Administration Listening Port |
3702 |
Identifies the listening port that the subscriber uses to monitor administrative requests from Operations Console. |
Number of packet buffers |
5000 |
Identifies the number of packet buffers. The subscriber 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 subscribers, a value of 500 will usually provide sufficient buffering to handle small bursts of high-volume data. |
Number of packets tracked |
5000 |
Identifies the number of packets the subscriber tracks. Subscribers track the packets delivered by a publisher. If a subscriber suspects that a packet may be missing, it issues a resend request to the publisher to retrieve the missing data. The number of packets tracked is for each data stream. |
