Middle-level qualifiers
- Node name
Node name is an MLQ used in the search order for finding the configuration file PROFILE.TCPIP. Node name is determined by the parameters specified during VMCF initialization. For further information on initializing VMCF, see z/OS V2R2 Program Directory.
- Function name
The TCP/IP implementation of multicultural support and double-byte character set (DBCS) support requires the use of multiple translation tables. To facilitate the concurrent use of multiple languages and code pages, TCP/IP uses a middle-level qualifier to designate which server or client uses a particular translation table. STANDARD, the default MLQ, is available for use if a single translation table can be used by multiple servers or clients. The TCP/IP Telnet client and FTP provide a TRANSLATE parameter that permits you to specify your chosen MLQ to replace the function name for that invocation of the command. For example, SRVRFTP is used as an MLQ by the File Transfer Protocol server.
The following data sets are some of the data sets that are only dynamically allocated by TCP/IP in a configuration file search order (you cannot specify them with DD statements in JCL):
ETC.PROTO ETC.RPC
HOSTS.ADDRINFO HOSTS.SITEINFO
SRVRFTP.TCPCHBIN SRVRFTP.TCPHGBIN
SRVRFTP.TCPKJBIN SRVRFTP.TCPSCBIN
SRVRFTP.TCPXLBIN STANDARD.TCPCHBIN
STANDARD.TCPHGBIN STANDARD.TCPKJBIN
STANDARD.TCPSCBIN STANDARD.TCPXLBIN
- User ID or job name
- DATASETPREFIX value
