Launch OCI free tier ATP and ADW using Terraform on Window platform

Terraform template available at GitHub will not work directly with OCI free tier ADB database service. You have to adjust some parameter inside the Terraform template to make it compatible with free tier ADB services.

We will Launch two ADB databases one for the ATP database and one for the ADW database using a single command then we will play with ADB using OCI CLI and then finally we will destroy the created infrastructure using a single command.

Download the terraform for window10.
https://releases.hashicorp.com/terraform/0.12.19/terraform_0.12.19_windows_amd64.zip

Installation Steps
copy the downloads for windows version.
copy inside program file and configure windows path variable

 

 

C:\Users\oracle-learn>terraform
Usage: terraform [-version] [-help] <command> [args]

The available commands for execution are listed below.
The most common, useful commands are shown first, followed by
less common or more advanced commands. If you're just getting
started with Terraform, stick with the common commands. For the
other commands, please read the help and docs before usage.

Common commands:
apply Builds or changes infrastructure
console Interactive console for Terraform interpolations
destroy Destroy Terraform-managed infrastructure
env Workspace management
fmt Rewrites config files to canonical format
get Download and install modules for the configuration
graph Create a visual graph of Terraform resources
import Import existing infrastructure into Terraform
init Initialize a Terraform working directory
output Read an output from a state file
plan Generate and show an execution plan
providers Prints a tree of the providers used in the configuration
refresh Update local state file against real resources
show Inspect Terraform state or plan
taint Manually mark a resource for recreation
untaint Manually unmark a resource as tainted
validate Validates the Terraform files
version Prints the Terraform version
workspace Workspace management

All other commands:
0.12upgrade Rewrites pre-0.12 module source code for v0.12
debug Debug output management (experimental)
force-unlock Manually unlock the terraform state
push Obsolete command for Terraform Enterprise legacy (v1)
state Advanced state management

If you haven’t already uploaded your public key through the console,

follow the instructions on the page linked below in the section ‘How to
upload the public key’:

https://docs.cloud.oracle.com/Content/API/Concepts/apisigningkey.htm#How2
C:\Users\oracle-learn\bin>C:\Users\oracle-learn\.ssh\id_rsa.pub

C:\Users\oracle-learn\bin>oci –help

Once everything is configured correctly you can run a few commands to try out the client. The basic syntax is:
$ oci

$ oci
Some of the available services are:

Core (Networking, Compute, Block Volume, etc.)
Database
IAM
Load Balancing
Object Storage

#Launch Compute instance

When you launch an instance you have to provide the following information, some of which you’ve already obtained:

compartment-id
availability-domain
subnet-id
image-id
shape

Sample commands to find the required information.
oci iam user list –compartment-id
oci iam availability-domain list
oci compute shape list -c
oci compute image list -c

You can use -h option at end of the command to find an help related to specific command option.
oci compute image list -h
oci compute shape list -h

Syntax:
oci compute instance launch –availability-domain “” -c –shape “” –display-name “” –image-id –ssh-authorized-keys-file “” –subnet-id

Example:

oci compute instance launch --availability-domain "AARS:AP-MUMBAI-1-AD-1" -c ocid1.compartment.oc1..ggfdh434332sfsdfsdfsdfsf --shape "VM.Standard.E2.1" --display-name "MyFirstMachineFromCLI" --image-id ocid1.image.oc1.ap-mumbai-1.aaaaaaaaka7f3qhfuobx2s7dqfgbcx5klllh5xlflbgzb5pymqsnuphehk2a --ssh-authorized-keys-file "C:\Users\oracle-learn\.ssh\id_rsa.pub" --subnet-id ocid1.subnet.oc1.ap-mumbai-1.aaaaaaaah44xlfte72zz4yrgrp5pqc3ndqy5atc3kqlfmz4lzwdlsdlhyoya

#List Compute instances
oci compute instance list --compartment-id ocid1.compartment.oc1..ggfdh434332sfsdfsdfsdfsf

Performs one of the following power actions on the specified instance

[1] * **START** – Powers on the instance.

oci compute instance action --instance-id ocid1.instance.oc1.ap-mumbai-1.fdsfdsfsdfsdfdsf343sdfsdfsfsdf --action START --wait-for-state RUNNING

[2] * **STOP** – Powers off the instance.

oci compute instance action --instance-id ocid1.instance.oc1.ap-mumbai-1.fdsfdsfsdfsdfdsf343sdfsdfsfsdf --action STOP --wait-for-state STOPPED

[3] * **SOFTRESET** – Gracefully reboots instance by sending a shutdown
command to the operating system and then powers the instance back
on.

oci compute instance action --instance-id ocid1.instance.oc1.ap-mumbai-1.fdsfdsfsdfsdfdsf343sdfsdfsfsdf --action SOFTRESET --wait-for-state RUNNING

[4] * **SOFTSTOP** – Gracefully shuts down instance by sending a
shutdown command to the operating system.

oci compute instance action --instance-id ocid1.instance.oc1.ap-mumbai-1.fdsfdsfsdfsdfdsf343sdfsdfsfsdf --action SOFTSTOP --wait-for-state STOPPED

[5] * **RESET** – Powers off the instance and then powers it back on.

oci compute instance action --instance-id ocid1.instance.oc1.ap-mumbai-1.fdsfdsfsdfsdfdsf343sdfsdfsfsdf --action RESET --wait-for-state RUNNING

#Terminate Compute instance
oci compute instance terminate --instance-id ocid1.instance.oc1.ap-mumbai-1.fdsfdsfsdfsdfdsf343sdfsdfsfsdf

OTNYathra2017 @Mumbai

 

I have provided enough information about the OTN Yathra, In my previous artical “about-otnyatha”

In this artical I have decided to sharing my experiences about the sessions which i have been attended.

I have choose the Mumbai location because it is near to Ahmedabad.

I had attended below sessions at OTN Yathra 2017 @Mumbai organized by AIOUG / OUAG

1.)  “High Performance Database in Oracle Bare Metal Cloud Services” by Vivek Sharma

This session was mainly focus on Oracle Bare Metal Cloud Services offering and options by Oracle.

2.)   “Oracle and Docker – Everything you want to know to run your workload in docker container” by Umesh Tanna

I was really impress by Umesh, the way he is explaining the docker and oracle offering was quite good.

3.)  Oracle GoldenGate – IRCTC by Veeratteshwaran

This session has change my perception about the replication technology.

4.)  Building Private Cloud with Open Infrastructure by Nitin Gupta

This is the best session that actually I’m interested to know what is offering and differce option of oracle in Open Infrastructure.

5.)  12 things DBA’s will love about 12.2 by Connor McDonald

I’m feeling lucky that i choose this session because Connor is great presentation skills and sharing his experience with different examples

These all sessions were really helpful and it’s help me lots to to fill with new angle of thinking amount the upcoming technologies

I’m really greatfull to all the volunteers of AIOUG and specific to Mumbai Local Chepter volunteers who had nicely organized this event.

I’m also thankful to all the sponsors.

If you have any quesions or queries please comment here, I’m happy to share my own views and experiences about these new technologies.

Cloud-Amazon RDS

Amazon Relational Database Service

The basic building block of Amazon RDS is the DB instance. A DB instance is an isolated database environment in the cloud.  A DB instance can contain multiple user-created databases, and you can access it by using the same tools and applications that you use with a stand-alone database instance. You can create and modify a DB instance by using the Amazon RDS command line interface, the Amazon RDS API, or the AWS Management Console.
