Overview of Oracle Data Guard Training:

Oracle Data Guard Training enabled network monitoring from the primary database server. In Oracle Data Guard Training, OEL is the primary database server hostname, and OEL standby is standby database server name. Using a backup copy of the primary database, you can create from one to 30 standby databases. The arrow marks mean the packets which are being transferred from primary to standby is what this arrow mark. All Data Guard standby databases can enable up-to-date read access to the standby database while redo being received from the primary database is applied. If you the amount of data which is being transferred for every second because this will keep refreshing for every two seconds and the content are basically being transferred from your primary to standby. The standby databases, together with the primary database, make up a data guard configuration. Vice-versa if you want to the contents which are shipping from your standby two primary back.

What is Oracle Data Guard?

The product which Oracle company markets as Oracle data guard forms an extension to the Oracle RDBMS. Oracle Data Guard Training Aids in building up and keeping up optional standby databases which fill in as elective stores to generation databases call essential databases. Oracle Data Guard gives both Graphical user interface and command-line tools for managing data card configurations. The Data card supports both physical immediate deployment and logical sites. The Oracle corporate makes data guard available only as a bundled feature included within its enterprise edition of Oracle RDBMS.

data guard online trainingWith appropriately set up data operations DBMS can facilitate fill overs or switch covers two alternative hosts in the same or alternative locations. For the purpose of data guard, each Oracle database works either in an essential database part or in a remain by database part. The databases could be changed from one part to the next. The tech could be executed in one of the following configurations:

  • Physical Stand-by
  • Logical Stand-by
  • Active Data Guard

The database in Data Guard Training:

Basically, Oracle Data Guard Training is to implement high availability of the database. The database is about control files, redo log files, and data files. The control files and redo log files can be protected by multiplexing and database files can be replicated to a different location using data guard. The entire database is available in a different location. Generally, data guard is implemented across the sides, unlike real application clusters. The rack is implemented within the site to protect the instance failures. The Oracle Data Guard Training sites through the primary database are down still the secondary database is available can make it available. There are changes between 10g and 11g in setting up data guard the options that have like the major one is active data on our active standby.

Active Standby:

Oracle Data Guard Training will have the network set up between two locations which are at the high bandwidth and low latency. The main component for data guard is the network after having the setup. The network plays a critical role in transmitting the data from primary to secondary. Oracle Data Guard Training depends upon the type of protection mode.

Protection Modes:

The Protection Modes are supported in setting up data guard. There are

  • Max performance
  • Max protection
  • Max Availability
Max performance:

The moment set up data guard by default the protection mode is under max performance. When the database is set up in max performance is purely working based on the arc elephant files. And when arc log file is generated on production that will get shipped to the standby. As the standby database is in MRM mode which is managed recovery mode as and when the arc log file shipped from primary site to secondary site. This particular arc log file will get applied to the standby database. Oracle Data Guard Training is a default setup. In case there can be a data loss when loss of redo files on the production environment.

Max protection:

Oracle Data Guard online Training

The transactions that are there in the redo log files not made it to arc log file. It can implement max protection and protection mode can be shifted to max production. Once you make commit as we know the commit will make sure the data will be written to the redo log files. If production goes down for some reason still transaction is saved on to the standby for that need to make sure. Oracle Data Guard Training has standby redo log files also without standby log files cannot shift the protection mode from max performance to max production.

Max Availability:

It gives the high priority to the transactions are compromising on the availability on the production. In the case of max production both production and standby must be available. You must have created standby the log files in case of max production and whatever content is there in the redo log files of the production must be available in the standby log files also. Max available is like max protection. in case the standby is not available production can continue. Oracle Data Guard Training is basically redone log files and both needs standby, redo.

Creating Physical Standby Database:

To create Oracle physical standby database will have the following two server stages:

  • Primary Database
  • Standby Database

In both databases are using the file system as derived storage. in the primary database, our server IP is the driver’s name is Oracle unique. Our production server is archive log mode if not have to convert it to not go out of log mode. It is in no archive log mode so you will have to convert it to archive log mode. The auto body archive is enabled that will log more is an archived blog. It has to configure the system in the primary there is first as a few the revisions will have to change. In the primary database are creating can by log files. You are creating the physical standby database all these log files will be copied automatically to the territory.

Data Guard Broker:

The Data Guard Broker is a distributed administration structure that computerizes and brings together the creating, support and observing of Data Guard configurations. It will arrange data guard the broker and will show how to change over to that generator.You will a ship that role from primary to standby and standby to the primary database. Oracle Data Guard Training can access the database regard broker with Enterprise Manager and also by DGMGRL command line interface. The Demonstrate some of the operations through the DGMGRL command-line interface. This is the system parameter can set DG broker to start equal to true and you can invoke the BGMGRL command from any of the databases, and the server.

Create Configuration:

DGMGRL>create configuration ‘DGCinfig1’ as the primary database is ‘orcl‘ connect identifier is orcl;Add database into Broker configuration:

DGMGRL> add database ‘sbyorcl‘ as connect identifier is sbyorcl;

Oracle Data Guard Training will add this again standby database and then will failover. It has configured our network for data card broker. The database is the global database service orcl_DGMGRL and SID is orcl. This is the change all have to do and the change you have done in it is in the primary database.

Real-time apply Dataguard:

The roles of these databases before you go ahead and just select database_role from reading all order a database. This is acting like physical standby let the same thing on the next one is a primary database. The people know on the physical standby database will not be able to use real-time apply or not first on the physical standby side for the current media recovery. The standby side you will have to write a query like select distance core ID comma recovery underscore more from v dollar archive underscore dest underscore status where destination underscore ID is equal to 1.

select dest_id, recovery_more from v$archive_dest_status where dest_id=1;

This is the first destination, you can it managed recovery but not real-time apply. To show you the difference that as soon as you do modifications on the primary side it will be applying to the standby side. It has to real-time apply else you will not be able to see the changes as soon as a first thing is it will have to enable real-time apply else this feature will not be enabled. Oracle Data Guard Training is proving to have the database in the open state but in read-only mode. That is called an active standby database will have to convert the physical standby database into the active standby database. Manage the real-time apply that means your recovery mode is using real-time apply. You will have to understand if your database is open in read-only mode definitely here you can that but that in terms of output of a query.

select database_role from v$database;

This is select database underscore role from v dollar database which will not give you any difference it is physical standby only it will not active standby to that will have to query.
