Oracle Architecture
 
04:11
This video describes the best architecture of the oracle after trying more than times to Oracle structure I decided to produce an animated video let's start first with the database structure on the left side you have the client here on the right side you have to serve a two-year the server side is divided in three main structures to memory the logical structure and the physical structure so let's use SQL Plus application to provide you every step up a transaction will be using Scott sample schema it is important to note that the whole string is an alias and not a database name district will be compared to this alias inside of a file called pianist named doc or this file is similar to a DNS and with up pain all the necessary detail to reach a database server locally a user process will be allocated and will validate the connection through a listener the listener will be in charge to allocate a server process the user processes da link to the server process let's now execute our first transaction for this example we will execute an update first to state that will be validated we call this step the parsing this server process sense back to confirmation of the parsing that statement with be written into their share pool and the redo log buffer an execution plan will also be created it to the fair share Paul that database book they choose fought the transaction will be read and copy into the database buffer cache only that feel implicated in that transaction will be held it to a - segment till the transaction is completed we call those copies the before image a copy of this block will be duplicated with the updated feel this copy is called me after image a confirmation will be sent to to use a process the commit statement will complete the transaction and will be written into to redo log buffer to commit statement triggers the log writer process and we'll send all statement for the current transaction into the redo log file the before image into undo segment could be then deleted went that threshold up to undo retention parameters reach alaskan from Asian will be sent to the user process went to current law kiss Paul it generates a switch lock triggering at the same time the archiver process and to log sequence number the archiver will generate and archive the file with the content of the current loc a switch up with them trigger a checkpoint process that will incriminate the checkpoint number by applying this last number into each data file header the checkpoint process with finally trigger the database writer process enright the last image from that database buffer cache into thirty people

How To Go From The OS To V$ With Oracle Processes - Introduction
 
05:29
While it is fundamental to Oracle performance analysis, even Senior Oracle DBAs forget Oracle core process architecture along with how to jump from an operating system Oracle process view into the Oracle V$ world. And of course, the reverse. So, in this webinar, after a short process architecture teaching and with only a couple key SQL scripts and basic OS tools, I'm going to be working in both the operating system world and the Oracle world as we see Oracle processes from two different perspectives. For information on how you can watch the full webinar, go to www.orapub.com/webinars Founder and Oracle ACE Director, Craig Shallahamer, is a long time Oracle DBA who specializes in Oracle performance. He is a performance researcher and blogger, consultant, conference speaker, and a teacher to Oracle professionals.

Oracle Database LGWR Three Second Rule. Really?
 
03:12
Go to the blog posting: http://blog.orapub.com/20140608/The-Oracle-Database-LGWR-Three-Second-Rule-Really.html I have learned the part of Oracle Database performance tuning is checking if what you have been taught is actually true. What I'm writing about today has been done before in Oracle Database 10g and 11g, but I wanted to document this using 12c. When I was first learning about the Oracle Database process architecture, the instructor said there are a number of reasons the log writer (LGWR) background process will wake up and do "something." In addition to this, if the LGWR was not signaled to wake up, every three seconds it would wake up by itself and check if there was something it needed to do. Is this "three second rule" really true? That's what this posting is all about.

How Oracle Instance Recovery Works
 
09:11
https://dbagenesis.com/ DBA Genesis provides all you need to build and manage effective Oracle technology learning. We designed DBA Genesis as a simple to use yet powerful online Oracle learning system for students. Each of our courses is taught by an expert instructor, and every course is available on demand. Oracle instance recovery is an advanced concept, but its interesting to know and understand it. Oracle performs instance recovery when the database is restarted due to instance failure or shutdown the database with ABORT option(shutdown abort) or startup the database with FORCE option(startup force). Instance recovery is taken care by SMON oracle background process automatically. Instance recovery consists of two steps. One is Roll forward, next is Roll backward.

Introduction to Oracle Listener
 
16:41
https://dbagenesis.com/p/oracle-11g-advanced-dba DBA Genesis provides all you need to build and manage effective Oracle technology learning. We designed DBA Genesis as a simple to use yet powerful online Oracle learning system for students. Each of our courses is taught by an expert instructor, and every course is available on demand. A listener is a separate process than your database processes which runs on the database server to accept incoming connections. Any client connection first lands on to database listener and then its handed over to the PMON process. All the databases running on a server must have their services registered with the listener or else listener will not be able to accept the incoming connections.

Deep Dive sessions from Oracle Guru "Arup" on DB Security , Indexes and Buffer cache in Cloud
 
01:29
#sangam18 #aioug #oracle Sangam18 At A Glance Sangam, the largest independent Oracle user’s group conference will feature over 150+ in-depth technical sessions presented by expert speakers from inside and outside of Oracle. Over 1000+ database administrators, developers and architects professionals are expected at the conference from December 7th-8th 2018 at The Oterra, Bengaluru.

He speaks frequently, has authored about 300 articles, co-authored 5 books, blogs at arup.blogspot.com and mentors new and seasoned DBAs. Sessions Database Security in a Single Day in the Cloud This session attendees will learn some simple but highly effective steps they can implement in just one day that will eliminate a lot of vulnerability and make the database secure against 90% of the common attacks. Should I Drop Indexes in Exadata Cloud In this session you will learn what storage indexes are in Exadata, how they work (and don’t), how they work along with traditional indexes, how to gradually evaluate the effect of indexes instead of a sudden change, how to compensate for lack of indexes and read execution plans. In this session you will learn how the blocks get into the buffer cache, what buffer cache chains are, how they are managed, how cache buffer chain latches are used and when they cause significant performance issue, how DBWR and checkpoint processes work, what causes the buffers to be written back to the disk, the role of commits and rollbacks in buffer movement between buffer cache and disks and much more.
