AUTOLOG considerations

If a procedure in the AUTOLOG list also has a PORT statement reserving a TCP or UDP port but does not have a listening connection on that port, TCP/IP periodically attempts to cancel that procedure and start it again.

Guideline: Do not use AUTOLOG to start the Policy Agent if any listening connections are used. The Policy Agent is unlike typical servers, and performs functions outside the realm of listening for connections from other applications. Sometimes during normal operation of the Policy Agent, listening connections are unavailable for short periods of time. When listening connections are unavailable, it is possible that the AUTOLOG timer could restart the Policy Agent.

Policy Agent optionally listens on one or more of the following ports:

The pagentQosListener port (usually defined in the /etc/services file as port 1700). This happens only when the PolicyPerfMonitorForSDR statement is configured for a given TCP/IP stack.
The port defined or specified by default on the ClientConnection statement, which is used to listen for remote policy client connections on all TCP/IP stacks.
The port defined or specified by default on the ServicesConnection statement, which is used to listen for services requester connections on a single TCP/IP stack. For information about the ServicesConnection statement and specifying which stack to use to listen for these connections, see z/OS Communications Server: IP Configuration Reference.

If you want to start Policy Agent with AUTOLOG, you must take one of the following actions:

Ensure that none of the listening ports used by Policy Agent are reserved by the PORT statement in the TCP/IP profile.

Add the NOAUTOLOG parameter to the PORT statement in the TCP/IP profile. For example:

PORT 
 1700  TCP PAGENT NOAUTOLOG
 16310 TCP PAGENT NOAUTOLOG
 16311 TCP PAGENT NOAUTOLOG

In addition, when the PolicyPerfMonitorForSDR statement is being used, if the pagentQosCollector port (usually defined in the /etc/services file as port 1701) is reserved in the PORT list it should always be specified with the NOAUTOLOG parameter, because this port is never used as a listening port. For example:

PORT 
 1701 TCP PAGENT NOAUTOLOG

Tip: When Policy Agent is not listening on any ports, you can use the autostart feature of AUTOLOG as previously described. However, the monitoring and automatic restart features of AUTOLOG are unavailable because AUTOLOG must listen to a TCP or UDP connection.

If you fail to take one of the above actions, Policy Agent will be periodically canceled and restarted by TCP/IP.
