In order to use this disk, before we can mount it we will have to create a partition first and then file system. So let’s create a partiton first. Select the newly attached which disk you want to
Step By Step Streaming Replication In PostgreSQL 12 In this demonstration,We’ll see how to setup a Streaming Replication in PostgreSQL 12 running on Oracle Linux 6.8 Here, I assume that you have two servers (Primary/Master & Standby/Slave) having PostgreSQL 12 installed. And Database cluster is initialized using initdb on both the servers. If not, you might want to see Installation of PostgreSQL here.

Creating & Deploying Virtual Machine on ESXi Server Creating VM is not rocket science in ESXi and it is quite similar to creating VMs in any hypervisor like VM Ware or VirtualBox. In the last article, we did deployment and configuration of ESXi Server on Bare-Metal machine. In today’s article, we’ll deploy a VM on ESXi Server with Oracle Linux 7. Here I assume that you already have ISO of Oracle Linux(or any). If you haven’t downloaded any, get Oracle
