Deleting Objects from the SYSGEN Tape

Deleting autoboot images

The DAUTO command (abbreviated DA) deletes the specified autoboot type from the list of files dumped onto SYSGEN's tape. The command has the following parameter:

   DAUTO    [TYPE  =   DISC ] 

                     [ TAPE ] 

                     [ BOTH ]

TYPE specifies the type of autoboot file deleted. The following types are allowed:

Deleting an autoboot file, creating a SYSGEN tape, and updating your system using the newly generated tape does not remove the disk autoboot file from the system. Remove the disk file using the ISL INSTALL command.

Deleting boot images

The DBOOT command (abbreviated DB) deletes a boot image file name. If the boot image has an associated library, DBOOT also deletes the library. DBOOT has the following parameter:

   DBOOT (DB)     [IMAGE     =] bootimagename

IMAGE is a repeated parameter that specifies which boot image names you want to delete. If a specified boot image name does not exist in the configuration, a warning is issued.

Use the SHOW command to display a listing of the applicable boot image file names.

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.
