Obj_Header Information

otid—object type identifier (otid). Identifies the object type. An otid must be unique for every installation. Because this identifier cannot be changed after installation time, each chosen name must be unique. For example, begin with the ptid of the tool that implements the otype. The otid is limited to 64 characters and should not be one of the reserved identifiers: ptype, otype, start, opnum, queue, file, session, observe, or handle.
