Running OMVS Commands in Batch
The BPXBATCH command can be used from TSO or batch to run an OMVS program
or shell command. Here is an example of running OMVS commands in batch
with the output going to SYSOUT:
<![CDATA[
//RUNSHELL EXEC PGM=BPXBATCH,PARM='sh id'
//STDOUT DD PATH='/tmp/bpxmsgs',
// PATHOPTS=(OCREAT,OTRUNC,OWRONLY)
//RUNSHELL EXEC PGM=BPXBATCH,PARM='sh ls -l'
//STDOUT DD PATH='/tmp/bpxmsgs',
// PATHOPTS=(OAPPEND,OWRONLY)
//PRINT EXEC PGM=IKJEFT01,REGION=2000K,DYNAMNBR=20,TIME=(,10)
//JESOUT DD SYSOUT=*,RECFM=V,LRECL=256
//TPSTDOUT DD PATH='/tmp/bpxmsgs',
// PATHOPTS=ORDONLY
//SYSTSPRT DD SYSOUT=*
//SYSTSIN DD *
OCOPY INDD(TPSTDOUT) OUTDD(JESOUT) TEXT
BPXBATCH PGM /bin/rm -f /tmp/bpxmsgs
]]>
Two shell commands are run:
An HFS file /tmp/bpxmsgs is allocated to standard output which receives
the messages from each command. The PATHOPTS for the first step specify
that this file will be created if it doesn't exist or overwritten if it
does. The second step appends to this existing file. The final step
copies the HFS file to SYSOUT and then deletes it. Note that BPXBATCH can
be used from TSO in batch or invoked directly (PGM=).
If you are running V2R9 and up, you can use BPXBATSL instead of
BPXBATCH to run a program. There is less execution overhead associated
with BPXBATSL.
The TSO OSHELL EXEC allocates an HFS file, runs a shell command and
then copies the result to SYSOUT. Here is an example:
<![CDATA[
//RUNOSH EXEC PGM=IKJEFT01,REGION=2M
//SYSEXEC DD DSN=SYS1.SBPXEXEC,DISP=SHR
//SYSTSPRT DD SYSOUT=*
//SYSTSIN DD *
OSHELL id
//RUNOSH EXEC PGM=IKJEFT01,REGION=2M
//SYSEXEC DD DSN=SYS1.SBPXEXEC,DISP=SHR
//SYSTSPRT DD SYSOUT=*
//SYSTSIN DD *
OSHELL ls -l
]]>
The OSHELL EXEC generates a (hopefully) unique HFS file name for standard
output.
