Four Most Common Problems
The four most common problems reported are as follows:
Setup or Upgrades: The most frequently asked Host Integration Server questions are related to setup or upgrade issues. Examples of VTAM configurations for connecting to a mainframe can be found in the Host Configuration section. The configuration file (COM.CFG) contains almost all of the configuration information for the Host Integration Server environment. It is extremely important to back up this file before making changes.
Connectivity Issues: If you are having a problem connecting to the host, determine where the problem originates. Because Host Integration Server is the middle piece of a three-part connection, it helps to narrow the problem down to a Host Integration client, Host Integration Server issue, or a Host Integration Server host issue.
