ORA-02041: client database did not begin a transaction

Hi,

Environment:

w2000,
..net fw 1.1,
Oracle server 8.1.7
Oracle client 8.1.7, (trying 9 as well)

I am trying to call stored procedure on oracle server via
System.Data.OracleClient. Procedure do simple job: fill its output
parameters from select statement and return. Unusuall thing is there
is db link to other stored procedure inside procedure I call,
something like this:

<procedure I call from .net>
<call to other procedure with same parameters in other db (db
link)>
<called procedure do some select into output params>
<end>

Procedure I call does not containt anything instead of that link to
other sp.

I've read google and trying almost all with no result.

Please help !
