Updates to the communications database for VTAM (SNA) connections to a data sharing group

Changes to the SYSIBM.LOCATIONS, SYSIBM.LUNAMES, and SYSIBM.LULIST table take effect in the following manner for SNA connections:

• If the DDF has not yet tried to communicate with a particular remote group, updates take effect when DDF attempts to communicate with that group.
• If the DDF has already attempted to communicate with a particular remote group, updates take effect take the next time DDF is started.
• Updates do not affect existing conversations; existing conversations continue to operate as if the updates had not occurred.
