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.
You can either create a private SERVICES file or update the system SERVICES file
(usually $SYSTEM.ZTCPIP.SERVICES) with lines such as
A private SERVICES file is an edit file located in the same subvolume as the installed
ASYMON object file. Refer to $SYSTEM.ZTCPIP.SERVICES for a sample file.
AutoSYNC searches for the SERVICES file in the following order:
1. A SERVICES file in the AutoSYNC product subvolume.
2. A file specified by an =TCPIP^SERVICE^FILE define. The define must be specified

when Autosync CI is started for one-time synchronizations,

when the monitor is started for scheduled synchronizations.
3. The file $SYSTEM.ZTCPIP.SERVICES.
The ASYSYNC-ZASY port
The ASYSYNC process on the source system uses the SERVICES file or define to
connect to the monitor on the destination system.
The monitor process on the destination system uses the SERVICES file or define to
create a TCP/IP listener.
The define is specified in the TACL session that starts an AUTOSYNC CI process. For
a monitor process, it is the define set when the START MONITOR command is issued.
ASYSYNC-ZASY <port-num>/tcp # AutoSYNC
and optionally
ASYNCLOG-ZASY <port-number>/tcp # AutoSYNC LOG
Note. The entry in the SERVICES file is case sensitive; the service name must be entered in
uppercase, the keyword tcp in <port-num>/tcp must be in lower case. This is a TCP/IP
requirement.
