Hi,
I need some help regarding the information shown in available.log
It indicates that our server is unavailable since the day it was started
[Unavailable 07.06.2007 20:48:54 - 19.09.2007 09:54:08]
But, the XI server works fine.
Currently, the server usage is not that intense. Will there be any issue because of what is indicated in the available.log? Will the behavior be inconsistent and unpredictable?
Thanks!
Hi,
'available.log' is written by the SAP service sapstartsrv.exe. The
service checks the status of the actual process list
(like you can see in in the MMC SnapIn under the "Process List" node).
If all processes are "green" the instance is considered to be available
otherwise not. Since the status information of the Dispatcher is
calculated from multiple parameters (process running + connected to
message server + shared memory available + good dialog queue time)
the information in available.log is very reliable.
The information is checked and updated every 60 sec and at instance
startup and shutdown. The default threshold for a "good" dialog time
is 5.0 sec. You can adjust this threshold with the profile parameter
max_dia_queue_time in the default or start profile (service must be
restarted after changing it).
If the service notices that the last update to available.log is older
than 60 secs (e.g. due to computer shutdown), it will always start
a new line in available.log
No SAP application reads available.log it is just a simple logfile
to protocol system availability.
Award points if helpful.
Thanks,
Tanuj
