SYSRES PIacro The following SYSRES macro defines the system residence volume as the
2314 volume with a serial number of CPDSK1. During the system
generation procedure this volume is found at address 230. The VM/370 system starts at cylinder 198, the error r:cording area starts at
cylinder 4, and the warm start storage area 1S cylinder 202 and the
checkpoint start storage area is cylinders 101 and 102. The format of the SYSRES macro is: SYSRES SYSVOL=CPDSK1,SYSRES=230,SYSTYPE=2314,SYSNUC=198, SYSERD=4,SYSWDM=(202,1),SYSCKP=(101,2) The formula for each device type is shown in Figure 21.

SYSOPR Macro SYSOPR Macro Use the SYSOPR macro instruction to specify the system operator's
userid, and the userid of the operator who is to receive VM/370 system
dumps. The same userid may be specified in both operands.

must not be specified for the SYSOPR macro
The format of the SYSOPR macro is:
r----------------·----------------------------------------------------------, , Name Operation Operands I I 1 , , I I , I I L- SYSOPR r , ISYSOPER=userid I L J r , I,SYSDUMP=userid I L J r , ISYSOPER=OPERATORI ISYSOPER=userid I L J is the userid of the virtual machine to be assigned to the system
operator. If SYSOPER is not specified, the userid OPERATOR is
used.
The userid is a character string up to 8 characters long.
r , ISYSDUMP=OPERATNSI ISYSDUMP=userid I L J is the userid of the virtual machine whose spool input receives the
system dump file after a system restart. This userid also receives
quest virtual machine dumps produced by the CP command VMDUMP, if
you specify the destination as SYSTEM in the VMDUMP command. If SYSDUMP is not specified, the userid OPERATNS is used. If you
intend to use IPCS, allow this operand to default to OPERATNS or
specify the IPCS userid.
The userid is a character string up to 8 characters long.
The following SYSOPR macro designates the OP virtual machine as the
system operator and directs the system dumps to the CPSYS virtual
machine. SYSOPR SYSOPER=OP,SYSDUMP=CPSYS 172 IBM VM/370 Planning and System Generation Guide
