its a data base file and can not be deleted.
so i want to know how to increase the size of mount point
i am new to unix ,please help me

This is not a task for someone new to unix. But if you want to proceed, you will need a lot more information. A good start is what version of HP-UX? Mountpoint implies filesystem, what type of filesystem? If it's JFS, do you have the Advanced JFS product installed? Which volume manager are you using? I will assume that you are using LVM....so do a vgdisplay on the volume group to get the free extents and the extent size. Multiply these together to get the available space in the volume group. There is a good chance that free extents will be zero...in that case you have allocated all of the space on the disks in the volume group and you will need to acquire more disks...or least another one.
