Is there a limits on how many NODE/ CONNECT statements that can be added to the CCIPARM member?
There is no limits for the amount of NODE/Connect statements that can be placed within the CCIPARM member.
The CCITCPGW limit is controlled by TCPIP and OMVS parms, not CCI or ENF parameters.
MAXSOCKETS, MAXTHREADS and MAXTHREADTASK are the fixed limits for TCPIP.
However, the amount of connections is also restrained by the available system
resources for the address space, such as storage. There is no formula to
calculate what these limits are because they vary from environment to
environment based on OS and LE levels. Most clients can safely connect
over 1000 systems (to CCITCPGW) before encountering a problem.
