    This request is a duplicate of RFE 113689.

    The following work-around is included in this RFE as well.

    To direct a table function to be run on a remote system, add a three-part reference to a table on that system. Here is an example. Replace RMTDB with the system you want to access.

    select current server, h.*
    from table(qsys2.history_log_info()) h
    where exists
    (select 1 from RMTDB.sysibm.sysdummy1);

    Hi Rob.

    Your problem can (temporarily) be solved by using a WHERE clause, according to a tweet by Scott Forstie:

    If you code a table based 3-part name in your WHERE clause, your UDTF invocation will execute on the target RDB.
    -- Example:
    select current server, h.* from table(qsys2.history_log_info()) h
    where exists (select 1 from rmtdb.sysibm.sysdummy1);

    Check the tweet from Scott:

    I support your RFE - but it seems like it's coming (at least that's how I read Scott's answer to my question in the tweet...)
