create application-server relationship

[brahmandlapally]

When a new server is provisioned, the 'Application' name from the new server request RITM should be populated to the 'Hosted Application' field for the new server CI record in CMDB.

Also, the Application mentioned in the RITM should have 'Runs on' relationship to that new server.

Hi @brahmandlapally 

To populate the 'Hosted Application' field and create a 'Runs on' relationship for a new server in ServiceNow:

1. Create a Business Rule on the cmdb_ci_server table.
2. Script Logic:
   • Fetch the associated RITM using a custom field (u_ritm).
   • Retrieve the Application from the RITM (u_application).
   • Set the 'Hosted Application' field with the Application value.
   • Create a 'Runs on' relationship between the Application and the new server.

This ensures the application is linked to the server CI and the relationship is automatically established.

Thank you

Hi @brahmandlapally 

To achieve the desired functionality in ServiceNow, where the 'Application' name from a new server request (RITM) is populated into the 'Hosted Application' field for the new server CI record in the CMDB, as well as establishing a 'Runs on' relationship between the Application and the new server, you can follow these steps:

Steps to Implement        

Create a Business Rule:
   - Navigate to System Definition > Business Rules.

   - Click on New to create a new business rule.

   - Set the conditions to trigger this rule when a new server request is created.

   - Script to Populate Hosted Application

Configure Application Relationships:
   - Ensure that your applications are defined as Configuration Items (CIs) in the CMDB.

   - Validate that the 'Runs on' relationship type exists in your system.

Testing:
   - After implementing the business rule, test by creating a new server request and verify that:

   - The 'Hosted Application' field is correctly populated.

   - The 'Runs on' relationship is established between the new server and the application.

Error Handling:
   - Consider adding error handling within your script to manage any issues during the creation of records or relationships.

Thanks, and Regards

Hi @brahmandlapally 

To achieve the automation of populating the 'Hosted Application' field and creating a 'Runs on' relationship between the server and the application in the CMDB when a new server is provisioned, you can implement this process using ServiceNow or similar ITSM tools. Below is an overview of how this can be accomplished, especially if you are using ServiceNow:

Steps:

1. Create Business Rules: A Business Rule can be set up to run when a new Server CI is created and link the Application from the RITM to the Hosted Application field in the Server CI record.
2. Script to Update 'Hosted Application' Field: Write a script within the business rule that:

• Retrieves the Application from the RITM (Request Item) when a new server is created.
• Updates the Hosted Application field in the Server CI with the retrieved application name.

1. Create a 'Runs on' Relationship:

• A separate script can be added to create a CI Relationship (Application to Server), where the application Runs on the newly provisioned server.

Example for Configuration of servicenow:

Step 1: Business Rule to Update the Hosted Application Field

Trigger: After Insert

Table: cmdb_ci_server

Script:

// Assuming RITM holds a reference to the application, you would need the RITM's sys_id or some identifier.
var ritm = current.variables.request_item; // Assuming request item holds the RITM reference
var ritmGR = new GlideRecord('sc_req_item');
if (ritmGR.get(ritm)) {
var application = ritmGR.u_application;
current.u_hosted_application = application;
current.update();
}

Step 2: Create a Relationship Between Application and Server

Trigger: After Insert (can be part of the same business rule)

Script:

var relationship = new GlideRecord('cmdb_rel_ci');
relationship.initialize();
relationship.parent = current.u_hosted_application; // Application CI
relationship.child = current.sys_id; // New Server CI
relationship.type = 'Runs on::Runs'; // Relationship type
relationship.insert();

With this setup, the 'Hosted Application' field in the new Server CI will be automatically populated, and a Runs on relationship will be created between the Application and Server when a new server is provisioned from a RITM request.

What is the process of new server is provisioning? 

[brahmandlapally]

end user will request new server built request through catalog item form one of field in form should get populated in new server CI record 

[Saurabh Gupta]

Hi,
How a newly created server linked to the RITM/related task created from the catalog?

[Dr Atul G- LNG]

So you want , as soon as the Server CI get created and user selects Application and click on submit, the relationship get created?
