Plan the MIMINIT Member

The MIMINIT member for the parameter data set contains statements that specify initialization values for CA MIM. This member is pointed to in the PROCMIM member on the PROC MEMBER=MIMINIT statement. The initialization members specific to CA MIM do the following:

Define control and checkpoint files data sets. You can direct CA MIM to allocate dynamically these types of data sets. Use the following parameters:
- ALLOCATE DDNAME
- ALLOCATE DSNAME
- ALLOCATE XESFILEID
- ALLOCATE STRNAME
Define the CTC device addresses connecting systems. Use the following parameters:
- CTCPATH ADDRESS
- CTCPATH FROMSYSTEM
- CTCPATH TOSYSTEM
Identify the systems participating in the MIMplex. Use the following statement:
- DEFSYS
Define Virtual Control File (VCF) master system and recovery options. Use the following parameters:
- GLOBALVALUE ANYELIGIBLE
- GLOBALVALUE MOSTPREFERRED
- GLOBALVALUE NOMASTER
- GLOBALVALUE VCFMASTER
Define general initialization values that affect the entire address space. The MIMINIT statement is used to define the following:
- Communication method. Use the following parameter:
  - MIMINIT COMMUNICATION
- Facilities to activate. Use the following parameters:
  - MIMINIT ECMF
  - MIMINIT EDIF
  - MIMINIT GCMF
  - MIMINIT GDIF
  - MIMINIT GTAF
  - MIMINIT ICMF
  - MIMINIT TPCF
  Facilities are activated on the MIMINIT statement by specifying ON or OFF. For example,
```
MIMINIT ECMF=ON, GDIF=ON, EDIF=ON,   /* ALL MII FACILITIES
                 GTAF=ON, TPCF=ON,   /* ALL MIA FACILITIES
                 GCMF=ON, ICMF=ON    /* ALL MIC FACILITIES 
```
  Once a facility has been activated on the MIMINIT statement, facility-specific initialization statements are eligible for processing. Use the following parameters:
  - GDIINIT
  - EDIINIT
  - GTAINIT
  - GCMINIT
  - ICMINIT
  - TPCINIT
- Selectable features to activate. Use the following parameter:
  - MIMINIT FEATURE=name
    Multiple features can be specified on a single MIMINIT statement, or a separate MIMINIT statement can be used for each feature. For example:
    
    MIMINIT FEATURE=Hyperstar
- I/O buffer sizes. Use the following parameters:
  - MIMINIT BLKSIZE
  - MIMINIT VCFBUFFERSIZE
  - MIMINIT VCFMAXBLOCKS
- SAF command security options. Use the following parameters:
  - MIMINIT SAFCMDAUTH
  - MIMINIT SAFPREFIX
- Component-specific PDS members to use. Use the following parameter:
  - MIMINIT MEMBER
- Names of systems and subsystems. Use the following parameters:
  - MIMINIT SUBNAME
  - MIMINIT MIMPLEX
  - MIMINIT SYSID
- Message handling. Use the following parameters:
  - MIMINIT LOGPARAMETERS
  - MIMINIT MSGPREFIX
  - MIMINIT MSGTEXT
  - MIMINIT SIGNON
  - MIMINIT SUPPRESSRESP
- Execution attributes. Use the following parameters:
  - MIMINIT BATCHJOB
  - MIMINIT CANCEL
  - MIMINIT PAGEFIX
- Control files settings. Use the following parameters:
  - MIMINIT COMPATLEVEL
  - MIMINIT FORMAT
  - MIMINIT MODE
- Command settings. Use the following parameters:
  - MIMINIT CMDPREFIX
  - MIMINIT COMMANDS
