1  SHARE
   On VAX systems, connects a processor to a multiport memory unit
   already initialized by this or another processor. The number and
   name of the specified multiport memory unit must be those of an
   initialized unit, or an error condition results.

   Use of the SHARE command requires the CMKRNL privilege.

   Format

     SHARE  MPMn MPM-name
 

2  Parameters
 

MPMn

   Specifies the number on the front panel of the multiport memory
   unit being connected.
 

MPM-name

   Specifies the name of the multiport memory unit as indicated in a
   previous SHARE/INITIALIZE command.
 

2  Qualifiers
 

/MAXCEFCLUSTERS

      /MAXCEFCLUSTERS=max-cef

   Specifies the maximum number of common event flag clusters
   that the processor can create in the multiport memory unit. The
   default is no limit.
 

/MAXGBLSECTIONS

      /MAXGBLSECTIONS=max-gbl

   Specifies the maximum number of global sections that the
   processor can create in the multiport memory unit. The default
   is no limit.
 

/MAXMAILBOXES

      /MAXMAILBOXES=max-mail

   Specifies the maximum number of mailboxes the processor can
   create in the multiport memory unit. The default is no limit.
 

2  Example

 SYSGEN>  SHARE MPM1 SHR_MEM_1

     This command connects a multiport memory unit. Because no
     qualifiers are specified, defaults apply to all the parameters.

     The unit with a 1 on the front panel must be initialized with
     the name SHR_MEM_1 for the command to work.
 

2  /INITIALIZE
   On VAX systems, initializes a multiport memory unit and connects
   it to the processor on which SYSGEN is running.

   Use of the SHARE/INITIALIZE command requires the CMKRNL
   privilege.

   Format

     SHARE/INITIALIZE  MPMn MPM-name
 

3  Parameters
 

MPMn

   Specifies the number on the front panel of the multiport memory
   unit being connected.
 

MPM-name

   Specifies the name by which the multiport memory unit is
   to be known to systems using it. The MPM-name is a 1 to 15
   alphanumeric character string that may contain dollar signs ($)
   and underscores (_).
 

3  Qualifiers
 

/CEFCLUSTERS

      /CEFCLUSTERS=cef

   Specifies the total number of common event flag clusters
   permitted in the multiport memory unit. The cef value is an
   integer with a default of 32.
 

/GBLSECTIONS

      /GBLSECTIONS=gbl

   Specifies the total number of global sections permitted in the
   multiport memory unit. The gbl value is an integer with a default
   of 32.
 

/MAILBOXES

      /MAILBOXES=mail

   Specifies the total number of mailboxes permitted in the
   multiport memory unit. The mail value is an integer with a
   default of 32.
 

/MAXCEFCLUSTERS

      /MAXCEFCLUSTERS=max-cef

   Specifies the maximum number of common event flag clusters
   that the processor can create in the multiport memory unit. The
   default is no limit.
 

/MAXGBLSECTIONS

      /MAXGBLSECTIONS=max-gbl

   Specifies the maximum number of global sections that the
   processor can create in the multiport memory unit. The default
   is no limit.
 

/MAXMAILBOXES

      /MAXMAILBOXES=max-mail

   Specifies the maximum number of mailboxes the processor can
   create in the multiport memory unit. The default is no limit.
 

/POOLBCOUNT

      /POOLBCOUNT=block-cnt

   Specifies the number of blocks allocated to the multiport memory
   unit's dynamic pool. The block-cnt value is an integer with a
   default of 128.
 

/POOLBSIZE

      /POOLBSIZE=block-size

   Specifies the size of each block in the dynamic pool. The block-
   size value is an integer with a default of 128 bytes.
 

/PRQCOUNT

      /PRQCOUNT=prq-cnt

   Specifies the number of interprocessor request blocks (PRQs)
   allocated. The prq-cnt value is an integer with a default of 64.
 

3  Description
   If the specified multiport memory unit is already initialized and
   connected to other active processors, the gbl, mail, cef, block-
   cnt, block-size, and prq-cnt parameter values are ignored, and
   the unit is simply connected to the processor.
 

3  Example

 SYSGEN>  SHARE MPM1 SHR_MEM_1/INITIALIZE -
 SYSGEN>  /GBLSECTIONS=128/MAILBOXES=64/CEFCLUSTERS=0

     This command initializes a multiport memory unit with defaults
     on all but the gbl, mail, and cef parameters. In this example,
     assume that the number of the multiport memory unit as it
     appears on the front panel is 1, and the unit name is SHR_
     MEM_1.
