External user data in Okta Sync with asp.net app Oracle database

Hey I am new to Okta and wish any thoughts/ideas for my new project.
We are using SiteMinder/IdentityMinder for asp.net web application and want to replace them with Okta. The user info( (identifier and company) in Okta needs to be synchronize with application Oracle database for user notification and VPD(Oracle virtual database). My question is : what is the best practice to implement this feature?
Thanks in advance.
