DB2TOP EXITS WITHOUT SHOWING ANY DATA WHEN PLAYING WITH COLLECTED FILE IN REPLAY MODE |

DB2TOP exits without showing any of the data collected:

Problem is because the stream size limit is 100M/hour.
The above output show that db2top is estimating at
[03:51:05] the collection rate is 189.1M/hour and db2top
collected 18.3M in
about 10 minutes. |

| Local-Fix: |
If problem happens in replay mode, increase stream size by
adding streamsize=###M to .db2toprc file and rerun.
To estimate the size to of 'streadmsize' to use in .db2toprc use
the info from the previous attempt.
In the example above it shows 18.3M within 10 minutes.
Estimate the streamsize by taking the 18.3M * 6=110M/hour. Since
the volume
of captured snapshot data can flucturate leave a big margin
size. Increase 4-5 times the
size estimated. In this case set streamsize=500 in .db2toprc
file |
