Dear Readers,
My name is Franz Devantier, creator of this blog. I am an Oracle Certified
Professional (OCP DBA 11g) Security DBA.
I will be sharing with you the basic duties of an Oracle DBA, and also
some of the undocumented, and not so well known tasks.
I will make a deal with you: If you refer me to a company that needs
database support, from a few hours per week to full time, and I am able to sign
a contract with them.
Then I will give you 10% of the monthly
contract or deal price every month. When
the contract ends, and we re-sign the contract, I will again give you 10% of
the monthly contract price. This will go
on until the company no longer employs or contracts me or my agents to look
after their databases.
I can do this, because that 10% is my
marketing budget. When we re-sign the
contract, in the future, it may depend on you giving the thumbs up again, and
that is worth 10% of the monthly contract price, to be given to you as
commission.
Exalogic
Managing Machine - Part 2
Viewing System Summary, Membership Graph, and Status
Ok, so you have clicked on the Dashboard tab on the center
pane, and you can see the following information about your Exalogic machine.
-> System Summary
-> Membership Graph
-> System Status
System
Summary Section
The
summary section is also the top section, or at the top of the page. You will see the name of the Exalogic
machine. Also in this section you will
see the description of name of the system identifier. The number of racks that are part of the
system. On the right hand side is a
summary of the number of unassigned incidents.
There are three unassigned incident icons which represent: Critical
incidents(Red), Warning incidents(Amber), and information incidents(Blue). These incidents originate from all the assets
that belong to the Exalogic racks.
Membership
Graph Section
The
membership graph section or the middle section displays the Exalogic system as
a hierarchy of its components. It shows
the relationship between the Oracle Virtual Machine (OVM) Manager, the physical
InfiniBand fabric, and the hardware that is stored in the rack. InfiniBand is a switched fabric
communications link that is used in high performance computing and enterprise
data centers, and also in the Exalogic Elastic Cloud System. You can navigate to any asset by double
clicking on the asset in the membership graph.
With
the controls on the top right of the graph pane, you can change the view of the
graph to either a horizontal or a vertical orientation. You can refresh the view by clicking on the
refresh Icon for the web page. There is
also a control to change the depth of the graph or the size of the images, ie
either bigger or smaller.
System
Status Section
The
bottom section or pane is the System Status Section. Here is a display of the total unassigned
incidents in chart format on the left hand side. On the right hand side is a listing of the
recent incidents encountered by the Exalogic system. This is listed in table format, with the
following columns:
->Severity: The severity column displays the severity of
the incident, with Blue, amber, and red icons.
->
State: This column displays the state of
the incident.
->
ID: This column displays the incident ID, for example ‘13003’.
