** [tickets:#2082] CKPT : Track cbk not invoked for section creation after cpnd
restart**
**Status:** review
**Milestone:** 5.18.09
**Created:** Thu Sep 29, 2016 11:06 AM UTC by Srikanth R
**Last Updated:** Fri Sep 07, 2018 11:01 AM UTC
**Owner:** Mohan Kanakam
Changeset: 7997 5.1.FC
Track Callback is not invoked after cpnd restart. Below are the apis called
from the applications , spawned on two nodes .i.e payloads.
On first node :
-> Initialize with cpsv
-> Create a ckpt with ACTIVE REPLICA flag.
On second node.
-> Initialize with cpsv.
On First node,
-> Open the checkpoint in writing mode
-> Open the checkpoint in reading mode.
-> Kill cpnd process
-> Register for Track callback.
On Second node,
-> Open the ckpt in read mode.
-> Kill cpnd proces
-> Register for Track callback.
After ensuring that both agents registered for track callback, create a section
from the application on first node. For section creation, callback should be
invoked for applications on two nodes.
Currently callback is not invoked for the application on second node. With out
cpnd restart, callback is invoked for the two applications
