VM Post Provision Steps

Steps to do after provisioning a VM to enable connectivity to the internet and assign an IP address

--OLD OS RELEASES--

Edit the following file:
/etc/sysconfig/network-scripts/ifcfg-ens192

vi /etc/sysconfig/network-scripts/ifcfg-ens192
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=static #Changed from dhcp to static or none
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=ens192
UUID=590dc84a-35ac-40bd-a3d9-0e62950e5018
DEVICE=ens192
ONBOOT=yes #Changed from no to yes
IPADDR=172.16.1.17 #Add IP address
NETMASK=255.255.255.0 #Add netmask
GATEWAY=172.16.1.254 #Add gateway
DNS1=8.8.8.8 #Add DNS entry 1 (max 3)
DNS2=8.8.8.4 # Add DNS entry 2
[root@slr-app-server network-scripts]#

Restart network:
systemctl restart network

Set the hostname of the server:
hostnamectl set-hostname slr-app-server

Check ping connectivity:
ping 8.8.8.8

Reboot the server to confirm that post-provisioning steps were a success.


--NEW OS RELEASES--

Newer OS releases use nmcli to configure network connectivity.

[root@localhost network-scripts]# nmcli device status
DEVICE  TYPE      STATE      CONNECTION
ens34   ethernet  connected  ens34
lo      loopback  connected (externally) lo

[root@localhost network-scripts]# nmcli connection show
NAME   UUID                                  TYPE      DEVICE
ens34  7f5bb589-3c95-39a4-8721-2729f7ff4ed7   ethernet  ens34
lo     7f3309af-7136-4973-957a-a671b6df90eb   loopback  lo

[root@localhost network-scripts]# nmcli connection modify ens34 \
  ipv4.addresses 192.10.100.63 \
  ipv4.gateway 192.10.100.1 \
  ipv4.dns "8.8.8.8 8.8.8.4" \
  ipv4.method manual
  
[root@localhost network-scripts]# nmcli connection down ens34

[root@localhost network-scripts]# nmcli connection up ens34

Set a new hostname to the server.

hostnamectl set-hostname <new-hostname>

Installing Oracle Database 19c on Linux 8 (OL8) Server

Image
Step 1 - Install the Relevant Software Install the Oracle Database 19c Enterprise Edition 19.3.0.0.0 from Oracle Software Delivery Cloud or any other method you prefer. (If your server has an internet connection you can use the wget method to install the software) As a best practice create a separate directory named 'SOFTWARES' where you can move installation files. Step 2 - Add the following lines to the ' /etc/sysctl.conf ' file as root user. fs.file-max = 6815744 kernel.sem = 250 32000 100 128 kernel.shmmni = 4096 kernel.shmall = 1073741824 kernel.shmmax = 4398046511104 kernel.panic_on_oops = 1 net.core.rmem_default = 262144 net.core.rmem_max = 4194304 net.core.wmem_default = 262144 net.core.wmem_max = 1048576 net.ipv4.conf.all.rp_filter = 2 net.ipv4.conf.default.rp_filter = 2 fs.aio-max-nr = 1048576 net.ipv4.ip_local_port_range = 9000 65500 Step 3 - Add the following lines to a file called ' etc/security/limits.d/oracle-database-preinstall-19c.conf'  file or...

Oracle GoldenGate Real-Time Replication (Unidirectional)

Image
Below is the specs of the source and target I used for this demonstration: Source: OL 7.9 / DB 11.2.0.2 / GoldenGate 12.3 / Classic Extract Target: OL 8 / DB 19c / GoldenGate 19.1 / Integrated Replicat (The reason I used GoldenGate 12.3 in the source server is since GoldenGate 19c does not support Oracle Database 11.2.0.2 The source DB server use the classic extract method to extract the trail files since integrated extract method is not supported.) Ports to be opened: 7809               Source --> Target -- Manager Port 7810-7820     Source --> Target -- Collector Ports 1521               Source --> Target -- Listener Port (Strictly not necessary but better to have opened) 22                    Bidirectional -- SSH Port Make sure the tns entries are clearly specified in the tnsnames.ora file.

Installing WebLogic 12.2.1 on Oracle Linux 8 Server

Image
Step 1 - Download the relevant Software Oracle Fusion Middleware 12c Infrastructure Java Development Kit 1.8.0_202 As a best practice place the downloaded software in a separate directory such as ' SOFTWARES ' Step 2 - Create the following groups and the weblogic user [root@testserver-k opc]# groupadd -g 54321 oinstall [root@testserver-k opc]# useradd -u 54321 -g oinstall weblogic Step 3 - Changed the password for weblogic user [root@testserver-k opc]# passwd weblogic Step 4 - Created the directories in which the WebLogic software will be installed [root@testserver-k opc]# mkdir -p /u01/app/oracle/product/12.2.1 [root@testserver-k opc]# mkdir -p /u01/app/oracle/config/domains [root@testserver-k opc]# mkdir -p /u01/app/oracle/config/applications [root@testserver-k opc]# chown -R weblogic:oinstall /u01 [root@testserver-k opc]# chmod -R 775 /u01/ Step 5 - Appended the following entries into the '/home/weblogic/.bash_profile' file. [weblogic...
