Stack Monitoring for EBS

The Stack Monitoring service is a recent addition to the OCI Observability & Management family.

If you are running Oracle E-Business Suite (EBS) application today you will now be able to perform an auto discovery of all related resources in OCI Stack Monitoring. It will collect metrics specific for your EBS resources as well as ability to perform correlation across the EBS application and infrastructure stack as well as enable proactive alerting.

Components that will be auto discovered includes:

  • Concurrent Processing Node
  • Workflow Manager
  • WebLogic
  • Forms

Today, Stack Monitoring service supports EBS version 12.1 and 12.2 deployments hosted on OCI, On-Premise or Third Party Cloud (eg. AWS, Azure). 

In the example, I will show you how you can configure Stack Monitoring for EBS version 12.2.

Agents for Observability & Management

To use Observability & Management (O&M) services, there is the option to deploy OCI agents depending on which service you wish to enable.

There are two types of agents that can be used.

  1. Oracle Cloud Agent (OCA) – This agent is deployed by default if you provision hosts via the OCI Compute Service. OCA has extensions and plugins which can be used to enable other features native to OCI Compute Services.
  2. Management Agent (OMA) – This agent is a standalone version where you can deploy to hosts or VMs:
    – That do not have OCA installed on OCI eg. OCI Database Services (eg. Oracle Base VM/BM, ExaCS).
    – On-Premise
    – Third Party Cloud (AWS, Azure etc..)

Please see the current O&M support we have for each agent:

TLS Migration – A better way

HTTPS is essential as it protects the privacy of our data over the Internet. W3’s 2022 report shows nearly 80% of all websites use HTTPS as their default web protocol, up 6% on the previous year.

Getting started with HTTP/TLS is fairly straightforward. Obtain a CA signed certificate, configure it on your web servers and reverse proxy load balancers and you’re good to go. But how do you ensure your configuration stays up-to-date with current industry standards?

CyberSecurity is an arms race. As hardware and software evolves, so do the tools and techniques created to exploit them. This fierce race largely drives the innovation that we see in the industry today.

How does this relate to TLS? Since the inception of SSLv1 by Netscape in the 90’s there’s been many revisions, SSLv2, SSLv3, TLSv1.1, TLSv1.2 with the current version being TLSv1.3. TLSv1.1 was deprecated in 2021, with new versions being released approximately every 5 years. Given the rate at which exploits are discovered these release cycles will also need to keep pace.

For organisations this poses a number of interesting challenges because you can only control what TLS versions you support. Also if your website or API is public then it’s likely you have no control over the connecting client, or which TLS versions they’re able to use.

A Better Mechanism for Periodic Functions Invocation?

Functions in Oracle Cloud Infrastructure are great. As a serverless execution environment with pre-built logging, metrics, etc. it allows developers to simply focus on their code and not worry about all of the supporting infrastructure, while still providing a lot of flexibility through the use of container primitives. As great as Functions are, they are reactive, they can only be invoked and can’t natively be configured to be executed in a spontaneous or scheduled manner. Often this won’t matter, as Functions will be invoked directly or indirectly by users, or in response to events, but sometimes you simply need a bit of code to run periodically.

CI/CD working with EiPaaS Oracle Integration (OIC)

Everyone is aware of the continuous integration and continuous development relevance which is nowadays the mantra of DevOps practices.

Oracle Integration is obviously part of the end2end lifecycle development being involved for connecting legacy applications usually deployed on-premise and SaaS applications often provided by Oracle Cloud or hosted on other Cloud providers.

It doesn’t matter where the applications are, where the integration is; the continuous delivery of new integration processes and versions need to be included in a smart and automated tool able to reduce the gap between the different developer teams.

Developers, who have the ownership to build new services and IT Operators, who have the task of deploying new code versions to the different environments, need to converge on one single tool to simplify complex procedures that can be simply considered as two sides of the same coin.

The common need is to keep all environments aligned with the latest implementations, possibly having everything monitored and tracked to grant audit activities in terms of compliance; this is a must when the project is starting to become critical and relevant at the enterprise level.

Oracle Integration (OIC), as you know, includes Visual Builder Cloud Service which allows open-source standards-based integration to develop, collaborate on, and deploy applications within Oracle Cloud.

Just for this, it’s easy to use Visual Builder Studio, the built-in tool, that allows developers to manage the software life cycle automating the development.

Oracle VB Studio natively supports Oracle Integration artifacts, so we can leverage this one to easily promote our integration flows from an environment to another one moving for example our integration projects from development to test environment once you we completed the new implementation and of course ready to test it.

That’s the right path to be used for promoting projects from Test to Production or from Production to a DR environment, this one probably running on a different OCI Region.

Working with the current implementation you can:

  • Export integration flows
  • Import integration flows
  • Delete integration flows

As shown below in the picture, the options we have working with Oracle Visual Builder Studio and OIC

Herewith an example of pipeline that you can easily configure to automate the Export / Import procedure and defining in cascade all steps (“jobs”) to define the required actions, of course this one below just for demo purposes. This procedure will be later explained step-by-step just in case you want to reproduce this one for your own purposes

In order to export our assets from the development environment, for example, it’s enough to configure our source and target environments about the OIC instances

How to configure our OIC environments?

This is a straightforward operation working with VB Studio, as shown below:

We can create all connections we need to configure properly the tool

Once we have configured our instances, we need to build our “pipeline” so to automate the procedure when needed

Each pipeline can include all “jobs” we need (in the previous screenshot we have used two different jobs “select your OIC project” and “import OIC project”) so to build the right chain among the different available “jobs”

To create a job, select the Build link from the left panel of the Visual Builder studio and then we can create a new job

Each job has some options and parameters to be configured as below the screenshot shows:

Select the “Parameters” tab to configure the string parameter:

The “Default Value” is the value of the integration flow version on our OIC instance to be selected and moved to the new instance. Of course, this value can be changed when we run the build so to properly set the right integration flow version

Now it’s time to select the “Steps” tab to identify the OIC instance from where we want to export our integration flow

If needed, we can also include the asserter recording just flagging the box. In this case we are moving (exporting / importing) the integration flow named “ECHO” and working with its *.iar file once we have exported this one.

Now you can click the “After Build” tab to configure it as below described. The *.iar extension is the default extension of the integration flow when you decide to download it.

Click save and that’s all. Our first job is properly configured now.

To proceed we are now ready to configure the second job (“import OIC project”).

In this case, the first step to be accomplished is the configuration of the “Before Build” tab as below shown and adding a “Copy Artifacts” option

And now, as we did with the first job, we can properly configure the OIC instance target, in our sample, but in this case for the import action.

We can also check the box about the “activate integration” option so that our integration flow will be imported and started just to have this one ready to be invoked by applications

Also, in this case, we can now save our configuration.

Once these operations have been completed, we are ready to test our pipeline selecting the start button on the right side of the web page and below shown

If the execution of our “build” is properly configured, we can see the “green flag” of our jobs once we run it

Furthermore, we can drill down the execution to look at the log information just in case something wrong having also the chance to download the file including the log for further analysis or if we need to share this one with other people or applications.

From the Visual Builder Studio “Home page” we can also get information about statistics and previous executions so to track the activities managed on the different resources we have

This is for sure the best way to properly manage our environments and the best approach to have under control the lifecycle of our projects and their deployment.

#BuildWithAI 2021 – Another Step

Last weekend (from Friday 29th Oct to Tuesday 2nd Nov), was the #BuildWithAI Hackathon 2021 where participants, mentors, sponsors and organisers gathered together to solve real world challenges with AI. This event does not standalone. In a world full of change, this (from my perspective) started last year in the #BuildWithAI Hackathon 2020 and continued to build.

This article is about the event but the event itself is just “Another Step”.

AWR Data Warehouse Repository using Autonomous Database

In Oracle Enterprise Manager (OEM) there is the ability to host an AWR Data Warehouse which enables you consolidate all your detailed performance data of all your database and store in a central location.

This enables you to do long-term analysis trend across your AWR data to determine, performance, capacity impact on the databases in your IT estate.

In OEM 13.5, Oracle now supports the AWR Warehouse repository for Autonomous Data Warehouse.

If you don’t have the infrastructure or capacity to store AWR data on-premise, you can now send your data to the Autonomous Data Warehouse (ADW) in Oracle Cloud (OCI).

There are enormous benefits to using Autonomous Data Warehouse (ADW). One of many benefits is that you can scale up/down cpu and storage whilst the database remains online.

Ingesting Logs into OCI Logging Analytics (via Agent Based Deployment)

Logs are often voluminous can be challenging to navigate through, but it can be a gold mine of valuable data to help administrators troubleshoot and identify issues or trends for operational activities.

To overcome the burden of manually eye-balling millions or (even billions) of rows in log records, bringing that data into OCI Logging Analytics (which is part of the Observability & Manageability Portfolio) will allow administrators to get quick insights, to reduce the time to isolate issues, minimising downtime and prevent impact to end users.

Using OCI Bastions with PuTTY

Recently, Oracle rolled out the OCI Bastions service, which is designed to simplify the process of accessing instances which do not have a public IP address. They are really easy to use, with simple commands to allow access to these internal hosts… if you are using a Unix shell. Unfortunately I suffer from being quite wedded to various tools, and as a Windows user, I tend to use PuTTY to access hosts via SSH, so this blog post will detail both the OCI Bastion service in a little more detail, as well as how I continued to resist changing my old habits, and set up connections using the OCI Bastion service using a number of components of the PuTTY suite of tools.
