Note: Large batches of XDEL requests issued to Duplex volumes
may result in significantly increased session delays. To avoid these
delays, consider issuing the XDEL commands while all volumes are suspended,
or issuing them in small batches across a period of several minutes.
- REQUEST=XDEL
- Deletes pairs of volumes from an XRC session.
- ,SID=sid
- A required input character field containing the XRC session
ID to which the request is sent. The ID is left-justified and padded
on the right with blanks.
To code: Specify
the RS-type address, or address in register (2)-(12), of a required
8-character field.
- ,PVOLSER=pvolser
- A required input field containing the primary volser of a volume
pair to be deleted, or ALL if all volume pairs are to be deleted.
To code: Specify the RS-type address, or address
in register (2)-(12), of a required 6-character field.
- ,RETINFO=retinfo
- A required output parameter field that is used to return detailed
information about the results of executing the
request. Information about the results of scheduling the
request are returned in the RETCODE and RSNCODE fields. Align the
area on a word boundary. The first 4-bytes contain the return code
and the second 4-bytes contain the reason code. The remainder of
the information is dependent on the return and reason codes. See the
coding example SDM API usability guide about how to coordinate the RETCODE,
RSNCODE, and RETINFO fields.
To code: Specify
the RS-type address, or address in register (2)-(12), of a required
100-character output field.
- ,MESSAGES=messages
- A required output parameter field in which ANTRQST will place
the address of a buffer containing messages about the results of executing
the request. These are the messages that would have been returned
to the caller if the TSO interface had been used. If there are no
messages, the address will be zero.
An ANTRQST message buffer has
the following format:
- Bytes 1-4 contain the size of the ANTRQST message buffer.
- Byte 5 contains the subpool of the ANTRQST message buffer.
- Byte 6 is not used.
- Bytes 7-8 contain the number of messages in the array that follows.
The rest of the message buffer is an array of messages.
Each message has the following format:
- Bytes 1-2 contain the size of the message in bytes 3-x.
- Bytes 3-x contain the message.
To code: Specify the RS-type address,
or address in register (2)-(12), of a required 4-character field.
- ,ECB=ecb
- ,ECB=NO_ECB
- An optional input parameter field that SDM posts for an asynchronous
request. This field is ignored for synchronous requests.
The default
is NO_ECB.
To code: Specify the RS-type
address, or address in register (2)-(12), of a fullword field.
- ,ATTIME=attime
- ,ATTIME=NO_ATTIME
- An optional input parameter field that contains the UTC timestamp
of when the volumes are to be deleted. The format is YYYY.DDD HH:MM:SS.THMIJU.
This field is required if the ETYPE parameter value ATTIME is specified.
It is ignored otherwise.
The default is NO_ATTIME.
To code: Specify the RS-type address, or address
in register (2)-(12), of an optional 24-character input field.
- ,ETYPE=etype
- ,ETYPE=IMMEDIATE
- An optional input parameter field that specifies when the command
will be processed. The value is left-justified and padded on the right
with blanks. If the field contains binary zeros, the program uses
the default. The following options are available for use:
- ATTIME — indicates the XDEL command will be executed when
the specified UTC time is reached.
- CANCEL — indicates an outstanding XDEL command will be deleted.
- DRAIN — indicates the XDEL command will be executed when
the consistency group represented by the most recent timestamp of
all volumes being deleted has been applied.
- IMMEDIATE — indicates the XDEL command will be executed
as soon as the current consistency group has been applied.
The default is IMMEDIATE.
To code: Specify
the RS-type address, or address in register (2)-(12), of an optional
16-character field.
- ,WAITTIME=waittime
- ,WAITTIME=0
- An optional halfword input parameter field containing how long
in seconds SDM will wait for a request to complete. A value of zero
says to not time the request. If the time expires before the request
is complete a value of 7039 (RQST_WAITTIME_EXPIRED [see ANTRQSTL])
will be returned. If the request is a synchronous request, the value
will be placed in the return code part of RETINFO. If the request
is an asynchronous request the value will be used as the ECB post
code.
The default is 0.
To code: Specify
the RS-type address, or address in register (2)-(12), of an optional
halfword input field.
