Oracle   1z0-593 examen   certification 1z0-593   1z0-593 examen
Explanation:
Incorrect: Oracle Cluster Health Monitoris designed to detect and analyze operating system (OS) and
cluster resource related degradation and failures in order to bring more explanatory power to many
issues that occur in clusters where Oracle Clusterware and Oracle RAC are running such as node
eviction. It continuously tracks the OS resource consumption at each node, process, and device level.
It collects and analyzes this cluster-wide data. In real time mode, when thresholds are hit, an alert is
shown to the operator. For root cause analysis, historical data can be replayed to understand what
was happening at the time of failure.

NO.8 You are creating an Oracle Cluster database using DBCA. The "Memory size (SGA and PGA)"
field is supplied on value of 2000 MB. The default Block used for the database is __________.
A. 2 KB
B. 4 KB
C. 8 KB
D. 16 KB
E. 32 KB
Answer: C

Oracle   certification 1z0-593   1z0-593 examen   certification 1z0-593   1z0-593
Explanation:
Note: *In the Block Size list, enter the size in bytes or accept the default. Oracle Database data is
stored in these blocks. One data block corresponds to a specific number of bytes of physical space
on disk. While using pre-defined templates, this field is not enabled since the database will be
created with the default block size of 8 KB. But while using the custom option, you can change block
size. Selecting a block size other than the default 8 KB value requires advanced knowledge and
should only be done when absolutely required.
