Dear all,

     when stopping a r/3 system. the correct sequence would be stopping the application server first (both the dialog and central instances), that is to stop the SAP service. Then we stop the database server, that is to stop the MSSQL service, then only we power off the system. Now my question here is when the r/3 is implemented in a cluster enviroment, in which we have two nodes, say node a for the central instance and node b for the database instance. What is the shut down sequence for it? Use the cluster administrator to shut donn the node first (which node?) then power off the system? Which node has to be shut down first? I am asking this because in a situation where there is black out and the system is running on UPS, and when the UPS run out of charge, it will automatically shuts down the server. So back to the question here, i would like to know the sequence. Please advise.

Regards

The sequence is same,
Becasues the resons for sequences are.
"SAP runs on top of OS and Database"
That means without Database there is no SAP (run), simillerly with out OS there is no SAP or database.
So the reverse of the STARTUP sequence, is the SHUT DOWN sequence.

Regarding node, once the SAP and databse is SHUT DOWN, you can shutdown the NODE in any order you like. (Preferably the reverse order of startup sequence)
