This information describes the search orders used in the z/OS® UNIX environment
for the different file types shown in
Table 1. The z/OS UNIX socket
functions use various types of TCP/IP data sets and files. They include:
- Base resolver configuration files
- Translate tables
- Local host tables
- Protocol information
- Services information
- Host alias table
The particular file or table chosen can be either an MVS™ data set or z/OS UNIX file, depending on the resolver
configuration settings and the presence of given files on the system.
Note: A program's first resolver service request initializes the resolver
definitions that will be used for all resolver requests. For long
running programs, the definitions can be modified by use of the MODIFY
REFRESH operator command. For command usage and syntax, see
z/OS Communications Server: IP System Administrator's
Commands.
