VMSERV VMSERV VMSEEV is an EXEC procedure that is included on the System Program Update Tape (PUT) to assist you in the application of IBM service
updates to the VM/370 system. VMSERV directs the installation of
maintenance and service updates to the components and program products
that form your system. It is recommended that VMSERV be allowed to
apply service sequentially. The individual service EXECs contained on
the PUT are designed to apply service in the prescribed order.
The format of the VMSERV EXEC command is:
r , I I VMSERV I I I L RESTART BUILD PROGID SIPOE NORESP NOIPL EXIT NOMEMO SIPOMEM COMP -------------------------------------------------------, I I Ir ,r,r,r, I IRESTART (PROGID] I ISIPOE I I NOIPLI INOMEMO I I IBUILD (PROGID] I INORESPI IEXIT I ISIPOMEMI I L J L J L J L J (COM P ] I f I I , I returns control to VMSERV after an IPL of a nucleus or any
other event that causes V"SERV not to regain control.
creates a new nucleus. This option assumes you have loaded
all service from the system PUT. specifies the program number of the product you are servicing.
suppresses prompting messages related to specific service
applications and staging area disk addresses.
suppresses prompting messages' for staging area disk addresses. You will receive prompts to offer service to each component
and any applicable program products.
loads the service from the system PUT but does not create and (IPL) a nucleus for any component that is serviced. Because '"SERV does not normally lose control with this option, all of
the service on the PUT is loaded at one time. You may then BUILD the desired nucleus after applying corrective PTF's or
any user modifications.
installs service sequentially up to the point where a nucleus
would be created and loaded via IPL. 'MSERV exits at this
point.
suppresses printing of the Memo-to-Users. prints the SIPO/E user memos.
specifies the component that is intended to receive service.
If BUILD is also specified, COMP is the nucleus of the
component that you are building. The default is CPa You can
also specify CMS, IPCS, or RSCS. 394 IBM VM/370 Planning and System Generation Guide

VMSERV 1. PROGID is a positional parameter which is valid only if you specify RESTART or BUILD. 2. The parameters that are separated vertically are mutually
exclusive. They cannot be specified at the same time. For
example, specifying BUILD and NOIPL is not allowed.
3. If you are using SIPO (System Installation Productivity Option), refer to the VM System IPO Extended Planning Guide, Order No.
GC20-1874. HOW VMSERV WORKS The PUT is composed of two or more virtual tapes stacked sequentially.
Each virtual tape contains the service for product. The first
virtual tape on the PUT contains the service for the VM/370 System Control Program (SCP). The VMSERV EXEC is included in file one along
with the SCP service installation EXEC (5749010) and the program level
file. Assuming you need a new map of the PUT, certain housekeeping
functions are performed. VMSERV erases work EXECS PTFLVL and PTFMEMO, and issues a CP REWIND and VMFPLC2 FSF in an attempt to insure this is
the correct tape. VMSERV then initializes the EXECs necessary to print
the Memo-to-Users and user memos. The tape is rewound and VMFPLC2 looks
for space on an A-disk on which a TAPE MAP can be written. A TAPE MAP is created for files one and two. Any selective-load EXECs that may
have remained from the last PUT are erased and the new service EXECs are
created. A line of data is printed to the console to indicate where you
are in the procedure and the remaining virtual tapes are skipped. VMSERV offers to print the PUT DOCUMENT and the Memo-to-Users, reminding
you to review the memos prior to installing service. You are also
reminded of the NOIPL option of VMSERV, and since you probably have not
reviewed the memos at this point, VKSERV exits. Specify RESTART to
apply service to this product. VMSERV invokes the service (progid) EXEC with the applicable parameters that you entered when you invoked VMSERV. After the service for all the desired products is installed, VKSERV types the SERVICE DISKMAP to the console to show the service status of
all the products on the tape. I INITIALIZATION MESSAGES Several messages may be issued to you during the application of service.
The messages both normal and error that VMSERV issues are documented
here. VKSERV MUST BE RUNNING FROM YOUR 'C' DISK. PLEASE REVIEW THE INSTALLATION INSTRUCTIONS CONTAINED IN THE PLC'S COVER LETTER.
Return code: 4
Issued if the VKSERV EXEC is not running from the 'C' disk. Part 5. Updating VM/370 395
