Hi
I am currently trying to port an application from a sun sparc station
to SCO ODT UNIX. I seem to get some weird run time core dumps. I
talked to the orginal authour of the code, and was told that this
might because my system is running out of swap space?
HOW BIG SHOULD MY SWAP BE? I have 8megs of ram
ARE THERE ANY TOOLS TO HELP ME MANAGE / MONITOR MY SWAP SPACE?
thanks in advance Andy

Unlike the 3b2 and other machines the 386 in unforgiving on null pointers. Perhaps there is minor bug or something in the code. >HOW BIG SHOULD MY SWAP BE? I have 8megs of ram > On UNIX System V/386 Release 3.2 (I believe SCO UNIX is a variant of this) SWAP should be about 15% of disk or perhaps in your case 12 meg (1.5 of ram). As a side note, SVR4 would required twice ram from swap but thats a different story. >ARE THERE ANY TOOLS TO HELP ME MANAGE / MONITOR MY SWAP SPACE? > You can run: # swap -l # sar -r Look at the book: System Performance Tuning by O'Reilly and Associates, Inc pages 118 -> >thanks in advance Andy > Sincerely, John Urban
