The Check Spooled File command checks for the existence of a spooled
file and optionally for whether the spooled file is still open. If
the job exists, but not the spooled file, TAA9883 is sent as an
escape message. If the job does not exist, TAA9884 is sent as an
escape message. If the option to check for an open status is used
and the file is still open, TAA9885 is sent as an escape message. If
the spooled file was deleted from the job, CPF3309 is sent as an
escape message.
The command is useful when a program needs to check for the existence
or status of a spooled file before performing an operation on it.
For example, if you submit a batch job, you may be interested in
knowing when a spooled file has been fully output (the file has been
closed) by the batch job.
A typical command to check existence of a spooled file would be:
CHKSPLF SPLF(xxx)
MONMSG MSGID(TAA9883) EXEC(DO) /* No such SPLF */
/* Your processing */
ENDDO /* No such SPLF */
To check if a spooled file is open, you would specify:
CHKSPLF SPLF(xxx) CHKOPEN(*YES)
MONMSG MSGID(TAA9885) EXEC(DO) /* Still open */
/* Your processing */
ENDDO /* Still open */
Command parameters *CMD
------------------
SPLF The spooled file name to be checked. If the spooled
file does not exist, TAA9883 is sent as an escape
message.
JOB The qualified job name. An * is the default and
means the current job. If the job does not exist,
TAA9884 is sent as an escape message.
SPLNBR The spooled file number. *ONLY is the default.
*LAST may be specified or a specific spooled file
number in the range of 000001 - 999999.
CHKOPEN An optional parameter to check for whether the
spooled file is in an *OPEN status. The default is
*NO meaning that no checking occurs.
*YES may be specified to cause a check against the
current status of the spooled file. If the status
is *OPEN, TAA9895 is sent as an escape message.
There are some exception conditions where the
spooled file will not be in a status of *OPEN, but
will not be closed by a program. For example, if
the spooled file is SCHEDULE(*IMMED), the spooled
file may have a status of *WRITING even though the
program is still writing records to the spooled
file. Similarly, a status of *MESSAGE may indicate
the program has not closed the file.
