STRMNPS start option

If subplexing is in effect for this VTAM® node (that is, start option XCFGRPID=vv was specified), the actual structure name that VTAM will attempt to connect to will be suffixed by the XCF group ID. Thus, if XCFGRPID=11 was specified, the default structure name would be ISTMNPS11 and if STRMNPS=ISTMYSTR was coded, VTAM would connect to the structure ISTMYSTR11. The fully suffixed MNPS structure name that will be accessed by this VTAM can be displayed by issuing the D NET,ID=VTAM command.

STRMNPS=ISTMNPS

Specifies the default name of the MVS™ coupling facility structure to be used for multinode persistent sessions.

STRMNPS=NONE

Specifies that VTAM will not check for the existence of a multinode persistent sessions coupling facility structure. Coding STRMNPS=NONE disables the multinode persistent sessions function for this VTAM, even if a structure has been defined.

STRMNPS=structure_name

Specifies a multinode persistent sessions structure name that is 1-16 characters in length. If subplexing is in effect, the structure_name value can have only up to 14 characters. The name can contain numeric characters, alphabetic characters, national characters ($, A, #) or an underscore (_). The first 3 characters of the name must begin with IST.

Note: If you are using multiple coupling facility structures for multinode persistent session support, the number of characters used to specify the name of the base structure (STRMNPS start option) including the 2-digit group ID suffix (if subplexing is in effect), must account for characters needed for unique names for all alternate structures. See z/OS Communications Server: SNA Network Implementation Guide for information about using alternate structures.
