pscbo_stats v2 - error while implementing

I am getting the following error when trying to implement pscbo_stats v2 on PeopleTools 8.52.05, Oracle 11.2.0.3 environment.

SQL> EXEC pscbo_stats.quick_config;
BEGIN pscbo_stats.quick_config; END;

ERROR at line 1:
ORA-00932: inconsistent datatypes: expected NUMBER got LONG
ORA-06512: at "SYSADM.PSCBO_STATS", line 1263
ORA-06512: at line 1

It may be due to the mismatch in the field data type in PSDDLMODEL and pscbo_psddlmodel_history shown below. Anybody get similar errors?

desc PSDDLMODEL
Name Null Type
--------------- -------- ----------
STATEMENT_TYPE NOT NULL NUMBER(38)
PLATFORMID NOT NULL NUMBER(38)
SIZING_SET NOT NULL NUMBER(38)
PARMCOUNT NOT NULL NUMBER(38)
MODEL_STATEMENT NOT NULL LONG()
