Parallel Streams, CompletableFuture, and All That: Concurrency in Java 8
 
48:06
Kenneth Kousen, President, Kousen IT, Inc. The Java 8 (and 9) standard library includes multiple techniques for taking advantage of parallelism and concurrency, including parallel streams and the CompletableFuture class. Combined with the ExecutorService and other classes from java.util.concurrent, they give developers a wide range of choices for optimizing program speed. This session reviews the options and trade-offs involved.

Demonstrating Oracle DB Elapsed Time and Wall Time With Parallel Query
 
03:37
Is it really true? In my recent postings I wrote that when using parallel query a SQL statement's wall time is roughly equal to its elapsed time divided by the number of parallel query slaves. To check I ran an experiment and posted the results. The results are both obvious and illuminating. If you don't want to read but just sit on the couch and watch a video, you're in luck! I created a special video clip demonstrating what I wrote about. The main video clip is from my OraPub Online Institute video seminar, Tuning Oracle Using An AWR Report - Part 1. (NOT Part 2 as the video shows) From my blog posting: http://blog.orapub.com/20140907/watch-oracle-database-elapsed-time-and-wall-time-with-parallel-query.html For more information on OraPub r for more great education, go to www.orapub.com

Jump-Starting Lambda Programming
 
57:58
"You've probably heard about the new Lambda feature that's going to be in Java 8. What might not be obvious is why Lambda is important and how you can use it effectively. This session re-examines familiar programming constructs, taking apart several simple examples and putting them together in a new, "Lambda-ready" (functional) style. It also shows how this powerful alternative style provides greater flexibility for structuring programs and easing the transition into parallel programming. Finally, it introduces Lambda itself, which is when it will become clear why the Lambda construct is important and how effective it can be when used in this style. There will be no math in this session. Well, maybe just a little. Copyright © 2013 Oracle and/or its affiliates. Oracle® is a registered trademark of Oracle and/or its affiliates.

Oracle DB Vs MySQL for Enterprise DataBase Deployments
 
08:54
Oracle DB is big, and expensive, but it brings a lot to the "table" when compared with MySQL. MySQL has limited ability to audit. MySQL's security is unsophisticated. There are no groups or roles, no ability to deny a privilege (you can only grant privileges). A user who logs in with the same username and password from different network addresses may be treated as a completely separate user. There is no built-in encryption comparable to Oracle. MySQL's Authentication is built-in. There is no LDAP, Active Directory, or other external authentication capability. MySQL has no MPP (massively parallel processing ) support. Unlike Oracle MySQL has no fractional-second storage type for times, dates, or intervals. There is no RAC (Real Application Cluster) support in My SQL, and no failover or server promotion either. These are strong features in Oracle MySQL's number of joins per query is limited to 61. Oracle's limit is much larger. MySQL Replication is asynchronous and has many limitations and edge cases. For example, it is single-threaded, so a powerful slave can find it hard to replicate fast enough to keep up with a less powerful master.

Analysing Parallel Execution Skew - Using Diagnostics / Tuning Pack license
 
01:20:37
In this final part of the tutorial I show how to analyse Parallel Execution Skew if you happen to have a Diagnostics / Tuning Pack license. Having such a license can be very helpful for doing such an analysis, however the tools provided by Oracle still do have some shortcomings and bugs. These are demonstrated and finally I show how to perform such an analysis using my XPLAN_ASH utility that offers functionality not available out of the box from Oracle.

This session explores GraalVM and its uses for typical Java applications: getting the best peak performance on various workloads, creating native images for instant startup, mixing JavaScript and Python, or Ruby, or R into your code. You'll learn how to understand what the JIT compiler is doing with your code, how to collect the necessary debug information for further profiling, what are the limitations of GraalVM's native images and how to overcome most frequent of them. We'll look at the polyglot applications and how they impact the code you're writing, learn the polyglot API you need to use to effectively mix different programming languages in one program. We'll explore using the common tooling like VisualVM and Chrome debugger for languages supported by GraalVM, even when you're running JavaScript as stored procedures in the database. The session is based on a series of demos you can follow along and try yourself later, and the insight you can directly use.

In-Database Hadoop: When MapReduce Meets the RDBMS
 
57:00
"The MapReduce programming model enables developers without experience with parallel or distributed systems to use the resources of a large system and process big data. Apache Hadoop implements the MapReduce model. The combination of the RDBMS and MapReduce is being researched. This session describes a prototype of a Hadoop implementation that enables you to reuse native mappers and reducers applications written in Java, directly in the database. Leveraging Java VM in the database is what makes this prototype possible. The major benefits of this implementation: source compatibility with Hadoop, minimal dependency on the Apache Hadoop infrastructure, seamless integration of MapReduce functionality into SQL, and better parallelism and efficiency.

Held on September 20 2018 Watch Joel Kallman, Senior Director of Software Development, along with a number of experts from the global APEX Community, to discuss Oracle Forms Modernization. Learn about the positive aspects, together with the challenges, of using Oracle APEX to modernize your Oracle Forms applications. Real-world success stories, challenges, and tips are presented. Session Chats: https://apex.oracle.com/pls/apex/f?p=20051:4:1757390683715::NO::P4_ASKTOM_OFFICE_HOUR_ID:157276294837434079139335725983223048710 Key Video Timestamps: Panel Introduction [9:15] Question 1 [11:55] - Can you please give a brief overview of one of your completed projects (or something which is underway)? Question 2 [20:50] - What would you say is your approach in modernization with APEX? Rewrite? Partial migration? Create new apps adjacent to the existing Oracle Forms apps? Question 3 [29:40] - What were some of the biggest challenges you faced in this type of project? Question 4 [36:15] - What was the biggest benefit to the customer? Has the customer been satisfied with the result? Question 5 [41:50] - We always talk about preserving your investment in the back-end business logic, in SQL and PL/SQL. Is this a fallacy? How much of the back-end code had to be modified to work in the new world with APEX? Question 6 [46:30] - Can you describe the process you follow to assess if something is appropriate to be modernized with APEX? Can you give an example of something you would not use APEX to modernize a Forms app? Question 7 [50:55] - How do you go about educating someone to use APEX, who comes from a Forms background? It is Web, and Web is different. Question 8 [1:01:45] - How long does it take for the existing Forms developers to become competent in APEX and Web development? Were they able to carry on with further development on their own? Question 9 [1:04:35] - Can customers do this migration on their own? This Office Hours forum is comprised of our many partners, and if I were watching this, I might think “wow, I need outside help to get this done”. What would you say? Question 10 [1:08:40] - For anyone watching this, who is contemplating modernizing some fo their Forms apps with APEX, do you have any specific advice? AskTOM Office Hours offers free, monthly training and tips on how to make the most of Oracle Database, from Oracle product managers, developers and evangelists. https://asktom.oracle.com/ Oracle Developers portal: https://developer.oracle.com/ Sign up for an Oracle Cloud trial: https://cloud.oracle.com/en_US/tryit music: bensound.com

Parallel Universe: Java Developer’s Guide to Front-End Development
 
47:38
Kito Mann, Principal Consultant, Virtua, Inc. You’ve been comfortable building back-end services in Java or using a Java web framework, but now you must build an application with a JavaScript framework such as Angular, React, Polymer, Ember, Backbone, or a homegrown mismatch of jQuery and custom code. Suddenly you have entered a parallel universe with foreign terms such as “bower,” “node,” “npm,” “webpack,” “AMD,” “CommonJS,” “ES6,” “ES2015,” “TypeScript,” “Babel,” “gulp,” “grunt,” “shim,” and “polyfill,” to name a few. What do they all mean, and how are they related to each other? More importantly, how do they compare to what we know and love in the Java universe? Attend this session to explore another universe.

Orion Council July 8 2018
 
24:28
Answering your questions: What exactly is the 5th dimension? Do parallel lives on other planets help us in our personal ascension? Can members of our soul group (achieving ascension) exist in the other dimensions? Hello Orion Council, do we have personal power spots and how do we find out where those are? Should we be grounding just now everyone talks of grounding the energies but each time i do i start to feel crap unless im working around energy lines or sacred sights i seem to want to ground the energy What is the reason why we get cavities and other teeth issues even when we practice good dental hygiene? Is there a meta-physical/mental/emotional connection other than what our dentists typically tell us? I would like to know more about Orion starseeds in general through Orion Council and if there is any significance for them during the dates of Dec 7-20 and June 7-20 when Orion is conjunct with the sun How do I let go of fear of upleveling, thus self-sabotaging? How do you recommend we manifest physical healing at this time? how do we ride the waves of ascension, loving and accepting all spectrums of human emotion, without getting lost in the wave? what does the council say about shifting focus/intention of perception & how to properly do this? Can the Orion Council speak upon why and how all of sudden many of us are just fluently remembering what is termed light language? Hello Orion council, ive often heard cleanliness is next to godliness. What is it about those that experience higher dimensions, that makes them disregard cleanliness of themselves or their surroundings? Is there any detriment to be had with tolerance of dirt? Are the symbols in your Book actually Multi-dimensional? And, can they be quantified with mathematical formulas? My question is when you get negative individuals verbally attack you for no reason just to bring you down or get a reaction out of you, what is the best response? Can one use certain crystals to aid physical body turn New silica electric style? If yes, which and how? / What is benefiting to know about the Moscow stargate? -- ☮Official Website [blog & more]: http://www.kristaraisa.com ☮AMAZON BOOKS [paperback & Kindle]: http://amazon.com/author/kristaraisa ☮SHOP [Galactivate ormus; Oracle cards, Art]: http://kristasangels.etsy.com ☮Online Courses: https://kristasangels.teachable.com/ ☮InstantGo [Text Message Readings]: https://www.instantgo.com/kristaraisa ☮Spiritual AUDIO: https://apple.co/2BVTe9R ☮RAP: https://itunes.apple.com/us/artist/ezoterra/1328955491 & http://www.soundcloud.com/ezoterra (also see “Ezoterra” on Spotify) ☮PINTEREST: http://www.pinterest.com/psychicfairy ☮INSTAGRAM: http://www.instagram.com/galacticfaery ☮DEPOP: http://www.depop.com/kristasangels Krista Raisa 2370 W.STR.89A Suite 11-138 Sedona, A.Z. 86336 U.S.A.

DistributableStream: A Java 8 Stream Computational Model for Big Data Processing
 
56:57
With lambda expressions and the Stream API, Java 8 becomes a highly powerful and expressive programming language that supports queries on in-memory data collections. These new Java features have shed light on a Stream computational model that enables users to easily process big data across multiple computational platforms. This session describes DistributableStream, the Java abstraction that supports distributed and federated query. DistributableStream builds on Stream, supporting execution of generic queries on any registered compute engine. At execution time, each portion of a DistributableStream is assembled as a local stream that represents data partitions locally stored on each machine.

Oracle Data Pump
 
11:52
Oracle Data pump utility enables very fast bulk data and metadata movement between Oracle databases. It provides parallel Export and Import utilities (expdp and impdp) and Web-based Oracle Enterprise Manager Interface. 1. Data Pump Export and Import utilities are typically much faster than the original Export and Import Utilities. A single thread of Data Pump Export is about twice as fast as original Export, while Data Pump Import is 15-45 times fast than original Import. 2. Data Pump jobs can be restarted without loss of data, whether or not the stoppage was voluntary or involuntary. 3. Data Pump jobs support fine-grained object selection. Virtually any type of object can be included or excluded in a Data Pump job. 4. Data Pump supports the ability to load one instance directly from another (network import) and unload a remote instance (network export).
