The parameter descriptions are listed in alphabetical order. Default
values are underlined:
- ,ACTUALVECLEN=actualveclen
- Use this output parameter to specify a fullword field to receive
the count of the new number of entries for the list notification vector
or local cache vector after your MODIFYVECTORSIZE request has been
processed. This field is valid only when a return code of X'4' is
returned.
To Code: Specify the RS-type name or address
(using a register from 2 to 12) of the fullword field to contain the
new vector length if it differs from the requested vector length.
- ,ALLEMPVAL=allempval
- Use this input parameter to specify the label to branch to if
all monitored objects (comprised of lists and/or the user's event
queue) in the range of vector entries are EMPTY (list notification
vector), or if all vector entries are VALID (local cache vector).
To Code: Specify the RS-type name or address (using a register
from 2 to 12) of the label.
- ,BITSTRING=bitstring
- BITSTRING is a required output field that contains vector entry
state information for the range of vector entries specified. This
field contains 32 bits. The first bit represents the first vector
index entry specified on the VECTORINDEX parameter and continues up
to a maximum of 32 vector index entries. The bits are interpreted
as follows:
- 0 - the vector entry corresponding to this bit position indicates
that the monitored list or event queue is NON-EMPTY (list notification
vector) or that the local cache entry is INVALID (local cache vector).
- 1 - the vector entry corresponding to this bit position indicates
that the monitored list or event queue is EMPTY (list notification
vector) or that the local cache entry is VALID (local cache vector).
To Code: Specify the RS-type name or address (using
a register from 2 to 12) of a fullword field.
- ,BRANCHTABLE=NO
- ,BRANCHTABLE=YES
- Use BRANCHTABLE=NO to specify that IXLVECTR should not generate
a branch table.
With the MODIFYVECTORSIZE request, use BRANCHTABLE=YES

labels you specify for MODIFYDONE, LESSTHAN, NOSTORAGE, INVALIDTOKN,
and INVALIDLEN.
With the LTVECENTRIES request, use BRANCHTABLE=YES
to specify that IXLVECTR should generate a branch table using the

- Use this input parameter to specify the label to branch to if
the value you specify using the VECTORLEN parameter is not valid.
To Code: Specify the RS-type name or address (using a register
from 2 to 12) of the label.
- ,INVALIDTOKN=invalidtokn
- Use this input parameter to specify the label to branch to if
the vector token you specified was not valid.

the RS-type name or address (using a register from 2 to 12) of the
label.
- ,LESSTHAN=lessthan
- Use this input parameter to specify the label to branch to if
the IXLVECTR service cannot obtain sufficient storage to enlarge your
list notification vector or local cache vector to the size you requested.
To Code: Specify the RS-type name or address (using a register
from 2 to 12) of the label.
- ,LSTEMPTY=lstempty
- Use this input parameter to specify the label to branch to if
the IXLVECTR service finds the list or event queue of interest empty.
To Code: Specify the RS-type name or address (using a register
from 2 to 12) of the label.
- ,LSTNONEMPTY=lstnonempty
- Use this input parameter to specify the label to branch to if
the IXLVECTR service finds the list or event queue of interest non-empty.
To Code: Specify the RS-type name or address (using a register
from 2 to 12) of the label.
- ,MODIFYDONE=modifydone
- Use this input parameter to specify the label to branch to if
the IXLVECTR service is able to modify the list notification vector
or local cache vector as requested.
To Code: Specify the
RS-type name or address (using a register from 2 to 12) of the label.
- ,NOSTORAGE=nostorage
- Use this input parameter to specify the label to branch to if
the IXLVECTR service cannot obtain any storage to enlarge your list
notification vector or local cache vector to the size you requested.
The vector's size remains the same.
To Code: Specify the
RS-type name or address (using a register from 2 to 12) of the label.
- ,REQUEST=MODIFYVECTORSIZE
- ,REQUEST=LTVECENTRIES
- ,REQUEST=TESTLISTSTATE
- ,REQUEST=TESTLOCALCACHE
- Use REQUEST=MODIFYVECTORSIZE to modify the size of your list notification
vector or local cache vector.
Use REQUEST=LTVECENTRIES to load
and test a range of vector entries associated with a local vector
for either a list or cache structure.
Use REQUEST=TESTLISTSTATE
to test whether a list or an event queue you are monitoring is empty
or non-empty.
Use REQUEST=TESTLOCALCACHE to test whether a
data item in your local cache buffer is valid.
- ,RETCODE=retcode
- Use this output parameter to specify a fullword field to contain
the return code, which is also returned in register 15.
To
Code: Specify the RS-type name or address (using a register from
2 to 12) of the fullword field.
- ,SOMENEINV=someneinv
- Use this input parameter to specify the label to branch to if
some monitored objects (comprised of lists and/or the user's event
queue) in the range of vector entries are NON-EMPTY (list notification
vector), or if some entries in the range of vector entries are INVALID
(local cache vector).
To Code: Specify the RS-type name
or address (using a register from 2 to 12) of the label.
- ,VALIDATE=YES
- ,VALIDATE=NO
- Use VALIDATE=YES with TESTLOCALCACHE as follows:
- When you omit VECTORINDEX, to request that the system validate
connectivity to the coupling facility
- When you specify VECTORINDEX, to request that the system validate
connectivity to the coupling facility and check the validity of a
particular data item
Use VALIDATE=NO with TESTLOCALCACHE and VECTORINDEX to request
that the system check the validity of a particular data item without
validating connectivity to the coupling facility. You would choose
this option only if a previous serialized request was done with VALIDATE=YES
and the serialization has not yet been released.
- ,VECTORINDEX=vectorindex
- With the LTVECENTRIES request, use this input parameter to specify
the starting index of the range of vector entries that are to be loaded
and tested. The index specified must be evenly divisible by 32. Thirty
two consecutive vector entries will be loaded and tested. The vector
index for a given vector size of N goes from zero to N-1.
With
the TESTLISTSTATE request, use this input parameter to specify a fullword
field that contains the vector index entry associated with the list
or event queue of interest. For a vector with N entries, valid vector
index values range from zero to N-1. The association between the particular
index number and the list or event queue must already be established
using the IXLLIST macro.
With the TESTLOCALCACHE request,
use this input parameter to specify a fullword field that contains
the vector index entry to be tested for validity. For a vector with
N entries, valid vector index values range from zero to N-1. The association
between the particular index number and the data item must already
be established using the IXLCACHE macro.
For more information
about the IXLLIST or IXLCACHE macros, see z/OS MVS Programming: Sysplex Services Guide.
To
Code: Specify the RS-type name or address (using a register from
2 to 12) of the fullword field.
- ,VECTORLEN=vectorlen
- Use this input parameter to specify a fullword field containing
the new total number of entries in the list notification vector or
local cache vector. The new number of entries can be greater than
or less than the current number of entries but must be greater than
zero and be a multiple of 32. If you specify a number that is not
a multiple of 32, the system will round up the number to a multiple
of 32.
The system will attempt to expand or contract your vector
to the size you specify.
To Code: Specify the RS-type
name or address (using a register from 2 to 12) of the fullword field
that contains the requested vector length.
- VECTORTOKEN=vectortoken
- Use this input parameter to identify the list notification vector
or local cache vector on which the specified request is to be performed.
The local vector was initially created by the IXLCONN service,
if requested, and the vector token was returned in the connect answer
area (IXLYCONA) in the field CONAVECTORTOKEN.
To Code: Specify
the RS-type name or address (using a register from 2 to 12) of a 12-character
field that contains the vector token.
- ,WORKAREA=workarea
- Use this input parameter to specify a 20-byte save area to be
used by the IXLVECTR service.
To Code: Specify the RS-type
name or address (using a register from 2 to 12) of a 20-character
field that begins on a word boundary.
