In previous part 1 blog, we demonstrated how to connect Lego EV3 to Azure IoT hub through MQTT, and send EV3 color sensor data to IoT hub. In this blog, we will experiment to update Azure Function which we built on blog “Azure IoT integration with Maximo — Part 2” to create work order in Maximo through Maximo NextGen Rest API based on the color sensor data sent from Lego EV3. ...

IoT (Internet of Things) is getting more and more popular in the world, especially when 5G technology was rolled out to our real life and industries, more and more IoT use cases were adopted in different industries. In the following content, I would like to introduce a POC to leverage IoT technology in EAM (Enterprise Asset Management) area. IBM Maximo is the major player in EAM market, and Azure IoT is the most popular IoT platform, In this POC, I would introduce how to integrate Azure IoT platform with Maximo through Maximo NextGen Rest API. The purpose of this POC is to demonstrate sending IoT device sensor data (for example, temperature data) to Azure IoT hub, through Azure Event Grid to pass telemetry to Azure Function. In Azure Function, call Maximo NexGen Rest API to post telemetry data to Maximo Asset meter reading. The following is the high level of the architecture diagram: ...

In the previous part 1 blog, we built Azure IoT Hub in Azure cloud, developed an IoT device simulator running in local machine to connect and send ramdom temperature data to Azure IoT Hub , created an Azure function, and configure Azure event grid to pass through Azure IoT Hub telemetry data (temperature) to Azure Function. In Azure Function, we parsed event data to retrieve device and temperature information from event data and log them. In this part 2 blog, we will continue to configure and build the rest of the components inside the red rectangle in the following architecture diagram. ...

Docker becomes more and more popular in the development process, especially for the organization adopting DevOps process. I have couple projects require to use docker to build local development environment. My local hard disk space started to getting red after 2–3 rounds of rebuilding local docker environment for different branches of the code change. I did run rm command to remove containers, images and volumes. Since Docker Desktop for Windows uses WSL to manage all the images and container files and keeps them in a private virtual hard drive (VHDX) called ext4.vhdx. This vhdx will not automatically shrink when you remove docker, images or volumes. You need to follow the below step to shrink it. ...

Yes, I am still working on BIRT report as fire fighter for one of my projects. Now was into another tricky issue. The BIRT report I am helping on looks all good except when try to export it to PDF. Some particular page the content cross the footer, such as below: Tried different options, such as setting page break, modified padding of the row. But none of them solved this issue. Tried asked MR. Google, but didn’t find any useful solution on it. The client can accept to move the paging number to the top, but it will require to update the master page template, and I thought it is not a good solution as well. I can understand this should be caused by pdf export function on calculating the page content might be different with how BIRT report, but cannot figure out which setting might cause the problem. ...

If you read my previous blog, you might know I am recently working as fire fighter on Maximo BIRT reports. One of requirement on a complicated report is required to retrieve number inside parentheses from long description, for example, need to get (2) from the following long description content: (2) this is long description text, might content rich text format The solution in my mind when I heard this requirement is to use regular expression. Since in current project the Maximo database is DB2, asked Mr. Google to found DB2 did support regular expression in the query. After looked up regular expression functions on DB2 document, REGEXP_INSTR function is what I need. For example, if you run the following query: ...

2 years ago was working on developing Maximo BIRT report in client laptop, which was installed firefox browser by default. There was not issue when I installed and configured BIRT report development environment at that moment. Recently in my project one of the my team member was on paternity leave, I had to roll up my sleeve again to pick up the a BIRT Report he was working which was required hard deadline (Firefighter is always my other role in the projects). Followed the instruction to install and configure my local BIRT report development environment, everything was good until tried to run the report in Eclipse, got the following error: ...

In Maximo, there are a lot of system default property for different purposes. You can define your own property in System Properties Application, which can be used in your customized script code, configuration, or Maximo Integration Framework (MIF). As default setting, you cannot change the value for system default property. For some special scenarios, you might have to change the system property default value. To be able to modify system default property, the following instruction will provide an example on how to change the property: mxe.int.binarytext ...

Recently encountered a pretty strange issue when tried to release an simple Maximo workflow to production environment. The workflow is to allow business team (Maximo Support team) to review new service request, to decide to create related work order, or cancel service request. The following is the workflow diagram: This workflow is working fine in testing environment. When we implemented the same workflow in production, doing the production check-out: created a new SR, attached it to this workflow, started the workflow, got the error message: BMXAA4299E ...

For Maximo integration with external system, there are two directions from Maximo’s perspective: Inbound and outbound interfaces. There is a lot of business scenarios for the requirement of query data from Maximo, which we consider it as outbound interface for Maximo. For example, external system ServiceNow might need to query service request data in Maximo to pull out the service request current status. There are couple ways to query data from Maximo. Maximo support Web Service and Restful. The return result can be xml or json format. In this article, will show you how to leverage Maximo Restful API to query data in Maximo. ...
