  • Closed as program error.

Error description

  • If the call statement is invoked by a DRDA client (eg zOS DB2 V7
    client) using SQLAM level <  7, LUW server (V8 and V9) does not
    block cursors in the resultset.
    Note- Even though the restriction is applicable for stored
    procedures written in any of the supported languages (eg cli,
    java, .net, PSM etc). The problem using this APAR is fixed only
    for stored procedure written in SQL ( PSM) language. To fix the
    performance issue for stored procedure written in any other
    language  upgrade zDB2 client to V8 or higher level.
