Autoconfig as name suggests is automated configuration of Oracle Applications 11i. Well if this is configuring oracle applications 11i question comes from where its getting configuration information. File from where Autoconfig runs picks parameter to configure 11i , in Oracle's terminology is called Context File. Power of configuring whole applications via this single file (One for Application Tier & other for Database Tier) makes this file quite powerful. Rest all I discuss in terms of questions answers or FAQ format about Autoconfig.
