Initialization

The initialization component performs all the activity necessary to set up the Server as a service provider. The main tasks of this component are as follows:

• Initialize global programs.
  • Allocate the minimum amount of storage required for proper initialization.
  • Initialize internal control blocks.
  • Set up an error recovery environment.
• Check for the proper operating environment.
  • Check that required modules are available and have the expected authorization.
  • Check for a possible previous failure and try to recover. For example, Cross Memory resources are restricted and may not be freed until an IPL is performed. However, these resources can be identified and reused again. Refer to the IBM® publication titled Authorized Assembler Services Guide.
  • Check that required systems like SMF and RMF are operational.
• Setup the CMS environment. This task makes PC service routines for other address spaces available. These routines are used by SMF user exits for fast data exchange and event notification.
• Prepare and start all other components of the Server.
