------------------------------------

[~hshreedharan]

So ur saying basically .. during FC close

- set the open=false first
- grab the exclusive lock first (since it is re-entrant)
- write a checkpoint
- proceed with closing ..


is that right ?

> Add option to checkpoint on file channel shutdown

> Restarting a File channel based agent can take very long, a few hours to 
> evens days in some cases. The reason being the slow replay performance.
> By having the file channel checkpoint on shutdown, this long replay can 
> avoided as there will be nothing to replay on startup.
> A small hit (a few seconds perhaps) will be observed on shutdown to perform 
> the checkpoint.
