GRID architecture
192 Sybase IQ ETL 4.1
Communication
The server instances are using UDP broadcasts in order to inform other nodes
about urgent events, such as start and stop, as well as system failure or crash
immediately.
The default port for communication is port 5124. You can change this in the
INI file or on the command line.
All communication between the nodes is done over TCP/IP on the same port.
Note Verify that you have no firewall blocking this port or change the port on
all server installations to a different number better matching your environment.
Using the server
The server application can behave in several different ways, depending on the
parameters provided.
• GRID Engine Server — the GRID Engine with start in server mode,
waiting for execution requests.
• GRID Engine System Service — the GRID Engine can be installed as a
Unix Daemon or Windows System Service and works as a GRID Engine
Server.
GRID Engine Server
A GRID engine running as a server is waiting for execution requests through
TCP/IP. The default port is 5124 and can be customized.
