Start and Shutdown Sequence
SAP Java–based systems will start in the following sequence:
1. Database is started.
2. Central services instance is started (Java message server and enqueue server).
3. Central instance is started (Java dispatcher, server process, and SDM).
4. Dialog instances are started (Java dispatcher and server process).
The shutdown sequence is the exact opposite of the startup sequence.
When the startsap command is issued, it will start the Java startup and control framework. It is the responsibility of the startup and control framework to start the rest of the components and processes of the SAP Java cluster. The startup and control framework is a little different in NW 7.0 and NW 7.1 releases. We will study both here.
