DB2 z/OS storede procedure - IN parameter XML

Hello,
we are developing stored procedures that should have IN parameter XML, but this doesn't work - we get SQLCODE = -20060, ERROR: UNSUPPORTED DATA TYPE XML ENCOUNTERED IN SQL PARAMETER. In book we found that VARCHAR could be used instead of XML, but VARCHAR has limit of 32000 bytes and our XMLs are larger than this (we want to store this XML from IN parameter into table with XML column).
Does anyone have any experience with this, how to handle this, using CLOBs...?


Thanks, Ivana
