I installed IBM Data Studio 4.1 and Connect to DB2 z/OS 10 Version, Input SQL and Open visual Explain. in this plan , Include IXAND and IXOR, SORTRID. I was confused about these attributes values. because I view all Plan Tables, cannot find same attribute values about Node "IXAND", "IXOR", "SORTRID".
Please see my attachment file IXAND.PNG.
