Every time an Oracle ® Database reads or writes data to a disk, the database generates disk input and output (I/O) operations. The performance of many software applications is limited by disk I/O, and applications that spend the majority of central processing unit (CPU) time waiting for I/O activity to complete are I/O bound. I/O calibration helps to address this issue.
Parallel Replicat is one of the new features introduced in Oracle ® GoldenGate 12c Release 3 (184.108.40.206). Parallel Replicat is designed to help users to quickly load data into their environments by using multiple parallel mappers and threads.
This blog discusses the Oracle Exadata Smart Flash Cache feature and its architecture, including the write-back flash cache feature.
In an Oracle Real Application Clusters (RAC) environment, all the instances or servers communicate with each other using high-speed interconnects on the private network. If the instance members in a RAC fail to ping or to connect to one other via this private interconnect, all the servers that are physically up and running (and the database instances on those servers) might end up in a condition known as split-brain.
The traditional supply-chain management processes with on-site IT applications are rapidly moving to the modern supply-chain cloud infrastructure. This blog covers the characteristics and benefits of the modern supply chain management in detail.
In our previous article, we dove deeply into the Live Migration process by looking at how Conductor passes data back and forth between Scheduler and the Source and Destination Compute Nodes. We have found a host machine at this point and verified that all of our preliminary checks will pass.
In our previous article, we began to trace the process of a live migration and explored how Nova API receives this call, processes it, injects basic information about the instance and eventually passes it to our next destination, Conductor. Before we continue the discussion, let's again review our assumptions.
The OpenStack live migration process is one of the most vital processes in the compute drivers, but it is also easily one of the most complex. This complexity drove my curiosity to better understand what is happening under the hood, and I wanted to share that knowledge with you. In this article, we dive deep into the OpenStack codebase, but first, the article does assume a few things.
It has been a while since the last official release of Syntribos - a whole year, in fact! But we haven't been sitting idle. This article explores the new capabilities offered by this latest release.
In my previous series of articles on OpenStack networking, I mentioned that there are ways of doing things in the virtual world that can’t be done in the physical world. Because of that, we shouldn’t let the physical server limitations control our thinking in the virtual world -- but often we do.
