[ORACLE] Create OCI DB System using the console.

Hello everyone!

I hope you're doing well.

Today, I going to show you how to create a new DB system in OCI.

Let's get started.

 

1) Select Oracle Database -> Oracle Base Database Service in the OCI console and click on "Create DB system".

 

 

 

2) Enter the compartment and DB system names.

 

3) Click on "Change Shape" and select your preferred shape.

 

 

4) Configure the storage. To do this, click on "Change Storage".

 

Select the storage management software, and configure the storage performance and size.

5) Configure the Oracle Database software edition and the DB system node count.

 

We have 4 database software edition options: 

• Standard Edition
• Enterprise Edition
• Enterprise Edition High Performance
• Enterprise Edition Extreme Performance.

 

6) Add the ssh key and select whether to use your own licences or the license included model.

 

7) Now, specify the VCN and subnet to want to use.

 

 

The private IP will be created automatically, if you don't configure it.

 

 

8) Click "Next".

 

 

9) Now let's configure the database information.

 

Click "Change database image".

10) Select the database image.

 

 

11) Configure the SYS and TDE passwords, as well as the backup service.

Finally, click on “Create DB system”.

After 90 minutes (average), you will have a DB system ready to use.

And that's it. I hope it helps you.

[Oracle Autonomous JSON] How to configure and using the Oracle API for MongoDB on Oracle Autonomous JSON Database - Part 2

 Hello everyone

In my last post, I presented how you can configure the Oracle Autonomous JSON Database to use the API for MongoDB.

And today, we're going to use the API to connect into MongoDB shell, create a simple collection and use those documents in the ADJ console.

If you want to see the first post, feel free to click here. 

But always remember:

1. This step-by-step worked for me, but it may not work for you.
2. It's a basic and limited environment. The real life will be different, for sure.
3. This post is for study and testing as well, and has no concern for performance and security best practices.

I have a MongoDB Intance in OCI Compute and I'm going to connect MongoSH in my ADJ using the connection string that I created in the first post. My user is named ADMIN:

mongosh -u admin -p XXXZZZ 'mongodb://XXZZZ-IRONMAN.adb.sa-saopaulo-1.oraclecloudapps.com:27017/admin?authMechanism=PLAIN&authSource=$external&ssl=true&retryWrites=false&loadBalanced=true'

I'll create a new collection and a new document using MongoSH. After that I'll create a new document using ADJ console and at the end I'll select this data in the console and MongoSH as well.

This example was adapted from the post "SQL NESTED Clause Instead of JSON_TABLE in Oracle Database 19c" from amazing ORACLE-BASE. 

So, let's get started!!!

1) I'll connect in MongoSH using my connection string:

2) Now, I'll access the ADJ console. Click on the "Database Actions" button and select the option "JSON".

  

3) First, I'll create a new decument in the MongoSH shell.

4) The second document will be created in the ADJ console. For this, click in "New" button in the ADJ console.

Click on the "Create" button and he massage bellow should appear.

And now, I have 2 documents in my collection.

And for read operations, I have two options:

1)  Click on the "Database Actions" button and select the option "SQL".

2) I'll create my SQL queries with the same SQL statements used in relational databases.

Using NESTED and WHERE, for example.

3) Finally, I may read my documents usinf MongoDB statements, for shure!!!

It's really cool, right!!!

In the next post, I'll show you how enabling REST is easy in ADJ.

I hope this post will help you!!!

[Oracle Autonomous JSON] How to configure and using the Oracle API for MongoDB on Oracle Autonomous JSON Database - Part 1

Hello all!!!

How are you doing?

Today I'll show how you can create an Autonomous Database JSON instance on OCI Free Tier and how you can connect your MongoDB with this instance using Oracle Database API for MongoDB. 

In Part 2, I'll create new collections in the MongoDB shell and demonstrate how we can use these in the ADJ console using JSON and traditional SQL syntax.

The MongoDB is running on OCI Compute Instance :) 

But always remember:

1) This step-by-step worked for me, but it may not work for you.

2) It's a basic and limited environment. The real life will be different, for sure.

3) This post is for study and testing as well, and has no concern for performance and security best practices.

So, let's get started!!!

1) Create a VCN. I'm not show the step by step for this, but it's really easy. Google helps you!!!

2) Now, I'll create the ADJ for testing. Click on Create Autonomous Database.

This is the most important setup that you need. For access the Oracle Database Actions Launchpad, you must have set "Secure access from allowed IPs and VCNs only" and put our VCN and our IP here. It's mandatory!!!

I'll insert my IP address and click "Add access control rule" to add my VCN, as well!

To finish, click "Create Autonomous Database" and wait!

3) ADJ created, it's time to check access to MongoDB.

For this verification, we need the link for mongosh. Click on "Database actions". 

In the end of the page, click on "Oracle Database API for MongoDB".

Copy the MongoDB connection string URL.

Finally, access the MongoDB server and test the connection.

Oh my god! Error!!!! Why????

The error "Client network socket disconnected before secure TLS connection was established" is easy to solve.

We also need to put the Compute Instance Public and Private IP where we run the MongoDB on "Access control list".

And now, I have succeeded!!!

In the next post, I going to create some collections and load documents into MongoDB console, and I'll work with those tables in the ADJ console using the "Traditional Select Syntax".

It's going to be cool! :) 

I hope this post helps you!

[Oracle Autonomous JSON] Create new Instance on OCI Free Tier

Hello all!!!

How are you doing?

Today I'll show how you can create an Autonomous Database JSON instance on OCI Free Tier.

I'll use the instance in future posts about JSON and Oracle.

But always remember:

1) This step-by-step worked for me, but it may not work for you.

2) It's a basic and limited environment. The real life will be different, for sure.

3) This post is for study and testing as well, and has no concern for performance and security best practices.

So, let's get started!!!

1) Select "Oracle Database" in menu

2) Click on "Autonomous JSON Database"

3) Click on "Create Autonomous Database"

4) Select the Compartment - Never use the Root compartment, put other information (Display name, Database name) and password as well.

And now, I'm waiting for the conclusion of the process.

A few minutes later, the Instance is ready for use.

That's it my friend!! Easy!!!

I hope it helps you!
