Specifies, in megabytes, how much virtual storage should be fixed for writing to and reading from disk storage pool volumes during the current server session. The default value is 0. A larger value may have better performance throughput to the Virtual Storage Access Method (VSAM) disk, but it also requires more memory. When you specify a value from 1 to 64, TSM also fixes the buffers for writing to the database and recovery log.
