Step 3. Determine where to specify the system name
The name of a system is also the substitution text for the &SYSNAME system symbol. You can
specify the name of a system in one or more of the following places:
- The IEASYMxx parmlib member
- The IEASYSxx parmlib member
- By the operator, in response to write to operator with reply (WTOR) message IEA101A SPECIFY SYSTEM PARAMETERS.
If you define the system name in only one of the listed places,
the system will use that definition. Otherwise, the system will determine
the name as follows:
- If the system name is specified in both IEASYMxx and IEASYSxx, the system will use the name in IEASYMxx.
- If the operator specifies the system name in response to the specify system parameters message, the system will use the name specified on the operator response.
IBM® suggests that you specify the system name in IEASYMxx.
Table 1 shows every possible way to specify the system name and the resulting system action. In the table, IEASYMXX indicates that the system name is specified in the IEASYMxx parmlib member, IEASYSXX indicates that it is specified in the IEASYSxx parmlib member, and WTOR indicates that it is specified in response to the specify system parameters prompt:
| IEASYMxx | IEASYSxx | Console SYSNAME (WTOR) | Resultant system name |
|---|---|---|---|
| IEASYMXX | IEASYMXX | ||
| IEASYMXX | IEASYSXX | IEASYMXX | |
| IEASYMXX | WTOR | WTOR | |
| IEASYMXX | IEASYSXX | WTOR | WTOR |
| IEASYSXX | IEASYSXX | ||
| IEASYSXX | WTOR | WTOR | |
| WTOR | WTOR |
If the system name is not defined in any of the listed places,
the system name will become, by default, one of the following:
- The processor name that is defined to HCD (if not in LPAR mode)
- The LPAR name that is defined to the processor (if in LPAR mode)
- A VM userid, if the system is running as a guest of VM/ESA.
