Paging partition arbitration of paging devices to shared memory partitions

A computer program product for establishing at least one paging partition in a data processing system, the computer program product comprising:

• computer usable program code configured to receive a user selection to allocate a subset of physical memory to a shared memory pool;
• computer usable program code configured to reserve up to the subset of physical memory for use in the shared memory pool;
• computer usable program code configured to configure at least one logical partition as a shared memory partition;
• computer usable program code configured to assign a paging partition to the shared memory pool;
• computer usable program code configured to determine whether a user requests a redundant assignment of the paging partition to the shared memory pool;
• computer usable program code configured to assign a redundant paging partition to the shared memory pool, responsive to a determination that the user requests a redundant assignment;
• computer usable program code configured to assign a paging device to the shared memory pool;
• and
• computer usable program code configured to transmit at least one paging request to a virtual asynchronous services interface configured to support a paging device stream.

A data processing system comprising:

• a bus;
• a storage device connected to the bus, wherein computer usable code is located in the storage device;
• a communication unit connected to the bus;
• and
• a processing unit connected to the bus, wherein the processing unit executes the computer usable code for establishing at least one paging partition in a data processing system, the processing unit further executes the computer usable code to receive a user selection to allocate a subset of physical memory to a shared memory pool;
• reserve up to the subset of physical memory for use in the shared memory pool;
• configure at least one logical partition as a shared memory partition;
• assign a paging partition to the shared memory pool;
• determine whether a user requests a redundant assignment of the paging partition to the shared memory pool;
• assign a redundant paging partition to the shared memory pool, responsive to a determination that the user requests a redundant assignment;
• assign a paging device to the shared memory pool;
• and transmit at least one paging request to a virtual asynchronous services interface configured to support a paging device stream.
