UpgradesTo connect to a database created with a version of Cloudscape prior to 3.6, Cloudscape must upgrade that database. Upgrading involves writing changes to the system tables, so it is not possible for databases on read-only media. (For information about upgrading read-only databases, see Read-Only Databases and Upgrading). The upgrade process makes the following changes:
NOTE: If Cloudscape is upgrading a database from a version before Version 3.5, it makes additional changes. NOTE: Be sure to read the Release Notes for information about Beta databases and upgrade. Recommended Steps Before UpgradingUpgrade happens the first time the new Cloudscape software connects to the old database. Before connecting with the new software, perform the following steps:
Upgrading a DatabaseTo upgrade a database, you must explicitly request an upgrade the first time you connect to it with Cloudscape Version 3.0 or higher. You explicitly request an upgrade with the database connection URL attribute upgrade=true. For example: jdbc:cloudscape:toursDB;upgrade=true Once the upgrade is completed, you cannot connect to the databases with an older version of Cloudscape. NOTE: Do not attempt to convert a database to a source (convertToSource=true) before upgrading its software version. Do not attempt to upgrade a database without backing it up. You can find out the version of Cloudscape with the following command: java COM.cloudscape.tools.sysinfo NOTE: Note that this is the product version, not the database version. It uses information in the jar files, so verify that only one Cloudscape product's jar files are in your class path when you run this tool. Synchronization Databases and UpgradesCloudscape supports automatic upgrade for synchronization databases. |
