Dear ,
In the above output for F.LOCKING, it is confrimed that the file F.LOCKING
requires to be resized . When the count of Total Frames (i.e,1950) becomes
more than the Groups Allocated (i.e. 1629) , then the File is said to be
Badly sized.
To Resize , the No of Groups or Frames count must be increased so that the
total size of the frames will be within the limit of the allocated Frame
Size.
New Modulo can be calculated based on the total no of bytes divided by the
frame size currently hold by the file.
total no of bytes = 16457728
current frame size = DIV(9840241,1950)
= 5046 bytes
New Modulo = total no of bytes / current frame size
= 3261
Using jrf utility , it has to be re-sized.
Regards,
Srinivas Yadav.
