Error description

  • Using db2top collector mode (-C) stops with error if output file
    exceeds 2GB size.
    
    Following is an example of the command line output of the db2top
    utility:
    
    db2top -d sample -C -i 30 -m 120
    [13:23:11] Starting DB2 snapshot data collector, collection
    every 30 second(s), max duration 120 minute(s), max file
    growth/hour 500.0G, hit <CTRL+C> to cancel...
    [13:23:13] Overridding previous occurence of
    'db2snap-sample-Linux64.bin'
    [13:23:43] 26.7M written, time 32.835, 2.9G/hour
    [13:24:15] 53.5M written, time 64.587, 2.9G/hour
    <...>
    [14:10:52] 1.8G written, time 2861.044, 2.3G/hour
    [14:14:16] 1.9G written, time 3065.507, 2.3G/hour
    [14:15:47] 16777215.9T written, time 3156.310, 16777215.9T/hour
    Warning: The current snapshot collection was skipped, because:
    The estimated file growth/hour, 2305873.2T , is greater than the
    max file growth/hour: 500.0G
    Therefore, the collected file, 'db2snap-sample-Linux64.bin' ,
    may not be usable. Here are some recommendations:
    1) Increase the max file growth/hour by specifying 'streamsize'
    parameter in .db2toprc to at least: streamsize=2305873.2T
    2) Or increase the snapshot collection interval time by
    specifying option: -i
