I believe it only keeps 30 days worth of summary data. I'm not sure you
can change this - or that you'd want to. Your database will grow.
However, the data in the summary table is very valuable for later
analysis. What I do is every day, shortly after midnight, run a SQL
SELECT to extract the previous day's summary table entries, and save
that in a plain flat tab-delimited disk file. I use a separate file for
each day, keep them forever, and combine them into a temporary file only
when I want to analyze data across a number of days. Then I analyze this
data afterwards using the SPSS statistical package (an IBM product)
which produces much, much nicer reports and charts than you could
possibly do with even the most ingenious SQL SELECT syntax. Any other
general-purpose statistical package that you happen to have such as SAS
would also work.
This also removes the processing load of data analysis from the TSM
server and its all-important database, onto another system such as my
