Objective

In this exercise you will trigger the application of LANSA Patches to all the Web Server instances. As it is an exercise you may do this at any time, but with a production system you would schedule a time to perform this maintenance activity and take the application offline and perform tests to ensure your application is still working as expected.

The AWS Console status will change to UPDATE_COMPLETE when the FIRST part of the process is complete. That is, it's updated the definition of the stack. The actual action you have requested is not started until the next time the agent on the EC2 instance checks for changes. This occurs at 1-minute intervals. The action must then be executed. How long the action takes to execute depends on what you have asked it to do. It may take many minutes.

Also, only apply one trigger at a time and allow sufficient time for the action to complete before applying another trigger.

To achieve this objective, you must complete the following:

Step 1. Select Stack to Update

Step 2. Specify Details

Step 3. Check that the patch has been Applied

Summary

Before You Begin

You must have completed the following exercises:

CTE040 – Create the LANSA Stack

CTE010 – Upload your LANSA Web Application (but to upload your patches)

CTE060, Step 1. Disable the Load Balancer Health Check

The patches for your application must have been uploaded already. You can follow the same procedure as explained in CTE010 – Upload your LANSA Web Application but instead of uploading the MSI, upload the patches. The same S3 folder should be used as was used for the MSI.
