8.1 Oracle Database Changes

Oracle Database 12c introduces changes that affect Oracle Database in general.

This section contains these topics:

8.1.1 Deprecation of catupgrd.sql Script and Introduction of New catctl.pl Utility

Oracle Database 12c introduces the new Parallel Upgrade Utility, catctl.pl. This utility replaces the catupgrd.sql script that was used in earlier releases. Although you can still use the catupgrd.sql script, it is deprecated starting with Oracle Database 12c and will be removed in future releases. Oracle recommends database upgrades be performed with the new Parallel Upgrade Utility, catctl.pl.

If you choose to run the catupgrd.sql script instead of running catctl.pl, doing so now requires an additional input parameter as follows:

SQL> catupgrd.sql PARALLEL=NO

If you run catupgrd.sql without the parameter, then Oracle displays the following error message:

NOTE
 
The catupgrd.sql script is being deprecated in the 12.1 release of 
Oracle Database. Customers are encouraged to use catctl.pl as
the replacement for catupgrd.sql when upgrading the database dictionary.
 
                cd $ORACLE_HOME/rdbms/admin
                $ORACLE_HOME/perl/bin/perl catctl.pl -n 4 catupgrd.sql
 
Refer to the Oracle Database Upgrade Guide for more information.
 
This database upgrade procedure must be called with the following
argument when invoking from the SQL prompt:
 
                @catupgrd.sql PARALLEL=NO

See Also:

"About the New Parallel Upgrade Utility for Oracle Database" for information about catctl.pl and how to run it

8.1.2 Desupport of Oracle Enterprise Manager Database Control

See Also:

Oracle GoldenGate documentation for information

8.2.3 Desupported Features in Oracle Data Mining

The following Oracle Data Mining features are desupported in Oracle Database 12c:

  • The Oracle Data Mining Java API is no longer available. The programmatic interfaces to Oracle Data Mining 12c consist of two PL/SQL packages, DBMS_DATA_MINING and DBMS_DATA_MINING_TRANSFORM, and a family of SQL language functions for scoring data.

    See Also:

    Oracle Data Mining User's Guide for information about the Data Mining PL/SQL packages
  • The Adaptive Bayes Network (ABN) algorithm is no longer available. The Decision Tree algorithm replaces ABN in Oracle Data Mining 12c.

    See Also:

    Oracle Data Mining Concepts for information about the Decision Tree algorithm

8.2.4 Changes to Upgrading Oracle Data Mining Models

Starting with Oracle Database 12c, Oracle is desupporting the Data Mining Java API and the Adaptive Bayes Network (ABN) algorithm. Therefore, models created by the Oracle Data Mining Java API cannot be upgraded from Oracle Database release 11g to Oracle Database 12c. All other models and metadata are upgraded automatically during the upgrade from release 11g to Oracle Database 12c. ABN models can be upgraded, but you cannot use them in an Oracle Database 12c database. You must drop ABN models either before the upgrade or afterward. You can replace ABN models by building new classification models in the Oracle Database 12c database.

See Also:

Oracle Data Mining User's Guide for information about the Data Mining API and data mining models

8.2.5 Desupport of OLAP Catalog (AMD)

Starting with Oracle Database 12c, the Common Warehouse Metamodel (CWM) standard is desupported for the OLAP catalog (AMD). This support was deprecated in Oracle Database 11g Release 2 (11.2). If your existing database has CWM metadata in the OLAP catalog and you upgrade to Oracle Database 12c, then the upgraded database has the AMD component. If the database you upgrade does not have the AMD component, then the upgraded Oracle Database 12c database also does not have the AMD component because new installations for Oracle Database 12c do not include AMD. If your database has the AMD component and you want to remove it, then run the ORACLE_HOME/olap/admin/catnoamd.sql script before or after upgrading.

Note:

If the OLAP catalog exists in the database you are upgrading, you may see AMD OLAP Catalog OPTION OFF and invalid CWM OLAP objects. You can safely ignore the invalid OLAP objects as they are not needed.

See Also:

8.3 Oracle Database Security Changes

Oracle Database 12c includes changes to security features in Oracle Database Vault and Oracle Data Guard and other areas. This section contains these topics:

8.3.1 Changes to Security Auditing Features

The auditing functionality has been redesigned in Oracle Database 12c. When you create a new database with Oracle Database 12c, the full set of auditing enhancement features are automatically available. If you upgrade from an earlier release, then you are given the option of using some of the new audit features and the audit functionality from the release from which you upgraded. Oracle strongly recommends that you migrate to the full set of the latest audit features.

See Also:

8.3.2 Deprecations for Oracle Label Security

The following Oracle Label Security features are deprecated in Oracle Database 12c, and may be desupported in a future release:

8.3.3 Deprecated DBMS_NETWORK_ACL_ADMIN PL/SQL package Procedures

In Oracle Database 12c, the following procedures from the DBMS_NETWORK_ACL_ADMIN PL/SQL package are deprecated:

  • CREATE_ACL

  • ADD_PRIVILEGE

  • DELETE_PRIVILEGE

  • ASSIGN_ACL

  • UNASSIGN_ACL

  • DROP_ACL

  • ASSIGN_WALLET_ACL

  • UNASSIGN_WALLET_ACL

  • CHECK_PRIVILEGE

  • CHECK_PRIVILEGE_ACLID

See Also:

Oracle Database Security Guide for inormation about managing fine-grained access in PL/SQL Packages and Types

8.3.4 Deprecation of IGNORECASE and SEC_CASE_SENSITIVE_LOGON

The IGNORECASE argument of ORAPWD and the SEC_CASE_SENSITIVE_LOGON system parameter are deprecated in Oracle Database 12c. By default, passwords in Oracle Database 12c are case sensitive.

See Also:

Oracle Database Security Guide for more information about configuring authentication and password protection

8.3.5 Deprecation of SQLNET.ALLOWED_LOGON_VERSION Parameter

The SQLNET.ALLOWED_LOGON_VERSION parameter is deprecated in Oracle Database 12c. This parameter has been replaced with two new Oracle Net Services parameters:

8.3.5.1 Upgrading a System that Did Not Have SQLNET.ALLOWED_LOGON_VERSION Parameter Setting

If you are upgrading a system that did not have a SQLNET.ALLOWED_LOGON_VERSION parameter setting (that is, it was using the default 8), then you might need to set the value of the SQLNET.ALLOWED_LOGON_VERSION_SERVER to 8 in the upgraded Oracle Database 12c server to maintain compatibility with clients on earlier releases. Otherwise, if no setting for SQLNET.ALLOWED_LOGON_VERSION_SERVER (or the deprecated SQLNET.ALLOWED_LOGON_VERSION) parameter is made in the upgraded Oracle Database 12c server, then the new default value becomes 11 in the new Oracle Database 12c.

The effect of the new default value of 11 for SQLNET.ALLOWED_LOGON_VERSION_SERVER in Oracle Database 12c is that clients using Oracle Database release 10g and later can connect to the Oracle Database 12c server. Clients using releases earlier than Oracle Database release 11.2.0.3 that have not applied critical patch update CPUOct2012 or later patches must use the 10g password version.

Using a setting of 12 is most secure. However, this setting only permits Oracle Database 12c clients to connect.

See Also:

Oracle Database Readme for the topic "Protection Against Password-Guessing Attacks" and Oracle Database Net Services Reference for information about SQLNET.ALLOWED_LOGON_VERSION_SERVER

8.3.6 AUDIT_ADMIN and AUDIT_VIEWER Roles Note

In Oracle Database 12c, two roles may exist in your database that affect upgrading: AUDIT_ADMIN and AUDIT_VIEWER.

The Pre-Upgrade Information Tool and DBUA perform a pre-upgrade check to make sure such users or roles do not exist in the database. Oracle recommends that you do not use these names in your databases. If these users or roles exist, then you should rename or drop them as appropriate before upgrading to Oracle Database 12c.

See Also:

Oracle Database Security Guide for information on configuring privilege and role authorization for database security

8.3.7 Deprecation of Windows NTS Authentication Using the NTLM Protocol

Windows users can no longer authenticate using the NTS adaptor on Windows clients and servers that require the NT Lan Manager (NTLM) protocol. Because of security vulnerabilities, NTLM is deprecated as of Oracle Database 12c. Windows users can still use Kerberos. NTLM is still used for local user authentication, and in cases in which the database service runs as a local user.

See Also:

Oracle Database Platform Guide for Microsoft Windows for information on changes that affect the Windows platform in this release

8.3.8 Deprecation of Public Key Infrastructure for Transparent Data Encryption

Public Key Infrastructure (PKI) is deprecated for Transparent Data Encryption (TDE) in Oracle Database 12c. To configure TDE, use the ADMINISTER KEY MANAGEMENT SQL statement. Other implementations of PKI are not affected.

See Also:

Oracle Database Advanced Security Administrator's Guide for information about configuring TDE

8.3.9 Desupported Cipher Suites for Secure Sockets Layer (SSL)

Oracle Advanced Security has desupported the following cipher suites in Oracle Database 12c:

  • SSL_DH_anon_WITH_DES_CBC_SHA

  • SSL_RSA_EXPORT_WITH_DES40_CBC_SHA

  • SSL_RSA_EXPORT_WITH_RC4_40_MD5

  • SSL_RSA_WITH_DES_CBC_SHA

See Also:

Oracle Database Security Guide for information about the supported SSL cipher suites

8.3.10 Desupport of Database Rules Manager (RUL) and Expression Filter (EXF)

Starting with Oracle Database 12c, the Expression Filter (EXF) and Database Rules Manager (RUL) features are desupported. If you are using Rules Manager, Oracle recommends that you consider migrating to Oracle Business Rules, a component of Oracle Fusion Middleware. The Continuous Query Notification feature of Oracle Database replaces Expression Filter.

This script is executed by the upgrade process. If you want to remove these components before upgrading, then you can run the catnoexf.sql script before the upgrade. The catnoexf.sql script is located under ORACLE_HOME/rdbms/admin/.
