COMPLETE DETAILED CORRECT
ANSWERS
A copy of a redo log file before it is overwritten by new redo information. - answer ✔✔-
Archived redo log file
is the archiver process that copies the content of redo logs to archive redo log files. The archiver
process can have multiple processes, which allow the archiver to write to various destinations
such as D: drive, E drive or other storage. - answer ✔✔-ARCn
Refers to the data that is sampled at specified intervals from the current state of all active
sessions. - answer ✔✔-ASH (Active Session History)
Designed to relieve the burden of disk and storage management and relies on Oracle to
maintain the database storage. - answer ✔✔-ASM (Automatic Storage Management) storage
A script that performs the upgrade in parallel, making use of the CPU resources available. -
answer ✔✔-catctl.pl
is the checkpoint process. In Oracle, data that is on disk is called block and the data which in
memory is called buffer. When a block is written to the buffer and changed, the buffer becomes
dirty, and it needs to be written down to the disk. This process updates the control and data file
headers with checkpoint information and signals writing of dirty buffers to disk. Note that
Oracle 12c allows both full and incremental checkpoints. - answer ✔✔-CKPT
, Used to group user sessions together so that the different groups can be assigned different
processing requirements. - answer ✔✔-Consumer groups
Contain locations of other physical files, database name, database block size, database
character set, and recovery information. These files are required to open the database. - answer
✔✔-Control files
corresponds to a number of bytes on the disk. Oracle stores data in these. These are also
referred to as logical blocks, Oracle blocks or pages. - answer ✔✔-Data Block
Provide information about the database and its objects. - answer ✔✔-Data dictionary views
Physical files that actually store the data that has been inserted into each table in the database.
- answer ✔✔-Data files
A high-speed mechanism for transferring data or metadata from one database to another or
from operating-system files. - answer ✔✔-Data Pump
An area in SGA that caches the database data, holding blocks from the data files that have been
accessed recently. - answer ✔✔-Database buffer cache
The most powerful role in the database. This role has all the system privileges and several
administrative privileges. - answer ✔✔-DBA
A Java-based tool that is used to create Oracle databases. - answer ✔✔-DBCA (Database
Configuration Assistant)
