Make CICS WUI dataset EYUWREP optional

The documentation at https://www.ibm.com/support/knowledgecenter/en/SSGMCP_5.5.0/configuring/cpsm/eyuadif.html states that the EYUWREP file "contains the Web User Interface server view and menu definitions".

I believe this includes any user groups and book marks but in essence, it only holds information required by the Web Browser interface and not the CMCI which is used by the CICS Explorer.
However, if this file is not available, for instance because of DASD issues, an initialising WUI server will issue:

EYUVS0005S CI2WUII CICSPlex SM Web User Interface initialization failed. (View repository and cache.)
EYUVS0004I CI2WUII CICSPLEX SM WEB USER INTERFACE TERMINATION COMPLETE.
DFHTM1715 CI2WUII CICS is being quiesced by userid SETUP in transaction COVG.

As the entire server is shut down, CICS Explorer and other CMCI base tools are unable to contact the environment but if the server had instead tolerated the file being unavailable these users would have been able to.

A possible solution is that if an initialising WUI server detects the file is unavailable, it issues a message to that effect (as now) but then closes the TCPIPSERVICE EYUWUI that it has already recreated or simply does not create it.

The possible solution above does mean that if the WUI server is also functions - for example to serve static web pages so anothe roption could be that with the repository unavailable any Web browser calls simply return a "temporarily unavailable" page.
