IXC582I

Explanation
A structure was allocated in a coupling facility with an actual allocation
     size that may exceed the size specifications requested by the CFRM active policy definitions at
     the time of structure allocation. The actual allocation size is compared to
      the policy INITSIZE if specified or the policy size if INITSIZE is not specified. The size
      discrepancy may result from structure allocation "by counts" which allocates the structure
      with the desired counts of structure objects (entries, data elements, EMCs), regardless of the
      resulting structure size. Another example of a size discrepancy results when the IXLCONN
      STRSIZE specified is greater than the specified policy INITSIZE.
In the message
     text: strname
The name of the allocated structure.
alloctype
Method of structure allocationcounts
The structure was allocated by target counts.
size/ratio
The structure was allocated by target structure size and ratios.

physver1
First half of the physical version number of the alocated instance of the structure.
physver2
Second half of the physical version number of the allocated instance of the
        structure.
strtype
One of the following:list
The structure is an unserialized list structure.
cache 
The structure is a cache structure.
serialized list
The structure is a serialized list structure.
lock
The structure is a lock structure.

cfname
The name of the coupling facility in which the structure has been allocated.
allocsize
The allocated size of the structure.
u
The integer size unit specification. One of the following: K (kilobytes)
M (megabytes)
G (gigabytes) 
T (terabytes)

Note: The size unit displayed may be converted to the largest size unit that can be
         used to represent the size and avoids any rounding. For example, a
          allocsize of 1048576K may be converted to a
          allocsize of 1G for the purpose of messages. A
          allocsize of 120000K will not cause the displayed size to be converted
         because it is not an even multiple of megabytes, gigabytes, or terabytes.

maxsize
The maximum size of the structure as determined at allocation time based on the CFRM
        policy and environmental factors.
maxscmsize
The maximum amount of storage-class memory the structure can use as determined at
        allocation time based on the CFRM policy and environmental factors.
policysize
The CFRM active policy defined SIZE of the structure.
policyinitsize
The CFRM active policy defined INITSIZE of the structure. If
        INITSIZE is not specified, this value will be zero.
policyminsize
The CFRM active policy defined MINSIZE of the structure. If not
        specified, the default value will be displayed. When ALLOWAUTOALT(YES) is specified, MINSIZE
        defaults to 75% of the INITSIZE value (or the SIZE value if INITSIZE is not specified).
        Otherwise, MINSIZE defaults to zero.
policyscmmaxsize
The SCMMAXSIZE for the structure as specified or defaulted to in the CFRM active policy.

ixlconnstrsize
The STRSIZE requested by the CF structure exploiter on the IXLCONN
         macro. If not specified by the exploiter, this value will be zero. This value will
        also be zero when the structure is being allocated by a system-managed process rather than
        directly by an exploiter using the IXLCONN macro.
entrycnt
The total count of entries allocated for the structure.
elementcnt
The total count of data elements allocated for the structure. Not displayed when the
        count is zero.
emccnt
The total count of event monitor controls (EMCs) allocated for the strucutre. Event
        monitor controls are only present in list structures that support certain types of
        monitoring. Not displayed when the count is zero.
lockentries
The total number of lock entries. Only displayed for lock or serialized list
        structures.
emaxscmentrycnt
Estimated maximum number of entries that can be stored in the storage-class memory
        associated with this structure. Only displayed if the structure is allocated with support
        for storage-class memory.
emaxscmelementcnt
Estimated maximum number of elements that can be stored in the storage-class memory
        associated with this structure. Only displayed if the structure is allocated with support
        for storage-class memory.
entratio
The entry portion of the entry-to-element ratio. Zero for a structure without
        entries.
elemratio
The element portion of the entry-to-element ratio. Zero for a structure without
        data.
emcstgpct
The percentage of structure storage being used for Event Monitor Controls (EMC) objects.
        Event monitor controls are only present in list structures that support certain types of
        monitoring. Not displayed when the percentage is zero.

One of the following:ALLOCATION SIZE EXCEEDS CFRM POLICY DEFINITIONS
The structure allocation size exceeds the size indicated by CFRM active policy
           definitions allowing for rounding up to a multiple of the CF storage increment size. The allocation size is compared to the policy INITSIZE if specified or the
            policy size if INITSIZE is not specified.
ALLOCATION SIZE IS WITHIN CFRM POLICY DEFINITIONS
The structure allocation size is within the size indicated by CFRM active policy
           definitions allowing for rounding up to a multiple of the CF storage increment size.The allocation size is compared to the policy INITSIZE if specified or the
            policy size if INITSIZE is not specified.

System action
System processing continues. The system writes the message to the hardcopy
     log.

System programmer response
If the allocation size of the structure exceeds
     CFRM policy definitions, consider whether it is necessary to update the CFRM policy to increase
     the requested structure size to the actual allocated structure size as indicated by this
     message.

    A structure allocated with support for storage-class memory may be 
      allocated with a structure size that exceeds CFRM policy definitions in order to avoid an 
      INVALID TARGET STRUCTURE COUNTS condition. Only system-managed rebuild allocation may be able 
      to avoid that condition. Consider using the CF Sizer tool, available on the Parallel Sysplex 
      website http://www.ibm.com/systems/support/z/cfsizer, for help in determining structure SIZE, 
      INITSIZE, and SCMMAXSIZE attributes.
If the structure has increased in size 
       as a result of rebuilding or duplexing the structure into a CF at a different (higher) 
       CFLEVEL than the one in which the
     original structure is allocated, and you intend to continue to use the higher CFLEVEL in the
     future, update the CFRM policy size definitions to be in line with the allocated structure size
     indicated by this message. Failure to do so might result in the structure being allocated with
     an inadequate structure size, or possibly not being allocatable at all, when the structure is
     initially allocated in the future. This might result in system, subsystem, or application
     outages.
If the structure has increased in size when rebuilding or
     duplexing the structure into a CF at the same CFLEVEL in which the original structure is
     allocated, there may be no need to update the CFRM policy definitions to reflect the larger
     allocated structure size indicated by this message.
Similarly, when the
     structure has been allocated larger than the policy INITSIZE value because the structure
     exploiter has requested a larger IXLCONN STRSIZE value, there is no need to update the CFRM
     policy definitions to reflect any size-related changes.
Ensure that the
     increased CF storage allocation for the structure can be accommodated not only within the
     current CF, but also in any other CF images in which the structure is eligible to be
     allocated.
