High-level qualifier

High-level qualifiers (HLQ) permit you to associate an application's configuration data set with a particular job name or TSO user ID, or permit you to use a default configuration data set for the application. The possible high-level qualifiers are:

• userid

  Userid is the TSO user ID which invoked the application.

• jobname

  Jobname is the application's batch JCL job name or the name of the application's started procedure.

• hlq

  TCP/IP is distributed with a default high-level qualifier of TCPIP. To override the default HLQ used by dynamic data set allocation, specify the DATASETPREFIX statement in the TCPIP.DATA configuration file. For most configuration files, the DATASETPREFIX value is used as the high-level qualifier of the data set name in the last step in the search order. Note that the DATASETPREFIX value is not used as the high-level qualifier of the data set name used as the last step in the search order for the TCPIP.DATA configuration file.
