called a saveabend file can be created by the DMON debug monitor when a process’s
SAVEABEND attribute is set and the process terminates abnormally.
small OSS file. A regular file that is smaller than approximately 2 gigabytes. Contrast with

used to contain files for a specific fileset. The storage pool includes the creation pool.
storage-pool file. A file containing a list of disk volumes to be used when creating new files
in a fileset. As these volumes are filled, more volumes can be added to the storage-

target directory location (TDL). The absolute pathname within the target OSS
environment where the OSS files for configuration are placed. One TDL can contain

A7CINFO file for each product and are transmitted to the target system in the
activation package instructions.
target subvolume (TSV). The subvolume name of a disk location on the target system
where the software files for configuration are placed. One TSV can contain files for a
single product or multiple products. TSV names are contained in the A0CINFO file for

instructions.
