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.

• To utilize certain features of the UCO, such as Entity Model Builder, 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 UCO, you must have the middleware proxy installed on the client machine to establish a connection with the middleware.

  UCO features that require the middleware or middleware proxy are:

  • Setting default utilization reasons

  • Selecting allowable utilization reasons

  • Validating utilization reasons

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