Updating C!!S If you entered ALL, the installation procedure applies all the text
files that affect the CMS VSAM and access method services support. If
you entered SELECT, the installation procedure sends you a message each
time it finds a text file that is used by CMS to support VSAM and access
method services. You must reply to these messages: DMSVPD383R APPLY 'filename'? ••• ENTER 'NO' OR EOB: Before VSAMGEN writes a new text to the A-disk, it checks that a
module with that name already exists on the A-disk, erases any old text
file with that name, renames the current text file to fn TEXTOLD, and
writes the new text file on the CMS A-disk. When the new text file
replaces the old, you receive the message: DMSVPD367I 'fn TEXT' WRITTEN ON DISK 'A'. When all the new text files are written to the CMS A-disk# you receive the status message: DMSVPD3681 nn NEW PTF DECKS WILL BE A·PPLIED From this point on, the procedure for updating VSAM and access method
services is identical to the installation procedure for fetching,
link-editing, loading, and saving them. You receive the following
messages: DMSVGN3621 LINK-EDITING {CMSVSAM} ••• CMSAPIS DMSVGN3631 {CPISVSAft} DOSLIB CREATED ON DISK 'A' CMSAMS DMSVGN363R ENTER LOCATION WHERE {CMSVSAM} WILL BE LOADED AND SAVED: CMSAMS DMSVGN366R ENTER NAME OF SYSTEM TO BE SAVED: VSAMGEN fetches the modules, loads
assigns storage protection keys, and
the completion message:
them at the designated address,
saves the segments. You receive DMSVGN3651 SYSTEM segmentname SAVED. Finally, you must indicate whether or not you wish to erase the DOStIB created during link-edit. You receive the following message: DMSVGN368R ERASE {CPISVSAM} DOSLIB? ••• ENTER YES OR NO: CMSAPIS Updating Considerations for CMS/DOS CPIS/DOS has no on the update procedures for DOS/VS, DOS/VS COBOL, or DOS PL/I. You should follow the normal update procedure for applying
IBM-supplied coding changes to them. Part 5. Updating VM/370 361
