stale

In a stream definition in an output adapter map file, the stale element identifies a column in the source stream for which the value changes from 0 to 1 if the stream goes stale.

A stream is considered to have gone stale if, for example, one of the stream's data sources is no longer being updated.

Example

<stream name="stream1" >
        <name column="0"/>
        <stale column="3" name="ACVOL_1"/>
        <field column="1" name="DSPLY_NAME" />
        <field column="4" name="BID" precision="47" />
        <field column="5" name="ASK" precision="0" />
        <field column="6" name="TRDPRC_1"/>
        <field column="7" name="ACVOL_1"/>
        <constant name="PROD_PERM" value="1"/>
</stream>

This example identifies the third column of stream1 as its stale column. If the stale column is specified, the column value is published and the RIC is marked stale.
