The CREATE DSA directive can return one of the following responses: New DSA database created. Configure the DSA. This means that the DSA has been created for the first time. Use the DSA configuration utility to give the DSA a basic configuration. DSA created successfully from memory image file. This means that the DSA has been created from a valid memory image file. DSA created successfully from memory image file. Schema Warning: The memory image file does not use the current schema. This means that the DSA has been created from a valid memory image file. However, the DSA detected that the copy of the schema in its memory image file is not the same as the one in /var/dxd. If the schema has been customized, you should force the DSA to read the new schema. Use the following commands: > DELETE DSA TO SNAPSHOT > CREATE DSA FROM SNAPSHOT This forces the DSA to read the schema during creation. DSA created successfully from snapshot file. This means that the DSA has been created from a valid snapshot file. On Tru64 UNIX systems, you should only use a snapshot file for management tasks that specifically require it. On the first occasion that you start the DSA after an upgrade, the DSA reads the existing snapshot file. After the first DIT check interval, or when you delete the DSA, the DSA creates a memory image file. It then reads and writes memory image files unless specifically instructed to read or write a snapshot file.
