpt from the same guides for 11gR2:

"Infrastructure Repository Databases

A separate Oracle Database can be installed and used as a Recovery Manager (RMAN) repository without additional license requirements, provided that all the Oracle databases managed in this repository are correctly licensed. This repository database may also be used for the Oracle Enterprise Grid Control repository. It may not be used or deployed for other uses.

A separate Oracle Database can be installed and used as an Oracle Enterprise Manager Grid Control (OEM Grid Control) repository without additional license requirements, provided that all the targets (databases, applications, and so forth) managed in this repository are correctly licensed. This database may also be used for the RMAN repository. It may not be used or deployed for other uses.

 Enterprise Manager Restricted-use License

Enterprise Manager includes a restricted-use license of the Oracle Database for use as the Oracle Management Repository only.

Additional database options or additional servers for disaster recovery require separate licensing. Customers receive one single-instance database with the Grid Control, or RMAN, repository. To protect the repository with Data Guard, customers need to purchase a license for the standby site. To protect the repository with Oracle Real Application Clusters, customers must license the second node for the database, and both nodes require an Oracle Real Application Clusters license."

 

And here is the excerpt from the Licensing Information Guide guide for 12cR1:

"Infrastructure Repository Databases

A separate single instance Oracle Database can be installed and used as an infrastructure repository for RMAN, Oracle Enterprise Manager Cloud Control, Automatic Workload Repository (AWR) Warehouse, Global Data Services Catalog, and Grid Infrastructure Management Repository without additional license requirements, provided that all the targets are correctly licensed. It may not be used or deployed for other uses.

The infrastructure repositories for RMAN, Oracle Enterprise Manager Cloud Control, AWR Warehouse, and Global Data Services Catalog can be shared in one database, or deployed in separate databases. Enterprise Edition must be used for the infrastructure repository database(s).

If Oracle RAC is used for the infrastructure database, then Oracle RAC licenses for all servers, and Enterprise Edition licenses for all but the first server, are required.

If Data Guard is used for the infrastructure database, then an Enterprise Edition license for the standby server is required."

 

By comparison of above excerpts where you can see differences and changes regarding Infrastructure Repository Databases (later just IRD) for particular release. Since 12c (12cR1) there is a significant change regarding edition of the Oracle Database. Current 12c Guide simply says:

  1. If Standard Edition is used as IRD and you want to upgrade the repository database to 12c, then you have to migrate it to Enterprise Edition (later just EE)
  2. If current repository database is running in RAC mode, second or any additional node node is extra licensed (EE), moreover all servers must have RAC option licensed
  3. If current repository database is using Data Guard, a standby server has to be licensed extra licensed

 Well honestly in days of "cost cutting" where many companies are more and more looking at/for alternative solutions or even they are already in process of migration from Oracle to alternative solutions, claiming that "Oracle is expensive", then this is definitely backward step from the Oracle Corp. Oracle Database 12c comes with quite interesting and very useful features regarding Recovery Manager (RMAN) which is teasing us to use new version (of course for manipulation witch PDB's 12c version of RMAN is a must). But still there is a trade-off. To stay with the 11gR2 Recovery Manager thus use old 11gR2 Infrastructure Repository Database and as long as possible (forget about 12c RMAN features including multitenant) or even trying some other workarounds (e.g. relocate RMAN repository to some fully licensed servers or divide centralized repository (catalog) to several (repositories) catalogs and spread it across licensed HA databases) in order to prevent pay additional fees for high available Infrastructure Database. Honestly I would expect a little favor here.

But enough of blaming Oracle and let's see an example why Recovery Manager requires Enterprise Edition and what would happen when you try to use Standard Edition as a RMAN repository.

I have prepared fresh 12.1.0.1 Standard edition (12.1.0.2 isn't still available) using DB_NAME=RMANDB as a repository for RMAN catalog(s) in order to see whether EE is explicitly requested.

12.2.0.2 Enterprise Edition (EE) is used as "target" database using DBNAME=ORA12CR1

 

RMANDB:SQL> select banner from v$version where rownum = 1;

BANNER
--------------------------------------------------------------------------------
Oracle Database 12c Release 12.1.0.1.0 - 64bit Production


RMANDB:SQL> create user rman12 identified by rman default tablespace data;

User created.

RMANDB:SQL> grant recovery_catalog_owner, unlimited tablespace to rman12;

Grant succeeded.

 

Used rman command on future "target" DB host (12.1.0.2 EE):

RMAN> connect catalog rman12/rman@rmandb

connected to recovery catalog database
ORACLE error from recovery catalog database: ORA-06550: line 1, column 41:
PLS-00201: identifier 'DBMS_RCVCAT.GETPACKAGEVERSION' must be declared
ORA-06550: line 1, column 34:
PL/SQL: Statement ignored

If you got this error then you have to execute @?/rdbms/admin/dbmsrmansys.sql in order to fix this issue (I had to use this script from 12.1.0.2 home as my SE is 12.1.0.1).

 

Let's continue with creating a catalog:

RMAN> connect catalog rman12/rman@rmandb

connected to recovery catalog database

RMAN> create catalog;

error creating create_deleted_object_seq
ORACLE error from recovery catalog database: ORA-00439: feature not enabled: Partitioning

RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-06433: error installing recovery catalog

If you've got error as above, it means you aren't using Enteprise Edition as Partitioning requires EE or Partitioning option is not enabled.

 

RMAN> connect catalog rman12/rman@rmandb

connected to recovery catalog database

RMAN> create catalog

recovery catalog created
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-06004: ORACLE error from recovery catalog database: ORA-00439: feature not enabled: Fine-grained access control

And finally if you've got this one, it means that you aren't using Enteprise Edition (as Fine-grained access control is available in EE) and moreover you did very nasty thing in order to overcome previous error.

 New RMAN features rely on Partitioning, Virtual Private Database and Fine-grained access control (which is a part of VPD) which definitely require Enterprise Edition. If you are using centralized repository for RMAN, you should be aware of this important change which might cause additional costs. While VPD (Fine-grained access control) is not extra licensed , question whether Partitioning Option needs to be licensed remain unanswered. As always, you should contact your Oracle Sales representative in order to consult all question regarding licensing and to learn all implications according the changes.

RMAN>

 

As you can see using some (secret) tweaks I was able to create Oracle 12c Standard Edition for RMAN catalog. Of course this is not valid solution and it is not possible to use it for production as SE is not supported and it in fact violates the license. So no SE officially. But technically with couple of really nasty tweaks it is possible use SE as RMAN repository. ;-)
