Linux system to report on the domain so that it can notify that system of the
removal. Use the FORCE option to remove a down domain from ASAP on the
NonStop server when the domain is no longer known on the Linux side.
Domains that are up or inactive must be removed from the Linux system prior to
being removed from ASAP on the NonStop server. ASAP on the NonStop server
does not notify ASAP on Linux when up or inactive domains are removed; it
assumes that the Linux side no longer has knowledge of the domains. If the
domains are not removed from the Linux system first, they will be reregistered
and processed normally by ASAP on the NonStop server when the next sample is
received from that Linux system. For more information on manually removing
domains on Linux, see Cleaning Up Domains Interactively.
There is a rare case wherein both ASAP Hybrid on NonStop and on Linux could
no longer know about a domain, but ASAP Server continues to report on the
domain. This situation can occur if the Linux system or network fails and then the
Hybrid Gateway process is stopped or fails. When a domain does not appear
anywhere in ASAP Hybrid but does appear in ASAP Server, the ASAP MONITOR
command must be used to remove the domain.
Important Note: Using the ASAP MONITOR command to forcibly remove a
domain registered with ASAP Hybrid (MONITOR <entity>, REMOVE, FORCE) can
cause the Hybrid Gateway process to abnormally terminate as its memory is
taken away. It will recover and continue to operate normally after the
termination, but the MONITOR <entity>, REMOVE, FORCE command should be
used only in extreme circumstances when there is no other way to manually
remove an ASAP domain.
