Federated DB, access to remote sequence

[Joerg Ammann]

hello,

we are using:
- DB2 UDB V 8.1 FP-6 on LINUX as (local) federated DB
- DB2 UDB V 7.2 on AIX as datasource

we try to move part of an application (most of the tables) von AIX to
LINUX and acess a few remaining tables (on AIX) via the "federated DB"
feature.

setup (SERVER, WRAPPER, NICKNAMES, etc.) worked and select, insert on
the remote (AIX) tables works fine.
now i have the problem that i must access (get the NEXTVAL) of a
sequence which is remote defined (because i need it in a local
trigger, i dont't think that i can use the PASSTHRU option).

i next tried to define a remote function (which gets the NEXTVAL) and
map a local function to it.

didn't worked either (see below).
anybody, any ideas ? how to do it ?
