I’m not a developer or software designer but as an user, I need to Single Sign-On for web applications that those made for a software solution. Some companies developing their solutions on this regard but Keycloak already developed and available as open-source software.
We have a problem on our Oracle Database servers which are hosting by Oracle Linux servers, when Oracle Databases putting to Maximum Availability protection mode, some workloads impacts performance whole database ecosystem. The workloads are related to some tasks which performed from by application servers and the tasks needs huge read/write I/O on storage arrays. We are using DELL EMC Unity/Unity XT (All Flash/Hybrid Flash) family in most of projects. I did lots of searches and found nothing at first step. I had only one clue, I/O block size was very large during performing tasks by database servers.
Operating system is the core of any system and we have to keep operating system update cause of preventing performance issues, unplanned downtime and fix security vulnerabilities. Windows (client and servers) has a standard terminology for receiving updates monthly and most of organizations using Windows Server Update Services to applying updates of multiple servers/client. Updates would be downloaded and installed on multiple servers/clients automatically but service downtime is always the biggest concern but another concern is installing updates on multiple machines and rebooting systems during planned downtime. PowerShell and WinRM would help us when they come as PSWindowsUpdate PowerShell module!
When you have no right sizing, when you have no control what be happened on database and when you didn’t any optimization, limiting using resources by database or any other system will necessary to help server to keep working without hang. Oracle Database be able to use all processing resources on a server and other process will be dead or hang if they couldn’t receive enough time for processing. CPU is the most important component and resource on any computer system, so if you want to stable system then the needed resources should be measured by right sizing or limiting some processes to delivering minimal resources to other processes.
As the world’s leading provider of Software-Defined Storage, High Availability, and Disaster Recovery software, LINBIT adds server clustering capabilities to any containerized, virtualized, or bare metal environment.
Parallel NFS (pNFS) is a part of the NFS v4.1 standard that allows compute clients to access storage devices directly and in parallel. The pNFS architecture eliminates the scalability and performance issues associated with NFS servers deployed today. This is achieved by the separation of data and metadata, and moving the metadata server out of the data path.
Ceph is most popular software-defined storage platform and offers Objec-Storage, Block Device and File System (CephFS) for storing data in modern data centers or public and private clouds. Best and popular solutions needs alternatives as well. So at this post, we’ll review some alternatives for Ceph.
This is a review post about an amazing software which made to be time reference in network with some unique features. Network Time System made by Softros Systems and provides a solution to system time maintenance problems.
This is a sad story. We are not using any Directory Service such as Active Directory (I was fighting for active directory during past 4 years!) because of Gap of Knowledge in our department.
HashiCorp is one of leaders which providing automation tools for large-scale of cloud solutions. Let’s see which solutions provided by HashiCorp.
