Tuned is a Dynamic Adaptive Tuning System Daemon. According to Manual Page
tuned is a dynamic adaptive system tuning daemon that tunes system settings dynamically depending on usage. For each hardware subsystem a specific monitoring plugin collects data periodically. This information is then used by tuning plugins to change system settings to lower or higher power saving modes in order to adapt to the current usage. Currently monitoring and tuning plugins for CPU, ethernet network and ATA harddisk devices are implemented.
Assume you have a requirement of running two commands on 10 hosts.In this post I would like to show you how you can:1) Run multiple commands on remote host using ssh.2) Also instead of working on one host at a time serially, how can we execute the commands on multiple hosts in parallel to save the overall execution time.Example:Find the number of files under '/sdb/_read/' and '/sdb/_write/' directories on following 10 hosts.
I am pleased to announce the next Xen Project Hackathon to be held this spring. Although we call it a Hackathon, the event consists of several parallel sessions in which Xen Project developers will create, discuss and review designs and changes that impact Xen’s architecture. We’ll perform code reviews, discuss our future roadmap, work on improving the development process, tackle debug problems in the code base and cover other development related topics. Sessions are very interactive: typically there are no presentations.
GTID replication is new in mysql 5.6 and adds an unique ID to every transaction on the database. That transaction ID is then used to ensure the transaction is applied on the slave. So this removes the need to know where the master is in which logfile. GTID ensures there is consistency and automatically determines at which transaction the slave is at and which transaction is next on the list.
