64-bit MVS storage

64-bit MVS™ storage is available to the operating system to perform region-related services.

For information about 64-bit (above-the-bar) storage in an address space, see Using the 64-bit Address Space in the z/OS MVS Programming: Extended Addressability Guide.

If you run Java™ programs in a region, CICS® uses the 64-bit JVM on z/OS®. 64-bit MVS storage is allocated to each JVM that runs under the control of CICS.

For other CICS facilities that use 64-bit MVS storage, see CICS facilities that use 64-bit storage.
