Returns info of about a remote EDMdatabase
...
from a thick EDMclient. The info returned is;
- The database version number.
- The database block size.
- The maximum number of models that may be stored in the database.
The EDMdatabase needs not be open when this function is invoked.
The main purpose of this function is to enable retrieval of this info from an EDMdatabase that cannot be opened due to incompatible block sizes and/or incompatible database versions within the EDMinterface of the EDMserver and the remote EDMdatabase.
If an EDMdatabase cannot be opened due to incompatible block sizes, the block size of the EDMserver must be set equal to that of the remote EDMdatabase.
If an EDMdatabase cannot be opened due to incompatible database versions, the remote EDMdatabase must be dumped by the EDMinterface of an EDMserver that supports the remote EDMdatabase version. Then Afterwards, it must can be restored by the EDMinterface of the new EDMserver. For details, see the EDMsupervisor commands Database>Dump and Database>Restore
When using the edmiRemoteGetDatabaseVersion on EDMdatabases older than version 4.7, the returned maxModelsInDB will be zero. This is because this feature was not implemented until version 4.7.
