If you use AUTOGEN, add lines to your MODPARAMS.DAT file like `LRPCOUNT=50' for each of the values you need to change and rerun AUTOGEN. I recommend that you choose a number about 10% larger than what you see with SHOW MEMORY. When you crank these values up, you may also have to crank up NPAGEDYN as well. The way VMS allocates LRP's and other data structures is to pull them off of a linked list until it is empty. Then it uses regular non-paged pool to allocate the new ones. This slows down your system and causes fragmentation in the non-paged pool. It really does not save you anything to keep the number of LRP's and other structures less than what your system uses, VMS will get that storage anyway. --Mark
