Hi,
You need to adjust your pctfree and pctused to reflect the "activity" in your tables.
In addition to that you can do a reorganisation (export / import) when nescessary.
Row chaining is a symptom of updates that cannot be handled whitin the current storage definitions.
When a row is created it get a rowid that is physical, if that row later is updated and there isn't sufficient room for the update you got chained row(s)
