Oracle Enterprise Manager 12c Release 3: What’s New in EMCLI

If you have been using the classic Oracle Enterprise Manager Command Line interface ( EMCLI ), you are in for a treat. Oracle Enterprise Manager 12c R3 comes with a new EMCLI kit called ‘EMCLI with Scripting Option’. Not my favorite name, as I would have preferred to call this EMSHELL since it truly provides a shell similar to bash or cshell. Unlike the classic EMCLI, this new kit provides a Jython-based scripting environment along with the large collection of verbs to use. This scripting environment enables users to use established programming language constructs like loops (for, or while), conditional statements (if-else), etc in both interactive and scripting mode.

Benefits of ‘EMCLI with Scripting Option’

Some of the key benefits of the new EMCLI are:

  • Jython based scripting environment
  • Interactive and scripting mode
  • Standardized output format using JSON
  • Can connect to any EM environment (no need to run EMCLI setup …)
  • Stateless communication with OMS (no user data is stored with the client)
  • Generic list function for EM resources
  • Ability to run user-defined SQL queries to access published repository views
