Subj:   Re: Unix Script calling showlocks
 
From:   Yumoto, Masami

I think you can use 'cnsrun'.

     man cnsrun
       cnsrun - Runs a PDE Console Subsystem application via
                      single command line or an input file

     [Sample script]
     1) showlocks.sh

     ------------------------------------

     #!/bin/bash
     #set -x
     # Must be run as root
     LOGFILE=/tmp/showlocks.txt
     LOCK_RESULTWK=/tmp/showlock_reswk.txt
     LOCK_RESULTF=/tmp/showlock_res.txt
     /usr/pde/bin/cnsrun -utility showlocks -file /dev/null -debug 1 |
     /usr/bin/tee ${LOGFILE}
     if [ "$?" -ne "0" ]
     then
              echo "showlocks abnormal end" | /usr/bin/tee -a ${LOGFILE}
              exit 1
     else
              echo "showlocks normal end" | /usr/bin/tee -a ${LOGFILE}
     fi
     LOCK_RESULT=`./find_lockinf.pl ${LOGFILE} | /usr/bin/tee
     ${LOCK_RESULTWK}`
     /bin/cat ${LOCK_RESULTWK} | \
        /usr/bin/grep -v "AMP Number" | \
        /usr/bin/grep -v "There are currently no host utility locks in the
     DBC" | \
        /usr/bin/grep -v "ShowLocks Processing Complete" | \
        /usr/bin/sed '/^$/d' | /usr/bin/sed '/^ $/d' | /usr/bin/tee
     ${LOCK_RESULTF}
     GREP_RESULT=`/bin/cat ${LOCK_RESULTF} | /usr/bin/wc -l`
     if [ "${GREP_RESULT}" -eq "0" ]
     then
              echo "Locking tbl nothing" | /usr/bin/tee -a ${LOGFILE}
     else
              echo "Locking tbl exists" | /usr/bin/tee -a ${LOGFILE}
              /bin/cat ${LOCK_RESULTF} | /usr/bin/tee -a ${LOGFILE}
     fi
     exit 0

     ------------------------------------

     2)  find_lockinf.pl

     ------------------------------------

     #!/usr/bin/perl
     # run as root
     while (<>) {
          if ( /--AMP Number/ .. /--ShowLocks Processing Complete--/ ){
              print;
              }
     }

     ------------------------------------

Since message format varies depending on Tera version, grep lines or perl script may need some slight modification.

This script spends more than 10 seconds to finish in our environment, I don't know the exact reason.

But anyway it can be non-interactive showlocks.


Hope this helps.
