Modifying System File Configurations
Entering the SYSFILE Configurator
To delete one or more boot image file names, enter DBOOT and the file name(s) to be
removed at the SYSFILE prompt:
sysfile>DBOOT filename
Deleting Compatibility Mode Segments from a SYSGEN Tape
The DCMSL command (abbreviated DC) deletes segments from the compatibility mode
segmented library (CMSL). The DCMSL command has the following parameter:
DCMSL (DC) [SEG =] segment-name,...
SEG is a repeated parameter that specifies the existing segment name. If a nonexistent
segment name is specified, an error occurs.
Use the LCMSL command to list the contents of the CMSL.
Removing System Programs from a SYSGEN Tape
The DSPROG command (abbreviated DS) removes system programs or files from the system
configuration. DSPROG has the following parameter:
DSPROG (DS) [PROG =] programname,...
PROG is a repeated parameter that specifies the system program name to be deleted. If a
specified program name does not exist, an error occurs.
To remove a program or file name, enter the command and name:
sysfile>DS FCOPY.PUB.SYS
Deleting a system program does not remove it from the disk. To remove it from disk, an
ISL INSTALL must be performed.
Replacing Objects on the SYSGEN Tape
The replace commands (RAUTO, RBOOT, RCAT, RCMSL, RDCC, RIPL, RNMLIB, and RSPROG)
replace or modify information in the list of SYSGEN dump files.
RAUTO replaces an existing autoboot image or modifies the autoboot type.
RBOOT replaces an existing boot image or modifies the boot type.
RCAT replaces the message catalog.
RCMSL replaces a segment in the temporary copy of the CMSL.
