Recently at a hackathon we used the Pivotal MySQL service rather then a ClearDB MySQL service. As a result we could not connect to our instance from a third party tool as the service instance is locked down. There are various way to access the MySQL service to me the best two options are as follows.1. Cloud Foundry CLI MySQL Plugin
cf-mysql-plugin makes it easy to connect the mysql command line client to any (more...)
Was involved in a hackathon recently and after creating a few Spring boot API's for the UI team to consume and they run into errors around (Cross-origin resource sharing ). For security reasons, browsers prohibit AJAX calls to resources residing outside the current origin.
I have seen this before and Spring Boot has support to ensure you can control which resources can be accessed outside of the current origin. It's as simple as an annotation (more...)
R = REST
E = Express
N = Node.js
O = (Node)OracleDB
I've read am article about an REST Api with Node.js and Node-OracleDB at the website of Amis
and at the website of Sivakumar Balagopalan
This inspired me to write a application on the employee table inside the HR schema. The url http://machine:3000/employees fetches all rows in the employees table.
The url http://machine:3000/employees/200 fetches the employee with employee_id 200 from (more...)

I previously blogged about the Pivotal Cloud Cache service in Pivotal Cloud Foundry as followshttp://theblasfrompas.blogspot.com.au/2017/04/getting-started-with-pivotal-cloud.html
During that post I promised it will follow with a Spring Boot application which would use the PCC service to show what the code would look like. That demo exists at the GitHub URL below.https://github.com/papicella/SpringBootPCCDemo
The GitHub URL above shows how you can clone , package and then push this application to PCF (more...)
In the last few years, business problems that have been traditionally solved using databases are now being solved using other technologies. Apache Spark is one of the emerging technologies which is used for large scale data processing.Attend the free webinar by Ivan Lokic and learn how you can use Apache Spark in Big Data applications.

Recently we announced the new cache service Pivotal Cloud Cache (PCC) for Pivotal Cloud Foundry (PCC). In short Pivotal Cloud Cache (PCC) is a opinionated, distributed, highly available, high speed key/value caching service. PCC can be easily horizontally scaled for capacity and performance.
In this post we will show how you would provision a service, login to the Pulse UI dashboard, connect using GFSH etc. I won't create a spring boot application to use the service (more...)
Pivotal Cloud Foundry (PCF) has various cloud service brokers for all the public clouds we support which include AWS, Azure and GCP. You can download and install those service brokers on premise or off premise giving you the capability to use Cloud services where it makes sense for your on premise or off premise cloud native applications.https://network.pivotal.io/
The three cloud service brokers are as follows:
In the example below we have a (more...)
Pivotal Ops Manager has various errands in runs for different deployments within a PCF instance. These Errands can be switched off manually when installing new Tiles or upgrading the platform, in fact in PCF 1.10 the errands themselves will only run if they need to run making it a lot faster.
Below I am going to show you how you would manually run an Errand if you needed to on a PCF instance running (more...)
