action_="allocctrl"

<do action_="allocctrl"> changes the subprocess allocation strategy used by MDB. (Available as of version 10.25)

Note: This has the necessary side effect of clearing MDB's cache (so that all queries will need to be rerun).

Syntax

<dynamic>
    <do action_="allocctrl" 
     method_="def|rr|pack0|pack1" 
     parallelism_="[NUMBER_OF_SUBPROCESSES]"/>
</dynamic>
