Synchronization Over TCP/IP
Overview
AutoSYNC supports the use of a direct TCP/IP network connection to communicate
between the source and destination AutoSYNC processes. Configuration and use of
TCP/IP does not interfere with the concurrent use of Expand to synchronize files. A
single AutoSYNC installation uses both networks as requested by the user.
The advantages of TCP/IP are:
•
You may synchronize files between systems that have the same Expand system
name or number. Expand will not allow such systems to coexist on the same
Expand network, but two systems can be configured with identical names when
upgrading from one system to another.
•
Development and test systems may not be connected to the production Expand
network, but you may still wish to transfer files between them.
•
Direct TCP/IP connections may be more efficient than Expand connections that are
based on TCP/IP. Also, you may wish to avoid contention for the network
connections that are being used for Expand.
Configuring a TCP/IP connection
Some configuration steps are required only on source systems, other steps only on
destination systems, and others on both systems.
On both Source and Destination Systems
Set the TCP/IP port numbers for AutoSYNC
A TCP/IP SERVICES file is used to specify the port number for use by defined
services. The name of the service is ASYSYNC-ZASY where ZASY is the name of the
AutoSYNC monitor process $ZASY that is used on both systems to coordinate the
TCP/IP connections.
Optionally, you can also configure an additional port that will be used by AutoSYNC to
send log records from the destination synchronization process to the source
synchronization process. The name of the log service is ASYNCLOG-ZASY. If the
ASYNCLOG-ZASY is not explicitly configured (the default), the port used for logging is
chosen by TCP/IP from a pool of unassigned port numbers.
