Usage Note 58546: Controlling which TCP/IP ephemeral ports SAS®9 uses under z/OS
SAS® products that perform network communications use TCP/IP ephemeral ports. These ephemeral ports are generally used within the host domain that they are allocated in and are not required to be open on a firewall.
Here are some SAS components that use TCP ephemeral ports:
- The FILENAME FTP engine opens the FTP client port
- The FILENAME EMAIL engine uses the ephemeral port
- Spawner environments such as SAS/CONNECT® and SAS® Integration Technologies Object Spawner use ephemeral ports
- The SIGNON statement opens the SAS/CONNECT client ephemeral port
If you must control the ports used under z/OS, set all of the following TK environment variables in the TKMVSENV file
that is allocated by the SAS session:
set TCP_EPH_MAP_ENABLED=1
set TCP_EPH_MAP_FIRST=beginning-of-port-range
set TCP_EPH_MAP_LAST=end-of-port-range
Beginning in SAS® 9.2, the default setting is TCP_EPH_MAP_ENABLED=1.
Note: You can control the ephemeral port used for the SAS/CONNECT Spawner SASDAEMONPORT option by specifying the -SASDAEMONSERVICE parameter in the PARMS file.
