Access to HOM Interface
Sometimes after an IPL an operating system does not know its sender paths to the coupling facilities in the sysplex. In this case the automation functions call the HCD HOM interface to determine the missing path information.
As the HOM interface must not run authorized the interface is called via a started task. The input and output data sets used by the started tasks are dynamically allocated and deleted by the NetView address space. This requires the RACF® ALTER access to these data sets for NetView.
When the address space of the started task is created, the operating system assigns a
user ID to the started task. User IDs are assigned either by using STARTED profiles or by using the
ICHRIN03 table (see z/OS Security Server RACF System Programmer's Guide). The user ID
must have RACF UPDATE authority to the data sets. The data set names are created as
follows:
hlq.domain.HSAyyddd.Xhhmmss- hlq
- is the high-level qualifier for temporary data set defined during the configuration
- domain
- is the domain ID of the current NetView
- X
- O or P
