PSYS

Syntax explanations

• <name> is the name that you specify for the processor group. Enter this value as a character string from 1 to 8 characters long.
• nnnn is the last four digits of the CPU serial number. You must specify all four digits.
• <cputype> is a value no longer than 10 characters describing the type of CPU on the system, for example 9672-R66.
• <num> is an optional value specifying the processor speed (in millions of instructions per second). If you do not specify this value, UIE looks in the hardware table under the specified CPU type and uses the value found there. (The CPU type in the hardware table must be an exact match to what you specify in the PSYS command.)
• <sysid-list> is a list of system IDs for the logical systems running on this physical system. Each system id that you specify in this list must be separated from the others by a comma. There can be no blank spaces in the list.
• HWMSU is an optional parameter used to override the MSU value from the hardware table.
• MIPSPCP is the number of MIPS per CP (central processor).
• MIPSPSP is the number of MIPS per special processor.

• NPROC is the number of processors in a physical box not including ICF, IFL, and disabled engines. This parameter is optional.

  You must use either the SER or the SID parameter. If you specify the SER parameter, you do not have to specify the SID parameter. Conversely, if you specify SID, you can omit SER.

• NZAAP is the number of zAAP processors in a physical box. Specify the number of zAAP processors if the information provided by the type 70 records is missing or incorrect.
• NZIIP is the number of zIIP processors in a physical box. Specify the number of zIIP processors if the information provided by the type 70 records is missing or incorrect.
• NORMFACTOR is the normalization factor between the general purpose processor speed and the specialized processor speed. Specify this value if the information in the type 72 record is incorrect. This should be a number equal to or greater than 1.

Rules

If you do not override the parameters, these values are:

• PSYSnnnn for the system name, where nnnn is the last four digits of the processor's serial number.
• The CPU type that UIE finds in the RMF records.
• The MIPS rating for that CPU type in the hardware file supplied with the product.
• The HWMSU value comes from the MSU rating for that CPU type in the hardware file supplied with the product.
• NPROC and MIPS are usually optional. They are required in only two cases:
  • When the specified CPUTYPE is not found in the hardware table.
  • When you want to use MIPS and NPROC values that differ from those which are in the hardware table.
• The number of zAAPs and zIIPs as determined by UIE based on information in the type 70 records.
• The NORMFACTOR value for that CPU type based on information in the type 72 records.

You can specify a separate PSYS command for each system or you can specify one PSYS command for several z/OS images.

If you want to specify a MIPS value for CPs and a different MIPS value for special processors, specify MIPSPCP and MIPSPSP.

Specify MIPSPCP and MIPSPSP together. These parameters are mutually exclusive of the MIPS parameter, that is, either MIPS or both MIPSPCP and MIPSPSP can be present.
