System requirements

• All MES application objects—OCO, SRO, and UCO—must be at the same version; otherwise, incompatibility errors will occur.

• The Entity Model Builder must be installed. This can be installed during an MES installation with the Client applications.

• The Entity Model Builder requires that the MES middleware proxy be installed if the MES middleware is not installed on the local node.

• To utilize certain features of the OCO, you need to be able to access the MES database through the MES middleware. If the MES middleware is not installed on the same node where you are using the OCO, you must have the middleware proxy installed to establish a connection with the database.

For information on setting up or installing the middleware proxy, see the MES Installation Guide or online help.
