Any RTFMS etc appreciated ...... This is usually from one of two reasons: 1) There is not enough space to attach the segment, 2) There is already a segment for this SHMID that doesn't match the Lock Manager version. Look to see if there is already a segment ( using ipcs ) with the SHMID that you are using ( default is 0x1327 ). If so, remove it and try again. If that doesn't help, try increasing the attach address. You can do this by setting a value for DEFSIZE. This variable MUST be in bytes and MUST be on one MB boundaries. The default for this is one megabyte. Try increasing this to two or three megabytes. Remember to leave NSEGS unset ( or set to 0 ). Hope this helps, if not, remember that UNIFY has a no charge information line that might be able to help you further. There is a 10 minute limit on the phone calls, but is a very good source for help when you don't have a support contract. -- Mark E.
