Optional Preprocessing Commands for SYSGENR
and system library. To accelerate user-created program files before running
SYSGENR, you run the Accelerator program specifying the LINKABLE option. For
information on how to run the Accelerator program, see the Accelerator Manual.
Optional Preprocessing Commands for SYSGENR
Using DSM/SCM, you can enter ASSIGN and PARAM commands to specify unique
run-time parameters that can override your default system parameters. These
commands can assign process file names, select backup media formats, set file
security attributes, define default disk areas for work files, or reuse SYSGENR work
files. For more information on uses of the ASSIGN and PARAM commands, refer to
Section 3, Using Preprocessing Commands.
Output From SYSGENR
Depending on the options you specify, SYSGENR can produce the following:
•
A log of SYSGENR activity (the CONFLIST file)
•
One or more system image disks (SIDs)
•
One or more system image tapes (SITs)
CONFLIST File
The CONFLIST file contains a listing of all the SYSGENR commands and system
responses, including error and warning messages, that occur during processing of the
configuration files and building of the new operating system. Section 5, Reading the
CONFLIST Report, describes in detail the contents of the CONFLIST file for the
SYSGENR program.
If an error occurs, SYSGENR stops after the CONFLIST file is complete. If the error is
severe, termination is immediate, leaving the CONFLIST file incomplete. Each
warning and error message is entered in the CONFLIST file at the point where the
problem was noticed. These warning and error messages are documented in
Appendix A, SYSGENR Messages. If SYSGENR completes the CONFLIST file without
error, the system image can be placed on disk or tape.
System Image Disk (SID)
DSM/SCM always runs DISKGEN to place the newly created operating system files
into its activation package. This package can then be placed on a disk (a SID).
