Automatic structure alter parameters

Use these parameters to modify the conditions under which the server attempts an automatic alter when the structure becomes nearly full.

For information about the structure alter process, see Coupling facility data table server automatic structure alter.

ALTERELEMMIN={100|number}

specifies the minimum number of excess elements that must be present to cause the server to issue an automatic alter to convert those elements to entries.

The valid range is from 0 to 999999999.

ALTERELEMPC={5|number}

specifies the minimum percentage of excess elements that must be present to cause the server to issue an automatic later to increase the proportion of entries.

The valid range is from 0 to 100 per cent.

ALTERENTRYMIN={100|number}

specifies the minimum number of excess entries that must be present to cause the server to issue an automatic alter to convert those entries to elements.

The valid range is from 0 to 999999999.

ALTERENTRYPC={5|number}

specifies the minimum percentage of excess entries that must be present to cause the server to issue an automatic alter to increase the proportion of elements.

The valid range is from 0 to 100 per cent.

ALTERMININTERVAL={00:10|hh:mm}

specifies the minimum time interval to be left between automatic structure alter attempts when the structure is nearly full (above the element or entry warning level). This is to prevent excessive numbers of alter attempts to try to optimize space when the structure is nearly full.

The valid range is from 00:00 to 24:00.

This keyword can be abbreviated to ALTERMININT.
