Mask-At Source or Mask During Subset
To mask confidential data for non-production use, enterprises needed to make a copy of the production database and then mask the data before sharing it with non-production users such as testers or developers. Masking at the source or masking while subsetting at the source database allows enterprises to provision a secure and reduced size test system directly from the production database without the need for a full production database copy.

AN ANALOGY ON THE ARCHITECTURES OF ORACLE AND ANIMATED LIVING BEING
An Analogy on the Architectures of Oracle and Animated Living Being
- By SrinivasMaddali
Prologue:
To take Oracle more closely than it is to its DBA to Developer, it is necessary that we speak in the terms of audience than in terms of Oracle.
ORACLE 12C NEW FEATURES 06 – AQ ENHANCEMENTS
SrinivasMaddali
Oracle Database Advanced Queuing Enhancements
The following sections describe Oracle Database Advanced Queuing (AQ) improvements.
ARCHIVED LOG FILES
What is an archived redo log file?
Oracle enables you to save filled groups of online redo log files to one or more offline destinations, known collectively as the archived redo log, or more simply archive log.
HOW TO TURN ARCHIVING ON AND OFF???
Doc Id on Metalink 69739.1
Turning Archiving On and Off
You set a database's initial archiving mode as part of database creation.
Usually, you can use the default of NOARCHIVELOG mode at database creation because there is no need to archive the redo information generated at that time.
TELL ME HOW MANY BACKGROUND PROCESSES HELP ORACLE INSTANCE TO RUN?
SMON
The System Monitor carries out a crash recovery when a crashed instance is started up again. It also cleans temporary segments. SMON checks the SCN in all datafile headers when the database is started.
CATLOG CREATION
Discussion on creation and use of catalog
(Example scripts as provided by Oracle)
What is to be done in Oracle Version 8.1.x?
SVRMGR> spool create_rman.log
SVRMGR> connect internal
SVRMGR> create user rman identified by rman
temporary tablespace temp
default tablespace rcvcat quota unlimited on rcvcat;
CONTROL FILES
How to manage Control Files??
We have discussed briefly the role of control file in an Oracle Database.
The control file of an Oracle database is created at the same time as the database.
A control file is a small binary file that records the physical structure of the database
CONTROL STRUCTURES
PL/SQL Tutorials - CONTROL STRUCTURES
In this we try to understand IF-THEN, IF-THEN-ELSE and IF-THEN-ELSIF-THEN.
Let me remind you that Boolean means to me not TRUE/FALSE but also NULL. This is true always.
CREATE DATA BASE
(1) you must be logged in as SYS with SYSDBA privilege invoked.
(2) you must have edited initmynewdb.ora file to spawn an oracle instance
(3) and you started the oracle instance in nomount mode.
(4) after the database is created you are also to create the medata and plsql packages
CSSCAN
(Character Set Scanner)
Introduced in Oracle 8iR2
Metalink Doc Id 123670.1
Before altering the character set of a database, check the convertibility of the data before converting. Character set conversions can cause data loss or data corruption.
DATA FILES
How to manage datafiles??
The earlier discussions are on the control files and redo log files as also archived log files. Control files and redo log files are part of the database files and they count as part of the number of data files a database can have.
DATABASE CREATION
Step 01
Decide on the location of
Three control files (minimum) on different disks/ drives/volumes
Three groups of redo log files, with each group having two members (minimum) on different disks/ drives/volumes Create a file structure for the data files
ORACLE 12C DATABASE AUTHENTICATION METHODS FOR THE ADMINISTRATORS
The purpose of differentiating these authentication methods was to differentiate the roles and also secure the database and the docs read “Database Administrators can authenticate database administrators through the data dictionary, (using an account password) like other users. Keep in mind that database passwords are case-sensitive.”
DATABASE TESTING AND PATCH QUERYING
Srinivas Maddali
Database Testing
The following sections describe database testing features.
Mask-At Source or Mask During Subset
To mask confidential data for non-production use, enterprises needed to make a copy of the production database and then mask the data before sharing it with non-production users such as testers or developers.
DBNEWID
D:oracleOra92bin>nid help=yes
DBNEWID: Release 9.2.0.6.0 - Production
Copyright (c) 1995, 2002, Oracle Corporation. All rights reserved.
DBNEWID is a database utility that can change the internal database identifier (DBID) and the database name (DBNAME) for an operational database.
HOW ORACLE WORKS
The following example illustrates an Oracle configuration where the user and associated server process are on separate machines (connected via a network).
HOW TO REMOVE STREAM
01. remove streams
EXEC DBMS_STREAMS_ADM.REMOVE_STREAMS_CONFIGURATION();
02. drop queue tables
select OWNER,NAME,QUEUE_TABLE from dba_queues where owner='';

ORA-04030 AND ORA-04031
ORA-04031 indicates that shared pool configuration is not sufficient to meet that instance requirements. So, shared pool is to be increased. ORA-04031 can be caused if the User profile is NOT as required by Oracle on Oracle Sun Solaris, AIX and HP. I have not used True Unix and hence I do not know.
ORA-04045
What is being done?
I had Oracle 9.2.0.5.0 database
I had a remote 9.0.1.3.1 database
I was testing replication.
I saw some invalid SYSTEM schema replication objects in 9.0.1.3.1

RECOVER_DATABASE
Recover database
(1) Required Privileges
You must have the ALTER DATABASE system privilege. To specify the RECOVER clause, you must also have the SYSDBA system privilege.
(2) Using Parallel Recovery Processes:
RECOVERY CATLOG
Setting Up a Recovery Catalog
Oracle 9.1.0.5.0 version
A recovery catalog is not necessary when using RMAN. To use a recovery catalog, you need to create a schema in a recovery catalog database. The catalog will be located in the default tablespace of the scheme. Note that SYS cannot be the owner of the catalog.
REDO LOG FILES
What Oracle says on Redo Log File???
The most crucial and vital structure for recovery operations is the online redo log, which consists of two or more pre-allocated files that store all changes made to the database as they occur.
REDO RECORDS
How to Control the Writing of Redo Records?
For some database operations, it is possible to control whether redo records are generated. Suppressing redo generation can improve performance, and may be appropriate for easily recoverable operations.
REGENERATE DROPPED TABLE
Oracle 10G New Feature regenerate dropped table
Use the FLASHBACK TABLE statement to restore an earlier state of a table in the event of human or application error. The time in the past to which the table can be flashed back is dependent on the amount of undo data in the system.

SEGMENTS II - ROLLBACK SEGMENTS
This discussion is on managing the UNDO segments.
Undo is defined by oracle as:
Every Oracle database must have a method of maintaining information that is used to roll back, or undo, changes to the database.
SEGMENTS IV - PARTITIONED TABLES
Partitioned Tables
Introduced with Oracle8, Oracle partitioning has matured over the years, through Oracle8i and Oracle9i.
From the stage of stripping the datafiles across the disks for better IO
SEGMENTS PART I
Each tablespace hosts segments. There are many types of segments.
CACHE
CLUSTER
INDEX
INDEX PARTITION
INDEX SUBPARTITION
LOBINDEX
SEGMENTS PART V - INDEX ORGANIZED TABLES
Partitioning and IOT
In Oracle 8 and 8.1 Index Organized Tables (IOT) are partitioned on RANGE only. Oracle 9 enables IOT to have hash partitions also.
Before any further discussion on IOT let us recapitulate IOT concepts.
SEGMENTS PART VII TEMPORARY SEGMENTS
Oracle has tons of Info on Metalink read and use that as you evolve
Oracle over a period evolved the temporary segments and their usage. Evolution is from permanent tablespace with temporary contents to temporary tablespace with tempfile to temporary tabelspace groups. Most importantly all these evolutionary phases are still available depending upon choices.

Agenda
Immutable Tables in Oracle Database 19c and 21c
An immutable table is a tamper-proof, insert-only table with an associated table-level and row-level retention period. They are similar to blockchain tables, but the rows are not chained using cryptographic hashes.
Blockchain tables were introduced in 21c and backported to 19.10. Immutable tables were introduced to Oracle 21.3 and 19.11 at the same time, so it could be considered a 19c and 21c new feature.
When learning about immutable tables, be careful not to set excessively long retention periods, or you will have to wait a long time to drop your test tables.
Neural Networks
Neural Networks are a powerful machine learning algorithm, allowing you to create complex and deep learning neural network models to find hidden patterns in your data sets. Neural Networks are available with Oracle 18c and can be easily built and used to make predictions using a few simple SQL commands.
Blockchain Tables in Oracle Database 21c
A blockchain table is a tamper-proof, insert-only table with an associated table-level and row-level retention period. Rows are organised into chains, with each row containing a hash of the data contained in the row, and the hash of the previous rows data.
This feature has been backported to Oracle 19.10, but also requires patch 32431413 and the COMPATIBLE parameter set to 19.10.0 or later. From 19.11 the additional patch is not required.
When learning about blockchain tables, be careful not to set excessively long retention periods, or you will have to wait a long time to drop your test tables.
This Oracle GoldeGate Maximum Availability Architecture (MAA) migration solution provides step-bystep instructions to set up and migrate any 11g Release 2 and later Oracle database, from any system platform (e.g. AIX, HP UX, Linux), from a single tenant to a multitenant architecture, or from a database not using Transparent Data Encryption (TDE) to a TDE database.
These same MAA best practices are generally applicable while migrating between on-premises or cloud source and target database systems, although cloud-specific details will be outlined in a separate paper.
