MPE/iX 5.5 Operating System Limits

a) TCP Connections : Require additional 600+ connections.
Number of TCP connections currently available : 6000+
b) Sockets : Require additional ~600 sockets.
c) Ports :
Each VTSERVER process on a system has the following ports :
1) Request port (CM Port, VTTM only)
2) VTSERVER main port( IOWAIT Port). (CM Port, VTTM & VTAM)
3) LDM port (Procedure server : vt_ldm, messages to LDM, VTAM only).
4) LDM reply port ( Messages from LDM to AM,VTAM only).
5) Standard Signal Port (1) (VTTM & VTAM)
6) Standard Message Port (2) (VTTM & VTAM)
7) Standard Interrupt Port (3) (VTTM & VTAM)
Total number of ports requred : 15,600 (assuming all servers are VTSERVERS)
Number of ports available on system : 32,765
d) Port dictionary (for CM ports)
If all processes are VTTM then ~5500 entries are required in port dictionary.
If all processes are VTAM then ~2700 entries are required in port dictionary.
Additional Port dict entries = 5500 - 4000(current max) = 1500 (assuming all servers are
VTTM)
Number of Port dictionary entries reqd. : 5500
Number of Port dictionary entries available : To be increased to 8192.
