UNIX Analysis Preparation

z/OS UNIX configuration begins with the BPXPRMxx Parmlib members used at IPL. The member names can be specified with:

The OMVS= keyword in the IEASYSnn master Parmlib member:
```
OMVS=nn
```
nn
Specifies member BPXPRMnn)
```
OMVS=(nn)
```
nn
Specifies member BPXPRMnn)
```
OMVS=(nn,mm)
```
nn

Specifies member BPXPRMnn

mm

Specifies member BPXPRMmm
The OMVS= parameter in response to the “ENTER SYSTEM PARAMETERS” prompt at IPL. When specified in this manner, the BPXPRMxx members specified override those specified in IEASYSxx members used at IPL.

If multiple members are specified the first instance of a BPXPRMxx parameter is used.
