DFHCF0432I Table pool statistics for CF structure strname:

Explanation

This message gives a summary of the usage statistics for the table pool list structure. It is issued in response to a coupling facility data table server DISPLAY or PRINT command which includes the POOLSTATS parameter, and may also be produced on the SYSPRINT file during interval statistics if the statistics options include print file output.

The detailed message layout is as follows:

User response

The statistics are described in detail in the DFHCFS6D data area. Pool usage statistics are calculated from information returned by recent coupling facility requests, and are not always very accurate, especially if the relevant information has not been accessed recently by the current server. The number of tables and the number of lists are updated each time the server opens or closes a table, but are not reliably updated at other times. The element and entry counts are updated on successful completion of most types of coupling facility access request.

The individual fields have the following meanings:

  • Structure:

    Size

    Current allocated size of the list structure.

    Max size

    Maximum size to which this structure could be altered.

    Elem size

    Data element size used for the structure.

  • Tables:

    Current

    Number of tables currently in existence.

    Highest

    Highest number of tables at any time (since last reset).

  • Lists:

    Total

    Maximum number of list headers in the structure.

    In Use

    Number currently in use.

    Max Used

    Maximum number in use (since last reset).

    Control

    Number of lists in use for control information.

    Data

    Number of lists in use for table data.

  • Entries:

    Total

    Total entries in the currently allocated structure (initially set at structure connection time and updated on completion of any structure alter request).

    In Use

    Number of entries currently in use.

    Max Used

    Maximum number in use (since last reset).

    Free

    Number of entries currently free (total minus used).

    Min Free

    Minimum number of free entries (since last reset).

    Reserve

    Number of entries reserved for rewrites and server use.

  • Elements:

    Total

    Total data elements in the currently allocated structure (initially set at structure connection time and updated on completion of any structure alter request).

    In Use

    Number of elements currently in use.

    Max Used

    Maximum number in use (since last reset).

    Free

    Number of elements currently free (total minus used).

    Min Free

    Minimum number of free elements (since last reset).

    Reserve

    Number of elements reserved for rewrites and server use.
