How to restrict log file size in 10.2 pdmlink

Hi ..

I have windchill pdmlink 10.2 m010 installed.  it looks like this version has only one log file i.e. log4j copared to erlier versiosn.

in earlier version we used to have three  2  excluding GC file for each MS. i.e. MS.log and log4j

I used same manage file property in 10.2 to restrict the file size to 9mb but did not worked

so is there any other property for 10.2 ..  let me know how to restrict the file size in 10.2
