Oracle Sp: Getting System.Data.OleDb.OleDbException: ̸�

[John G]

I have been using Oracle Helper to connect to my oracle 9i Db. When
excute text it works fine, but when I try to execute a store procedure
I get the following error message. I searched everyplace for a
solution.

System.Data.OleDb.OleDbException: ̸�
[OleDbException (0x80004005): ̸�]

System.Data.OleDb.OleDbCommand.ExecuteCommandTextF orMultpleResults(tagDBPARAMS
dbParams, Object& executeResult) +161

Here is my code:
string sql = "ghi.usp_Category_Add";

OleDbParameter[] sp = new OleDbParameter[10];
HttpContext.Current.Trace.Write("Category",
content.ToString());
sp[0] = new OleDbParameter("p_Id", content.Id);
sp[0].OleDbType = OleDbType.Integer;
sp[0].Direction = ParameterDirection.InputOutput;
sp[1] = new OleDbParameter("p_parentId", content.ParentId);
sp[1].OleDbType = OleDbType.Integer;
sp[2] = new OleDbParameter("p_name", content.Name);
sp[2].OleDbType = OleDbType.VarChar;
sp[3] = new OleDbParameter("p_description",
content.Description);
sp[4] = new OleDbParameter("p_priority", content.Priority);
sp[5] = new OleDbParameter("p_url", content.Url);
sp[6] = new OleDbParameter("p_ContentId", content.ContentId);
sp[7] = new OleDbParameter("p_ShowSubMenu",
content.ShowSubMenu);
sp[8] = new OleDbParameter("p_SideMenu", content.SideMenu);
sp[9] = new OleDbParameter("p_user", "john");

OleDbHelper.ExecuteNonQuery(Settings.ConnectionStr ing,
CommandType.StoredProcedure, sql, sp);
content.Id = FormUtils.ConvertInt(sp[0].Value.ToString());
