VirtualBox, NAT, and Port Forwarding
At Bobby’s (@dbasolved) insistence, I decided to write this post because it might prove useful for some folks. He mentioned following a note by Jeff Smith (@thatjeffsmith) that he is unable to locate at this time. If you are a VirtualBox user, you obviously have a need to maintain multiple Virtual Machines. You would also need to setup a type for...
Metric Extensions in EM12c #1: Monitor a Useful Target such as a GoldenGate Instance
Back in August of 2013, I wrote a post on “Alternative Method to monitor GoldenGate from EM12c outside the GoldenGate 12.1.0.1.0 Plugin” and then back in December of 2013 I wrote another one a Metric Extension to Monitor Unsupported Database Versions. As it turns out, the first post has been quite useful in many customer sites but what it lacks is...

ggsci: error while loading shared libraries: libnnz11.so: wrong ELF class: ELFCLASS32
I know what some of you might be thinking, is this an Elf Class from Word of Warcraft? Not quite. Coincidentally, when you google imagines for “elf world of warcraft”, you get mostly female ones :)

I told him you could do it through EM, and then recalled that I had documented it a while back. After the tube light finally went on in my head, it occurred to me that this would a good post.
When leveraging EM to set up, monitor,...

opatch apply online on 11.2.0.4
The credit for the patch apply in the post goes to a new friend that wishes to remain anonymous, except that her initials start with KA, and who happens to work at a company in Memphis, TN.

Set oraInventory for EM12c Agents during GUI Installation
So, this is a peculiar problem that I had to dig to find a solution for; each time I deployed an agent to Add Targets to EM12c where no other Oracle Software was located, it would always created the oraInventory located under the $HOME directory. In my case, /home/oracle/oraInventory. This is quite annoying because for subsequent Oracle Software installs,...

GoldenGate 12.1.2.0 MBeansContainerImpl - Runtime exception starting jAgent Server
During the EM 12.1.0.3.0 configuration to monitor GoldenGate, I stepped through the documentation (as I have numerous times in the past) but this time I kept getting the error message in the jagent.log.
