(x86 systems only) NPAGEDYN_S2 sets the size of the S2 nonpaged dynamic pool in megabytes. This figure is rounded up to an integral number of pages. NPAGEDYN_S2 establishes the initial setting of the S2 nonpaged pool size, but the pool size can be increased dynamically. To set a value for this parameter, use AUTOGEN initially, and then monitor the amount of space actually used with the DCL command SHOW MEMORY/POOL/FULL. For the benefit of OpenVMS systems with limited physical memory, AUTOGEN logs a warning message in its report if NPAGEDYN_S2 or NPAGEXPVIR_S2 exceed certain percentages of physical memory. AUTOGEN limits its own calculated values for NPAGEDYN_S2 and NPAGEXPVIR_S2. These calculated values are adequate for most systems. If your system requires a larger value, you can override the AUTOGEN calculated values by setting higher values for MIN_NPAGEDYN_S2 and MIN_NPAGEXPVIR_S2 in MODPARAMS.DAT. NPAGEDYN_S2 has AUTOGEN, FEEDBACK, GEN, and MAJOR attributes.
