Introduction |

Prior to the MPE/iX 6.0 release, TCP on MPE/iX allowed a maximum
of 4096 connections. An enhancement to the TCP module allows up
to 5600 connections. The version ID of TCP (NET_TCP_VERS
in nmmaint,3) which supports this feature will start with B060.
Configuration through NMMGR |
|
You need to configure the machine to allow it to go up to
5600 connections. The NMMGR screen
for configuring the maximum connections looks like the following:
NMMGR/3000 (B.06.00) Transmission Control Protocol (TCP) Config Data: Y
When Data Flag is "N", press "Save Data" to create the data record.
Command:
Path: NETXPORT.GPROT.TCP
[N] Checksum Enabled (Y For Yes, N For No)
[256 ] Maximum Number of Connections
[2 ] Retransmission Interval Lower Bound (Secs)
[180 ] Maximum Time to Wait For Remote Response (Sec)
[10 ] Initial Retransmission Interval (Secs)
[4 ] Maximum Retransmissions per Packet
[600 ] Connection Assurance Interval (Secs)
[3 ] Maximum Connection Assurance Retransmissions

The field, "Maximum number of connections" can now handle
up to 5600 connections. Before this enhancement the range was 0
to 4096. To reach this screen, "Transmission Control Protocol (TCP)
Config" in NMMGR, do the following:
Go to [ Open Config ]
Go to [ NS ]
Go to [ Unguided ]
Go to [ Netxport ]
Go to [ Gprot ]
Go to [ Tcp ]
After the re-configuration is validated, stop, then restart,
the network to implement the increased TCP connection limit. It
is not necessary to reboot the machine.Now TCP is ready to accept
up to 5600 TCP connections.
