Updates to the communications database for TCP/IP connections

You can update the CDB while DDF is active.

Changes to the SYSIBM.LOCATIONS, SYSIBM.IPNAMES, SYSIBM.IPLIST tables take effect in the following manner for TCP/IP connections:

• Updates take effect when DDF opens a new connection to the remote group.
• Updates do not affect communication already in progress; existing communication continues as if the updates had not occurred.
