# Scenario 7: Deploy an emergency fix

This scenario demonstrates how to apply a quick solution by making an emergency fix.

Note: To run this scenario, first set up the environment, as described in Prerequisites.

In this topic:

## Scenario overview

After an update to the Qlarius Health Insurance corporate website, a defect is found that prevents the site from being used by the customers. Rolling back to the previous version is not a solution, as changes were introduced that the company does not want to lose.

- The release manager raises a Dimensions CM change request to track the defect.

- The development team lead primes a task from the request.

- A web developer fixes and delivers the defect, and relates it to the task.

- The team lead promotes the request and task to the PRE-PROD stage.

- The release manager deploys the request and task to the PRE-PROD deployment area, and then promotes and deploys them to the LIVE stage and production environment.

The team lead does a peer review and actions the task to its final state. | Ted has read his email, seen the task in his Request inbox, done a peer review of the file that Wendy modified, and is satisfied with the changes that she made. He actions the task to its final state, CLOSED. Log in to the web client as Ted. In the Requests tab, select the Request inbox. Select the child task, and in the toolbar select Action. The Action wizard opens. Check that the To Next State field is set to CLOSED. Click Finish and click OK. The task is removed from Ted’s request inbox.
The team lead promotes the request and task straight to the PRE-PROD stage. | Because this is an emergency fix that is required urgently, Ted promotes the request and task straight from DEV to PRE-PROD, bypassing the intermediate stages (SIT and QA). The Deploy by Default option is not enabled, so the request and task cannot be automatically deployed to the PRE-PROD deployment area. Select the request. In the toolbar, click Promote. The Promote wizard opens. Check that the Promote Child Requests option is selected. From the Next stage field, select PRE-PROD. Click Next. Because Deploy by Default is not enabled, no deploy options are available. Click Next. Review the summary and click Finish.
The team lead verifies that promotion was successful. | Ted verifies that promotion to PRE-PROD was successful. Select the Deployment view . To view information only for the current stream, click the filter button at the top right of the navigation pane, and select Show Current Stream. Select the History tab. In the navigation pane, select the PRE-PROD stage node. In the content pane, verify that the request was promoted successfully from DEV to PRE-PROD.
The team lead delegates the request to a QA engineer. | Ted delegates the request to Tony, a QA engineer, for testing. In the Requests tab, select the request, and in the toolbar click Delegate. The Delegate wizard opens. Check that the Capability option is set to Secondary. From the Role to Delegate list, select QA ENGINEER, and click Next. In the Candidate Users Authorized for Role Assignment list, select Tony, and click Add. The wizard closes automatically. Dimensions CM sends an email to Tony notifying him that a task has been added to his Request inbox.
The team lead actions the request to its next state. | Ted actions the request to its next lifecycle state, IN TEST, so that the Tony can perform testing.

In the Details of Solution Given field, enter Fixed index.html. Click Finish. The task is removed from Ted’s Request inbox. Dimensions CM sends an email to Tony notifying him that a task has been added to his Request inbox. Log out of the web client.
Let’s assume the following: Tony has tested the website to make sure that the latest revision of index.html fixes the problem. Tao, the QA manager, has closed the request.
The release manager deploys the request to the PRE-PROD deployment area. | Rita, the release manager, checks the Pending tab for the PRE-PROD stage on the Deployment view. Rita sees that the request is ready to be deployed to PRE-PROD. Log in to the web client as Rita. In the Deployment view, check that only the current stream is displayed. Select the Pending tab. In the navigation pane, select the PRE-PROD stage node. In the content pane, from the Show list, select Requests. Select the request, and in the toolbar click Deploy. The Deploy wizard opens. Check that the Deploy Child Requests option is selected. Check that the Deploy Stage is set to PRE-PROD. Click Next. To deploy the request and child task now, check that the Perform Deployments option is set to As Soon As Possible. In the Areas for Deployment field, check that the LCL_PP_JMAIN_AREA01 deployment area is selected. Click Next. Review the summary.Click Finish and then Close. Select the History tab. In the navigation pane, in the PRE-PROD stage node, select the LCL_PP_JMAIN_AREA01 deployment area. In the content pane, verify that the request and child task were successfully deployed to the PRE-PROD area.
The release manager promotes and deploys the request and task to the LIVE stage and deployment area. | Because this is an emergency fix, Rita immediately promotes and deploys the request and task to the LIVE stage and deployment area. In the History tab, select the request. In the toolbar, click Promote. The Promote wizard opens. Check that the Promote Child Requests option is selected. In the Next stage field, check that LIVE is selected. Click Next. To deploy the request and child tasks immediately, check that the Perform Deployments option is set to As Soon As Possible. Deploy by Default is not enabled for the LIVE deployment area. But Rita has the privilege to deploy at the same time as the promotion. In the Areas for Deployment field, select the LCL_LIVE_JMAIN_AREA01 deployment area. Click Next. Review the summary and click Finish. In the navigation pane, select the LIVE stage node. In the content pane, verify that the request was promoted successfully from PRE- PROD to LIVE. In the navigation pane, select the LCL_LIVE_JMAIN_AREA01 deployment area. In the content pane, verify that the request and task were successfully deployed to the LIVE deployment area.
The release manager verifies that the emergency fix was deployed. | Rita verifies that the latest revision of index.html was deployed to the LIVE area. In the My Current Project view, in the navigation pane, expand Deployment Areas > LIVE Stage > LCL_LIVE_JMAIN_AREA01 > Qlarius Underwriter > website. In the content pane, verify that the latest revision of index.html was deployed. This revision has replaced the one that was deployed at the start of this scenario.
Note: After the emergency deployment is completed, the latest revision of index.html goes through the normal testing procedures. If it passes the tests successfully it remains in the LIVE deployment areas.
