PRIVATE

The PRIVATE (PRI) service summarizes virtual storage allocations for private storage in an address space and displays an overview of subpool allocations within a private address space.

Use the PRIVATE service to

  • display allocated storage and fragmented free space by subpool and key
  • debug applications that use excessive private storage
  • tune virtual storage-constrained systems
  • monitor virtual storage use within an address space

asi

address space instance; see Identifying-address-spaces for more information

LSQA

detailed report of allocations in the Local Systems Queue Area (LSQA), which consists of subpools 203-205, 213-215, 223-225, and 253-255

spid

three-digit decimal subpool identifier in the range between 0 and 255

TCB

summary of the storage allocated by all tasks in the address space

address

address of the TCB for which you want to display a detailed report of storage allocations

HIGH

summary of subpools located in private high storage

LOW

summary of subpools located in private low storage
