It may be occurred where the system calls DBMS_SQL.* routines and federated procedures. There are two potential workarounds. - It should not happen by avoiding to call DBMS_SQL routines and federated procedures same timing. - It should not happen if creating a DARA wrapper with DB2_FENCE='Y' and use federated procedures with it only. And also avoiding to call DBMS_SQL.* routines with this wrapper. | |
