SysAdmin ToDo List
---------------------

Weekly 

Use jobschd to check for "Needs Recovery" Jobs in Waiting Queue: F7, Show, All Users 

Scan $LAWDIR/system/ladb.log and $LAWDIR/system/latm.log for errors. 

Check for program compile errors: 
        find $LAWDIR/ -name "*.err" 

Clean up the joblog directory: 
        If there are not too many files: 
                rm $LAWDIR/system/joblog/lapm.* 
        If there are many files (or just to be safe): [For extra safety, make sure this command is NOT run by root.] 
                find $LAWDIR/system/joblog -name "lapm.*" -print | xargs rm 

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

As Necessary
Remove coredump files: 
    rm core 
    find /dirname -name core -exec rm {} \; (slow) 
    find /dirname -name core -print | xargs rm (faster) 

    Or in the users login profile set the core file size to 0 
       ulimit -c 0 

deljobhst =  see scripts referenced at top of page 

rm lawson.log = remove FTP log files  

integ =      to check db file integrity; long run time 

rebuild -f = to rebuild db files as a result of error msg "file unsafe - rebuild" 

cobcmp <pline> systemcode = if a program dies because of a timestamp mismatch 

dmpdict  =   to dump a file description from the dictionary. 
             Useful when you are unsure if your are on SQL or ladb; 
             Do a find on "Location" 

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