Nabil Nawaz Oracle Oracle 12c Data Guard Deep Dive PresentationNabil Nawaz
Oracle Data Guard Deep Dive
Ensuring your business continuity for critical production databases is of paramount importance. Oracle Data Guard offers high available synchronization and reporting of your primary database. Oracle Data Guard is the most comprehensive solution available to eliminate single points of failure for mission critical Oracle Databases. It prevents data loss and downtime in the simplest and most economical manner by maintaining a synchronized physical replica of a production database at a remote location. If the production database is unavailable for any reason, client connections can quickly, and in some configurations transparently, fail-over to the synchronized replica to restore service. We will go through explaining Data Guard concepts, several new features in 12c such as Far/Fast sync, learn about Data Guard single instance and RAC setup step-by-step, configuration, broker setup and monitoring. This presentation will be very useful for someone who wants to take a deep dive into Data Guard or even refresh their skills.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

oracle platform provided by Sun
Micro system ( Now JAVA is oracle prod).
• Oracle for Linux.
• PWR Builder introduce by oracle used for data ware
housing competitor for ETL sys. By Informetica.
• Cognos powerful tool as Infor. Used for data ware
housing.
• ERWIN strong competitor to Oracle designer.
• IDE as VB & .NET called SQL developer & J Dev.
• Mysql, Teradata, sybase, DB1,DB2, MS. Sql server.
• 3rd
Party tools as TODD by Quest Technology.

6. Data is Defined as
• A value for an attribute of an entity.
• Entity is Real World Thing which exist
and can be described in terms of one or
more attributes.
• Database is Organized value of all
SAME type of entity.
www.orienit.com
7. Memory of ORACLE( Data
Dict.)
Arrangement of system
table stores data about data
called as METADATA.
RDBMS discovered for non
procedural access.
www.orienit.com
9. Parameter File
This is the first file oracle read at start of
the database. Parameters are system
variables sets environment of system,
file also called as init.ora.
From Oracle 9i SPFILE is introduce and
this file is binary formatted and it is the
binary version of init.ora.
www.orienit.com
10. Control File
Its important file of Oracle Database and
if control file is lost it means no recovery
is possible also it is binary formatted.
Oracle multiplex the file and stored in 3
files same locations name as
control1.ctl, control2.ctl, control3.ctl.
www.orienit.com
11. 3 Important Numbers
• SCN : System Change Number.
It is assigned by oracle to every committed
transaction always increasing..
• LSN: Log Sequence Number.
The sequential number assign to redo log as
they get filled and recycled.
• CPC : Check Point Counter.
Its is also ever increasing number and to
every check point is assigned.
www.orienit.com
12. Logical Database
Structure Oracle uses logical database structure to store data
on physical operating system file.
DATA BLOCK : Is the foundation of oracle storage. It consist
of number of bytes of disk space in OS.
EXTENT : An extents is two or more contagious oracle data
blocks and a unit of space allocation.
SAGMENT : A segment is a set of extents allocated to logical
structure like table or oracle objects.
TABLESPACE : A table space is a set of one or more
data files consist of related Segments.
www.orienit.com
13. Schema
• Schema is set of objects own by User Account.
• Each schema has user account but each user
don’t need schema.
• A user account is account with database having
privileges to perform predefined activities on
data.
• Schema may not exist with user account but
user account is exist without schema.
• Purpose : Maintenance of object like backup &
recovery, implementation of security and access
level.
www.orienit.com
14. Redo Log File
Oracle used redo base recovery and allow to
recover only committed transaction till the point of
failure.
The redo base recovery in oracle is implemented
through the redo log file.
When system fails then oracle read history from
these redo log file and guaranties the recovery till
the point of failure.
These files are created at the creation of oracle db.
The files are reusable and used as round robin
passion.
Maximum size is 50Mb.

17. 3 Types of Buffer
Free Buffer : A buffer which is ready to take
new data.
Pinned Buffer : A buffer which have data
under use (not committed or not rollback.)
Dirty Buffer : A buffer which have data which
is committed called permanent.
www.orienit.com
18. LRU Algorithm
• List Recently Used : This algorithm is used to write data
from data buffer pool (dirty buffers) in to data files.
Data Buffer Pool: Divided into 3 sections.
Keep Buffer Pool : It holds the frequently requested data.
(Based on MRU).
Recycle Buffer Pool : The data which is not requested
immediately after used is loaded in recycle buffer pool
and eliminated after used.
Default Buffer Pool :The data which is not required in
above pools is loaded in this pool.
www.orienit.com
19. Redo Log Buffer
• The redo log buffer is the place where
data or entries are stored before writing
to redo log file.
• All entries are written in serially to redo
log file due to SCN.
• When user commits the data the data
written to redo log file.
• If not commit or rollback then 75% full
written to redo log file.
www.orienit.com
20. Shared Pool Area
• This is the most busy area of SGA.
• 3 stages of SQL.
• Parsing : It resolve the reference made to the
different object in SQL statement resolution of
privileges.
• Planning : After parsing the statement hand
over to Optimizer for drawing execution plan to
performing activities in SQL statement.
Optimizer breaking down the SQL statement
to get result.
• Execution : To get result and display as per
request.
