What advantages do I have?
Due to the usage of another database engine the new database is more reliable, significantly faster and more firmly established than the OrientDB database. It offers a lower memory and processing power requirements. By using database specific techniques database integrity can be guaranteed even better. Additionally, database specific processing steps were removed, so the duration of various processes is reduced even more. The new database offers a higher number of parallel access and is even more suitable for sending many parallel transfers.
What changes does the database update have on configuration and installation?
- The pool size configuration for high server load changes. Please consult the article Database Configuration.
- OrientDB specific parameters were removed from the Advanced Cryptshare Configuration.
Changed directory structure
All files needed for usage of the orientDB database were located in the orientDB subdirectory in the Cryptshare installation directory.
During the database migration the new database is written to the subdirectory db. Please note that when you used a link for the orientDB directory leading to another hard disk, you should set-up a new link for the db directory prior to the migration.
|When the migration finished successfully, the orientDB directory is deleted automatically. If you have important files inside this directory, please backup these files prior to the migration.|
The db directory is essential for using the Cryptshare server and must not be deleted.
How much time is necessary for migrating the database?
The migration heavily depends on the amount of previously sent transfers. The operation may take from several minutes to up to an hour.
Is all data migrated to the new database?
Transfers which expired more than 12 months ago and address book entries (when entering recipients in the Web App) which were used at last over 12 months ago are not migrated to the new database. As a result statistics data older than 12 months are not available any more after the migration. The Transfer Log only shows transfers which are not expired yet or were sent in the last 12 months. (When restoring the previous version, you are able to export the Transfer Log as a CSV file prior the migration, see Log View).
What issues may occur?
A migration finishes with one of three states:
- Migration with infos
- Migration with warnings
- Failed migration
