Why is Virtualization Creating Storage Sprawl? By Storage Switzerland
Desktop and server virtualization have brought many benefits to the data center. These two initiatives have allowed IT to respond quickly to the needs of the organization while driving down IT costs, physical footprint requirements and energy demands. But there is one area of the data center that has actually increased in cost since virtualization started to make its way into production… storage. Because of virtualization, more data centers need "ash to meet the random I/O nature of the virtualized environment, which of course is more expensive, on a dollar per GB basis, than hard disk drives. The single biggest problem however is the signi!cant increase in the number of discrete storage systems that service the environment. This “storage sprawl” threatens the return on investment (ROI) of virtualization projects and makes storage more complex to manage.

Virtual SAN- Deep Dive Into Converged Storage
DataCore™ Virtual SAN introduces the next evolution in Software-defined Storage (SDS) by creating high-performance and highly-available shared storage pools using the disks and flash storage in your servers. It addresses
the requirements for fast and reliable access to storage across a cluster of servers at remote sites as well as in high-performance applications.
DataCore Virtual SAN virtualizes the local storage on two or more physical x86-64 servers. It can leverage any combination of magnetic disks (SAS, SATA) and optionally flash, to provide persistent storage services as close to the application as possible without having to go out over the wire (network or fabric). Virtual disks provisioned from DataCore Virtual SAN can also be shared across the cluster to support the dynamic migration and failover of applications between hosts.
DataCore Virtual SAN addresses the challenges that exist today within many IT organizations such as single points of failure, poor application performance (particularly within virtualized environments), low storage efficiency and utilization, and high infrastructure costs.

Migration to Oracle 12c Made Easy Using Replication Technology
Logical replication allows migration between different hardware, operating systems, and Oracle versions with minimal downtime. It works by reading the redo logs of the source database in real time and applying the changes to the target database. Some preparation is required, such as testing and validating the migration. If issues occur during cutover to the 12c target, the original production system remains intact with no data risk. Logical replication provides an effective method for migrating to Oracle 12c with zero or near-zero downtime.

HIGH AVAILABILITY AND LOAD BALANCING FOR POSTGRESQL DATABASES: DESIGNING AND ...
The aim of the paper is to design and implement an approach that provides high availability and load balancing to PostgreSQL databases. Shared nothing architecture and replicated centralized middleware architecture were selected in order to achieve data replication and load balancing among database servers. Pgpool-II was used to implementing these architectures. Besides, taking advantage of pgpool-II as
a framework, several scripts were developed in Bash for restoration of corrupted databases. In order to avoid single point of failure Linux HA (Heartbeat and Pacemaker) was used, whose responsibility is monitoring all processes involved in the whole solution. As a result applications can operate with a more reliable PostgreSQL database server, the most suitable situation is for applications with more load of reading statement (typically select) over writing statement (typically update). Also approach presented is only intended for Linux based Operating System.
Graduate Project Summary
This document presents the design and implementation of MySQL/JVM, a framework for embedding the Java Virtual Machine (JVM) runtime environment into the MySQL database server. This allows stored procedures and functions in MySQL to be written in the Java programming language, leveraging Java's robust libraries. Currently, MySQL only supports a basic procedural language for stored procedures. MySQL/JVM aims to address this limitation and enable functionality like XML validation and encryption that are difficult to implement in MySQL's native language.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

- 14. Managing Physical Devices (continued) CFS is used in DBE/AC to provide the manageability of a file system in a large database environment. When used in DBE/AC with Oracle 9i RAC, Oracle accesses data files stored on CFS file systems via the ODM interface. This essentially bypasses the file system buffer cache and internal file system locking and allows asynchronous I/O. This means Oracle coordinates writing and locking of data. A single point of locking and buffering ensures maximum performance . Cluster Membership Services – VERITAS Cluster Server (VCS) is an open system clustering solution. It provides cluster membership services and high performance cluster interconnect software for RAC. The cluster membership services performs cluster integrity functions such as node monitoring in the RAC system and reconfigure the system automatically if a node failure is detected. The cluster interconnect provides the communication path for the cluster membership services and provides interprocess communication (IPC) for high-speed reliable communication between RAC processes. Oracle’s CacheFusion technology is an example of a RAC processes that utilize the high performance interconnect ..
