Oracle Autonomous Database and DevOps: A Simple Approach to Utilization – Part 5
Category: Cloud Author: BRUNO REIS Date: 5 years ago Comments: 0

Oracle Autonomous Database and DevOps: A Simple Approach to Utilization - Part 5

This article is the fifth and final part of the Oracle Autonomous Database and DevOps article series. For a better understanding, I recommend to read the articles “Oracle Autonomous Database and DevOps: A Simple Approach to Use – Part 1”, “Part 2”, “Part 3” and “Part 4” before proceeding with the steps in this article.

 

As the previous article dealt with the creation of the Linux application server within Oracle Cloud, in this article we will proceed with the creation of microservices using Docker and connecting a JAVA application to the cloud database. To start let’s get some concepts:

 

 

What are microservices?

 

According to Chris Richardson, “is a style of architecture that structures an application as a collection of services that are:

 

  • Highly sustainable and testable
  • Frankly coupled
  • Independently deployable
  • Organized around business resources. ”
 
What is node.js?

 

According to the manufacturer’s official website, “Node.js is an open source, cross-platform JavaScript execution environment.”

 

PS: This article will not show the coding of the application, but only the loading of it.

 

Now that we have a brief description of micricroservices and node.js, let’s proceed with the creation of our microservices:
 
 
Creating node.js microservices: Make sure Docker is running on your machine (For more information on Docker see the first article of this series):

At this moment you can pull your app image at https://github.com  as in the example below:







[root@oc8226237722 /]# git clone https://github.com/brunors/appte.git  ((link will not be available after  this article is published))




Cloning into 'appte'...

remote: Enumerating objects: 1045, done.

remote: Total 1045 (delta 0), reused 0 (delta 0), pack-reused 1045

Receiving objects: 100% (1045/1045), 3.49 MiB | 1.95 MiB/s, done.

Resolving deltas: 100% (173/173), done.




Open the port on your computer for the application to start. As we chose in the previous article will be port 3055:




[root@techdatabasketblog /]# firewall-cmd --zone=public --permanent --add-port=3055/tcp

success

 

 

Install Oracle Client on your computer, you can find it on the OTN website and download it:

 

 

Copy the wallet used in previous articles to create the secure connection to a directory that will be used for the container image:
 
[root@techdatabasketblog wallet_APPtechdatabasket]# unzip /tmp/wallet/Wallet_techdatabasket.zip -d /wallet_APPtechdatabasket/

Archive:  /tmp/wallet/Wallet_techdatabasket.zip

  inflating: /wallet_APPtechdatabasket/cwallet.sso 

  inflating: /wallet_APPtechdatabasket/tnsnames.ora 

  inflating: /wallet_APPtechdatabasket/truststore.jks 

  inflating: /wallet_APPtechdatabasket/ojdbc.properties 

  inflating: /wallet_APPtechdatabasket/sqlnet.ora 

  inflating: /wallet_APPtechdatabasket/ewallet.p12 

  inflating: /wallet_APPtechdatabasket/keystore.jks 

[root@techdatabasketblog wallet_APPtechdatabasket]#


Change the sqlnet.ora values ​​to:

 

WALLET_LOCATION = (SOURCE = (METHOD = file) (METHOD_DATA =

(DIRECTORY=$TNS_ADMIN)))

 

Be in the directory containing the wallet, the Oracle Client and start Docker with the image name (in this article  is appte):

 

$ docker build -t appte   .




Check the image:

 

[root@techdatabasketblog]# docker images -a

appte                                           latest              65463ysdbe26       3 weeks ago         171 MB

 

 

Start the image on port 3055 as we chose:

 

docker run -i -p 3055:3055 -t appte  sh

/ #

 

Change your user credentials, password and connection string in the application.

 

Run the server.js script:

 

node server.js &

 

The results will be something like this:

 

appte listening on port 3055




You can see your application in a web browser as http://{SEUIP}:3055

 

 

Now that we have created the  microservices, let’s make a connection of a JAVA application to the ATP:

 

Connect to the provisioned server and as root install java:

 

[root@techdatabasketblog ATPDocker]# ssh [email protected]

Enter passphrase for key '/root/.ssh/id_rsa':

Please login as the user "opc" rather than the user "root".




Connection to 129.146.128.2 closed.

This finished  the series of articles on the simple approach of Oracle Autonomous Database and DevOps. The idea for this series of articles came from my participation in Oracle Code Rome 2019 in Italy, where I got a lot of knowledge that made me explore this DevOps field further with the ATP database and as mentioned in the first article we started with the Docker setup and later in the following articles on Oracle Cloud database and server provisioning on Oracle Cloud and we end with a brief representation of microservices and java with the ATP database. However, there are a number of features that can still be explored within Oracle Cloud, so create your account and explore the Oracle Cloud world.

Oracle Autonomous Database and DevOps: A Simple Usage Approach – Part 4

Oracle Autonomous Database and DevOps:
A Simple Usage Approach - Part 4

 
 
This article is the fourth part of the series of articles on Oracle Autonomous Database and DevOps. For a better understanding, I recommend reading the “Oracle Autonomous Database and DevOps: A Simple Usability Approach – Part 1”, “Part 2” and “Part 3” articles before proceeding with the steps in this article.
 
As in the previous article we treated the secure connection of the ATP instance with Oracle SQL Developer using the wallet file of the provisioned instance, in this article we will proceed with the creation of the Linux application server. An interesting factor in this topic is that the Linux server will be created within the Oracle Cloud and thus showing the versatility of the Oracle Cloud. To start let’s build some concepts:
 
Why create the Virtual Cloud Network?
 
According  to Oracle Corp., “Before you start an instance, you must have a virtual cloud network (VCN) and a subnet to start it. A subnet is a subdivision of your VCN. The subnet directs the traffic according to the route table. “.
 
Therefore, follow these steps:
 
 – Creating the virtual network (Virtual Cloud Network): In the Oracle Cloud menu click on “Networking” and later “Virtual Cloud Network”:
In the Virtual Cloud Networks tab click on the “Create Virtual Cloud Network” button
You will then be presented with the screen to create the Virtual Cloud Network, where it is necessary to specify all the information for the VNC configuration:
In the Virtual Cloud Network tab choose the option “Create Virtual Cloud Network plus related resources” to create the VNC only with public subnets:
Click the “Create Virtual Cloud Network” button and a screen with confirmation of creation will be displayed:
Thus it will be possible to verify the VCN created:
Click the name of the VCN, in the case of the example of this article “VirtualCloud”.
Then click on “Security Lists” in the menu:
Click “Default Security Lists for VirtualCloud”
On the next screen click on “Edit All Rules”: “
Afterwards, under the “Ingress Rule 3” tab, click the “Another Ingress Rule”
In the next Ingress Rule add the following data:
   Source CIDR : 0.0.0.0/0
    Destination Port Range : 3055 (just an example)
After entering the information click on “Save Security List Rules”:
With the Virtual Cloud Network configured, we will proceed with the provisioning of the Linux machine.
Provisioning the Linux server: In the initial menu of Oracle Cloud click on “Compute” and later on “Instances”:
On the next tab, click the “Create Instance” button:
In the Create Compute Instance tab, provide the requested information:
 
Name: Choose a name for your instance. (In the example: VMLINUXmachine)
 
Select an available domain for your instance: Choose the first available domain (In the example: ysjg: PHX-AD-1)
 
Choose an operating system or image source: Keep the option available from Oracle.
Image Operating System: Oracle Linux 7.6
Choose instance type: Choose “Virtual Machine”
Shape: We will use the option “VM.Standard2.1”
Image Version: Please select the latest version, 2018.09.25-0 (latest)
Configure boot volume: Keep the default option.
SSH Keys: Because Linux operating systems use SSH keys for authentication, you must provide a public key. Click “Choose SSH key file” and provide a public SSH key.
Then click on the “create” button:
While the server is being provisioned, the status displayed will be “Provisioning”:
Once the process is finished, the status is changed to “RUNNING”:
An interesting fact is that from this moment it is already possible to make ssh connection with the created server:

 

 

[root@techdatabasketblog /]# ssh 129.146.128.2

Oracle Autonomous Database and DevOps: A Simple Usage Approach – Part 3
Category: Cloud Author: BRUNO REIS Date: 5 years ago Comments: 0

Oracle Autonomous Database and DevOps: A Simple Usage Approach - Part 3

This article is the third part of the series of articles on Oracle Autonomous Database and DevOps. For a better understanding, I recommend reading the articles “Oracle Autonomous Database and DevOps: A Simple Usage Approach – Part 1” and “Oracle Autonomous Database and DevOps: A Simple Usage Approach – Part 2” before proceeding with the steps of this article.
As in the previous article the provisioning of the Oracle Autonomous Database version 18c in the Oracle Cloud was discussed, in this article we will proceed with the use of the database wallet file created to make a secure connection to the provisioned instance and later the first tests with Oracle SQL Developer. However, before starting, let’s build some concepts:
What is Oracle SQL Developer?

 

            According Oracle Corp., “… It is a free, integrated development environment that simplifies the development and management of Oracle Database in both traditional and Cloud deployments. SQL Developer offers complete end-to-end development of your PL/SQL applications, a worksheet for running queries and scripts, a DBA console for managing the database, a report interface, a complete data modeling solution, and a migration platform for moving your 3rd party databases to Oracle. ” “

 

            Now that you have a brief understanding of what Oracle SQL Developer is, let’s start using the wallet file from the provisioned database and thus establishing a secure connection. To do this, follow these steps:
 
– Use of the wallet file of the provisioned database: In the Oracle Cloud menu click the option Autonomous Transaction Processing (last option in the figure below):
In the next menu, click the name of the provisioned instance. As mentioned in the previous article, the provisioned instance was called techdatabasketinstance:
In the next menu, click the name of the provisioned instance. As mentioned in the previous article, the provisioned instance was called techdatabasketinstance:
After that you can download the wallet file by clicking the “Download” button:
Before starting the download you will be asked to create a password to access the wallet file in the future:
 After the download, create a directory to store the wallet file. As mentioned in the previous article, the directory “/tmp/wallet” was created as an example:
[brunors@techdatabasketblog Downloads]$ pwd

/home/brunors/Downloads

[brunors@techdatabasketblog Downloads]$ cp Wallet_techdatabasket.zip /tmp/wallet

[brunors@techdatabasketblog Downloads]$ ls -ltr /tmp/wallet

total 20

-rw-rw-r--. 1 brunors brunors 19841 Apr 22 16:39 Wallet_techdatabasket.zip

[brunors@techdatabasketblog Downloads]$ 

 

 

Now that we have the wallet file in the desired location, we will proceed with the instance connection using Oracle SQL Developer:




- Oracle SQL Developer installation: If you do not have Oracle SQL Developer installed on your machine, simply check the basic requirements such as having Oracle JDK 1.8, the updated version 121 or higher.




 

 

[root@brunors Downloads]# yum install jdk-8u211-linux-i586.rpm

Complete!

[root@brunors Downloads]# 

 

 

Find out where the JDK was installed through the “find. -name ‘javac'” command. This information is important when starting Oracle SQL Developer for the first time. In the example below, the JDK was installed in /usr/java/jdk1.8.0_211-i586/bin.

 

 

[root@brunors /]# find . -name 'javac'

./etc/alternatives/javac

./usr/java/jdk1.8.0_211-i586/bin/javac

./usr/bin/javac

./var/lib/alternatives/javac

 

 

– Connecting the ATP instance with Oracle SQL Developer: Since the JDK is now installed, we will continue with the secure connection between Oracle SQL Developer and the ATP instance created in the Oracle Cloud. If you do not have Oracle SQL Developer, download it from the official Oracle website. Start Oracle SQL Developer and provide the JDK installation path:

 

[root@brunors sqldeveloper]# ./sqldeveloper.sh

 

 Oracle SQL Developer

 Copyright (c) 2005, 2018, Oracle and/or its affiliates. All rights reserved.

  

Type the full pathname of a JDK installation (or Ctrl-C to quit), the path will be stored in /root/.sqldeveloper/18.3.0/product.conf

/usr/java/jdk1.8.0_211-i586/    

 
After this Oracle SQL Developer starts:
Click Add Connection with the “+” button:
On the next screen you will be asked for the connection information of the ATP instance. Provide the following information:

 

Connection Name: It's just a name to identify the connection to the instance.

 

Username: admin

 

Password: ****************** (database creation password)

 

Connection Type: Cloud Wallet

 

Role: Default




Configuration File: Click "Browse" and choose the directory where the wallet file is located.




Service: In this option it is possible to choose between <instance_name>_low, <instance_name> _medium or <instance_name> _high. In this article we will be using the type of parallelism high. So, the chosen option will be techdatabasket_high.

  
 Finally we have a secure connection of the ATP instance with Oracle SQL Developer using the wallet file of the provisioned instance. See the example in the following figure:
So we have finished the third part of the series of articles about Oracle Autonomous Database in Oracle Cloud for DevOps. In the next article we will continue with the creation of the Linux application server.

Oracle Autonomous Database and DevOps: A simple usage approach – Part 2
Category: Cloud Author: BRUNO REIS Date: 5 years ago Comments: 0

Oracle Autonomous Database and DevOps:
A simple usage approach – Part 2

            This article is the second part of the series of articles about Oracle Autonomous Database and DevOps. For a better understanding, I recommend reading the article “Oracle Autonomous Database and DevOps: A Simple Usage Approach – Part 1” before proceeding with the steps in this article.
 
As in the previous article the Docker configuration was handled, we will begin to provision the Oracle Autonomous Database version 18c in the Oracle Cloud.
 
– Provisioning the Oracle Autonomous Database in the Cloud: Before provisioning the database it is necessary to create a Compartment. If you have not yet created click on “Identity” and later on “Compartments” under the “Governance and Administration” tab of the menu:

 

 

Then click “Create Compartment” if there is no existing compartment: The root compartment is the first compartment created. From this it is possible to create other compartments by using it as an option in the “Parent Compartment” tab.
Fill in the required fields as the Name of the compartment, any description in the Description field and click on the “Create Compartment” link.
In the above example the name “brunoreis” was chosen as the name of the compartment. In addition, because Oracle recommends creating databases in compartments other than root, a compartment called TECHDATABASKET was created, represented by the image below:

 

Now with the compartment created we will proceed with the creation of the Autonomous Transaction Processing (ATP) instance.
 
On the Oracle Cloud menu, click Autonomous Transaction Processing:

 

Click the Create Autonomous Database button:
In the Create Autonomous Database tab fill in all requested information such as database name, CPU core, storage etc. An important note in this topic is that you can choose the type of workload as AUTONOMOUS DATA WAREHOUSE or AUTONOMOUS TRANSACTION PROCESSING. However, in this article we are only using the AUTONOMOUS TRANSACTION PROCESSING option.
Make sure you have provided all the information correctly and click on “Create autonomous database”:
 
 
During the creation of the database, we will be shown the status “Provisioning”
Once the provisioning is finalized, the status is changed to “Available”:
            In the next article we will discuss the connection between Oracle SQL Developer using the database wallet file created in the Oracle Cloud and also the creation of a Linux machine where the application will be implemented.

Oracle Autonomous Database and DevOps: A simple usage approach – Part 1
Category: Cloud Author: BRUNO REIS Date: 5 years ago Comments: 0

Oracle Autonomous Database and DevOps:
A simple usage approach – Part 1

            This article explains the creation of an Oracle Autonomous Database instance in the Oracle Cloud  for the usage of programmers(some tests examples with some programming languages and Oracle SQL Developer). Let’s build some concept to start:

 

What is the Oracle Autonomous Database?

 

            According  to Oracle Corp, it is “the first standalone cloud data manager that provides application for patches, upgrades and tuning, including performing maintenance tasks on the database without human intervention.”. In addition, Oracle itself explains 3 features of this new database model that are:
  • According to the Oracle Corp. this is “
  • Self-Driving: Thus reducing human labor;
  • Self-Securing: Protecting yourself from third-party attacks;
  • Self-Repairing: Will try to keep the database running regardless of the error, as it will attempt to resolve the issue autonomously.

 

What is Docker?

 

It is a computer program that performs virtualization at the operating system level.
 
            Now that you have a brief understanding of what is the Oracle Autonomous Database we will begin to configure the database in the Oracle Cloud for programming purposes. To do this, we will follow the following steps:

 

Account configuration in the Oracle Cloud: In this step you will need to create the account  in the Oracle Cloud through the https://cloud.oracle.com/home link. I will not go into detail in this topic because  someone recently had an article published in OTN Brazil that details step by step this topic. The name of the article is “Using Oracle Autonomous Transaction Processing” and can be found on the following link:
https://www.oracle.com/technetwork/pt/articles/cloudcomp/utilizando-oracle-atp-5462247-ptb.html .

 

– Docker Software Installation: This software can be found on the manufacturer’s official website https://www.docker.com/ and the installation depends on the type of operating system. In this article we will be using the Red Hat 7 operating system. Here is an example below:

 

 

[root@oc8226237722 ~]# yum install docker

Loaded plugins: downloadkvmonly-background, techdatabasketblog-check-lotus-updates, techdatabasketblog-check-

              : upgrade, techdatabasketblog-check-xorg-updates, techdatabasketblog-repository, langpacks,

              : post-transaction-actions, refresh-packagekit, versionlock

RHEL-76-x86_64-updates                                   | 3.3 kB     00:00    

RHEL7-x86_64-techdatabasketblog-upgrade                                 | 3.3 kB     00:00
