The Publisher API listens for administrative requests from Operations Console and resend requests. Use this dialog to set different listening ports and performance options.

Administration Listening Port |
3202 |
Identifies the listening port that the publisher uses to monitor administrative requests from Operations Console. These requests can include shutdown, restart, and refresh commands. |
Resend Listening Port |
3203 |
Identifies the port that the publisher uses to resend cached message packets to the subscriber. Publishers maintain a cache of recently sent message packets to ensure that the subscriber processes all message deliveries. |
Number of packet buffers |
10000 |
Identifies the number of packet buffers. The publisher holds onto arriving packets of messages until the packets are processed. The number of packet buffers is per data stream. This setting can have a value between 1 and 4 billion, but the machine must have enough memory to hold the number of packets specified. This setting should be adjusted if resend requests from publishers are failing, because the packet no longer exists at the publisher. For publishers, a value of 10000 will usually provide sufficient packet history to maintain data integrity under moderate loads. |
Number of message buffers |
None |
Identifies the number of message buffers the publisher temporarily stores to track data deliveries. One message buffer is required for each message that is being simultaneously built. This setting can have a value from 1 to 65535, though the machine must have enough memory to hold the number of buffers specified |
