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
Networks
Default Network Configuration for Oracle VM Servers
After you reimage an Exalogic compute node from Oracle
Linux to Oracle VM Server, each compute node (dom0) has the following network
configuration:
-> Bonded bond0 interface over the eth0 interface.
-> Xen bridge interface, xenbr0, on top of bond0. The xenbr0 interface holds the eth interface
IP.
-> Bonded bond1 interface over ib0 and ib2
interfaces. This is the IPoIB interface
for the default InfiniBand partition.
Network
Configuration Performed by the ECU
Network configuration performed by the
Exalogic Configuration Utility (ECU), when it configures the Exalogic
machine. You must not modify the system
network partitions set by ECU.
