Create the tsmsched service:

# mkssys -p /usr/bin/dsmc \   /* Absolute path to the subsystem executable
                                 program. */
         -s tsmsched \        /* Name that uniquely identifies the subsystem. */
         -u 0 \               /* User id for the subsystem. */
         -a sched \           /* Arguments to be passed to the command. */
         -e /dev/console \    /* Where the subsystem standard error data is
                                 placed. */
         -i /dev/console \    /* Where the subsys. standard input is routed. */
         -o /dev/console \    /* Where the subsys. standard output is placed. */
         -R \                 /* Subsystem is restarted if the subsystem stops
                                 abnormally. */
         -Q \                 /* Multiple instances of the subsystem are not
                                 allowed to run at the same time. */
         -S \                 /* Subsystem uses the signals communication
                                 method. */
         -f 9 \               /* Signal sent to the subsystem when a forced
                                 stop of the subsystem is requested. */
         -n 15 \              /* Signal sent to the subsystem when a normal
                                 stop of the subsystem is requested. */
         -E 20 \              /* Execution priority of the subsystem. */
         -G tsm \             /* Subsystem belongs to the group specified. */
         -d \                 /* Inactive subsystems are displayed when the
                                 lssrc -a command request is made. */
         -w 20                /* Time, in seconds, allowed to elapse between a
                                 stop cancel (SIGTERM) signal and a subsequent
                                 SIGKILL signal. */

Check the service's configuration:

# lssrc -S -s tsmsched
#subsysname:synonym:cmdargs:path:uid:auditid:standin:standout:standerr:action:multi:contact:svrkey:svrmtype:\
 priority:signorm:sigforce:display:waittime:grpname:
tsmsched::sched:/usr/bin/dsmc:0:0:/dev/console:/dev/console:/dev/console:-R:-Q:-S:0:0:\
 20:15:9:-d:20:tsm:

Or directly querying the ODM internal database:

# odmget -q subsysname=tsmsched SRCsubsys

SRCsubsys:
        subsysname = "tsmsched"
        synonym = ""
        cmdargs = "sched"
        path = "/usr/bin/dsmc"
        uid = 0
        auditid = 0
        standin = "/dev/console"
        standout = "/dev/console"
        standerr = "/dev/console"
        action = 1
        multi = 0
        contact = 2
        svrkey = 0
        svrmtype = 0
        priority = 20
        signorm = 15
        sigforce = 9
        display = 1
        waittime = 20
        grpname = "tsm"

Start the new service:

# startsrc -s tsmsched

Launch the TSM scheduler at run-level #2:

# cat << EOF > /etc/rc.d/rc2.d/Stsmsched
#!/usr/bin/env ksh
###############################################################
# name: {K|S}tsmsched

  echo "Usage: $0 {start|stop}"
  exit 1

Comments

To remove a subsystem, use

# rmssys -s Subsystem

Trouble:

  Yes, this is the way we start TSM since 2003 in AIX - but have you ever tried to get the dsmcad daemon defined as a functional subsystem. \\

It can be defined without problems - but a stopsrc isn't possible ..

    mkssys -s tsmcad -p /usr/tivoli/tsm/client/ba/bin64/dsmcad -u 0 -S -n 15 -f 9 -G tcpip -R -o /dev/null -e /dev/null -Q

  start is successful:

    :/usr/tivoli/tsm/client/ba/bin: startsrc -s tsmcad
    0513-059 The tsmcad Subsystem has been started. Subsystem PID is 12189786.

    processes running

    ps -ef | grep dsm
    root 7667928 1 15 09:45:05 - 0:00 /usr/tivoli/tsm/client/ba/bin64/dsmcad
    root 11337922 1 0 09:44:52 - 0:00 /usr/tivoli/tsm/client/ba/bin64/dsmcad
    root 11796702 1 0 09:44:58 - 0:00 /usr/tivoli/tsm/client/ba/bin64/dsmcad

    but stop:

    stopsrc -s tsmcad
    0513-004 The Subsystem or Group, tsmcad, is currently inoperative.
