Turbocharge SQL Performance in PL/SQL with Bulk ProcessingSteven Feuerstein
Is your Oracle Database application running slower than you'd like? One of the first things to check is row-by-row processing: non-query DML (insert, update, delete) within a loop. And the fix? Bulk processing, either with smarter SQL or with FORALL and BULK COLLECT in PL/SQL.
Oracle Week 2015 presentation (Presented on November 15, 2015)
Agenda:
Aggregative and advanced grouping options
Analytic functions, ranking and pagination
Hierarchical and recursive queries
Oracle 12c new rows pattern matching feature
XML and JSON handling with SQL
Regular Expressions
SQLcl – a new replacement tool for SQL*Plus from Oracle
Oracle ACE Director Dan Morgan presented those slides about migrating to database 12c and how to get it right. For more information, visit www.perftuning.com
Between 2015 and 2017 a large percentage of Oracle's existing customer base will be upgrading their existing databases to the new version 12cR1. Most of the time when upgrades happen the only benefits organizations receive are the satisfaction of having survived the upgrade unscathed. In general, the new database, other than having a new version number, provides little in the way of tangible benefits.
With the re-architecture that can come with a 12cR1 upgrade it is, for the first time, possible to plan for and receive substantial measurable benefits, and possible to make costly mistakes that could create substantial liabilities that are both business and financial.
Oracle ACE Director and industry veteran Dan Morgan, in a presentation targeted to IT/IS management explores both the benefits and the risks and provide a guideline for "getting it right."
This Performance Tuning's Lunch & Learn event focuses on management, planning, and budgeting, not features and technology, and provides you and your management teams the information they need to perform the next database upgrade or migration cycle.

AskTom: How to Make and Test Your Application "Oracle RAC Ready"?Markus Michalewicz
Oracle Real Application Clusters (Oracle RAC) is the preferred availability and scalability solution for Oracle Databases, as most applications can benefit from its capabilities without making any changes. This mini session explains the secrets behind Oracle RAC’s horizontal scaling algorithm, Cache Fusion, and how you can test and ensure that your application is “Oracle RAC ready.”
This deck was first presented in OOW19 as an AskTom theater / mini session and will be presented as a full version in other conferences going forward at which time I will provide an updated version of the deck.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

5. A Cool Trick
Who never had a problem with a SQL that is killing your
Database Performance and you can’t fix it because it’s
running from an external closed application that you or
your developers can’t touch?
Since Oracle version 10 this is a problem of the past, now
you can easy solve this kind of problem using the
DBMS_ADVANCED_REWRITE package, which allow you to
transform/customize queries on the fly, changing for
example one query with bad explain plan for another one
with a good explain plan.
6. DBMS_ADVANCED_REWRITE
Before you become too excited, please remember the
following restrictions:
• It does not work with bind variables.(Alternative solution
at Metalink Doc ID. 392214.1)
• Only works for the SELECT statement.
• Does not work when the base table is modified through
DML.
7. Data Masking with Oracle
• Important to protect your sensible data in
Dev/QA/Test Environments
• Protect your data when sending it to outside
your company.
Normal Product s used for Data Masking?
OEM / Grid Control
Data Pump
http://www.oracle.com/technetwork/database/datapump11g2009-transform-133936.pdf
9. Data Repository and Version Control
As a DBA, I’m always looking for proactive ways to allow
me to be prepared in case of a disaster strike or if
an emergency release rollback is required (I love to use
always the “What if” methodology), and due to
these reasons, have a metadata repository and version
control of it is always useful .
10. Creating Smaller Copies of Production
That is a very common task for a DBA, you are always
having a task to create a copy of your Database
( for development or test purpose ) but your
destination server don’t have enough space to create
a full copy of it! This can be easily solved with Data
Pump, for this example, let say that you only have
space for 70% of your production database, now to
know how to proceed, we need to decide if the copy
will contain metadata only (no data/rows) or if it will
include the data also.
11. More Data Pump Stuff

12. More Data Pump Stuff
• Flashback Consistent Backups
By default expdp is consistent only for the table that
is currently being exported.
You can use: FLASHBACK_TIME or FLASHBACK_SN
Note: On 11g the CONSISTENT parameter was
deprecated , At 11g you can use the
FLASHBACK_TIME=systimestamp to get data pump
export to be consistent to a single point in time.
Since 11.2 you can also use the legacy mode option
to use the old parameter CONSISTENCY=y
14. PROGRAM
The Oracle ACE Program is designed to recognize and reward
members of the Oracle Technology and Applications communities
for their contributions to those communities. These individuals
are technically proficient (when applicable) and willingly share
their knowledge and experiences.
The program comprises two levels:
Director.
Oracle ACE and Oracle ACE
The former designation is Oracle's way of saying "thank you" to
community contributors for their efforts; we (and the community)
appreciate their enthusiasm. The latter designation is for
community enthusiasts who not only share their knowledge
(usually in extraordinary ways), but also want to increase their
community advocacy and work more proactively with Oracle to
find opportunities for the same. In this sense, Oracle ACE is
"backward looking" and Oracle ACE Director is "forward looking."
