exec/amf.{h|c}
|
|
-------------
|
|
Server side implementation of Availability Management Framework (AMF API).
|
|
|
|
exec/ckpt.{h|c}
|
|

|
|
|
|
|
|
exec/gmi.{h|c}

|
|
using ring topology. Supports extended virtual synchrony delivery semantics
|
|
with strong membership guarantees.
|
|
|
|
depends on cglpoll.
|
|
depends on queue.
|
|
depends on sq.
|
|
depends on list.
|
|
|
|
exec/handlers.h
|
|
---------------
|
|
Functional specification of a service that connects into AIS executive.
|
|
If all functions are implemented, new services can easily be added.
|
|
|
|
exec/main.{h|c}
|
|
--------------
|
|
Main dispatch functionality and global data types used to connect AIS
|
|
services into one component.

|
|
|
exec/mempool.{h|c}
|
|
------------------
|
|
