For Version 1.0 only, there is one message store. You use a common message store.
For versions other than Version 1.0, there are multiple message stores. For each name, the checks are the same as for Version 1.0. You use either of the following commands to get the names:
# ncl show Message Store '*'
or
ncl> show Message Store *
See Table 8-22 for the XMS NCL entity checks.
