It will be convenient to obtain actual attributes of DB when its state is backup-lock.
Currently such actions as 'gfix -w sync | async' or 'gfix -h <sweep_interval>' do not reflect on gstat -h:

It is easy to check if we first do 'nbackup -L <dbname>' and then:

1) check current header:

#⁠ /opt/fb30/bin/gstat -h /home/bases/oltp30-etalone.fdb | tail
Creation date Apr 3, 2020 16:41:55
Attributes force write, backup lock

Variable header data:
Sweep interval: 0
*END*
Gstat completion time Wed Sep 9 10:32:54 2020

2) try to change FW (or sweep interval; or page buffers - no matter):

#⁠ /opt/fb30/bin/gfix -w async localhost:/home/bases/oltp30-etalone.fdb
#⁠ -- no output, i.e. all OK --

3) read DB header again:

#⁠ /opt/fb30/bin/gstat -h /home/bases/oltp30-etalone.fdb | tail
Creation date Apr 3, 2020 16:41:55
Attributes force write, backup lock

Variable header data:
Sweep interval: 0
*END*
Gstat completion time Wed Sep 9 10:33:17 2020

In this example "force write" attribute remains unchanged. But is *was* changed and this can be seen when querying mon$database table.
So, one need to connect and to ask monitoring to get actual value of this attribute.
