Patch and Provision in EM12c: #5 Provision a Real Application Cluster Database
As part of the Database Lifecycle Management (DBLM) Pack, Database Provisioning in Enterprise Manager is a powerful and quite flexible feature to provision databases. In the past, I have written several articles on Patching and Provisioning (P&P) using the #em12c and today I’d like to add one more to the list. This time, it is […]
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 […]
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 […]
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 🙂 Over the last couple of weeks, I spent a few hours across several sessions explaining and demonstrating a GoldenGate […]
Create a Standby Database using EM12c
I wanted to make this a quick post, because a friend was mentioning a slight problem during a manual set up of Data Guard. 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 […]
#em12c Metrics – Part 1: An Introduction
From the middle of 2013, I’d been busy in preparation for one of my presentations for IOUG’s Collaborate 14 Conference in Las Vegas. It is on Capacity Planning Enterprise Manager 12c’s Metrics (available on slideshare), one which I had the honor of presenting earlier at a Georgia Oracle User Group meeting in Atlanta, GA this […]
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. Coincidentally, that is where I had been liv. During a recent EM12c project at her company, we were […]
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 […]
Starting NFS quotas: Cannot register service: RPC: Unable to receive; errno = Connection refused
While trying to setup NFS on an OVM 3.2 configuration on OEL 5.9, I followed the documentation to the letter but when time came to start the NFS daemon I kept getting the error above. After a little googling, it turns out that RPCBind may not be running. [root@ovm /]# rpcinfo -p rpcinfo: can’t contact […]
Oracle VM 3.2 – OVMAPI_4004E Server Failed Command: HTTP server returned unexpected status: Unauthorized access attempt
You might receive the error message below while discovering an Oracle Virtual Server: This means that most likely your password for the agents user is incorrect. I got around this by resetting it on the Oracle Virtual Server. Thanks to Avi for posting it in the Oracle Forums! Attempt to rediscover again, and it should […]
