About Course

Oracle DBA is a collection of data treated as a unit. The purpose of a database is to store and retrieve related information. The database server is the key to solving the problems of information management. In general, a server reliably manages a large amount of data in a multiuser environment so that many users can concurrently access the same data. All this is accomplished while delivering high performance. A database server also prevents unauthorized access and provides efficient solutions for failure recovery.

Oracle DBA Online Training FAQ'S

What constitutes an Oracle Instance?

  • The SGA is a distributed memory that several programs can use. This section contains data that the instance needs to function.
  • System Global Area (SGA), a distributed memory space on RAM, and applications running make up an instance.
  • The running processes are OS processes, and every program in the instance has a specific role to play.
  • When an instance is "started," it creates the GAS and runs processes

What is the distinction between a data block, an extent, and a segment?

  • A data block is a database object's basic logical storage unit. As objects expand in size, they require extra storage in the form of continuous data blocks.
  • Extents are collections of consecutive data chunks.

What is the Oracle Grid Architecture?

Oracle's grid design combines a huge database server, memory, and connections to create a customized, as per requirement computing resource for business computing demands. The grid computing architecture constantly evaluates the consumption of resources and changes supply accordingly.

You might, for example, run several programs on a grid of numerous connected database servers. If monthly reports are pending, the database administrator might automatically supply a dedicated server to that program to manage the growing demands.

Grid computing employs advanced workload management, enabling programs to work cooperatively across several servers. As per requirement data processing ability may be added or deleted, and resources within a region can be provided flexibly. Web services enable the rapid integration of apps to establish a business.

What is the definition of normalization? What do the various types of normalization entail?

It is the process of structuring a relational database's fields and tables to reduce complexity and dependence. It guarantees that our data is consistent by saving the memory.

  1. First normal form - Only single (atomic) valued attributes or columns should be used. A column's values must all belong to a certain domain.
  2. Second normal form - It must be written in First Normal. It should also not be partially dependent.
  3. Third normal form - It's in the shape of the Second Normal. It also lacks transitive dependencies.
  4. Boyce and Codd Normal Form - Boyce and Codd is a more advanced variation of the Third Normal Form. This form is used to deal with anomalies that aren't addressed by 3NF. BCNF refers to a 3NF table that does not contain several identical candidate keys

Why Are Bind Variables Important?

Bind variables are crucial because most database suppliers provide an execution plan cache, which stores recently processed SQL statements and planning processes for again use.

Not recommended as there will be no server access working to do practical after training. Also there will be no fix for the same. So it's wastage of money. If server access not at all working then no meaning to provide server access. Also it not working for single day properly. Need to followup daily but in response you told will fix that sir at home once he will back will fix. After he came back again it's not working and not able to fix for single day also Every time new excuse it's wastage of money.

I have undergone Oracle Tuning training. I can proudly say that this is one of the best training institutes available in the market. The way Mr. Kumar teaches the concepts and makes them understandable is very commendable and unique. Even a novice can clearly understand the concepts clearly after attending his classes.
