Creating an SDS Environment

Use a database backup of a primary system and then restore it (with no recovery) to create the secondary system, so that the integrity of the files is checked during the restore operation.

Some of the issues that you must consider in a production environment include the following.

• Selection of the appropriate journal synchronization mode, by using the SyncMode parameter in the [SyncDbService] section of the JADE initialization file. For details, see "Selecting the Journal Synchronization Mode for a Secondary Database" under "Synchronizing with a Primary", earlier in this chapter.

• Calculation of the bandwidth required for timely journal transfers.

• If using the journal switch synchronization mode, selection of appropriate parameter values for journal switches (for example, the [PersistentDb] section of the JADE initialization file JournalCloseAction, JournalMaxSize, JournalMinSize, and JournalSwitchInterval parameters).

• Backup of the secondary environment (including journals).

• Operational steps required to complete the transition of the secondary system to a fully functional primary system to which users can connect and use.
