  • 1.  Extracting the SMS group description using ops/MVS and Address Sysview

    Posted Mar 22, 2022 11:00 AM
    I am trying to extract the SMS Group description from the SMSGROUP panel via an Ops/MVS Ops/EXEC as follows:

    this = opsinfo('program')

    sysvcmd = 'SMSGROUP;',
    'SEL NAME eq 'smsGroup';',
    'XVEXTRAC DATA Type type.;',
    'XVEXTRAC DATA Capacity capacity.;',
    'XVEXTRAC DATA Free free.;',
    'XVEXTRAC DATA Used used.;',
    'XVEXTRAC DATA Used% usedPct.',
    'XVEXTRAC DATA Description desc.'

    say this" returned "desc.0" description lines"

    but desc. is not being populated.

    Is it not being returned or do I have the wrong column name, and if so how do I find the correct one?

    Thanks,

    Steve

    Hi Steve,

    For the Sysview Rexx execution..
    When i check the XVEXTRAC help screen the sample Rexx shows another syntax as you used in your Rexx program.
    See here the sample:

    ....+....1....+....2....+....3....+....4....+....5....+....6
    /* REXX */
    ADDRESS 'LINK' 'GSVXRXAA'
    ADDRESS 'SYSVIEWE'
    'COMMAND(ACTIVITY) STACK(NO)'
    'COMMAND(XVEXTRAC DATA jobname jobname.)'
    DO i = 1 TO jobname.0
    SAY "jobname." || i jobname.i
    END
    'COMMAND(END)'
    EXIT

    Could you please change your Rexx according the sample and see if it works.

    Best regards
    Hennie Hermans

    Hi Hennie,

    OK - found the error thanks to your prompt. I'd missed off the ';' from the end of the line
    'XVEXTRAC DATA Used% usedPct.', which is necessary as this is a series of stacked commands, so what was happening was I was sending the string :

    SMSGROUP;SEL NAME eq 'smsGroup';XVEXTRAC DATA Type type.;XVEXTRAC DATA Capacity capacity.;XVEXTRAC DATA Free free.;XVEXTRAC DATA Used used. <SEMI_COLON NEEDED HERE> XVEXTRAC DATA Used% usedPct. <AND HERE> XVEXTRAC DATA Description desc.

    to Sysview as a command and the XVEXTRACs for both Used% and Description weren't part of the 'SMSGROUP' command and so the variables weren't being populated (I'd missed the fact that usedPct was also not populated).

    Regards,

    Steve

    Just as a follow-up Hennie, is the FIELDS command on any Sysview display the definitive list of fields than can be extracted via XVEXTRAC?

    Also yes - I've hit the max command length using a stacked command like this so I've got some code somewhere that loops around a list of commands and issues them separately, which seems to get around that problem.

    Thanks,

    Steve

    Hi Steve,
    Check our screen format... Is it DEFAULT?

    The DEFAULT screen format of the SMSGROUP contains the fields Description and Used%... 

    See here:

    Hi Steve,

    I believe that this code might work for you.

    /* REXX */
    Address 'SYSVIEWE'                                                      /* Set address env */
    'COMMAND(SET APISTACK OFF)'                                /* Set EDQ off       */
    'COMMAND(SMSGROUP)'                                             /* Sysview command */
    'COMMAND(XVEXTRAC DATA Name sms_group.)'     /* Extract Name to stem */
    'COMMAND(XVEXTRAC DATA Type sms_type.)'         /* Extract Type to stem */
    'COMMAND(XVEXTRAC DATA Free sms_free.)'           /* Extract Free to stem */
    'COMMAND(XVEXTRAC DATA Used sms_used.)'         /* Extract Used to stem */
    'COMMAND(XVEXTRAC DATA Used% sms_usedPct.)' /* Extract Used% to stem */
    'COMMAND(XVEXTRAC DATA Description sms_desc.) /* Extract Description to stem */
    Select
       When RC > 4 Then Do                            /* if RC > 4 */
          Say 'API command error RC = 'RC      /* Then say so */
          Say SYSV_MESSAGE                            /* dispaly sysv msg */
          Signal PGM_EXIT                                   /* Get Out */
      End   /* When RC > 4 */
      When RC > 0 Then ,                                 /* if RC > 0 */
          Say SYSV_MESSAGE                            /* display sysv msg */
      Otherwise NOP                                         /* No OP */
    End   /* Select */
    Do i = 1 to sms_name.0                               /* Loop through stem var */
       Say 'SMS Group = 'sms_group.i' Type = 'sms_type.i' Free = 'sms_free.i' Used = 'sms_used.i
       Say 'Used % = 'sms_usedPct.i' Descr = 'sms_desc.i
    End
    PGM_EXIT:
    'COMMAND(End)'                                         /* end Sysview session*/
    Return RC


    Now if you wanted a specific SMS Group you could add a SELECT command before the XVEXTRAC commands like;
    'COMMAND(SELECT NAME EQ STANDARD)'           /*limit display to group STANDARD */

    Also in CA OPS OSF servers, there is no requirement to ADDRESS 'LINK' 'GSVXRAA'), but this would be required in a TSO REXX.

    Also the online help for XVEXTRAC is very detailed and helpful.
