Our production set up is having 2 Database cluster and 2 CI cluster and 4 application servers.
the cluster is configured by the SUSE linux 10 Hearbeat,
Our system is ECC 6.0 and Netveaver 700.
please provide me the best order and proper way to shutdown and start the whole system.
Depending to your cluster configuration you must use cluster tools to start/stop resources in the following sequence:
start - db (cluster resource), ci (cluster resource), application servers
stop - application servers, ci (cluster resource), db (cluster resource).
thanks for the quick reply..
I need it to describe. because currently we are doing the above procedure as follows.
I wanted to ensure the way which I follow is correct. its working. but it takes more time to down.
is that ok?
The sequence you have given doesn't look correct to me
If group_CI starts your application server then it should be started after ASCS and ERS. Please note there is nothing like a CI in HA.CI in non-HA is split up into ASCS and Primary Application server. ASCS has message server and enqueue and that got to be running before you start any Primary App or for that matter secondary App;
However if this group_CI is doing any activities that determine ASCS and ERS start up and shutdown then you need to retain those parts and create a new grouo for App servers which be executed in the end for startup and the beginning for shutdown.
A detailed and correct sequence is this:
DB-->ERS-->ASCS-->Primary App--->Secondary Apps
Secondary Apps-->Primary Apps-->ASCS-->ERS-->DB
Hi Ruchit Khushu.
Thank you very much. I correct the the order.
