EdmiError edmiRemoteCloseDatabase(SdaiServerContext serverContextId,
SdaiString password,
SdaiInvocationId *edmiInvocationId);
Closes a remote EDMdatabase from a thin EDMclient. A closed EDMdatabase may not be accessed until it is reopened by the edmiRemoteOpenDatabase function. To ensure data consistency, this function should always be used to take down an EDMdatabase. Any open models or repositories will be automatically closed. If there exists an EDMserversession, it will be automatically terminated by a call to the sdaiCloseSession. Any connected thick EDMclients will be automatically disconnected by a call to the function edmiDisconnect.
