Issue
.DAT files and what their purpose is.
Another good practice for the Removal of the "DAT" files is this: Anytime a Tech goes to a site, it is wise to remove all the "DAT" files Prior to attaching a Laptop to a new site. This way you will not corrupt this site routing tables with bogus IPs and Links.
Environment
I/NET site with profiles, DLA or non DLA architecture DAT, .dat, profile,
Cause
Profile corruption or Reference host issues can be resolved by renaming and then recreating the .DAT file.
Resolution
.DAT files contain the routing table that the Netcon gets the data from.
Profiles:
The I/NET Configuration program allows you to specify and save more than one set of configuration specifications. These specifications are called profiles. The majority of host workstations only require one profile. However, multiple profiles are useful if you work with several different TAC I/NET Seven environments, because you can change system parameters simply by selecting a different profile. Most of the configuration parameters are saved in the system registry and IP routing information specific to each profile is stored in a .DAT file. Note: There may be differences in the routing data for each configuration profile; consequently, you should not change configuration profiles in a stable TAC I/NET Seven network.
Reference Hosts
A host workstation, NPR, or Xenta 527/527-NPR must have knowledge of the other devices on the network in order to communicate with them. This knowledge is stored in what is commonly called a routing table. A routing table will contain the IP address of the devices known to the host workstation. When the host has data to route to another TAC I/NET Seven device, it uses the addressing information contained in the routing table to determine the destination path. I/O Server stores the routing table in a .DAT file.
