If this is true, can you then explain the following: when you create swap space on an HP disk drive, you may not change the size without reformatting the disk. I was told that this is because the swapping space is in the old file system and therefore static. If anyone knows how to change the swap size dynamically ( we use SDRC CAD programs that are real swap hogs ) please let me know... (By the by, I am going to take the results of this to HP to update their UNIX SysAdmin course. Seems they are a little out of date...) *************************************************************************** Tony Burzio * The IS life after DEC? * Martin Marietta Laboratories * By golly, you're right! * ***************************************************************************
