ArcSDE for SQL Server only - sdedbtune "alter", "insert" & "import" options are wrongly resetting all default parameters to default values if they are not explicitly listed in the input file.
Follow these steps. 1. Export entire DBTUNE table to a text file using sdedbtune -o export2. Use a text editor to edit the parameter values you want to modify in the text file.3. Import the entire text file using sdedbtune -o import.
