About Course

Oracle DBA is a group of data that is handled as a whole. A database’s main function is to store and retrieve relevant data. The database server holds the key to resolving information management issues. In a multiuser scenario, a server often manages a lot of data reliably so that multiple users can access the same material at once. Delivering excellent performance while accomplishing all of this. Additionally, Oracle DBA server offers effective solutions for failure recovery and guards against unauthorized access. Enrol today to earn your certification.

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?

For the needs of business computing, Oracle’s grid design combines a sizable database server, memory, and connectivity to produce a tailored, as-needed computing resource. The grid computing architecture continuously assesses resource consumption and modifies supply as necessary.

A grid of various connected database servers, for instance, might be used to run multiple programmes simultaneously. The database administrator might automatically assign a dedicated server to that programme to handle the escalating demands if monthly reports are overdue.

Advanced workload management techniques used in grid computing allow programmes to collaborate across multiple servers. Resources within a region can be offered dynamically and data processing capacity can be increased or eliminated as needed. Web services make it possible to quickly integrate apps to launch 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.
