The default OMVS segments reside in a USER profile and a GROUP prof installation selects the names of these profiles, using a profile in class. The name of the FACILITY class profile is BPX.DEFAULT.USER. The application data field contains the user ID and the group name. The the user ID specified contains the UID, and the group profile f specified contains the GID.

In order to use this default USER/GROUP support, the following need

Ÿ Make the FACILITY class active.

ŸDefine BPX.DEFAULT.USER with APPLDATA(' uuuu/gggg') whereuuuu

specifies a	default user ID of 1gggg-8 charactersspecifie anddefault group
name of 1-8	characters.	The	USERuuuu profileneeds		to	have	an	OMVS
segment with	the default UID, HOME,			and	PROGRAM.		The	GROUP profile
gggg needs	to have an	OMVS	segment	giving	the	default		GID.

Ÿ If only default user information is needed,uuuuuse'). APPLDATA ('

The processing of the default OMVS segments for the user and the c connection group are independent of each other. The OMVS segment of specified on the initUSP may be used to obtain the UID, and the from the group ID specified in the FACILITY class profile. Similarly, default UID found through the user ID specified in the FACILITY used, the GID may come from the user's current connect group. Also specified in the FACILITY class profile does not need to be a mem specified in that profile. These values are used independently.

Run-Time Library Services

The Run-Time Library Services (RTLS) of OS/390 introduce new contents supervisor support to facilitate the binding of applications to a spe run-time environment defined on an installation basis. System programmers use FACILITY class profiles and RACF's program control when there is a control access to run-time libraries and the programs that use the r
