Legend
- Maximum number of CPs
- Indicates the maximum number of CPs that can be used by a coupling facility logical partition.
- Storage increment
- Indicates the granularity with which storage allocation requests are rounded, to the amount shown in the table for a particular CFCC level.
- Structure ID limit
- Cache and list structure ID. Effectively, this limit defines the maximum number of coupling facility structure instances that a coupling facility at this level may contain.
- Retry buffer limit
- Retry buffer range upper limit.
- Facility information
- This area contains coupling facility control code release and service level information
- Maximum list element characteristic
- The size of a list structure list element in bytes equals 256 * (2 ** list element characteristic), for example, 256 * (2**4) = 4K.
- Maximum lock table entry characteristic
- The size of a lock table entry in bytes equals 2 ** lock table entry characteristic.
- User identifier limit
- The maximum number of users and list notification vectors that can be attached to a list structure.
- Maximum data area element characteristic
- The size of a data area element in bytes equals 256 * (2 ** data area element characteristic, for example, 256 * (2**4) = 4K).
- Local cache identifier limit
- The maximum number of local caches that can be attached to a cache structure.
- Storage class limit
- Storage classes are in the range 1 to the value shown in the table.
- Castout class limit
- Castout classes are in the range 1 to the value shown in the table.
- Notification-Delay Limit (NDL)
- The maximum time delay value that can be specified for a list structure's notification delay. The notification delay is the time delay between the initial notification performed to a single selected user in response to a monitored object (sublist, list, or key-range) becoming non-empty, and the subsequent notification(s) that are performed to the remaining monitoring users.
