Defining the BPXPRMxx members in IEASYSxx

After you complete the installation, you need to specify OMVS=xx in the IEASYSxx member of SYS1.PARMLIB if you want to start in full function mode. If you do not specify the OMVS parameter or if you specify OMVS=DEFAULT, the kernel is started in minimum mode with all parmlib statements taking their default values. You can specify:

OMVS=nn, where nn is the BPXPRMnn member
OMVS=(nn,mm,...), where (nn,mm,...) is the set of BPXPRMxx members to use when locating parmlib statements to configure the system services. The first value set for a parameter is the one that is used; if a later member in the list specifies a different value, that value is ignored.
For example, say you have three systems that share parmlib members but do not want to share file systems. Define these parmlib members:
- BPXPRMLI, which specifies system limits for systems 1 and 2
- BPXPRML3, which specifies system limits for system 3, which needs more processes than the other two systems
- BPXPRMF1, which specifies file system setup for system 1
- BPXPRMF2, which specifies file system setup for system 2
- BPXPRMF3, which specifies file system setup for system 3
For system 1, the OMVS parameter on the IEASYSxx parmlib member is:
```
OMVS=(F1,LI)
```
For system 2, the OMVS parameter on the IEASYSxx parmlib member is:
```
OMVS=(F2,LI)
```
For system 3, the OMVS parameter on the IEASYSxx parmlib member is:
```
OMVS=(F3,L3)
```
If you want the BPXPRMxx member to be shared by more than one system, you must define system symbols in the IEASYMxx member. Symbols such as system name (&SYSNAME) can be used in BPXPRMxx when referring to file system names.

Example: In order to have different file systems mounted at /etc on each system in the sysplex:
```
MOUNT FILESYSTEM('OMVS.&SYSNAME..ETC')
     TYPE(HFS) MODE(RDWR) MOUNTPOINT (/etc)
```
