Problem:

  • Product Name: VisiBroker for C
  • Product Version: 5.1, 6.5 or later
  • Product Component: QoS timeout policies, LIOP communication
  • Platform/OS Version: HP-UX 11.0

Can we have QoS timeouts for shared memory?

Resolution:

Whenever QoS timeout is set, the client orb uses unix domain socket instead of shared memory (LIOP consist of unix domain socket and shared memory in platforms like AIX and HP, but only one LIOP scheme is active at any one connection). Since the unix domain socket is using socket APIs, the timeout mechanism works exactly like IIOP.

However, there are no provisions in the Operating Systems kernel to support timeouts in shared memory. Hence, timeouts with shared memory cannot be implemented.
