How to install Oracle Linux in kvm without a need to X server


Hi,
I managed to install Oracle Linux on kvm guest without a need to X console (no GUI, vnc or X11)
1. We can see the PXE menu
2. We can select image to install
3. We need to add console=ttyS0 to the PXE (cobbler is supporting this feature the same way as grub enable you to add parameter to the boot)

Disclaimer:
I tested this on Oracle Linux 7.5 using libvirt 1.5

# virt-install --hvm --connect qemu:///system --network=bridge:virbr0 --pxe --graphics none --name Oracle_Linux_7.4-x86_64 --ram=756 --vcpus=1 --os-type=linux --os-variant=rhel7 --disk path=/tmp/rhel7-machine.img,size=5 --console pty,target_type=serial --boot 'menu=on,useserial=on'

Data Guard - Changing IP Addresses

Image
When changing IP of a host we should update/recheck the following places: /etc/hosts or DNS listener.ora tnsnames.ora Database parameters (local_listener, remote_listener) Data Guard configuration This document is also relevant when changing the IP address of the connection between the hosts, other than the original IP addresses we used during the installation. When installation is done using the hostname and not the IP address, most of the changes are not relevant except for /etc/hosts. In this document, I will describe how to change the Data Guard Broker configuration.

Install Oracle Internet Directory (OID) in Standalone mode

Image
Oracle Internet Directory (OID) is an LDAP server which uses an Oracle database as a datastore. Client machines can use the OID for all TNS lookups. With OID. Once all client machines are configured correctly any modifications to the TNS lookups can be done from a central location reducing the amount of client machine administration. This guide is about installing and using Oracle Internet Directory in Standalone mode, no need for Oracle Fusion Middleware Infrastructure. Step-by-step guide Download Oracle Internet Directory (Part of identity management) from http://www.oracle.com/technetwork/middleware/id-mgmt/downloads/index.html Install OID, follow instructions: https://docs.oracle.com/en/middleware/lifecycle/12.2.1.3/inoim/installing-product-software.html#GUID-5D47117E-3983-4BED-BADB-CB7DDD63DB34 Starting the Installation Program: ./fmw_12.2.1.3.0_oid_linux64.bin Configure the Domain: $ORACLE_HOME/oracle_common/common/bin/config.sh Start the Servers for Standal
